- "I am the Arch-fiend, the Despoiler of Worlds, and by my hands shall the false Emperor fall."
- — Abaddon, Warmaster of Chaos
Abaddon, also known as Abaddon the Despoiler, once named Ezekyle Abaddon, is the Warmaster of Chaos, a Chaos Lord and the greatest Champion of Chaos Undivided in the galaxy. He is the commander of the Black Legion of Chaos Space Marines and is rumoured to be the clone-progeny of the Warmaster Horus, the greatest Traitor in Imperial history, and at one time his most favoured son amongst the Space Marines of the Sons of Horus Legion. He is now infamous for leading Black Crusades, the terrible military campaigns during which the normally fractious Forces of Chaos unite under his leadership and launch a massive attack against the Imperium from within the Eye of Terror. The most recent of these attacks, the 13th Black Crusade in 999.M41, led to the partial capture of the vital Imperial Fortress World of Cadia and an expansion of Chaos-controlled space into Imperial territory for the first time since the Horus Heresy.
In the days of hope that preceded the Horus Heresy, Ezekyle Abaddon fought amongst that most noble of brotherhoods, the Legiones Astartes. Originally the firstborn son of the most mighty of Cthonia's gang warlords, Ezekyle killed his father in single combat after a disastrous Cthonian coming of age ritual. Though he lived in exile after that point, his massive build and natural ferocity saw him grow to be a legend amongst his people. Before long, the vicious young warrior came to the attention of the Luna Wolves Space Marine Legion, and he was recruited into their brotherhood. Within the space of a few short years Abaddon had distinguished himself on the training grounds and fought his way through the echelons of the Luna Wolves to be given the newly founded rank of First Captain. After the development of new and powerful war-technology by the Mechanicum, Abaddon was gifted a suit of custom-made Cataphractii Pattern Terminator Armour to accommodate his mighty stature. So powerful a warrior had Abaddon become that he was used as a military model for the entire brotherhood of the Luna Wolves' elite 1st Company, known as the Justaerin. With a long history of victories behind him, Abaddon was soon respected as a leader and fighter alike, for he waged war like the warrior kings of old. Better yet, he earned a place at the right hand of Horus Lupercal, most favoured of all the Primarchs. He became a lord of the new superhuman elite who were to redefine the course of human history; at first to the betterment of the Imperium of Man, and later to its tragic downfall.
By the time of the Great Crusade, Ezekyle Abaddon had been recognised as the greatest warrior of the vaunted XVI Legion after their Primarch Horus. He was blessed with being able to serve at the right hand of the Primarch himself, for to witness such a being in the flesh was to be in the presence of a demigod. Abbadon was the first and most respected of them all, a man who worshipped his Primarch as a god, just as Horus worshipped his father the Emperor of Mankind in turn. Horus Lupercal was raised up by the Emperor Himself as the greatest of all the Primarchs' number, an accolade never surpassed before or since. Yet amongst Horus' many virtues was his humility. He listened well to the counsel of his warriors, learned from his mistakes, and considered every action before committing to it. Amongst his advisers in the Luna Wolves, he trusted four officers above all. This council of warrior captains was known as the Mournival. At the time of the Horus Heresy's beginnings it was comprised of Abaddon himself, Tarik Torgaddon, Captain of the 2nd Company, Horus "Little Horus" Aximand, Captain of the 5th Company and Garviel Loken, Captain of the 10th Company.
It was after the battle for the world designated Sixty-Three Nineteen by the XVI Legion, in which Tenth Captain Garviel Loken managed to reach and slay the impostor Emperor who ruled the world ahead of Abaddon, that the First Captain recommended Loken's elevation into the Mournival to replace the 4th Company's Captain Hastur Sejanus. Sejanus, a particular favorite of Horus, had been slain shortly before the battle.
As the Great Crusade conquered its way across the stars, it reunited many of the scattered domains of Mankind that had been abandoned and isolated by the chaotic tides of the Warp. Always at the fore was Horus Lupercal, with Abaddon at his side. They were the first into battle, the first to exhort their brother Legions to acts of greatness, and the first to encounter the strange new threats that had grown in the dark corners of the galaxy. One of these threats was a danger so insidious that it slowly corrupted many of the Legiones Astartes, including the Primarch Horus himself.
Abaddon was also a member of the Legion's Warrior Lodge, the "quiet order" within the Luna Wolves, inspired by similar lodges on the Feral World of Davin -- which the Luna Wolves had brought to Imperial Compliance many years earlier. Erebus, first amongst the Chaplains of the Word Bearers Legion and first amongst the worshippers of the Chaos Gods, had spread his secret warrior lodges to the brethren of the Luna Wolves as well as many of the other Space Marine Legions. In the daylight hours, those of the Legiones Astartes who had secretly come to worship Chaos used their twisted logics to sway more of their number to their cause.
During one particular Imperial Compliance action, Abaddon notably stood against Horus' attempts to negotiate with a stray branch of humanity known as the Interex, preferring to adhere to the Emperor's stated policy, and simply demand surrender or force Imperial Compliance upon newly discovered human cultures. This attitude was reversed in desperation after Horus was critically injured by the Chaos-corrupted Imperial Planetary Governor Eugen Temba upon the XVI Legion's return to the world of Davin. Horus was mortally wounded after slaying the Nurgle-corrupted Temba upon the bridge of his downed starship on Davin's moon, which had been transformed by Nurgle's corruption into a reeking swamp infested with undead Plague Zombies, Temba's own former Imperial Army garrison. Temba had wielded a blade dedicated to Nurgle known as the Kinebrach Anathame that had infected the Primarch with a toxin so virulent that even a Primarch's superhuman immune system and all the advanced technologies of his Legion's Apothecaries could not defeat it.
Blinded by grief, Abaddon and his fellow comnpany captains took the Primarch's body on the advice of the Word Bearers' First Chaplain Erebus to a mystic healer who belonged to the Chaotic Temple of the Serpent Lodge on Davin and who was actually a Chaos Sorcerer -- an act in utter contradiction of the Imperial Truth (which was stridently atheistic) and which opened Horus up to the influence of the Ruinous Powers of Chaos. Yet instead of salvation, the priests of that Davinite moon brought eternal damnation. When Horus emerged, a change had been wrought in him, and a shadow lurked behind his eyes that would never leave. The seed of bitterness that had been planted in Horus’ heart ultimately blossomed into a fullscale heresy that nearly tore the Imperium apart.
Following Horus' corruption by Chaos and his resurrection through its profane power, Abaddon backed his Primarch to the hilt and firmly aligned himself with Horus against the Emperor, ultimately giving his soul over completely to the service of Chaos Undivided. Horus, under the guise of putting down the religious rebellion against Imperial Compliance on the world of Istvaan III, amassed his troops in the Istvaan System. The corrupted Warmaster had a plan by which he would destroy all the remaining Loyalist elements of the Legions under his command, a plan that would ultimately unfold into the nightmare of what Imperial scholars would later name the Istvaan III Atrocity. During the resulting campaign of attrition, Abaddon was responsible for the wounding and abandonment of the Loyalist Captain Garviel Loken within the ruins of the Istvaanian capital known as the Choral City, although Loken survived the combat and witnessed the beginning of the orbital bombardment of the planet and the remaining Loyalist Astartes on it by the Traitor Legions' fleet on Horus' orders.
Throughout the seven brutal standard years of the terrible Imperial civil war that was the Horus Heresy, First Captain Abaddon led the elite squad of the renamed Sons of Horus Space Marines from the 1st Company known as the Justaerin, who wore singular black-coloured Cataphractii Pattern Terminator Armour. Abaddon led this elite unit during many of the most infamous actions by the Forces of Chaos during the Horus Heresy, including the Drop Site Massacre on Istvaan V, the battle against the Loyalists on Yarant as well as in the climactic Battle of Terra. Yet the Warmaster fell at the last. As he duelled his once-beloved gene-father, the Emperor, upon the bridge of the Vengeful Spirit, Horus' flagship, the Warmaster was vanquished by a psychic blast. Abaddon and his most heavily-armed warriors fought their way through squad after squad of yellow-armoured Imperial Fists Terminators to the command centre of the starship, but they were too late. Running across iron decks that were slick with the blood of demigods, Abaddon took up the lifeless body of his father with great tenderness. Wracked with emotion, Abaddon detached the taloned claw that Horus had used to kill the Primarch Sanguinius from his Primarch's armour and resolved to use it to one day throttle the Emperor Himself.
With his gene-father dead, Abaddon abandoned the conquest of Terra and instead retreated with the Sons of Horus Legion and all of their remaining assets, Legion slaves and starships, blazing a trail across the stars to the forbidden realm of the Eye of Terror. The Traitor Legions retreated in his wake, cursing the hour that had stolen their destiny. With this act, Abaddon passed from mortal space and into legend.
Rise of the Black Legion
- "Speak not to me of Abaddon, blackest of hearts, basest of fiends. Who else amongst the hosts of the traitors embraced damnation with such a fierce glee?"
Following the dire events of the Horus Heresy during the final epic Battle of Terra and the death of the Warmaster Horus aboard his flagship, the Vengeful Spirit, First Captain Abaddon and the surviving Sons of Horus broke orbit over Terra and fought their way free of the battle and escaped into the void. A time of reprisal and retribution known as the Great Scouring followed, and countless worlds were put to death by the Loyalists for siding with Horus, their corpses left as a warning to others. Those Traitor Legions that remained in the Imperium were hunted mercilessly and hounded across the stars by pitiless Loyalists. Abaddon and the remaining Sons of Horus took refuge in the Eye of Terror, choosing to plunge into that maelstrom of madness rather than face extinction at the hands of the Emperor's vengeful warriors.
The Sons of Horus managed to reach the Eye of Terror with the bloodied survivors of the Scouring, but the once mighty XVI Legion was reduced to a fraction of its former size. Led by only a few remaining captains, the Legion struggled with its loyalty to their fallen Primarch and the cold reality of their defeat at the hands of the Emperor and His lackeys. Bereft of their glorious Primarch, the Legion floundered, and in desperation turned to each of the Chaos Gods in turn in their search for renewed power, inviting daemonic possession and the ever more costly blessings of the Warp. All the while, the Legion suffered the jealous attacks of their former allies. As the Traitor Legions turned upon one another, the Dark Gods subverted and manipulated their new playthings, reshaping the Legions for their own ends and the never-ending war between the gods.
Ezekyle Abaddon abandoned the Legion; broken by the death of Horus and sick of war, he wandered alone into the Eye of Terror. Meanwhile the Sons of Horus carried the body of their Primarch, preserved in stasis, further into the Eye, ignoring the wars that raged around them. On the Daemon World of Maeleum, a graveyard world of steel and rust, the Sons of Horus raised a fortress, fashioning a mighty citadel from the wrecks of decaying vessels lost to the Warp with the aid of the thousands of slaves they had taken from the worlds of the Imperium. The Legion interred Horus' body within a great tomb, where many fell into worship of their fallen demigod. The Sons of Horus' installation on Maeleum served as both a tomb for their lost Primarch and a fortress from which they would launch further attacks upon both the Imperium and their fellow Traitor Legions. All the while, the XVI Legion suffered the jealous attacks of their former allies amongst the Forces of Chaos as the brief unity between the Dark Gods and their servants during the Heresy once more broke down into the normal state of internecine rivalry, unleashing the Slave Wars.
With their Primarch dead and their Legion on the verge of extinction, the Sons of Horus stagnated. Some captains suspected that it would be but a matter of time before they and their Battle-Brothers were drawn into the wars between the Traitor Legions, and so they pushed for the Sons of Horus to replace its losses by increasing the Legion's gene-seed stocks. These same captains knew that any fortress, no matter how grand, could not hope to hold back a determined Space Marine assault, and called for more warriors to be found. Unfortunately, the majority of surviving captains were convinced that the Warp would provide all the power they needed, if only they could master the methods of merging daemon and Space Marine.
The wars between the other Legions who had sided with Horus during the Horus Heresy raged across the Eye of Terror even as the Sons of Horus ignored the events happening around them, and continued to raise their fortress ever higher, worshipping the corpse of their Primarch. The Sons of Horus had remained largely apart from these conflicts; however, jealous eyes now turned their way. Traitorous forces gathered against them and conspired to rob them of the remains of Horus to further vile and selfish ambitions. The Primarch Horus' body, with its potent genetic information and biological secrets, 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 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, some say with the purpose of handing it over to the dark Apothecary Fabius Bile who intended to clone it in order to create a new and still greater Warmaster of Chaos to restore the Traitor Legions' unity and fortunes.
Vanquishing the Past
- "Horus was weak. Horus was a fool. He had the whole galaxy within his grasp and he let it slip away."
Their fortress in ruins and their Legion decimated, the Sons of Horus stood on the brink of vanishing forever from the galaxy and fading into cursed memory. The XVI Legion devolved into in-fighting amongst themselves, giving in to dark despair or uncontrolled rage. The divisions between the Legion's captains turned into bitter bloodshed and murder, as order completely collapsed. The salvation of the Sons of Horus came when one of its greatest captains, Ezekyle Abaddon, returned from his Dark Pilgrimage in time to watch the battle from afar. It was in that moment that he saw, with cold clarity, that it was Horus' failure that had led the Legion here, to them tearing each other apart in the blood-soaked ruins of Maeleum. Abaddon swore that he would succeed where Horus had failed in overthrowing the "Corpse-Emperor" and proclaimed himself the new Warmaster of Chaos. Finally, sickened by how far the Legion had fallen, he stalked through the ruins hunting down his fellow captains, cooling his rage with their final screams. In the end, Abaddon alone remained of the Legion's leaders, demanding obedience from his brothers.
Some saw Abaddon as Horus' rightful successor and fell at his feet willingly, while others recognised his raw strength and bowed their heads to his might. A few turned their back on Abadodn, and were either cut down by their brothers or managed to escape into the Warp. With his Legion brought to heel, Abaddon turned his attention to the clones of Horus; he commanded his warriors to extinguish all trace of their former Primarch and free themselves from his shadow. He then personally led an attack on the Emperor's Children that destroyed the body of the Primarch Horus and all its clones, and in so doing, ushered in a new age for the XVI Legion. He had the Sons of Horus repaint their viridian Power Armour black, the colour of mourning and of vengeance, and cast-off the XVI Legion's former moniker of the Sons of Horus. From then on, they became known as the Black Legion. Through his actions, the Despoiler had reinvigorated the Legion, reviving the old notion that none could stand in their way and that they stood first amongst the Traitor Legions, destined by the will of the Dark Gods to one day inherit the galaxy itself. When the warbands of the Black Legion and the other Forces of Chaos gather under the wrathful banner of Abaddon the Despoiler to unleash yet another of their Black Crusades to overthrow the False Emperor, the words of Horus are heard upon their lips -- let the galaxy burn. The Long War for control of the galaxy by Chaos and the Black Legion had begun.
The Folly of Drecarth
When Abaddon ascended to command of the Sons of Horus, not every warrior of the XVI Legion swore allegiance to him. Many of the Traitors clung to their worship of Horus as a god, believing that he would one day return to lead them and punish those who had forsaken their oaths. Others considered the Horus Heresy to be the end of their subservience to gods and masters; the Emperor and their Primarch were the last overlords they would ever bow down to and they saw no reason to make an exception for Abaddon. Most of these Renegades were gradually lost to the Warp, disappearing into the Eye and vanishing from record, though some prospered and would return to be a thorn in the side of Abaddon.
One of these splinter warbands was the Sons of the Eye, led by Drecarth the Sightless. A former Battle-Brother of Abaddon's, Drecarth had been one of Horus' captains, escaping in the chaos after Maeleum fell. Abaddon had heard whispers of Drecarth's escape and treachery from his cabal of Chaos Sorcerers, who also claimed that an old ally would one day rise to subert the Black Legion, twisting its loyalty with the memory of the dead Primarch. So, under the guise of truce, Abaddon made a pact with the Sons of the Eye and allied with them during the 6th Black Crusade in 901.M36. Abaddon wanted to make an example of the Sons of the Eye, a dire warning to any that would consider challenging his power, but he needed to set the stage for his vengeance just right so that none would ever doubt his resolve.
During the 6th Black Crusade, Abaddon besieged the Imperial Forge World of Arkreach, offering Drecarth and his Sons of the Eye an equal share of the plunder. For months, the two forces of Chaos Space Marines fought side-by-side against the defences of the Adeptus Mechanicus, bombarding their great forge cities from space. Finally, the Traitors stood triumphant in the smouldering ruins of the great manufactoria, dead littering the ground. As Drecarth extended his hand in greeting, Abaddon grasped it with his own, only to thrust the claws of the Talon of Horus into his fellow Chaos Space Marine's gut. Drecarth lived long enough to see the Sons of the Eye bow to Abaddon and be reabsorbed into the Black Legion before the Warmaster of Chaos tore out his skull and spine. Thus did Abaddon deliver a dire warning to any who dared challenge his power.
A New Champion
His control secured, Abaddon started expanding the ranks of the Black Legion, consumed by the desire to launch an assault against the Imperium. Word spread across the Eye of Terror that any Space Marine who bowed before the Despoiler would be granted a place in his Black Legion and a part in his grand plan for revenge against the False Emperor. Many of the other Traitors mocked and derided Abaddon for his arrogance. However, the endless wars and corruption of the Warp had sown disillusion in the hearts of others and the promise of a place in a Legion led by a warlord determined to continue the war against the Imperium appealed to a great number. The insulting defeat at the hands of the Loyalist Space Marine Legions was still fresh in the minds of many of the Chaos Space Marines, and they hungered for a chance to spill the blood of their former brothers. Other Traitor Legionaries cared not whose blood they spilled, only that Abaddon could lead them to worlds where they could tear piteous screams from the dying and crush the corpses of their foes underfoot. The legend of Abaddon was also spreading, and those Traitor Marines who respected only strength, cruelty and dark majesty already marked him out as a Chaos warlord to rule all others.
Abaddon soon earned an enduring reputation among the Traitor Legions for the terrifying vengeance he visited upon those who betrayed him. Some Traitor Legionaries and daemonic warlords attempted to use the Black Legion for their own ends, infiltrating its ranks with false promises of loyalty. Others attempted to whisper promises in the ears of those that had sworn fealty to the Black Legion and tried to turn them against the Despoiler. In the end, the heads of all those Chaos Champions and Chaos Lords adorned Abaddon's trophy rack, their warbands destroyed and their fortresses torn down stone by stone. Eventually, only the very foolish or terminally insane would break their oath to Abaddon the Despoiler.
The new Warmaster was a master of manipulation and knew just what combination of fear, greed and vanity would sway the minds of both men and daemons. Warlords would come before Abaddon merely to verify this Champion of Chaos and his Black Legion for themselves, but found themselves scorching their armour black and joining his cause. As the numbers of the Black Legion swelled, Abaddon ravaged the worlds of the Eye of Terror with his fleet, claiming more warriors and slaves for his cause. This time, the Despoiler was careful not to create such an easy target for his foes, and the Black Legion remained a fleet-based formation, slipping like shadows across the Warp. Aboard the Vengeful Spirit Abaddon led his war against the other Traitor Legions, their allies and their enemies, creating an army to rival any force in the galaxy.
Such is the nature of the Traitor Legions that no individual warlord could ever rule over all of them, but Abaddon hoped to one day unite them toward a single goal as Horus had done before him. The Black Legion could only hope to destroy the Emperor and His Imperium with the help of the other Traitor Legions, combining to brush aside the armies ranged against them and launch a single massive assault on Terra. This was Abaddon's dark dream and the path that would shape his destiny for centuries to come.
While other Chaos Space Marine warlords were content to make pacts with individual Chaos Gods and daemons, eagerly giving up control for a sliver of power, Abaddon was different. In the long decades of the Great Crusade and the bloody years of the Horus Heresy that followed, he had studied the way in which Horus had waged his wars and dominated his allies. What Abaddon observed was, first, the hand of the Emperor and then later the influence of the Dark Gods at work, limiting the greatness of his Primarch and ultimately leading to his demise. Abaddon would make no such mistake, and though he would court the Chaos Gods as allies, he vowed, foolishly perhaps, never to be completely in their thrall.
It is still unclear how Abaddon was able to use the will of the Dark Gods for his own ends while remaining unscathed by their power. Some say that it is the blood he shares with Horus, fuelling old rumours that he was the Warmaster's one pure clone son. Others say that Abaddon was broken in some fundamental way by the death of his Primarch and the defeat on Terra, his mind consumed by hatred and rage until nothing of his humanity remained. Another tale maintains that Abaddon was never human at all and is instead a construct of the Dark Gods -- an expression of their hatred for Mankind. Whatever the reason, the Ruinous Powers chose Abaddon to be their champion and gifted him with a freedom of will denied to so many of their servants, perhaps impressed by the audacity and grandeur of his vengeance.
Regardless of how this favour was won, the period after the destruction of the clones of Horus during the Slave Wars and the renaming of the Sons of Horus was a time of war and domination for Abaddon and the Black Legion. As it grew in size and strength, it exerted its power over the other Chaos Space Marine warbands within the Eye of Terror, crushing and absorbing countless lesser warbands, bending them to the will of the Legion and adding their strength to its growing ranks. Meanwhile, Abaddon also sought other ways both to increase his personal power and to learn all he could about the new and dangerous realm in which the Traitor Legionaries found themselves. The Despoiler had already discovered much during his own Dark Pilgrimage, the journey he took in the lost years between the end of the Horus Heresy and his return to the ruins of Maeleum. On his travels, he had learned that the power that daemons represented and embodied could be harnessed and controlled, just as one man might control another. He also realised that the Eye of Terror was a place containing unnumbered arcane devices, forbidden weapons and lost worlds, the likes of which were unknown to much of the galaxy -- and that many of them could be turned to his ends.
The Black Crusades
In 781.M31, five centuries after his retreat from Terra, Abaddon returned to Imperial space at the head of a host of Traitors and daemons. It was the Imperium's first encounter with the newly founded Black Legion and the return of a brutal and bitter enemy many had thought lost to the graveyard of history. Since the Great Scouring, Abaddon had remained within the Eye of Terror, rebuilding the Black Legion as a vengeful reflection of its former glory. At last, the Black Legion and the other Traitors returned to realspace, the first chapter in their Long War against the Emperor ready to be written in the blood of Imperial worlds. Through alliance, threats and promises, Abaddon was able to muster the largest force of Traitor Legions seen since the Horus Heresy and took the Imperium by surprise. Worlds close to the Eye of Terror fell into mayhem and chaos as Legions descended from the sky and daemons tore their way into reality. Only Cadia, with its formidable defences, stood firm, its brave regiments fighting from the towering gates and bastions of their cities.
To counter the invasion, the Imperium was forced to divert many of the newly-formed Space Marine Chapters of the Second Founding from war zones across the Segmentum Obscurus. The Traitor Legions basked in their return from the Eye of Terror, bathing in the blood of innocent worlds and filling the holds of their voidships with slaves. On a dozen planets, the Black Legion proved worthy of their fallen Primarch and the martial prowess of the ancient Luna Wolves. Abaddon had chosen his generals well, and each competed for glory as the Legion tore a bloody gouge across the stars. The Black Legion's greatest achievement was not only its brutal victories, but also the unity it had managed to forge among the Traitors and their daemonic allies. Even though the Traitor Space Marines, daemons and Heretics turned on each other once Imperial resistance had been crushed, in the presence of the Black Legion, they gave grudging respect. This was the Legion of fear and domination Abaddon had wrought, and it was to be an ominous sign of things to come for the Imperium.
In what would become a festering thorn in the side of the Imperium, the Traitor Legions, often led by the Black Legion or even Abaddon himself, would repeatedly spill out of the Eye of Terror to burn and pillage entire sectors. In the light of dying stars and flaming cities, the Black Legion would indulge their hatred of the Imperium, indiscriminately killing the servants of the False Emperor and tearing down anything they saw as a symbol of the Corpse-God. During these so-called "Black Crusades", whole star systems would be destroyed in conflicts that would drag on for standard decades or centuries until, as suddenly as they had appeared, the Black Legion would retreat into the Eye of Terror, their holds filled with slaves and plunder. The Segmentum Obscurus suffered terribly in these endless wars against the fallen Space Marine Legions, but in truth nowhere was safe from their treacherous reach. This was something the Black Legion proved time and again as it cemented its infamous reputation among the armies of the Imperium as a pitiless foe.
The Tower of Silence
As the bloodshed of the 1st Black Crusade reached its frenzied heights, cities burned and worlds were stripped of people to feed the dark desires of the Traitor Legions. Leaving his Black Legion to continue their brutal reprisals and raids against Imperial worlds, Abaddon pursued his own plans. Using the howling souls unleashed into the Warp by so much death and destruction, he made a secret daemonic bargain. In payment for the feast of despair, pain and anguish Abaddon had created with his Black Crusade, the Dark Gods gifted him with knowledge of the secret location of the Tower of Silence on the world of Uralan.
Cloaked in the shadow of the Eye of Terror, Uralan was whispered of in daemonic lore as a place where the gods themselves locked away their secrets. Following strands of fate unravelled by his cabal of Chaos Sorcerers, Abaddon had discovered a concealed path through the Warp and across the shifting sea of worlds beyond to reach Uralan without needing to breach the Cadian Gate. With a cadre of the Black Legion's elite warriors, each one a brutal veteran of a thousand battles, Abaddon set foot on Uralan and entered the Tower of Silence. Almost at once, the tower's guardians set upon them, ancient constructs of dark energy that shifted and flickered, their claws tearing at the ragged edges of his warriors' souls.
After the bitter battle, Abaddon climbed down into the mirrored heart of Uralan. There, Abaddon wandered the massive haunted labyrinth for what seemed an age, fighting off the spirits of the dead that threatened to add him to their ranks. Eventually, Abaddon made his way towards the centre of the labyrinth where a shard of shifting darkness hung suspended in the air. Reaching out into the void, Abaddon felt the cold hilt of a blade meet his palm and he pulled it into reality; the Daemonsword Drach'nyen took terrible shape before his eyes. After the recovery of the malefic sword, Abaddon's power swelled to inhuman proportions and the new Warmaster of Chaos become nigh unstoppable. Whole cities were burned in sacrifice to the every-hungry daemons of Chaos, and entire armies were torn apart by gibbering Warp entities. Abaddon's power swelled to inhuman proportions as the Gods of Chaos rewarded him lavishly and he undertook acts of fiendish bravery which horrified those who stood against him.
Black Legion Ascendant
Infused with the might of Chaos, the Black Legion grew in power and glory during the 1st Black Crusade. Under the command of Abaddon, they seized ever more victories and triumphs. It was a glorious time for the XVI Legion, as the bloodshed and death of the Crusade washed away some of the memories of the Horus Heresy and their great defeat before the gates of the Emperor's Palace. However, despite the reckless carnage and terrible destruction it caused, eventually, the 1st Black Crusade ended. Responding to the deadly peril, the Imperium had gathered its newly founded Space Marine Chapters and Titan Legions and sent them against the Traitors. Even so, scores of worlds had been silenced forever and millions of slaves were dragged screaming back into the Eye of Terror. Abaddon had tested the defences of his enemies and vastly increased his power with his newly acquired Daemonsword Drach'nyen. He also took to using the title of Warmaster of Chaos, rising to claim all that Horus had once possessed. None within the Black Legion argued Abaddon's right to the title, the 1st Black Crusade proof of his right to lead.
For the Black Legion, their first foray out of the Eye of Terror had done much to restore their position among the Traitor Legions, fostering a new grudging respect for the black armoured warriors and their self-proclaimed Warmaster. If nothing else, Abaddon had proven that the Dark Gods favoured him, something not even the Daemon Primarchs could ignore. Conflict still sputtered and flared between the Traitor Legions, but they now had a new purpose, something they had almost forgotten in the half millennia since the fall of Horus. In the wake of the 1st Black Crusade, a time of constant raiding of Imperial space began. Abaddon was content to give a Black Legion warlord and his warband of Chaos Space Marines the chance to make a name for themselves, allowing them the freedom to strike where and when they would. He fostered this independence on one condition: the atrocities they committed must be done in the name of the Black Legion and at cost to the Emperor.
The Black Legion
Abaddon has long since fought to rebuild the pride and reputation of the warriors he named his Black Legion. At first, he accomplished much through sheer determination and a talent for slaughter that exceeded that of every Chaos Lord outside the gates of Khorne's own fortress. Slowly but surely, Abaddon won the grudging respect of the other Traitor Legions, leading his shattered armies again and again against the reviled Imperium of Man. As his deeds grew mightier and his base of power more solid, Abaddon succeeded in winning their support too. His impassioned words rekindled the Traitor Legions' smouldering hatred of the Emperor on dozens, perhaps hundreds of worlds. As the centuries rolled on, warriors of all the Traitor Legions fought beneath his banner. Those who opposed him were crushed, and those who joined him added their strength to the greatest army ever assembled in the Eye of Terror. When the warbands of the Black Legion gathered anew under the wrathful banner of Abaddon the Despoiler, the words of Horus were heard once more upon their lips — "let the galaxy burn!"
Abaddon has tested the strength of the Imperium many times in the Long War, and with each victory his power grows. Over the millennia, he has led no fewer than thirteen Black Crusades, each of which has emerged from the Warp and culminated in a spectacular invasion of realspace. The first of these saw him recover the Daemon Sword Drach'nyen, a writhing Warp entity that can rend reality wherever it strikes, and every crusade since has seen him destroy a prospective foe or claim another valuable relic for his own. During the 12th Black Crusade early in the 41st Millennium, a conflict better known in Imperial records as the Gothic War, Abaddon unleashed upon the Imperium of the "Corpse Emperor" his newest superweapon, the Planet Killer. This was a massive starship crafted through the amalgamation of Imperial technology and Chaotic sorcery that was capable of destroying entire worlds. However, even this formidable weapon was but a deceit, as Abaddon's real goal behind the Gothic War was not to destroy planets, but to seize the six Blackstone Fortresses, ancient weapons originally created to oppose the Necrons, which the Imperium had found abandoned and used as mere space stations, unable to divine their true purpose. Abaddon's ultimate success was only foiled by the Eldar, who had foreseen his plan through the visions of their Farseers and entered a desperate alliance with the Imperium in order to stop the Black Legion's attempt to seize all of the Blackstone Fortresses. Abaddon was forced to retreat after seizing only two of his six prizes. Though these would prove devastating enough when they were unleashed upon the Imperium nearly a thousand standard years later.
Though the High Lords of Terra believe that these Black Crusades have been repelled, albeit at great cost, they are unaware that each was keyed to a specific goal. As epic in scale as they may be, Abaddon's Black Crusades are but stepping stones, rungs in the ladder that leads to the Despoiler's ultimate vengeance. The destiny the Despoiler has chosen is not that of daemonhood -- though he has been offered the ultimate reward of immortality by each of the Chaos Gods, he has held back from surrendering his soul to their ultimate control. The prize he seeks is nothing less than to tear the Emperor from his Golden Throne upon Terra and, in the process, plunge the Imperium into the darkness of anarchy forever. Without the Astronomican, the psychic beacon with which the Emperor steers His flock across the stars, the Imperium will swiftly collapse into a scattering of cold and lonely worlds, each easy prey for the Despoiler's nightmarish allies.
13th Black Crusade
The last and greatest of Abaddon's thirteen Black Crusades has plunged the crucial Cadian System into a war of unsurpassed intensity. The ninth planet in the system, St. Josmane's Hope, has already been utterly destroyed, and war rages across every district and kasr of Cadia itself. The uninitiated question the Despoiler's motives, for he has ploughed the broad-bladed spear of his invading forces right into the heart of Fortress Cadia and her many-layered defences. Those who know of the daemonic bargains Abaddon struck in the depths of the Eye of Terror realise the true scale of his ambitions. Within the toxic swamps of the Plague Planet, Abaddon bartered the Chaos relic known as the Hand of Darkness for the aid of the gaunt monstrosity Mortarion, Daemon Primarch of the Death Guard, and earned the blessings of Nurgle. Within the surreal, spawn-infested planescapes warped by the power of Tzeentch, Abaddon gained the use of the Rubricae of the cursed Thousand Sons. Within the red bowels of the Goreswirl, the Despoiler duelled the finest of Angron's champions, cutting off their heads one after another with the Daemon Sword Drach'nyen before gifting the Hellfire Stone to the Daemon Primarch of the World Eaters and earning his respect in the process. Upon the flesh-world of Oliensis, the serpentine Daemon Prince Fulgrim swore his aid in exchange for a Pythonian psyker-innocent and the promise of a third-share of those civilians caught in the path of the Black Crusade to come. All that remained was to pave the way for the Daemon Primarchs and their hordes to breach realspace.
Abaddon managed to unite all the Forces of Chaos that exist within the Eye of Terror under his leadership as the Warmaster of Chaos Undivided in 999.M41, after decades of preparation to unleash the greatest Chaotic assault upon the Imperium of Man since the Horus Heresy, more than 10,000 standard years ago. This great campaign, Abaddon's 13th Black Crusade against the realms of the Emperor of Mankind, focused its assaults upon the sectors of the Segmentum Obscurus surrounding the Fortress World of Cadia and the Cadian Gate it protected. The Cadian Gate is the only known free passage through the roiling Warp Storms of the Eye of Terror into Imperial space, and the capture of Cadia would allow the Forces of Chaos their first uninterrupted chance to assault the heart of Imperial space in millennia. In the end, after months of truly titanic fighting that spread across hundreds of worlds and tested the resources of the Imperial military as never before, the campaign wound down in a stalemate. Though Abaddon's Chaotic forces were able to gain a territorial foothold upon Cadia itself, the Imperial Navy's Battlefleets proved to be the victors in the massive void battles that were waged high above the world.
The Forces of Chaos are currently trapped on Cadia and have lost air and space superiority to the Imperial forces, who daily bombard the Ruinous Powers' servants from the air. With several hundred thousand Chaos Space Marines falling upon Cadia in his name, Abaddon has spilt enough blood that the walls of reality are thinning to the point of total collapse. The gates of hell are yawning wide. Abaddon intends to drive the speartip of his Traitor Legions deeper and deeper into the Segmentum Solar, numberless daemon hordes sowing utter destruction in his wake. His ultimate goal is to capsize realspace in a localised swathe of ever-escalating battles that allow the poisonous half-realm of the Eye of Terror to bleed outward all the way to Terra. Once he completes his evil pilgrimage, the Despoiler will dash the "Corpse-Emperor" from His throne of lies and forge an empire of madness in the name of the Dark Gods.
Should Abaddon and his Chaotic allies discover a way to defeat the massive Imperial fleet in orbit over Cadia, the Forces of Chaos would have an open path to drive onward towards the heart of the Imperium and perhaps assault Terra for the second time in its history. As the various Tyranid Hive Fleets are also inexorably moving towards the shining Astronomican beacon of the Emperor's mind that shines out like a light in the darkness from Terra, and the Adeptus Mechanicus reports that the Golden Throne is finally failing, it may well be that the current era of the Age of the Imperium, the Time of Ending, is well-named. In the face of the terrible threat presented by Abaddon the Despoiler and the other enemies of the Imperium, only one true hope may remain for the salvation of Mankind, drawn from the most ancient litany of the Imperial Creed: the Emperor protects...
Chosen of Abaddon
- "Each of Abaddon's chosen have might enough to crush armies, conquer worlds and shake the very foundations of the stars. And yet every time we slay one of their number another warlord of equal strength takes his place. What hope is there in opposing such foes?"
- — The Betrayer of Kaldonia
The Chosen of Abaddon are four powerful Chaos Lords that serve under the patronage of Abaddon the Despoiler, the Warmaster of Chaos and master of the Black Legion of Chaos Space Marines. Rather than a single force with a single leader, the Black Legion became after the Horus Heresy a mighty host of many warbands and warlords. Within this host, all would swear complete allegiance to Abaddon, and through an inner circle, he would lead them with absolute dominion. These favoured lieutenants became known as the Chosen of Abaddon.
The Chosen were his favoured generals, standing above all others and enacting his dark will; a warped shadow of the Luna Wolves' Mournival in which he had once served. Nowhere in the galaxy can a more feared and merciless collection of tyrants be found, always eager to put entire worlds to the sword in the name of Chaos. Nowhere in the galaxy can a more feared and merciless collection of tyrants be found, always eager to put entire worlds to the sword in the name of Chaos. The last recorded deployment of a full Officio Assassinorum Execution Force was against the so-called Chosen of Abaddon. These four individuals were so hated by the Imperium of Man that an entire team of Assassins infiltrated Abaddon's flagship. This was an extraordinary event, for it is rare for even one Assassin to be sent to deal with a threat. Abaddon learned of the impending attack and laid a trap for the Assassins, slaying all four and protecting his Chosen.
The Chosen bear an assortment of titles, reflecting their role in a past Black Crusade or honouring particular acts of cruelty for which they are infamous. Their numbers are ever-changing, for Abaddon has little tolerance for failure amongst those who serve him. The current holders of these four titles are described below.
The Lord Ravager leads the invasion fleets of the Black Crusade. It is he who first makes landfall on the surface of a world.
- Devram Korda - Devram Korda, also known as "The Tyrant of Sarora," is a servant of the Chaos God Slaanesh, the Prince of Pleasure. A former Veteran Sergeant of the Sons of Horus Legion, after the events of the Horus Heresy, he rose to prominence and became a Chaos Lord. He became infamous for his blasphemous actions on the doomed world of Sarora, where he distilled the life essence of the citizens of the planet's largest hive city for a single vial of a sorcerous elixir which made him virtually invincible. He eventually became the current Lord Ravager, the individual who leads the invasion fleets of the Black Crusade in the name of Abaddon the Despoiler. It is Korda who first makes landfall on the surface of a world about to be assaulted by the Forces of Chaos. Korda also commands the personal retinue of the Despoiler, known as the Chosen of Abaddon. In the closing days of the 13th Black Crusade in 999.M41, Devram Korda returned to his master's side, bringing with him two individuals (later identified as Skyrak Slaughterborn and Urkrathos) who had journeyed to the centre of the Eye of Terror. Together with the Chaos Sorcerer Ygethmor the Deceiver, they presented Abaddon with the Heart of Chaos, a powerful artefact that Zaraphiston, a Chaos Sorcerer and rival Chaos Lord of the Despoiler, had long claimed could not exist.
- Ygethmor the Deceiver - Ygethmor the Deceiver, known also as the "Twice Damned" and the "Purgator of Corrialis," is a formidable Sorcerer Lord of the Black Legion. He currently serves as one of Abaddon the Despoiler's lieutenants and a member of his personal retinue, the Chosen of Abaddon. Ygethmor is the current Lord Deceiver, whose visions of the Warp lead the Black Crusade from star system to star system. During the 13th Black Crusade in 999.M41, the Officio Assassinorum sanctioned the deployment of an assassin team to eliminate Ygethmor, amongst other notable targets in service to the Archenemy. Whilst scrutiny of their field records is impossible, at least seven Assassinorum agents are known to have failed in the attempt to take the life of the Deceiver. Ygethmor led the assault of the Forces of Chaos during the campaign known as the Fall of Medusa V in an attempt to become a Daemon Prince. This effort failed and Ygethmor was slain by the blade of the Eldar Autarch Elarique Swiftblade of Craftworld Alaitoc, and those Champions of the Dark Gods who had followed him were left to their fates on the dying world as Medusa V was consumed by an onrushing Warp Storm. However, death rarely represents an end to the service of a Chaos Lord, if the Dark Gods still have use for him. The galaxy may yet suffer the tread of Ygethmor the Deceiver once more.
The Lord Corruptor is tasked with instilling fear and hatred amongst the Chaos Space Marines of the Black Legion. His trophy rack is adorned with the skulls of failed servants.
- Skyrak Slaughterborn - The Chosen of Abaddon lieutenant named Skyrak Slaughterborn, the current Lord Corruptor, leads the warbands of Nurgle within the Black Legion into battle. Collectively known as the Bringers of Decay, they spread their disease and corruption throughout the Realms of Man. Skyrak is known to have led the large warband of Chaos Space Marines known as the Slaughterkin in the assault on Cadia during the 13th Black Crusade.
It falls to the Lord Purgator to ensure that every man, woman and child left alive on a world conquered by the Black Legion is dragged in chains into the hold of the Legion's starships, and that no edifice remains undedicated to the Dark Gods.
- Urkrathos - Within the ranks of the Black Legion are those who are bloody-handed servants of Khorne. Though not a single unified warband within the Black Legion, they are collectively known as the Hounds of Abaddon. Urkrathos, the current Lord Purgator of the Chosen of Abaddon and commander of the Legion's Black Fleet, claims all followers of Khorne within the Legion as his own and directs them according to the will of Abaddon.
Bringers of Despair
Abaddon also formed from the Black Legion's ranks a personal bodyguard known as the Bringers of Despair, among other dark titles. Selected from the strongest and most vicious of his Terminator elite, these fearsome warriors are a terrifying sight, their arrival announcing the presence of the Despoiler himself.
Prior to the Horus Heresy, Ezekyle Abaddon looked up to Horus as his rightful leader and a father figure, equal to, if not above the Emperor of Mankind in his esteem. As the loyal First Captain of the Luna Wolves' 1st Company, Abaddon was proud, irascible and someone who could inspire men to "cry out for Abaddon's return" if he were to die, though Abaddon became inexplicably darker and quicker to anger as the Great Crusade reached its final stage in the early 31st Millennium. Abaddon was prone to panic and desperation when Horus' life was in danger and quick to cast blame on others (such as the Emperor and the Luna Wolves' Apothecary Vaddon, who attempted unsuccessfully to treat Horus after the Primarch was wounded on Davin's Plague Moon).
Initially displaying examples of dogmatic devotion towards Imperial doctrine and the traditional Imperial distrust for anything inhuman or alien, Abaddon followed Horus unquestioningly into service to Chaos and rebellion against the Emperor after the Primarch's recovery from his mortal wounding. Abaddon came to believe that the Horus Heresy was the best outcome for the Great Crusade since it would allow humanity to be ruled by a true leader like Horus rather than a weaker ruler like the Emperor. As he fell more and more under the spell of Chaos, Abaddon came to believe that winning and victory were the only things that matter and that the acquisition of power was the rightful role of the Astartes, since they should rule over their fellow men rather than just serve as their protectors and guardians as the Emperor had intended. The very fact that the Emperor had sought to replace the Primarchs and the Astartes with legions of "mortal" officials and bureaucrats in the governance of the Imperium after the Ullanor Crusade only further convinced Abaddon that the Emperor was a weakling and a fool who did not deserve to rule over Mankind.
Physically, Abaddon was a towering and truly imposing Space Marine, taller even than the vast majority of his fellow Astartes, with a crested top-knot atop his shaven head and the straight nose and wide-spaced eyes reminiscent of Horus' own visage as was common among the Sons of Horus Astartes, though not enough for Abaddon to truly be a doppelganger of the Primarch.
After the end of the Heresy, Abaddon's view of Horus abruptly changed and he came to view the defeated Warmaster with disdain in light of his new view that what truly mattered was the acquisition of power. Abaddon effectively stepped out of Horus' shadow, as was exemplified when he said, "Horus was weak. Horus was a fool. He had the whole galaxy within his grasp and he let it slip away." Abaddon also displayed the psychotic contempt for human life characteristic of most servants of Chaos and was willing to inflict an endless stream of atrocities upon other human beings so long as such actions enhanced his own power and position. Through his martial skill and personal might and the obvious favour he held among the Ruinous Powers after Horus' death, Abaddon won the respect of the other Traitor Legions and proved to be an inspiration to the Chaos Space Marines who dwell within the Eye of Terror. Some of the Traitor Legions, namely the Word Bearers under the leadership of the Dark Apostle Erebus, think that Abaddon is not fit for the position of Warmaster of Chaos and their cause would be better served if it was lead by a leader with more strategic acumen and less temperamental choler.
Abaddon's troops among the Traitor Legions and the other Forces of Chaos know that he will not accept failure in any form, much like his divine masters, and follow his every command without question. He is the only person to command the obedience of all 9 Traitor Legions during a Black Crusade; no other Chaos Warmaster has ever been able to do the same. Abaddon is the personification of the power of Chaos, the ultimate prodigal son whose return will one day bring the apocalypse to the Imperium of Man.
Vengeful Beyond Reason
Whilst his rival Traitor Legions struggle amongst themselves for the fickle favour of their chosen gods, Abaddon has a purity of purpose that all have come to respect. Under his banners march twisted Chaos Space Marines from every Traitor Legion, Renegade Chapters that have defected from the post-Heresy Imperium, hordes of Chaos Cultists, beast-headed mutants, Abhumans, Space Marines who have given their bodies to possession by daemons, war engines from the Soul Forge and a thousand other freakish strains of anarchist and monster. The denizens of the Eye of Terror have learned over the millennia that those who swear an oath of fealty to the Despoiler would do well not to break it.
When the World Eaters that had promised their aid to Abaddon left his armies to join the fighting upon Skalathrax, the Warmaster abandoned his plans, tracked the Berzerkers down and severed their limbs before cauterising their wounds with a Flamer, leaving them as little more than screaming stumps unworthy of a place at the Blood God's table. When the Emperor's Children that had joined the Black Legion turned upon their masters at Faeruthia he blinded and deafened them to a man, tearing out their tongues and sealing them in inert gel-skin so their sensory deprivation was complete. Upon the crystal planet of Liolonac the Sorcerers of the Thousand Sons denied Abaddon the audience they had promised him, having found a Chaotic relic of unsurpassed value. The Warmaster visited a mutagenic plague upon them that twisted them into bulging repulsive mounds of flesh before lobotomising them and hunting them until death with a pack of warped, daemonic hounds.
Abaddon's vengeance is not limited to his brother Traitors. When a wilderness shrine upon Plutol refused to bow to his authority, Abaddon killed every other human upon the planet before personally visiting the shrine and forcing the priests who maintained it to eat the bodies of those they had once prayed for. Such is the magnitude and thoroughness of each act of revenge that even daemons fear to cross Abaddon. In his singleminded quest to bring the galaxy to heel he earned a new name; the Despoiler, he who would stop at nothing to secure his revenge against the Corpse-Emperor.
Abaddon is possibly the most powerful character in the Warhammer 40,000 universe, other than the Emperor of Mankind or one of the other Dark Gods of the Immaterium. Abaddon is a powerful warrior of immense strength and skill who is armed with a deadly array of both Chaos artefacts and abilities that make him an overpowering foe to face on the battlefield. Abaddon bares the Mark of Chaos Ascendant, which bestows all the benefits of the four other Marks of the Chaos Gods, forever branding him as the greatest Champion of Chaos Undivided. He is also described as a demagogue, able to sway other followers of Chaos to his cause against the Imperium. Abaddon's extraordinary connection to all four of the major Chaos Gods and multiple arcane layers of daemonic protection means that he cannot be killed outright by anything in the purely physical world, even direct fire from a super-heavy tank such as a Baneblade or a Land Raider. Like his predecessor Horus, only the power of the Warp, harnessed by a psyker of immense power and undoubted purity of mind and heart, will be able to slay Abaddon the Despoiler for all time and forever place his soul beyond the capabilities of even the Ruinous Powers to resurrect.
Abaddon is known to bare the following weapons into battle:
- Drach'nyen - In his left hand Abaddon bares the Daemon Sword Drach'nyen. The origins of this fell blade are a mystery. Daemons speak of the blade in fear, calling it the "Thorn in Reality" or the "Shard of Madness." Alive with dark intelligence, Drach'nyen has the power to sunder the material universe with its edge, cutting through matter as a mundane blade moves through smoke. In battle, Drach'nyen has been witnessed to destroy a Space Marine Land Raider and flay the souls from those it struck with a single touch. Even the hardened skin of daemons or armour sealed with the power of the Warp is little proof against its assault, as it drinks in the energy of the Immaterium like water, consuming all in its path utterly. The dark spirit that inhabits this fell weapon can alter the blade's appearance, revealing the skulls and faces of the souls it has devoured.
- Talon of Horus - Upon his right hand Abaddon wears the Talon of Horus, an archaic Lightning Claw with a built-in Combi-bolter, which he took from his fallen Primarch Horus Lupercal after the siege of the Imperial Palace during the Battle of Terra. This legendary weapon is the very same to have slain the Blood Angels' Primarch Sanguinius and mortally wounded the Emperor Himself.
- Armour of Abaddon - Abaddon wears highly customised archaic Catapharactii Pattern Terminator Armour. Abaddon's armour is covered with many archaic devices, runes, and fetishes that he has collected over the millennia during the Long War. The ancient Sons of Horus Terminator Armour Abaddon wears still incorporates a Daemonic Rune gifted to him by the Daemon-Oracle of Asellus Tertius which greatly enhances his protection from mortal weapons.
- Abaddon (also known as Abaddan, Apollyon, Appolyon and Appolion) literally meaning destruction, ruin or perdition — is the Hebrew name of the demon identified as the 'angel' of the bottomless pit, or the abyss, in Christian Bible in the Book of Revelation of St. John; Revelation 9:11.
- Abaddon has also earned the nickname "Failbaddon" by Warhammer 40K fans, due to his many failed Black Crusades.
