"And what are the achievements of your fragile Imperium? It is a corpse rotting slowly from within while maggots writhe in its belly. It was built with the toil of heroes and giants, and now it is inhabited by frightened weaklings to whom the glories of those times are half-forgotten legends. I have forgotten nothing, and my wisdom has expanded far beyond mere mortal frailties."
~ -Ahriman of the Thousand Sons.

Ahzek Ahriman, also known as Sorcerer of the Red Cyclops and Ahriman of the Thousand Sons, is a powerful Chaos Space Marine sorcerer belonging to the Thousand Sons legion. He roams the galaxy commanding a warband, raiding and plundering bastions of information.

Born on Terra and recruited into the Thousand Sons, Ahriman rose through the ranks of his legion to become their Chief Librarian and preeminent master of one of their psychic disciplines: precognition. Surviving the various battles of the Great Crusade, Ahriman found himself at the centre of the events that would lead to the fall of the Thousand Sons and their collective descent into the clutches of Tzeentch, Chaos God of sorcery and change, during the Horus Heresy. His actions after the Heresy - particularly creating and enacting the great spell that bears his name, the Ruric or Ahriman - would result in his eventual banishment from the Legion he had spent most of his existence trying to safeguard. His current status is that of wanderer, apparently fated to quest for something never achievable; understanding of the nature of Tzeentch itself.

Despite the nature of his doom, Ahriman has embraced his quest totally, and no bastion of knowledge in the entire galaxy can be considered safe from his rapacious intellect.


Ahzek Ahriman was born on Terra, among the wealthy tribes of the Achaemenid Empire whose kings had allied with the Emperor during the Unification Wars. Because of this alliance, Ahriman's tribes were largely spared the horrors of the atomic wars and proto-Astartes invasions of the Unification period. Following the Emperor's victory and Terra's alliance with Mars, Ahriman and his twin brother Ohrmuzd were selected to be inducted into the ranks of the Astartes. Ahriman fought alongside the Emperor and the other legions at the start of the Great Crusade, but five years into the expedition the Thousand Sons legion began manifesting psychic abilities, and with the manifestations began the flesh-changes. Terrible and warping mutations gripped the entire legion, countless warriors succumbed and fell to the changes. Over time the problem got so severe that many voices throughout the Imperium even began suggesting that the legion be disbanded. Ahriman even lost his own twin brother Ohrmuzd to the effects. Eventually the crusade reached Prospero, and the discovery of Magnus couldn't come soon enough. The discovery of their sire marked a turning point in the fortunes of the Thousand Sons legion, Magnus was able to seemingly cure the warping effects and the devastation they had upon his legion. Magnus however sacrificed much in order to achieve this, he lost his eye in the effort, which was implied to have involved bargains with Chaos Powers.

Before the events of the Horus Heresy, Ahriman, risen to the positions of Chief Librarian of the legion and leader of it's most powerful cult, the Corvidae, had shared his Primarch's obsession with arcane mysteries and by the beginning of the Heresy had come to be keeper of the now mythical Book of Magnus, a tome of incalculable sorcerous power.

It may have been knowledge gleaned from that very tome with which Ahriman conjured his now infamous master spell. The result of the so called 'Rubric of Ahriman', while imperfect, is said to have satisfied Ahriman in its consequence. In essence, it turned all the warriors without psychic abilities into mindless automata, and greatly amplified the abilities of all who had more then a spark. Ahriman was a veteran Thousand Son from before the coming of Magnus the Red, and Ahriman's revulsion at the corruption of the Legion was so great that even the terrible price of reversing it was not too high. Ahriman attempted the spell at first, alone. He was unsuccessful, and later it required a large Cabal of Sorcerers to assist him, who were only motivated to do so upon Magnus' elevation to Daemon Prince. The last vestiges of humanity were purged from the Thousand Sons, and few desired the resulting spawndom.

Magnus was not of like mind, however. So great was his wrath when the cabal was discovered that the Primarch threatened to obliterate them utterly, but the very patron who had worked the mutations upon them in the first place was said to have intervened. Who can say what the most enigmatic and capricious of entities intended? In any event, the Daemon Prince stayed his hand, instead banishing Ahriman from the Planet of Sorcerers and condemning him to wander the Eye of Terror and beyond in a hopeless quest to understand the Chaos god Tzeentch.

For his part, Ahriman refuses to acknowledge Chaos as his master. Across the ensuing millennia he has become a scourge, raiding ancient museums, librarium, scholaria and reclusia, places of learning, religion and contemplative thought. He seeks to acquire artifacts, data, or even persons he believes can lead him to mastery over the way of the sorcerer. He fosters cults on dozens of worlds at a time, providing cult magi with sorcerous power until such time as they have acquired some antiquarian trinket or satisfied another of Ahriman demands before turning the wrath of his warband upon them. It is rumoured that Ahriman has of late turned his relentless predation upon the Eldar, determined in his belief that the lost knowledge he seeks can be found in that darkest of halls of enlightenment, the vast repository of arcana referred to in whispers as the Black Library of Chaos.

Current Whereabouts and Dealings

During Abaddon's 13th Black Crusade Ahriman was able to gain access to the Webway using the captured Inquisitor Czevak and a long forgotten webway portal on Etiamnum III. It is rumoured that if he obtains entry into the Black Library, he could use the information inside to become a new and powerful Chaos God.

Despite summoning a 'Leviathan', a giant flying warp beast and Ahriman bringing horrendous casualties on both sides of the conflict; Ahriman was ejected from the Webway his goal unattained, Inquisitor Czevak captured by harlequins and believed held in the webway, the webway Gate he used was sealed, never to be opened again. The final results of the Campaign state that his 'star is on the rise' with Magnus once again, mostly due to the great chaos caused by his battles in the Webway, prowness in capturing Inquistor Czevak, and ability to come close to entering the Black Library.

Weapons and Abilities

Ahriman is a true master of sorcery and one of the most powerful psykers in the galaxy, his knowledge of the dark arts is rivalled only by the greater daemons of his patron. In addition to the multitude of Chaos Psychic Powers he can call upon, he is armed with The Black Staff of Ahriman; an ornate Force weapon which provides a potent focus for his psychic energy. He also carries an enchanted bolt pistol which fires powerful Inferno bolts similar to the weapons of his Rubric Marines.
