Adeptus Custodes



"These men are my bodyguards, their lives forfeit to the guarantee of my physical safety. Of their loyalty to me there shall be no question nor doubt. I, and I alone, shall have the authority to stand in judgement over them. No other commander shall they have in battle nor in service. None shall bar them from me and none shall hamper or stall their mission. So it is decreed!"

- Ancient declaration made by the Emperor of Mankind during the Age of Strife

The Adeptus Custodes, known as the Legio Custodes before the Horus Heresy, is the Imperial Adepta responsible for guarding the Imperial Palace and the physical body of the Emperor of Mankind. It is an elite cadre of genetically-engineered transhuman warriors who are even more potent in combat than the Adeptus Astartes. They are to the Space Marines as the Emperor is to His Primarchs, and it is rumoured that they were created using the Master of Mankind's own genecode. Where Space Marines represent the mass-produced genetic soldiers of the Imperium, the Adeptus Custodes are a force of individual warriors, each a bastion in his own right.

These warriors have stood in the presence of the immortal Emperor of Mankind since before the time of the Unification Wars. For ten thousand years and more, the Custodians have stood watch over their lord and master, serving as the Emperor's personal guardians and praetorian bodyguard. During the Great Crusade these resplendent warriors guarded the Emperor wherever He went and swore to give their lives to protect His. After His incarceration in the Golden Throne following the Horus Heresy ten standard millennia ago, they have taken a far more limited role in the Imperium of Man. They almost never leave Terra and only very rarely leave the Imperial Palace as they watch over their recumbent master and patrol the precincts of the Emperor's Palace, ever vigilant of threats. It is only the Adeptus Custodes who decide who may enter the Sanctum Imperialis of the Emperor at the heart of the Inner Palace, and when they may do so.

Brotherhood of Demigods
"Give thanks to those most courageous and loyal of guardians, the Adeptus Custodes, who stand in constant vigil over the Emperor's palace. A veritable legion of warriors ready to lay down their lives without doubt for the beloved ward of Mankind. None pass through the Imperial Palace without their knowledge; steeped are they in the arcane secrets of that labyrinthine edifice. Ten thousand blades await the call to arms; to defend against any threat, from without or within."

- Atr. Unknown

The Adeptus Custodes. It is a name spoken in reverent whispers, for these warriors have stood in the presence of the immortal Emperor of Mankind, and are charged with his protection. His greatness runs in their veins, undiluted by the passage of aeons. They have been called the Emperor's right hand, for they act with his authority and fight in his name. Only now, as the threat of Chaos grows ever greater and takes its dreaded toll, does that gilded hand reach out and become an eagle's claw. The Custodian Guard are the talons of the Emperor unsheathed, and they will tear the corruption of Chaos from the Imperium no matter the cost.

Near immortal are the Adeptus Custodes, for the golden elixir of the Emperor's own blood runs in their veins. Though outwardly resplendent, there is a scar upon the soul of the Custodian Guard, an inescapable disgrace that has tainted their history and lives in the heart of every warrior, from fresh inductees to veterans over a thousand years old. Clad in baroque, golden artificer armour and armed with priceless relic weaponry, the Adeptus Custodes make for a magnificent sight. They tower over mortal men; each has the statuesque physique of an ancient hero, close to nine feet in height even without his scarlet-crested helm. Yet for all their might, for all their bravery, the Custodians were unable to prevent the Emperor from falling to his traitorous son, the Primarch Horus.

For millennia, the Adeptus Custodes have formed the unyielding core of the Emperor’s multi-layered defences. Those Custodian Guard charged with the physical protection of the Master of Mankind spend every waking second devoted to their task, refining their warrior skills and constantly testing and updating their own strategies to ensure the sanctity of the Emperor's throne. They are his last line of defence against a hostile galaxy hell-bent on Humanity's destruction. If they fail in their task, the Imperium will collapse from the inside out. Their duty is so sacred, their reputation so profound, that even Space Marines and Inquisitors kneel before them.



Though few truly realise it, Humanity teeters upon the precipice. Aliens and fiends hurl themselves against the Imperium's borders even as the rot of treachery and the mutating curse of Chaos gnaw at it from within. Under such impossible duress, Mankind cannot endure. Once, the most part of the Adeptus Custodes would have stood stoically by as the Emperor's foes advanced upon Terra, each lordly champion stern and immobile until the foe crossed the pitch-black moat of the Sol System and hammered upon the palace walls themselves. After all, to keep vigil is the oath they swore to fulfil, and they have never abandoned it, even as thousands of worlds have burned.

Now that sovereign duty has changed. In Mankind's darkest hour, a legend has emerged from the annals of history -- the Ultramarines Primarch Roboute Guilliman, an icon of authority. The coming of this legendary High Lord has galvanised the Adeptus Custodes, and after long consultation, seen them reorganised and given new life. The golden brotherhood now numbers not only guardians, but also crusaders. Alongside the anti-psykers known as the Sisters of Silence, the Adeptus Custodes bring war anew to the enemies of the Imperium. All shall learn to fear their golden warships, for they herald swift and unmerciful slaughter. These are heroes of fire and blade, and they will not stop until every threat to their immortal master lies slain.

The Firstborn
"Only in Death does Duty End."

- First Maxim of the Legio Custodes

The origins of the Custodian Guard are shrouded in myth and legend. The ancient Legio Custodes were the bodyguards and sworn protectors of the Emperor and His chosen emissaries, and when the need arose, His most deadly executioners. Genetically engineered warriors of unswerving loyalty and unshakable purpose, their might and skill-at-arms was greater even than the Space Marines of the Legiones Astartes, while their weapons and wargear were uniquely potent, representing the apex of the Imperium's technology. Their history is a long one, and for centuries they have walked in the Emperor's shadow as His praetorians and the protector of His secrets.

The Legio Custodes are by many accounts the Emperor's true firstborn, prefiguring even the Thunder Warriors. They are His first genetically-engineered, psycho-indoctrinated warriors, perfected weapons crafted by the Emperor's genius from the dread lore of the Dark Age of Technology. They are in almost every measurable way superhuman: stronger, faster, more acute of senses and more resilient even than the doomed Thunder Warriors or the Space Marines who would follow them, and so far beyond the limits of an unaugmented human as to be almost godlike in comparison. Indeed, only the Primarchs and above them the Emperor Himself exceeds them in corporeal might, and to meet them in open conflict is to court death for human or alien alike.

They are rare creatures, these firstborn of the Emperor's gene-craft. Such was their psycho-physical design, and the intricacy and sophistication of the gene-craft involved, that the modifications which went into their creation required such strict biological and psychological criteria that only a mere one in many thousands of potential candidates might prove suitable for the simplest of the steps involved in the Legio Custodes creation process. Even of this small pool of candidates, survival through the decades of alchemical augmentation and psycho-memetic training were far from guaranteed. In this fact can be seen a pattern also replicated in the Space Marine Legions, only to a far more highly pronounced degree, so that while the numbers of the Legiones Astartes were prevented from growing beyond perhaps a million at their greatest strength by the limitations inherent in the means of their creation -- a paltry sum compared to the billions of others who took part in the Great Crusade -- the Legio Custodes could never, upon the available evidence, have operated on the scale of the Space Marine Legions, even if the attempt had been made for them to do so. The number of active Legio Custodes warriors has never, it is believed, exceeded 10,000. This figure was first attained towards the middle stages of the Great Crusade and maintained diligently enough that the "Ten Thousand" itself became a cognomen for the Custodian Guard in the works of the Remembrancers and the notaries of the Imperial Court since, whatever its literal accuracy.

Certainly no more than a thousand have ever been seen together at any one time, and then only once at the famous Battle of Gyros-Thravian, fought during the Great Crusade against the Ork Warlord Gharkhul Blackfang and his vast Greenskin horde. The Primarchs Horus, Rogal Dorn and Mortarion and their Legions were vastly outnumbered and close to defeat when the Emperor led an assault from His golden Battle Barge, the Bucephelus. At the head of a thousand Custodians, the Emperor struck at the very heart of the Ork horde, confronting Gharkhul atop a towering Gargant. As the Emperor decapitated the giant, black-skinned Ork, the Custodians laid waste to the warlord's prime warriors. It is said that within moments over a hundred thousand Greenskins died and the WAAAGH! was broken. Legend has it that only three Custodians fell at the battle, their names enshrined forever and engraved on the Emperor's armour thereafter.

Wrought by the Emperor's Hand
It is not an uncommon belief, even among the learned across the wide sweep of the Imperium, to suppose the Custodian Guard are themselves some variant of the Legiones Astartes -- if so crude a term might be applied, an "advanced" form, perhaps even a second, improved iteration. While this explanation might seem to fit the facts, particularly to those without intimate knowledge of the Imperium's birth pains during the final acts of the Unification Wars on Ancient Terra, it could not in fact be further from the truth.

The bloody chronicles of the Unification Wars, particularly in their earliest stages when the Emperor first rose from the nightmarish bloodshed of Ancient Terra's long night to cast down the reign of the warlords and monsters that had long carved the birth world of Mankind into a thousand slaughter-haunted pieces, are difficult now to comprehend. Many are rightly sealed from the Imperium's scholars and even the Terran Court, the dangerous truths within suppressed. But in those dark chronicles the Custodian Guard, in some form or shape, have their part as far back as any can record or those few souls who survive yet from those times can remember. Upon the pillars of the Black Manse of Nas'sau, capital of one of the earliest of the techno-barbarian holds to submit before He who was to be known as the Emperor, inscriptions record the "Lord of Lightning" coming before their warlord-kind flanked by His "four giants of crimson and gold," demanding surrender. Solar decades later, according to detailed extant records preserved in the Trans-Nordyc Akashic archives, a companion guard of thirty "Custodians", bearing Power Spears, clad in Augment-Armour and personally commanded by the Emperor, fought at the head of the newborn Thunder Legion in the assault against the formidable Maulland Sen Confederacy. One of their number is even recorded as being responsible for striking the head of the Confederation's Tyrant-Prophet from its shoulders in the aftermath of the campaign's climactic "Battle of the Red Frost".

Decades later still from this infamous battle, it would be the Custodian Guard in their hundreds, in a form akin to their most modern aspect, who would be charged with leading the cull of those same Thunder Warriors who had once served the Emperor and who had then rebelled in the wake of their forcible disbandment and internment. Only this time the Custodian Guard would be accompanied by the new gene-crafted warriors meant to replace the Thunder Warriors; the first few thousand prototype Space Marines, most of whom would go on to form the nascent I Legiones Astartes, later known as the Dark Angels. The evidence then is clear; since before the first worlds were conquered as the Great Crusade left the Sol System, since before the taking of Luna and the Treaty of Olympus, since before the Cataclysm of Ursh and the fall of the Yndonisic Bloc, before the Space Marines and before the Thunder Warriors, the Custodian Guard have walked at the Emperor's side.

Incarnate Purpose
To accomplish the ends to which the Legio Custodes were designed, not only is a Custodian's superhuman physical power honed to a razor's edge, but so also is the individual Custodian's intellect, mental fortitude and martial skill developed with ruthless application and zeal. The result is the creation not simply of a preternaturally deadly fighter or master assassin -- though they can readily serve as both -- but to create a being whose perception and apprehension of threat and how to counter it is literally beyond the natural limits of man or the powers of a machine. By means unknown and unknowable beyond the Emperor's own forbidden laboratories are the minds of the Legio Custodes programmed and fortified, filled with an encyclopaedic knowledge of all the arts of death, deceit and destruction they might encounter in their duty, and how both to counter and employ them. Beyond even this their education is prodigious, for not simply the Emperor's protectors in intention, they are also made to be His companions and with Him they are armed to converse on such matters of warfare, politics and philosophy as He wished. Most importantly, their psyches are also crafted and shaped as a master gemsmith might cut and polish a perfect stone, fashioned to precise order and pattern, a pattern to which loyalty and discipline, duty and unflinching obedience to the Emperor goes deeper than blood and bone, deeper than conscious thought or unconscious desire. If at any stage in the process the merest flaw is encountered, as with the gemsmith's search of the perfect stone, the flawed subject is discarded.

The product of these amassed arts, arcane, academic and militant, is a body of warriors these living weapons make up -- the Legio Custodes itself, the Ten Thousand. As an organisation, it is in many ways both alike and unalike to the Space Marine Legions in formation and structure, a paramilitary force unique in history, inviolate in action and answerable only to the Emperor. While each Legion was, at least at conception, a highly stratified and self-contained military organisation designed to be the shock troops and principal agency of the Great Crusade, the Legio Custodes was similarly self-sufficient and self-contained, but was never armed or expected to prosecute war, but instead to utterly dominate whichever particular close battle in which they fight. Their base of operations is Terra itself and their own domains interwoven with that of the Emperor. They hold few voidships of their own, but could command by edict any such vessel of the Imperialis Armada or later Imperial Navy to their task, and in fact requisition anyone or anything within the Imperium in extremis to serve their most sacred and undaunted task; the protection of the Emperor and His works from all the foes of humanity.

Whether serving as part of a detachment acting as the destroyers of some ill-fated foe, or tasked as a bodyguard for the Emperor or some element of His household, or even where a handful of Custodians might be deployed to act as the personal protectors to an Imperial emissary or Lord Militant, they are tireless, vigilant and remorseless. They are armed, created and trained to be the match and the death of anything they might encounter face-to-face, be that human, xenos or machine, in any circumstance of single combat, counterattack to ambush or close-range assault. Again and again has history seen the Custodian Guard stand off and defeat odds that seem beyond reason or belief. It has seen them slay monsters foul enough to have been dredged up from pure nightmare, and defeat and slay assassins born of arts both dark and subtle beyond human ken. Tested again and again, be it on alien worlds before now untrodden by humanity, or within the tangled under-hives of the domains of Mankind lost to the Age of Strife, or the twisted palaces of alien warlords, the Legio Custodes proved themselves warriors of terrifying ability. Their service and their mystery has seen the Legio Custodes quickly become a legend equal in wonder and terror even to those alongside whom they served and in the echoes of whispered stories in every corner of the burgeoning Imperium. To the common soldier and Planetary Governor alike, the golden-armoured image of the Custodian Guard is a visible sign not only of the Emperor's direct protection and the embodiment of His will and agency, but also the omen of His unstoppable wrath, as personal and as terrifying in their way as the Angels of Death, his Space Marines, are impersonal and all-conquering avatars in the minds of many of the Great Crusade itself.

The Horus Heresy
After the breaking of the Orks upon Ullanor, the Emperor returned to Terra, taking his Custodian Guard with him. The seeds of doubt he left behind soon became the roots of treachery, for there is darkness in every soul, and the Ruinous Powers have always known how to exploit it. Before a single generation had passed, the insidious taint of Chaos had infected a full half of the Emperor's Primarchs, Horus foremost amongst them. These arch-traitors spread the moral decay to the Legiones Astartes they led, and the galaxy was lit with the fires of strife and civil war.



At the climax of the Horus Heresy, the Custodian Guard fought monstrosities without number, for those in the Traitor Legions powerful enough to reach the gates of the Emperor's Palace were twisted body and soul by the baleful gifts of Chaos. A thousand victories were won by the Custodian Guard, but they all turned to ash when the Master of Mankind teleported aboard Horus' flagship, the Vengeful Spirit. There, a strike force of Legio Custodes fought the fiercest of traitors to protect their master. They were found wanting. Though Horus was defeated in single combat at the last, it was at an unimaginable cost; the Warmaster cast down the Angel Sanguinius, and dealt his gene-father a mortal blow before being slain in turn. Though the Emperor's psyche remained active within his shattered body, since that day, the Custodian Guard have stood vigil over little more than a broken corpse, wizened and immobile upon a slowly failing life support system.

Reformation
Long have the Custodians worn the shroud of shame after that fateful day. In grave ceremony they donned black cloaks to symbolise the pall of darkness that had fallen over their order. The Emperor’s realm, wracked by the tempest of heresy, was reforged by those Primarchs that survived the great upheaval. Largely through the efforts of Guilliman, the Imperium's byzantine organisations were reordered in such a way as to ensure that no one faction or power could again threaten Terra. In doing so, they relinquished some of their strength. The Legiones Astartes were divided into Chapters of a thousand. The Legio Custodes, though it kept its numerical strength of ten times that number, was reforged as the Adeptus Custodes before the time of the Second Founding, becoming castellans of the Imperial Palace whose sole and solemn duty was to protect the Emperor from final death.

To the 41st Millennium
"Ours is the duty absolute. Ours is the vigil that must never end. Ours is the timeless honour, the willing sacrifice, the penitence enduring. We stand a watch that will never be relieved, and we stand it gladly out of adoration for he who gave us life, and whose life we must, in turn, preserve. We will never earn absolution, for we do not deserve it, but those who believe that would give us pause are fools."

- Shield-Captain Tybalus Maxin

Even in the days before the Heresy, it was a rare and blessed thing to see a member of the Legio Custodes, and due to the confinement of the Emperor to the Golden Throne, it has become an almost unthinkable event for a present-day citizen of the Imperium. Even during the Battle of Terra, only a handful of Custodes joined the Emperor when He made His assault upon Horus' flagship, the Battle Barge Vengeful Spirit. Since the death of Horus and the mortal wounds he inflicted upon the Emperor, the Legio Custodes, renamed the Adeptus Custodes after the Reformation of the Imperium conducted by the Ultramarines Primarch Roboute Guilliman in the early 31st Millennium, have taken a more limited role by acting solely as the protectors of the physical form of the Emperor on Terra and the primary providers of security for the Imperial Palace. The Adeptus Custodes are the Auric Mortalis ("The Golden Death"), the dread guardians and only living beings permitted to be in the presence of the Emperor unencumbered. Now ensconced deep within the Sanctum Imperialis on Terra, they continue their eternal watch over the recumbent form of the Emperor.

Despite their long vigil, the Adeptus Custodes have continued to play an important role during some of the most tumultuous times in Imperial history. The Custodians were instrumental in ending the rule of the High Lord Goge Vandire during the Age of Apostasy in the 36th Millennium. It was the actions of a few members of the Adeptus Custodes, utilising secret passages within the Imperial Palace known only to themselves, that brought the Sisters of Battle, then known as the Brides of the Emperor, to fully realise the acts of base treason perpetrated by Vandire. After their leader, Alicia Dominica, was brought before the Emperor Himself by the Custodes through the secret passages of the Palace, she returned and executed Vandire personally for his apostasy and betrayal of the Master of Mankind.

No one knows for sure how many hidden coups, secret rebellions and misguided attempts at assassination the Adeptus Custodes have foiled. That their martial skills remain so sharp after ten thousand standard years, however, is evidence that they have not stood an idle vigil. They have been called the Emperor's right hand, for they act with His authority and fight in His name. Only now, as the threat of Chaos grows ever greater and takes its dreaded toll, does that gilded hand reach out and become an eagle's claw. The Custodian Guard are the talons of the Emperor unsheathed, and they will tear the corruption of Chaos from the Imperium no matter the cost.

In the late 41st Millennium, the personal sanction of the resurrected Primarch of the Ultramarines sent shock waves through the Adeptus Custodes. After ten thousand years of mourning, the Custodian Guard have cast off their black cloaks and taken to the sea of stars once more. The fires of battle will absolve them, a baptism of blood that washes away the stain of their one great failure. Now, they crusade once more against the dying of the Emperor’s light, a vengeance long-awaited finally within reach of their blades.

Into a New Age of Darkness
"The Emperor's realm is a festering ruin of overcrowded worlds drowning in their own ignorance and fear. It is a tumbledown ghetto that burns from end to end with the flames of war. They do not deserve their Emperor. They do not deserve us. None of that alters the fact that our duty must be done..."

- Telchor, Custodian Guard

The hour of action is nigh. With the surge of Chaos activity across the galaxy in the wake of the Great Rift's birth and the threat of eternal damnation more real than ever, the Adeptus Custodes have taken their vow of protection to its logical extreme -- they will see the destruction of those forces who pose a threat to the sanctity of Terra. First amongst these are the dread hordes of Chaos.

The best form of defence is attack. It is a maxim that has survived through the millennia, and with good reason. Of late, it has become the mantra of all Adeptus Custodes commanders. In conjunction with the alpha-level Astropaths and doomscryers that dwell within the Imperial Palace, these officers launch terrifyingly effective strikes at those whom they deem a threat to the Emperor's works. More than one galactic tyrant, laying plans for a crusade that he envisages culminating on Terra itself, has found the warriors of the Emperor descending from the heavens to strike him down before he has even taken to his ships.

There are those who believe that the Adeptus Custodes stand immobilised by ritual and rote, but they are sorely mistaken. Only the Custodian Guard know what occurs behind the Sanctum Imperialis ' colossal doors, and the lengths to which they have gone to keep their vigil. Their sacred task has by no means led to inactivity. Hundreds of wars have been fought by the Adeptus Custodes over the aeons -- some in Terra's defence, some in secret, and some further afield. Even when the din of war recedes, these warriors work to test and refine the protective aegis they hold before their master, sending agents into the Sol System to divine likely routes of infiltration and assassination so they can stay ahead of even the most inventive enemies. The Adeptus Custodes have long honed strategies and tactics in case they should be called upon to join the front line fight for Humanity's survival. The day of that remit has finally arrived. Primarch Guilliman has met alone with his father, the Master of Mankind, and emerged with a clear vision of Humanity united in battle.

Those Custodian Guard known as the Companions -- the three hundred warriors charged with the direct defence of the Emperor -- remain by his side, just as the colossal edifice of his palace continues to be bolstered by a standing army of golden heroes. The rest have taken to the stars. They have done so in no small force, for this majestic legion still numbers ten thousand blades and more. With the Sanctum Imperialis secure under the vigil of the Companions, the crusaders are free to pursue the war of aggression they have long desired, putting into place war strategies perfected over the centuries through fractal thought exercises, cogitator-spawned algorithms, long study and even simulated conflicts waged in hallucinariums. These give the Custodians a tactical edge that allows them to counter the enemy's actions before they have begun.

Rise of the Primarch
In the last days before the gathering storm broke and the Great Rift tore the void in two, a bright light of hope was kindled within the galactic empire of Ultramar. Through great sacrifice and unnatural artifice, Roboute Guilliman, Primarch of the Ultramarines, was restored from the brink of death. His coming would herald great changes for the Imperium. When the Traitor Legions fell upon the Imperial Palace at the culmination of the Horus Heresy, Roboute Guilliman and his Ultramarines were too far away to fight in their father's defence. Perhaps, had it been otherwise, the fate of the galaxy would have been very different.

Whatever the case, following his revival Guilliman was determined that he would not make the same mistake twice. Seeing the darkness rising to swamp the Imperium, he launched a desperate crusade across the stars that brought him by strange and bloody roads to the throneworld itself. Guilliman was welcomed with all honour on Terra, permitted audience with the Emperor by Aquila Commander Kalim Varanor and reinstated as Lord Commander of the Imperium by an assemblage of the High Lords of Terra. Though the returned Primarch remained outwardly stern and regal, he had been shaken to the core by what had become of his father's empire. He quickly began instating changes that would permit the Imperium to fight back against the onrushing hordes of Chaos, bulldozing the bureaucratic stubbornness and hidebound pedantry of the Adeptus Terra as he went.

The Second Battle of Terra
Guilliman's return came not a moment too soon, for he had not been long at his labours when the cascading fury of the Great Rift washed over the Sol System. Though not directly struck by Warp Storms, Terra bore the brunt of empyric shock waves that temporarily extinguished the light of the Astronomican, and wrought havoc and misery from the planet's highest spires to its deepest crypts. The Adeptus Custodes found themselves putting down riots, doomsday cult uprisings and rampaging packs of luckless petitioners driven to madness and cannibalism. Bands of Custodian Wardens stood their ground in the shadowed undervaults far beneath the palace as runic sigils burned out and timeless horrors burst from their containment cells.

Worse was to follow. Seeking to strike the decapitating blow that would bring the Imperium to ruin, a vast horde of Khornate daemons tore through the skin of reality and assaulted the Lion's Gate, initiating what became known as the Second Battle of Terra. Legions of howling daemons surged towards the Emperor's palace in a crimson tidal wave, and a frenzied battle ensued. The battleship-sized gun emplacements flanking the Lion’s Gate blasted glowing craters in the diabolical horde, but alone they had no hope of prevailing. Led by Roboute Guilliman and Captain-General Valoris, a combined host of the Adeptus Custodes, Ultramarines and Sisters of Silence marched out to meet the daemons before the walls of the Emperor's palace.

In scenes that echoed the horror of the Siege of Terra ten millennia before, the golden warriors of the Adeptus Custodes faced the Blood God's savage butchers blade to blade. This time, led by some of the Imperium's greatest champions and driven by a furious determination never to fail again, they prevailed. One by one, the eight Bloodthirsters that led the attack were blown apart or cut down. The cost in lives was great, with noble defenders who had stood guard over the Emperor for thousands of Terran years brought low by the brazen weapons of Khorne's hateful daemons. Yet even as the skies boiled blood-red and carmine rains slicked the ground, the legions of Khorne faded from reality with howls of frustration and rage.

Marshaling for War
The Lion's Gate Incursion proved a stark truth. While great swathes of witnesses were corralled and exterminated by the Inquisition, and efforts made to obliterate all evidence of the conflict, the masters of the Adeptus Custodes formally recognised that Terra's defence could no longer be guaranteed without greater proactive measures. If the servants of the Dark Gods had bypassed the defences of the cradle of Humanity. Behind locked doors, complex wards and layers of psy-protections, Valoris and Guilliman ratified a formal amendment to the role of the Adeptus Custodes. The palace must still be guarded, of course, and the Companions' watch must continue within the Emperor's throne room. However, as a logical extension of the vows of duty they had sworn, the Adeptus Custodes committed to greatly extending their extra-solar activities.

Aided by oracular doomscryers and alpha-level astropathic intercepts, and guided in part by the continued efforts of the Eyes of the Emperor, more shield hosts than ever before struck out from Terra. The aim of these forces was to exterminate utterly the most deadly threats to the Emperor Himself. This mission might take them all across the galaxy, even into the shadows of the Imperium Nihilus beyond the sprawl of the Great Rift, but always their focus would be the sanctity of Terra. In this capacity a number of shield companies attached themselves to Guilliman's Indomitus Crusade, reprising the role of the Emperor's emissaries in bearing Primaris reinforcements and technology to the beleaguered Space Marine Chapters, and ensuring they understood that this was a gift from the Master of Mankind himself. It was not to be squandered or refused.

Other shield companies relocated to permanently garrison the Sol System's outer defences, or travelled further afield in order to watch over the primary warp routes that remained stable paths to the throneworld. Others still took even more esoteric mantles, becoming hunters after arch-heretics, questors for artefacts crucial to the ongoing survival of the Imperium, or redoubling their efforts in their wars against Humanity's hidden foes. Not since the Great Crusade had so many Custodians bestrode the stars.

The Indomitus Crusade
"The hotter the forge, the finer the blade, or so they say. The forge of war in which we now find ourselves blazes hotter than anything the Imperium has seen in ten millennia. We of the Adeptus Custodes were built to endure these fires. They will not be our end. Instead, we will be honed to the finest cutting edge, that we may be the bane of even the foulest heretics."

- Captain-General Trajann Valoris

The Adeptus Custodes, for long millennia the bodyguard of the Emperor, were charged with the unthinkable -- to leave His side and strike against those who would see the Master of Mankind dead. Just as a spring tightly wound uncoils with all the more force, the Adeptus Custodes have taken war to the enemies of the Imperium with extreme alacrity and vigour. It is tradition that when one of their number falls, Terra mourns, and the giant Bell of Lost Souls is rung in memoriam; with a new era of war upon them, that sonorous toll has been heard more frequently than ever. They do not fall easily, however, for they have access to the finest weaponry, and the museum-arsenals of the Imperial Palace are theirs to use as they see fit. Few post-Heresy variations of tank, aircraft or weapons systems are at their disposal, but they are perhaps stronger for it – every weapon the Custodian Guard uses to wage war has earned its place a hundred times over. Their armoured support elements were perfected when the Imperium was still in its infancy, and they remain just as potent, their machine spirits more bellicose and powerful than any latter-day equivalent. The Adeptus Custodes employs squadrons of gold-hulled gunships -- some of these are the very same craft used during the Horus Heresy, painstakingly maintained and blessed each day with sacred oils and unguents.

When a direct vector of invasion is called for, the Adeptus Custodes utilise Godstrike pattern teleportarium arrays, appearing in the midst of the fray in storms of golden light. Their spaceships have ancient translocation bays where blessed incense drifts in the chill air, each station permanently attended to by high-ranking Tech-Priests and blessed to such a degree that even Contemptor Dreadnoughts can be teleported straight into battle. The warriors inside, their armour proof against the wrenching forces of this arcane technology, shake off their disorientation in a heartbeat before launching thunderous assaults their foes could not have seen coming.

The willpower and fortitude of the Adeptus Custodes is such that even the most fiendish sorcerers find their mental assaults rebounding from a wall of sheer conviction. The Custodians share the blood of the Emperor, after all, and their loyalty to their primogenitor is unshakeable. If the Adeptus Custodes could be said to have a weakness, it is that they fight as individuals rather than squads of soldiers, as proud lions rather than cunning wolves. Each wears armour crafted to his particular physique, fights in whatever style he deems most effective, and is given free rein to attack or defend as he sees fit. This makes him a terrifyingly effective combatant -- a single Custodian can break a charging horde by himself, though he may take a few good hits in the process. To outsiders, their supreme self-confidence may seem like arrogance. They pay little heed to mortal men, and even the Adeptus Astartes are kept at spear’s length for their former transgressions. Yet the reason is a noble one. Every act, thought and deed is made for the furtherance of the Emperor's cause, and therefore the survival of the Human race. Those who stand in the way of such paragons of surety do not last long.

Exemplars of Terra's Might
There are many ranks within the Adeptus Custodes, the highest of which is that of the Captain-General. Following in the footsteps of historical titans such as Constantin Valdor, this lordly warrior is entrusted with an autonomy that eclipses that of even a Chapter Master. Occasionally chosen to serve as one of the High Lords of Terra, the Captain-General has ruled over the Legio Custodes since the order's inception, and is tasked with the solemn duty of safeguarding the Golden Throne and directing the gleaming warriors that guard it. Under his auspices are Supreme Castellans, Aquila Commanders, Shield-Captains and a dozen ranks besides.

The Custodian Guard have always fought as champions rather than soldiers. They see unthinking loyalty, such as that of a dynasty or a conventional military structure, as a weakness ripe to be exploited – after all, it was such a culture that saw the Legiones Astartes turned against their creator. Only those who win the respect of the Adeptus Custodes can hope to command them, but should such a leader unite them, their loyalty will never fade.

Organisation and Structure
From outside, the organisation of the Ten Thousand seems byzantine. When they deign to account themselves at all to other Imperial bodies their ranks appear complex and highly stratified. Yet much of this is tradition, or else purposeful misdirection; in practice, the Adeptus Custodes use a robust and easily adaptable system to organise their forces.

The full details of the organisational structure, disposition and regulation of the Adeptus Custodes are shrouded in secrecy as befits an institution dedicated to ultimate security. Those outside its ranks, even though they operate close to the Senatorum Imperialis and the highest levels of the Divisio Militaris, cannot hope to know more than a degree of detail which is purely observational, and likely barely scratches the surface of the no doubt byzantine Custodes. What can be outwardly observed is contained here within this account, as are the various details and titles with which the Custodian Guard openly interacts with the other organs of the Imperium's power.

The first mystery that outsiders must cope with is that of identity. The Custodian Guard are themselves effectively ageless and as unchanging as granite, and just as impenetrable to outsiders. They each profess to a given name, often a compound drawn from the lore of Ancient Terra's roll of kings and tyrants, gods and legends. Whether or not this represents some humour or deliberate irony on the Emperor's part given the Custodian's role is something that it is perhaps unwise to speculate on. Such true names they knew as part of their birth and origin are likely obliterated by the process of their creation, but the myths that have grown up around the Adeptus Custodes have long held that each Custodian Guard garners over his centuries a long list of additional names and titles grated purely by the Emperor for their deeds, history and character. Such names are held as a secret of their Order and never betrayed to others, though some myths would have it that this roll of honour is graven in hidden fashion upon their golden armour or even etched microscopically into their very bones. It was said that Captain-General Constantin Valdor obtained 932 names prior to the assault of Horus upon Terra.

In terms of structural organisation, it is apparent that the Adeptus Custodes is unique unto itself in terms of form, offering little in common with the rest of the Imperium's agency of warfare such as the Astra Militarum of the Adeptus Astartes. This is only fitting as the Adeptus Custodes, like other elements of the so-called "Talons of the Emperor," can be more accurately described as a paramilitary rather than a strategic force, neither geared nor equipped towards the fighting or winning of wars, but to its duties of protection and where needs be, execution. The Adeptus Custodes operate as a military force, a gathering of champions each of whom possesses unassailable authority over virtually any other organisation in the Imperium. Conversely, no Imperial agent can give a Custodian orders. Even such worthies as the High Lords of Terra and Lord Commander Guilliman are able only to request – not demand – their aid.

Command Structure
As befits such a body of elite warriors, the internal hierarchy of the Adeptus Custodes is remarkably flat. The overall command of the Adeptus Custodes of course lies within the purview of the Emperor directly, but serving as the head of the Order is a single officer; the Captain-General, and due to the importance of the Adeptus Custodes in the governing of the Imperium, since they always stand the closest to the Emperor, the Captain-General often holds a position amongst the ruling High Lords of Terra on the Senatorum Imperialis. The Captain-General commands the Ten Thousand, inheriting a post that has been passed down from one gallant leader to the next ever since the mysterious disappearance of Constantin Valdor. The Captain-General has absolute authority over the Custodes, acting as the ritual proxy for the Emperor Himself and speaking with the voice of the Master of Mankind.

Below the absolute authority of the Captain-General lies the Custodian Tribunate; a senior cadre of ten veteran Custodians, forming the Adeptus Custodes' council of war and policy and who act as advisors to the Captain-General. This body has the incomparable privilege of providing their services as counsel to the Emperor Himself should He so desire it, and in the matters of the security of the Imperial Palace's inner sanctums and the person of the Emperor, no higher authority exists. Membership of this body changes periodically to ensure a blend of established wisdom and fresh ideas. A Custodian must have earned at least ten names before he can serve on the Tribunate, and have led his comrades victoriously in battle on at least three occasions. Once he joins the Tribunate, a Custodian must serve for at least ten years. During this time he will not see the front lines, for he is too busy bending all of his considerable intellect to supporting - strategically and diplomatically - the Captain-General.

Below this ruling council can be found the Custodian Prefectorate and the Shield-Captains. The distinction between the two, not apparent entirely to outsiders, is one perhaps of seniority and function, with the title of Prefect accorded as a reward of veterancy and favour in service by the Emperor, while the rank of Shield-Captain indicates an active field command over a particular detachment or deployment. These two ranks fulfill the roles of inspiring leaders, gifted generals and selfless champions. Their titles vary enormously, from Supreme Castellans and Aquila Commanders to Master Guardians, often borne in accordance with the specific duties to which they have been assigned. It is Shield-Captains that take charge of the Adeptus Custodes' military engagements; one is typically afforded overall command of an operation, while several others of his rank may lend him their strength and wisdom in a supporting capacity.

Sodalities
Below these ranks, the Custodians seem to be peers as in the manner of a warrior caste or aristocracy, rather than links in the more familiar chain of command found elsewhere in the Imperium's armed forces. Their functional titles adapt to their chosen role and panoply of war in whichever command they have been included, with the following broad distinctions applied in communication with external forces on a tactical level, their titles drawn from various ancient sources. The remainder of the Custodians possess roughly equivalent status to one another, forming loose warrior bands traditionally known as sodalities. There are varying strategic roles within the organisation to which some Custodians find themselves better suited. However, whether this be the rapid jetbike troops of the Vertus Praetors, the heavy assault specialists of the Allarus Custodians, or the unwavering Wardens, they still operate within a meritocracy that sees them afforded whatever honour their comrades believe them worthy of.

Shield Companies
A singular force of the Adeptus Custodes is referred to as a shield company. The numbers within such a formation can vary considerably, hand-picked by their Shield-Captain for the task at hand and ranging from a small band to a sizeable army complete with Jetbikes, tanks and Dreadnoughts. Under normal circumstances, a shield company includes no more than one Shield-Captain and perhaps thirty to forty Custodians.

Shield Hosts
When a larger force is required, multiple shield companies gather into forces known as shield hosts. Led by conclaves of Shield-Captains and boasting tens, sometimes hundreds of Custodians, shield hosts have the martial strength to crush enemy armies and bring entire star systems to heel. The gathering of such might is a momentous undertaking - a shield host is only assembled to accomplish those tasks that no other Imperial force could be trusted with, and its warriors march to war with a singular and implacable determination to enact the Emperor's will.

The Companions
"For one hundred years I stood my watch amidst the sombre shadows of the Sanctum Imperialis. I was still as a statue, but always ready, always attuned to dangers unseen. Days, months, years passed by in a frenzied blur beyond those walls, yet within, little moved and nothing changed. For one hundred years I did naught but wait, yet had any threat appeared, I would have struck it down in a heartbeat. For one hundred years I stood my watch, and as it ends I can tell you this – patience is a weapon."

- Custodian Warden Tybaris Constor

The Companions are a three-hundred-strong force that forms the direct bodyguard of the Emperor while He sits upon the Golden Throne. They are hand-picked for their duties by the Captain-General, who chooses his candidates based upon painstaking assessments of each warrior's performance in training and battle, as well as their mental acuity, spiritual fortitude and countless other indicative factors. There can be no more important duty in all of the Imperium than to shield the Emperor Himself. As such, no consideration for rank or veteran status is given when appointing Custodians to the Companions, and those passed over in favour of younger or less experienced candidates take no offence.

The vigil of the Companions is unending, and though they are of course rotated out for brief periods of rest, it is still a purgatorial duty. Arrayed in ranks around the Golden Throne, these wardens stand for incredible lengths of time, unmoving, unspeaking, poised constantly upon the cusp of battle readiness in case the slightest threat were to present itself. It is mentally and spiritually exhausting, even for the demigods of the Adeptus Custodes, and so when the Captain-General judges that a Companion has served long enough they will be rotated out with immediate effect, replaced by a fresh inductee to their ranks. Again, this is no mark of dishonour, merely a pragmatic admission that even a Custodian cannot perform such a taxing duty indefinitely. The longest any individual has stood the Companion's Watch was Astoran Kalos, who endured for a full Terran century before at last surrendering his place amongst the silent ranks.

Those who have served amongst the Companions are more likely to lend their talents to the grim bodyguards known as the Aquilan Shields. Such Custodians have protected the lives of the greatest and most august personages in the Imperium, most notably the High Lords of Terra themselves. From the Master of the Navigators' Guild to the High Logisticar of the Adeptus Administratum, the Lord Militant of the Imperium to the shadowed Grand Master of the Officio Assassinorum, former Companions have acted as guardians for them all. To the Ten Thousand such duties are simply an extension of their vows to protect the Emperor, in this case by safeguarding those assets most important to the successful running of his Imperium. Still, it is a role that has earned the Adeptus Custodes much favour in the eyes of Terra's noble elite.

The Hykanatoi
The main strength of the Custodian Guard comprises this role at any given time. They are the bearers of the spear, the bodyguard of the Emperor and the executioners of any who would offer threat or opposition to His will. They are the image of the golden-armoured warrior that is summoned in fear and awe when the Adeptus Custodes is brought to mind. Their numbers include variations of force, wargear and panoply such as the Sentinel Guard and Custodian Guard proper, as well as the elite Hetaeron Guard -- the most skilled fighters among a force of warriors whose martial skills are already well beyond human.

The Tharanatoi
Though there are few opponents that the Hykanatoi cannot deal with, they are not a rounded military force in the sense that they are not configured to deal with exigencies such as siegecraft or attrition warfare that fall outside their purview. However, the Adeptus Custodes still maintains the ability to deploy its forces as heavy shock troops should the need arise, or indeed to counter a foe that directs overwhelming force against it in high-intensity warfare. These counterassault forces are known as the Tharanatoi, and encompass custom-modified suits of Terminator Armour optimised for use by the Custodian's superhuman frame, as well as vastly potent portable firepower such as carried by the Sagittarum Guard, whose weapons include those few dark relics known as Adrathic Weapons --disintegration beams of phenomenal destructive potential, long gathered to the Emperor's household and entrusted to no other.

The Kataphraktoi
Long before the Emperor's retreat and seclusion on Terra after the appointment of the Warmaster Horus to command His forces, the principal role of protection and defence the Custodian Guard engaged in was a mobile one. They went wherever their master did, no matter what blasted alien world or lost cityscape of ancient glory He trod. In this the elements of speed and mobility were paramount to their success, as was reconnaissance and counterstrike in lightning response to threat. Those of the Legio who specialised in such tactics and the means of employing them were called the Kataphraktoi; they flew interceptors and gunships of sublime sophistication and power, and piloted a range of repulsor-lift grav-vehicles; tanks, transports and strike skimmers, Jetbikes and interface flyers advanced beyond anything else in the Imperium's arsenal.

The Ephoroi
The division of the Custodian Guard about which the least can be said for certain, the Ephoroi were those of the Order that were tasked with covert operations, countersurveillance and the vitally important task of simulated attack and infiltration. It was they who tested the Legio Custodes defences and preparations just as foes would, as well as conducted their own hidden missions to dispose of potential threats within the Imperium, and enact final and sometimes utterly secret justice as the Emperor's will demanded it. There are those who have posited that where the Ephoroi ended and the powers that controlled the Officio Assassinorum began at certain junctures was difficult even for the wisest of the Lords of Terra to discern, and it is certain when they wished that the Assassins of the Temples of Terra were the Legio Custodes to command. It is clear from ancient Imperial records that the Custodians participation in the so-called Blood Games -- a series of war games in which Custodians seek to identify all of the possible ways that the Imperial Palace could be infiltrated or assaulted -- that Custodians were trained in the arts of assassination, both improvised and professional, in order to counter possible attempts on the life of the Emperor. It was not uncommon for several Custodians to be on detached duty for these Blood Games so that the Legio remained vigilant against developing threats to the Emperor's person. Furthermore it is clear that the Custodes were also well-versed in the political etiquette of Terra, and have been known to act outside of Imperial law, to infiltrate influential Imperial noble houses and to investigate any potential threats. This aspect of the Custodian mindset was advantageous, given that the Captain-General of the Order often shared a seat upon the Terran Court, which allowed him to navigate the political manoeuvring of the Imperium's various organisations while still remaining an awe-inspiring warrior. It is unknown if this particular branch of the Custodians still functions in the present era of the late 41st Millennium.

The Moritoi
The smallest and most singular division within the Legio Custodes was the Moritoi; the "honoured dead who walked". Just as with the Legiones Astartes, it was possible for a Custodian Guard, having suffered injuries so terrible that even they could not recover from them but within whom the vital spark of life remained, to be interred within the cybernetic life support sarcophagus of a Dreadnought. The first of these was made while the Unification Wars were being fought, in a modified Ur-Gholem Pattern Dreadnought, the first iteration of its kind intended for use within the Thunder Legions, and as the number of Dreadnought patterns and subtypes within the Imperium's arsenal increased across the Great Crusade's decades of warfare and innovation, so too did the Legio Custodes keep pace with these developments. Though they remained relatively rare, with less than perhaps a hundred Dreadnoughts of the Legio Custodes in service at the time of Magnus the Red's folly and the subsequent attack on Prospero, they represented a phenomenally powerful concentration of force, most having had their chassis upgraded to the Achillus Pattern, a variant of the Contemptor Dreadnought manufactured with materials and technologies far beyond even the vaunted war machines of the Legiones Astartes.

The Shadowkeepers - Wardens of the Dark Cells
There are terrible things locked away beneath the Emperor's palace, eldritch terrors from the depths of Old Night that could annihilate the Imperium. To the Shadowkeepers falls the duty of standing guard over them unto the end of time. The Shadowkeepers hold the keys to the rune-locked portals hidden deep beneath the Imperial Palace. They alone know the ways by which the runic locks may be disengaged, the wards unbound and the sanctic circles breached. They alone know that these things must never happen, for the Dark Cells hold such horrors at bay that Mankind's sanity would not survive their release.

A full shield host is devoted to this grim responsibility, over a hundred Custodians patrolling the dark and silent corridors, vigilantly watching over the last terrors of Old Night. It is a task that would soon drive most men mad, for though neither sight nor sound can escape the forbidden cells, the air of those corridors is charged with dread.

A perpetual menace thickens the shadows and makes them crawl. Even the superhumans of the Adeptus Custodes are forever on edge in those dark oubliettes, for the sense of unspeakable threat never wanes. It is a testament to the discipline and spiritual fortitude of the Shadowkeepers that they stand their guard unflinching, sometimes for decades at a time.

The ranks of this shield host include many Custodian Wardens, whose oaths of protection help them to focus upon the task at hand to the exclusion of all else. The leaders of these forbidding sentries carry ancient weapons of mysterious provenance, their use intended as a last resort should anything ever break free from the Dark Cells.

For ten thousand years the Shadowkeepers have performed their duty, yet the coming of the Great Rift changed everything. With the power of Chaos spilling raw and seething into the spaces between the stars, new abominations have come to light. Worse still are the cells that stand suddenly empty, the entities and artefacts once contained within spirited away by some unholy force to curse the galaxy once more. Fearing the consequences of such dread remnants of the Age of Strife falling into the wrong hands, the Shadowkeepers at last sent warriors out into the galaxy. These jailers must trammel that which should not be, slaughtering all who seek to impede them, before returning their foul prizes to the cells where they belong.

The Lockwarden
There have been many Shield-Captains charged with mastery of the Shadowkeepers. This appointment confers the title of Lockwarden, a name that is borne in perpetuity and garners solemn respect from every other member of the Ten Thousand. The Lockwarden must be the sternest of all guardians, the most unrelenting and alert gaoler on the face of Terra. Moreover, should any creature or relic escape the Dark Cells, or newly emerged threat need to be imprisoned therein, it is the duty of the Lockwarden to personally oversee the operation.

The current incumbent of this position is Shield-Captain Borsa Thursk, who has been Lockwarden for a century and a half. He is a grim and frighteningly intense warrior whose utter fearlessness and steely vigilance make him ideal for his role. It speaks volumes about the dire condition of the galaxy that Thursk left Terra but twice before the breaking of the storm, yet he has barely set foot there since the Great Rift yawned wide.

The Aquilan Shield - The Gilded Guardians
"The duty of the Emperor's defence does not end at the walls of the Imperial Palace. Our war is like an endless game of regicide, played over countless boards against infinite foes at once. In such a contest one must be constantly pre-emptive, always cunning and ever ready to seize any advantage that presents itself. Our gaze must rove far afield, and our every move must be perfectly executed. To do any less is to court final defeat."

- Captain-General Trajann Valoris

Certain servants of the Emperor bear great responsibilities deemed directly relevant to the safety of Terra. Such esteemed figures are afforded the protection of the Aquilan Shield, at least until their usefulness is thought to be at its end. As the doomscryers of the Imperial Palace sift the tides of the empyrean for warnings of disaster, they also take note of those who - through example, thought or deed - are likely to avert such catastrophes before they threaten the Golden Throne. These fated individuals are honoured with the protection of the Aquilan Shield, for in this way a small band of Custodians can ensure a significant martial or spiritual asset survives to act in the Emperor's defence.

The Aquilan Shield are an informal brotherhood laced through the ranks of the Adeptus Custodes. They typically operate in small warrior bands, journeying across the stars to stand watch over their charges wherever they may be. No warning is given nor permission asked – the warriors of the Aquilan Shield appear as if from nowhere, avatars of the Emperor's will who announce their quarry to be under the protection of the Master of Mankind. Such an honour is beyond compare, and is never refused no matter the circumstances or the individual chosen.

The Aquilan Shield have acted as bodyguards to High Lords, Sororitas Canonesses, Lord Inquisitors, Astra Militarum generals and Space Marine Captains. They have even protected two crusade leaders bearing the title of Warmaster, staunchly ignoring the historic associations with he who first held that rank. Yet they have also appeared amidst flares of golden light to watch over firebrand frontline preachers, bewildered militia leaders and others of apparently little import. The only unifying factor amongst them all is that, while attending their duties beneath the gimlet gaze of the Emperor's own guards, these individuals are expected to achieve incredible things in the defence of the throneworld.

The Aquilan Shield fight to ensure such a future comes to pass, shielding their charges from harm until the exact moment the usefulness of the person under their protection is deemed spent. At that point they depart without a word, leaving those they guarded to look to their own defence. Tragedy often follows, but this is of no concern to the Aquilan Shield - providing it does not jeopardise the safety of the Golden Throne.

The Dread Host - Instruments of the Emperor's Wrath
Fear is a familiar weapon to the Imperium, used to deter enemies and keep seething populations in line. Yet there is no terror as pure and absolute as that invoked when the Emperor's own fury is unleashed to punish his foes. The Dread Host represents a breathtaking concentration of military might. It numbers hundreds of Custodians, organised into multiple shield hosts and transported aboard a trio of pre-heresy warships known as the Moiraides. The nature of this army is simple: they are the deliverers of the Emperor's judgement, his anger and his punishment made manifest.

Not for them the pinpoint rapid strike, the hidden war or the measured defensive action. Instead, the assembled Shield-Captains of the Dread Host identify the most visible and dramatic threats to the Segmentum Solar and unleash upon them such overwhelming annihilation that it sends shock waves rolling through the warp itself. Sometimes one warship is sent, sometimes two; only a handful of times in the entire history of the Imperium have all three of the Moiraides loosed their passengers against a single foe. Yet always the effect is the same. Spearheaded by dozens of Allarus Custodians, the Dread Host fall upon their victims with unstoppable force.

They slaughter the enemy's warriors and reduce their war engines to wreckage. They cast down their false idols and set them aflame. They topple their cities, sunder their strongholds, and butcher their allies and followers. They make grisly examples of those who would dare lead such a challenge to the Emperor's dominion, ignoring all attempts at surrender and foiling all bids at flight. By the time the Dread Host are done with their war, nothing remains of their chosen victims but the gruesome tales of their brutal demise at the Emperor's hand.

The Dread Host have smashed Ork WAAAGHs!, obliterated rebellious star systems and crushed traitor crusades. They have fought against enemies thousands of times their number and humbled them through strategy, speed and strength. With every campaign they spread the terror of the Emperor's wrath. The breathtaking bloodshed and absolute destruction they leave in their wake has dissuaded hundreds of uprisings and invasions before they could even begin.

The Solar Watch - Castellans of the Blessed Worlds
The Sol System is amongst the most heavily fortified of Mankind’s stellar holdings. The Adeptus Custodes consider its worlds, star forts and space lanes to be extensions of their master's palace, and ensure they are guarded accordingly. From the vast orbital fortresses of Luna to the cloud-keeps of Jupiter and the deep-space star forts of the Halo Belt, Humanity maintains hundreds of strongholds throughout the Sol System. Billions of weapons point menacingly into the dark gulfs of space, ready to unleash spectacular devastation upon any foolish enough to threaten Mankind's seat of power. Armoured towers and gargoyle-festooned bastions loom over every approach, sanctified against the foul machinations of the Emperor's many foes. Entire fleets of Imperial Navy ships prowl the space lanes, vigilant for the slightest threat. Yet perhaps the most formidable of all Terra's outer defensive measures are the Custodians of the Solar Watch.

Consisting of several shield companies of varying strength, the Solar Watch swear binding oaths to keep guard over the outer bastions of the throneworld. They see themselves as the first true line of defence for the Imperial Palace, and believe that it is their duty to ensure that no external threat ever makes it as far as Terra. To this end, they constantly patrol routes between the worlds and void structures of the Sol System, ever vigilant for danger.

Though they typically travel via naval craft and intrastellar trade ships, the Solar Watch maintain a formidable concentration of Venerable Land Raiders, and are typically able to deploy forces that are predominately, if not entirely, mechanised. This allows them to respond swiftly, and with overwhelming force, to any potentially threatening situation that may develop. While such dangers are not common within the Sol System, they are certainly not unheard of; the Solar Watch have been instrumental in bringing an end to Daemon-worshipping cults, Inquisitorial coups and subtle xenos incursions on every world bar Mars. While their authority technically extends to the red planet, the Adeptus Custodes are wise enough to maintain cordial relations with the servants of the Omnissiah, and so travel to that world only occasionally, trusting the Cult Mechanicus to police its own deviants.

Talon Sorties
The more aggressive of the Captain-Generals have traditionally charged the Solar Watch with performing sporadic Talon Sorties. These involve the watch gathering shield-company-strength forces and launching strikes against prevailing threats in the systems closest to Terra. The Solar Watch do not waste their resources in war zones already heavily invested in by Imperial forces. Rather, they sally out to destroy developing threats or eliminate enemies that have broken existing Imperial lines. Deploying aboard their Venerable Land Raiders, they slam into their enemies in fast-moving armoured spearheads. Prioritising the slaughter of command elements and heavy combat assets, the Solar Watch cripple their enemies' capacity to function as an army of conquest before abruptly withdrawing, leaving lesser Imperial forces to mop up what remains. After all, the duty of guarding the Sol System is a vital one, and the Solar Watch cannot leave their posts for long.

Emissaries Imperatus - Heralds of the Golden Throne
"Through the artifice of the Martian priesthood were these warriors created. By the grace of the almighty Emperor are they given now to you. Silence your questions and instead rejoice at the honour done to you this day. You are handed the gift of hope by the immortal Master of Mankind Himself, and you will accept it with sincere and solemn gratitude lest you be taken for the traitors that you profess to hate."

- Sanash Gallimedan, Emissary Imperatus to the Hammers of Dorn Chapter

In the days of the Great Crusade, the Emperor often entrusted crucial messages or artefacts to be borne by his Custodians. It is a duty they still fulfil now, speaking with the authority of the Master of Mankind himself. Though the Emperor has long been confined to the Golden Throne, there are those amongst the Ten Thousand who claim to hear their master's voice during their meditations, and to feel his hand guiding them. To their comrades there is no implication of divine intervention in this, for the Custodes have never viewed the Emperor as a god. They merely see their liege's indomitable will at work, reaching out from his shattered frame to direct his praetorians as he did when he could still walk amongst them.

Those who feel the Emperor's guidance the keenest become Emissaries Imperatus. They band together in like-minded groups and, through discussion and meditation, interpret what it is that the Master of Mankind wishes them to do. With the tacit approval of the Captain-General, they bear the Emperor's words across the Imperium to commanders who must hear them, or occasionally unlock some ancient device from the palace vaults and bequeath it to whichever champion can wield it best. Their words have redirected entire crusades, and seen threats intercepted and archeotech riches won that might otherwise have passed the Emperor's servants by.

For thousands of years the Emissaries Imperatus have been seen abroad, but rarely and in small numbers. Yet with the return of Guilliman and the commencement of the Indomitus Crusade, their activity has increased considerably. When the Primarch announced his intention to bear the secrets of the Primaris Space Marines to the loyalist Chapters, there was some resistance from the Adeptus Custodes, who feared strengthening those who might one day rebel against the Emperor once again. Yet dozens of Emissaries Imperatus stepped forwards to intercede, stating this was the will of the Emperor. They accompanied Guilliman's Crusade, many of them taking to the air as Vertus Praetors, the quicker to deliver messages of reinforcement to the embattled Space Marines. The presence of the Adeptus Custodes also ensured that even the most traditional Chapters accepted the Primaris warriors into their ranks. One does not decline a gift from the Emperor's own hand, after all.

The Eyes of the Emperor
Though functionally immortal, even the warriors of the Adeptus Custodes eventually tire. Some suffer physical hurts that impact upon their ability to perform their duties, with lost limbs, artificial eyes or augmetic organs lessening their physical perfection. Others find their mental faculties beginning to erode, however slightly, acknowledging that their reaction times or mnemic awareness are not quite what they once were. For the vast majority of warriors, a tenth-of-a-second reduction in the speed at which blows are stuck or parried might be considered negligible. For a Custodian, it is error enough to necessitate that their watch come to an end.

When a Custodian judges himself no longer fit for duty he surrenders all of his equipment to the Hall of Armaments and vanishes into the void of the galaxy clad in hooded black robes. Such noble exiles still serve the Emperor, however, for wherever they travel they observe. Some work alone, dark and ominous figures slipping through the shadows of the Emperor's realm. Others cultivate networks of informants and agents, using fear and intimidation to secure compliance where loyalty and honour will not suffice.

Should they bear witness to a situation developing that they believe might threaten Terra or the Emperor, these watchers use secret channels to communicate a warning to the Captain-General. So do response forces of the Adeptus Custodes launch punitive and often pre-emptive strikes throughout the Imperium, forewarned of danger by the Eyes of the Emperor.

Ranks and Functional Formations

 * Captain-General of the Adetus Custodes - The senior-most officer within the ranks of the Adeptus Custodes, the Captain-General is the Emperor's most trusted companion and guardian, a watchman of inviolable purpose and all but unmatched fighting skill. Due to the singular importance of the Adeptus Custodes, who stand the closest to the Emperor in eternal vigil, the Captain-General holds a position amongst the ruling High Lords of Terra on the Senatorum Imperialis.
 * Shield-Captain - The rank of "Shield-Captain" is a generalisation used when referring to one of the senior ranks within the Adeptus Custodes, as the upper command of this elite paramilitary organisation is far from transparent to outsiders. Within the Adeptus Custodes such senior ranks range from Prefect to Lictor, Proconsul to Tribune, following the ancient patterns of Terra's lost history. Elevated both through the trust held among their peers for their judgement and skill, but first and foremost advanced by the direct approval and in some cases intervention of the Emperor Himself, these are warriors not only of consummate and superhuman ability, but also rare insight, acument and knowledge. Afforded the rarest of and finest of the Imperium's arms, each of these legendary fighters command the Adeptus Custodes against all manner of threats against the Emperor, His works and His domains.
 * Tribune - During the Great Crusade and Horus Heresy eras, below the absolute authority of the Captain-General was the Custodian Tribunate; a senior cadre of of perhaps ten in number, which formed the Legio Custodes' council of war and poly. This body had the incomparable privilege of providing their services as counsel to the Emperor Himself should He have so desired it, and in the matters of the security of the Imperial Palace's inner sanctums and the person of the Emperor, no higher authority existed. By the modern era, sadly, there were only two such positions that were still maintained by the Adeptus Custodes. One of these Tribunes served as the commander of small cadres of Custodians across the wider galaxy, taking the fight to the myriad enemies of Mankind, while the other served as the master of the elite Hataeron Guard -- the personal Companions of the Emperor -- who oversaw the security of the Sanctum Imperialis.
 * Prefect - The title of Prefect is accorded as a reward of veterancy and favour in service by the Emperor.
 * Custodian Warden - Custodian Wardens can be recognised by the ceremonial robes that they wear over their armour. These are a mark of their veteran status, for every Custodian Warden has seen at least five centuries in the Emperor's service. Those Wardens that do not carry the iconic guardian spears of their order wield heavy-bladed Castellan Axes, which lend themselves to an elegant and brutal combat style. The Wardens can also fire concentrated volleys of bolt fire from the hafts of their weapons, scything down those who attempt to stay out of their blades' devastating reach. The Wardens are known amongst their comrades as level-headed and endlessly patient watchmen. Upon accepting the robes that mark their station they swear binding oaths to fight as immovable sentinels, a living fortress of auramite and sinew that no foe will ever breach. Each Warden's oaths are personal, written by the Custodian himself after a full year's contemplation sat in meditation upon the precipitous ledges of the Gallowtower. To break their vows would be worse than death to these warriors, and their determination to uphold them bolsters their already formidable wills to something of truly frightening intensity.
 * Custodian Guard - When shield companies of the Adeptus Custodes strike out to do battle with the enemies of Mankind, it is the Custodian Guard that form their backbone. These warriors are rank-and-file infantry only insomuch as their numbers are greater than those of the other, more specialised Adeptus Custodes warriors. Even a single one of their number is a terrifying force of destruction, his every shot perfectly placed, his every cut, thrust and stab a masterclass in bladesmanship, footwork and combat awareness that sees enemy corpses fall like dead leaves at his feet. Ferociously strong, phenomenally resilient, utterly without fear or doubt, the Custodian Guard are the equal of many foes' most elite warriors. Their traditional armament is the guardian spear, a golden halberd so heavy it would take several men to lift it. Conversely, some Custodian Guard prefer to enter battle armed with a sentinel blade and storm shield. The sentinel blade is a broadsword of daunting size, so large its hilt is flanked with the double barrels of a bolt caster that can lay down a hail of short-range fire. It is a testament to the strength of the Custodians that they can wield these powered blades one-handed. When coupled with the armoured bulwark of the storm shield – whose protective powers are augmented with an inbuilt energy-shield generator - this potent combination allows the Custodian Guard to cut their foes apart while weathering even the most devastating of attacks.
 * Vexilus Praetors - A Vexilus Praetor is a veteran of one of the Adeptus Custodes' shield companies, who bear aloft proud standards known as Vexillas, to war. More than just standards to inspire adulation or terror, their inbuilt technologies provide invaluable battlefield support to the Custodians fighting in their shadow. Each vexilla is created on Terra, painstakingly fashioned over a period of one hundred years by the oath-sworn artisans of the Tower Aquilane. Upon their completion, these beautiful standards are borne amidst processions of craft-thralls, Ministorum Priests and heraldic servitors to the Auric Eyrie, where they are held upon stasis-podia until required. Each vexilla is a towering banner topped with the Imperial Aquila, the ultimate symbol of the Emperor's authority. The Custodes alone are permitted to display it as their foremost heraldic icon, and its inspirational effect upon those around them is nothing short of electric. Hefted high above the anarchy of the battlefield, the vexilla forms a golden beacon of truth and light that fills true servants of the Emperor with awe. Beneath the winged shadow of the Aquila, even the humblest defender of Humanity feels the touch of the Emperor upon their soul. Meanwhile, the enemies of the Imperium cower in dismay; dread clouds their minds and saps their strength at the thought that the Emperor's greatest warriors are poised to tear them apart.
 * Hataeron Guard - Part of the inner circle of the Adeptus Custodes, the Hataeron Guard serve as the Emperor's closest protectors, aides and confidants, leaving His side rarely but for the direst of circumstances. Selected individually for their service by the Master of Mankind, they represent some of the most potent fighters in the Imperium, almost like demigods of the battlefield. During the earlier years of the Great Crusade, when the Emperor still walked amongst Mankind, the Hataeron were a regular feature upon the worlds deserving of His attention. Yet as His actions were turned elsewhere, His inner guard would follow too, becoming almost a myth in their absence. In the 41st Millennium, it is said that only 300 of these elite Custodes serve as the personal guard of the Emperor, called the Emperor's Companions. They are charged with the eternal vigil over the the Emperor's Sanctum Imperialis chambers at all times and are privileged to always be in His physical presence.
 * Allarus Custodians - The Allarus Custodians deploy with sudden fury to tear the throat from the enemy army. These warriors wear suits of Allarus Terminator plate, expertly crafted armour whose worth can be measured in worlds. Allarus armour is a marvel of craftsmanship. It provides its wearer with an exceptional range of movement and near-unencumbered speed, augmented strength and resilience, and the survivability to stride unharmed from the blast of a macro-cannon shell. Coupled with the protective blessings of the Emperor, Allarus Terminator plate is arguably the most effective man-portable combat armour in the entire Imperium. Just as well, for the battles fought by Allarus Custodians demand nothing less. Their weapons, too, are formidable. They heft guardian spears twice the height of a man, or swing massive castellan axes that can bisect a Chaos Lord or lop the head from an Ork psyker with a single blow. To supplement these weapons, Allarus Custodians also wield balistus grenade launchers upon their left forearms, which are capable of launching concussion grenades that explode amidst bursts of electro-exorcist chaff and overwhelming light and sound. Hand-picked by the Captain-General from amongst the most bellicose of the Ten Thousand, Allarus Custodians relish the chance to plunge into the most lethal battles. So aggressive and heroic are these warriors that, when the situation demands, they have been known to splinter their units entirely after the initial strike and scatter through the enemy's rear lines. Fighting as lone figures, the Allarus Custodians eliminate key targets, sow anarchy and confusion through unsuspecting forces, and completely destabilise the foe's formation before fresh Adeptus Custodes forces arrive to end the conflict. It is an effective tactic that has seen more than one heretic fortress fall from within.
 * Aquilon Terminator Sodalities - These elite warriors wear Tactical Dreadnought armour, known as Aquilon armour, that was specifically developed for the ancient Legio Custodes use. Advancing yet further upon the Cataphractii Terminator armour patterns, the Aquilon pattern took into account the enhanced physique of the Custodians as being able to bear more weight and strain than even a Space Marine, and so is fitted with additional integrated power systems and capacitors which make up for some of the limitations of the origin-pattern. This enables the Aquilon pattern to retain the Cataphractii pattern's famous durability, but allows for a higher degree of speed and manoeuvrability the former lacks. Within the ranks of the Adeptus Custodes, Aquilon Terminator Sodalities are only employed rarely, and only as need dictates, particularly on those rare occasions where they are required to operation under conditions designated as 'Zone Mortalis' or required to storm a breach.
 * Sentinel Guard - Sentinel Guard Squads are the defensive formations of the Adeptus Custodes, designed to function as a mobile bulwark to protect emissaries on hazardous ground and hold defensive lines against the most grievous onslaught in open battle. In order to achieve this, they are equipped with energy field-reinforced 'Praesidium' shields -- a precursor technology to that later employed by the prototype Legio Astartes Storm Shields -- which are able to resist the heaviest weapons fire. When deployed outside the walls of the Imperial Palace, their charge is often to protect key aspects of allied detachments and resources liberated from the enemy. However, it has been witnessed during large scale sudden assaults that their close formations also served to disrupt enemy lines. While they still retain the loose unit structures of the Adeptus Custodes, the Sentinel Guard by their nature utilise a greater synchronicity between warriors in service to the various phalanx formations that could be required of the squad at any given moment.
 * Vertus Praetors - Vertus Praetors are airborne warriors whom act as the eyes and ears of their shield companies, soaring over the battlefield and voxing word of the enemy's movements. Squads of Vertus Praetors swoop into battle astride powerful Dawneagle jetbikes. Veteran warriors who have seen battle on a hundred worlds, these Custodians know the true value of speed: not simply to bring the enemy to battle, but to direct their might precisely where and when it is needed most. Wherever they see their comrades hardest pressed, there the Vertus Praetors strike like golden lightning to bolster them. Each Vertus Praetor is a master combatant who has already honed his superhuman skills amongst the ranks of the Custodian Guard. They are expert marksmen, able to place perfect kill shots even while screaming at breakneck pace through tangled ruins or dense forests. Their close-quarters prowess is no less exceptional; a Vertus Praetor can open the throat of a heavily armoured foe in a single pass. They can analyse even the most chaotic conflict in a heartbeat, reacting with incredible speed to evade obstacles and run down their foes, processing battlefield developments with breathtaking rapidity. The exceptional skill of the Vertus Praetors is augmented by their superlative wargear. As well as being protected by auramite armour, these warriors wield enormous Interceptor Lances. Taller end-to-end than an Ogryn, and perfectly weighted, these fearsome weapons boast adamantium blades wreathed in disruptor fields. Vertus Praetors are masters of hit-and-run strikes, driving their lances clean through their precisely chosen targets before ripping them clear again as they speed past.
 * Agamatus Squadron - The Agamatus squadrons specialise in the use of one of a number of customised grav-skimmer and and jetbike designs still utilised by the Adeptus Custodes -- the heavy duty, plasma motor-boosted Gyrfalcon Pattern as their steads in battle. The increased power of the design supports not only the heavily armoured Custodian Guard, but also allows it to mount a powerful Iliastus Pattern Bolt Cannon as its on-board armament. The Agamatus Squadrons exploit these war machines to operate both as a rapid response and suppression unit in the field. In this they operate much in the manner of the elite cavalry forces of ancient times, screening the main Adeptus Custodes force from potential encirclement, reacting quickly to blunt enemy attacks, and hunting down mercilessly any foe which breaks and flees before the might of the Adeptus Custodes, ensuring the utter extermination of the enemy.
 * Pallas Grav-Attack Squadron - Pallas Grav-Attack Squadrons specialise in the use of the Pallas Grav-Attack vehicle, utilising it as a highly manoeuvrable hunter-killer, and for its rapid strike capacity greater than that which could be afforded by the use of ground troops alone. They often use the superior agility of these advanced vehicles to inflict devastating hit-and-run assaults on the enemy or to hunt down fleeing targets. In addition, its abilities allows the Pallas Grav-Attack Squadrons to also be used as reconnaissance units or as skirmishing forces large enough to pin or delay the enemy in place as the main bulk of the Adeptus Custodes detachments are deployed.
 * Sagittarum Guard Sodalities - Though less common within the ranks of the Adeptus Custodes than their peers, those warriors who comprise the Sagittarum Guard Sodalities nevertheless fulfill a number of vital roles within the Custodian's order of battle. Their art of war, in contrast to the rest of the Custodian Guard, is focussed on the slaying of the foe primarily at distance and upon the devastating application of firepower on the battlefield. In addition, the Sagittarum have entered legend as the hawk-sighted sentries of the Terran walls, charged with vigilance over the external borders of the Imperial Palace in ready anticipation of attack. Through decades of duty, their ability to recall movement patterns, faces and speech even years after the original incident was honed even more so than that of their peers, and as such their enhanced ability to analyse crowds for anticipated response grew in import upon the battlefields of the Great Crusade. Their skillset was cultivated so that they could precisely exercise the greatest threats of an enemy assault, annihilating it in the actinic fire of their deadly weapons.

Custodes Creation and Training
As has been mentioned, the Custodian Guard and the Space Marines are related in form, as perhaps might be expected of works of a same creator's hand, but they are very different in function and capacity. There are of course similarities between the two. Both are physically transformed well beyond "natural" human limits in terms of strength, endurance and fortitude, and fitted for inhuman environmental adaption and resilience, though in this the Adeptus Custodes are the markedly superior of the two in might, if not in adaptability. Both are subject to extensive psychological and cognitive conditioning, and are physically and mentally reworked to render most of their baser drives inert and their beings rechannelled towards aggression, goal acquisition and the fulfillment of duty, and as a further safeguard against distraction and as a biological control, both are of course incapable of procreation. In both cases all that is left are beings of singular purpose; in the case of each Astartes, what is created is a living engine of conquest that cares for little else, and in the Custodian Guard, each is created protector of unrelenting diligence and savage capability -- a watchman whose vigilance will never tire.

What also differs truly between the two, Custodian Guard and Space Marine, is not just their functional purpose, but the extent of their augmentation and the means by which it is accomplished. While the process through which the Adeptus Astartes are fabricated from a human being is well-enough documented in its outline, though its details are, of course, rightly held secret by those parties involved in the process on a Chapter by Chapter basis, genuine facts about the manner in which the Custodian Guard are created are very few, even within the hands of the Imperium's hierarchy. This is because -- as with all else about the Custodian Guard -- it is a matter for the Imperial Household alone, and that authority is one none may gainsay or question. What is known, however, marks them as different. Firstly, there is the matter of the age of the candidacy. For a child to become one of the Adeptus Custodes, it is known that they must begin the process in their late infancy and certainly before adolescence has taken hold on their physical structure. This stands in stark contrast to the Space Marines whose implantation is only possible after adolescence and best served before full physical maturity. This may link to a second of the few known facts about the creation of the Adeptus Custodes: that the gene-craft and alchemistry that transforms them is as absolute as it is subtle, and worked upon the smallest conceivable microscopic level of their genome and cellular structure. It is a process that effects such change on the mortal human form that, when complete, unless they suffer such massive bodily harm as to forcibly end their lives, they are effectively immortal, without perceptible ageing taking place after full maturity.

Not then for the Adeptus Custodes the pattern of surgical grafting and organ implantation that creates a Space Marine, no such crudities of augmentation at all mar the Custodian; what creates them is as invisible as it is potent, worked upon the core genetics and at a deep cellular level, and perhaps tailored to each specific inductee. There are those who insist that so invisible and yet so powerful this process is that it crosses over into a metaphysical realm of biomancy and psychic manipulation on a level unguessed at. Given that it is said that the Emperor Himself has overseen the creation of every single Custodian Guard who has ever lived, this may well be true. The peerless warriors who then result from this arcane process are a rare breed indeed, and not to be squandered recklessly on the battlefield. They were created with a single purpose in mind; to be the Emperor's own elite guard. They were a force created both to defend the Emperor from physical harm wherever the Great Crusade might take Him, to stand watch over His private domains and most guarded secrets, and to serve as the direct agents of His will -- as His personal emissaries -- be that will to protect, to venture, to claim, to keep secret, or to execute without remorse.

Role and Capabilities
The Custodes are warriors unmatched in the galaxy, genetically-engineered by the Emperor Himself. The Emperor engineered few of these warriors once the swifter method for creating superhuman warriors using Space Marine gene-seed became more viable. The martial capabilities of the Adeptus Custodes remain largely unknown at the present time. What is known is that they possess skill beyond even a "normal" member of the Adeptus Astartes. It has been said that the Adeptus Custodes are to the Emperor what the Space Marines are to the Primarchs; that the Emperor's own genetic matrix was used in their creation and through this their loyalty to Him is assured. Others argue that the Custodians are not like the Emperor in the way that a Space Marine is like his Primarch, and that some other source was used as a template for their physical and psychological form; a source that was lost during the anarchy of the Age of Strife. The truth will likely never be known. The Adeptus Custodes are similar to the Grey Knights, the elite Chamber Militant of the Ordo Malleus branch of the Inquisition, in that both are elite, secret organisations with close genetic ties to the Emperor. Custodes are unique as they have neither a known Primarch nor do they use Astartes gene-seed to produce their genetic modifications. They stand a full head taller than a Space Marine and it is said that they were almost the same size as a Primarch. In fact it was said that Constantin Valdor, Captain-General of the Legio Custodes and Chief Custodian to the Emperor during the Horus Hersey, was the same size as the Traitor Primarch Alpharius of the Alpha Legion.

Only 300 Custodes serve as the actual personal guard of the Emperor, called the Hataeron Guard, the Companions of the Emperor, who guard the Emperor's chambers at all times. These are the Custodes that are privileged enough to be in the Emperor's physical presence. The Companions fall under the command of a Tribune, one of the Custodian Tribunate; a senior cadre that formerly consisted of ten in number, forming the Adeptus Custodes' council of war and policy. In the matters of the security of the Imperial Palace's inner sanctums and the person of the Emperor, no higher authority existed. In rank below the Tribune can be found the Centurions or Shield Captains. Each unit of Companions is led by a Centurion. It was one such Centurion that led a small group of Companions to meet Alicia Dominica, head of the Brides of the Emperor (later the Sisters of Battle) during Goge Vandire's Reign of Blood in the Age of Apostasy during the 36th Millennium.

One of the Companions, Constantin Valdor, was the Captain-General and Chief Custodian of the Legio Custodes during the Horus Heresy. He was the most honoured of all of the Emperor of Mankind's creations. No other being had served the Emperor for as long as he, save for the Imperial Regent of Terra, the potent psyker Malcador the Sigillite. Valdor was a proud and respectful warrior unmatched in his devotion and loyalty to the Emperor. Valdor was ever-present at the Emperor's side, always protecting Him from unseen enemies and he saved the Emperor's life innumerable times. Along with Malcador, Valdor was the Emperor's most trusted friend and advisor.

Constantin Valdor was one of the first High Lords of Terra chosen after the end of the Horus Heresy to guide the Imperium forward following the Emperor's internment within the Golden Throne. He also had a close relationship with the Primarchs Rogal Dorn and Leman Russ, although initially Russ and Valdor did not see eye to eye. Dorn was ever-present at the Imperial Palace during the Great Crusade and so Valdor and the Primarch spent much time together. On the other hand, Valdor only earned Russ' respect when the former defeated Horus in a sparring match. The two then served together in combat during the Fall of Prospero when the Custodes and the Space Wolves joined to punish the Thousand Sons Legion of Magnus the Red for his continued use of sorcery despite the edicts of the Council of Nikaea. There is no record of when or how Valdor was killed or if he was even killed at all. He eventually stepped down from the Senatorum Imperialis as a High Lord so that he could continue to devote all of his attention to protecting his beloved Emperor, now encased within the Golden Throne.

However, other accounts of the Custodians' exploits provide a different version of the relationship between the Astartes and Custodes. These records indicate that though the Custodians are slightly larger, on average, than Space Marines, their fighting skills are more or less equal. While Space Marines don their armour ritually and in the presence of their squadmates in order to focus themselves entirely on their martial calling, Custodians arm themselves alone and in silence, reflecting on the varied duties they must perform in the service of their master. As bodyguards, the Custodes not only protect the Emperor's person but also maintain scrupulous surveillance on all the other factions of the Imperium to police their loyalty, infiltrate the households of suspicious individuals among the Imperial nobility, and enter deep cover to test the strictness of their own security within the Imperial Palace, exercises which are called Blood Games. Additionally, these records also confirm that each Custodian's name consists of numerous components typically awarded for feats of arms; Valdor's full name, for instance, is over nine hundred components long.

Magisterium and Misericordia
One of the singular features of the ancient Adeptus Custodes as an organisation, and the power of its individual Custodians, is their place in the scheme of the Imperium's law. While an accredited Imperial Planetary Governor is effectively tyrant of their own world within the edicts and parameters of wider Imperial law, and few would gainsay the Adeptus Astartes in any demands they were to make, the Adeptus Custodes are alone officially afforded the power of the Magisterium Lex Ultima in the high form, which is to say they are beyond all law and all command save for the direct authority of the Emperor Himself. In addition to this, each one is a lord of the Imperium in their own right. This fact is symbolically represented not only by the right to still carry the single-headed raptor and lightning bolt heraldry of the Unification Wars campaign, but also by the carrying of the Misericordia.

For long centuries of unbridled internecine carnage on Ancient Terra during the Age of Strife, the Blade of Mercy or Misericordia came to represent the complete power of life and death the warlords held over the mass of humanity which toiled beneath their yolk and suffered at their whim. From the dust wastes of Ursh to the Manakonite Temples of the No'rad ice hive, the bearing of such a blade, usually in the form of a long dagger or short sword made to perpetrate a single, killing thrust, came to symbolise the dread authority of the executioner-judge. Beyond the power it represented, the Misericordia might also be used in practice to carry out a "clean" sentence of death on a transgressor, or to offer terminal surcease to a warrior grievously wounded in battle at their master's discretion, in either case living up to its name as an agent of mercy as well as death. When the Emperor came to mastery of Terra and ended the bloody cycle of the warlords' reign, His agents and judges, and only they, came to carry the Misericordia as His mastery eclipsed all others, and it is a tradition the Adeptus Custodes still uphold.

When an aspirant ascends to the ranks of the Adeptus Custodes, he is presented with a beautifully fashioned knife known as a Misericordia. These weapons are filigreed with gold and theldrite, their hilts moulded to the owner's unique grip and their blades imbued with micromolecular dissonator spirits that allow them to slice through the thickest armour as though it wasn't there at all.

More than a lethal sidearm, the Misericordia signifies something greater. As the Emperor led His wars of unification, his Custodians are believed to have co-opted the term for their own use. No longer would the Misericordia be a symbol of tyrannical rule. Instead, it came to represent the right of the bearer to act as the arbiter of the Emperor's judgement, and to put to death those tyrants, lunatics and demagogues who stood against Him.

The Misericordia still shows its wielder to be the Emperor's sanctioned executioner, yet since his fall these blades bear a second, grimmer meaning. They have become weapons of vengeance, to be turned upon those who betrayed the Emperor and left Him a broken shell. Every time a Misericordia is plunged into a traitor's heart, so it is said, a minuscule measure of revenge is exacted on behalf of the Emperor Himself. Though the Custodians are typically immune to such superstition, there are those amongst their ranks who harbour the hope that if enough traitor blood is spilt with these blades, it may in some way restore their master. Another school of thought, the adherents of which are known as the Miserians, believe that through the wounds inflicted with Misericordia they will slowly bleed the great descendants of Horus, inflicting a death by a thousand cuts upon the Black Legion and their masters. Thus, though Custodians have the right to carry their Misericordia or not as they see fit, it is rare indeed that they go to battle against the Heretic Astartes without these blades at their hips.

Arms and Armour
Since ancient times, the Adeptus Custodes' panoply of arms and armour, its wargear and even the vehicles and support systems it employed are often unique to the Adeptus Custodes and them alone. Whether ancient relic or newly-made, these items were not only customised exactly to task, but were also produced without any regard to the consumption of resources or rarity of component or lore required; to arm and outfit the Legio Custodes to the optimum, nothing was spared.

This supremacy is evident from the auramite alloy-reinforced armour the Custodian Guard wears, each a planet's ransom in worth, to the plethora of repulsor-lift grav-vehicles under their control, most of which were derived from designs brought back by the great technoarchaeologist Arkhan Land and forbidden for use by any other. Likewise, their singular weapons, be they blade or Bolter, are masterworks, produced by entire sequestered sub-cults of the Adeptus Mechanicus and clades of hereditary artisans beholden to no other and tasked alone in the Adeptus Custodes' provision.

Entire bloodlines of exceptionally skilled artisans dwell within gilded towers on Terra, their purpose to fashion the auramite armour and perfectly balanced weapons for each new Custodian. Certain names such as the Clan Halbrinmir or the Clan Gestaxtis are renowned for their martial masterworks, and their augmetically enhanced artisan-barons are famed for the wonders they have wrought.

Even greater than these resources at their disposal is the Custodian's ability to draw upon any facet of the Imperium's war machine and uncounted hosts it needed to meet its ends, extending its potential power to unguessed-at-levels. The Adeptus Custodes have access to an incomparable armoury of technology, much of it dating back thousands of years. From the sleek Dawneagle Jetbikes of the Vertus Praetors and the magnificent Allarus-pattern Terminator Armour, to Land Raiders and Contemptor Dreadnoughts that saw battle during the Great Crusade, such equipment epitomises the proven excellence of all Adeptus Custodes materiel. The tools of war wielded by the Emperor's guardians never fail or falter, for they are handmade by the Imperium's most skilled smiths and maintained to the most painstaking standards imaginable. Just as the warriors who protect the Golden Throne must be utterly without fault or weakness, so must be the equipment they rely upon to discharge their duties.

The reason for this supremacy above all in arms is a simple one, for not only are the Adeptus Custodes fitted to match any potential threat from without, but also from within, and a clear demarcation was enforced between the potency of the Custodes' arms, and those of any other Imperial forces, not least of all the Space Marines, who they already overmatched in physical might. It is perhaps one of the great questions of lost history: what might have been in the wars of the Horus Heresy had the Legio Custodes not been so heavily waylaid by the disastrous consequences of Magnus' great sin on Terra and more able to take an active hand, had not so many of them been trapped for years in a terrible parallel war all but entirely hidden from the eyes of the cosmos? But that is a darker tale yet, and the weighty duty of a different record than this to tell.

These incredible armaments, the endless training regimes that the Custodians undergo, the years-long holo-conflicts through which they battle, and the shadow-shrouded wars they fight in the Emperor's name throughout the Sol System and far beyond – all these factors ensure that the Ten Thousand are the finest fighting force in the entire Imperium.

At Present
Before the Emperor's internment within the Golden Throne, the Custodes had access to some of the most advanced wargear within the armouries of the Imperium. However, in the years between the Horus Heresy and the birth of the Great Rift, they took a far more limited role in Imperial affairs, and almost never left Terra and only very rarely left the Imperial Palace. It is unknown how limited the Custodes' wargear choices are due to the unknown workings of this elite and reclusive paramilitary specialist force that remains an organisation apart from the rest of the Imperium. They would also more than likely remain aloof in regards to the composition of their wargear and equipment as well as their overall tactical capabilities. Whenever they Custodians are seen outside the walls of the Imperial Palace, as rare as that was, it was in their martial aspect. Mortals would fall on their faces as if before gods. To them, these gold-clad transhuman warriors seemed as if they were wrath incarnate, created for destruction and nothing else. But this was far from the truth, for the Custodes were the Emperor's companions once, the ones in whom He confided, acting as His counsellors and His artisans.

The Custodes had been created to be the guardians of a new age and were charged to be strong enough to keep it secure. But in this sacred duty they failed. Following the internment of the Emperor into the Golden Throne after the defeat of Horus on his flagship during the Battle of Terra, the Custodes outwardly wore the mark of their failure in the black robes that covered their auramite. It was a permanent reminder, replacing the traditional cloaks of blood-red that once adorned their battleplate. It weighed heavy with every Custodian, for they knew more of the nature of the fall than most. This bleak colour change reflected that the Custodians were in permanent mourning for failing to protect the Emperor in His hour of need. But with the return of the Avenging Son, the resurrected Primarch Roboute Guilliman, the Adeptus Custodes have cast off their black cloaks and now don their crimson cloaks of old. Taking to the sea of stars, they now bring the battle to the Great Enemy, intent on absolving themselves in the baptism of fire and blood for their failure in their duties ten millennia earlier.

1st Edition
In Rogue Trader (1st Edition) the Custodes were the Guardians of the Emperor and the Imperial Palace. They wore simple but effective clothing: boots, leather breeches and a black cloak, their torsos naked and corded with tattooed muscle, and they carried laser-tipped halberds said to have been built to resemble the traditional Guardian Spears. Their helms were tall and ornate works of art, giving the Custodes a threateningly impassive appearance. They were considered superior to the Astartes of the time, although not as loyal to the Emperor. Clearly, this version of the Custodes has long since been superseded in current canon.

Uniforms and Heraldry
Each Custodian's armour and weapons are crafted specifically for them by hand. Thus, each suit of Power Armour is an individual work of exceptional craftsmanship with its own unique flourishes and decorations. Yet all Custodians maintain certain standardised elements to their wargear that help them to quickly identify one another’s place both on and off the battlefield. The numbers below correspond to the image at right.
 * 1) The right shoulder guard of a Custodian's armour depicts the Imperial Aquila, a sigil of eternal vigilance and a sign of the Custodian's mandate to enact -- by force if necessary -- the will of the Emperor Himself.
 * 2) The gems set into each Custodian's armour are individually mined from deep beneath the surface of Terra and hand-cut by skilled artisans. Their colouration is flawlessly precise, an art form in its own right, not only across the Custodian's armour, but across that of his entire Shield Company. When a Custodian switches from one such organisation to another, the stones will be carefully extracted from his armour and replaced with those of an appropriate colour if needs be.
 * 3) The colour panels on the Custodian's left shoulder guard show clearly to which Shield Company or Shield Host they belong. The latter organisational tier takes precedence for these purposes. This colouration will often match the Custodian's tabard, along with any robes he may wear.
 * 4) All Adeptus Custodes armour is made from the incredibly rare substance known as auramite. Its natural colouration is a lustrous gold, a hue entirely appropriate for the Emperor's personal guardians. However, through closely-guarded alchemical processes, auramite can be tinted, or its colour changed altogether on a molecular level. It is a painstaking and costly process, but considered far more suited to the Custodians' importance than simple repainting.
 * 5) The haft or hilt of a Custodian's weapon -- in this case a Guardian Spear -- is sometimes worked -- or, in many cases, reworked -- to match the colouration of their armour. This is not standard amongst all Shield Companies, however.

Great Crusade & Horus Heresy Eras
"There are no bystanders in the war of life and death, no place the battle cannot reach; so fight it without remorse or relenting, for death will surely do the same."

- Attributed to Captain-General Constantin Valdor


 * Constantin Valdor - Constantin Valdor was the Chief Custodian and Captain-General of the Legio Custodes during the Great Crusade and the Horus Heresy. Just prior to the outbreak of the Horus Heresy, Valdor was charged by the Emperor to accompany the Primarch Leman Russ of the Space Wolves in bringing the Primarch Magnus the Red of the Thousand Sons to account for breaking promises he had made during the Council of Nikaea which had strictly forbidden the use of sorcery and psychic powers within the Imperium. Valdor, with a contingent of the elite Custodian Guard, fought alongside Russ and the Space Wolves during the Fall of Prospero. He and his forces were responsible for killing at least three of the greatest psykers of the Thousand Sons Legion and routing a force much more numerous than their own. He was also responsible for saving Bjorn the Fell-Handed when his arm was corrupted by the sorcerous powers of a Thousand Sons psyker. Valdor sliced Bjorn's arm off to prevent the corruption from overrunning his body. After Horus' betrayal became known to the Imperium, Valdor was present during the meetings of the Officio Assassinorum's Clade Sires and Siresses. It was Valdor who suggested that an Assassin from each Clade operate as a team to assassinate Horus, rather than act alone as was the standard mode of operation. It is said that Constantin Valdor epitomised all that it means to be one of the Adeptus Custodes. Stoic, watchful, fiercely intelligent and -- when required -- a truly inspirational leader, Valdor was a true hero of the Imperium who never once faltered in his duty. It is not recorded what became of Valdor after the Emperor's internment in the Golden Throne, but there are those who believe he serves the Emperor still...
 * Mikaelor Cobernus - Cobernus was a Shield-Captain of the Legio Custodes during the 31st Millennium.
 * Ra Endymion - Ra Endymion was a Tribune of the Legio Custodes during the Horus Heresy and the commander of the Custodians who fought in the Imperial Webway War. He was born on Terra during the Unification Wars to Koja Zu, the Minister of the Anuatan Steppes, around the time of the Battle of Maulland Sen. Ra's father was executed by Constantin Valdor for the high crime of stealing Terra's last remaining ocean when Ra was only four years old. He was then taken by the Legio Custodes as a potential candidate. The young boy received his name 'Ra' in honour of the ancient Gyptian sun god and eventually rose to become the leader of Squad Dynastes, who were later dubbed the Lords of Terra by the Emperor Himself. This squad was composed of twenty sons and nephews who had been taken as tributes from various defeated Terran rulers and warlords. By the opening years of the galaxy-wide conflict known as the Horus Heresy, Ra had earned eight-hundred and seventy-one names in honour of valorous deeds and was raised to the rank of Tribune. Following the Crimson King's folly, when he tried to warn the Emperor through sorcerous means, the wards placed on the Imperial Webway deep within the Imperial Palace's dungean were breached, which allowed the legions of Chaos to encroach upon the Emperor's Palace. Five years into the war, things began to go badly for the Imperial forces, as the neverending legions of Chaos threatened to breach the sanctity of the Palace's dungeons. With the deaths of both Tribunes Kadai Vilaccan and Jasac, Ra Endymion was given sole command over the Custodian fighting the war within the Imperial Webway. When the derelict city within the webway known as Calastar (also known as the 'Impossible City') fell to the invading daemonic hordes, the Emperor finally left the Golden Throne in order to cover the retreat of the decimated Imperial forces and to confront the Daemon Drach'nyen. Taking the form of a Stone Epoch war-chief, he impaled the Emperor, claiming that it would be His death. But the Emperor tore the daemon, now in the form of a great daemonic sword, from His body and with armour-boosted strength and powerful telekinetic force, He hurled it from His grip at Ra. The sword impaled the Custodian causing the daemon to be bound within him. The sword quickly disappeared, for it was now bound within the Custodian's body, caged within Ra's flesh. The daemon within him could not be killed, not even by the Emperor Himself, only imprisoned. As the last remaining Imperial forces retreated from the webway, the Emperor ordered Ra to run deep within the myriad tunnels of the webway as far as possible. Ra's ultimate fate is unknown.
 * Kadai Vilaccan - Kadai Vilaccan served as a Tribune of the Legio Custodes during the Horus Heresy in the 31st Millennium. He fought and eventually died five years into the fighting during the Imperial Webway War only two weeks after the death of Tribune Jasaric.
 * Jasaric - Jasaric, known also as Jasac, was a Tribune of the Legio Custodes during the Horus Heresy in the 31st Millennium. He had the honour of being one of the original thirty Cudtodians created by the Emperor of Mankind, and had fought by his liege's side since the Terran Unification Wars, and was present during the Battle of Maulland Sen. He fought and eventually died during the fighting in the Imperial Webway War. He was succeeded by Tribune Kadai Vilaccan.
 * Helios - Helios served as a Tribune of the Legio Custodes during the Horus Heresy in the 31st Millennium. He fought and eventually died during the fighting in the Imperial Webway War. He was succeeded by Tribune Jasaric.
 * Ixion Hale - Ixion Hale served as a Tribune of the Legio Custodes during the Horus Heresy in the 31st Millennium. Hale's ultimate fate is unknown.
 * Diocletian Coros - Diocletian Coros was a Prefect of Hykanatoi and served as a part of the Legio Custodes during the Great Crusade and Horus Heresy in the 30th and 31st Millennia. He fought in the Imperial Webway War under the command of Tribune Ra Endymion. He was charged with organising a fresh wave of Imperial forces to resist the encroaching Forces of Chaos, which included the condemned prisoners of the fallen Imperial Knight House Vyridion, who would aid the beleaguered Imperial forces at Calastar just as the Chaos hordes began to overrun it. During this final epic battle, Diocletian fought at the sides of both Ra Endymion and the Emperor Himself, and eventually fought their way back to Terra and escaping the confines of the Imperial Webway just before the Emperor sealed the portal, effectively ending the war within the webway. Following the battle, the Emperor began to show Diocleitan visions of both His and Terra's past, as much as he had done with Ra. This could be an indication that Diocletian was raised to the status of Tribune following Ra's disappearance into the webway. Diocletian's ultimate fate is unknown.
 * Aquillion - Aquillion served as the Occuli Imperator, the "Eyes of the Emperor", the Custodian who was assigned to watch over the Primarch Lorgar and his Word Bearers Legion after they were found to have violated the Emperor's trust during the Great Crusade by spreading their belief that the Emperor was a God to newly conquered human worlds. Aquillion and a team of four other Custodians (Vendatha, Sythran, Nirllus and Kalhin) were assigned to the Word Bearers Legion after that Legion's humiliation on the world of Khur and the destruction of that planet's capital city of Monarchia by the Ultramarines Legion on the order of the Emperor. Aquillion used a two-handed Power Sword in combat rather than the standard Guardian Spear. Aquillion and his four-man-team were all eventually slain by the Word Bearers so that they could not inform the Emperor of Lorgar's betrayal. The leader of the daemon-possessed Gal Vorbak, Argel Tal, decapitated Aquillion by biting his head off.
 * Kalhin - Kalhin was one of the four other Custodians assigned to serve under the command of Aquillion to watch over Lorgar and the Word Bearers. While attempting to kill the traitor Cyrene Valantion, Kalhin was shot down by Incaradine, the mechanical Conqueror Primus of the 9th Maniple of the Carthage Cohort of the Legio Cybernetica.
 * Nirallus - Nirallus was one of the four other Custodians assigned to serve under the command of Aquillion to watch over Lorgar and the Word Bearers. Amongst his fellow Custodes and the warriors of the Word Bearers, Nirallus was considered the "swordmaster" for his skill with his Custodian Spear. He used this skill to slay Malnor, one of the strongest of the daemon-possessed Gal Vorbak, but was torn apart seconds later by two other members of this warrior elite of the Word Bearers Legion.
 * Sythran - Sythran was one of the four other Custodians assigned to serve under the command of Aquillion to watch over the Primarch Lorgar and the Word Bearers Legion. He was part of the elite Squad Dynastes, called the Lords of Terra by the Emperor Himself, which comprised twenty souls, each one a scion of an extinct royal Terran bloodline, taken as tribute in conquest during the Unification Wars and inducted into the Ten Thousand. Before leaving Terra to watch over the Word Bearers Legion for 50 standard years as part of the XVII Legion's punishment for violating the Imperial Truth during the Great Crusade, Sythran swore an oath that he would not speak again until he set foot on Terra once more with this duty complete. He kept this promise until the moment of his death at the hands of the Gal Vorbak, when he mocked the Word Bearers' Chaplain Xaphen just after killing him for his betrayal of the Emperor.
 * Vendatha - Vendatha was one of the four other Custodians assigned to serve under the command of Aquillion to watch over Lorgar and the Word Bearers. Vendatha was used as the tenth sacrifice to summon Ingethel, the daemonic Emissary of the Chaos Gods.
 * Zerin - Zerin was a participant in a "Blood Game" alongside Amon, Haedo and Brokur. Out of the four, Zerin did the worst, as he did not even make it into Imperial Territory before he was caught by his fellow Custodians in the city of Irkutsk.
 * Iacus - Iacus was one of the 15 Custodes sent to watch over the Word Bearers Legion who was not assigned to watch over the Primarch Lorgar with Aquillion. Iacus and his fellow Custodes watched over First Captain Kor Phaeron and First Chaplain Erebus instead. Before the Word Bearers' treachery came to light, Iacus and all his Custodes had fallen in battle alongside the Word Bearers, never knowing of their betrayal.
 * Arcatus Vindix Centurio - When on Terra the Emperor Himself imprinted the genetic knowledge of the Primarch-programme onto Corvus Corax, he also ordered a squad of his very own bodyguards to accompany the Primarch of the XIXth Legion back to Deliverance to protect the sensitive knowledge. Although the knowledge imprinted into Corax's mind would slowly fade, the Custodes would continue their Emperor-given task to protect and watch over the Primarch of the Raven Guard. As leader of this new bodyguard and the man whose task it had been to watch over the Raven Guard during their stay in the Imperial Palace, Arcatus Vindix soon became a figure of influence within Corax’s war council, as the Raven Lord enjoyed debating with the leader of the Custodians when not on the front lines or even in the heat of battle. Whereas Corax always marvelled on Horus' temerity to declare war on the Imperium, Arcatus had a quite different point of view -- Horus would never have turned traitor if he hadn't been sure from the beginning that he would win. Alongside the ever-active Raven Guard, Arcatus and his brothers saw much combat, participating in such venture as the Raid on Kapel-5642A or the Day of Vengeance on Carandiru.
 * Brokur - Brokur took part in a "Blood Game" alongside Amon, Haedo and Zerin. Brokur emerged as the runner-up in the contest as he made it to The Hegemon before he was caught. Valdor had not expected anyone to get closer to the Imperial Palace than Brokur, but Amon succeeded in infiltrating the Palace itself.
 * Saturnalia Princeps Carthagina - Saturnalia was a member of the Legio Custodes during the Horus Heresy era. He was assigned to the Psi-Hunter Team charged with the task of capturing the Outcast Dead -- the surviving members of a small Legiones Astartes honour guard known as the Crusader Host that was stationed on Terra. The fugitive Astartes were members of the Traitor Legions that had sided with Horus in his rebellion against the Emperor during the Horus Heresy. They had been imprisoned in the maximum security prison known as The Vault since they could no longer be trusted, but they managed to stage a break-out and escape. Saturnalia became part of the hunt team led by the Seer Hunter Yasu Nagasena to track down the Outcast Dead in an attempt to regain his honour after letting the Outcast Dead take his prisoner, the Astropath Kai Zulane. During the final battle with the Outcast Dead in the Temple of Woe, Saturnalia managed to kill Subha, a World Eaters Berserker. Subbha's twin, Asubha, attacked him and drove a Custodian Guardian Spear through Saturnalia's head, just as Saturnalia managed to stab Asubha in the heart with his own Guardian Spear.
 * Haedo Emankon - Haedo Emankon took part in one of the many "Blood Games" alongside Amon, Zerin and Brokur. Of the four participants in the contest, Haedo was the third most successful, as he made it to Cebu City before he was caught. Haedo Emankon was later charged by Constantin Valdor to gather incriminating evidence on a member of the government of unified Terra who was suspected of treason against the Emperor alongside Amon Tauromachian.
 * Khorarinn - Khorarinn was a member of the Legio Custodes during the Great Crusade and Horus Heresy eras. Following the Istvaan III Atrocity, Khorarinn was assigned to work alongside the Knight-Errant, Agentia Primus Nathaniel Garro, a former Battle-Captain of the traitorous Death Guard in determining the loyalty of a ragtag refugee fleet that sought sanctuary within the Segmentum Solar. They were led by the loyalist World Eaters Captain Macer Varren. Khorarinn was highly suspicious of Varren's motives as well as Garro, as they were both formerly members of known Traitor Legions. Further tension was built up between Garro and the Custodian when the latter threatened to kill Tylos Rubio should he utilise his psychic powers in direct violation of the Emperor's Decree Absolute, as laid down during the Council of Nikaea. Ironically, he showed respect towards the White Scars Captain Hakeem, an unexpected member of the refugee fleet, who turned out to be a traitor who was loyal to the Warmaster. Ironically, Hakeem and his traitorous White Scars would eventually go on to kill Khorarinn as those whom the Custodian accused of disloyalty attempted to save his life.
 * Amon Tauromachian Leng - Amon Tauromachian was a member of the first circle of the Legio Custodes during the Great Crusade and Horus Heresy in the 30th and 31st Millennia. Amon was present during the Triumph of Ullanor, where Horus Lupercal was invested by the Emperor with the title of Imperial Warmaster and command over all the Imperium's armed forces and overseeing the final stages of the Great Crusade. When he was manning a checkpoint alongside a fellow Custodian, Haedo Venator, as well as seven Null-Maidens of the Silent Sisterhood, Primarch Magnus the Red was impressed by Amon's stoicism and dedication and predicted that there were great things ahead for him. Many years before the start of the Heresy, Amon was present at the Council of Nikaea to watch over the trial of Magnus the Red for his use of sorcery. Whilst protecting Kasper Hawser, a skjald of the Space Wolves, Amon was attacked by a minion of Chaos in the disguise of a Thousand Sons Space Marine, but managed to survive the encounter thanks to the efforts of the Astartes of the Space Wolves. Amon was later charged with protecting the Emperor when Terra began the process of fortification to withstand the coming assault by the Warmaster Horus and his Traitor Legions. After news of Horus' betrayal reached Terra, Amon was tasked with taking part in the "Blood Games", a rite all Custodians endured and one which set them against the formidable defences of the Imperial Palace in the hope of improving the Custodians' defence of the Emperor through the exposure of flaws in his protection. Following his success in the "Blood Games", Amon Tauromachian and a fellow Custodian Haedo Emankon were sent on a dangerous mission by Constantin Valdor, the Chief Custodian, to gather incriminating evidence on a member of the government of unified Terra, who was suspected of treason against the Emperor. Amon would go on to be regarded as one of the greatest members of the Legio Custodes. His ultimate fate is unknown.
 * Sumant Giri Phalguni Tirtha - Tirtha was a Veteran Custodian, whose name was said to bear at least seventy-six awarded titles. He was one of the gaolers at the high security Imperial prison on Terra known as The Vault. It was not known how Tirtha had come to Khangba Marwu. He bore no obvious injury and was in prime physical condition, but rumour said he had once questioned an order from the Captain-General, Constantin Valdor. Tirtha was charged with the duty of guarding an extremely dangerous group of prisoners known as the Outcast Dead, the remnants of the Astartes honour guard known as the Crusader Host that was stationed on Terra whose parent Legions had turned Traitor and sided with Horus. Tirtha was killed during the Outcast Dead's successful escape attempt from The Vault, when Atharva of the Thousand Sons took control of an elite soldier with a Plasma Gun and made him shoot Tirtha in the stomach.
 * Uttam Luna Hesh Udar - During the Horus Heresy era Udar was the lead gaoler of the subterranean high security prison built to detain those individuals deemed hostile to the Emperor and isolated from the world above. Built beneath the Himalayan peak known as Rakaposhi, only the most senior Custodians bothered to use its original name, Khangba Marwu, and for those condemned to its cells, who would never again see the light of day, it had an altogether more prosaic name. They knew it simply as The Vault. Udar was removed from the fighting ranks of the Legio Custodes after being exposed to an Ork bacteriological pathogen, whose aftereffects greatly reduced his reflexive response times to a level below the minimum required for front line service amongst the Custodians. A proud man, he took his removal from the front lines hard, but eventually adapted and took to his new role as a gaoler at The Vault with the same determination and attention to detail that had seen him come the closest to the full infiltration of the Imperial Palace in the Blood Games until his peer Amon Tauromachian Leng bested him. During his tenure, Udar was charged with watching the last remnants of The Outcast Dead -- a small group of Astartes warriors drawn from the Traitor Legions that were the last of the Crusader Host, an honour guard of Space Marines comprised of representatives from each of the 18 Space Marine Legions that served on a rotational basis within the Imperial City outside the Imperial Palace on Terra. Udar met his ultimate fate when The Outcast Dead engineered a successful escape attempt. Udar was slain when he confronted one of the berserker World Eaters Astartes in close combat. The berserker in question, Sergeant Tagore, ripped out a section of Udar's spine through his chest, just as Tagore had promised he would during his confinement.
 * Sagittaras (Sagittarus Malacque) - Sagittarus was one of the first thirty Custodians created by the hand of the Emperor of Mankind and served alongside his liege as His personal Honour Guard during the Terran Wars of Unification. Choleric and wild, he was the first Custodian to be wounded unto death, and interred within the sarcophagus of the Contemptor Pattern Dreadnought as a part of the Legio Custodes Moritoi.
 * Primarus - Primarus was a Custodian who had been interred within the adamantium sarcophagus of an unknown model of Dreadnought, to continue fighting on behalf of the Emperor during the Great Crusade and Horus Heresy eras. His ultimate fate is unknown.
 * Senitorus - Senitorus was a Custodian who had been interred within the adamantium sarcophagus of an unknown model of Dreadnought, to continue fighting on behalf of the Emperor during the Great Crusade and Horus Heresy eras. His ultimate fate is unknown.
 * Gathas - Gathas was a member of the elite Squad Dynastes, called the Lords of Terra by the Emperor Himself which comprised twenty souls, each one a scion of an extinct royal Terran bloodline, taken as tribute in conquest during the Unification Wars and inducted into the Ten Thousand. He fought and eventually died during the fighting in the Imperial Webway War under the command of Tribune Ra Endymion.
 * Mycorian - Mycorian was part of elite Squad Dynastes, called the Lords of Terra by the Emperor Himself which comprised twenty souls, each one a scion of an extinct royal Terran bloodline, taken as tribute in conquest during the Unification Wars and inducted into the Ten Thousand. He fought and eventually died during the fighting in the Imperial Webway War under the command of Tribune Ra Endymion.
 * Juhaza - Juhaza was part of elite Squad Dynastes, called the Lords of Terra by the Emperor Himself which comprised twenty souls, each one a scion of an extinct royal Terran bloodline, taken as tribute in conquest during the Unification Wars and inducted into the Ten Thousand. He fought and was badly injured during the fighting in the Imperial Webway War under the command of Tribune Ra Endymion. Juhaza's ultimate fate is unknown.
 * Solon - Solon was part of elite Squad Dynastes, called the Lords of Terra by the Emperor Himself which comprised twenty souls, each one a scion of an extinct royal Terran bloodline, taken as tribute in conquest during the Unification Wars and inducted into the Ten Thousand. He fought in the Imperial Webway War under the command of Tribune Ra Endymion. Solon's ultimate fate is unknown.

Post-Heresy Era

 * Trajann Valoris - Trajann Valoris is the current Chief Custodian and 17th Captain-General of the Adeptus Custodes and perhaps the deadliest individual warrior in the entire Imperium. There are no records in the Imperial databanks on his martial conquests or his ascent into the order. For as long as any living mortal can remember, Valoris' name has been spoken of with nothing short of reverence, for many considered the Captain-General to be the personal representative of the Emperor Himself. Even the High Lords might be mocked, when in wine or in anger, but to do so with the Captain-General was simply beyond imagination. For to mock Valoris was to mock the Emperor Himself. Such blasphemy would not go unpunished, and would inevitably result in a transgressor's untimely death. While the two Tribunes of the Adeptus Custodes were generally occupied with the many ritual purposes of the order, the Captain-General had no set remit, but governed the forces under his command with complete freedom, to the extent that if the Ten Thousand had dealings with any part of the Adeptus Terra, they were carried out through him. Though the Captain-General of the Adeptus Custodes traditionally served among the High Lords of Terra only under the most dire of circumstances, such as during the War of the Beast in the mid-32nd Millennium, it was only the persistence of Chancellor Lev Tieron that persuaded Valoris to assume the seat on the Senatorum Imperialis that had been left vacant for some time following the death of Lord Brach, the Chancellor of the Estate Imperium.
 * Andros Launceddre - Andros Launceddre was the Chief Custodian and 16th Captain-General of the Adeptus Custodes. Launceddre was also the predecessor of Trajann Valoris. During the Years of Madness, possession is revealed amongst a sub-sect of the doomscryers themselves, though not until the false predictions of the fallen psykers send Captain-General Launceddre to his death at the Battle of the Gilded Pyre (later recounted in the Custodian's chronicles as the Battle of Black Pyre). It is amidst this climate of spiralling paranoia and danger that Captain-General Trajann Valoris is elevated to command the Ten Thousand, and he wastes no time in taking steps to regain ironclad control of Terra's defences.
 * Galahoth - Galahoth was the Chief Custodian and 15th Captain-General of the Adeptus Custodes. A notoriously conservative Captain-General, the Adeptus Custodes suffered stagnation under his rule. Galahoth disappeared sometime in the latter years of M40 or early M41, which heralded the so-called Years of Madness, a time of strange omens and ominous whispers that engulfed Terra. There was a study increase in cult activity - both heretical and xenophile - throughout the Sol System, which included the Throneworld as well. He was succeeded by Andros Launceddre.
 * Aesoth Koumadra - Aesoth Koumadra was the Chief Custodian and Captain-General of the Adeptus Custodes sometime between the 33rd and 39th Millennia.
 * Beyreuth - Beyreuth was the Chief Custodian and Captain-General of the Adeptus Custodes during the War of the Beast in the mid-32nd Millennium. During this crisis, he led the Custodian Guard in battle against the Harlequins of the Troupe of Joyful Tears, when they managed to breach the sanctity of the Imperial Palace, intent on personally delivering a message to the Master of Mankind Himself. Only Shadowseer Lhaerial Rey and Death Jester Bho reached the chamber that led to the Sanctum Imperialis, they were able to kill dozens of Custodians, all the while as the Shadowseer insisted that she had come in peace. She explained that she had been sent on behalf of Ulthwé Farseer Eldrad Ulthran to deliver an important message to the Emperor. But the Adeptus Custodes would not relent in their sworn duties, and so, pressed their attack against the xenos interlopers, killing Bho and impaling Lhaerial to the ground with a Guardian Spear. As the Shadowseer continued to insist on meeting with the Emperor, the enraged Captain-General was about to give the order to kill her, until the timely intervention of Inquisitor Lord Veritus saved the Harlequin's life. Using his position as the Inquisition's Representative to the Senatorum Imperialis, Veritus forced Beyreuth to release the Lhaerial to him so that he could interrogate her. After the tragic event known as The Beheading occurred, the de facto rule of the Imperium fell to the sole remaining High Lord of Terra, the Officio Assassinorum's representative, Drakan Vangorish, who reminded Beyreuth of the fact that the Eldar nearly breached the threshold of the Eternity Gate. This argument convinced Beyreuth to join Imperial politics and to take his place amongst the esteemed ranks of the Senatorum Imperialis alongside Vangorich.
 * Heracleon - Heracleon is one of two Tribunes who serves in the Adeptus Custodes of the present era. He serves as the master of the Hataeron Guard, the elite cadre of Custodians who oversees the personal security of the Emperor within the Sanctum Imperialis itself.
 * Italeo - Italeo is one of two Tribunes who served in the Adeptus Custodes of the present era. He commanded the few Custodian forces that were abroad fighting the myriad foes of Mankind in holy warfare. Often, he would be impossible to reach by summons due to the inherent danger inherent in his duties. Following the destruction of Cadia, and the formation of the Great Rift, Italeo was mortally wounded during the Second Battle of Terra, while fighting against a massive incursion by the forces of the Khorne, though he managed to kill one of the Bloodthirsters who was leading them, before his death. Following his death, Italeo was seceded by Maldovar Colquan as Tribune.
 * Maldovar Colquan - Maldovar Colquan is one of two tribunes who serves in the modern era Adeptus Custodes. Maldovar spent many years in service, holding vigil over the Emperor as a member of the elite Hataeron Guard. Following Itaelo's death during the Second Battle of Terra while battling the forces of the Blood God, Maldovar was chosen to replace him as Tribune. Following the resurrection of the Ultramarines Primarch Roboute Guilliman, who was later acknowledged as the acting Lord Regent of Terra, Tribune Colquan served as a liaison between the acting Lord Commander of the Imperium and Captain-General Valdoris. He later joined the assembled Terran forces and took part in Lord Guilliman's Indomitus Crusade, to take the fight to the Archenemy. Tribune Maldovar led the Custodian contingent for well over a century and took part in many notable campaigns, including the Battle of Raukos, which signaled the end of the century-long Crusade. While Colquan served Lord Guilliman faithfully, the Lord Commander could not help but take notice that the Tribune, like many Custodians, had remained superlative individual warriors. But the Adeptus Custodes had rarely served as generals since the old times, and centuries of isolationism had dulled what command abilities they had once possessed. The Tribune's contempt for baseline humanity also troubled Lord Guilliman, a sentiment that was all too often shared amongst Colquan's fellow warrior elite. The Custodians had spent their lives guarding the Emperor, yet they had forgotten who the Emperor guarded in His turn. He chastised Colquan to be more forgiving.
 * Adronitus - Adronitus is a Shield-Captain of the modern era Adeptus Custodes. Following the conclusion of the Terran Crusade, led by the resurrected Ultramarines Primarch Roboute Guilliman, Adronitus confronted the Emperor's son before the Eternity Gate. After making his determination, he permitted Roboute Guilliman to enter within the sanctity of the Sanctum Imperialis to commune with his father, the Emperor. Just before entering the chamber, Guilliman ordered the Custodian Guard to seize Cypher and his fellow Fallen Angels. Adronitus did so, and escorted the Astartes the prisoners to a prison cell within the Imperial Palace.
 * Valerian - Valerian served as a Shield-Captain in the modern era Adeptus Custodes as a part of the Palaiologian Chamber of the Hykanatoi. While taking part in one of the Custodes' Blood Games, he was asked by Heracleon, the Tribune of the elite Hataeron Guard, to join their order. Having long striven to become a member of the Companions, Valerian eagerly accepted this great honour. Led to the Last Door of the Sanctum Imperialis, he prepared himself to face the Hataeron Guard's first trial -- to cross the threshold of the Last Door and enter the presence of the God-Emperor. But after catching a glimpse of the Master of Mankind, Valerian could not compel himself to take a step, for his body refused to obey him. Valerian felt great shame and embarrassment, having failed this first of many trials, and so, he returned to his former duties on the Outer Walls of the Imperial Palace. But he would later make up for his perceived shortcomings, when he helped to valiantly defend the Palace defences during the mayhem and madness that ensued following the aftermath of the formation of the Great Rift, and the subsequent Second Battle of Terra.
 * Ynnades - Ynnades was one of the Adeptus Custodes' Revered Fallen -- a mighty leviathan of the Contemptor-Galatus pattern. The entombed warrior had been roused from his centuries-long slumber when Terra was engulfed by mayhem and chaos, following the formation of the Great Rift. He would later take part in the valiant defence of the Imperial Palace during the Second Battle of Terra against a massive incursion by the forces of the Blood God.

Non-Custodes Personnel

 * Armoury Thrall - Armoury Thralls are mortals who have continued to serve as bonded servants to the Adeptus Custodes since the earliest years of the Imperium. Capable warriors in their own right, they carry extra ammunition and armour sealant for their Custodian masters while they are in battle. Following closely behind them while they perform their duties, when the Bolt Casters built into their Guardian Spears or Sentinel Blades run empty, the Custodians throws the weapon to an Armoury Thrall or casts them into the ground. The Armoury Thrall then proceeds to gather the discarded weapon and reload it and then is strong enough to throw the weapon back to the Custodian.

Standard Wargear

 * Custodian Armour - The panoply of the Adeptus Custodes represents the pinnacle of the armourer's art. Far more sophisticated than production-model Space Marine Power Armour, it is fashioned with rare auramite alloy such as that used for the armour the Emperor Himself wore in battle. Each suit is unique to the Custodian Guard who wears it, and it is fitted with arrays of proximity sensors and Refraction Field generators to further enhance its defences.
 * Praesidium Shield - Ornate precursors to the later Storm Shield, the Praesidium Shields of the Adeptus Custodes are forged from all but indestructible layered Ceramite and resilient alloys reinforced with built-in field generators.
 * Aquilon Pattern Terminator Armour - This is a variant of Terminator Armour uniquely designed to operate in conjunction with the physiology of the Adeptus Custodes. Its origins lie with the Cataphractii suits of the Space Marine Legions, but with far greater power capacity and customised neuro-fibre uplinks, it is said, redesigned by the mind of the Emperor Himself for His elite forces.
 * Teleporation Transponders - Although more often employed in the role of bodyguards and sentinels, when the Emperor was active during the Great Crusade, the Legio Custodes often made use of the teleportarium of their Imperial warships to swiftly gain planetfall. Such mechanisms employed for this were the most advanced of their kind and little was left to chance in their operation.
 * Refraction Fields and Iron Halos - Although relatively rare owing to the resources and arcane lore required to construct them, a variety of personal defence energy shields are nevertheless common in the armoury of the Emperor's direct servants, serving both as a badge of office and a means of protection.
 * Magisterium Vexilla - The ancient icons and standards borne by the Legio Custodes represented the inviolable and nigh-omnipotent authority of the Emperor. In particular was the Magisterium, a seal of ultimate sanction and the might of Mankind. Their mere presence on the battlefield is enough to fill those loyal with resolute zeal and wrack those who face His wrath with fear and dread. Moreover, these banners and icons were also technological artefacts containing Vox relay systems and subsonic inducers, augmenting their battlefield role far beyond the merely symbolic.
 * Arae-Shrikes - Ancient devices of the Dark Age of Technology which twist and distort electromagnetic signals, these counterintelligence devices are considered blasphemous in principle and arcane function by the ancient Mechanicum, and persist only in the hands of the Emperor's retinue. By the use of malifica-djinn and hostile blight-code, they pervert the data-readouts of unshielded Cogitators and telemetry plotters with lying reports and malign falsehood, and what they cannot deceive, they simply blind and deafen with a shrieking multi-frequency cacophony.

Assault Weapons

 * Guardian Spear - The signature weapon of the Adeptus Custodes and in many ways their symbol of office is the Guardian Spear. Elegant and deadly, it is a potent and unique design incorporating a Power Blade and a highly advanced integrated Bolter weapon, and in the hands of a Custodian Guard it can strike and parry at blinding speed despite its size. More rarely, these weapons mount not Bolters but advanced specialised sub-weapons such as compact Meltas or even Adrathic Disintegration Beamers, issued against the deadliest of expected foes. The most beautifully wrought and deadly weapons of the Custodians' arsenal are the Paragon Spears, storied weapons wielded by the most noted Shield Captains and Tribunes among the Ten Thousand.
 * Castellan Axe - A weapon most commonly utilised by Custodian Wardens, a Castellan Axe is a heavy-bladed weapon. These weapons lend themselves to an elegant and brutal combat style that sees the wielder use their exceptional strength in conjunction with their axe's momentum, launching thunderous sweeps that switch direction with breathtaking suddenness to cleave through their victims' guard and hack off heads and limbs. The Wardens can also fire concentrated volleys of bolt fire from the hafts of their weapons, scything down those who attempt to stay out of their blades' devastating reach.
 * Sentinel Warblade - This is another unique weapon of the Adeptus Custodes, brutal where the Guardian Spear is precise. The hyper-pulse disruption field generators found in the warblade are able to tear apart flesh and metal on contact, while built-in to the blade is a double-barrelled Bolter able to lay down a hail of fire at short range.
 * Solerite Power Gauntlets and Power Talons - First fashioned in the pattern of ancient relics to arm the elite of the Thunder Warriors, the Solerite Power Gauntlets and their raptor-taloned variants are potent weapons. They differ from the standard Power Fists and claws utilised by the Adeptus Astartes in both the near-irreplaceable artefact power coils which energise their disruption field generators and the nigh-indestructible materials their casings and blades are fashioned from, forged as they are in furnaces recovered from the ancient Tempest galleries near Terra's molten core.
 * Interceptor Lance - Interceptor Lances are enormous pole weapon with a deadly spear tip, utilised exclusively by the jetbike-mounted Vertus Praetors. Taller end-to-end than an Ogryn, and perfectly weighted, these fearsome weapons boast adamantium blades wreathed in disruptor fields. Vertus Praetors are masters of hit-and-run strikes, driving their lances clean through their precisely chosen targets before ripping them clear again as they speed past. The result is as devastatingly effective as it is explosively gory.

Ranged Weapons

 * Adrathic Weapons - Relics of the Dark Age of Technology believed to be all but unique to Terra, Adrathic weaponry uses a potent but dangerously unstable energy beam to sever the internal bonds of matter, causing objects caught in their path to unravel in a spectacularly destructive manner, leaving only a flaring after-image of what was. Such weapons were legend during the Age of Strife, and devastating wars were fought on anarchic Old Terra solely over the possession of some unearthed cache of Adrathic Weapons and the promise of the power they held. When the Emperor came to dominion and ended Old Night on Ancient Terra, all Adrathic Weapons were given over to Him on pain of death, not simply to the one who retained them but to their entire land and nation such was the importance He placed on controlling this technology. These weapons have remained in His care ever since, and only His own personal weaponsmiths gained and kept the knowledge of how to replicate them in small numbers, much to the jealousy of Mars.
 * Adrastus Bolt Caliver - Developed as a hybrid of later pattern Imperium Bolter weapon designs and Dark Age of Technology "Adrastite" disintegration beam weapons prohibited from general Great Crusade issue, the Adrastus Bolt Caliver is a potent shoulder arm serving as a portable heavy weapon for the Adeptus Custodes. This combination weapon is able to unleash a fusillade of explosive rounds at long range with the potency of the Heavy Bolters carried by the Adeptus Astartes, or at shorter ranges fire a disintegration beam able to rip a target apart at a molecular level, causing its victims to cease to exist in a howling flare of energy.
 * Lastrum Storm Bolter and Bolt Cannon - This pattern of Bolter weapon is named for the weaponsmiths of the Lastrum Core Clan of the Appolyne workshops of Terra. Other than being exemplars of their kind in terms of skill of fabrication, they would not be remarkable save for their uniquely powerful ammunition. Rather than the usual "Kraken" type bolts utilised by the wider sweep of the Adeptus Custodes, the artisans of the Lastrum clans hand manufacture only customised mass-reactive heliothermic warheads for their bolt shells. Once within their target, these burst into brief, but sun-hot incendiary detonations, incinerating their victims from within. These shells are uncommonly dense, requiring a far stronger charge to launch than common bolt shells, and only the Lastrum's uniquely sturdy construction for a weapon of their size can withstand the stresses of their repeated firing. The sheer resources and artifice of these weapons were immense, and they could never hope to be mass produced to arm the Space Marine Legions, and even the output of entire generations of the Lastrum themselves could barely satisfy the Legio Custodes ' demands.

Adeptus Custodes Battlefield Support Weapons
As with much of their personal armoury, the weaponry of the Adeptus Custodes' unique war machines is an expression of the height of the Imperium's technological capacities. Many can be described as paragon variants of well-established Imperial patterns such as the Arachnus Blaze Cannon, which were recognisably developments of widely used Imperial las technology, but built with esoteric and powerful components which could never be replicated en masse. Others, such as the Iliastus Accelerator Cannon, were however at the cutting edge of new military developments, incorporating technologies gleaned and tested on the frontline of the Great Crusade.

Relics of Terra
"Whatever the weapons we wield, whatever the deeds we perform, they are justified. Without us, the Golden Throne would fall, and without the Emperor to guide them, Humanity would follow."

- Ganestus Talorn, Allarus Custodian

During the Great Crusade, the Custodians hoarded some of the most powerful and esoteric weapons technology ever encountered by the Imperium. Though much of it was expended during the Horus Heresy, some of these ancient artefacts still exist, locked away in vaults deep beneath the Imperial Palace, waiting to be borne to war when the need is greatest:


 * Gatekeeper - Gatekeeper is an ancient, master-crafted Guardian Spear. This potent weapon thrums with barely contained power. Its machine spirits are capable of near-prescient predictive targeting, allowing the wielder to mow down the enemy before they can come within blade's reach.
 * Raiment of Sorrows - Handwoven by the sisters of the Order of Lamentations and allowed to sit in state at the foot of the Golden Throne for a full century, this shroud-like raiment is a potent reminder of the Custodians' one great defeat. Its presence fills them with a cold determination to never fail again.
 * Eagle's Eye - This magnificent helm incorporates sensorium-gheists, trapped within micro-reliquaries and compelled to shriek their technomantic warnings to the wearer whenever danger threatens.
 * Auric Aquilas - Incorporating forbidden secrets of ancient archeotech from the Dark Age of Technology, Auric Aquilas is a truly magnificent gravitic jetbike. Swift as thought and protected by a shimmering golden force field, it bears its rider swiftly and safely into battle.
 * The Praetorian Plate - This suit of Allarus Terminator Armour - itself a hand-crafted relic of great antiquity - has been adapted to incorporate a still more ancient empyric beacon and archeotech teleport-shunter that allows its wearer to leap directly through the warp to the aid of those he is sworn to defend.
 * The Veiled Blade - An ancient blade that burns with a bitterly cold and dark energy, the Veiled Blade is bestowed upon a Custodian who has vowed to recover that which should remain hidden from Humanity and return it to the Dark Cells.
 * Emperor's Light - Said to have been crafted from a crystallised shard of the Emperor's glorious light, this masterwork Misericordia has been borne into battle by three separate Captain-Generals. It is said to flood the heart of its victim with holy radiance, and is an object of dread to traitors and heretics alike.
 * Wrath Angelis - This ancient and expertly crafted vexilla was created for the battle against the Orks upon the world of Ullanor. During that conflict, pinpoint fire support was key to victory. Thus, this vexilla incorporates a multi-spectral targeting shrine that links to warships in orbit and guides in trans-atmospheric strikes with remarkable accuracy.
 * Auric Shackles - These fetters were forged in the Dark Age of Technology, and adapt themselves to shut down the neural nets of any sentient beings, rendering even the thought of escape impossible. They are used to capture the Imperium's most dangerous foes.
 * Obliteratum - This dread vambrace weapon incorporates several forbidden technologies whose possession would be death to any beyond the Adeptus Custodes. It fires concentrated antimatter, compressed within splinterglass canisters that shatter upon impact. Victims are annihilated on a molecular level by the night-black blasts caused by this weapon's fire, vanishing in terrifying eruptions of nothingness.
 * Fulminaris Aggressor - This vexilla was fashioned after the fall of Goge Vandire to honour the wrath of the Emperor in punishing traitors and tyrants. Its micro-thundercoil generatorum crackles with barely restrained power that arcs out to annihilate nearby foes.
 * The Castellan's Mask - This finely worked pauldron is awarded to whichever living Custodian currently holds the greatest tally of victories in the Blood Games. It is rare, of course, that even the resourceful warriors of the Adeptus Custodes succeed in these endeavours, and so to honour one who has done so more times than any other is only right. He who bears the Castellan's Mark is guaranteed to be a superlative strategic genius, an expert in spotting and exploiting weaknesses with merciless efficiency.
 * Faith Absolute - This ominous vexilla was created for the infamous Witching Wars. It is able to discharge a pulse of disruptive contra-empyric energies that can unmake an onrushing psychic manifestation in a heartbeat.

Vehicles

 * Coronus Grav-Carrier - Perhaps one of the most well-known of the vehicles used exclusively by the Adeptus Custodes, this transport was already widely utilised across the Legio Custodes in the closing decades of the Great Crusade, replacing the limited numbers of the relic Jocasta Pattern Grav-Craft that had survived the Unification Wars on Ancient Terra. The use of heavily protected grav-craft by the Legio Custodes granted their force a degree of speed and agility that could not be matched by the grinding armour of other forces of the Imperium, allowing them to deploy, redeploy and evade without the danger of being easily pinned down by enemy troops or hazardous terrain. The Coronus Pattern also served as the inspiration and technological basis for the Pallas and the Caladius grav-craft, developed to meet the specific strategic needs of rapid attack and line of battle tank, respectively.
 * Caladius Grav-Tank - Based upon the technology of the Coronus, the smaller Caladius grav-tank was designed to utilise the firepower afforded by the heaviest elements of the Legio Custodes' arsenal on a highly-mobile, protected platform. Given the fusion of advanced systems and weapons, the Caldius was perhaps the most powerful battleline armoured unit of its size in the Imperium's forces, utilising technologies and materials derived not only from the Dark Age of Technology, but from developments made as a result of the Great Crusade's two centuries of warfare. The principal armament of the Caladius was a double-barrelled Accelerator Cannon, an advanced weapon which became a precursor to the more mass-produced cannon retro-developed into the armament of the Legiones Astartes Sicaran Battle Tank, which fulfilled a similar role to the Caladius as a high-speed armour destroyer. A less common variant was the "Caladius-Annihilator" which featured an enhanced capacitor-fed Arachnus Blaze Cannon that is potent enough to pose a threat even to super-heavy armoured vehicles.
 * Dawneagle Pattern Jetbike - These mounts are utilised exclusively by the airborne warriors known as Vertus Praetors. The Dawneagle jetbike is an incredible vehicle, a crusade-era relic wrought in auramite and adamantium. These bikes are almost as large as light fighter craft and - while they are still grav-skimmers - can deliver a near supersonic turn of speed. Their hulls are phenomenally durable, allowing their riders to slam through walls and enemy warriors without being unseated, and they react pugnaciously to the slightest touch of the controls, able to jink effortlessly through incoming fire. When armed with Hurricane Bolters, the Dawneagle can plough bloody furrows through enemy hordes. However, it is when equipped with salvo launchers that Vertus Praetors truly come into their own as lightning-fast tank hunters. They scream across the battlefield, rapidly outflanking and encircling the heaviest enemy vehicles before annihilating them with strafing runs of melta missiles. Even enemy aircraft are not safe, for by combining their fire the Vertus Praetors are able to weave airborne webs of flakk blasts into which hurtling enemy aircraft slam with terminal results.
 * Gyrfalcon Pattern Jetbike - One of a number of customised Jetbike designs utilised by the Legio Custodes Agamatus Jetbike Squadrons, the heavy duty, plasma motor-boosted Gyrfalcon Pattern Jetbike served as the Custodians' steeds in battle. The increased power of the design supported not only the heavily armoured Custodian Guard, but also allowed it to mount a powerful Iliastus Pattern Bolt Cannon as its on-board armament. The Gyrfalcon was more powerful even than the Scimitar Pattern Jetbike associated with the Legiones Astartes, a heavy-design more akin to an armoured one-man speeder than a true Jetbike. In addition, it augmented its grav-repellor systems with a plasma-thrust motor for huge temporary bursts of speed. The Agamatus Squadrons of the Legio Custodes exploited these war machines to operate as both a rapid response and suppression unit in the field.
 * Pallas Grav-Attack - Designed, it is reported, to incorporate advanced manoeuvring and autonomous response systems recovered by the great Techno-archaeologist Arkhan Land, the Pallas Pattern grav-attack was one of the most recent designs entering service with the Legio Custodes prior to the Burning of Prospero. Clearly based upon the lineage of the Coronus and Caladius grav-vehicles, it was smaller than either, a single-seat high-speed attack skimmer analogous in role to the Land Speeder more commonly employed by the Legiones Astartes. Designed as a high-manoeuvrability hunter-killer, the Pallas Pattern grav-attack squadrons provided the Legio Custodes with a greater rapid strike capacity than could be afforded by the use of ground troops alone. In this it replaced standard pattern skimmers as well as larger war machines such as the ancient Jocasta Pattern grav-attacks, themselves relics of the Unification Wars, and considerably smaller Hermes Pattern grav-sleds, which while highly agile and swift, offered little in the way of combat survivability.
 * Orion Assault Dropship - Created as a dedicated super-heavy assault dropship for the Legio Custodes, the Enyalas Pattern Orion can carry a full task force of the Emperor's Talons into combat. Protected by frontal armour superior to that of the Legiones Astartes Thunderhawk gunship, its Arachnus Heavy Blaze Cannon and Heavy Bolters can swiftly clear a landing zone of hostile infantry and armour with brutal efficiency, allowing the units within to deploy before it soars back into the sky to unleash death upon any foe who dares approach.

Dreadnoughts

 * Contemptor-Achillus Dreadnought - In those isolated cases where the body has been all but irrevocably destroyed but the Custodian's mind remains intact and their will to survive undimmed, internment within the cold and unyielding body of a cybernetic Dreadnought is the next step. To this purpose, the few Dreadnoughts of the Legio Custodes were as singularly advanced as their other wargear, outfitted with weapons and systems artificer-made by the servants of the Imperial Court. At the time of the outbreak of the Horus Heresy, the most widely employed was the Contemptor-Achillus, a general battle unit which combined phenomenal strength and speed with the echoes of the interned Custodes' own unmatched martial skill. In battle, the Contemptor-Achillus often utilised a deadly Achillus Dreadspear for close combat. These were scaled-up versions of the iconic Guardian Spear of their Legio that possessed devastating power. For fighting at range, they also often utilised a pair of wrist-mounted Storm Bolters, Infernus Incinerators or Adrathic Destructors.
 * Contemptor-Galatus Dreadnought - A sub-variant of the Contemptor-Achillus, the Contemptor-Galatus was designed to provide a mobile anchor point for a Legio Custodes battleline in the field. To this end, the Galatus was analogous to the specialised Sentinel Guard formations of the Legio Custodes, and was armed with a potent combination of a huge Galatus Warblade and vastly enlarged version of the Praesidium Shield. The warblade allowed the Contemptor-Galatus to swiftly and efficiently reap a murderous toll of any massed infantry assault at close quarters, or indeed hack through armoured vehicles and monstrous xenos with equal ease. It was the defensive power of the hulking Praesidium Shield, however, that was the Contemptor-Galatus' most significant feature, as with it the already durable Contemptor chassis became nigh on impregnable, even against the heaviest of heavy firepower.
 * Telemon Heavy Dreadnought - Fewer than a handful of Telemon Dreadnoughts were to be found within the ranks of the Legio Custodes, each intended to stand sentinel over its charges no matter the force brought against it. In part this rarity was due to the cost in labour and resources for the creation of such a superlative engine of war, for each bore at least one plate worked by the Emperor's own hand, and also the rarity of appropriate candidates to control them. The honour of interment in one of the few existing Telemon sarcophagi was awarded only to the most celebrated warriors within the sodalities of the Legio Custodes, and until a worthy candidate found his end in battle, the Dreadnoughts stood silent and empty. Despite this, the sheer power of an unleashed Telemon class Dreadnought far outweighed the trials of its construction, for few could stand against the array of esoteric, hand-crafted weapons that graced its chassis or the ferocious will and warrior skill of the master Custodian interred within.
 * Venerable Contemptor Dreadnought - Each Venerable Contemptor Dreadnought is an ancient war engine, a relic that incorporates wonders of technology that the Imperium can no longer replicate. Its auramite armour plates are expertly crafted and maintained. Its limbs are articulated by fibre-bundles and servo-motors that afford it immense strength. Its weapons are perfectly calibrated, while its hull is sheathed in the crackling energies of an atomantic shield that can dispel laser blasts and artillery shells amidst bright flares of energy. Auto-repair protocols allow the Dreadnought to shrug off crippling battle damage, while motive shrines and auto-sanctified backup systems stand ready to take the strain should the Contemptor undergo serious combat trauma. Yet for all this arcane technology, the most important component of the Venerable Contemptor Dreadnought is the living warrior interred in the sarcophagus at its heart. When faced with certain death, a Custodian may choose to be preserved within a Venerable Contemptor Dreadnought so that he can continue to fight for the Emperor. There should be no mistaking that this is the act of a martyr, for life within a Dreadnought sarcophagus - even one as advanced as the Venerable Contemptor - is a twilight existence at best. The pilot is shorn of all unnecessary flesh, rendered down to little more than a sack of organs and brain matter sustained within an armaglass amniotic tank. The Custodian becomes a god of war, able to stride unharmed through hails of fire and crush the Master of Mankind's foes with their hydraulic might. In return, they face an eternity cut off from the outside world, bound to mechanical systems that can never truly replicate the feel of sunlight upon their skin, or the satisfying crunch of their blade through an enemy's flesh. Despite this, there are tales of unharmed Custodians volunteering to pilot Contemptors whose previous occupants were slain in battle. Those soon to depart as Eyes of the Emperor, those who feel they have dishonoured themselves, even warriors who simply will not turn aside from what they perceive as their duty; all, it is said, have given their flesh willingly so that the Contemptor Dreadnoughts of the Custodes continue to stride to war.

Trivia
The names of the five castes of the Adeptus Custodes that distinguishes their various combat roles come from ancient Terran history:
 * Hykanatoi - The name of the Hykanatoi (from Greek: Ἱκανάτοι, "the Able Ones") sometimes Latinised as Hicanti, were one of the Byzantine tagmata, elite guard units based near the Eastern Roman Empire's capital of Constantinople. Founded in the early 9th Century, the Hykanatoi survived until the late 11th Century.
 * Tharanatoi - The name Tharanatoi was likely derived from two sources. The first is Celtic mythology, which references Taranis, the god of thunder and Thanatos (from the Greek: Θάνατος "Death") who was the personification of death in Greek mythology.
 * Kataphraktoi - The name of the Kataphraktoi was most likely derived from the word "cataphract", a form of heavy armoured cavalry used in ancient warfare by a number of peoples in Europe, East Asia and the Middle East. The English word is derived from the original Greek (κατάφρακτος Kataphraktos (plural: κατάφρακτοι Kataphraktoi), literally meaning "armoured" or "completely enclosed". An entirely appropriate name for Jetbike-mounted Custodians.
 * Ephoroi - Ephoroi is a derivative of the ancient Greek "ephor". The ephors were leaders of ancient Sparta and shared power with the two Spartan kings. The word "ephors" (Greek ἔφοροι éphoroi, plural form of ἔφορος éphoros) comes from the Greek ἐπί epi, "on" or "over", and ὁράω horaō, "to see", i.e. "one who oversees" or "overseer".
 * Moritoi - The name Moritoi comes from the ancient Latin word mortis, "death". An appropriate name for those Custodians who have suffered injuries so terrible that they cannot go on living without being interred within the cybernetic life support sarcophagus of a Dreadnought to sustain their biological functions.
