"In the embrace of great Nurgle, I am no longer afraid, for with His pestilential favour I have become that which I once feared: Death."
- —Kulvain Hestarius of the Death Guard
The Death Guard are one of the Traitor Legions of Chaos Space Marines. They worship and devote themselves exclusively to the Chaos God Nurgle and as a result of his mutational "gifts" they have become Plague Marines; Astartes who are eternally rotting away within their power armour and infected with every known form of disease and decay but who are immune to all pain or minor injury.
When the XIVth Legion was first raised on Terra by the Emperor during the First Founding, its Astartes were known as the Dusk Raiders. After the XIVth Legion was reunited with its Primarch Mortarion on the world of Barbarus, he renamed the Legion the Death Guard.
The Death Guard are a Traitor Legion entirely steeped in the power of Nurgle, the god of death and plagues, their very essence the epitome of all that vile Chaos God stands for. Their bodies are hives of filth and decay, their ﬂesh eternally rotting away even as it is renewed by the ceaseless process of death and rebirth.
Once, however, the Death Guard were the strongest and most resilient of all of the Emperor's Space Marine Legions, the inheritors of the Primarch Mortarion in whose genetic image they were created. Mortarion grew to maturity on the world of Barbarus, a planet steeped in a toxic miasma where the human population cowered in the dark lowlands, fearful of the overlords that preyed upon them from their mountaintop keeps deep within the fog.
History does not record who or what these beings truly were, but it is certain they were more than, or at least other than, human. For one, they were able to breathe the deadly gases that make up the atmosphere, getting ever more deadly the higher the altitude, but they are said to have displayed other abilities too.
The abominable masters of Barbarus were somehow able to enslave or dominate the ﬂesh of the dead, and they preyed upon the cringing natives in the valleys below, ever needful of raw material to fuel the endless wars they fought against one another.
The infant Primarch was raised by one such overlord, Necare, the greatest of them all, who taught him the ways of war, yet would not answer his questions regarding the people who dwelled in the lowlands. When Mortarion defied his master and descended through the fog, which as a superhuman Primarch he could breathe, he found people, like himself, if weaker and existing in perpetual terror of the overlords who preyed upon them each night.
Though they were initially suspicious of him, Mortarion proved himself one of their kind, and moulded them into an army that at first defied the hunting parties of the overlords, and then turned the tables upon them. At length, the only one left was he who had been Mortarion's master, the High Overlord Necare, residing so high in the toxic strata that not even Mortarion could pursue him.
When the Emperor came to Barbarus, the people greeted him as their saviour, yet Mortarion was jealous and resentful of the adulation heaped upon this perfect stranger. Though his people could see that the Emperor was the Primarch's sire, he himself saw only the differences.
Where the stranger was noble of form and tanned of skin, Mortarion was pale and gaunt. When he refused to join him, the Master of Mankind issued Mortarion a challenge -- if the Primarch could defeat the last overlord of Barbarus, the Emperor would depart. If he could not, Mortarion must accept his fate and join the Great Crusade.
Mortarion accepted the Emperor's challenge and ascended into the toxic clouds, higher than he had ever travelled before. At length, he reached the grim keep of Necare and raged for the high overlord to face him.
Yet, even the Primarch's superhumanly enhanced body could not withstand the toxic atmosphere, but as he succumbed with Necare about to slay him, he saw the golden figure of the Emperor step between him and the high overlord, entirely unaffected by the poisonous air.
With a single stroke of his mighty, flaming blade, the Emperor felled the last overlord of Barbarus, and Mortarion acceded to his fate. Yet the Primarch found himself riddled with anger and resentment at his father for stealing away what he believed to be his rightful vengeance.
Once the Primarch was united with his Legion, it was found that the Death Guard, as they were renamed by their new lord, were amongst the most resolute and resilient of all the Legions. Mortarion's warriors were ever to be found at the centre of the battle line, their strength and determination the inheritance of their Primarch, making them the unbreakable core of any army of galactic conquest.
When the Horus Heresy plunged the galaxy into civil war, the warriors of the Death Guard found themselves becalmed in the Warp on their way to the Siege of Terra and assailed by Warp-born plagues so virulent that not even their legendary resilience could withstand them.
Soon, the entire Legion was beset by a sickness that bloated their bellies with corpse gas, caused ﬂesh to slough from their bodies and made these strongest and toughest of warriors into crippled wretches assailed by delirium.
Though none can say exactly what forces acted upon the soul of the Primarch of the Death Guard, whether he was already damned or whether he made his pact in some state of fever, he called out for deliverance, and his call must have been answered. When finally the Death Guard Legion's ﬂeet emerged from the Warp, its vessels and its warriors were entirely changed.
The once-gleaming white and grey armour was stained with filth, and the noble warriors were transformed into walking hives of death and abomination. Worse still, the "Plague Marines" of the Death Guard were now hosts for the most virulent afﬂictions that their new patron, the Plague God Nurgle, could concoct. Condemned to a deathless state of eternal decay, the Death Guard would spread their pestilent diseases the length and breadth of the galaxy for the greater glory of Chaos.
With the end of the Horus Heresy, the Primarch Mortarion led his Legion into the Eye of Terror, and while others had splintered into countless warbands, the Death Guard remained largely whole, thanks in no small part to their legendary strength and resilience.
Mortarion led them to a world that would become known simply as the Plague Planet, which he moulded into a new and despicable form, making it a virtual copy of Barbarous.
To this day, Mortarion's Death Guard launch their assaults through the Cadian Gate and into the galaxy beyond, sometimes in large bodies and at others lending strength to allied Chaos forces.
Wherever they travel they spread the joyful, exuberant poxes of Nurgle, gifting those who would know eternal life with the choicest of the Plague God's blessings. There have been numerous occasions when previously unknown plagues have swept the defence lines of otherwise static Imperial fronts, followed solar hours later by an overwhelming enemy advance. Many amongst the Imperial high command ascribe such instances to the Death Guard, and are fearful of what vile diseases they might concoct next.

The Emperor of Mankind sought to unite all of humanity under one banner following the Long Night of the Age of Strife, and end inter-human conflict. Once united, the Emperor intended to begin the next stage of His great plan to ensure human domination of the Milky Way Galaxy, which He judged to be necessary if humanity was to survive the never-ceasing threats to its existence embodied by Chaos, myriad xenos races and its own fragile human nature.
In time, when the Emperor's eye first began to fall beyond Terra, He began to raise new armies to fight His Great Crusade. He drew these new troops in part from the forces that had already unified Terra during the Unification Wars of the late 30th Millennium.
To carry out the Great Crusade and reunite all the scattered colony worlds of Mankind beneath the single banner of the Imperium of Man, the Emperor created the genetically-enhanced transhuman warriors of the Space Marine Legions. These forces would serve as the speartip of His Great Crusade that began in ca. 800.M30, bringing the light of the Imperial Truth and enforcing Imperial Compliance with the new regime on every human world encountered.
Warlords of Dusk
The origins of the Dusk Raiders can be found during the Unification Wars. The base human stock for the majority of the first Space Marine Legions to be raised came from Terra, and in the case of the XIVth Legion the main bulk of the gene-recruits used were drawn from the ancient and warlike clans of Old Albia, situated in southeastern Europe, where lay what once had been the ancient nation-state of Albania.
Indeed such was the suitability of their peoples for induction into the ranks of the Space Marines that recruits were drawn also to fill the ranks of the First Founding VIIIth and Xth Legions, the Night Lords and the Iron Hands, respectively.
Although this was to a lesser degree than the recruitment done there by the XIVth Legion which was by blood and culture shaped by the the warlords and techno-barbarians of Albia as well as the hand of the Emperor.
The recruitment of the sons of Albia served a twofold purpose; firstly, and most importantly, it drew off the cream of whole generations of strength from a Terran realm, now friend and ally to the Imperium but never fully trusted. For Old Albia, towering amid the northern Atlan wilderness, had once been a true rival of the Emperor for control of the destiny of Mankind.
By recruiting their brightest and best into the Legiones Astartes and the other growing Imperial organisations marked for war amid the stars, the Emperor ensured they could never threaten the Unification from within.
Secondly, it subsumed into the Emperor's forces all the martial traditions and bloodlines that had for centuries held much of Terra under their cruel grasp and had eventually overcome the Panpacific Empire under the rule of its Unspeakable King, Narthan Dume. Such a breed of relentless warlords and soldier-scientists was an invaluable resource that the Emperor was loathe to waste.
By the time the Unification Wars had begun, the warlord clans of Old Albia had thrown off the tyranny of the last descendants of the Unspeakable King, and did not readily bend their knee to the Emperor, for they refused to have another master in Dume's place. Instead the Albians met the Emperor's regiments of Thunder Warriors with their own battalions of steam-belching proto-Dreadnoughts and heavily armoured Ironside soldiers.
In battle after battle, the forces of the Unification were held in check, although at a shattering cost for the Albians, who would not give in despite the Imperial onslaught. Impressed with the Albians' martial temper and indomitable courage, the Emperor called for a ceasefire and sought victory over the warlord clans through peaceful negotiations, understanding that to crush them by force alone would entail a grinding war of attrition that would only serve to decimate His own forces and gain Him naught but a handful of ashes as a prize of war.
The Emperor pursued peace despite the protestations of His human counsellors and generals. Going before them, it is said, unarmed and clothed in white and crimson, the Emperor spoke to the warlords' parliament and laid before them His vision of a future Mankind reunited and ascendant, of tyrants toppled and nightmares slain.
He offered them glory amongst the stars and most importantly, redemption for many hundreds of years of kin-slaying and bloodshed. To the shock of many, the warlords of Old Albia accepted the Emperor's vision.
In doing so, the Albian clans became among the Unification's most zealous supporters, although still untrusted by many, lending their warriors and secrets long kept up for the Emperor's eyes alone. Most importantly for the future of humanity, the Albians sacrificed their sons to become the first Space Marines.
The XIVth Legion quickly developed in the use of tactics and methods of warfare that their Ironside forebears would have found utterly familiar, matched with a stoic temperament and gene-crafted aptitude which few doubted had been the Emperor's design all along. Operating in the role of heavy infantry, the Astartes of the XIVth Legion were experts at survival and endurance, and quickly gained a reputation among the other newly-forged Legions as relentless and disciplined fighters.
In defence they were stubborn and indefatigable, able to stand unwaveringly against the heaviest fire and hold their position against all comers to the last living body and Bolter shell if needed. In attack they systematically destroyed a given target, crashing upon an enemy in wave after wave of armoured bodies, excelling in close range fire-fights and bloody attrition.
Their grey and unadorned Power Armour began to carry the symbols of rank and decoration, now modified that once formed the armorial imagery of the Ironsides of Old Albia, and most tellingly their right vambraces, gauntlets and shoulder plates were painted the deep crimson of drying blood, now symbolising the red right hand of the Emperor's justice where once it had proclaimed the murderous reach of the Panpacific Empire's Unspeakable King.
As the XIVth Legion fought in the last days of Terran Unification and the first battles of the Great Crusade off-world, they were given the epithet of "Dusk Raiders" by those they fought and took it for their own. This name was a consequence of their use of the ancient Albian tactic of conducting major ground attacks at fall of night when the shift of light confused an enemy's watch, and gathering darkness would shadow an advance across open ground.
Such was the reputation the XIVth Legion garnered, in fact, that foes given an ultimatum of attack by the Dusk Raiders would often waver in their resolve, their soldiers panicking and deserting their bastions or throwing down their arms and fleeing at the coming of darkness rather than face the Astartes.
As relentless as they were in attack, the Dusk Raiders were known to be honourable opponents as well, who would hold to bargains struck for early surrender and honour symbols of truce. When such terms lapsed, however, and the die was cast for destruction, it was just as widely known that nothing would stay the Dusk Raiders' hand.
So the Dusk Raiders continued this course over the next eight solar decades as they fought on unwavering in the service of the Great Crusade. Still fatherless during this time as other Space Marine Legions gained their long-lost Primarchs until only a handful remained to be discovered, this "orphan" status further bred a self-reliance and a quiet, stubborn pride in the Dusk Raiders' self-forged character, and the martial triumphs of the XIVth Legion were many and enviable.
Their reunification with their Primararch though, when it finally came, was not to be the happy event that many had long hoped for, but instead it was to be a pall that fell across the Legion, and under its shadow the Dusk Raiders were broken down and remade, and only the Death Guard remained.
The Death Lord
When the 20 gestating Primarchs of the Space Marine Legions were scattered across the galaxy through the Warp from the Emperor of Mankind's secret gene-laboratory deep beneath the Himalazian (Himalayan) Mountains on Terra in a mysterious accident likely caused by the Ruinous Powers of Chaos, one came to rest on the planet Barbarus, a Feral World located in the Segmentum Tempestus that was wreathed in poisonous fog.
The population of the world was split into two groups: the controlling, apparently xenos overlords who were necromancers who possessed fantastic psychic powers, along with the human settlers, who had been trapped on the planet millennia before and were now forced to eke out an existence in the poison-free valleys of the planet, fearing the wrath of the overlords and their undead and mutant creations.
The Primarch-child was taken in by the most powerful of the overlords, the High Overlord Necare, who found him amongst the corpses of a battlefield, screaming and wailing where a normal human child would have suffocated and died long before.
The high overlord of Barbarus took the child in with the intention of creating a son and heir, naming him Mortarion -- the child of death.
Mortarion was kept in a fortress positioned at the limit of even his superhuman tolerance to the toxins in the air, while the high overlord moved his own manse to the highest peak of the world, beyond where even Mortarion could go.
He trained the child, who had a highly keen intellect and voracious appetite for knowledge; Mortarion learned everything from battle doctrine to arcane secrets, from artifice to stratagem.
However, the young Primarch's questions began to turn towards subjects the high overlord did not want to talk about, namely the pitiful creatures in the valleys that the many other overlords preyed upon for corpses to reanimate and bodies to corrupt.
The Deliverance of Barbarus
Finally, knowing he would be unable to find the answers he desired from his adoptive father, Mortarion was forced to break out of the fortress that had been his home and prison when he chose to save a caravan of humans who were being brought up from the valleys below to serve as experimental subjects for Necare's horrific experiments.
After killing several undead golem guards stationed at the gates of the fortress, Mortarion, guided by one of those he had saved, Calas Typhon, headed for the valleys of Barbarus. Breaking through the poisonous mists, Mortarion discovered that the prey of the overlords were in fact the same species as he, and he swore to deliver them from their oppression.
The people of Barbarus were slow to accept this pale, gaunt stranger from the mountains, but Mortarion was given a chance to prove his worth when mutant creatures enthralled to another warlord attacked the village. Seeing that the peasants were unable to effectively fight back, Mortarion joined the fray, wielding a massive harvesting scythe that made short work of the beasts.
The overlord smiled when Mortarion advanced upon him and withdrew to the apparent safety of the deadly fog, only to be pursued and butchered by this inhumanly resilient Primarch.
Accepted into the village without further reservation, Mortarion began to train the villagers in the art of warfare. Soon, representatives from other villages journeyed to learn from Mortarion, while the villages scattered across the valleys of the world were transformed into strongpoints. Mortarion travelled from settlement to settlement, teaching, building and defending his people.
He recruited the toughest, most resilient men and women he could find, forming them into small units that trained under his supervision. He enlisted the aid of blacksmiths, craftsmen and artificers to create special suits of armour that would allow men to travel through the poisonous fog.
As each battle in the mists was fought, Mortarion and his "Death Guard" would learn how to better adapt the armour, and themselves, to reach the more poisonous heights. Eventually, only one peak denied them access, the one on which Mortarion's adoptive father Necare had made his home.
The Coming of the Emperor
Despite his adoptive father being a ruthless necromancer, Mortarion felt reluctant to attack the being who took him in and called off the planned attack. Returning to the village, Mortarion's mood darkened when he found his people talking not of his victory but of the arrival of a benevolent stranger who promised salvation to the people of Barbarus.
Finding this stranger in conference with the village elders of his capital, Mortarion claimed that his people needed no outside help to slay their last oppressor. The stranger commented that even Mortarion and his Death Guard were having trouble pacifying the final overlord, and offered a challenge.
If Mortarion could defeat the high overlord, the stranger would leave. If not, Mortarion had to swear fealty to the stranger and the Imperium of Man he represented.
Ignoring the protests of his Death Guard, Mortarion left alone to confront his adoptive father, motivated by a compulsion to prove himself to the stranger below and also prove once and for all that he was better than Necare, who had often belittled him while growing up.
The confrontation was brief. The air surrounding the high overlord's fortress was so poisonous, that parts of Mortarion's special protective armour began to rot. He collapsed at the gates of the high overlord's citadel, bellowing challenges.
The final thing Mortarion saw before he passed out was Necare coming to kill him, then the stranger leaping between the two and slaying the high overlord with a single, flaming sword thrust.
When he recovered, Mortarion swore fealty to the stranger, who revealed himself to be Mortarion's true gene-father, the Emperor of Mankind. The Emperor granted Mortarion command of the XIVth Space Marine Legion, then known as the Dusk Raiders, who quickly adopted the name and regalia of Mortarion's original Death Guard.
However, the Emperor's slaying of his adoptive father proved to be a grudge Mortarion long held against his true father, for he had desired above all else to end the tyrant's life himself and prove himself the better.
When the Emperor took the chance to earn vengeance away from Mortarion, a seed of hatred and blame was placed within his heart that would in time blossom into rank betrayal.
A Mournful Unity
"You are my unbroken blades. You are the Death Guard. By your hand shall justice be delivered, and doom shall stalk a thousand worlds."
- — Primarch Mortarion, upon his unification with the XIVth Legion
True to his oath, Mortarion bent his knee to his new-found father as soon as he was sufficiently recovered to do so, although his final act of defiance on Barbarus would leave scars upon him both physical and mental that would never fully heal.
A skilled warlord in his own right, Mortarion was immediately given command of the XIVth Legion which carried his genetic inheritance, and did so on his own terms. Gathering them before him, a grim and spectral figure robed and bearing the great black scythe that had once belonged to his nightmarish foster-father, it must have seemed to the Terran-born Dusk Raiders that an ancient, graven image of the Grim Reaper had come before them as their new master.
His words were simple and delivered in a harsh whisper that never the less carried to each and every one: "You are my unbroken blades. You are the Death Guard. By your hand shall justice be delivered, and doom shall stalk a thousand worlds."
The Legion's name was then changed in accordance with this decree, and Mortarion's words were engraved above the airlock door of the Battle Barge Reaper's Scythe in honour of that moment. By this simple decree the Dusk Raiders were no more, and the records and annals from that day forward would carry this new name as one to strike fear into the hearts of Mankind's enemies.
The XIVth Legion's Astartes had been primarily Terran-born before Mortarion joined the Legion; after that time almost all of the Legion's Neophytes were drawn from the Feral World of Barbarus, beginning with the young Calas Typhon who had long served as Mortarion's chief lieutenant during his wars against the overlords and now became the Legion's First Captain.
This changed the culture and traditions of the Legion, so much so that by the last days of the Great Crusade in the early 31st Millennium, there were increasing tensions between the Barbarus-born Astartes and the Terran minority who remained in the Legion and who remembered the Dusk Raiders' earlier martial traditions brought out of Old Terra. These tensions became most clear in the period directly preceding the first battle of the Horus Heresy at Istvaan III, when approximately one-third of the Legion was judged by Mortarion to be likely to remain loyal to the Emperor when the Legion joined the Warmaster Horus in his rebellion against the Imperium. Many of these Loyalist Death Guard Astartes were Terran-born, former Dusk Raiders like Battle-Captain Nathaniel Garro of the 7th Great Company whose loyalty to the Emperor outweighed their devotion to their Primarch.
The Great Crusade
"Say what you like about the Fourteenth Legion. They are mean, ugly bastards but tenacious. There's no one else I'd rather have by my side in a war of attrition, and almost anyone else I'd rather have against me."
In the solar decades that followed the renamed XIVth Legion fought tirelessly in the service of the Great Crusade, never relenting in battle beneath their Primarch's gaze they pursued the liberation of Mankind with a fervour the Great Crusade had never known.
Their restless fleet ploughed the cold void from one campaign to the next, resupplying on the move, never pausing but to make war. The Death Guard did not garrison, they did not build, they only tore down and slew, coldly, determinedly and with the inexorable progress of a contagion or a tsunami wave, and worlds fell before them.
Over time Mortarion shaped the creed and practice of the Death Guard, his beliefs in many ways forming a natural extension of their own, beliefs and doctrine becoming ever more refined and extreme. At the heart of them was the unshakeable determination that Mankind should be free of oppression and terror. Such freedom could only be won in the Primarch's mind by destroying those that would shackle and devour humanity.
This was a war to be fought without mercy or limit, without restraint or relenting. The battle for the human future was one that could only be won by enduring any hardship, no matter how terrible, and not shirking from any act, no matter how savage in pursuit of victory. This single end, the liberation of humanity to Mortarion's creed, justified any means.
Mortarion took command of his new army with proprietorial severity. Though he was cold and aloof towards his sons, they worshipped him unquestioningly, and followed his teachings to the letter. Mortarion saw in them an opportunity to continue his labours upon Barbarus.
He would forge the Death Guard into perfect infantrymen, adaptable and self-reliant warriors who specialised in the use of durable weaponry that was easily maintained and re-supplied. The Death Guard were taught to choose the best ground, and then to grind their enemies down upon it with massed infantry formations.
They were the anvil to their allies' hammers, or else the bludgeon that battered the foe into submission. Some amongst Mortarion's brother Primarchs disparaged his tactics as blunt and unimaginative; in truth, the doctrines of the Death Guard were durable and efficient, and demonstrated a remarkable talent for grass roots martial organisation that earned the Death Guard a truly impressive honour roll of victories during the Great Crusade.
Mortarion's gene-seed made his sons hardy. Through his swiftly imposed regimens of toxin hardening and extreme environment tempering, the former Dusk Raiders became more durable than ever.
This inherent toughness only increased, for Mortarion recruited the bulk of his new Legionaries from Barbarus. The Death Guard were rightly proud of their indomitable physiology. They deployed into the most hazardous war zones where even other Space Marines hesitated to tread, and made widespread use of rad and Phosphex Weapons, alongside proscribed viral agents that soon earned them something of a dark reputation amongst their brothers.
Mortarion cared not for the distaste of his peers. His personal mission was the overthrowing of tyrants, beings such as the carrion lords of Barbarus, and he took pride that his sons could employ their own rugged strength to defend those too weak to protect themselves.
Still, for all their achievements, the labours of the Death Guard went largely unrecognised. Mortarion was far closer to his brother Horus than to his sire the Emperor, believing that the former recognised his worth far better than the latter ever would.
Worse, the longer they fought to shield the weak from oppression, the more the Death Guard became overly enamoured of their own fortitude, and dismissive of those too weak to protect themselves.
The Inheritance of Barbarus
Decades of endless battle changed the Death Guard, and over time the Terran influences on the Legion became less and less apparent, with the panoply and traditions of the Dusk Raiders and the Officio Militaris erased in favour of Barbarus' bleak creed of war.
The bare ivory-grey unpainted ceramite that Mortarion favoured for the Legion's Power Armour became increasingly less adorned, save for new murky-jade markings set to echo the corrosive-resistant swamp mud applied to coat the iron plates of the human warriors that had once served the Primarch of Barbarus, and shorn of older heraldry and Terran influence.
The martial stratifications of Old Earth's warmasters were done away with too, and eventually the Legion's Librarius was disbanded thanks to Mortarion's hatred of witchery such as that the hated charnel masters of Barbarus had once wielded.
Mortarion's hand and mind was at work everywhere remaking his Legion, from changing tactical doctrines to equipment procurement and, some say, behind the selection of candidates and changing practices in the Legion's Apothecarion, where he gained the latter knowledge to interfere.
With the prevailing conditions on Barbarus and the foul beings that more than likely still stalked the planet's fog-shrouded mountains and deep swamps, there were whispers that the human population that remained would have been better off if they had been euthanised or displaced to a "cleaner" world for the sake of the sanity of future generations.
Mortarion would have none of this, for Barbarus now belonged to his people, bought and paid for by generations of blood and terror, and its strongest sons would now serve as recruits for his new Death Guard.
As for the purely human Death Guard that had once fought for him against the overlords of Barbarus, many now became the masters of that world and a dread aristocracy they soon became, while the youngest and strongest took full or partial conversion into the Legiones Astartes, heedless of the high fatality rate that late induction carried with it, deemed a small enough price to pay to continue in the service of Mortarion their saviour.
With new recruitment at issue, Barbarus itself in a short span of years became little more than a factory of sorts to produce new recruits for the Death Guard Legion, and intake from other sources of recruitment to which the Legion had title dwindled to a mere handful, unless the pressure of fatalities in the field proved too great.
Mortarion's resistance to the use of bloodstock other than that of Barbarus wavered only because of the need to keep his Legion's strength battleworthy in his eyes. Recruitment solely from Barbarus was however aided by the high suitability of the planet's hardy feral population to the conversion process. The Legion's gene-seed seemed to amplify the uncommonly resistance to contagion and toxins in its Barbarus candidates to unheard of levels.
As fresh intakes of new Space Marines came in from Barbarus, the surviving core of Terran blood became a minority as the Great Crusade burned on across the stars, the Death Guard at the forefront of the fighting in the most hellish war-zones imaginable. Although second perhaps in their father's eyes, the Terran contingent remained stubborn in the ranks, hardened veterans and a force to be reckoned with in the Legion.
With the Legion drawing the majority of its Neophytes from Barbarus, this changed the culture and traditions of the Legion, so much so that by the last days of the Great Crusade in the early 31st Millennium, there were increasing tensions between the Barbarus-born Astartes and the Terran minority who remained in the Legion and who remembered the Dusk Raiders' earlier martial traditions brought out of Old Terra.
These tensions became most clear in the period directly preceding the first battle of the Horus Heresy at Istvaan III, when approximately one-third of the Legion was judged by Mortarion to be likely to remain loyal to the Emperor when the Legion joined the Warmaster Horus in his rebellion against the Imperium.
Many of these Loyalist Death Guard Astartes were Terran-born, former Dusk Raiders like Battle-Captain Nathaniel Garro of the 7th Great Company whose loyalty to the Emperor outweighed their devotion to their Primarch.
The Horus Heresy
Mortarion believed that victory in battle came through sheer resilience, and Horus, who used the strengths and weaknesses of the different Legions to create the most efficient fighting force possible, used his Legion in co-ordination with Mortarion's frequently. Mortarion and the Death Guard would draw out the enemy and tire them down, and then the Luna Wolves would strike.
This combat tactic worked brilliantly, and Mortarion grew close to Horus. The Lord of Death was a grim and driven Primarch, his breathing apparatus and great scythe an inseparable component of his aspect. The pallid, hairless Primarch was viewed by others as a freak, and was distant from all his brother Primarchs save Horus and Konrad Curze, the Night Haunter. Some even whispered that Mortarion was more loyal to Horus than he was to the Emperor; however the Emperor claimed that loyalty to Horus was de facto loyalty to the Emperor, for the two were that close. Events would prove the Emperor sorely mistaken.
When the Warmaster Horus turned to Chaos, it did not require much effort to drag Mortarion and his Death Guard Legion down with him. Horus had been one of the few Primarchs with whom Mortarion had felt comfortable, and as such he showed more loyalty to the Warmaster during the Great Crusade than to the Emperor Himself.
In addition to this, First Captain Calas Typhon, Mortarion's right-hand man, had long been a secret follower of the Ruinous Powers and eagerly manipulated the rest of the Death Guard into treading the path of damnation. Mortarion revealed his true colours during the scouring of Istvaan III, when he willingly sent potentially Loyalist elements of the Death Guard -- almost one-third of his Legion -- into Horus' trap. Once the Astartes who remained loyal to the Emperor were purged, the Death Guard then fought alongside their Traitor brethren during the Drop Site Massacre on Istvaan V.
The Doom of the Death Guard
During the subsequent assault on Terra itself, the Death Guard were part of Horus' invasion force. However, en route, the entire Death Guard Fleet became trapped in the Immaterium due to the actions of First Captain Calas Typhon, trapping them in a perpetual nightmare.
It was whilst on campaign with the Word Bearers Legion earlier in the Great Crusade that Typhon had learned of a different path for the Legiones Astartes to follow, a future where his hard-won but hidden psychic abilities would be a source of greatness instead of a taboo to be hidden from sight.
The foremost Chaplain of the Word Bearers, Erebus, inducted Typhon into the secrets of the Seven Pillared Lodge, one of the Warrior Lodges based on the beliefs of the feral peoples of Davin that had begun to spread throughout the Space Marine Legions in the later days of the Great Crusade. It was during this time that Typhon caught a glimpse of what the Space Marines could truly become if they shrugged off the yoke of the Emperor's ambitions.
Perhaps Typhon's revelation was instrumental in Mortarion's own fall to the Ruinous Powers; perhaps Mortarion would have walked a dark path on his own. Either way, the troubled Death Guard Primarch saw a worthy master in Horus, whereas in the Emperor he saw only a self-serving and pompous pretender who had stolen Mortarion's hard-won kingship over Barbarus in a single solar day.
As the Heresy that Horus initiated slowly but surely escalated into a galactic civil war, Mortarion ordered his fleet to head for Terra with all haste, intending for the Death Guard to join the other Traitor Legions in the destruction of the False Emperor. By this point, Calas Typhon served one master alone, and it was not his Primarch.
Typhon had seen to it that the fleet's Navigators were killed to a man after concocting a tale that they were traitors who had been receiving messages from Malcador the Sigillite, but reassured Mortarion that the psychic abilities he possessed would see them through their journey in the Empyrean safe enough.
Though he hated the concept of relying on witchery, Mortarion was left with little choice. The Death Guard fleet made transition into the Warp, and in the process damned themselves to an eternity of war as the puppets of a foul and ancient god.
In leading the Death Guard into the Warp, Typhon had delivered them into the clutches of his new master, Nurgle, the Lord of Decay. The strange tides of the Empyrean are notoriously fickle, and during their voyage the entire Death Guard fleet was becalmed. As their warships lingered, directionless and without hope, the cloying influence of Father Nurgle began to take hold.
The Death Guard were subjected to the terrible infection of the Destroyer Plague and Nurgle's Rot, as Nurgle's power managed to infiltrate the vessels of the XIVth Legion. It polluted the mechanisms of the vessels themselves as easily as it did the transhuman warriors within. Before long, fat devil-flies buzzed through the thickening miasma inside each warship. Where they bit at the desperate warriors trapped within, flesh turned to suppurating jelly.
The daemon-venom of their stings caused flesh to blossom into hard new growths. Bellies distended and eyes ran like cracked eggs; even Power Armour melded and flowed into strange new shapes. Here, the superhuman resilience of the Death Guard proved their enemy, for they could not simply die.
Instead, they were slowly, sickeningly transformed into Plague Marines, their souls claimed by Nurgle in exchange for a permanent release from their pain and suffering. Typhon, having orchestrated this grand corruption, was rewarded most of all.
Swelling in size, his skin and armour became one. Great funnels of pestilential bone burst from his body. Into these poured thousands of Nurgle's daemon-flies, gnawing him from the inside out until his rotten shell teemed and heaved with squirming life. Typhon became a great hollow colony of disease-carrying insects. The bone funnels that sprouted from his back coughed black decay as Nurgle's servants regurgitated the psychic energies pulsing through what was left of his herald's body.
Typhus, Chaos Lord and Host of the Destroyer Hive, had been born, most blessed and most cursed of all his repugnant kin. Since that bygone era, Typhus has visited a hundred thousand diseases upon the Imperium of Man. The Destroyer Plague is without doubt the most virulent of all, though fortunately its vector of daemonic insects means that it is of limited use when infecting entire star systems.
There was nothing so terrifying to Mortarion and the Space Marines of the Death Guard than watching the plague render their legendary resilience meaningless. The pestilence raced through the entire fleet, roiling in their guts, bloating and distending their superhuman bodies, transforming them into horrible, pustulent grotesques.
They were made corrupt within and sickening to behold without. They grew sicker by the solar minute, their incredible transhuman constitution their worst enemy as their bodies refused to die and they were wracked with the agony of their macabre transformation. What they endured was unimaginable, and none suffered worse than Mortarion. Whether he perceived in those terrible hours the loss of what he had once stood for, and the damnation he had wrought upon himself and his Legion, only Mortarion will ever know.
Unable to endure any longer, Mortarion offered his soul and those of all his sons to the Immaterium in exchange for deliverance from eternity trapped within the twisting corridors of Warpspace in constant, unendurable pain. A presence answered, as though it had been waiting all along. In the depths of the Warp the great god Nurgle, Lord of Decay and Father of Disease, claimed the Death Guard for his own.
What emerged from the Warp when the Death Guard fleet broke out into realspace bore little resemblance to that which had entered. The gleaming ivory armour and jade heraldry of the once-proud Imperial champions was no more, in its stead was a sickly pall of greenish hue. Bloated and corpulence replaced the sleek proud form of the Death Guard Astartes as every warrior was now pock-marked with boils, scabs and putrescent sores. Maggots writhed in their unhealing wounds and the air about them was clouded with swarming bloated black flies. They bore the foul stink of corruption.
Even their weapons and war machines had been mutated and were now powered by the sickly sorcery of the Plague God, glowing with lambent green Warp energy and oozing gangrenous pus. The Death Guard were now walking pestilence carriers; they had become the first Plague Marines.
Mortarion himself was also changed, growing taller and more gaunt, as if stretched on a rack. In return for rescue from the torments of the daemonic plague, Nurgle had set him on the path to daemonhood and transformed Mortarion into Nurgle's greatest daemonic servant: the Prince of Decay, the very image of death. Condemned to a deathless state of decay, the Death Guard would spread their pestilent diseases the length and breadth of the galaxy for the greater glory of Chaos.
In the end, Horus was ultimately defeated by the Emperor and cast down during the Siege of Terra, but unlike the other Legions, who splintered and fled into the Eye of Terror, Mortarion's Legion made an orderly withdrawal, force after force breaking themselves on the superating warriors of the Death Guard.
Mortarion led his forces, in an ordered formation, back into the Eye of Terror. Mortarion claimed the Daemon World known as the Plague Planet as his new homeworld and it proved to be an ideal base for launching attacks from out of the Eye into the physical universe.
He shaped it so well that Nurgle soon promoted him to become the greatest of his Daemon Princes. Mortarion had finally gotten what he wanted, a world of his own. He ruled over a toxic Death World of poison, horror and misery. But for better or worse, the Death Lord had come home.
Some of Mortarion's sons embraced their new form, believing in their arrogance that they had passed through the eye of the needle and proved themselves the only mortals worthy of Nurgle's patronage. Others hated the plague that had laid them low, the weakness it implied; for these warriors, nothing would suffice but to spread ruin and sickness until the entire galaxy was brought down to their level.
Others still were driven quite mad, taking on aspects of rambunctious glee or morose, entropic misery. Whatever the case, the Death Guard had become Nurgle's servants, body and soul, forevermore. In the millennia of war that followed, their devotion to their rancid deity would only deepen further.
The Post-Heresy Death Guard
Within the Eye of Terror, Mortarion's Plague Planet was soon moulded into a virtual copy of Barbarus, save this time he had taken up his adoptive father Necare's position as its chief tyrant.
Mortarion is still alive in the 41st Millennium, only recently reemerging into realspace for the first time since the Heresy to lead the assaults of the Death Guard on the Realm of Ultramar during the Plague Wars of the Era Indomitus.
To this day, Mortarion's Death Guard launches its assaults through the Cadian Gate and into the galaxy beyond, sometimes in large bodies and at others lending strength to allied Chaos forces.
Wherever they travel they spread the joyful, exuberant poxes of Nurgle, gifting those who would know eternal life with the choicest of the Plague God's blessings. Typhon (now called Typhus the Traveller) took a more active role in continuing the war against the Imperium by abandoning his master and striking out on his own, bringing the "gifts" of his patron to the Emperor's followers.
Typhus was especially active during the 13th Black Crusade, securing his own plague-ridden stronghold by the end of that conflict.
The Plague Wars
The Plague Wars were an attempt by the daemonic and Heretic Astartes forces of the Chaos God Nurgle, including the Daemon Primarch Mortarion and his Death Guard Traitor Legion, to conquer the Realm of Ultramar and add it to the Plague God's growing realm in realspace.
The Plague Wars began at some point after the birth of the Great Rift and the onset of the Noctis Aeterna and ended in ca. 111.M42, after the Primarch Roboute Guilliman successfully ended his Indomitus Crusade and brought Imperial reinforcements to defend Ultramar.
There is some debate amongst Imperial circles as to precisely when the Plague Wars began, or indeed which war zones they encompass. As with all the great works of Nurgle, this sprawling conflict has waxed and waned, undergoing periods of festering incubation and temporary remission before flaring to life again just as the warriors of the Imperium of Man believed that victory was finally theirs.
Even the origins of the Plague Wars are debated by the historitors of Ultramar, with the earliest accounts of hostilities claimed to have taken place even before the Great Rift split the stars.
Whatever the truth, it is known that the Plague Wars as the Imperium understands them have stretched across not only Ultramar -- where the forces of Nurgle have assailed the sons of Guilliman time and again -- but also the star systems to the galactic north of the Ultramarines' stellar realm now known as the "Scourge Stars."
It was amongst these formerly prosperous worlds that diseases such as the Crawling Pustulence, Eyerot, the Plague That Walks and the Oozing Pox erupted in riotous profusion after the Great Rift opened. Imperial defence lines were overrun by wave upon wave of trudging plague daemons and fanatical Chaos Cultists.
Corrupt demagogues spewed filth and falsehoods that saw Planetary Defence Force regiments turn upon their former comrades before joining the pestilent throng. Everywhere, the droning tally of misery was felt. Corpse mountains burned as Imperial authorities strove in vain to stem the tide of corruption that was drowning their worlds, until at last each planet in turn fell wholly into the grip of Nurgle.
It was these pox-riddled systems that Mortarion, Daemon Primarch of the Death Guard, claimed as his staging post for the invasion of Ultramar and his return to realspace, and from there that he launched his initial veiled sorties before his final offensive commenced.
Three loathsome spearheads pushed into Ultramar, attacking along a hundred fronts and bringing with them unnatural pestilence. The defenders of Ultramar -- Astartes and mortal alike -- fought bravely, but quickly lost ground.
Ultramarine Primaris Space Marines of the Ultima Founding arrived not long after the successful completion of the resurrected Primarch Roboute Guilliman's Terran Crusade from the Throneworld aboard Fleet Avenger to aid their Firstborn brethren, but even these transhuman reinforcements could only slow the attackers' progress.
By ca. 111.M42, over a hundred standard years after the start of the Indomitus Crusade, the Imperial defenders all across Ultramar were depleted in dozens of ground campaigns, while a Plague Fleet systematically destroyed the realm's Ultramar Defence Fleet and star fortresses.
Guilliman returned from the Indomitus Crusade after over a standard century of campaigning to stabilise the Imperium, and his deft and defensive manoeuvres bought time to launch what became known as the "Spear of Espandor" counterattack.
The combined plague armies were eventually fought to a standstill amongst the ruins of Iax, before Mortarion escaped with his forces back to the Scourge Stars under cover of a Virus Bomb attack, both because of his brother's staunch defence and because Nurgle's realm in realspace had come under assault by the forces of the Blood God Khorne.
In a brief respite from the work of safeguarding the Emperor's realm after Mortarion's defeat, Guilliman ordered the rebuilding and decontamination of Ultramar, as well as the establishing of new procedures for creating further Ultramarines.
It was not long before new Imperial Crusades called the Lord Commander of the Imperium away from Ultramar and back out into the dark galaxy. The Ultramarines then began the work of preparing their vengeance against the servants of the Dark Gods.
For ten thousand standard years, the Death Guard have mercilessly harried the servants of the False Emperor. They have spread plague and sickness across the stars, wearing their enemies down with relentless determination. They have ruined countless worlds, corrupted and despoiled armies beyond number, fighting the Long War in the names of Mortarion and almighty Nurgle.
Into Damnation, M30-M31
- Conquest of Galaspar (Unknown Date.M30) - This was the first major independent campaign conducted by the Death Guard after Mortarion took charge of the XIVth Legion. The conquest of the non-Compliant Hive World of Galaspar remains one of the most remarkable and brutal victories of the Great Crusade's course through the near reaches of the Segmentum Pacificus. Galaspar was a main Hive World located at the heart of a pocket empire consisting of 11 primary stars in cluster proximity. Galaspar and its satrap worlds had been for centuries thrall to a bureaucratic tyranny known simply as "the Order", which reduced its people to "labour units" to immediately be euthanised when they no longer had value to its system, and ruled through a mixture of crushing oppression and forced chemical dependence. When Imperial Explorator ships first entered the Galaspar Cluster they were immediately fired upon and all subsequent communication attempts were met with violence. The estimate of military resources to take this system was extremely high and such forces assigned to this Segmentum were unavailable at the time. The newly discovered Primarch Mortarion petitioned the Emperor for the opportunity to bring this system into Imperial Compliance. The Emperor acquiesced and allowed his newly discovered son to proceed. The XIVth Legion attacked without warning, the Death Guard fleet bludgeoning its way through the system's outer defences on a direct course for their target world. Caring nothing for secondary targets the Death Guard attacked the Hive World, taking the fight to the planet's surface. With their capital ships unleashing a hurricane of their own supporting fire, Mortarion descended through the fire and ash to the surface in the specially configured assault barque Fourth Horseman. The barque smashed into the upper structures of the primary hive-fortress causing a massive hive quake. The Death Guard then launched a massive wave of Drop Pods and Storm Eagle gunships in the barque's wake, descending to the surface like a force of nature. 11,000 grey-clad Space Marines with Mortarion's spectral figure at their head. Death had come to Galaspar. Slowly and inexorably the Death Guard proceeded to kill anyone that took up arms against them. The troops of the Order found themselves recoiling in terror at the onslaught of the unstoppable enemy. The Order's generals blindly continued to force their drugged slave-soldiers against the armoured giants. The resultant slaughter was on an unimaginable scale. There was no mercy and no unrelenting in the Death Guard's punishment, whether the enemy had to be run down in the poisoned, reeking hive-sumps or across the blasted rad-wastes, not one member of the Order survived. When the Imperial support fleet arrive they were horrified by the aftermath of the slaughter. The billions of humans "liberated" by the Death Guard were almost childishly eager to accept the Emperor's servants and adopt their ways. In the wake of the conquest of Galaspar, the cluster of worlds quickly capitulated with terrified speed, all willing to submit to Imperial Compliance under any terms as long as they were spared the reaper's scythe.
- Kajor Compliance (Unknown Date.M30) - On Kajor during the Great Crusade, the Death Guard Legion encountered a warrior race of humans that had fallen to barbarism. Extensive orbital surveys detected no trace of advanced technology, yet it took the XIVth Legion nearly six months to bring Kajor to submission. Though the Kajori were savages, armed with little more than blades and crude flintlock carbines, this feral race was able to hold the Death Guard at bay. They were able to do so because they possessed fell powers and unseen allies. Every night, creatures of witchery hunted in the shadows and killed for the joy of killing. Blood red hounds stalked the darkness of the forests with savage instinct, and juggernauts of thunder broke the Death Guard's lines with every charge. That anything could sunder a Death Guard formation was nothing short of a miracle. Mortarion's warriors had fought xenos species of every stripe and defeated them, but these were not creatures of flesh and blood. These were summoned into life by Kajori warlocks. These magi conjured lightning from their flesh, set fires with their thoughts and cracked the very earth with their shouted oaths. No power comes without a price, and with every victory the Death Guard won, they discovered what that truly meant. At the heart of every city they captured, Death Guard warriors found vast structures they came to know as Blood Fanes. Each one was a charnel house of bones and death. They destroyed every one, and with each one lost, the strength of their Kajori foes waned. In the end, the Death Guard ground down every ragamuffin force sent against them. Surrender was not in the Kajori's blood and they died to a man, destroyed by a ruling caste of warlocks who could not bear to relinquish their power. In quieter moments, Mortarion still thought of the Kajor campaign and shuddered. Mortarion would later recount the tale of this campaign during the Council of Nikaea as one example of many why he took a personal stance against sorcery and the use of psychic abilities.
- Krypt Prosecution (Unknown Date.M30) - The Compliance of Krypt was a relatively short campaign conducted during the Great Crusade by both the Death Guard and the Luna Wolves Legions against the Orks upon the frozen plains of the world of Krypt. Fighting together for more than a week across the frozen surface of the planet, the Legiones Astartes turned the blue ice dark with xenos blood. Battle-Captain Nathaniel Garro and his 7th Great Company were known to have fought alongside the Luna Wolves' Captain Garviel Loken and his 10th Company during this action.
- Preaixor Campaign (Unknown Date.M30) - This was an Imperial Compliance campaign that was jointly carried out by the Death Guard and the Emperor's Children Legions. During this campaign, Captain Saul Tarvitz of the Emperor's Children earned Death Guard Battle-Captain Nathaniel Garro's amity, proving to him that for all the reputation of Fulgrim's Astartes as overconfident peacocks, there were still men amongst the ranks of the IIIrd Legion that embodied the ideals of the Imperium. The two became Honour Brothers, carving a small eagle on each others vambrace by knifepoint, a sign of the battle debt they owed one another. When they clasped each others' vambraces in a warrior's handshake, the two eagles joined together to form the Imperial Aquila.
- Battle of Gyros-Thravian (Unknown Date.M30) - The Battle of Gyros-Thravian was a massive joint Imperial Compliance action carried out by three Space Marine Legions, composed of the Luna Wolves, Death Guard and Imperial Fists against the extremely powerful Ork Warboss Gharkul Blackfang, one of the most powerful Ork warlords ever encountered up until that time. Despite the strength arrayed against the vile Greenskin, it was the Imperial forces who were soon on the verge of defeat. It was then that the Emperor Himself, aboard His flagship Bucephelus, came to the aid of His sons. He personally led a force composed of 1,000 Legio Custodes into the heart of the mighty Ork horde. Blackfang was confronted by the Emperor and killed atop his Gargant while the Custodians proceeded to lay waste to the rest of the Greenskin horde. The Custodians accounted for the slaughter of the Orks, slaying over 100,000 of the savage xenos, with the loss of only three Custodians. Following their momentous victory, the Emperor commemorated the Custodians' sacrifice by engraving the names of the three fallen Custodians into His own personal Power Armour.
- Battle of Rennimar (865.M30) - This was a massive Imperial Compliance conducted by the Imperial Fists Legion against the massive Ork WAAAGH! of Over-Tyrant of Grel in the Rennimar System, who himself, was already under siege by both the Death Guard and Space Wolves Legions. Primarch Rogal Dorn, alongside Captain Archamus, the commander of his Huscarl Honour Guard, led a force of 10,000 Imperial Fists against the greenskin forces. Typical of the Imperial Fists Legion, they established heavy-walled bulwarks on the planet Rennimar, which enticed the Orks to hurl themselves and futilely smash against the Imperial Fists' stalwart defences. This enabled the combined might of the Legiones Astartes to utterly crush their xenos foes.
- Compliance of 154-4 (Ibsen/Caldera) (ca. 001.M31) - This was an unusual campaign of the Great Crusade that involved bringing the world of 154-4, known as Ibsen by its inhabitants, into Imperial Compliance. The Salamanders Legion, led by the Primarch Vulkan, was joined by the Death Guard and the Iron Hands Legions, both led by their own respective Primarchs. The world was undeveloped, and largely inhospitable to human life, but possessed valuable mineral deposits. However, the Imperial forces faced stiff resistance for control of the planet from the Eldar, who had placed a garrison upon Ibsen. The Eldar forces -- including Seers, Warlocks and other combat psykers -- could not have expected to defeat one Legion of Astartes, let alone three. The mystery deepened when the semi-feral, primitive human tribes inhabiting the planet seemed more sympathetic to the Eldar, or at the very least, not welcoming to their human liberators. The Salamanders and other Imperials defeated the Eldar relatively easily as expected. After the conquest, the Salamanders learned that the Eldar had been defending a network of menhirs which served as psychic nodes and that fed into a giant arch, where the final and most brutal confrontation between the Astartes and the xenos had taken place. The arch itself had been located thanks to a mysterious Remembrancer attached to the Salamanders, with whom Vulkan had had an unsettling conversation before the battle. After the slaughter ended, Vulkan saw the Remembrancer loitering by the arch and then suddenly disappearing. Following him, Vulkan and his elite Pyre Guard descended into the chambers beneath it, through a portal at its base. There they found a crude warding ceremony taking place, conducted by the primitive human tribal priests, who were ready to sacrifice an ancient Dark Eldar witch. Finally, Vulkan realised the truth: the arch was in reality a Webway portal (though none of the Imperials, including Vulkan, knew this at the time); Vulkan had seen a "gate" like this before, in his Nocturnean youth, when Dark Eldar repeatedly utilised such a portal to raid and pillage the planet. The Eldar had taken control of the portal by defeating their dark cousins, and in the process had freed the indigenous human population of Ibsen from the horrors of Dark Eldar raids; the Eldar had been seen by the native humans as liberators. Terrified by the defeat of their liberators at the hands of the Imperium, the natives had sought to sacrifice their Dark Eldar captive to ward off the inevitable return of her race; the mysterious "Remembrancer" who was nowhere to be seen had actually been the Emperor in disguise, who must have had a great interest in the particulars of this mission since He had ordered so many resources committed to it. Vulkan ordered Ibsen and its irredeemably corrupted population cleansed by flame. He renamed the scoured, Nocturne-like Dead World that remained Caldera. The world was now ready to receive new human colonists and to be exploited for the benefit of the Imperium.
- Jorgall Execution (005.M31) - The Jorgall campaign was carried out during the Great Crusade against a xenos race of humanoid aliens known as the Jorgall. They possessed a basic humanoid anatomy and also bled dark crimson coloured blood, similar in colour to that of a human's. But their brain and central nervous system was located inside their chest cavity. Nearly all Jorgalli featured extensive cybernetic physical enhancements to improve their physical forms and enhance their fighting abilities, such as hands replaced by lethal claws, feet replaced by wheels for rapid mobility and teleoptic cameras for eyes as well as sub-dermal protective armour. Some Jorgalli even had basic needler-type weapons implanted within the cavities of their bodies. They occupied the Tasak Beta and Fallon Systems in Imperial space. Elements of the 1st, 2nd and 7th Great Companies with Mortarion as the commander launched an assault into the main Jorgall cylinder world. This battleground was suited to the Death Guards' unique talents. The Jorgall breathed a mixture of oxygen and nitrogen with heavy concentrations of chlorine, a weak poison that a Death Guard Astartes' lungs could resist with little effort. First Captain Calas Typhon provided support for the Primarch while Commander Ignatius Grulgor penetrated the drive cluster and took out the control of the cylinder world's motive power centre. Battle-Captain Nathaniel Garro, alongside an elite cadre from the Sisters of Silence, neutralised the construct's hatcheries. Following their hard-fought victory, there were dissenting voices from the Adeptus Mechanicus contingent aboard the warship Spectre of Death petitioning Mortarion for a few days in which to loot the alien craft of technology. The Primarch, as was his prerogative, refused the request. The letter of Malcador the Sigillite's orders -- and therefore, by extension, those of the Emperor Himself -- was that the Jorgall incursion into the sector was to be exterminated and nothing more. The master of the Death Guard clearly saw no point of confusion in those orders. Nothing was to be left of the aliens.
- Battle of Istvaan Extremis (005.M31) - The elite 1st Company of the Emperor's Children Legion fought in concert with the Death Guard Legion's 7th Company under the command of Battle-Captain Nathaniel Garro against traitorous forces on Istvaan Extremis, the outermost planet within the Istvaan System. Whilst fighting against a powerful Slaaneshi psyker known as a Warsinger, Garro sustained serious injuries; crushing damage to his torso and arm as well as the loss of his right leg from the mid-thigh down. He was only saved from certain death by the timely ministrations of the Emperor's Children's Chief Apothecary Fabius. Taking stock of the desperate situation, the Emperor's Children Lord Commander Eidolon made use of a hitherto unknown ability -- a modified tracheal implant bonded with the Lord Commander's vocal chords, that allowed him to produce a nerve paralysing shriek similar to that employed by certain warrior breeds of the xenos Laer. This powerful ability killed the Warsinger and helped the Astartes carry the day.
- Battle of Istvaan III (Istvaan III Atrocity) (005.M31) - The Imperial Planetary Governor of Istvaan III, Vardus Praal, had been corrupted by the Chaos God Slaanesh whose cultists had long been active on the world even before it had been conquered by the Imperium. Praal had declared his independence from the Imperium, and had begun to practice forbidden Slaaneshi sorcery, so the Council of Terra charged Horus with the retaking of that world, primarily its capital, the Choral City. This order merely furthered Horus' plan to overthrow the Emperor. Although the four Legions under his direct command -- the Sons of Horus, the World Eaters, the Death Guard and the Emperor's Children -- had already turned Traitor and pledged themselves to Chaos, there were still some Loyalist elements within each of these Legions that approximated one-third of each force; many of these warriors were Terran-born Space Marines who had been directly recruited into the Astartes Legions by the Emperor Himself before being reunited with their Primarchs during the Great Crusade. Horus, under the guise of putting down the rebellion against Imperial Compliance on the world of Istvaan III, amassed his troops in the Istvaan System. Horus had a plan by which he would destroy all of the remaining Loyalist elements of the Legions under his command. After a lengthy bombardment of Istvaan III, Horus despatched all of the known Loyalist Astartes down to the planet, under the pretence of bringing it back into the Imperium. Initial attacks on the Choral City had washed away any feelings of unease, the release of the Loyalists' anger and hurt in bloodshed reassuring them that things were as they should be, and that their earlier misgivings were no cause for concern. Then Captain Saul Tarvitz of the 10th Company of the Emperor's Children had arrived with an incredible tale of betrayal and imminent attack. Many had scoffed at Tarvitz's warning, but some had immediately known the truth of it, and had fought to make their brothers realise their danger. As the monstrous scale of the betrayal sank in, the Loyalist Sons of Horus, World Eaters and Emperor's Children had raced to find shelter before the deadly viral payload struck the world intended to be their tomb. The Loyalists on the surface watched in horror as the first streaks of light lit up the sky and the detonations covered the clouds in thick starbursts of deadly viral agents. The screaming of the city as it died haunted them, as they could not even begin to imagine the horror that must have filled the minds of those who watched as the Life-Eater virus devoured the flesh of their loved ones, before reducing them as well to disintegrated hunks of rotted, dead matter. Many within the Loyalists' ranks knew what the deadly Life-Eater virus was, and they knew that within hours the entire planet would be a charnel house. Then the firestorm came as the tons of dead organic matter ignited and razed the surface bare of any signs of its former inhabitants, burning them to ashen flakes on the wind as it destroyed all in its path and howled across the surface of Isstvan III in a seething tide of flame. The Primarch of the World Eaters, Angron, realising that the virus-bombs had not been fully effective at eliminating all the Loyalists, flew into a rage and hurled himself at the planet at the head of 50 companies of World Eaters Traitor Marines. Discarding tactics and strategy, the World Eaters Traitors worked themselves into a frenzy of mindless butchery fed by their growing if unwitting allegiance to the Blood God Khorne. Horus was furious with Angron for delaying his plans, but Horus sought to turn the delay into a victory and was obliged to reinforce Angron with troops from the Sons of Horus, the Death Guard, and the Emperor's Children. Fortunately, a contingent of Loyalists led by Battle-Captain Garro escaped Istvaan III aboard the damaged Imperial frigate Eisenstein and fled to Terra to warn the Emperor that Horus had turned Traitor. On Istvaan III, the remaining Loyalists, under the command of Captains Saul Tarvitz, Garviel Loken and Tarik Torgaddon, another Loyalist member of the Sons of Horus, fought bravely against their own traitorous brethren. Yet, despite some early successes that delayed Horus' plans for three full months while the battle on Istvaan III played out, their cause was ultimately doomed by their lack of air support and Titan firepower. During the battle the Sons of Horus Captains Ezekyle Abaddon and Horus Aximand were sent to confront their former Mournival brothers, Loken and Torgaddon. Horus Aximand beheaded Torgaddon, but Abaddon failed to kill Loken when the building they were in collapsed. Loken survived and witnessed the final orbital bombardment of Istvaan III that ended the Loyalists' desperate defence. To prove his worth and loyalty to Lord Commander Eidolon of the Emperor's Children -- and thus to his Primarch, Fulgrim -- Captain Lucius of the 13th Company of the Emperor's Children, the future Champion of Slaanesh known as Lucius the Eternal, turned against the Loyalists that he had fought beside because of his prior friendship with Saul Tarvitz. Lucius slew many of them personally, an act for which he was then accepted back into the Emperor's Children Legion on the side of the Traitors. In the end, the Loyalists retreated to their last bastion of defence, only a few hundred of their number remaining. Finally, tired of the conflict, Horus ordered his men to withdraw, and then had the remains of the Choral City bombarded into dust for a final time from orbit.
- Drop Site Massacre of Istvaan V (566006.M31) - The world of Istvaan V was the location of the infamous Drop Site Massacre where the Traitor Legions of Horus redeployed following the virus-bombing of their own Loyalist members at Istvaan III at the start of the Horus Heresy. Upon learning of the terrible atrocity Horus had committed, the Emperor deployed seven Loyalist Legions of Space Marines to bring Horus to account for his actions. The Iron Hands, Salamanders and Raven Guard made up the first wave of the attack, but were pushed back by the superior tactics of Horus' maddened Chaos Space Marines. The Loyalist reserves were called in, but the four Space Marine Legions comprising them -- the Iron Warriors, the Alpha Legion, the Word Bearers and the Night Lords -- had also secretly betrayed the Emperor and were prepared to follow Horus and swear themselves to Chaos. The three Loyalist Legions were almost annihilated in the resulting crossfire but several thousand survivors from each Legion managed to escape off-world, though they were too decimated to play much of a further role in the defence of the Imperium from Horus' betrayal. During this engagement, the Death Guard made extensive use of surprise attacks from concealed positions, mines, Alchemical Weaponry and heavy sustained close-range fire, principally against the Salamanders Legion, and were met in resolve and fury by Vulkan's Legion, incurring massive casualties on both sides. During the ensuing slaughter, Fulgrim came face-to-face with his former brother and closest friend, Ferrus Manus. The two Primarchs engaged in a titanic struggle, but in the end The Gorgon was mortally wounded, and at the urging of the Laer daemonblade that he always carried, Fulgrim beheaded the Iron Hands' Primarch. The civil war that began in earnest at Istvaan V pitched the whole Imperium into the seven years of anarchy, death and chaos remembered only as the Horus Heresy.
- Second Battle of Prospero (007.M31) - After White Scars Primarch Jaghatai Khan refused to aid Leman Russ and his battered Space Wolves fleet against the Alpha Legion in the Alaxxes Nebula, he finally arrived to the Thousand Sons' ravaged world of Prospero seeking answers for himself. Teleporting down to the planet's surface with a small Keshig Honour Guard detachment, Jaghatai explored the ruins of the planet's former capital of Tizca. During his explorations, the Primarch became separated, and soon found himself within a network of subterranean caverns, where he was confronted by the ætherial projection of his brother Primarch Magnus the Red. Magnus implored his brother to choose a side and to not trust their father, the Emperor. Finding the answers he sought, Jaghatai made his way towards the surface and was reunited with his Keshig, who were soon beset by Mortarion and a contingent of elite Deathshroud Terminators. The Death Guard Primarch tried to persuade his brother to join the Warmaster's cause, but Jhagatai refused, and proceeded to fight his brother, gravely wounding him and forcing him to withdraw. Teleporting back aboard his flagship, the Primarch then ordered his fleet to depart for Terra.
- Persecution of the White Scars (007-011.M31) - For the next four years, the Death Guard continuously harried the White Scars fleet which was trapped far from Terra due to the massive Warp Storm, known as the Ruinstorm, which made all long-distance Warp travel impossible. Seeing no other choice, the White Scars were forced to begin a hit-and-run guerilla campaign against the Traitor Legion forces to slow their advance on the Throneworld. The White Scars proceeded to lose nearly one-fifth of their fighting forces over the course of the next few years. After nearly four years, the Death Guard, working in conjunction with a large Emperor's Children contingent commanded by Lord Commander Eidolon, knew the White Scars Legion would soon face inevitable defeat and destruction at their hands. Having adjusted to the Vth Legion's tactics, it became apparent to Jaghatai Khan that they were slowly being boxed in. Desperately, the White Scars sook out one last approach, and discovered a hidden Navigator facility within the Catallus Warp Rift. Within they found the Dark Glass artefact -- a far-less powerful prototype of the Emperor's own Golden Throne device, which was capable of accessing the Webway. The White Scars Stormseer, Targutai Yesugai sacrificed himself, when he sat upon the Dark Glass throne in order to open a temporary path through the Webway, which allowed the White Scars to escape from the massive Traitor fleet, and exit at the outer edge of the Segmentum Solar.
- Battle of Perditus (008.M31) - When the Dark Angels received intelligence from an Astropathic message from the nearby Perditus System, they acted accordingly and moved to intercept. Upon arrival, they interrupted the month-long conflict between the Iron Hands 98th Clan-Company, led by Casalir Lorramech and a large Death Guard contingent, led by First Captain Calas Typhon. Both sides had been fighting over an ancient sentient device, known as the Tuchulcha Engine. This device was a part of a triumvirate of similar sentient devices (another being the Ouroboros and a third, unnamed engine) which when combined could create temporal rifts that bridges space and time. On its own, the Tuchulcha was capable of precise and extremely efficient Warp jumps. Faced with the prospect of fighting the entirety of the much larger Ist Legion fleet, both sides retreated from the planet's surface at the Lion's request. Wary of both sides' motives, especially First Captain Typhon's, the Lion prevented the device from falling into the Death Guard's hands for his own nefarious ends. He then proceeded to serve his own ambitions and requisitioned the device for his own use. The Lion then ordered the destruction of Perditus, much to the consternation of both commanders.
- The Incident at Dwell (009.M31) - Having escaped death at Arissak, one of the the surviving Shattered Legions cells of the Iron Hands commander Shadrak Meduson launched a daring assassination attempt on Warmaster Horus at Dwell. With his brother-Primarchs Fulgrim and Mortarion at his side, Horus prevailed, but having had the true threat revealed to him, granted Captain Tybalt Marr permission to take any action he deemed appropriate to eradicate the so-called "Shattered Legions".
- The Battle of Molech (009.M31) - Horus led a massive invasion, which included the Sons of Horus and Death Guard Legions, against the Fortress World of Molech in order to obtain the power of the Emperor by means of a hidden Warp portal that led into the Realm of Chaos itself. It was during the height of this conflict that Knight House Devine turned against the Imperium and joined the invading forces, betraying the defenders to their deaths. A force of the elite Knights-Errant, a secretly founded Order of Loyalist agents, was dispatched to Molech by Malcador the Sigillite to prepare the way for a direct assault by the Space Wolves against the Warmaster's flagship. Having recently won the full blessings of the Ruinous Powers, Horus was undefeatable and only a handful of Knights-Errant escaped to bring news of his redoubled strength back to Terra.
- Battle of Terra (014.M31) - As the events of the Horus Heresy neared their tragic conclusion nine standard years after the fateful betrayal at Istvaan III in 005.M31, those Loyalist Legions not committed to the defence of Terra raced through the Warp, converging on the homeworld of Mankind. The Traitor Legions also massed above Terra to assault the Imperial Palace. The Battle of Terra was the final confrontation of the Horus Heresy that raged on Terra itself between the Forces of Chaos led by the Warmaster Horus and the Loyalist armies of the Imperium of Man led by the Emperor of Mankind Himself. When Horus was en route to launch his final siege of Terra itself, the warriors of the Death Guard found themselves becalmed in the Warp and assailed by Warp-born plagues so virulent that not even their legendary resilience could withstand them. Soon, the entire Legion was beset by a sickness that bloated their bellies with corpse gas, caused flesh to slough from their bodies and made these mightiest of human warriors into crippled wretches assailed by delirium. Though none can say exactly what forces acted upon the soul of the Primarch of the Death Guard, whether he was already damned or whether he made his pact in some state of fever, he must have called out for deliverance, and his call must have been answered. When finally the Death Guard Legion's fleet emerged from the Warp, its vessels and its warriors were entirely changed. The once-gleaming white and grey armour was stained with filth, and the noble warriors were transformed into walking hives of death and abomination. Worse still, the "Plague Marines" of the Death Guard were now hosts for the most virulent afflictions that their new patron, the Plague God Nurgle, could concoct. Condemned to a deathless state of decay, the Death Guard would spread their pestilent diseases the length and breadth of the galaxy for the greater glory of the Plague Father. The Loyalist forces ultimately proved victorious in their defence of the Imperial Palace, though only just barely, and Horus was ultimately slain by the full psychic powers unleashed by the Emperor on the deck of his massive Battle Barge the Vengeful Spirit, though the Master of Mankind was mortally wounded and had to be interred within the cybernetic life support mechanisms of the advanced psychic augmentation technology known as the Golden Throne. Those Imperial vessels which pursued Mortarion's plague fleet from Terra followed a trail of devastated worlds, where corpses were piled high, survivors pleaded to be allowed to die to escape their nightmares and, ominously, thousands more were simply missing, never to be seen again. Eventually, after countless atrocities, the Death Guard reached the Eye of Terror where they and their fellow traitors hid from the vengeance of the Imperium. Within this hellish realm, Mortarion claimed the Daemon World which would become known as thePlague Planet as his own; its location near the fabric of reality was ideal for launching new strikes into the Imperium and across the galaxy as the Death Guard continued their Long War against the "Corpse Emperor" and his false Imperium.
- Rise of the Plague Planet (Unknown Date.M31) - Alone amongst the Traitor Legions, Mortarion's sons retreat from Terra in good order. They reave a path of desecration and atrocity across the Imperium, before finally plunging into the horrific sanctuary of the Eye of Terror. For his victories during the Heresy, his unshaken faith, and for the singular achievement of holding his Legion together in the face of the Imperium's vengeful ferocity, the Plague God gifts Mortarion with daemonhood and a world to rule over as his own. So is a new Barbarus created near the fringes of the Eye of Terror, a more nightmarish hellscape than even Mortarion's homeworld once was.
Time of Remission, M32-M41
- Galactic Respite (Unknown Date.M32-M41) - The Death Guard engage in a series of brutal wars against their erstwhile allies in the Eye of Terror. Though they prevail time and again, this territorial campaign consumes Mortarion's entire focus. Thousands of standard years will pass in realspace during which the Death Guard are rarely sighted by the servants of the Imperium.
- Bane of Change (Unknown Date) - During fighting against the Tzeentchian Chaos Cultists of the Lost Spiral on J'kadis, Death Guard Lord Glottox unleashes his feared Drone Hive. Seven thousand Foetid Bloat-drones thrum into battle, shrugging off the agile strikes of disc-riders and Burning Chariots as they close on their target. Ploughing through ferocious enemy fire, the drones shield the lumbering Dark Mechanicum plague bombers at their heart, which rain rot-diffusion warheads on the Tzeentchian Twystshrine and corrode it away to crystalline ruins.
- The Green Death (Unknown Date) - The infected Ork warbands invading the Ecclesiarchy Shrine World of Sanctia evince a terrible new barbarism. They fall upon the planet's defenders and consume them bodily, devouring the living and the dead alike, as if compelled by a daemonic hunger. Bloating and swelling, the Orks become obese monstrosities that can move only at a snail's pace. Puzzled by this strange reprieve, the Adepta Sororitas systematically purge the Orks with flame and Bolter. It is then that Mortarion and the Death Guard of the 7th Plague Company make planetfall. The Daemon Primarch looms over the bodies of the Orks as he stalks to the front lines. At his passing, each Greenskin bursts apart in a shower of foul fluids, and dozens of Nurglings spill out from their remains to follow their master. Sanctia falls to the Green Death within twenty solar hours of Mortarion's arrival, and the plague spreads across the Ecclesiarchy-held star system.
- The Smog of War (Unknown Date) - Vectoriums of the 2nd Plague Company, including the Rusted Claws and the Tainted Lung, engage the Iron Hands of Clan Kaargul and Astra Militarum armoured regiments on Tsarvia II. As the grinding tank war starts to turn against them, the Death Guard set light to the sprawling chem-works of Tsarvia Secundus. Malignant Plaguecasters channel the resultant fumes into banks of corrosive smog that wreathe the Death Guard tanks and dissolve the hulls of their Imperial foes. Able to withstand the hideous conditions in a way that their enemies cannot, the Death Guard soon crush Tsarvia II beneath their armoured treads.
- The Black Crusades (M31-M41) - Over long centuries, Abaddon the Despoiler spends the blood of countless followers in battles against the Imperium. Though seemingly unconnected, each so-called Black Crusade is in truth part of a far grander plan that eventually triggers the opening of the Great Rift in 999.M41. During this period, the new Warmaster of Chaos forges numerous pacts with the greatest Chaos powers, amongst them the Death Guard. Mortarion's scorn for Abaddon is obvious, but the Daemon Primarch cannot ignore his successes, and so sends warbands of his sons to aid in several of the Despoiler's campaigns. Typhus aids Abaddon more readily, fighting alongside him more than once, and using his attacks upon the Cadian Gate as an opportunity to spread the seeds of the Zombie Plague far and wide.
- Seed of Doom (Unknown Date.M41) - Confounded by the magnatropic defence matrices of the Forge World Takbandrha, an invasion force of the 5th Plague Company is all but annihilated. Only a single Death Guard Sorcerer makes it to the Forge World's surface, vanishing into the gloomy serf-warrens of the underfactorums. Summoning daemons through ritual sacrifice and desecration, the Sorcerer conjures a foul new army whose burgeoning corruption draws yet more of their number through the veil, their numbers growing exponentially. Though the initial Death Guard attack causes the merest pinprick in the hide of this Imperial world, the virulent doom that spreads from it soon sees Takbandrha sicken and die.
- Scouring of Makenna VII (Unknown Date.M41) - This was a mutual campaign to conquer the Imperial world of Makenna VII, which was fought by the Forces of Chaos under the supreme command of the Warmaster Davroth, a powerful Chaos Lord of the Word Bearers Traitor Legion. Lord Festardius, a powerful Chaos Lord of the Death Guard Legion, made an alliance with Davroth during the Horus Heresy. Although during the Long War against the Emperor both Chaos Lords have fought separately, Festardius sought to rekindle their ancient comradeship. He learned of Davroth's ultimate goal and offered his support, in return for the rulership of Makenna VII once Davroth moved on to his next conquest. Festardius' Death Guard warband veterans saw much fighting, proving invaluable to Davroth's plans. The planet was eventually overrun by the Forces of Chaos, and the Ruinous Powers laid claim to yet another Imperial world.
- Achilus Crusade (777.M41) - Blight Master Ussax, a powerful Veteran of the Death Guard Traitor Legion and a known member of the Daemon Primarch Mortarion's inner circle of Chaos Sorcerers, has continued to plague the Jericho Reach during the Imperium's ongoing Achilus Crusade. Travelling from one warzone to the next, from each battlefield, Ussax gathers up a grim and unspeakable harvest from the dead and dying. Concocting his latest ague from these deceased corpses, Ussax then releases it upon the next battlefield he attends, once more harvesting the bodies of the victims.
Time of Infection, M41
- Siege of Vraks (813-830.M41) - The Siege of Vraks was an Imperial military campaign fought over the course of 17 standard years to retake the Imperial Armoury World of Vraks Prime from the heretical Forces of Chaos led by the Apostate Cardinal Xaphan. These forces included several vectoriums of the Death Guard Traitor Legion such as the Apostles of Contagion, Lords of Decay, The Purge, and The Tainted. Descending into the midst of the hideous trench war, the Death Guard unleash virulent bioweapons upon the Imperial forces and begin a chain of events that result in a full-blown daemonic invasion. At the conclusion of this painfully long and regrettable campaign of attrition, 14 million Imperial Guardsmen had been lost and Vraks Prime's entire original population of 8 million souls had been consumed in the violence or exterminated after they fell to Chaos corruption. The world was then declared Perdita (a Dead World) by the Imperium and placed under an interdiction to cordon it off from the rest of human space as ordered by the Ordo Malleus' Inquisitor Lord Hector Rex.
- The Battle of Konorvin (901.M41) - The Grey Knights meet the Death Guard on the planet of Kornovin, the battle representing the culmination of an ancient plan to banish Mortarion forever. The Daemon Primarch's might is too great, however; after Mortarion fells Supreme Grand Master Geronitan in battle, the newly appointed Supreme Grand Master Kaldor Draigo is forced to work a desperate banishment ritual that hurls Mortarion's spirit into the Warp for many standard years. It is a pyrrhic victory at best, a respite that Mortarion uses to gather fresh forces and plot his next and greatest invasion of realspace.
- Hive of Horrors (Unknown Date.M41) - Typhus infests Hive Pandorial with the Zombie Plague, departing before Imperial retribution can occur. Instead of encountering a hated and ancient enemy, the courageous men of the Astra Militarum's Necromundan Spyders find themselves plunging deep into the shadowed horrors of a hive city filled only with the shambling corpses of those they came to avenge.
- Curdled Faith (Unknown Date.M41) - Attacked by T'au pacification cadres, the Imperial Shrine World of Calendhula remains defiant behind their shield of faith. Their defence falters, however, when the world's statues weep tears of filth and their water sources turn to gelid slime. As battle rages and the body count spirals, hellish portals yawn in Calendhula's depths, and the warriors of the 4th Plague Company march out. Led by the daemon known as the Eater of Lives and bolstered by capering daemons, they crush both the Imperial and T'au forces to claim the world for Nurgle.
- Battle of Anvarheim (Unknown Date.M41) - Imperial Navy ships of Battlefleet Obscurus pursue an outnumbered Plague Fleet through the Kuidus Belt. After a savage battle, the last surviving plague ship manages to perform a full combat drop onto the world of Anvarheim before breaking up in the planet's atmosphere. Emerging from their drop-craft, the vectorium known as the Putrid Choir tear their way into Anvarheim's polar fortress city -- Jotungaard -- and seize the complex for themselves. Expecting swift victory, wave after wave of Imperial forces descend upon the complex. Each is broken in turn upon the tenacious Death Guard defences. A prolonged siege develops amidst bitter snowstorms tainted by Nurglite plague spores, and as the fighting stretches into solar weeks, then months, the Putrid Choir's entropic dirge echoes endlessly across Jotungaard from the fortress' Vox emitters. At last, three standard years after the Putrid Choir first descended upon Anvarheim, the remaining Imperial forces -- starved, diseased and deranged -- flee for the stars, leaving the Death Guard warriors sorely depleted but victorious within their contaminated fastness.
- Pandorax Campaign (959-961.M41) - In the Demeter Sector, Abaddon the Despoiler led an alliance of Traitor Legions, including his own Black Legion and the Death Guard, in an invasion of the Imperial world of Pythos, the location of an ancient hidden gateway to the Warp. Another piece in his dark design to bring an end to the Long War, the Warmaster of Chaos fell upon the world with a small force of Daemon Engines and infernal war machines. In the space of a few bloody solar days the major hive cities were overrun and the local Planetary Defence Forces crushed beneath the might of the combined Traitor Legions. Only a small contingent of Catachan Jungle Fighters, the CLXXXIIIth Catachan Regiment of the Imperial Guard, managed to escape the destruction, trekking through the world's inhospitable jungle to the relative safety of the nearest mountain range. Abaddon commenced the complex rituals and sacrifices that would open the Damnation Cache, a portal between realspace and the Warp, breaking open seals that had remained untouched since the time of the Horus Heresy. Heeding the impassioned cries for salvation from Pythos, the entire Dark Angels Chapter, led by Azrael himself, came to the defenders' aid. Supporting these Space Marines were Grey Knights dispatched from Titan to deal with the escalating daemonic incursion and the dire peril that the Damnation Cache posed. Both Imperial forces smashed through the Traitor Legion blockade around Pythos, in an epic void battle that pitted the finest warships of the Imperium supported by The Rock, the Dark Angels' mobile fortress-monastery, against the ancient vessels of the Traitor Legions. After the Chaos warfleet was finally driven from orbit and back into the void, the Space Marines were able to send their troops down through the atmosphere, bringing war to its ruined hives and hostile jungles. Failing to allow this distraction to draw him away from the awakening of the Damnation Cache, Abaddon sent an alliance of Legions to hold the Loyalists at bay. Before either the Dark Angels or the Grey Knights could stop him, Abaddon finally opened the portal to the Warp, daemons spilling out across Pythos. The ensuing conflict devastated the world as reality itself bent and buckled under the raw power of the Empyrean. The unleashed energies created rampant psychic phenomena, and Space Marines fought under boiling skies of blood and in rolling clouds of keening spirits. All across the Demeter Sector, latent psykers were awakened to full and terrible awareness and rebellions sprung up like cancerous boils on dozens of Imperial worlds in the region. After a long and bitter struggle, a squad of Grey Knights managed to reach the Damnation Cache and to close the Warp portal. Starved of their daemonic allies, the Traitor Legions were forced onto the defensive and finally into retreat. Abaddon's forces left Pythos, escaping the vengeance of the Imperium once again, but the world had been irrevocably tainted by the touch of the Warp, its once proud cities and vast wilds twisted into a nightmarish hellscape. Before the portal was closed, however, Abaddon took with him a psyker, rumoured to be of prodigious strength and the bearer of a unique gift that would aid the Warmaster of Chaos in his forthcoming 13th Black Crusade. This conflict as a result is remembered in Imperial records as the Pandorax Campaign.
- Paradaxian War (Unknown Date.M41) - A hauling barge delivering heavy ores to the Forge World of Paradax opens its ramp only to disgorge Plague Marines and Foetid Bloat-drones led by elements of the Weeping Legion. Bolters roaring, the Heretic Astartes smear diseased gore onto the machineries around them, spreading sanguous flux and corrupting the Forge World's Machine Spirits. Leading a growing army of proto-Daemon Engines and possessed Servitors, the Weeping Legion begins the grinding horror known as the Paradaxian War.
- Plague and Shadow in Commorragh (Unknown Date.M41) - A plague of flies erupts within the war-torn Sec Maegra district of Commorragh. From amidst the fly clouds stride Plague Marines of the Mouldering Claw, who meet the Drukhari in savage battle before vanishing as mysteriously as they arrived. Several metaphysical plagues emerge in their wake to trouble the Dark City.
- Stay of Execution (Unknown Date.M41) - On the killing fields of Vindor, the Death Guard decide to allow the last survivors of the Imperial Vindorian garrisons to flee, thus spreading Nurgle's gifts of plague and despair. Unwilling to watch perfectly good slaves escape, however, their Emperor's Children allies pounce, only for the Plague Marines to bar their path. A furious battle erupts between the followers of Nurgle and Slaanesh, while the diseased Vindorians scatter to the four winds, taking Nurgle's dubious blessings with them.
- 13th Black Crusade (995.999.M41) - The Death Guard Traitor Legion deployed in its entirety to take part in Abaddon the Despoiler's 13th Black Crusade against the Imperial Fortress World of Cadia. This resulted in the largest mobilisation of both Imperial and Chaos forces seen in the Milky Way Galaxy since the Horus Heresy. The Forces of Chaos succeeded at last in overwhelming the defences of Cadia when Abaddon unleashes the shattered remains of a Blackstone Fortress known as the Will of Eternity as an artificial meteor to destroy the Cadian Pylons and devastate the Fortress World's valiant Imperial defenders.
Time of Outbreaks, M41-M42
Note: All dates from this point forward are provisional due to errors in the Imperial Calendar, meaning these events could actually have occurred at any time from the early 41st Millennium to the early 42nd Millennium.
- Galactic Epidemic (ca. 999.M41-Unknown Date.M42) - In the wake of Cadia's fall during the 13th Black Crusade, the Great Rift thunders into being, reality bursting open like the stitches of a weeping wound to spill Warp-stuff into the galaxy. Plague Fleets strike all across the Imperium, spilling from the roiling Warp Storms of the Noctis Aterna to spread misery and decay.
- The Plague Wars (Unknown Date.M42-ca. 111.M42) - As the Blackness settles across great swathes of the Imperium, Chaos Cult activity and recidivist uprisings lead to the daemonic infestation of several prosperous star systems to the galactic north of Ultramar. Under the influence of Mortarion, these worlds fall entirely into Nurgle's grasp and become the "Scourge Stars," a feculent fortress for the servants of the Plague Father within realspace. It is from these suppurating staging posts that Mortarion will launch his campaigns into Ultramar in what will become known as the "Plague Wars."
- Rain of Filth (Unknown Date.M42) - During the siege of Godorian -- a world unlucky enough to be within light years of the Scourge Stars -- squadrons of Plagueburst Crawlers lob their shells in high parabolas. The diseased munitions slam down on manufactorum stack-vents and spill their filth in the Godorian labour furnaces to create giant, toxic plague censers. The resultant smog clouds drive the Imperial defenders into the open, easy prey for the guns of the Death Guard.
- Warzone Ultramar (Unknown Date.M42) - Mortarion's long-awaited invasion of Ultramar begins, initiating the Plague Wars. Sepsis cohorts of every Plague Company join the fight, with the 2nd, 3rd and 7th Plague Companies deploying in almost their entirety. Marching alongside daemon Tallybands, corrupted Renegade Knights, Traitor Titan Legions and countless warbands of Renegades, Chaos Cultists and turncoat Astra Militarum, the grotesque armies of Nurgle force the beleaguered defenders of Ultramar back step by bloody step.
- Unholy Endurance (Unknown Date.M42) - WAAAGH! Badsmak overruns a score of worlds to the galactic west of the Scourge Stars, forcing Mortarion to deploy numerous vectoriums to counter its wrath. During the campaign's pivotal battle on Krug's World, Warlord Badsmak himself leads a headlong charge against the outnumbered Death Guard. Death Guard Lord Fulgous the Bloated orders an immediate advance into the teeth of the Greenskin assault, calling down Plagueburst Crawler fire upon his own position. Weathering the pounding ordnance through a mixture of resilience and sorcery, the Death Guard draw the Orks into an explosive meat grinder. Plaguespitters dissolve wave after wave of the enemy hordes. Noxious Blightbringers toll their tocsins of misery again and again, driving the Greenskin Weirdboyz insane and spreading despair through the ranks. Finally, Badsmak and his surviving Boyz flee in abject terror, only to be annihilated by the Plague Marines' pursuing fire.
- Gifts of Nurgle (Unknown Date.M42) - On the Industrial World of Drogensul, several vectoriums of the 1st Plague Company meet stiff resistance from Imperial defenders. Death Guard drop ships make repeated passes over the industrial fortress-factories, dropping spiked iron cubes the size of hab units that crash down in the streets and manufactoria. Disease radiates from these rusting monoliths, and the Imperial defenders waste no time in setting charges to destroy them. The true horror of the Death Guard plan is revealed when the charges blow, rupturing the cubes and allowing the tightly-packed Poxwalkers inside to spill from the wreckage. Within solar days the Walking Pox is rife throughout the fortress-factories of Drogensul. Only then do the Plague Marines of the 1st Plague Company return to finish the fight.
- In the Maw of the Storm (Unknown Date.M42) - As Warp Storm Fomori engulfs the world of Danasar, Typhus duels -- and humbles -- Huron Blackheart atop the ruins of the Endless Spire. He leaves the Tyrant of Badab alive as an abject lesson not just in Nurgle's might, but also of his generosity.
- The Siege of Bellisos (Unknown Date.M42) - Much of the 3rd Plague Company find themselves besieged within the ruined husk of Hive Arkturon on the world of Bellisos. Led by Inquisitors of the Ordo Malleus, a huge force of Astra Militarum, Adepta Sororitas and Imperial Knights hammer the Death Guard positions day and night. Yet between the Death Guard's resilience and the screaming volleys of Plagueburst Mortar shells that are fired in return, it is the besiegers who find their forces ground down, and their warriors riddled with sickness. By the time the Death Guard launch their breakout assault, few of the attackers have the strength remaining to deny them victory.
- Battle of Bosphodia (Unknown Date.M42) - Vectoriums of the 5th and 6th Plague Companies engage in a naval battle with Craftworld Saim-Hann and its fleet around the moons of Bosphodia. Before they are driven off, the Death Guard successfully board the Craftworld and spread their corruption through the territory of Wild Riders clan Sylthach. In desperation, Saim-Hann's Seer Council orders Ghost Warriors to cut that part of the world-ship away with weapons fire. So devastating is the despair felt in that moment by the Aeldari that it conjures Nurgle daemons into the Waystones of the surviving Sylthach clan members, possessing them and transforming them into aberrant, insectile half-breeds. Soon enough, tales of spiteful, Chaos-tainted Aeldari Corsairs are prevalent throughout the Paragos Sub-sector and beyond.
- The Greyfax Gambit (Unknown Date.M42) - Having noted the fanatical obsession the Death Guard hold for the number seven, Inquisitor Katarinya Greyfax applies her suspicions to the battle for the Shrine World of Dortwyr. Launching their final assault on the seventh hour of the seventh day, the Death Guard pursue a baiting force of White Scars Primaris Astartes straight into the firing lines of seven Deathstrike Missile Launchers. The resultant rad-conflagration obliterates the Death Guard presence upon Dortwyr entirely.
- The Pristine Rotting (Unknown Date.M42) - After enduring solar months of filth and indignity in battle against the Putrid Choir, the Astra Militarum's 14th Volpone Bluebloods can take no more, and beg Nurgle to spare them from the corruption. The Plague God answers, rendering them forever gleaming and pristine, except for every seventh soldier amongst them. These unfortunates endure all the disease and pestilence their comrades should have, bloating into dirt-smeared, infectious spawn whose forlorn wails and wretched stench drives the rest of the regiment mad with guilt and horror. The Bluebloods turn their guns on their former comrades before throwing in their lot with their Death Guard tormentors.
Time of Rotting, M41-M42
Note: All dates from this point forward are provisional due to errors in the Imperial Calendar, meaning these events could actually have occurred at any time from the early 41st Millennium to the early 42nd Millennium.
- War in the Rift (Unknown Date.M42) - During the War in the Rift between the forces of the rival Chaos Gods, Mortarion decapitates the seven champions of Lybria, turning their skulls into virulent Death's Heads Blight Grenades. These he uses to banish the great Bloodthirster Ka'Bandha back into the Warp, sending him hence with a mocking gift of despoiled skulls no longer fit for Khorne's throne.
- The Rusthounds Arrive (Unknown Date.M42) - Amidst the ruins of Chambakh, Knights of House Krast battle the mechanised infantry of the Pallid Hand. Shrugging off salvo after salvo of Blight Launcher rounds, the Knights trample the Death Guard and claim victory. Yet in doing so their mechanical steeds are infected with Ferric Blight. What emerges from that festering war zone is a warband of Renegade Knights rusted through in body and soul, limbs shrieking and seized, Thrones Mechanicum tainted beyond recovery. Renaming themselves the Rusthounds, the Knights set off on the hunt for their former allies' souls.
- Return of the Eisenstein (Unknown Date.M42) - A battered Imperial warship impossibly identified as the long-destroyed, legendary Death Guard vessel Eisenstein is sighted beyond the third moon of Lorn's Landing, glowing with a lambent hue before vanishing without trace. Just solar days later, the Death Guard descend upon Lorn's Landing with Mortarion at its head. Inquisitorial savants note with alarm that this is the sixth such manifestation to herald the coming of the Death Lord himself. They fear what may transpire upon the seventh.
- Invasion of Medusa (Unknown Date.M42) - Alongside warbands of The Cleaved, The Purge and several other Nurglite Renegade forces, Typhus leads the Death Guard's 1st Plague Company in a shocking raid against the Iron Hands' Chapter Planet, Medusa. The Iron Hands clans drive off their attackers, but not before terrible damage is done, leaving regions of the planet as cursed quarantine zones.
- Siege of Nebbus (Unknown Date.M42) - As the Death Guard's siege of the Imperial Hive World of Nebbus reaches it seventh standard year, Mortarion's Death Guard Sorcerers summon an ancient evil to aid them. The strange Great Unclean One known as Rotigus joins the fight, bringing with him his appalling aura of infernal fecundity. Protein vats in the hives overflow as the flesh-broth within them grows at an unstoppable pace, burying entire levels under flabby drifts of bloated meat. Vermin of every sort enter frenzied cycles of birth and death, the Imperial defenders finding themselves overwhelmed by tides of sump-rats, infestations of grizzleworms and million-strong swarms of ravenous ripper jacks. Worst of all is the deluge of Nurgle, an endless storm of putrid filth-water that seethes with infectious, bacterial life. Soon enough Nebbus' arid plains become quagmires, then stinking oceans that rise higher and higher. The corpse-choked hive cities flood from the roots upward, their last garrisons fleeing ever higher in search of a salvation that does not exist. Blessed beyond endurance by the plentiful generosity of Rotigus and his daemons, methodically cut to pieces by the thundering guns of the Death Guard, it is almost a mercy when the last of Nebbus' defenders meet their grisly deaths.
- Tainting of the Minotaurs' Gene-Seed (Unknown Date.M42) - A sepsis cohort of the 7th Plague Company strikes at the fortress-monastery of the Minotaurs Chapter. Their attack is driven off, but celebration turns to despair upon the discovery that Mortarion's sons have tainted the Chapter's gene-seed stocks beyond redemption. So begins a desperate quest for survival, a crusade across the stars to reach Terra and access purified gene-seed reserves before the Chapter wastes away.
- Battle of Yultah (Unknown Date.M42) - During the Battle of Yultah, Mortarion and his Deathshroud stand unaided in the breach against an entire Necron legion. Death Guard reinforcements fight their way frantically to their lord's side, fearing the worst. Instead they find Mortarion and his last surviving Deathshroud warrior, wounded but triumphant and surrounded by sparking, dematerialising heaps of foes.
- The Great Brewing (Unknown Date.M42) - Deep within the Imperium Nihilus, the Poisoned Chalice invade the medicae world of Pelucil. They seek to use the planet's macro-alembic complexes to brew the ultimate plague in Nurgle's name.
- Battle of Hollowfall (Unknown Date.M42) - The Pallid Hand are ambushed by overwhelming Necron forces from the Novokh Dynasty amidst the ruins of Hollowfall. During a fighting retreat, Mortarion's sons infect a number of Necron Warriors with Ferric Blight. Phasing out, the undying android warriors bear the deadly contagion back to the stasis crypts of their Tomb World, beginning an epidemic of catastrophic proportions.
- Battle of Hesp (Unknown Date.M42) - Vectoriums of the 4th and 7th Plague Companies engage the Tyranids of Hive Fleet Lotan amidst the steaming jungles of Hesp. When the swarms deploy Toxicrenes and Venomthropes to poison the environment, the Death Guard respond with plague spells, Virus Bombs and daemonic diseases. With neither side willing to back down, the atmosphere of Hesp becomes ever more toxic until the jungles, and even the warring armies, are reduced to a gory, bubbling soup. The first Tyranid Hive Ship to taste this poisoned slurry recoils, its proboscis melting, and is bombarded into oblivion by the rest of its fleet. The Jungle World of Hesp is left as an endless sea of toxic slime, too virulent for even the Hive Fleets to devour.
- Assault on the Writhing God (Unknown Date.M42) - The Space Hulk Writhing God is chosen by the 6th Plague Company, "The Ferrymen," to join Mortarion's Plague Fleets. The Hulk is infested with warring Genestealers and Orks, and so squads of Blightlord Terminators teleport to key points aboard, bearing rune-encrusted plague bombs. Fighting their way through tides of foes, the Chaos Terminators prime their bombs before the survivors teleport back to safety. Thudding detonations shake the Writhing God, disgorging Nurgle's Rot, Greenlung Pox and the Squamous Scourge amidst its warring passengers. Seven solar days later the Death Guard return, wading through deep drifts of rotted corpses to claim the depopulated Space Hulk.
- Battle of Dysactis (Unknown Date.M42) - During the fyredust season on Dysactis, a vast Death Guard force advances through the pyroclastic storm fronts in search of the Temple of Ascension. They are met amidst the crackling maelstrom by an enormous force of Iron Warriors, supported by corrupt God-machines from the Legio Abhorrax. Continent-shattering battle ensues. Hordes of daemons are summoned from the Beyond to join the fight. Beneath the gaze of the Cyclonead Statues, Mortarion and his fellow Daemon Primarch Perturabo themselves engage in a spectacular duel that lasts for seven solar hours. It is a battle reminiscent of the incredible conflicts of the Horus Heresy, and Perturabo's sons cause terrible damage to the Death Guard force. Yet the longer the fighting rages, the more the contagions and metaliphage poxes of the Death Guard spread through the Iron Warrior ranks. Ancient Heretics sicken and collapse. Malevolent war engines seize with rust and shudder, sparking, to a halt. Machine Spirits go mad with revulsion and pain, and as the powers of entropy and decay run rampant, the battle swings in Mortarion's favour. With his forces in tatters and many of his precious war engines crippled beyond repair, even bitter Perturabo is finally forced to concede defeat. Falling back to pre-prepared defence lines, he detonates a series of explosive trenches amidst the raging storms and disengages in the ensuing mayhem. Badly mauled but triumphant, Mortarion and his Death Guard lay claim to the heathen temple they fought so hard for, and the ancient secrets that lay at its heart.
- Lynoxis Infested (Unknown Date.M42) - Leading his favoured vectoriums of the 7th Plague Company, Mortarion attacks Lynoxis, an Imperial Ocean World and the Chapter Planet of the Golden Paladins. Timing his attack to coincide with an auspicious sevenfold eclipse, Mortarion has his Biologus Putrifiers and Foul Blightspawn poison the planet's seas. Amidst the resultant apocalypse of disease and filth-encrusted horror, the Death Lord leads his sons to absolute victory, opening up a new outbreak within the shadows of the Imperium Nihilus and spawning a dozen plague-ridden war zones in Imperial space.
Before they were reunited with their Primarch, the Dusk Raiders conformed very closely to the standard raiment of arms and organisational patterns laid out for the early Space Marine Legions by the Imperial Officio Militaris. At its most fundamental level the Dusk Raiders Legion was organised around the principle of equipping its individual Space Marines as well as possible, so that they could endure and prevail against any foe encountered and operate for extended periods without resupply or support if necessary.
This dogma was the cornerstone of the XIVth Legion's way of war, and was built upon the foundations of independence and surety with which the Dusk Raiders had always fought. The Dusk Raiders are noted in the Imperial records of this period as maintaining a well-rounded capacity for unleashing multiple modes of warfare, although with some bias towards heavy assault formations and attritional engagements, as evidenced by the particular use of close-ranged weaponry within the Legion.
The Dusk Raiders Legion relied upon its infantry to provide its strategic strength, with the bulk of tactical fire support coming from heavily armed support squads, and later with considerable numbers of Terminators and Dreadnoughts providing reinforcement and an assault spearhead where needed.
Once Mortarion became the master of the XIVth Legion the Death Guard changed dramatically, including its arts of warfare. Mortarion was at his heart an infantryman, and in his Death Guard he saw the chance to perfect the principle of the utilitarian warrior on foot who could go anywhere, fight on any ground and destroy any enemy through resilience, resolve and implacable aggression.
As part of this doctrine, the Death Guard's squad formations were largely not static as in most Space Marine Legions of the time, but were formed, reformed and ordered as needed and as the given tactical situation required. To this end, a Death Guard Legionary was trained to be equally adept at any infantry role he might be called upon to perform on the battlefield rather than fighting at all times in a particular specialised role.
In this way, a Death Guard Astartes would act as a Tactical Marine in one battle, a heavy weapons fire support specialist in another and so on, with only Techmarines and other highly specialised occupations remaining wholly dedicated to a single tactical role.
The Death Guard was organised around the principles established by the Dusk Raiders and built upon the ways they had always fought. Bolter, Melta and Flamer became the Death Guard's trinity of weapons around which their wargear was based, keeping supply needs to a minimum. Other types of ranged weapons were deployed sparingly only as the tactical situation or nature of the enemy demanded.
Each Death Guard also carried a close combat blade as well, which included broad trench daggers, Warscythes and the heavy slashing Kukra native to Barbarus. Forged of dense black ceramsteel, these brutal and efficient weapons soon became the hallmark of the Astartes of the XIVth Legion.
This reliance on simple but effective tools of war was an outward manifestation of the cardinal belief held by the Legion that the Space Marine himself was the greatest of all weapons at the Imperium's disposal, a tireless engine of war before which any enemy would eventually succumb.
The Death Guard continued to rely throughout the Great Crusade almost exclusively on its infantry to provide its strategic strength, with the bulk of tactical support firepower coming from heavily armed support squads, and later from the Legion's considerable numbers of Terminators and Dreadnoughts, which provided reinforcement and assault spearheads where needed.
This focus on heavy infantry formations was also one of the reasons the Death Guard Legion developed a particularly admirable record in fighting to clear Space Hulks of alien infestation and for their ability to destroy fortifications and citadels from within.
While the Death Guard did utilise field armour, support vehicles and transports (as Mortarion would not allow his forces to be circumvented, cut-off or left wanting for their lack), these were not given any primacy in the Legion's tactical doctrine. The only exception to this were dedicated siege units such as the Vindicator which was fielded in disproportionately high numbers by the Legion, alongside squadrons of Fellblade super-heavy tanks and Land Raider Spartans in mass warfare.
It was notable in hindsight, and would prove to be a telling factor on Istvaan III, that a proportionately high number of the Death Guard Legion's war machine crews were still of Terran blood by the time of the Horus Heresy, while the heaviest infantry strike units, particularly the Legion's sizable core of Terminator Armour-equipped shock troops, were of Barbarus stock.
Unlike some of the Space Marine Legions whose operations were often diffused across separate commands, taskforces and campaigns spread across the galaxy during the Great Crusade, the Death Guard were accustomed to fight as a single, united force. As such, when the XIVth Legion came to the Istvaan System at the start of the Heresy with almost its entire strength, the most accurate accounts of the time claim that the Death Guard maintained approximately 95,000 Space Marines, 70 capital ships and perhaps three times that number of smaller Escort and assault craft.
With the conclusion of the bitter fighting on Istvaan III, it is estimated Mortarion's Legion had been reduced by well over 25,000 casualties, counting both the stubborn Terran Loyalists, betrayed to their deaths in the ash-mantled ruins of Istvaan III, and Mortarion's sons of Barbarus whose lives had been spent to purchase their demise.
It is believed that protracted fighting during the Istvaan III Atrocity had exacted a heavy toll on the Death Guard's armoured divisions, many of which had been amongst the suspected Loyalists within the Legion. Though it is believed many vehicles had been recovered from the planet, very little time had been available to render them fully battle-worthy again.
However, the fighting that was to occur during the Drop Site Massacre engagement was to suit the Death Guard Legion well, with its strong emphasis and preference on attritional warfare and close order infantry tactics.
Evidence suggests that a large core of Death Guard Legionaries deployed to one flank of the Urgall fortress-line, into a network of trenches, bunkers and slip-tunnels swiftly, but expertly, prepared or augmented by the Legion. This provided them both with deep protection from bombardment and hid their numbers.
Legion Command Hierarchy
When the newfound Primarch Mortarion was given command of the XIVth Legion, he remade it as a single instrument of his will. Of all the Space Marine Legions, it was said of the Death Guard that they were but one entity with a single purpose and one body.
The XIVth Legion was re-ordered into seven "Great Companies" of considerably larger size than the standard Astartes Legion organisational structures of the Great Crusade era mandated. Obedience and order in the ranks of the Death Guard was absolute and an unbroken chain-of-command ran like blood in the Legion's veins.
Legionaries were extensions of their sergeant's will, sergeants their captain's, and captains their commander's, while collectively the Astartes of the Death Guard were all instruments of Mortarion, body and soul.
Few other ranks or divisions of formal organisation existed in the XIVth Legion, except in very specialised, often technical roles. Each member of the Legion knew his place and the seniority and tasks of those around them without recourse to excessive heraldry and symbol.
While many Legions had the tradition of giving the honorific of "First Captain" to the commanding officer of the elite 1st Great Company, the Death Guard also held two more privileged titles to be bestowed upon the commanders of the 2nd and 7th Great Companies, respectively.
Thus, although they held no actual seniority over one another, the Captain of the 2nd Great Company could carry the rank of "Commander" if he so wished, just as the Captain of the 7th Great Company was known as the "Battle-Captain."
All Death Guard Astartes conformed to Mortarion's decree without rancour or dissent, and rivalries and internal strife were observed by outsiders to be few, particularly in comparison to more notably fractious Legions such as the Night Lords or Space Wolves.
When an officer died in battle, his successor stepped into his place swiftly and decisively without need for orders or discussion, and so the Legion's chain-of-command was seamless even in the face of the heaviest losses, contributing to the Death Guard's reputation for endurance in war.
Specialised Ranks and Formations
- Deathshroud - The Deathshroud was an elite cadre of specially selected Battle-Brothers from the XIVth Legion who served as Primarch Mortarion's mute bodyguards during the Great Crusade. Great secrecy surrounded this elite cadre, whose numbers were chosen from amongst the standard ranks of the Death Guard Legion from Astartes who had been singled out and personally selected by their Primarch for their bravery and valour. Once chosen, the selected Battle-Brother would give up his former life as a common rank-and-file Astartes and swear binding oaths of secrecy. A member of the Deathshroud would be listed as killed in action to allay any suspicions as to their true identity, and he would forever conceal his face by always wearing an enclosed helmet, mask or hood. The identity of each member of the Deathshroud was known only to Mortarion himself, even in the event of their death. The Deathshroud wore Artificer-crafted Terminator Armour of the highest quality, presenting a foreboding appearance with their barrel-chested appearance and like their Primarch, wielding large scythes called Manreapers. It was the Deathshroud's sacred duty to never stray more than forty-nine paces from Mortarion, with two Deathshroud warriors customarily escorting the Primarch at any given time, though there may have been more hidden in the shadows. These stoic warriors' presence was quite intimidating, as they stood uniformly at attention at all times, as still as statues. But in battle the Deathshroud would prove equally frightening, for whatever the odds, they always moved inexorably towards their target, almost as if they were automated killing machines.
- Grave Warden Terminator Squad - Originally used as an informal name for the variously armed battalions of Death Guard Terminators of Calas Typhon's company carried into battle aboard the unique Battleship Terminus Est, the term "Grave Wardens" also eventually became synonymous both within the Death Guard Legion and beyond it, specifically for the alchemical weapon-equipped Terminators unique to the Death Guard. Alone among the Legiones Astartes, the Death Guard made free and frequent use of alchemical weapons such as the crawling horror of Phosphex, inimically lethal Cullgene gas and flesh-eating Vasgotox fluid as a matter of course, and outfitted specialised units in modified patterns of Tactical Dreadnought Armour to disperse it accordingly. Where the Grave Warden Terminator Squads walked, they brought lingering, ugly death to whatever and whoever crossed their paths.
- Destroyer Squads - Considered dishonourable by some of the Space Marine Legions who made little use of them or eschewed them altogether, Destroyers were equipped with and expert in the use of otherwise proscribed and forbidden weaponry. Alongside certain factions of the ancient Mechanicum, only Destroyer cadres had the license to use these weapons in the forces of the Imperium by the Emperor's command. Rad-weapons, bio-alchem munitions and the burning horror of Phosphex were a necessary evil, although the effectiveness of their relic-weapons in cracking especially difficult enemy defences could not be denied.
Attrition rates within the Death Guard Legion on active service were frighteningly high despite their legendary resilience. Indeed for many years of the Great Crusade only the World Eaters and Iron Warriors Legions were on occasion recorded to have spent more lives proportionately to their strength in pursuit of the Imperium's conquest.
Barbarus itself in a short span of Terran years became little more than a factory to produce new recruits for the Death Guard Legion, and intake from other sources of recruitment to which the Legion had title dwindled to a mere handful, unless the pressure of combat losses proved too great.
Mortarion's resistance to the use of bloodstock other than that of Barbarus wavered only because of the need to keep his Legion's strength battleworthy according to his own high standards.
Recruitment solely from Barbarus was, however, aided by the high suitability of the planet's feral population for the Astartes conversion process.
Following the Death Guard's corruption and Mortarion's ascension to daemonhood after the Legion took refuge in the Eye of Terror following the Siege of Terra, the Legion began to splinter into smaller forces called warbands, although the Plague Marines still endeavour to organise themselves into multiples of seven, Nurgle's sacred number.
However, with Mortarion's return to active leadership of the Death Guard following the opening of the Great Rift in 999.M41, a more formal Legion organisation reemerged. Now, in the Era Indomitus, the Death Guard are amongst the most ordered and coherent of all the surviving Traitor Legions.
Mortarion, ever a traditionalist, still bases their structure upon the vast Space Marine Legions that fought during the Heresy, though the new formations still revolve around the sacred number of seven.
Each of the so-called seven "Plague Companies" that comprise the post-Heresy Death Guard thus numbers thousands of warriors, utterly dwarfing their equivalent formations amongst the Loyalist Space Marine Chapters of the late 41st Millennium. A fully detailed diagram of the Death Guard Legion's full post-Heresy organisational scheme can be seen above.
In general, each Plague Company is further divided into seven smaller units called "sepsis cohorts." Sepsis cohorts number around seven hundred Plague Marines, supported by infected auxiliaries, armour formations and Daemon Engine packs.
Each sepsis cohort is divided into two "maladictums," both a formidable fighting force in its own right. The Lord Commander of each Plague Company, usually a Death Guard Lord or Daemon Prince, is the sacred host of one of Nurgle's vilest diseases, and the seven sepsis cohorts that serve him are its most favoured vessels.
In turn, each maladictum is divided into seven "colonies". Colonies number seven squads of seven Traitor Legionaries led by a powerful Death Guard Lord and accompanied by lesser Chaos Champions of Nurgle, armoured vehicles, attendant daemons and Daemon Engines. The 1st Colony of each sepsis cohort's maladictums often consists solely of Blightlord Terminators, much like a standard Space Marine Chapter's elite 1st Company.
For all its theoretical cohesion, in reality the Death Guard Legion is still broken up like most Chaos Space Marine formations across thousands of galactic war zones, often at the whims of Chaos Lords, Chaos Champions and the like. These warbands vary hugely in size and composition, but all are known as "vectoriums."
Those that fight together for any length of time will be named by their leader, and will often adopt -- or simply manifest -- a unifying colour scheme. Most vectoriums are drawn from the maladictums or colonies of the same Plague Company, but some can be more disparate still.
Typical Death Guard vectorium warbands include so-called "Plague Colonies" comprised of standard Plague Marines, "Destroyer Colonies" of similar troops equipped with Alchemical Weapons, and "Reaper Colonies" of squads mounted in armoured transport vehicles.
Order of Battle
|1st Plague Company||2nd Plague Company||3rd Plague Company|
|4th Plague Company||5th Plague Company||6th Plague Company||7th Plague Company|
- 1st Plague Company, "The Harbingers" - The 1st Plague Company is ruled over by Typhus, and its forces are often called the Harbingers. Its ranks are infested with hundreds of different strains of the Zombie Plague, including Shamblerot, the Groaning and Biter's Pox.
- 2nd Plague Company, "The Ferric Blight" - The 2nd Plague Company favours mechanised assaults, and boasts huge formations of lumbering battle tanks. Its warriors bear the Ferric Blight, which speckles their armour and vehicles with crawling rust that can swiftly infest the foe.
- 3rd Plague Company, "Mortarion's Anvil" - The warriors of the 3rd Plague Company excel at digging in and letting their foes dash themselves apart against their defences. They carry the Gloaming Bloat, a plague of fever sweats that slicks their armour and causes them to speak in wet gurgles. The 3rd Plague Company is also known for having Noxious Blightbringers prevalent amongst their ranks. Its commanding Death Guard Lord Gothax the Morose is renowned for ensuring that seven Blightbringers accompany him as a trudging retinue at all times. In the gruelling sieges and meat grinders favoured by the 3rd Plague Company, the entropic shock waves of their tocsins of misery are invaluable.
- 4th Plague Company - The 4th Plague Company is ruled over by the gestalt Daemon known as the Eater of Lives. Its Legionaries carry the Eater Plague, also called Drizzleflesh, Pockchewer and the Endless Gift, and its inhuman master favours Death Guard Sorcerers and summonings of other Nurglite daemons.
- 5th Plague Company, "The Poxmongers" - The 5th Plague Company makes great use of diseased Daemon Engines. Its forces carry the Sanguous Flux, which causes endless, half-clotted bleeding and leaves foul red-black trails behind them wherever they go.
- 6th Plague Company, "Ferrymen" or "Brethren of the Fly" - The 6th Plague Company garrisons the Plague Fleets, and acquires new starships for their armadas. It boasts large numbers of Blightlord Terminators riddled with the parasite known as the Droning.
- 7th Plague Company, "Mortarion's Chosen Sons" - Those of the 7th Plague Company have the honour of being Mortarion's Chosen Sons. They are plague brewers and dark alchemists, and are blessed by Nurgle with the Crawling Pustulance, also known as Boilblight, Lumpen Splatter or Nurgle's Fruit.
|1st Sepsis Cohort||2nd Sepsis Cohort||3rd Sepsis Cohort|
|4th Sepsis Cohort||5th Sepsis Cohort||6th Sepsis Cohort||7th Sepsis Cohort|

Specialised Ranks and Formations
- Death Guard Lord - Death Guard Lords are the Chaos Lords who hold positions of command throughout the Traitor Legion's ranks. Through mighty deeds of destruction, corruption and endurance do they prove their right to rule. As with all aspects of the Death Guard, Mortarion has retained an iron grip upon the doctrines and dispositions of his champions. He expects even his most gifted sons to choose the path that best suits their talents, and then to cleave to it. In this way Mortarion ensures that even as the Lords of the Death Guard win the favour of Nurgle and progress along the path to glory, they still integrate with the pragmatic, infantry-based tactics of their warriors. In accordance with this philosophy, Mortarion created the Mantles of Corruption, which have become redolent with power and menace over the millennia. The strategies and armaments of each are as instantly recognisable as the revolting symptoms of Nurgle's greatest plagues:
- Lord of Contagion - The most aggressive and belligerent Lords of the Death Guard take up the Mantle of Contagion. Lords of Contagion lumber into battle in filth-smeared Cataphractii Terminator armour, wielding either snarl-toothed axes taller than a man or two-handed scythes that sweep aside the foe. They tend towards direct strategies with little in the way of cunning or subtlety, and are pugnacious commanders, supremely confident in their followers' ability to absorb the worst the enemy can throw at them and still prevail. They embody the swift-spreading plague that tears through a crowd, killing indiscriminately and leaving mounds of bodies in its wake.
- Lord of Poxes - Lords of Poxes favour the spreading of airborne miasmas and the merciless, attritional erosion of the enemy.
- Lords of Virulence - Lords of Virulence are masters of massed bombardment, hammering their enemies with heavy firepower and decimating their ranks in the manner of a lethal infection laying its victim low.
- Deathshroud - Swollen with unnatural power, the Deathshroud tower over their enemies. Rusted gauntlets and squirming tentacles clutch huge battle scythes known as manreapers, cursed weapons that slice heads from shoulders and limbs from torsos with every swing. Clouds of plague flies boil around the Deathshroud, while vile smog spills from vents in their armour to choke and blind their foes. The warriors of the Deathshroud are sublimely skilled, whirling and striking with a speed that belies their massive, distended frames. Yet it is not merely their abilities in battle that make them so feared. The Deathshroud are the handpicked champions of Mortarion, his dark emissaries, and wherever they go they bear the authority of their gene-sire with them.
- Blightlord Terminators - Blightlord Terminators are relentless and unstoppable, elite Death Guard warriors bound forever to mutated suits of Cataphractii Armour. They stalk forward with guns blazing, mercilessly mowing down rank after rank of the enemy. Combi-weapons, plague spewers and blight launchers add to the fusillade, reducing infantry and vehicles to slop. Combining the protective powers of Cataphractii war plate with the diseased resilience bestowed by Nurgle's gifts, Blightlord Terminators are terrifyingly hard to kill. They take great pride in this fact, advancing contemptuously into the teeth of the fiercest firestorms, mocking their enemies' attempts to lay them low.
- Noxious Blightbringer - Heralds of pestilence and misery, Noxious Blightbringers pace solemnly before the Death Guard advance. They proclaim the arrival of Mortarion's sons through the tolling of their rusted tocsins of misery, hell-forged bells of massive size whose peals ring through both reality and the warp. The primary role of Noxious Blightbringers is to sow dismay and weakness amidst the enemy ranks. The dissonance of their chiming bells sends waves of entropy rolling across the battlefield to batter not only the enemy's physical senses, but their souls. The blessings of Nurgle manifest wherever the tocsins' waves hit home, each thunderous toll wearing the foe down a little more and spreading sickness and corruption.
- Death Guard Sorcerer - Harnessing the energies of the warp, the Sorcerers of the Death Guard call down the repugnant blessings of Nurgle upon ally and enemy alike. Withering plagues weaken their foes, causing bones to rot and splinter, and muscle to waste away to red-brown sludge. Vile conjurations conceal the Death Guard from their enemies amidst storms of hairy black flies, or else swell their bloated bodies with unnatural might and fecund resilience. Daemonic blights are summoned forth that burn through the enemy ranks like wildfire, while the battlefield itself turns to rot and ruin, fortifications crumbling as empyric parasites burrow through their foundations.
- Malignant Plaguecaster - Potent Death Guard Sorcerers, these vile psykers are Warp-rotted from their pallid, flyblown skin to their ever-churning innards. They have bargained away what remained of their souls in exchange for Nurgle's blessings, and been gifted with the ability to channel the malaise of the Plague God's realm. The bloated bodies of Malignant Plaguecasters have become living conduits for the Garden of Nurgle's toxic miasmas.
- Tallyman - Tallymen are the preachers of the sevenfold doctrine of the number seven, the unholy number of Nurgle, the integer infectum, the digit of disease. Part priests, part demagogues, part metaphysical scribes and quartermasters, these festering zealots stride to battle festooned with the trappings of their strange craft. The Tallymen count woes. They count shells expended, wounds inflicted, foes that flee screaming into the gloom. They count the flies in the air and the number of the slain, victories achieved and defeats suffered. Always they tally the unholy seven, and in so doing they invoke Nurgle's boon. Nurgle's faithful are empowered and inspired by the Tallyman's count. As his voice echoes in their ears, so empyric power seeps into their souls.
- Biologus Putrifier - Driven by an obsessive desire to test their plague-batches to perfection, Biologus Putrifiers take a very active role in spreading disease upon the field of battle. From their backs dangle racks of blight grenades, churning with the latest strains of noxious plagues to issue from the disease factories. Death’s heads drip foetid slime. Biologus Putrifiers bear a unique mutation: lidless, milky eyes that grow like cysts concealed beneath their flesh. Known as occulobes, the gaze of these foul orbs can penetrate armour, flesh and bone to perceive every nuance of an infection's spread through a living body.
- Plague Surgeon - Sinister, hooded figures, Plague Surgeons drift through the mayhem of battle like ghoulish spectres of death. They were once Death Guard Apothecaries who brought healing to those who could be saved, and absolution to those who could not. Damnation transformed their order, rendering them the dark antithesis of what they once were. Like proud fathers, the Plague Surgeons spare no effort in tending to all of Nurgle's children. Their bodies are incubators for every form of parasite and phage, their flesh and blood offered willingly as living nurseries for these ghastly offspring. As a result, the very touch of a Plague Surgeon is virulently infectious, while every breath they exhale teems with spores and daemon motes. The miasma that seeps from their censers and the filth that drips from their weapons and surgical instruments only adds to this effect. Any foe foolish enough to engage a Plague Surgeon in combat will soon be crawling with empyric disease.
- Plague Marines - Bloated with festering corruption, Plague Marines form the mainstay of the Death Guard, and unlike many Traitor Legions their numbers have only swollen as the millennia have passed. Sworn to Nurgle's service, Plague Marines have disgusting, rotted bodies that stink of decay. The putrescent slime that oozes from their sores corrodes armour and boils away skin, yet despite their horrific disfigurements they are fearsome warriors indeed. Their rotting brains are inured to the agony of bodily corruption, making them all but immune to the pain or debilitation caused by battle wounds.
- Foul Blightspawn - Foul Blightspawn rise from amidst the Plague Marine ranks, typically those warriors who feel joy in watching their victims suffer in the grip of Nurgle's plagues. Malignant cruelty festers in their souls, manifesting itself in ever more grotesque physical degeneration. Their flesh bulges with putrid flab until it becomes translucent. Their eyes dribble from their sockets as black slime, leaving the Blightspawn to 'see' in shades of warp energy. Their mouths twist into fanged, puckered spouts, and a wretched stench seeps from their pores, so foul that it causes even Plague Marines to balk. All the while, forbidden secrets of Nurgle's plaguecraft blossom in the Blightspawns' minds, compelling them toward obsessive alchemy and the joyous brewing of noxious disease.
- Chaos Cultists - On every world beset by disease or despair, cults of Nurgle arise. Worshippers seek escape from the pain and misery of sickness, and take perverse pride in their diseases and deformities. Led by bubo-ridden magisters and prophets of plague, the cults taint water supplies, destroy food stores, release weaponised viruses and stockpile arms and equipment for their inevitable uprising. Many Nurgle cults are rooted out and burned by the Imperial authorities. Yet others grow and multiply until, when the Death Guard arrive to despoil their world, they are ready to rise up and aid their new masters. Other cults are recruited from the tribes of the Plague Planet, or founded by the Death Guard themselves from the slaves they claim in their wars against other Chaos powers. Whatever their provenance, Cultists of Nurgle assail the foe in huge numbers. Their diseased bodies are inured to pain, their fevered minds so deranged that they charge screaming into battle without fear.
- Daemon Prince - Daemon Princes of Nurgle are lumbering abominations whose unnatural resilience renders them nigh invulnerable. They are swollen with power, their groaning, corroded armour burst open by the bulging flesh within. Layers of rotting flab and putrid innards spill from their necrotic skin, insulating them against small arms fire, while notions of pain or weakness are long forgotten. Even direct hits from tank busting weaponry do little to slow these immortal horrors, for though they may punch through the Daemon Prince's body, this will achieve little but spray infected pus and slime across friend and foe alike. Eventually their minds snap, their bodies writhe and twist with the mutagenic power of the warp, and their last vestiges of humanity vanish amidst a seething mass of wet muscle, lashing tentacles and gnashing maws. Such degenerate beasts are viewed by the Death Guard as little more than cannon fodder, walking barricades of groaning flesh that are herded into battle to soak up incoming fire and disrupt the enemy lines. For all this, the damage rampaging Chaos Spawn can inflict before they fall is hideous.
- Plaguebearers - Plaguebearers are the daemonic footsoldiers of Nurgle. They are pestilential and bloated, riddled with disease, and they trudge forward in massed ranks to overwhelm the enemy. The rotted bodies of Plaguebearers are unnaturally hardy, soaking up volleys of explosive bolt shells and searing las-blasts without faltering. Meanwhile, their entropic plagueswords are hideous weapons, whose virulent slime rusts metal and rots flesh upon contact. As inexorable as the onset of a terminal sickness, the Plaguebearers shrug off everything the foe can hurl at them before bludgeoning them mercilessly into the dirt. It is the Plaguebearers' role to keep stock of new diseases and symptoms inflicted by the worshippers of Nurgle.
- Nurglings - Nurglings are diminutive plague imps that grow like cankers in the foul innards of the Plague God's Great Unclean Ones. They are tiny facsimiles of Nurgle himself that gather in excitable swarms, and spill over their enemies in a biting, scratching tide. When the Death Guard go to war, infestations of Nurglings appear spontaneously wherever they go. Many Death Guard find these effusive mites a constant annoyance, yet their presence is also believed to be a sign of Nurgle's favour, for the Grandfather does not entrust his squelchsome pretties to just any mortal servant. For all their mischief, Nurglings prove a surprisingly powerful asset when the fighting rages hot. Nurglings especially favour the vectoriums of the 4th Plague Company, gravitating towards those ruled over by Death Guard Sorcerers.
- Beast of Nurgle - Bounding into battle with dim-witted joy, the Beasts of Nurgle seek not to attack the enemy, but to play with them. Their affection is every bit as lethal as a volley of cannon fire, however, as Beasts of Nurgle are huge, slug-like abominations whose bloated weight can crush a man beneath their bulk like a spent ration tin. Worse, their noisome flesh seethes with lethal contagions, while septic slime drips from their every orifice. When they manifest in battle alongside the Death Guard, Beasts of Nurgle are cynically exploited as line-breaking units. The Death Guard have little time for the Beasts' attentions, and no more desire than most to be crushed under their galumphing weight. Thus they herd the beasts toward the enemy as best they can, often baiting the creatures with speeding tanks -- which they delight in chasing -- or bands of hapless Cultists. Should the Beasts be torn apart by heavy fire, those shells are at least not falling upon valuable Death Guard warriors. If the Beasts of Nurgle successfully punch a hole in the enemy lines, Mortarion's sons waste no time in exploiting their advantage.
- Plague Drones - High-ranking Plaguebearers riding atop monstrous Rot Flies, forming daemonic airborne cavalry known as Plague Drones. When they attack, they hit the enemy lines like hard-swung wrecking balls, bowling warriors over with their sheer stinking bulk. Meanwhile, the daemonic riders hack at their victims with plagueswords, and hurl infernal death's heads into the foe's ranks to engulf them in billowing clouds of plague spores and sickness. Such an onslaught is enough to break the spirit of even the most well dug-in opponents, and has been known to turn the flank or break the centre of entire enemy battle-lines. Though few know the truth of this, Rot Flies are, in fact, metamorphosed forms of Beasts of Nurgle who have given in to spite and despair.
- Poxwalkers - Poxwalkers are the cursed victims of Nurgle's plagues, transformed into the unliving weapons of the Death Guard. Infected with a cocktail of appalling maladies that breeds the dreaded Walking Pox, those affected by this malignant phage find their bodies rotting and shutting down until death eventually takes them. Yet this is not the end. The sufferer remains cruelly conscious and aware, trapped within their corpse as it reanimates with a rictus grin and staggers off in search of the living. Their flesh mutates even after death, sprouting bloated, pulsating tentacles and horn-like growths from their skulls similar to those of Nurgle's daemonic Plaguebearers. Countless souls have been lost in such a way to this malady, every one becoming another heretical abomination intent on murder. By the time the Death Guard move to attack a world so afflicted, they have an army of the dead waiting to aid them.
- Possessed - Some Heretic Astartes choose to open their bodies to possession by daemons of the Warp, becoming willing vessels for these infernal entities in exchange for the power that they can provide. Amongst the Death Guard, warbands of Possessed are rare. All Plague Marines enjoy the honour of carrying Nurgle's blessings within their rotting bodies, and for most this is enough. Yet there are those who, minds curdled by faith or enraptured by the sevenfold incantations of the Tallymen, offer themselves up to Nurgle's daemons as vessels. When a daemon possesses a mortal host, it reshapes their flesh like wet clay, moulding their mortal form however it pleases. The results of this agonising process are strongly influenced by the sort of daemon that performs the possession, and in the case of the Death Guard this will exclusively be those serving Nurgle. Such Possessed find single horns or antlers sprouting from their skulls. Their flesh becomes pallid and rotten like that of a corpse, or else gas-bloated, slime-slicked or fungal and moist. Insects seethe over and through bodies gifted with splintered bone talons, rotted fangs and chitinous armour plating. Tentacles and foul fronds wave from their reeking torsos, while paralysing ooze and corrosive pus spatters from their open wounds. Some even develop the bulbous eyes, feebly buzzing wings or needle probosci of plague flies. Through the symbiosis shared between the daemon and its host, the Possessed is stronger, tougher and altogether more deadly in battle. The daemon can heal its host form with surges of Empyric energy, while its might combines with that of the Plague Marine to create a truly fearsome whole. The price for such power is high, though; should the host ever be slain, they are banished alongside their possessor daemon, to be trapped forever as its plaything in the festering Garden of Nurgle in the Realm of Chaos.
- Chaos Spawn - Chaos Spawn are deranged abominations that live only to kill and feed upon the living, their former dreams of conquest and glory lost forever, as these former followers of their patron god are festooned with with useless appendages or mutations that greatly affect them in painful and debilitating ways. Eventually, these affected Champions of Chaos have their minds snap, as their bodies writhe and twist with the mutagenic power of the warp, and their last vestiges of humanity vanish amidst a seething mass of wet muscle, lashing tentacles and gnashing maws. They become Chaos Spawn, deranged abominations that live only to kill and feed upon the living, their former dreams of conquest and glory lost forever. So inured to discomfort are the Death Guard that many do not realise their bodies are becoming grossly overburdened until it is far too late. Such degenerate beasts are viewed by the Death Guard as little more than cannon fodder, walking barricades of groaning flesh that are herded into battle to soak up incoming fire and disrupt the enemy lines. For all this, the damage rampaging Chaos Spawn can inflict before they fall is hideous.
Vehicle and Armour Assets
Rusted tracks crush rubble and bone. Slime-clogged engines roar, spewing putrid smog into the sky. The ground shudders as though revolted by the passage of the Death Guard battle tanks and other vehicles. These pock-armoured behemoths bludgeon their way through the enemy lines to deliver lethal firepower and bands of warriors into the heart of the foe.
Despite his penchant for infantry tactics, Mortarion always recognised the role of heavy armour upon the field of war. However, during the years before the Horus Heresy, many of his Legion's tank crews were wholly Terran, and it was no accident that these were subsequently annihilated during the monstrous betrayal on Istvaan III.
The Death Guard have slowly replenished their tank brigades since that time, stealing and desecrating Space Marine tanks and churning out new vehicles from rusted manufactoria on stolen Forge Worlds. The Death Guard still treat their battle tanks as utilitarian supporting assets, not relics or noble constructs to be venerated, and prefer infantry-heavy assaults. Despite their subordinate role in the Plague Companies, however, the battle tank squadrons of the Death Guard and their other vehicle-class assets are a formidable force on the battlefield.
- Helbrute - Should a great champion of the Heretic Astartes be mortally wounded, they may be consigned to the armoured sarcophagus of a Helbrute so that they can continue to fight. Biomechanical war machines with armoured hides, these monstrous walkers excel in supporting infantry assaults with their punishing firepower and vicious close combat weaponry. Trapped forever within the Helbrute's innards, the husk of the champion is rendered functionally immortal. However, the claustrophobic horror and constant agony of his incarceration soon conspire to drive him mad. Helbrutes become little more than rampaging beasts, bellowing mindlessly as they storm into battle, desperate to inflict as much suffering on the enemy as they can in the vain hope of meting out a measure of their constant torment before being destroyed for good. Helbrutes are a common sight amongst the ranks of the Death Guard. So resilient are Mortarion’s sons that death does not come easily to them. Their unnatural fecundity keeps even the most sorely wounded champion alive long enough to be transplanted into a Helbrute sarcophagus, and ensures that the grafts and sutures take successfully. Mortarion's Plague Surgeons take a perverse delight in sealing rivals and superiors into these hellish mechanical prisons, chanting Nurgle's blessings of decay and rebirth as they do so. It is a testament to the stubborn determination of the Death Guard that most bear their incarceration with stoicism, and take far longer to devolve into insanity than the champions of other Traitor Legions. When not in battle, Death Guard Helbrutes are kept chained in the lowest decks of Plague Fleet warships, engulfed in cradles of squirming tendrils and slime-slick flesh. The machines feed parasitically upon the energies of the ship, healing their wounds and growing bloated and strong. By the time they are herded aboard heavy landers and ferried into battle, Death Guard Helbrutes are saturated with the blessings of Nurgle. Seething with unholy vitality, they storm the enemy lines like living battering rams, spreading airborne contagions and foul plagues even as they tear their enemies limb from limb.
- Foetid Bloat-Drone - Labouring through the air on buzzing turbines and driven by the trapped essence of a Nurgle Daemon, the Foetid Bloat-Drone drifts towards the enemy like an armoured plague fly. This hideous war engine bears monstrous weapons onto the battlefield to annihilate the enemies of the Death Guard. Clad in rusting plates of rot-iron armour, their hulls overflowing with flabby foulness, Foetid Bloat-Drones can withstand ferocious amounts of punishment and still keep fighting. They are designed to hover in close, drifting lazily through the most treacherous of terrain to provide supporting fire with their deadly and virulent Plaguespitters, which spit out a hideous cocktail of hyper-concentrated toxic slime. No cover or defence can protect the target from this lethal rain of filth. Victims find their bodies convulsing and twisting in the grip of a thousand maladies, rotting and bloating until they collapse into a heap of decaying, highly infectious matter.
- Myphitic Blight-Hauler - Powering into battle on a trio of articulated track units, the Myphitic Blight-Hauler is a light Daemon Engine that provides the Death Guard with heavy firepower wherever it is needed. Resembling a Bloat-Drone that has been stripped of its turbines, this strange machine has heavy weapons mounted on its carapace, typically a combination of Multi-Melta and Missile Launcher for mid-to-close range tank hunting. Most Death Guard commanders use packs of these Daemon Engines to fill the role that Havocs or Obliterators might in other Traitor Legions. The possessor entities that animate Myphitic Blight-Haulers are as loyal as hounds to their masters, rushing to obey any instruction they are given.
- Plagueburst Crawler - Plagueburst Crawlers are lumbering, formidable siege tanks whose huge ram-blades, thick armour plating and daemonic energies provide them with incredible resilience. Their fearsome Plagueburst Mortars boast a parabolic fire arc and terrifying range, while the shells they fire combine high-radius explosives with lethal clouds of corrosive spores to inflict damage comparable to that of Imperial Demolisher Cannons. Plagueburst Crawlers are not swift vehicles, even running at full power. Yet their advance is as grinding and relentless as the Death Guard themselves. Mortarion himself perfected the designs for the first Plagueburst Crawlers as a labour of pure spite as he sought to create a superlative mobile artillery piece that would outclass any comparative Imperial weapon, and thus demonstrate his Death Guard's superiority over their corpse-worshipping former kin. Mortarion's decision to make these vehicles Daemon Engines says much for his contempt for all living things.
- Defiler - Defilers are monstrous, crab-like Daemon Engines that clatter into battle on piston-driven legs. Their huge claws snicker and snap, chopping armoured warriors into bloody chunks and tearing open battle tanks to get at the screaming crew within. Their weapon arms send hails of shells or gouts of flame into the foe, while the Battle Cannon built into each Defiler's torso hurls explosive ordnance that leaves nothing but blasted craters wherever it strikes. The first Defilers were created by Warpsmiths on the order of Abaddon the Despoiler to support his Black Crusades. The news of their creation spread quickly throughout the Traitor Legions and Renegade warbands, and thus entire campaigns were fought for possession of the dark lore behind the process. Mortarion did not need to resort to such desperate measures. He simply demanded the requisite hexamechanic scrolls from Abaddon as tribute, and the Warmaster of Chaos -- seeing no advantage in antagonising one of the Daemon Primarchs -- provided them without question. A Daemon Engine is an animate killing machine, a construct of cold iron and cogwork powered not by plasma or Promethium, but by the infernal energies of the daemon bound within its hull. Such entities rage against their captivity, but they are powerless to resist, their wills captured and directed by the runic wards of their machine-prisons. The daemons of Nurgle are unusual, however, in that they adapt to their captivity more swiftly than the servants of the other Dark Gods. Whether through glum resignation or the gleeful realisation that such a form allows them to inflict all manner of mayhem, a daemon of Nurgle is much more amenable to being trapped inside a Defiler's shell. Once resident, the Daemon's essence infests the Defiler and leaves the unmistakable mark of Nurgle upon it. Metal rusts and lubricant clots and drips. Lambent slime oozes from the machine's joints, while pustules and sores mar its armour plates. A foul stench billows around Death Guard Defilers, of spoiled meat, ordure and other, unnameable effluvia, while clouds of flies buzz and crawl about them. The Death Guard maintain numerous Daemon Engine manufactoria, churning out steady streams of Defilers and other infernal war machines. From the Black Manse of the Plague Planet to the Scourge Stars, the summoning works of the Warpsmiths and Dark Mechanicum pulse with putrid energies and throng with chanting cultists day and night. Since the opening of the Great Rift, such practices have become far easier to maintain, allowing the Death Guard to amass huge packs of Defilers with frightening ease.
- Chaos Land Raider - Few battle tanks can match the indomitable might and exceptional utility of the Land Raider. Combining the firepower of an entire squadron of lesser vehicles with incredibly resilient hull armour, these behemoths are all but unstoppable on the battlefield. Their versatility is further enhanced by their ability to safely deliver even the bulkiest of armoured warriors into the thick of battle, disgorging their passengers to wreak havoc even as they unleash their own destructive potential to reduce enemy armour to scrap and annihilate infantry. Though they have striven to amass as many Land Raiders as they can over the millennia, still the Death Guard suffer from a paucity of these magnificent war engines. They are thus seen as status symbols within the Traitor Legion, and those Lords of the Plague Companies that have a considerable number of Land Raiders at their disposal take an uncharacteristic pride in their hard-won collection. As with all the battle tanks of the Death Guard, their Land Raiders are ripe with the dubious blessings of Nurgle. Parasitic horrors and unnatural plagues swarm through hulls that drip with foulness and are encrusted with revolting growths. Engines whine and drone like vast plague flies, spilling smog into the air in billowing, chemical-laden clouds. Weapons glow with leprous energies, and thrumming masses of bloated insects swarm and writhe around them. Some Land Raiders have been claimed as hosts by powerful daemons of Nurgle. These machines display a malefic sentience more akin to huge predatory beasts than war engines, and have been known to devour their crew, instantly heal battlefield damage, and hunt specific prey who have shown the audacity to fire upon them.
- Chaos Predator - Rumbling into battle with their heavy weapons blazing, Death Guard Predators provide mobile fire support for the Heretic Astartes advancing around them. Return fire rebounds from the Predators' bloated hulls, doing little more than bursting pustulous growths and spraying corrosive slime across nearby combatants. Driven hard into the enemy lines, squadrons of these repugnant battle tanks can destroy enemy armour, mow down ranks of opposing infantry, or eliminate key targets with their massed fire. Those Death Guard who crew Predators are often assigned to do so as a punishment, for it is seen as an ignominious duty. There are those who volunteer, relishing the thought of directing the tank's withering firepower, but they are a minority. Either way, the assignment is a one-way ticket. Imbued with Warp essence or claimed by daemonic entities, these tanks are sentient enough to have become morose and jealous things that resent their low status. When they acquire new crew they quickly claim them, biomechanical tendrils and mutated tubes growing into the bodies of the Plague Marines and fusing them permanently with their machineries. Over time, the crewmen are absorbed until they become little more than fleshy nodes within the Predator's hull, their personalities subsumed into the machine they serve. Most Death Guard Plague Companies maintain at least a few squadrons of Predators to operate as an armoured reserve. By comparison, the 2nd Plague Company fields dozens of these twisted war engines, building entire strategies around armoured spearheads, line-breaker assaults and heavy flank-attacks intended to crush the foe beneath the grind of their armoured treads.
- Chaos Rhino - Whether ferrying squads of Death Guard to new battlefronts, bearing them safely through hostile terrain, or moving them up in support of armoured offensives, the Rhinos of the Death Guard are ubiquitous and versatile. These armoured transports can carry up to ten power-armoured warriors within their festering holds, protecting them inside a cocoon of slime-smeared armour plating. Since the earliest days of the Great Crusade, the Rhino APC was the workhorse of the Legiones Astartes. Their reliability, durability and ease of repair all recommended them for this role. Those used by the Death Guard are riddled with rust, muck and decay, groaning and creaking as though on the verge of falling apart. Yet this could not be further from the truth, for the blessings of Nurgle saturate their very fabric. Mutant flesh and noxious matter binds their verdigrised hull-plates together, layers of rotting flab and swarms of burrowing parasites absorbing and diffusing the force of enemy fire. Anyone who has ever seen a Death Guard Rhino plough through a hail of enemy fire to disgorge its passengers into the heart of the fight can attest to the fact that these pugnacious vehicles are unnaturally hard to destroy.
Other Heavy Support Forces
Alongside phalanxes of battle tanks and monstrous Daemon Engines that regularly fight under their command, the Lords of the Death Guard can also call upon many other heavily armoured assets and deadly constructs to support their Legionaries in battle.
The corruption of Chaos is insidious, and amidst the filth and horror of war, many Astra Militarum regiments have sold their souls to Nurgle. Such turncoats bring with them entire divisions of powerful battle tanks and -- on occasion -- even behemoth super-heavy war engines such as Baneblades and Stormswords. Daubed with heretical slogans, festooned with gruesome trophies, these tainted battle tanks grind the foes of the Death Guard into the dirt.
Through torment or madness, the noble Knights of the Imperium also fall, on occasion, to the worship of Nurgle. A Knight is a forty-foot-tall bipedal war engine, a swift and deadly bringer of death whose limbs and shoulders mount devastating weapon systems. Each machine is operated by a single warrior, who is wired into the Throne Mechanicum at the Knight's heart.
Should a Knight transgress against his noble house, he will be exiled as a Freeblade, and it is these lonely and tormented individuals who most often fall to the temptations of Chaos. Even one Chaos Knight can rip through an enemy formation, while on those rare occasions when entire households fall, the Death Guard gain a terrifying force of allied war engines that can crush entire armies.
Greater and more terrifying still are the corrupted god-machines of the Traitor Titan Legions. Though these towering abominations are rare, even a single such engine can change the course of a campaign. From the swift and deadly Warhound-class Scout Titans to the walking fortresses known as Warlords.
The strangest and most arcane of all the Death Guard's allies are the secretive magi of the Dark Mechanicum. Once servants of the divine Omnissiah, these tainted Tech-priests have abandoned their faith in exchange for forbidden secrets and dark lore.
Those that worship Nurgle have learned the secrets of the living rust, viral scrapcode and the countless machine-poxes of the Engineflayer Tomes. They use this abominable wisdom to fashion monstrous engines of flesh, metal and daemonic energy. Such cursed war machines rumble into battle powered by soul furnaces, fed upon diseased corpses and unleashing eldritch weaponry that obliterates all before them.
The members of the Death Guard are also known as Plague Marines. As a result of their servitude to Nurgle, they are rife with all manner of deadly diseases, which renders them immune to pain. In practical terms, this makes them harder to wound and kill than other Chaos Space Marines.
While all members of the Death Guard are Plague Marines, not all Plague Marines are of the Death Guard Legion; other Chaos Space Marine armies may field Plague Marines as part of their forces.
Plague Marines under the tutelage of Mortarion know how to win a battle through sheer attrition. Because Mortarion intended for the Death Guard to rely heavily on infantry, the Death Guard are short some measure of fast assault vehicle and heavy weapons.
As a result, Death Guard Astartes without Terminator Armour normally have to settle for special weapons such as the Melta Gun and Plasma Gun to replace heavy weapons such as Lascannons and Autocannons.
Also, because the Death Guard are an infantry-based force, a Death Guard warband can be made up solely of Heretic Astartes with no armoured vehicles or daemons in its midst whilst still functioning as well as any other Chaos force that is better equipped. The average Death Guard Astartes can lay down a heavy rain of Bolter shells while still standing his ground if charged.
Many Plague Marines, particularly those who were originally members of the Death Guard Traitor Legion, still prefer to wear the Mark III Iron Pattern suits of Power Armour first used during the Great Crusade.
Even though more modern marks of Power Armour had become available to them before the Horus Heresy, the Death Guard retained a large stockpile of the heavier Mark III pattern, preferring it both for its durability and the ease with which they could customise it to better handle the rigours of the often-toxic battle zones in which the Legion excelled.
The armour of Plague Marines, regardless of its type, usually suffers from severe corrosion and structural breaches over its millennia of service with a corrupted Astartes.
Plague Marine Power Armour is often further modified with the inclusion of a heretical pattern "open vent" reactor backpack and blasphemous inconography as well as swelling or even cracking like a broken egg shell to contain the grotesquely mutated physique of its wearer.
Special Weapons and Wargear
What follows is a small selection of the unusual wargear and special abilities which can be used by members of the Death Guard:
- Nurgle's Rot - Nurgle's Rot is a virulent psychic power granted to some members of the Death Guard by Nurgle to use at will. The horrific plagues of Nurgle are summoned and unleashed upon the enemy. Those not tightly armoured are instantly affected, and quickly killed by the supernatural infection.
- Blight Grenades - Plague Marines also carry weapons known as Blight Grenades or "Death Head Grenades." These grenades are made from the heads of conquered foes of Nurgle. Constructed by Nurglite Chaos Sorcerers, the severed head is covered with a waxy mix of organic slime and contaminated blood until it is watertight. The brain cavity is then filled with pus and left to fester, becoming a poisonous gas. The result is a missile that bursts on impact, releasing a deadly acidic vapour laced with various pathogens that is capable of eating through most forms of personal armour.
- Manreaper - A Manreaper is a powerful Daemon Weapon that is a unique form of Power Weapon that pays homage to the Death Guard's Primarch Mortarion. Manreapers are carried by Chaos Champions of Nurgle, such as Typhus the Traveller. The weapon often takes the shape of a large Power Scythe, enabling a warrior to face many times their number in battle, cutting them down like a reaper through a field of ripe crops. Manreapers are also covered in a corrosive poison that contains a vicious toxin, allowing the bearer to wound his opponents with ease.
- Plague Knife - The hallmark weapon of the Death Guard was their close combat blade, a broad trench dagger, which was a brutal and efficient weapon in hand-to-hand combat. When Astartes of the Death Guard were transformed by the corrupting influence of Nurgle, these blades transformed as well. Now they have become Plague Knives, corroded weapons coated with rust and numerous diseases, the better to spread Father Nurgle's vile blessings across the galaxy. Only those pure in his sight such as his Plague Marines are granted such a weapon, and any lesser being suffering even the slightest wound is gifted with one of his innumerable creations such as Nurgle's Rot or the Weeping Pox.
- The Destroyer Hive - The Destroyer Hive is a vile ability only available to Typhus, the "Herald of Nurgle." It is a monstrous swarm of plague-infested flies, so numerous they blot out the sun and flood the air surrounding Typhus with contagions. It was the prize granted to Typhon when he delivered the Death Guard to Nurgle, his very body now transformed into a host for this innumerable horde of Nurgle's sacred animals.
Legion Combat Doctrine
When the XIVth Legion was still known as the Dusk Raiders, its Astartes signature strategy had been to attack their foes at nightfall, thus earning them their Legion moniker. The Dusk Raiders' Power Armour was an unpainted slate grey in colour while their right arm and one or both shoulder plates were painted crimson.
This was done with the intent to symbolically show their enemies what they truly were -- the Emperor's red right hand, relentless and unstoppable. Many enemies would throw down their weapons the moment the sun dipped beneath the horizon rather than dare to fight them.
With the coming of Mortarion, the Legion's combat doctrines changed as the Death Guard became a single instrument of his will. The Death Guard came to believe that victory came through sheer relentlessness. Their weapons, while not ornate, functioned without flaw. They did not manoeuvre in fanciful patterns to confuse the enemy, instead they stood their ground and waited for the enemy assaults to falter before striking back with fatal force.
Any environment or situation Mortarion and his advisors could not compensate for, the Death Guard would overcome through sheer stubborn resilience and painful endurance. Mortarion had learned the art of warfare on a world almost covered in mountainous terrain, and even though his innate intellect allowed him to grasp the proper use of tanks and armoured vehicles, the primacy of the foot soldier remained the Death Guard's trademark. Each Space Marine was well-trained in a variety of infantry disciplines, and was able to function in almost any role or environment.
The Death Guard were arguably the most remorseless and among the most feared of the Space Marine Legions. This was not simply because of their power in battle or force of arms, but also because there seemed to be no loss they would not accept to ensure eventual victory and no hell they would not endure to reach their foe.
Although specialising in entrenched and attritional warfare, the Legion also had a number of formations and tactics that enabled it to operate in concentrated and crushing force in an attack -- one such was dubbed "The Reaping" by those who had fought alongside the Death Guard during the Great Crusade.
A heavily reinforced column of attack particularly suited to urban warfare and shattered landscapes, the Reaping was deliberately slow-moving and utterly murderous in its methodical assault pattern and, like the reaper's scythe, little escaped it.
After the Death Guard was transformed by the Plague God and turned into a Legion of Plague Marines, they preferred to engage in short-ranged firefights, where they could see the festering wounds inflicted upon their enemies whilst they shrugged off the bolts and las-blasts directed back at them. Their decaying brains are inured to the agony of the bodily corruption that runs rampant in their diseased carcasses, making them all but immune to the pain or discomfort caused by battle wounds.
When their enemies close within assault range, Plague Marines make use of their Blight Grenades and release the virulent toxins that they contain, which proceed to eat away at armour and fill the air with thick noxious clouds of blinding, pathogenic spores. The most virulent and flamboyant of these Blight Grenades are made from the severed, decaying heads of their fallen enemies.
It is of note that the Death Guard under Mortarion quickly became associated with the use of alchemical and radiation weaponry to a greater extent than any other Legion, further darkening their reputation with the Battle-Brothers of the other Legiones Astartes.
Simply put, the use of toxic gas, burning Phosphex and contaminated rad-shells did not rankle their Legion's honour as it did for some, while Mortarion himself was a master in the use of such weapons of mass destruction and a student of the most horrific arts of war, and had no compunction in their use against any foe that threatened humanity.
The Death Guard Astartes' inherent resilence to toxins and poisons enabled them to be deployed to warzones afflicted by the most hellish and lethal conditions, be they atomic, biological or chemical in nature, in which they would then excel.
The Great Crusade was, after all, launched to conquer worlds and not destroy them, unless there was no alternative, but in such war zones, already hopelessly contaminated and unsuited for human life, the usual caveats and protocols restricting the use of contaminate weapons by the Emperor's command did not often apply.
Barbarus was a Feral World which orbited near its dim yellow sun in the Segmentum Tempestus, which created a thick, miasmic atmosphere of toxic chemicals. The most virulent of these gases rose through Barbarus' perpetual clouds towards the heat of its star, making the world beneath a dismal place of night, unbroken by starlight and with short, shadowy days.
An atmosphere breathable by humans existed only in the lowest elevations, on flat moors and in the valley basins of the jagged, stony mountains which spined the world. Unknown alien beings immune to the toxic soup of the planet's higher atmosphere existed on Barbarus, building great keeps of grey stone in the mountain fastnesses.
When humans first settled Barbarus, the horrific environmental conditions from which they had to eke out survival quickly reduced them to a pre-feudal state. The higher beings' incomprehensible Warp-based powers, their ability to survive where humanity could not, and above all their hunger to prey upon, experiment with and accurse humankind, caused the settlers to ascribe to those beings a medieval supernaturalism.
The true nature of these dark overlords, beyond their obvious connection to the dark entities of the Empyrean, will likely never be known. Barbarus is assumed to have been destroyed by an Exterminatus order issued by the Inquisition after the end of the Horus Heresy, like all the other worlds belonging to the Traitor Legions.
Mortarion has crafted a new home from a Daemon World called the Plague Planet within the Eye of Terror, which resembles ancient Barbarus, Mortarion's original homeworld, remade in yet more hideous hues, a fume-wreathed nether-hell where disease runs rampant and barbarian tribes cling to a nightmarish existence amidst rotting forests and swamps.
Worm-eaten mountains rise to pierce the churning skies, their flanks roamed by plague-ridden abominations that should be dead yet still prey on human flesh. Higher, atop the peaks, the Death Guard maintain their fortresses as once the carrion lords of Barbarus ruled from on high, revelling in the bitter irony that they have become the very despots they once fought to depose.
The clouds of contagion that wreathe these slab-sided, rusting fastnesses are inimical to life. None but the Death Guard can endure even a single breath of them. Quite besides the brutish batteries of orbital guns that stud every single mountaintop of this world, its vapours alone have proved enough to massacre invading armies on more than one occasion.
The Plague Planet is replete with hideous spectacles and places of foetid power. Amongst the suppurating valleys rise tri-lobed platforms of rusted iron upon which mortal tribal champions battle for the right to join the Death Guard's ranks. Hanging in orbit are chained rings of biomechanical defence platforms and suppurating orbital docks, at which the Plague Fleets suckle like flies on a carcass.
Shrines to Nurgle, crawling molluscoid fortresses, smog-spewing plague factories and crackling alchemical shield generators dot the planet's surface. The world's mortal citizens cower in tiny villages, serving their supreme masters of the Death Guard, who reside in mighty fortress citadels far above all of them.
Greatest of all, though, are the seven mountaintop keeps of the Death Guard's Plague Companies, one company ruling over each in their own uniquely revolting fashions.
The largest of these, known as the Black Manse, stretches between the three highest peaks of the Plague Planet and serves as Mortarion's personal keep. The dungeons and laboratories of this nightmarish fastness conceal horrors of the very darkest kind.
The beliefs of the Death Guard before the outbreak of the Horus Heresy echoed those of their Primarch. At the heart of their core beliefs before the Heresy was the unshakeable determination that Mankind should be free of oppression and terror. Such freedom could only be won by destroying those that would shackle and devour humanity.
The battle for the future of Mankind was one that could only be achieved through the endurance of any hardship, no matter how terrible. The liberation of humanity justified the ultimate use of any means.
The Death Guard's faith in inner strength, iron will and unshakeable resolution in the face of hardship led to overweening pride, arrogance and an utter contempt for those they deemed inferior. When Nurgle's Rot laid the Death Guard low during their time trapped in the Warp before the Siege of Terra, their pride and arrogance in their strength and contempt for those they deemed weak was laid bare.
The Plague Marines' subsequent surrender to Nurgle left the Death Guard with an incredible depth of self-hatred and despair that only fuels their sole desire: to infect the strong, slay the weak and bring everyone and everything to rot and ruin.
In their eyes, their own debasement would no longer seem as shameful if Nurgle's pestilence dragged the rest of the galaxy down into the same depths of ruin and despair.
Cult of Personality
The arrival of the Primarch Mortarion within the XIVth Legion in the later days of the Great Crusade seemed to augment and amplify characteristics that had always been present in the Dusk Raiders to new and unseen extremes, while other aspects of the Legion's established nature fell away like a shed skin.
Mortarion possessed a razor-sharp intelligence and flare for organisational simplicity and efficiency. These factors, coupled with the ability to inspire a fanatical loyalty in those of Barbarus blood who viewed him as no less than a near-divine saviour, engendered a fanatical loyalty to its Primarch rarely seen in other Legions.
It was no wonder then that by the time of the Istvaan III Atrocity, with the majority of the Legion being of Barbaran bloodstock, that their loyalty was to their Primarch first, then their Legion and to Horus.
The majority of the Barbaran-born Death Guard Space Marines were more than willing to spit upon their oaths of fealty to the Emperor of Mankind and cast their lot with their macabre Primarch when the time came, a decision which ultimately encompassed the XIVth Legion's doom.
When Mortarion reorganised the XIVth Legion's organisational structures he reorganised them into seven Great Companies. The number seven and its derivations seemed to hold occult and ritual significance both to Mortarion and the Barbaran culture of his blighted world of adoption.
Notionally each company was to hold some 70,000 Space Marines, meaning that the desired total strength of the Death Guard Legion was some 490,000 Astartes, although in reality nothing approaching this number was ever achieved.
Attrition and bloodshed, as well as the constraints of time and Imperial resources, were to ensure that the XIVth Legion never reached this number but the figure remained, if nothing else, a measure of Mortarion's ambition.
The Death Guard cared little for emblems of rank, except where needed for battlefield recognition. Nor did the Astartes of the Death Guard care for badges of honour or other trinkets to commemorate deeds of valour.
The closest the Space Marines of the Death Guard came to such decoration was respect for the marks of battle itself on their armour, be they from an enemy's blade or bullet, or the corrosive stains of a toxic environment none but the Death Guard could have endured.
So long as the integrity of the armour plate itself was not compromised, such damage was left to adorn a Death Guard Space Marine's armour as a statement that there was nothing they could not endure, adding to the XIVth Legion's increasingly sinister appearance and deepening reputation among their fellow Astartes during the Great Crusade.
Often, a Battle-Brother of the Death Guard would be singled out by Mortarion, who would then offer the selected warrior the rare opportunity to share a celebratory drink with him. It was said that there was no toxin too strong, no poison so powerful and no contagion of such lethality that a Death Guard could not resist it.
The Death Guard were known to harden themselves through stringent training regimens as Neophyte Astartes, willingly exposing themselves to chemical agents, contaminants, deadly viral strains and venoms of a thousand different shades. They could resist them all.
From a set of bowls was mixed and poured dark liquids into a pair of ornate goblets. The senses of the chosen Astartes often rebelled against the odour of the toxins, their implanted Neuroglottis and Preomnor organs rebelling at the mere smell of the poisonous brew; but to refuse the cup would be seen as weakness.
The poured distillate often contained a potent mixture of agent magenta nerve bane, some variety of sword beetle venom, and other, less identifiable compounds. The cups were Mortarion's, and in each battle where the Death Lord took to the field in person, he would select a warrior in the aftermath and share with that warrior a draught of poison. They would drink and they would live, cementing the unbreakable strength of the Legion they embodied.
Mortarion understood that many within the Legion frowned upon such traditions as "The Cups," but the Primarch knew that honours and citations were sometimes necessary. Warriors needed to know that they are valued. Praise from one's peers must be given when the moment was right. Without it, even the most steadfast warrior would eventually feel unvalued.
The Legionaries of the Death Guard always reflected the gaunt, shadow-eyes quality of their Primarch that gave the lie to the hardness with which they were made. The original Terran-stock displayed a stoic temperament and gene-crafted aptitude, reminiscent of their genetic inheritance from the Ironside warriors of Old Albia.
With the introduction of the feral stock of the pale, gaunt people of Barbarus, the Death Guard Legion's gene-seed seemed to amplify the uncommon resistance to contagion and toxins in its Barbarus candidates to unheard of levels.
The contagion which led to their damnation corrupted them physically, as well. As Plague Marines, the once-gaunt Death Guard are now bloated and seeping like an infected abscess, covered in boils, sores and weeping wounds crusted with the brown and green filth of the unclean.
Nurgle does not accompany this repulsive aspect with gifts of mutation as freely as the other powers (such capricious change is the province of his antithesis, Tzeentch), but on occasion will alter the countenance of a Death Guard aspirant with a tentacle, facet-eyed head of an insect or some other hideously repulsive form.
Before the Heresy the Astartes of the XIVth Legion would shout "For Terra and Mortarion!" when they entered the fray and the 7th Great Company in particular used the cry "Count the Seven!"
Since their fall, the Death Guard have no rallying warcry, believing that like plagues and pestilence, death should come silently. They are pestilence and pox, famine and blight, contagion and cancer, and like all of these things, are most terrifying when they come without word or warning.
Notable Death Guard
- Mortarion - Also known as the Death Lord or the Prince of Decay after he turned to Chaos, Mortarion was one of the original twenty Imperial Primarchs created by the Emperor of Mankind. He was given command of the Death Guard Space Marine Legion on the arrival of the Emperor to his homeworld of Barbarus, but he turned to the Forces of Chaos during the Horus Heresy. At present, Mortarion is the greatest Daemon Prince of Nurgle and the Daemon Primarch of the Death Guard Chaos Space Marines.
- Typhus the Traveller (formerly First Captain Calas Typhon) - The first Astartes of the Death Guard to turn to the service of Chaos in his desire for power, Calas Typhon, once the First Captain of the Death Guard's 1st Great Company and the second greatest Astartes in the Legion after the Primarch Mortarion, is now known as the Herald of Nurgle and the Host of the Destroyer Hive, perhaps the most terrible of the many pestilences unleashed on the universe by Nurgle. He is still in command of the powerful Chaos Battleship Terminus Est, which has been under his control since the Battle of Istvaan III during the Horus Heresy, though it has been warped by the power of Chaos and the Plague Lord since those long-ago days 10,000 years ago.
- Commander Ignatius Grulgor - Captain of the 2nd Great Company. During the massacre on Istvaan III Grulgor was posted on the Eisenstein to kill Captain Garro and the hundred strong company of Astartes with him. Was killed for the first time in a firefight in the gun decks of the Eisenstein, after a stray bolt pistol shot released the Life-Eater virus intended to be fired on Istvaan III. After the Escape of the Eisenstein and the following Warp journey, the body of Grulgor was reanimated by the Ruinous Powers as one of the very first Plague Marines ever encountered by the Imperium. After a desperate battle, Grulgor's mutated body was destroyed when the Eisenstein made an emergency transition back to realspace and the Plague Marines' connection to their patron Nurgle's domain was suddenly extinguished, causing their souls to be returned to the Realm of Chaos. However, it is likely that Grulgor survived these events as a newly transformed daemonic spirit, for a Nurgleite Daemon Prince known as Grulgor led the Forces of Chaos during the Fall of Medusa V campaign in the late 41st Millennium.
- Ullis Temeter (Presumed Deceased) - Temeter was the Captain of the 4th Great Company of the XIVth Legion. Temeter remained loyal to the Emperor, despite the spread of corruption throughout his Legion. He met his ultimate fate on the surface of Istvaan III. When Saul Tarvitz of the Emperor's Children brought warning of the Warmaster Horus' treachery, Temeter and hundreds of Loyalist Astartes sought cover as Horus ordered the viral bombardment of the planet. Thanks to Tarvitz's last minute warning, some of the Loyalist forces were able to take cover in air tight bunkers. Temeter, not being able to make it inside the safety of one of these bunkers, ultimately perished in the ensuing viral bombardment.
- Battle-Captain Nathaniel Garro - Nathaniel Garro was the Battle-Captain of the Death Guard's 7th Great Company. Leader of the 70 surviving Astartes who alone of the Death Guard Loyalists escaped the betrayal of Horus on Istvaan III aboard the Imperial Navy frigate Eisenstein to bring word of Horus' betrayal to the Emperor. He held to the original tenets of the Legion when many of his Battle-Brothers chose to follow the Traitors, Horus, Mortarion, and First Captain Typhon's decision to serve Chaos and conquer the Imperium for themselves rather than trust in the will of the Emperor. After a lucky rendezvous with the Imperial Fists' space fortress Phalanx, news of Horus' treachery was brought to Terra and the Emperor, which could well have saved the Imperium. While his historical fate is uncertain, it is believed that Garro, along with the remaining Loyalist Luna Wolves Astartes, Iacton Qruze, was ordered by Malcador the Sigillite to gather 8 Astartes from both the Loyalist and Traitor Legions across the galaxy. who would later form the precursor of the Grey Knights Chapter of Space Marines, and along with 4 lords and administrators of the Imperium would forge the secret organisation that would later became the Imperial Inquisition. After arriving on Terra, Garro's Power Armour had all of its Death Guard regalia removed and replaced with the personal sigil of Malcador, an "I" with three horizontal lines through its center, the icon that would later become famous as the Rosette of the Inquisition. During his mission for the Sigillite, Garro consistently referred to himself as a "Knight Errant" and the member of a "Legion of One". Garro wielded the potent relic Power Sword called Libertas.
- Marshal Durak Rask (KIA) - Durak Rask was a fanatical follower of his Primarch, viewing Mortarion as a preternatural saviour from his early youth on the benighted world of Barbarus. Accepted into training for the Death Guard Legion, Rask was marked from an early age for his innate intelligence and fervour. He quickly proved to be a dour and driven warrior with an uncommon flair for siegecraft. He soon rose over his solar decades of service to become the Legion's Marshal of Ordnance, and proved his mettle in many battles and campaigns. When Mortarion declared his allegiance for Horus at the start of the Heresy, Rask was one of the first and loudest in his support, having already become a member of the Seven Pillared Lodge which had been founded within the Death Guard as a warrior lodge to corrupt them towards the service of Chaos from within. On Istvaan III Rask volunteered to lead the vanguard attack against his former Battle-Brothers, a treachery he would pay for with his life.
- Solun Decius - Decius was a member of the 7th Great Company commanded by Battle Captain Nathaniel Garro, and the youngest member of Captain Garro's command squad. Brother Decius remained loyal to Garro, despite the corruption that had begun to creep into the Space Marine Legions under Warmaster Horus' command, in the form of the warrior lodges. Garro expressed his disapproval of the secretive lodges and so, Decius chose not to join the warrior-lodge that existed inside the Death Guard when offered membership. Being a part of Garro's command squad, he was aboard the Eisenstein when his Captain took control of the vessel and fled the Isstvan system in an attempt to bring word of Horus' treachery to Emperor. Enroute to Terra, Decius and a number of his fellow Death Guard fought a battle against the reanimated corpses of their former traitorous comrades, the first Plague Marine of Nurgle. Decius was grievously injured when he was stabbed by one of the Plague Marine's deceased knives, and in a vain attempt to halt the vile corruption, he bravely cut off his own arm. The severely wounded marine was then taken to the Apothecarion and put under the care of Apothecary Voyen, but alas, there was no cure to be found to ease young Decius' suffering. After completing their arduous journey and delivering their message to the Emperor's acting Regent, Malcador the Sigillite, Garro and his men were placed under house arrest and held in solitary confinement in a fortress on Luna, under the watchful eyes of the Silent Sisterhood. Their fate was yet to be decided. In the meantime, the mortally wounded Decius finally lost his fight to the Nurgle's Rot that ran rampant throughout his deceased and corpulent form. Giving himself fully to Father Nurgle, Decius' body metamorphosised into the mutated form of the daemonic entity, known as the Lord of the Flies. His twisted body took on a daemonic appearance; arachnid-like head with numerous eyes and mandibles in place of its mouth, his decapitated arm growing grotesquely into a large power claw-like, great skeletal hand. The Lord of Flies wrecked havoc inside the fortress killing two former comrades before Captain Garro strode forth and slew the monstrosity outside the fortress on Luna's surface, casting the Lord of Flies' daemonic spirit back into the Warp from whence it came.
- Meric Voyen - Meric Voyen was the company Apothecary of the 7th Great Company commanded by Battle-Captain Nathaniel Garro. Garro was furious with Voyen when the Apothecary confessed that he was a member of the secret warrior lodges that had begun to spring up in the XIVth Legion. Garro let it be known to his men that he did not approve, for he felt that these lodges, though they had their worth, were ultimately predicated upon secrecy and the act of concealment which were anathema to the Astartes, and he would take no part in it. He later pulled Voyen aside and confronted him in private. Though he formally censored the Apothecary for being a member of the warrior lodges, he made the Apothecary swear to him that he would never keep any secrets from him. Voyen readily agreed, but knew in his heart that it would take much to regain his commander's trust. During the Istvaan Campaign, Garro's 7th Great Company fought in concert with the Emperor's Children's elite 1st Company against traitorous forces on Istvaan Extremis, the outermost planet within the Istvaan System. Whilst fighting against a powerful Slaaneshi psyker known as a Warsinger, Garro sustained serious injuries that included crushing damage to his torso, arm and the loss of his right leg from the mid-thigh down. He was only saved from certain death by the timely ministrations of an Apothecary from the Emperor's Children Legion -- their Chief Apothecary Fabius -- much to Voyen's displeasure. The Legion's Apothecaries had not declared him fully healed and therefore Garro was deemed unfit for battlefield operations. His command also remained on limited duty until Garro was fit to reenter combat. As a result, Garro and his company were not among the Death Guard Loyalists assigned to unleash the speartip assault upon Istvaan III, so they remained aboard the Frigate Eisenstein providing standby tactical support for the Drop Pod deployment operation, and remained on alert to perform rapid-reaction interdict duties. Before the mission began, First-Captain Calas Typhon pulled Commander Ignatius Grulgor, the Captain of the 2nd Great Company, aside and spoke to him of their Primarch's desire to bring Garro to Horus' banner over the Emperor's, but they both knew that Garro would never betray the Master of Mankind. When the turning point arrived, Typhon informed Grulgor that there were certain duties that Horus would want him to perform. The Commander relished his part in this conspiracy against Garro, whom he had long found insufferable. Aboard the Eisenstein, suspicious of Commander Grulgor's actioins, Apothecary Voyen stealthily made his way to the launch bay to investigate. Voyen saved Garro's Housecarl Kalab from narrowly being captured by Grulgor's men. Kalab shared with Voyen that he had seen Grulgor and his men loading an unusual cargo aboard the frigate. Digesting what the housecarl told him, Voyen realised with growing horror that the deadly cargo were Life-Eater virus bombs -- biological weapons that contained an engineered viral strain of such complete lethality that it could only be deployed in the most extreme circumstances, usually against the most foul xenos. Informing his commander of Grulgor's actions, Garro decided to confront the treacherous commander. With only Apothecary Voyen, Battle-Brother Sendek and his housecarl, Garro confronted Commander Grulgor and his entire command squad and a handful of the frigate's crew. A vicious fight ensued and Garro and Voyen narrowly avoided death. Grulgor and his men suffered the lethal effects of the Life-Eater pathogen when it was accidentally released by a stray Bolter round that punctured one of the warheads, and Grulgor and his men died screaming in agony. During their flight to Terra to bring warning to the Imperium of the treachery of Horus, Voyen second-guessed his commander's actions multiple times, but ultimately, Garro's desperate gamble of detonating the Frigate's Warp engines when they became trapped in the Warp and were under assault by the undead Plague Marines of Nurgle, paid off. They were rescued by the Primarch Rogal Dorn and his Imperial Fists Legion. Aboard the Phalanx, they brought word of Horus' treachery to his stern brother. The Imperial Fists brought Garro and his men to Luna, where they were imprisoned within the Somnus Citadel of the Silent Sisterhood. One of Garro's men, Solun Decius, finally succumbed to the mysterious contagion he had contracted when the Loyalist Death Guard were confronted aboard the Eisenstein by the reanimated corpses of Grulgor and his men -- the first true Plague Marines. A vicious battle ensued, and Garro was able to destroy the Chaos-tainted daemon that had possessed Decius' tortured body. Following this final battle, Voyen informed Garro of his intentions to renounce his oaths as a warrior in order to dedicate his life to healing and the discovery of a cure for the mysterious contagion contracted by Decius, which was later identified as the first known case of Nurgle's Rot.
- Crysos Morturg - Section Leader Crysos Morturg was a bitter warrior, morbid and given to introspection. He was disliked by his Battle-Brothers despite his evident talents as a warrior and field commander. He was neither Terran nor Barbaran by birth, having been inducted into the Death Guard Legion during an emergency influx of recruits from the induction pool of the 18th Expeditionary Fleet after the Death Guard suffered near-catastrophic losses during the Rangda Xenocide campaign of the Great Crusade. Years after his induction, after he rose to the rank of Lieutenant, his latent psychic abilities manifested. This only served to further isolate him from his fellow Astartes, and he had barely begun his training within the Legion Librarius when Mortarion had it disbanded and ordered such "witchcraft" suppressed. Morturg was reassigned to the Legion's Destroyer Corps and was often given Legionaries judged to be fractious or unstable, and his unit was tasked to the brunt of the worst fighting the Death Guard endured. During the campaign against the Traitor Legions' Loyalists on Istvaan III at the start of the Horus Heresy, he was marked for death and sent to the surface on the doomed world. But Morturg did not die and instead endured, rising to become one of the most deadly commanders of the Loyalist resistance. Despite all the odds, Morturg survived the atrocity on Istvaan III and he and the few remnants of the slaughtered Loyalists he had gathered to him would live to avenge themselves upon their former brethren. Crysos Morturg's ultimate fate is unknown.
- Forge Tyrant Erud Vahn - Erud Vahn had once been counted amongst the foremost Forge-Tyrants of the Death Guard. Acknowledged grudgingly by the grim master of his Legion, Mortarion, as a master of the esoteric disciplines of alkemic warfare, Vahn had spent long years in study with the tech-adepts of Mars. With the outbreak of the Horus Heresy, Vahn found his loyalty to the Mechanicum outweighed that to his distant Primarch and declared for the Loyalist cause. Seconded to the command of Blackshield Praetor, and former World Eater, Endryd Haar, for his knowledge of the more esoteric mysteries of the Machine Cult, Erud Vahn led the infiltration force upon the Forge World of Xana II, that boarded and later seized control of the Ordinatus Minoris Ashurax. Of the twelve Techmarines of the Loyalist Legions who entered the sanctum at the heart of the Ashurax, only five would survive the attempt. Erud Vahn's ultimate fate is unknown.
- Loyalist Legionary Kalaeb Molor - Kalaeb Molor fought as part of a resistance group under the command of Crysos Morturg and was valiantly slain in battle against the Traitor forces of the World Eaters Legion.
- Loyalist Sergeant Sorruk Vasha - Vasha was a Tactical Squad Sergeant of the Death Guard's 4th Great Company who took part in the initial assault wave sent against the rebels of Istvaan III, and owing to damage sustained by his Power Armour during the battle, Vasha perished to the ravages of the Life-eater virus during the initial bombardment by the Traitors which unleashed the Istvaan III Atrocity.
- Ancient Lhorgath - Ancient Lhorgath was once the commander of the 14th Chapter, 2nd Great Company of the Death Guard Legion, a rank he reluctantly set aside upon being mortally wounded battling the Fane-Kings of Narbasi during an Imperial Compliance action. At the Istvaan V Drop Site Massacre, Ancient Lhorgath led his Dreadnought Talon in a fearsome counter-charge into the midst of the Salamanders Legion in the battle's bloody final hour; it is claimed Lhorgath was struck down by Vulkan himself in the desperate fighting. Lhorgath's Contemptor Pattern Dreadnought chassis was an exemplar of the prototypes of the type delivered to the Death Guard Legion's armouries which were subjected to numerous repairs and modifications by the Legion's Artificers.
- Legionary Sollan Gath - A Tactical Legionary who served in the 33rd Tactical Squad, 6th Great Company in the "Despoiler" role -- armed specifically for close-quarter fighting. He was known to favour weapon combinations such as utilitarian high strength Combat Blades and the Bolt Pistol. Analysis of the Death Guard Legion's crushing assault on Dominica Minor suggested that many line units, such as the 33rd, deployed directly into the civilian sectors, ruthlessly and dispassionately slaughtering everything they encountered, be they planetary militia or fleeing civilians. Legionary Gath's ultimate fate is unknown.
- Legionary Kahgor Lothsul - A Veteran Death Guard Space Marine Legionary and Warrior Lodge member who was mortally wounded fighting Ork marauders on the world of Huashta a little less than a standard year before the Istvaan III Atrocity. The fight on Istvaan III would be his first and last battle for his Legion in his Contemptor Pattern Dreadnought chassis. Operating as part of a hunter-killer detachment during the heights of the ash storms that engulfed the Choral City after the firestorm unleashed by the Life-eater virus bombing, Lothsul was ambushed and destroyed by Ordo Reductor Thallax forces, and his remains scavenged before they could be recovered by Death Guard counter-attack.
- Legionary Koloth Vorr - Legionary Koloth Vorr served in the Heavy Assault Reserve, as one of the 7th Great Company's "Grave Warden" cadre, a body of warriors specialising in the extremes of bio-chemical warfare and used in ever-increasing numbers throughout the entirety of Mortarion's Legion during the Great Crusade and subsequent Horus Heresy. He wore Cataphractii Pattern Terminator Armour, which had been modified with the distinctive technological adaptations of the Grave Wardens. This armour featured the integrated Deathcloud chemical projector, its distinctive discharge stacks visible on the bearer's back. Legionary Vorr's ultimate fate is unknown.
- Ancient Skorrvall "Bitterblood" - Skorrvall was the commander of the Death Guard's 7th Dreadought Talon. Skorrvall was a native of Barbarus from that world's intake into the Death Guard Legion and was known as a darkly-tempered warrior and a survivor against the odds. Rising to the honoured rank of Standard Bearer of the 19th Chapter of the Death Guard's 1st Great Company, he was mortally wounded in battle with the Eldar at Neverlight and interred in a Dreadnought frame. Fighting with the Traitors in Mortarion's Vanguard at Istvaan III, he killed indiscriminately during the "Veil of Grief" incident and was badly damaged by cannon-fire but survived to later take part in the Drop Site Massacre at Istvaan V.
- Buorgdius - Buorgdius is a malevolent Champion of Nurgle, whose plaguefleet plies the outer fringes of the Screaming Vortex in the Calixis Sector, unleashing its revolting warriors against those unfortunate enough to fall afoul of their diseased and leprous hulks. In combat, Buorgdius leads the reanimated corpses of his former Space Marine brethren into battle while wielding a massive mace crafted from the diseased bones of his unholy predecessor, and dripping with repellent Warp energies. Afterward, his undead warriors stuff the innumerable dead and dying into the filthy, dank plague holds of his vessels in order that they may moulder in the foetid darkness. In this way, the champion recruits many of his mightiest warriors, and he is said to offer a place in his warband to any who will but supplicate themselves before the Lord of Decay.
- Necrosius - Necrosius was once an Apothecary of the Death Guard Legion during the Great Crusade whose original name has long been purged from all Imperial records. During the early days of the Horus Heresy, soon after the Death Guard turned against the Emperor of Mankind, when the Traitor Legion's fleet was becalmed in the Warp on the way to Terra and assaulted by the infectious corruption of Nurgle, the man who would become Necrosius the Undying and his fellow Apothecaries among the Astartes of the Death Guard turned their every art and skill against the strange plagues sweeping their ranks. But it was all to no avail. When Necrosius heard the voice of his new lord chortling and whispering to him in the murmerous wings of carrion flies and the sibilant gurgling of rotted, decaying organs, he fully accepted the nightmare truth of what he and his fellows had become, and embraced the service of his vile God. Necrosius became a true convert to Nurgle's cause, casting aside his past learning and cherished role as a healer of his Battle-Brothers. He now chose to give himself, blighted soul and rotted body, to the lore of death and the pursuit of daemonic sorcery, and soon excelled as a master of the dark arts of necromancy. Now this bitter and twisted Chaos Sorcerer is Nurgle's sworn servant and the master of the warband of Chaos Space Marines known as the Apostles of Contagion. His dark arts of necromancy can awaken the dead to a nightmarish half-life, unleashing the Zombie Plague of the Plague Lord upon friend and foe alike.
- Blight-Master Ussax - Ussax is a Veteran of the Death Guard, and known as a member of the inner circle of Chaos Sorcerers that serve the Daemon Primarch Mortarion. He is well known to the Ordo Malleus and to the Grey Knights, and has been responsible for countless millions of deaths throughout the millennia. Ussax is held to be one of the most darkly gifted concoctors of blights, afflictions and plagues serving the Death Guard, and his recent appearance in the warzones of the Jericho Reach, attended by a cadre of Plague Marines, is a cause for much concern amongst those with knowledge of his capabilities. According to recent findings presented to the Chamber of Vigilance of Watch Fortress Erioch, Blight-Master Ussax has been present in the Reach for around three standard years, travelling from one warzone to the next. At each battlefield, he gathers up a grim and unspeakable harvest from the dead and the dying, before returning to some as yet undiscovered fastness to concoct his latest ague. This he then unleashes upon the next battlefield he attends, once more harvesting the bodies of the victims. It is feared that the Blight-Master is refining his plagues, using the raging conflicts of the Jericho Reach as some vile breeding ground for new agonies to unleash upon an unsuspecting galaxy in Father Nurgle's name.
- Siegemaster Gremus Kalgaro - Gremus Kalgaro was a member of the Death Guard during the Great Crusade and Horus Heresy eras. A Marshal of the Legion, he held the position of Siegemaster, a commander of a Death Guard fleet, and Master of Ordnance following the death of Durak Rask on Istvaan III. A stoic commander who said little, Kalgaro commanded much of the Death Guard in the Battle of Catallus aboard the Endurance and served as Mortarion's right hand in the absence of Calas Typhon.
- Death Guard Lord and Siegemaster Vorx - Vorx was among the first Aspirants taken from Barbarus to join the Death Guard Legion after the Primarch Mortarion was rediscovered by the Emperor and given command of the XIV Legion. Vorx took part in many of the battles of the Great Crusade and eventually rose to become a Death Guard fleet commander, known as a "Siegemaster" within the Legion. When the Horus Heresy began, Vorx willingly joined his Primarch in turning upon the Imperium, for his loyalty was to Mortarion, not to a distant ruler on Terra. After the Warmaster Horus' forces were defeated in the Battle of Terra, Vorx fled with the other Traitors into the Eye of Terror in order to escape the Imperium's wrath during the Great Scouring. It was within the that Warp rift, at some unknown date, that he founded the Lords of Silence, which later become one of the Death Guard's most powerful warbands. After the opening of the Great Rift in the wake of the 13th Black Crusade, Vorx and the Lords of Silence allied with the Weeping Veil warband of the Word Bearers and attacked Sabatine -- the homeworld of the White Consuls Space Marine Chapter. Vorx and the Lords of Silence managed to not only defeat the White Consuls, but Vorx personally killed their Chapter Master Cymar Xydias before driving what remained of the Chapter off-world. Next, the Lords of Silence under Vorx's direction were able to disupt the Weeping Veil's attempt to claim the remainder of the world's population as sacrifices to bring three daemonic legions led by Greater Dameons to the world by transforming them all into Plague Zombies and Poxwalkers before the sacrifice could be undertaken. The Word Bearers departed the now-useless world, leaving the Lords of Misery to transform it into a Daemon World dedicated to the pursuit of all-new diseases and pathogens. In a short time, Sabatine had essentially become a veritable copy of Mortarion's own Plague Planet in the Eye of Terror. But Vorx remained uncertain about what should be his next course of action -- to remain on Sabatine and oversee its continued metamorphosis into another extension of the Plaguelord's realm into realspace -- or join with his Primarch in the great assault upon the Realm of Ultramar that became known as the Plague Wars.
- Captain Garstag - Garstag was a captain of the Lords of Silence warband and the commander of its Blightlord Terminator elite known as the Kardainn. He was recruited into the Death Guard from an Imperial Hive World some two thousand Terran years after the end of the Horus Heresy, an origin that constantly gnawed at Garstag's sense of legitimacy within the Legion, where most of the Heretic Astartes had come from Barbarus before the start of the Heresy. Garstag was often taunted by these members of the Legion because he had not been with them at the Battle of Terra or endured the Legion's other hardships. As a result, Garstag was hungry for more power and constantly sought opportunities to wrest power over the warband away from Vorx, who was fully aware of the open rivalry brewing with the Terminator.
- Dragan - Dragan was a high-ranking Plague Marine within the Lords of Silence, though he also had not been born on Barbarus or been a part of the original complement of the XIV Legion, having been recruited only 2,000 Terran years before the birth of the Great Rift. Dragan had originally been a Loyalist Space Marine who turned Renegade, but he can no longer remember anything about the events which surrounded his betrayal of the Emperor's cause. Like Garstag, Dargan is forced to constantly prove that he is the equal of the other Heretic Astartes within the warband. As a result of such ridiculous prejudice from his fellows, Dragan has come to grow contemptuous of all the ancient Primarchs, including Mortarion. Dragan is a proponent of a faction within the Death Guard that desires an immediate drive on Terra to overthrow the False Emperor, rather than first weakening the Imperium through different campaigns on its outlying worlds as Mortarion and his allies prefer.
- Slert - Slert is a Death Guard Biologus Putrifier. A twisted monstrosity like all of his kind, Slert is blind save for the dozens of mutant eyes that now exist across his body which can perceive disease and other organic abnormalities in others. He is in charge of all of the Lords of Silence's efforts at developing new diseases, toxins and plagues. Slert proudly maintains a collection of horribly mutated slaves and Plague Ogryns to test his latest ideas upon. Slert takes enormous pleasure in testing out his new contagions, often using them on the crew of the warband's warship, the Solace. He is not considered trustworthy either by Vorx or any of the other Plague Marines of the warband. It was Slert who, at the order of Vorx, assembled the arcane machinery needed on Sabatine to transform its remaining populace into Plague Zombies and Poxwalkers that would spoil the Weeping Veil warband's attempt to sacrifice them to the Chaos Gods.
- Philemon - Philemon is a Tallyman of Nurgle and a close political ally of Vorx within the Lords of Silence. Like most of the Plague God's Tallymen, Philemon is fatalistic and mathematically precise in his outlook on the galaxy. Within the Death Guard Legion's own internal politics he supports the position of Vorx and Mortarion that the Heretic Astartes should seek to weaken the Imperium in a number of different campaigns rather than immediately seeking to drive on Terra once more. In this he is staunchly opposed by other members of the Lords of Silence like Dragan and Garstag. Philemon took part in the attack on Sabatine, and warned Vorx against the planned treachery by their Word Bearer allies who sought to sacrifice who sought to sacrifice the planet's population to summon three Greater Daemons and their daemonic legions to the world, forever placing it beyond Nurgle's reach.
- Kledo - Kledo is a Plague Surgeon of the Lords of Silence who participated in the campaign to take Sabatine.
- Naum - Naum is a Chaos Dreadnought of the Lords of Silence who participated in the campaign to conquer Sabatine.
Just as the Death Guard have retained cohesion better than many other Traitor Legions, so they also maintain much larger and more organised fleets of spacecraft. These so-called Plague Fleets comprise ancient, Heresy-era Battleships, stolen Imperial warships, and even Space Hulks gathered from the tides of the Warp.
It falls to the warriors of the 6th Plague Company, the Ferrymen, to master and garrison these craft, and to liberate new ships that may be added to the Death Guard's rotting armada.
The Plague Fleets are vital to Mortarion's sons, for they are the vector by which the Death Guard spread Nurgle's blessings to the wider galaxy. Embarking onto these voidcraft, the Plague Companies ride the tides of the Warp like wind-blown contagion, emerging into realspace wherever Nurgle wills.
While their craft plough through the Immaterium, they fill up with thick clouds of revolting, fat-bodied plague flies that hatch from walls and bulkheads. When the Death Guard land upon enemy worlds or board their victims' spacecraft, these seething fly-storms come with them, spreading infection wherever they go.
Should ships of the Plague Fleets be lost or abandoned, they eventually find their way back to the Plague Planet as drifting derelicts to be crewed again. Some believe this is the will of Nurgle. Others claim that once a ship joins the Plague Fleets, its corrupted Machine Spirit is cursed to obey Mortarion until the end of time.
Although not as numerically large as the dedicated warfleets of certain Legions (notably the Imperial Fists, Sons of Horus and Dark Angels), the Death Guard possessed a high proportion of heavy capital ships, many of which were not only of considerable size and power but in several cases unique, being relics of the lost Dark Age of Technology.
The names of these vessel had entered into legend well before the Great Betrayal and would live on in infamy long afterward.
The following vessels were known to belong to the Legion fleet of the Death Guard before and during the Horus Heresy:
- Endurance (Gloriana-class Battleship) - The flagship of the XIVth Legion and the Primarch Mortarion during the Great Crusade and Horus Heresy.
- Indomitable Will (Capital Ship, Unknown Class) - Part of the XIVth Legion deployment charged with hunting down the White Scars Legion during the Horus Heresy.
- Lord of Hyrus (Capital Ship, Unknown Class)
- Moritatis Oculis (Capital Ship, Unknown Class)
- Plagueclaw (Capital Ship, Unknown Class) - The Plagueclaw was a vessel known to be present in the Death Guard's Legion fleet after they were corrupted by Chaos. It may originally have been a different vessel, even one of those named here, and been renamed after the Death Guard swore its allegiance to Nurgle.
- Spectre of Death (Capital Ship, Unknown Class)
- Stalwart (Capital Ship, Unknown Class)
- Tenacious (Capital Ship, Unknown Class) - The Tenacious was a heavy line-breaker that was lost in the first years of the Horus Heresy. Renamed as the Umaal, the vessel would nevertheless continue to fight under the colours of the White Scars Legion.
- Terminus Est (Capital Ship, Unknown Class) - The Terminus Est was the flagship of First Captain Calas Typhon and remains his vessel today now that he has become Typhus, a Chaos Lord and the Herald of Nurgle, though the vessel has become as twisted and unrecognisable as its master.
- Undying (Capital Ship, Unknown Class)
- Reaper's Shroud (Vengeance-class Grand Cruiser) - The Reaper's Shroud was the ship of Malig Laestygon, one of the XIVth Legion's Legion Commanders. The Reaper's Shroud was operating in the vicinity of the Realm of Ultramar - although why this was so remains a mystery. In league with Dark Apostle Quor Gallek, Laestygon set about chasing the Charbydis, a Salamanders' vessel ferrying the body of their fallen Primarch, Vulkan, back to their homeworld. The Reaper's Shroud was however unable to close with its prey before the Charbydis reached the Nocturne-system. Boarding the Charbydis in hope of seizing Vulkan's body, the boarding teams of the Death Guard discovered that the Primarch's casket had already left the ship, upon which Laestygon -- consumed by rage -- ordered the Charbydis's destruction. The Reaper's Shroud then conducted a full-scale planetary assault on Nocturne itself, after both conventionnal and virus-bombardment had failed. While the Death Guard forces planetside where entirely destroyed by the vengeful Salamanders, the Reaper's Shroud was confronted by two Strike Cruisers of the XVIIIth Legion she could ill-afford to do battle with, having been severely damaged herself by her encounter with the Charbydis. The Reaper's Shroud's ultimate fate remains unknown.
- Reaper's Scythe (Battle Barge) - The Reaper's Scythe was a Battle Barge of Mortarion during the Great Crusade. It is presently the capital ship of the Plague Fleet under the command of Plague Lord Scabarulous the Virulent.
- Dread (Battle Barge) - The Dread was originally the captured and renamed Battle Barge, Winter's Oath, seized from the Iron Hands Legion in the aftermath of the Istvaan V Dropsite Massacre. The Dread would be seen for the first time after its capture at the conquest of Dominica Minor, and go on to serve the XIVth Legion well for the rest of the Horus Heresy and beyond.
- Fourth Horseman (Battle Barge)
- Stalwart (Battle Barge)
- Mia Donna Mori (Battleship) - During the Great Crusade and the Horus Heresy this monstrous Battleship was a notable engine of destruction and carried enough Exterminatus-class alchem and bio-kill weaponry within her armoured vaults to end life in an entire sector if unleashed.
- Pitted Iron (Battleship) - Battleship class, commander unknown. Last seen in Ultima Segmentum.
- Morbid Revelation (Heavy Cruiser, Unknown Class) - The Morbid Revelation was boarded by Blackshield-forces in the Taracanis-system which succeeded in sabotaging the Revelation's Nova Cannon. When the vessel next tried to use its potent main gun against the Explorator Barque Radiant Precept, the Nova-shell exploded and the back blast crippled the Death Guard-vessel, forcing the Morbid Revelation to withdraw entirely from the war.
- Barbarus' Sting (Strike Cruiser)
- Implacable (Cruiser, Unknown Class)
- Necrotor (Gladius-class Light Cruiser) - The Necrotor operated closely with the Reaper's Shroud during the Horus Heresy, acting as a scout vessel for the far heavier ship. It was the Necrotor which first encountered the fleeing Charbydis as their assault on a fuel dump compelled the Salamanders to intervene. Shadowing the Charbydis' movements, the Necrotor assaulted the far heavier Battle Barge after the Charbydis had lost power and weapons through its emergency retranslation into realtiy. While the boarding action met initial success -- the Charbydis numbering only sixty-six able-bodied Legionaries, the Necrotor was mercilessly destroyed when the Battle Barge retrieved power and weapon functions. Cut-off and sourrounded, the boarding parties also perished to the last man.
- Eisenstein (Frigate) - The Eisenstein was destroyed in the course of its famous flight to bring word of the Warmaster Horus' betrayal to the Emperor on Terra at the direction of Nathaniel Garro.
- Greenbottle (Escort) - The Greenbottle belonged to an unknwon Escort class. Despite its relatively small size, the Greenbottle has proven able to slip through defences to release orbital virus bombardments on several Imperial Hive Worlds to devastating effect.
- Valley of Haloes (Supply Hauler) - The Valley of Haloes was a supply hauler in service to the XIVth Legion during the Great Crusade. Suffering a dangerous Gellar Field fluctuation while in transit to the Death Guard's 6th Company flotilla at Arcturan, the Valley had emerged from the Immaterium to effect emergency repairs. Unfortunately, the Valley of Haloes was a casualty at the Arcturan engagement, lost with all hands. Fortunately, a distress signal and recording of the outbreak of insurrection against the Imperium within the Istvaan System was received and was conveyed to the Terminus Est before this regrettable loss, initiating the sequence of events that would become known as the Istvaan III Atrocity.
- Solace (Repulsive-class Grand Cruiser) - When this warship's hull was originally laid down in the 34th Millennium on the Forge World of Lashte, it was named Undying Valour. It entered service with Battlefleet Archon less than a Terran year after structure completion, commanded by an inexperienced captain named Lutrecia Prask. Its complement of more than thirty thousand ratings was largely drawn from Imperial Navy levy stations strung out beyond the Mourn Ring, and was graded as competent by four subsequent inspection visits. Like all the original Corinus-class Grand Cruisers, it was heavily armed, with Lance and Macrocannon arrays out of proportion to its relatively underweight Void Shielding. It transpired that the class gradually fell out of favour with Imperial commanders, though the Undying Valour served with distinction for another five hundred Terran years, gaining a kill ratio marginally higher than its reputation indicated likely. Captain Prask died in an engagement less than twenty standard years after assuming command, and was replaced by a succession of captains promoted from the lower decks. A Grand Cruiser was a world of its own, and only the very greatest Battleships regularly recruited senior officers from outside the hull -- most captains were born, raised and trained on the ship they would later command. The last of the line, Orthan Hemmo, was of this tradition, and was said to have loved the ship more than his own children, of which there were twenty before circumstances intervened to curtail his commendable contribution to the replenishment of Imperial numbers.Those circumstances came at the Battle of the Borghesh Channel, a vicious encounter in which the Imperium lost twenty vessels and had its grip loosened on three sub-sectors. By the time Imperial Navy retribution fleets overwhelmed the region more than sixty standard years later, there was no sign of the Undying Valour at its last reported coordinates -- only a slowly spinning core of metal to which Captain Hemmo's deep-frozen corpse was, it was rumoured later, nailed on tight. In truth, the Undying Valour had been taken into the Eye of Terror and stayed there for five Terran millennia. It was renamed the Solace after it became corrupted by the power of Nurgle, which made the ship semi-sentient. It was eventually taken by the Chaos Lord Vorx, commander of the Heretic Astartes warband of the Death Guard called the Lords of Silence, who ensured that the corrupted ship was placated with plenty of flesh and blood, in order to prevent the Solace from turning upon its own warriors. However this did not stop the Solace from occasionally growing tentacles in order to attack and devour members of the warband.
- Books of Woe - Within the mouldering libraries of his Black Manse on the Plague Planet, Mortarion hoards endless treatises and forbidden tomes of numerology, cryptoscience, abhorrent scripture and arcane conjuring. The foulest of these are the seven Books of Woe, aberrations whose covers drip with filth and whose pages moan like a bloated corpse when turned. On occasion, Mortarion bestows one of these abhorrent tomes upon a favoured champion so that they may call upon the incantations within. By reading from a Book of Woe, a worthy champion may tear aside the veil of reality and summon the Plague God's daemon legions into reality. They can draw the Garden of Nurgle itself into realspace, and -- during cursed stellar conjunctions -- even transform planets into befouled hellscapes, worlds of Nurgle manifesting in reality like sores upon a sick man's body.
- Dolorous Knell - The clangour of this giant bell is painful to the ear, almost intrusive as its foul sounds push their sickening notes into the minds of those nearby. Each toll registers as a dull clank on the data-harvest of recording devices such as vid-thief skulls, but to hear it in person is quite another matter. Bravery is undone and certainty ebbed away as the shambling horde of the Death Guard closes in, rendered as looming behemoths by the peals of the deathly knell.
- Pandemic Staff - This rune-engraved artefact is long and pitted, mouldering with a visible miasma of plague and entropy. Every one of its odd dents and holes harbours a deadly strain of contagion, one of Nurgle's old favourites, tried and proven. Collectively, the grotesque diseases that riddle the Pandemic Staff have seen trillions of lives ebb away to nothing, reduced to little more than fodder for the Grandfather's Garden. When waved expansively, the staff can conjure forth a tide of hypertoxic fluids that could bring low even a rampaging Pestigor.
- Plaguebringer - The hooked blade Plaguebringer once bore the souls of a trio of Beasts of Nurgle. Once, the sword sprayed the virulent, infected spittle of these overexcitable daemons with every swing. However, those entities were trapped so long in the rusted artefact's confines that their lethally potent enthusiasm has drained away, replaced with something even worse. After a long period of sulking, the blade's inhabitants became something else entirely; it now contains the malignant souls of three Rot Flies that take every chance to inflict a terrible wasting disease on those around them.
- Plague Skull of Glothila - This oversized death's head was once the skull of the Chaos Lord Glothila, whose dying wish was to become a weapon of purest evil.
- Poxwalker Hive - Daemon insects spill from the tubular, chimney-like structures of the Poxwalker Hive. The incessant droning chatter of these tiny creatures acts as an infection in its own right, and those who willingly listen to it are at grave risk of contracting the Poxwalker's Curse. Should they succumb, they will devolve into shambling, mutant monstrosities, murmuring and babbling in the same flyblown tongue as the hive itself.
- Puscleaver - Appearing as a particularly large Plague Knife, more like a machete than the traditional side weapon of the Death Guard Legion, the Puscleaver bears the infamous Gurgling Doom contagion. One struck by the blade has not only to contend with part of their anatomy being hacked away, for its edge remains punishingly sharp, but also a wound so infected it balloons into a swollen mess in seconds. The afflicted individual keels over a moment later, gurgling phlegm as he finally realises the glory of Nurgle's generosity.
The Chaos Space Marines of the Death Guard often wear the antique Mark III Iron Pattern of Power Armour as it was particularly useful in providing enhanced protection in the toxic environments that the XIVth Legion preferred to fight in.
As the Dusk Raiders, the XIVth Legion's armour was an unpainted storm grey. The entire right vambrace, gauntlet and shoulder plate (sometimes both) were painted the deep crimson of drying blood, which signified the XIVth Legion's status as the "red right hand" of the Emperor's justice.
After their Primarch Mortarion took command of the XIVth Legion, the newly redubbed Death Guard began wearing ivory-grey unpainted ceramite, save for a few murky-jade coloured markings.
Pre-Heresy Tactical Markings and Heraldry
- Death Guard Helm Variations - The use of vertical helmet stripes to denote seniority is believed to have originated with the Legion's re-organisation as the Death Guard, and became common as a mark of veterancy and tactical command.
- Death Guard Legion Armour - Battle damage that did not compromise a Legionary's Power Armour systems was retained as a mark of honour by Death Guard Astartes.
After their acceptance of Nurgle as their patron, the Death Guard's armour has taken on a sickly green appearance. Plague Marines are known for having many boils, sores, and open wounds visible on their bodies, and the more mutated often sport tentacles or the trademark single horn commonly seen on daemonic minions of Nurgle.
The helmets of Plague Marine Power Armour often resemble old-fashioned gasmasks, particularly those of Russian or German make during the two World Wars, in reference to the poison mists of Mortarion's homeworld, Barbarus.
Mortarion, with his pale skin, huge scythe and hooded robes, bears a great resemblance to classical representations of the Grim Reaper, the embodiment of Death himself.
The uniforms and heraldry of the Death Guard are redolent of disease and decay. From the vectoriums of the Plague Companies to divergent Plague Marine warbands that long ago broke from their parent Legion, all can be easily identified by the filth that encrusts their armour, the rot and rust that clings to them, and the foul Nurgle iconography emblazoned on their heavy plate.
Ever since the last days of the Horus Heresy, the Death Guard have retained their uniform colours of leprous green and verdigrised brass. Though many of the Legion's vectoriums have adopted their own foul panoply, vast swathes of the Death Guard still march to war clad in these same grim hues.
The tri-lobed rune of Nurgle and the sigil of the Plague Fly can be seen much in evidence on the armour of the Death Guard Legionaries, proclaiming their allegiance to the God of Plagues and their dedication to spreading his vile contagions.
The Dusk Raiders' Legion badge was a black skull halved, with a setting black sun on the other side, centred on a field of deep crimson.
This icon symbolised the XIVth Legion's original given epithet of the "Dusk Raiders," a consequence of their use of the ancient tactic of conducting major ground attacks at the fall of night.
Once the Dusk Raiders were unleashed upon their foes, nothing would stay the Legion's hand.
After the Heresy, when the Death Guard accepted the Plague Lord as their patron Chaos God, the Legion has chosen to wear multiple different variants of the Mark of Nurgle, or a corrupted version of the original Death Guard badge, as their new Legion badge.
