A Chaos Lord is one of the most powerful of the Champions of Chaos who often serves as the commander of a Chaos Space Marine warband and the other Forces of Chaos. A Chaos Lord is usually, though not always, a Heretic Astartes himself. They are not necessarily those who rose through the ranks properly in a hierarchical fashion, but are often those most blessed by the Chaos Gods or simply the most powerful or charismatic individuals among the Forces of Chaos.
The greatest of the Champions of Chaos become Chaos Lords and are often granted hideous mutations and physical alterations by the Ruinous Powers to further their cause. Chaos Lords are so powerful as to be able to bind the other Forces of Chaos to their will, although this often brings a dangerous position as advancement among the Forces of Chaos is commonly achieved through the death or murder of another Chaos Lord or Champion.
Some Chaos Lords lead through brute strength, others through cunning and some are maniacs bent solely on self-aggrandisement. Others are true-believing worshipers of Chaos and possess a zealous dedication to the cause of the Dark Gods.
A Chaos Lord is ultimately always a tyrannical warrior-king who lives to bathe in the blood of worlds. He strives to bring whole star systems to their knees in the name of his patron deities. Typified by merciless ambition and fierce pride, many of these champions of disorder were once noble Chapter Masters and Captains of the Adeptus Astartes, but long Terran years of unremitting war have twisted their souls beyond recovery.
It takes a being of exceptional willpower and personal magnetism to unite the warbands of Chaos Space Marines lurking in the Warp, and even then, a would-be warlord cannot be everywhere at once. Only those marked for greatness by the gods themselves can claim support from Heretic Astartes, mortals and daemons alike.
All Chaos Lords are imposing in stature. In the case of Chaos Space Marines, their genetically-enhanced transhuman physiques have been made even more impressive by the protean caress of the Warp. Their wargear is often as outlandish as their physical appearance; a Chaos Lord may hack his foes apart with a massive Chainaxe, blast them with an ancient Combi-weapon, or slice open their vehicles with a screaming Daemon Sword.
Regardless of affiliation, these conquerors of worlds invariably prefer to lead from the front. There, the visceral thrill of war is strong enough to eclipse any glimmering sense of betrayal they may feel as they rend their Loyalist brothers limb from limb.
Possessed of a wrath so intense it often clouds their vision, the Lords of Khorne lead by example. Each Chaos Lord is a looming brute in gore-stained armour. Many such lords retain their intellect and conqueror's instincts, but their blood-greed is so strong that, upon the battlefield, they could easily be mistaken for mindless savages. It matters little, for so frenzied are the warriors that follow them that they are lost to reason; for lord and follower alike, only the sight of blood holds sway.
Tzeentch grants his lordly devotees access to an almost limitless supply of sorcerous power. Such beings have a supernatural ability to outguess their foes. They often manifest arcane mutations such as haloes of dark flame, third eyes or crystalline bodies, whilst mystical auras protect them from harm, transmuting attacks into harmless energy. Their plans are so labyrinthine that only the insane may even begin to understand them.
The lords of Nurgle are lumbering, filth-encrusted hulks that devote their lives to spreading disease across the stars. Their guts are bloated sacs of putrid gas and rancid fat, and their sagging skin has the waxy pallor of a corpse, but their resistance to injury is legendary. These devout sons of Grandfather Nurgle revel in their foulness, leading Heretic and daemon alike to war.
Chaos Lords of Slaanesh are gifted with strange sensory organs and mood amplifiers that allow them to better savour the shocking stimuli of open warfare. The life of such a lord is a whirlwind of excess that inspires his followers anew with every battle. His mind reacts so swiftly that he can fight with blurring speed and dexterity in the pursuit of ever-greater sensation -- and the pleasure it brings.
Mark of the Chaos Champion
Chaos Champions often bear upon their flesh the Mark of one of the four Chaos Gods or of Chaos Undivided. Champions of Khorne are berserk savages and value physical strength and direct melee combat over cunning and strategy. Tzeentch's Champions are very knowledgeable on a wide array of matters and many are Chaos Sorcerers.
The Champions of Nurgle are the most distorted and physically corrupted of Chaos' followers, their bodies dulled from the constant pain of the diseases they bear, enabling them to endure extreme physical injury with little trauma. Slaaneshi Champions are those who seek out the most intense sensory experiences possible due to the extraordinary pleasure this provides them. They are physically the fastest warriors of Chaos due to their hyper-sensitive minds and often surgically-altered or mutated reaction times.
Adharon was a former Space Marine Captain of the Sons of Guilliman Chapter. He was corrupted by Chaos and gathered a warband of like-minded corrupted Astartes around himself from his former company to raid and pillage the commerce of the Imperium of Man in the name of the Dark Gods. The Siege of Vraks represented the first time that his warband, named Adharon's Reavers, had operated in concert with other Chaos Space Marine forces.
Agrand the Annihilator
A Chaos Lord and notable Chaos Space Marine Biker, Agrand led hordes of Khorne Daemonkin against the Tau Empire colony of Ral'eth, slaughtering all in their path, as they smashed the Tau Hunter Cadres lines. Soon enough, with their forces reeling, the main Daemonkin forces were able to push forward, finally overrunning the cornered Tau and adding their skulls as prizes for the Skull Throne of Khorne.
Ahzek Ahriman is a Chaos Space Marine and the most powerful Chaos Sorcerer of the Thousand SonsTraitor Legion after their Daemon PrimarchMagnus the Red himself. Ahriman seeks to gain entry into the Black Library so that he might better comprehend the nature of his patron Chaos GodTzeentch and of the force of Chaos itself and gain the unrivalled power such knowledge will bring. His action in crafting the Rubric of Ahriman, perhaps one of the greatest works of sorcery in history, would ultimately result in his banishment from the Legion he had hoped to safeguard. He remains a wanderer across the galaxy, forever seeking out any knowledge that will allow him to finally grasp the greatest of all enigmas in the galaxy -- the true nature of Tzeentch himself. At various times during his wanderings, Ahriman has served as a Chaos Lord for both the Brotherhood of Dust and the Prodigal Sons warbands.
A powerful Chaos Lord and Noise Marine of the Emperor's Children Traitor Legion, Emmesh-Aiye might not have been an original member of the IIIrd Legion, as he could no longer recall his origin. Nevertheless, he was a notorious raider and degenerate. Sometime in the 41st Millennium, Emmesh-Aiye was among those who accepted the invitation of Chengrel of the Iron Warriors to take part in an auction for possession of captured EldarSpirit Stones, the winner decided by their tales of destruction and conquest. A free-for-all battle eventually ensued as the vying Chaos Lords fought one another for possession of the stones. After slaying Hodir, a Chaos Lord of the Night Lords for possession of the stones, Emmesh-Aiye battled Chaos Lord Khrove of the Thousand Sons. However the Chaos Sorcerer used his innate psychic abilities to turn the ground Emmesh-Aiye and his slave-warriors stood on into a bottomless pit of quicksand-like metal. Trapped, Emmesh-Aiye sunk into the hole and died.
Warsmith Andraaz was an Iron Warriors Warsmith of the 3rd Grand Company. Following the Traitor Legions flight to the Eye of Terror at the end of the Horus Heresy, he eventually rose in favour to command the Fortress World of Castellax, a former Imperial Mining World, whose population was enslaved in order to provide manual labour to produce materials for the Daemon World of Medrengard. Sometime during the 41st Millennium, Medrengard was invaded by OrkWarboss Biglug and his WAAAGH!. Andraaz suffered an inglorious and undignified death at the hands of the Ork Warboss.
Vandred Anrathi, known later as "The Exalted," was a Captain of the 10th Company (Chaos Lord) of the Night Lords warband of The Exalted. Vandred is a Chaos Champion of Tzeentch. Allying himself with Abaddon the Despoiler, he allowed himself to be possessed by a Daemon. Before accepting the daemon which would come to dominate him, Vandred was an honored warrior, but his true forte was void combat. After his change into the Exalted, he became even more focused on void combat. When the Exalted made a deal with Red Corsairs Renegade warband to assist them in a military campaign against Vilamus, the Exalted plotted to steal an ex-Night Lords vessel back from the Red Corsairs. During the subsequent battle the Exalted's body was destroyed at its foul soul was banished back into the Warp.
Arkos the Faithless, also known as the Scion of Alpharius, is the Chaos Lord of the Alpha Legion warband known as The Faithless. Since the Horus Heresy, this vile Chaos Lord has continued the Long War against the "Corpse Emperor" and his unwitting servants. Arkos continued to stir up dissension and rebellion within the realm of Mankind until he met his eventual fate during the Siege of Vraks late in the 41st Millennium. Confronted by a strike team composed of Loyalist Astartes drawn from the Angels of Absolution and the Dark AngelsChapters, it is believed that Arkos was eventually captured and brought back to the Dark Angels' mobile fortress-monastery, The Rock, as a prisoner. His actual fate remains unknown.
Baldarun is an Iron Warriors Warsmith, commanding a Grand Battery. Exiled from his Legion since a previous defeat against rival Warsmiths on Medrengard, Baldarun has been seeking the means to rebuild his standing. Seeing an opportunity to do so, he took part in The Scouring of Makenna VII. He became leader of the Renegade warband the Abrial's Claw after making a pact with a well-known renegade Abrial Shard. In exchange for his men, Baldarun will share with him the secret of his beloved techno-virus.
Bale was the Chaos Lord who brought the Ruinous Powers of Chaos, in the form of his Alpha Legion warband, to the world of Tartarus. He was pursuing the Chaotic artefact known as the Maledictum for himself, and to better serve the goals of the Chaos Gods. Bale was an unusual Alpha Legion commander in that he much preferred a brutal and frontally aggressive combat doctrine rather than the subtle manipulation that was more in line with the modus operandi of the Alpha Legion. Bale was slain by Blood Ravens Captain Gabriel Angelos.
Heinrich Bale is a Chaos Warmaster, known to have been a former disciple of the Young School (formally known as the Gareox Prerogative -- a group of young Imperial Navy officers in the 36th Millennium who sought to radically redefine Imperial Navy doctrine), before his fall to Chaos. It is widely believed that Bale sought to combine the hard-hitting lances of the Desolator-class Battleship with the versatility provided by attack craft, ultimately resulting in the Desecrator-class Battleship. It is unknown how Bale managed these extensive modifications, but his flagship, The Treacherous, proved to be a menacing foe during the Gothic War.
Barkor the Bloody
In the 33rd Millennium, the Chaos Lord known as Barkor the Bloody took the Scriptures of Slaughter from the Infernal Maze and forged the first warband of Khorne Daemonkin known as the Skullsworn. For over a century, he led his followers on a violent rampage across the stars, depopulating more than a dozen worlds before he found his ascension as a Daemon Prince on the plains of Ossedor II.
Berrosus was an Iron Warriors Warsmith of the 2nd Grand Battalion. During the Battle of Phall he had the misfortune of bringing ill-favoured news to Perturabo, and was critically injured by the enraged Primarch. On the orders of his Primarch, Berossus was eventually encased within the shell of a Chaos Dreadnought to be tormented across the centuries. By the 41st Millennium, Berossus and fellow Warsmith Toramino, were angered over Warsmith Honsou's refusal to share captured Imperial Fistsgene-seed that was stolen from Hydra Cordatus during the 13th Black Crusade, and so declared war against him. During the ensuing battle, Berrosus was slain by Honsou's life-ward, Onyx, who managed to breech Berrosus' Dreadnought carapace. Honsou then reached inside the Dreadnought shell and ripped out its Mind Impulse Unit and pulped Berrosus' head before all to see.
Fabius Bile was once the Chief Apothecary of the Emperor's ChildrenTraitor Legion, who has repeatedly attempted to use his knowledge of cloning and genetic engineering to create superhuman beings under his control in a quest to match and then exceed the Emperor of Mankind's original scientific achievement in creating the superhuman Legiones Astartes. Travelling the galaxy more widely than any other Chaos Lord of the Traitor Legions, Bile has earned a number of epithets and aliases from those who have suffered the affects of his vile experiments. To Bile himself, there is only one title that does his magnificence justice -- the "Primogenitor". He believes that in him is the Emperor's boundless artistry reborn. He claims he has unlocked the secrets of the Emperor's earliest replicae experiments during the creation of the Primarchs and the first Space Marines. Bile's twisted alchemical knowledge and skills at genetic manipulation can be attested to by every planet he has had contact with, for he has left a trail of foul deviants and twisted abominations wherever his ships have landed. His name has become a curse to the High Lords of Terra and those of the Apothecarion who have learned of his legend.
Roghax Bloodhand is a World Eaters Chaos Lord who has sworn to collect a skull from every warrior species in the galaxy and offer them to his patron lord, Khorne.

Borroleth was a former Legionary of the Dark AngelsLegion who had fallen sway to the Arch-Heretic Sars Luther. When Caliban broke apart during the confrontation between Primarch Lion El'Jonson and Luther, Barroleth was swept away into the warp and would have been lost. Nurgle answered the lost legionary's prayers, and in that moment, Borroleth swore his eternal servitude. For a time, the Fallen Angel led the Chaos warband known as the Children of the Merciful Lord, and was responsible for the attacks on the Imperial world of Cordassa in the 41st Millennium. He was eventually slain by Artemius Grohm, an Interrogator-Chaplain of the Dark Angels Chapter.

During the Horus Heresy, he was known to have taken part in the Siege of the Imperial Palace during the final epic campaign of the Battle of Terra. Millennia of battling the Imperium had taken the toll on his body, which was heavily augmented by bionics and mechanical replacements. By the 41st Millennium, his remains were housed in a custom-built massive four-legged Dreadnought. Chengrel is noted to having burned the Imperial Hive World of Heggoru, a world under the protection of the Imperial Fists, a Chapter Chengrel despises like most Iron Warriors.
Constantinus, also known as Constantinus the Liberator, was a former squad Sergeant of the Sons of Guilliman Chapter's 4th Company who turned to Chaos.

For three years Constantinus led his squad on endless patrols through the caves of Nova Terra, cleansing planet of remaining pockets of Tyranid infestation. When rumor arose of a Genestealer infestation among the city of Cirtus' ruling aristocracy, Constantinus hunted down the infected nobles and their families brutally. However the people of Nova Terra were enraged by the summary execution of their leaders and rose up in revolt. Disgusted by this "ungrateful" behavior and his will exhausted, Constantinus burnt down entire sectors of Cirtus, turning on those in his own squad who tried to stop him. He appeared before the crowd and announced himself the new ruler of Cirtus declaring the Emperor and his minions had turned him into such a monster. He led Nova Terra in a rebellion and subsequent costly and drawn out war against the Imperium of Man, known as the Constantinus Iconoclasm.

Eleaxus, also known as Eleaxus the Flawless, is a devout Chaos Champion of the Pleasure God and the leader of The Flawless Host. Eleaxus cares for nothing more than his own glorification and the furtherance of his desire to sit at the right hand of Slaanesh, damning himself further by partaking in blasphemous feasts after his victories. With the promise of all the luxuries of the Imperial world of Makenna VII, Eleaxus' fealty was bought by Warmaster Davroth of the Word BearersTraitor Legion, to help him conquer the doomed world.

"The Headsman" is one of the most brutal of all of the World Eaters Chaos Space Marines known to be active in the Jericho Reach.

Gallus Herodicus was once the Chapter Master of the Seekers of Truth Chapter of Space Marines who were closely allied with the Inquisition and often did the Ordos' bidding.

The injustice was slowly draining the Seekers' morale, and in the night, Herodicus prayed to the God-Emperor for a way to know when a man was lying. Unfortunately, the Chaos GodTzeentch was listening and granted his prayer. From that moment, Herodicus and his Astartes could hear every lie spoken by the mouths of Mankind. The Chapter went rogue and became a warband of Chaos Space Marines dedicated to the Lord of Change within only days of receiving their new "gift", and Herodicus is now the powerful Chaos Lord who leads the Scourged in an attempt to purge the galaxy of the False Emperor and his irredeemably corrupt Imperium.

Honsou is a Chaos Space Marine and a Warsmith of the Iron WarriorsTraitor Legion.

Once the Captain of the Sons of Malice's elite 1st Company, Kathal was granted the honour of leading the Chapter in its victory rites after the successful Cilix 225 Campaign.

Khrove is a Chaos Sorcerer Lord and warlord of the Thousand Sons. Unlike many of his Chaos Space Marine colleagues, Khrove was not an original member of the Legiones Astartes or a veteran of the Horus Heresy. Rather, he worked as a scholar on the Imperial world of Prekae Magna and collected much arcane and rare knowledge which was eventually stolen by Ahriman, who kidnapped Khrove and inducted him into the Thousand Sons after brutal training and genetic enhancement. Khrove was one of many Chaos Lords invited by Warsmith Chengrel of the Iron Warriors to bid for the possession of captured AeldariSpirit Stones. Chengrel became enraged when he learned none of the invited Chaos Lords were original veterans of the Long War, and a free-for-all ensued for possession of the stones.

Madox was a notable Chaos Sorcerer of the Thousand Sons who led several plots to destroy his Legion's ancient foes, the Space Wolves Chapter. He reserved a special hatred for the Wolf LordRagnar Blackmane, who has foiled several plots when they confronted one another across several decades of the late 41st Millennium. It is presumed that he was finally killed on the world of Charys, where Madox hoped to enact a Chaotic ritual to fully corrupt the gene-seed of the Space Wolves and set them on the path of damnation. The ritual used to enact the Chaos Sorcerer's blasphemous ritual was interrupted by the timely intervention of Ragnar Blackmane and his fellow Space Wolves. Many decades later, while suppressing a Chaos rebellion on an unnamed world, Ragnar Blackmane heard rumours that the sorcerer Madox was still alive and leading the Forces of Chaos. Though unsure if the rumours were true, it could be likely that Madox had indeed been resurrected through malefic means, as he has done so in the past by using the body of a Chaos Cultist. If this is indeed true, then Madox may truly never die, and eventually he could once again return to the material realm.
Following the tragic events of the Horus Heresy, during the unending bloodshed of the Great Scouring, the Traitor Chaos Warlord Dynat Mal, known as "Crowbane" for his ambush and slaughter of Raven Guard forces during the Battle of Lyx, flees to the Mandragoran Stars and gathers to him a coterie of Renegades, diabolists and Traitors thousands strong. Imperial forces sent in pursuit are repeatedly out-manoeuvred and cut apart piecemeal as Dynat's forces, now known as "The Shadowed Ones", employ guerrilla tactics and dark forces to extend their mastery over the region. After the vital Imperial outpost station at the world of Amarah in what is now the Orpheus Sector of the Segmentum Tempestus is attacked and destroyed, its entire population slaughtered and stockpiles plundered, any Imperial claim to the region is effectively severed. This sundered realm, caught beyond the light of the Imperium at the edges of the Veiled Region, becomes known as the Dark Marches and is benighted by ignorance and discord, and is shrouded from human sight. In 170.M32, the Raven Guard returned to the Dark Marches in force to exact their vengeance on Dynat Mal, but found his domain to be devoid of life and his Cruiser Occam's Razor in ruins on the Jungle World of Apollyon.

High Magister Mordeghai, a gifted Chaos Sorcerer, was a Tribune Senioris to Magnus the Red at the Siege of the Imperial Palace during the epic Battle of Terra. Sometime during the 41st Millennium, Mordeghai had foreseen that if his Death Guard arch-rival Festardius gained control of the world of Makenna VII, the Plague Lord would use his new influence to turn Mortarion's legions against Mordeghai's cabal. The best way to prevent this from happening was to wrest control from Festardius once the Warmaster Davroth had departed. Mordeghai believed he had more than enough Thousand Sons Rubric Marines at his disposal to accomplish this.

When the Emperor found Lorgar on Colchis, Kor Phaeron was too old to undergo the full implantation process to become a a full-blooded Space Marine, but so favoured was he in the eyes of his Primarch that he received the most potent of biological augments it was possible to bestow upon a man short of elevation to the Legiones Astartes, and was declared First Captain of the Word Bearers Legion. Scorned by many in his Legion as "half Astartes", Kor Phaeron nevertheless had the ear of the Primarch and, more than any other individual, is responsible for the corruption of his Primarch and the Astartes of the XVIIth Legion into repudiating their oaths to the Emperor of Mankind and becoming willing pawns of Chaos.
Phocron was a name given to a supposed Alpha Legion Chaos Lord. Traveling across the Imperium, Phocron was responsible for the deaths of entire worlds through acts of sabotage, war, and terrorism undertaken by his vast network of Cultists and agents. Pursued by an unnamed Ordo Hereticus Inquisitor for nearly a century, in the end the Imperium discovered his hideout, the derelict space station and Space HulkHydra's Eye. However, despite taking the station and cornering Phocron, the Inquisitor was shocked to find that "Phocron" was an identity and alias used by many Alpha Legion members. There had never been a true Phocron, it was merely a name to organize cultists and agents across the Imperium. Moreover, now that the identity was compromised the Alpha Legion had decided to discard the identity anyway. Worse still for the Inquisitor, a member of the Alpha Legion had made his face identical to his own, indicating that he was the new identity to replace Phocron.
Potchek was a Chaos Sorcerer and Chaos Lord who in 551.M37, organized a warband of Traitors and Heretics, Mutants, and summoned Daemons, launching an assault on the Imperial world of Persembe, resulting in the Battle for Kurin's Acropolis.

When the Warsmith Honsou was successful in obtaining a large stock of gene-seed from the hated Imperial Fists on the world of Hydra Cordatus, Toramino and his Grand Company wanted their promised share of the precious genetic material required to swell their numbers. When Honsou reneged on the deal and kept all of the gene-seed for his own Grand Company, Toramino declared war against his wayward comrade.

He rules the greater portion of the Death Guard's armada from the bridge of his flagship, the Terminus Est, a warship encrusted with the filth of aeons that was ancient even when the Horus Heresy began some ten thousand standard years ago. His skill in ship-to-ship combat has been honed over many millennia of war, and when he broods in his command throne upon his starship's bridge, he and the titanic war machine become one. Though the warship exists on the cusp of Imperial legend, its three-pronged pict-sign is dreaded by admirals and Planetary Governors alike across the Segmentum Obscurus. Wherever Typhus' flagship appears, it heralds plague, death and misery on a system-wide scale. Even whispers of its coming can cause panicked evacuations from worlds in its path, for wherever Typhus goes, pain and despair blossom in his wake.

With his warband, the Clysm, the World Eaters Chaos Champion had fought on a thousand worlds, butchering human and alien alike in the name of wanton carnage and murder, bringing glory to Khorne’s name through the prosecution of Blood Crusades, the slaughter of Slaanesh's perverse followers and the collection of skulls on an obscene scale.

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 what he is capable of.
Karrad Vall’s name is a dark curse on those who have ventured into the Koronus Expanse. No one has ever seen him, but the barbed prows of his ships and the baying of his scarred warriors are enough to have caused captains to scuttle their craft rather than be taken before Karrad Vall, the Faceless Lord. Some whisper that Vall was once an Adept of the Munitorium, a former tithe-master swayed and fallen to the lure of the Dark Gods, whilst others claim he was once a trusted admiral of Battlefleet Calixis. What is known is that Karrad Vall braved the Maw in 794.M41 and promptly established his intent by shelling Footfall and engaging Calligos Winterscale in battle.

Vanneus was once a loyal Space Marine Epistolary of the Lectors of Ixis Chapter. The exact circumstances under which Vanneus chose or was compelled to embrace the Chaos God Tzeentch remain a mystery. It is likely that in fulfilling his duties as a psyker and projecting his mind through the Immaterium, he fell victim to one of Tzeentch's servants residing there. Whatever the circumstances may have been, it is known that Vanneus denied the Emperor, rejected his former identity, took the name Amadeus Volkstein, and now serves Tzeentch as a powerful Chaos Sorcerer. He currently leads the warband of Chaos Space Marines known as the Oracles of Change.
Svane Vulfbad was a RenegadeWolf Lord of the Space WolvesSpace MarineChapter.

Wolf Lord Harald Deathwolf and his Great Company were charged in 913.M41 by the Great WolfLogan Grimnar to track down and execute the notorious Traitor. Deathwolf and his company eventually uncovered Vulfbad in the Cliedes System, tracking their elusive quarry to the storm-wracked moon of Gallimius. After weeks of stalking their prey, Deathwolf's hunting party cornered Vulfbad atop a dust-crowned mountain just as the vile Traitor was completing a sorcerous summoning ritual that would have seen his traitorous forces thronged with daemons. The Renegade Space Wolf fought like a madman even after his allies had been slain, badly wounding Harald's Thunderwolf in the process, but he was ultimately outmatched. As Harald brought his axe around to deliver the deathblow, a bolt of lightning struck them both. When the dust settled all that remained of Vulfbad was his Frost Axe, a shard of which now juts from the cybernetic jaw of Harald's Thunderwolf.

Zagthean, known as Zagthean the Broken, is a Chaos Lord of the Black Legion. He led his Black Legion warband in a fury of violence and excess on the Agri-World of Valesia. For his own satisfaction, the Warlord constructed a vast maze of thorns from the world's rose orchards, blinding his prisoners and loosing them within its tunnels, before hunting them down at his leisure. Countless inhabitants spent their final terrifying hours listening desperately for the sounds of pursuit, their flesh bleeding from dozens of thorn cuts.
Zhorisch is an ancient master of scientific and technical pursuits as well as a cunning practitioner of the art and science of siege warfare. Warsmith Zhorisch was a member of the original Iron Warriors Legion raised up by Perturabo, and he was initially a pre-cursor of the modern Techmarine, a highly trained fighting engineer. As the IVth Legion slowly fell into bitterness and treason, he gleefully followed his leaders into rebellion against the Emperor. Over the millennia following the Horus Heresy, he rose in power with guile and cunning, eventually reaching the rank of Warsmith and leading his own warband. As a Warsmith, he developed his well-known lust for hidden knowledge, leading many a campaign of terror against unsuspecting Imperial worlds in pursuit of secrets both academic and technological. When he was given the chance to take the Obsidian Forge at Imbru, located in the Jericho Reach, and loot what he believed to be a treasure trove of Imperial secrets, he immediately accepted the task.
Zhufor, also called Zhufor the Impaler and the Butcher of Vraks, is the Chaos Lord who lead the warband of World Eaters' Chaos Space Marines named the Skulltakers during the Siege of Vraks. Zhufor was not always a servant of the Dark Gods. Once, millennia ago, he was known as Balzach, a former Sergeant of the Storm Lords Chapter. During the sacking of the hive cities of Paramar, Sergeant Balzach was severely wounded and taken captive by the Traitor Marines of the World Eaters Legion. Balzach was then drugged and subjected to torture and psycho-corrective surgery to alter his brainwave patterns in order to break his Imperial indoctrination. He was turned into a raging psychopathic killer, tall and muscular beyond even his normal Space Marine physique, and reborn as Zhufor.
Zymran was a Chaos Lord of the Word Bearers Traitor Legion who led a warband comprised of both Chaos Space Marines and daemons. He attempted to claim a pre-Heresy relic known as the Concordant Chaosium but was opposed by an Ultramarines strike force -- ancient and bitter rivals since the Horus Heresy.
At present, a Sorcerer Lord is a Chaos Lord who possesses psychic powers and is more often than not a devotee of Tzeentch, the Changer of Ways and Chaos God of Sorcery.
In the 3rd Edition of Warhammer 40,000, there was a different structure for Chaos Space Marine commanders. They could be psykers or mundanes, and the rank of "Chaos Lieutenant" existed as the second-in-command of a Chaos Space Marine force.
Since the release of Warhammer 40,000 4th Edition, however, Chaos Sorcerers have been moved to a role more resembling that of the Loyalist Space Marines' Librarians within a Heretic Astartes warband rather than possessing variable psychic abilities.
