"If a man dedicates his life to good deeds and the welfare of others, he will die unthanked and unremembered. If he exercises his genius bringing misery and death to billions, his name will echo down through the millennia for a hundred lifetimes. Infamy is always more preferable to ignominy."
— Fabius Bile, The Clone Lord at the Desecration of Kanzuz IX
Fabius Bile Clonelord

Fabius Bile, the Clonelord

Fabius Bile is a Chaos Space Marine Apothecary, originally of the Emperor's Children Traitor Legion, who has repeatedly attempted to use his knowledge of cloning and genetic engineering to create superhuman beings under his control in a quest to match and then exceed the Emperor of Mankind's original scientific achievement in creating the Primarchs and the transhuman Adeptus Astartes.

Travelling the galaxy more widely than any other Chaos Lord of the Traitor Legions, Bile has earned a number of epithets and aliases from those who have suffered the affects of his vile experiments. On Dimmamar, Bile was known as the "Chem-master", for there he changed the atomic composition of the air until the population was forced to ingest his transformative serums or slowly suffocate. On Arden IX and in the Bray System he is "Manflayer", for there he would wear the skins of those who opposed him as a great stitched cloak, forcing the skinless survivors to carry the garment behind him like a bridal train.

To the wretched tribes living among the ravaged hives of Paramar V he is the "Clonelord", for he vat-grew obedient twins of every firstborn child and replaced them with their doppelgangers the better to guide the planet's descent into darkness.

To Bile himself, there is only one title that does his magnificence justice -- the "Primogenitor". He believes that in him is the Emperor's boundless artistry reborn. He claims he has unlocked the secrets of the Emperor's earliest replicae experiments during the creation of the Primarchs and the first Space Marines. Bile's twisted alchemical knowledge and skills at genetic manipulation can be attested to by every planet he has had contact with, for he has left a trail of foul deviants and twisted abominations wherever his ships have landed.

His name has become a curse to the High Lords of Terra and those of the Apothecarion who have learned of his legend. Many believe that he has irrevocably tainted Mankind's gene pool, polluting it with hidden growth strains and lurking corruptions. Some scattered Chaos Cults even worship him as Pater Mutatis, father of all the mutants that skulk in the underbelly of the Imperium. It is a belief that Bile does nothing to dissuade.

Fabius Bile is accursed throughout the galaxy and a Renegade even from his own Legion. Formerly of the Emperor's Children, Bile's fascination was always with the mysteries of life, not death. Amidst the carnage of the Horus Heresy, Bile aided the Emperor's Children in their inexorable journey into the embrace of Slaanesh. He altered their brain chemistry to sharpen their senses and connected their pleasure centres more directly to their nervous systems so that every stimulus would bring them unholy joy.

Bile left Terra before Horus' defeat, accompanied by a retinue of altered followers. He moved through the war-torn Imperium like a shard of glass through an intestinal tract, selling his services to rebel commanders for prisoners, genetic samples and ancient technologies. Many ambitious overlords came to rue the day they let Bile experiment on their armies, until his acts of genocide and other atrocities sickened even the most deranged maniacs. He eventually found his way to the Eye of Terror, where he offered his services to the highest bidders, promising the Champions of Chaos vile cures for their problems. There he set up a new base of operations upon a Crone World. Once, it had been home to the best and brightest of the Aeldari civilisation; now it was a darkened, twisted place of crawling madness.

Most of Bile's experiments end with his subjects dead or so horribly deformed they might wish for death. Yet the altered specimens of Bile's efforts exhibit strength many times greater than the human norm. These are Bile's proudest creations, the New Man that forms the pinnacle of his foul art.

The shattered Traitor Legions making their home in the Eye of Terror have particular need of Fabius Bile's skills. His augmented warriors and bio-magicks can give a warband of Heretic Astartes a vital edge, and cloned warriors and slaves are put to good use on a hundred battlefields. Yet it was the skills Bile once learned as an Apothecary of the Emperor's Children that are most precious to the lords of Chaos. The Traitor Legions still need the ability to extract the Progenoid Glands of the fallen in order to create new Chaos Space Marines, and in this strange art Bile is undoubtedly preeminent.

Without such skills, the Long War would slowly grind to a halt, and the fires that Horus had lit would go out forever. With so much influence at his behest, Fabius Bile has negotiated cunning if fragile bargains with the Daemon Primarchs, selling his secrets to each of them but refusing to aid one more than any other. In this way the Primogenitor ensures his position at the heart of a web of influence that spans across the Eye of Terror and beyond. Since the birth of the Great Rift, he has used his leverage to a singular end -- the capture of the Primaris Space Marines sighted across the galaxy. His fondest desire is to harvest the genetic bounty of Primarch Roboute Guilliman himself.

Due to the original infection of the III Legion's gene-seed by the virus known as "the Blight" which still affects him, Bile's gene-seed organs soon sprout tumors that result in his rapid physical decay and death. He has managed to sustain his life over the long centuries by creating clones of himself and transferring his own brain into them, one after another for millennia.



Captain Fabius2

Apothecary Fabius Bile of the Emperor's Children Legion during the Great Crusade

Fabius Bile was born to a minor noble house from the mountains of northern Europa on Terra during the Unification Wars era of the 30th Millennium. His birthplace was the city of Ingolstadt, but Fabius remembered little of his childhood following his later transformation into an Astartes save for the sound of music and a library with real, leather-bound books. He earned the honour as an adolescent of being inducted into the IIIrd Legion of Space Marines and was one of the 200 surviving Terran Battle-Brothers of that Legion who travelled to the world of Chemos with the Emperor when the Master of Mankind rediscovered His lost Primarch son Fulgrim. Fabius later served as an Apothecary of the Emperor's Children Legion during the Great Crusade, and was ultimately corrupted by Chaos in his desire to enhance the physical perfection of the Emperor's Children Astartes.

In the latter years of the Great Crusade, Bile's uncanny skills saw him move from the rank of simple Apothecary all the way to earning the grade of a Lieutenant Commander of the Emperor's Children. But even as a leader of Astartes, Fabius was rarely away from his surgeries for long. Bile saw his fellow warriors not as comrades or brothers, but as fresh test specimens ready to be experimented upon. Each was but a stepping stone in his great work; a tapestry of genetic information to be unpicked and woven anew in Bile's quest to understand the forbidden sciences of the Emperor Himself.

Using the knowledge of genetic engineering he had gained from the corpses of the Slaanesh-worshiping reptilian Laer xenos of the world of Laeran that had been conquered by the Emperor's Children during the Great Crusade, Bile developed a series of modified gene-seed organs. These organs were eventually implanted into all of those members of the IIIrd Legion who joined their Primarch Fulgrim in turning against the Emperor. This lead to the creation of the first Noise Marines, as well as other types of variant mutantChaos Space Marines. At the start of the Horus Heresy before the Drop Site Massacre of Istvaan V, Bile modified the nervous systems of his fellow Emperor's Children so that all sensations of pain were rewired to stimulate the brain's pleasure centers instead. This meant that even the infliction of truly horrific or even mortal wounds produced unrivaled pleasure in the modified Astartes.

The Blight

Apothecary Fabius

Being inducted into the IIIrd Legion, known to some as "His Heralds," prior to the discovery of their Primarch Fulgrim, Fabius hailed from northern Europa on Terra and was a purple-eyed, golden-haired Legion Apothecary, wearing the thunderbolt and rayed sun insignia of the Legion proudly on his purple plate. Whilst under the stewardship of Legion Master Thrallas, the Legion found itself threatened with extinction.

The attack of the Selenar Gene-Cults on a vast portion of their gene-seed and a viral infestation of the rest of the stored material in combination with combat attrition had left the III Legion perilously close to being unable to replenish its ranks. To counter the loss of Astartes, gene-seed implantation was sped up and new recruits were rushed to the frontlines. Whether they continued to carry the viral infestation or not, was unknown.

Amongst these new recruits was Fabius. As an Apothecary, it fell to Fabius to collect the genetic material of the fallen and ensure the new generations of Astartes, however the Blight, as it came to be known, ruined that material. Yet nobody knew how to detect the viral infection, let alone cure it. Thus Fabius began his research, looking to rid his Legion of that infestation that unleashed tumors in their gene-seed organs and ultimately destroyed them.

Since the Emperor's Children, as they were renamed after the Proximian Betrayal, had always looked to perfection, they worked tirelessly to better themselves. It is no wonder that Fabius, after working on the corpses of many of his Legion brothers, found a way to test for the Blight. True to their ideals, every infected brother Astartes was executed. Hardened by such decisions, Fabius continued his research and mapped the genetic make-up of the whole III Legion in search of a cure for the Blight.

When he added his own samples to that endeavour, he discovered that he too had been infected by the virus. This could not be allowed for he was too important to die, his research too important to end with his execution for imperfection. Thus he switched the samples and had one of his fellow Battle-Brothers killed in his stead. Bending all his efforts to finding a cure, he performed more experiments and secretly took genetic material from his dead brothers to prolong his existence.

When the III Legion finally found their Primarch on Chemos, Fabius hoped for a cure for himself. That was not to be. The Emperor's Children Legion was saved instead with the infusion of a new and pure source of their gene-stock extracted from Fulgrim that created new gene-seed. Fabius, however, could not be saved in this way, for the gene-seed causing his tumors could not be reengineered and then reimplanted. It could only be cloned, and the Blight always reasserted itself in time.

Fabius kept himself alive by mechanical and scientific means, always trying to find a cure. When the daemon possessed Fulgrim during the Drop Site Massacre at Istvaan V, he estimated that he had about one Terran year of life left to him. It was at that time he finally resolved to go to his Primarch and confess all that he had done. Where science had failed, he had turned to the arcane to prolong his life. For was he not worthy? Had he not helped his brother Astartes attain perfection?

Horus Heresy

Fabius Bile's Enhanced Warriors

Fabius Biles' enhanced warriors during the Horus Heresy

During the Horus Heresy, Bile did not follow the path of his fellow Battle-Brothers in their worship of Slaanesh. Instead he distanced himself from his Legion and devoted himself to researching forbidden genetic engineering technology that would unlock the secrets behind the Emperor's creation of the Primarchs and the Astartes.

Following the Drop Site Massacre Fabius had explored the ancient choral conclaves on Istvaan V, scavenging knowledge left there by the Chaos-corrupted Warsingers of the Isstvan System.

Fabius later joined several Emperor's Children commanders such as Lucius and Marius Vairosean in using extreme torture to exorcise the daemon that had possessed Fulgrim in the wake of the Drop Site Massacre.

At his Primarch's demand, Fabius produced his first cloned Primarch, creating a replica of Ferrus Manus, the Primarch of the Iron Hands Legion and Fulgrim's greatest friend among his brothers, which Fulgrim tried to again convert to his cause. Every time the clone of Ferrus refused and Fulgrim killed him again. Fabius created multiple clones of Ferrus, and each refused to join the Traitors' cause before Fulgrim slew him in a rage.

Fabius proved vital for the Emperor's Children during the Heresy, reviving both Lord Commander Eidolon and Lucius at the demand of their Primarch. As the war ground on, his experiments became more and more depraved, torturing captive Space Marines of both the Traitor and Loyalist Legions to give birth to his first generation of Terata, enhanced warriors who could prove physically stronger than even other Astartes but were prone to rampant mutation and mental instability.

The events of the Heresy culminated in the Siege of the Emperor's Palace. The Emperor's Children, by this time a Traitor Legion fully under the sway of the Renegade Warmaster Horus, invaded Terra with Horus but took little direct part in the fighting around the palace.

Instead, they descended upon the civilian populations of Terra's Administratum; the mind-bogglingly complex infrastructure of clerks, bureaucrats, curators and menials whose efforts kept the lifeblood of the Imperium flowing. Whole dynasties of staid scribes and strata of haughty prefects were caught as they fled the war zone consuming their world. They were consumed in their turn. More than a million prisoners were rendered down under Bile's supervision and distilled into an array of stimulants and intoxicants for the Emperor's Children to ingest. It was the crowning depravity of their slide into the abyss, and it pleased their master Slaanesh greatly.

Perhaps it was at this time that Fabius Bile committed himself completely to the darkness. He was certainly foremost in the experimentation upon living prisoners, keeping them alive in their torment for weeks at a time and cataloguing every ghoulish result. Even amidst the carnage that followed the breaking of the Heresy, his fascination was with life, not death. Bile guided the Emperor's Children ever further into the embrace of Slaanesh, the Dark Prince. His surgeries ensured that only one path was left to them; an eternal pursuit of sensual excess that has scarred the stars ever since. Yet Bile himself never underwent the surgeries he so thoroughly inflicted on his so-called brothers.

After the Heresy

As his fellow Space Marines lost themselves in sensuality, Bile moved further and further along his own dark path. He left Holy Terra shortly before Horus' defeat at the hands of the Emperor, accompanied by a handful of his most gifted acolytes. This act incensed Fulgrim, who put a bounty on his former Apothecary's head. Bile's warband moved through the war-torn Imperium like a shard of glass in an intestinal tract, carving a new legend with every twist and turn of their journey. Wherever he made planetfall, the Primogenetor offered his assistance in exchange for prisoners, genetic samples and ancient technical libra. Despite his infamy, Bile still adhered to a twisted version of the old Imperial Truth, believing that only the foolish and weak sought the comfort of gods like the Ruinous Powers and the pursuit of scientific truth was to be held above all other values.

Many ambitious planetary overlords came to rue the day they joined their fates with Fabius Bile. His atrocities and acts of mass genocide often repelled even those that had ordered the deaths in the first place. Nonetheless, few could deny that the assistance Bile offered was potent. His serums could transform mediocre defence troopers into ravening super-soldiers, and his mastery of the cloning process saw him able to mobilise thousands of "perfect warriors" within months. As a consequence, genocide and genetic debasement marked his path and the Inquisition still strives to eliminate the threat of his genetically enhanced, psychotic, "New Men" from star systems across the Imperium.

Yet for all his twisted genius, Bile could not hold back the furious crusade of Loyalists that launched outward from ravaged Terra during the what became known as The Scouring. Retribution finally caught him in the Arden System, where he was supporting the excesses of the Renegade Lord Tyrell in exchange for foetal material. The Salamanders Chapter launched themselves down upon the corrupted world of Arden IX like fiery angels of vengeance. Bile's flesh refineries and cloning vats all burned in a single night as the righteous fury of the Salamanders incinerated all evidence of the Primogenitor's precious experiments.

Bile brought low a dozen Space Marines in the battle, his rictus grin illuminated by flickering fire as his once-brothers died agonising and inventive deaths. Yet he barely escaped the battle. He was forced to flee for his life, and his ship was crippled by an Imperial Gothic-class Cruiser as he fled for the dubious refuge of the Warp.

Whether by accident or design, Bile's vessel was slowly drawn into the Eye of Terror. He drifted there for an age, constantly experimenting on those few acolytes he had left until the hand of some dark god guided his ship into the gravity well of a Daemon World. Once, the planet had been one of the scintillating jewel-worlds of the Aeldari Empire before their own debaucheries saw their civilisation torn apart. Now it was a shrivelled ruin, a Crone World of seething madness called Urum that echoed to the screams of souls long dead. To Fabius Bile, it became home.

Cloning Horus

Bile soon discovered that the shattered Traitor Legions making their home in the Eye of Terror in the 32nd Millennium had particular need of his skills. His augmented warriors and bio-magicks were useful indeed, and clones and slaves were put to good use on a hundred battlefields. Yet it was the skills Bile had learned as an Apothecary that were most precious to the Traitor Legions. Most of all, they needed Bile's ability to extract precious progenoid glands from the fallen in order to create new Chaos Space Marines.

Without these skills, the Long War would slowly dwindle, and the fires that Horus had lit would go out forever. With so much influence at his behest, Fabius Bile negotiated a delicate bargain with the Traitor Legions, selling his secrets to each of them but refusing to aid one any more than any other. In this way, the Primogenitor ensures his position at the heart of a genetic web that spans across the Eye of Terror and beyond.

Bile took up command of the remaining Emperor's Children and regrouped at at Canticle City, the fortress of the Emperor's Children on the Daemon World of Harmony. Bile went about continuing his work from before the Heresy, attempting to unravel the secrets of the gene-seed and the Emperor's techniques in creating the Primarchs. To that end, Bile continued to clone Primarchs as he once had Ferrus Manus.

At some point after the Heresy, the Primarch Horus' body was stolen from the Sons of Horus' Legion world of Maleum, for with its potent genetic information and biological secrets, it was a great prize indeed. In a sudden assault, the remnants of the debased Emperor's Children, having grown vastly in power after firmly cementing their terrible pacts with Slaanesh, easily smashed their way through the defences of the Daemon World of Maeleum and into the central chambers of the Sons of Horus' stronghold. They stole the body of the slain Primarch from the heart of its tomb and spirited it away, handing it over to the Primogenitor.

Bile cloned Horus, much to the Sons of Horus' disgust. Bile thought that this would, amongst other things, curry the favour of Abaddon the Despoiler. Instead, Abaddon destroyed the Horus replicae during the Battle of Harmony, proclaiming it a "blasphemy" (as well as a potential threat to his own control over the Forces of Chaos as Horus' heir), and ordered his newly renamed Black Legion to raze Bile's Laboratoria on Harmony and destroy his experiments.

The other Emperor's Children considered Bile's retreat from Canticle City with the remnants of his work as a betrayal. After the fall of Canticle City and Harmony, Bile found himself pursued by multiple foes, including his fellow Traitor Marines, the Craftworld Aeldari, the Dark Council, and even Fulgrim himself. He eventually returned to the Crone World of Urum.

After these events Bile essentially left behind the cause of the Traitor Legions and became a "free agent", pursuing his own agenda. He has also successfully managed to clone himself, with several of his replicaes active in various places, as he is said to have secret facilities in a dozen locations across the Milky Way Galaxy. His arrogance and twisted amoral intelligence is more than matched by his sadistic cruelty.

The Shattering

Bile eventually ended up leading a group of affiliated Apothecaries from various Legions known as "the Consortium" based on his new home of Urum. Looking for a way to stop the continuous decay of his body and achieve immortality, Bile was a participant in the Shattering, the attack by the Emperor's Children on the Aeldari Craftworld of Lugganath in 764.M34.

During the attack it became apparent that his former acolyte Oleander Koh and a group of Harlequins had engineered the events to try and convince Bile to lead the Emperor's Children once more. However Fabius refused to become a military leader and instead insisted that only his scientific work would continue.

The Thirteen Scars

It is rumoured amongst the acolytes of Bile that the Primogenitor studied the arts of pain under the Haemonculi of Commorragh. These maestros of torture were so skilled in their works that even Bile, with several thousand Terran years of experience in wielding the scalpel, was a mere novice by comparison.

Nonetheless, after his eventual capture in 796.M37 in a raid on an Emperor's Children citadel, Bile so impressed the Coven of the Thirteen Scars with his improvisational tortures that he was allowed to visit the inverted spires of their city-dungeons as a guest instead of a victim. There, he aided the Thirteen Scars in the creation of the Tower of Flesh; a living, breathing fortress made from the remains of those that had wronged the Coven in their lives.

Without Bile's elixirs and the runes he carved into the fleshy walls of the mobile fortress known as the "Tower of Flesh," the sentient tower may not have lived more than a few solar days, but it lives on still, dangling from the underside of Commorragh like a fleshy stalactite. Within its blood-dripping walls, Bile was taught many of the Haemonculi's lesser secrets. In the dark circles of the truly evil, the magnitude of such a feat is whispered in hushed tones. No greater honour have the Drukhari bestowed upon a member of the lesser races in all of human history. Bile realises this fact well, and has put the lessons he learned there to good use ever since.

This knowledge eventually led to him tutoring his fellow Emperor's Children in these dark arts, which led to Bile coming into conflict with the Thirteen Scars at the Battle of Belial IV in 993.M37. The Coven slaughtered those who Bile tutored, and surgically altered his brain to ensure that Fabius himself could never speak of what he had learned.

The New Men

Fabius Bile & Retinue

Fabius Bile with a retinue of his "New Men" - enhanced Chaos Space Marines retinue

The Chapters of the Adeptus Astartes are well aware of Fabius Bile's nightmarish actions. In every Segmentum, the populations of once-productive Imperial worlds have had to be wiped out wholesale. Once the infections of Bile's black arts have taken hold, the mewling victims must be purged by fire and sword to prevent them fleeing. Only by personal investigation can it be ascertained just how many citizens have fallen to Bile's genetic afflictions. Mostly, the Chapters charged with investigating such worlds find once-civilised planets populated by ragged hordes of debased, shambolic monsters. Not all of these purgation missions are mercy killings.

Upon dozens, perhaps hundreds of worlds, the Space Marines have encountered fierce resistance from hardened cadres of enhanced humans who fight with the strength and cunning of devils. These altered half-spawn exhibit strength, speed and intelligence many times higher than the human norm and are depraved, psychotic killers to a man. They are Bile's proudest creations, the New Men he would spread throughout the galaxy. Fickle, selfish, obsessive, aggressive, murderous; they echo their creator in more than just their physique. Each of man's worst traits has been brought to the fore and magnified tenfold, married with the psychology of a tyrant and the strength of a madman. Even the Inquisition do not know how many of these abominations have escaped into the galaxy. Many of them are altered subtly, their corded muscles and crazed minds hidden in plain view until their incipient psychosis sends them on a manic killing spree.

Bile on Baal

"Why struggle? You'll feel so much better once I'm finished."
— Fabius Bile

Teetering on the brink of oblivion following the near-disastrous Blood Angels Chapter civil war on the Shrine World of Sabien, the fate of the Blood Angels Chapter required the magnanimity of their Successor Chapters. Lord Commander Dante summoned all of the Blood Angels' Successor Chapters for a conclave on Baal. Dante called on the Blood Angels' Successors to aid the Chapter in the protection of their common Primarch's homeworld and his remains from the attack of both the Tyranids and the Forces of Chaos.

While Dante led the discussion at the conclave, the Apothecaria was working on a radical new procedure to replenish the ranks of the Blood Angels in one swift stroke: the lost art of replicae (cloning). Caecus was the Chief Apothecary or Apothecae Majoris of the Blood Angels. Disturbed by the dwindling numbers of his Chapter, and dreading its extinction, he was involved in fruitless experiments, which Lord Commander Dante ordered stopped, to clone Space Marines, thus eliminating the need to go through the arduous process of the maturation and implantation of the gene-seed in an Aspirant. However, Caecus disobeyed the order and secretly continued the experiments, prodded by an agent of Fabius Bile.

He was tricked into bringing Bile, who was disguised as a well-known Adeptus Mechanicus Magos Biologis, Haran Serpens, to Baal, mistakenly thinking the false "Magos" would help in cloning Space Marines to increase the Blood Angels' numbers. Through Bile's manipulations, Caecus was duped, and only managed to create monstrous, mutant clone-Astartes known as "Bloodfiends" who were consumed by the Red Thirst. These creatures were a shattered mirror reformed in the image of a Blood Angel, but lacked any of the qualities that might be thought of as human. The mutations that cursed the gene-seed of the Blood Angels had been enhanced by the machinations and Chaotic tech-heresy of Fabius Bile, and with each drop of blood they consumed, the thirst that dominated the Bloodfiends grew stronger. The mutants broke free from the confines of Caecus' laboratorium and began to run rampant through the sacred halls of the fortress-monastery of the Blood Angels. During their rampage, Bile managed to steal a glass vial that Caecus had carried back from the Chapel of the Red Grail -- a measure of the mingled blood of a hundred centuries of Sanguinary Priests and the Primarch, the raw vitae of the Chapter.

During the Bloodfiends' rampage, a small group of the bloodthirsty mutants assaulted the sacred Chapel of the Chapter's fortress-monastery. Brother Corbulo raced to the Chapel to confront the creatures. He knew exactly what it was the beasts wanted, and he bellowed out a denial, charging in a headlong rush to meet such embodiments of corruption. The creatures swarmed Corbulo as the Sanguinary Priest carved into them with his Chainsword Heaven's Teeth. But the largest of the Bloodfiends, a massive brute easily the size of an Astartes in Terminator Armour, threw itself towards its target -- the Red Grail and the precious blood of the Primarch it contained. The Bloodfiend seized the holy relic and then tipped the contents of the cup into its open mouth and drained it to the dregs. Now that the beasts had tasted the blood of the Primarch, they only craved more. In the aftermath of this desecration, Bile had achieved his goal and escaped from the Blood Angels' homeworld with a sample of the precious vitae of their Primarch to continue his experiments.

Black Tide

Having finally secured their homeworld against Bile's mutant-creations, Lord Commander Dante assigned Sergeant Rafen the vital mission of recovering the missing phial that contained the blood of their Primarch that had been secreted away by Bile during the Blood Angels' conclave. Rafen was to recover this most precious of resources and execute the one who stole it for his foul transgressions. Rafen futilely followed the trail of Fabius Bile aboard the Strike Cruiser Tycho for some time, but the trail had gone cold. With the help of Sergeant Noxx of the Flesh Tearers Chapter, the two noncommissioned officers were able to combine their squads and redouble their efforts in tracking and hunting down the elusive Bile. Eventually, the Clone Lord's whereabouts were traced to a powerful Adeptus Mechanicus Magos by the name of Matthun Zellik who had prior dealings with Bile in his usurped identity as the Magos Haran Serpens, the same alias used by Bile to infiltrate the Blood Angels' fortress-monastery on Baal. The joint Space Marine strike force attacked the vessel Archeohort, an ancient and unusual excavation ship solely manned by Servitors and members of the Skitarii.

Rafen and Noxx were able to take advantage of a turncoat within Zellik's retinue, and were able to make their way to Zellik's trophy room. They were able to force the Magos' surrender when they began to smash and destroy the relics he had recovered during his long career. With the vessels Archeohort, Tycho and the Flesh Tearers' vessel Gabriel, Sergeat Rafen and his Battle-Brothers traveled to the world of Dynikas V, a world in the Ghoul Stars region, where Magos Zellik had last had dealings with "Magos Serpens." This unusual world had fallen victim to the predations of a tendril of a Tyranid Hive Fleet, but due to unusual events, somehow the oceans remained intact. Within the oceans of the ravaged planet lurked several aquatically evolved Tyranid bioforms, who were now leaderless without a Hive Mind to control them. Thanks to a captured Zoanthrope Bile "modified", the pheromones produced by the creature were used to confuse the Tyranids and hide the existence of Bile's facility from their senses.

Sacrificing Magos Zellik's ship, Sergeants Rafen, Nox and their men descended upon the planet using a submersible to approach Bile's suspected base of operations. But the mission soon went awry when the Space Marines were forced to battle enormous Tyranid creatures that rivalled the mighty Ice Krakens of the Death World of Fenris. During their nautical battle, Rafen was somehow separated from his allies and managed to float to the surface where he was captured by Bile's enhanced, mutated slaves and brought to the Clone Lord's laboratorium within his bleak fortress complex. Disarmed and strapped to an examination table, Rafen had a strange maggot implanted into his body that bound itself to him and was taken before Fabius Bile himself.

The Emperor Project

"The Dark Gods and their slaves have nothing to offer me now, but I have far more to offer them."
— Fabius Bile
Bile's Enhanced Warriors

Bile's enhanced warriors on the battlefield

The Clone Lord began to espouse his grand scheme to use the highly pure blood of Sanguinius to help him in his most audacious scheme: obtaining the complete genetic code of the Emperor of Mankind and creating a replicae (clone) of him -- that Bile would control -- with all of the Emperor's psychic powers and other attributes, though none of his moral sense. For millennia, Bile had been collecting body parts and genetic material from captured or killed Space Marines to further this project, the ultimate goal of his quest for human perfection begun so long before. Sanguinius' blood, carrying a purer strain of the Emperor's DNA than that of the genetic material reaped from the gene-seed organs of countless Astartes, was a huge leap forward for Bile's ambitions. Though severely wounded and weakened from his recent ordeal, Rafen managed to attack the wretched Bile and tear out his throat with his teeth, killing him.

However, unbeknownst to Rafen, Bile was not actually dead. Following this assassination, Rafen was taken to a bizarre arena where he was forced to take part in a race against mutants and other captured Astartes, lest he be killed. During this contest, Rafen saw Bile in the audience, somehow still alive. During this contest, Rafen encountered the bellicose Tarikus, a captured Doom Eagles Space Marine, and conspired with him to effect an uprising against the Clone Lord. Meanwhile, Sergeant Noxx had taken charge of the joint Space Marine strike force and effected an assault upon Bile's fortress complex. During the ensuing battle Brother Ceris, a Librarian in Rafen's squad, psychically contacted his squad leader and bade him to assault a strange Warp signature to prevent Bile from effecting his escape. This strange Warp signature proved to be a captured Zoanthrope that had been harvested by Bile and bent to his will to create Warp portals and ward away the other Tyranid bioforms on the planet. The Zoanthrope welcomed oblivion at the hands of the Blood Angels Sergeant.

During the battle that ensued, Fabius Bile was killed no less than four times. The truth of the matter was revealed to Rafen and a handful of his allies when they encountered a pair of clones of Bile; apparent copies of the true Fabius Bile who was not even on the planet. Though unfortunate, when confronted, one of the Bile clones did possess the coveted phial of Sanguinius' blood. When Rafen fought the last Bile clone he managed to take it from the clone and inject it into himself, temporarily attaining enormous strength and power from the blood of Sanguinius. Bile had told Rafen that he did not need the blood anymore, as he had analyzed it already, and had grasped its genetic secrets. The Space Marines then effected their escape by teleporting away from Dykinas V while the Tyranid bioforms ravaged Bile's fortress complex in the absence of the captured Zoanthrope who had been keeping them at bay.

Following these events, the presumably "real" Bile is still alive and well on an Eldar Crone World. His knowledge of the Emperor's DNA is intact, but the replicae project has suffered major delays thanks to the Blood Angels and Flesh Tearers' actions. He was offered an alliance with the Daemon Prince Malfallax to take revenge against the Blood Angels, although it is not currently known whether he accepted the offer.

The Primogenitor Primaris

Fabius Bile first learned of the existence of the Primaris Space Marines in the days after the birth of the Great Rift while upon the world of Agrathane Excellia. There he witnessed a strike force of Primaris Space Marines in action during a campaign of the Indomitus Crusade. Attacking from above, a strike force from the newly founded Nemesors Chapter captured a fortified Black Legion bastion complex in the space of a single solar hour. Impressed despite himself at the genetic artistry of Belisarius Cawl, Bile develops an obsession with the capture and dissection of these statuesque warriors. His intent is to blend them body and soul with the dark energies of Chaos in order to breed his own twisted versions of Primaris Space Marines.

The Phoenician's Clone

At some point before the start of the 41st Millennium, Bile finally succeeded at cloning one of the Primarchs, in this case his own genetic parent, Fulgrim. This version of Fulgrim, unlike all of Bile's previous attempts at recreating his sire, was an exact copy, as pure as the original before his corruption by Slaanesh. Why this clone of Fulgrim was untainted remained a mystery even to Bile.

As the Primarchs had originally been created to do, the new incarnation of Fulgrim aged to maturity rapidly, and because the Emperor had gifted His sons with the capacity for genetic memory, this version of Fulgrim also remembered all the events of the Great Crusade and the Horus Heresy.

This version of Fulgrim expressed great regret for his actions during those conflicts and his eventual turn to Chaos, and he swore that he would do all that he could to atone for his sins, his murder of Ferrus Manus, and his betrayal of the Emperor's cause. Instead, before he could undertake any actions, Bile betrayed his creation into the hands of the Necron Overlord Trazyn the Infinite. The resurrected Primarch became a part of the Necron's collection of important historical figures on his Tomb World of Solemnace. Bile feared that for all the cloned Fulgrim's passionate condemnations of his daemonic counterpart's actions, this Fulgrim truly WAS the same man, and would end up making all the same mistakes and poor choices as before.


Fabius Bile The Clone Lord

Fabius Bile

Fabius Bile wears his white hair bound in a long scalp-lock, which only serves to render his already gaunt features more skeletal and emaciated. His eyes are black, having changed to match those of his Daemon Primarch, Fulgrim. Bile wears a floor-length coat of flayed human skin, taken from the bodies of the dead on Istvaan V. Here and there, it is possible to recognise the features of a face, a mouth stretched in an endless scream of agony or eyes wide with horror at the sight of the skinner's knife. Fabius also favours a belt of knotted sinew pierced through with metal loops, from which hang the tools of the Excruciator's art. These include hooks, blades, spikes, pliers and barbs glittering with the promise of excruciating and exquisite pain.



The infamous Clone Lord, arrayed in his fearsome panoply of Chaos

  • Chaos Artificer Power Armour - Fabius Bile's Chaos-tainted Power Armour contains multiple devices of his own invention intended to fill his veins with powerful stimulants and pain killers that make him more effective in combat and which transform all the pain he feels into a form of pleasure in the best tradition of Slaanesh.
  • The Chirurgeon - Possessed of a darkling sentience of its own, this complex part-sorcerous/part-technological device is attached to Fabius Bile's spine and extends its spidery limbs over his shoulders. It pumps life-giving ichor around his body, charged with the immortal energy of the Warp itself, resulting in vast variations on his strength and other abilities. It often gives him many of the immunities enjoyed by daemonkind whilst boosting his physical abilities to superhuman levels. On the battlefield, he might also bestow the questionable gift of his enhancements to others, with uncertain results. Sometimes the experiment is a success, creating psychotic killers superhuman even in comparison to their corrupted Chaos Space Marine brethren, but sometimes the subject's metabolism disintegrates in the face of the stress, resulting in instant death. This is a construction of Fabius' own invention and he has perfected it over a long period of time to more intimately bond with his body, enabling him to even perform surgery on himself with his own contraption.
  • Rod of Torment - The hell-forged Rod of Torment is a specially-crafted close-combat weapon that was once a sceptre of office belonging to the Daemon Prince Sh'lacqclak, Marquis of Mutilation. Reforged to Bile's own purposes, the Rod amplies the slightest touch into a raging maelstrom of agony. Though Fabius sees the device as somewhat blunt, it always raises a flicker to send a victim screaming for the release of death just by administering a deft rap on the knuckles.
  • Xyclos Needler - Bile also employs other obscure or Archeotech weaponry, such as the Xyclos Needler, a specially-crafted weapon created so that he could "test" new genetically-engineered serums in battlefield conditions. It fires a thin capillary tube imbued with Bile's latest creation. Even the smallest scratch can induce terrifying psychotic premonitions of the tortures yet to come, cause a living being to mutate uncontrollably, or even to cause the victim to spontaneously combust.
  • Bolt Pistol
  • Enhanced Warriors - Fabius Bile is known to make use of enhanced warriors drawn from a pool of willing Chaos Space Marines who have been altered through the use of genetic manipulation and specially crafted drug cocktails. These squads of "enhanced warriors" do not always perform as well as he hopes. Sometimes their mutations are stable, enhancing their strength and fortitude on the battlefield beyond the norms of regular Astartes, but at other times become ravenous, out-of-control monsters.


Inspiration-wise, Fabius is an amalgamation of various "mad scientist" figures from both the real world and fiction, from the Nazis' Josef Mengele to Dr. Victor Frankenstein. The etymology of Fabius Bile comes from the Latin word Fabius, which is the name of a Patrician Roman gens and Bile, from Latin bīlis ("bile"). In biochemistry bile is a bitter brownish-yellow or greenish-yellow secretion produced by the liver and stored in the gall bladder. The word Bile also means bitterness of temper; ill-humour; irascibility.
