Ahriman from Thousand Sons legion…
“Sorcerer. Betrayer. Deliverer. Ahriman, former chief librarian of the Thousand Sons, is one of the most-skilled (indeed, perhaps the most-accomplished) sorcerers of the 41st millennium. When the mutating effects of Chaos became plain amongst the Thousand Sons legion, Ahriman cast the terrible rubric that reduced almost all his brothers to dust and deathless spirit. So did Ahriman earn his exile from the Planet of the Sorcerers. Now he wanders the galaxy, cursed to an obsessive quest for knowledge and power. This warped crusade has led Ahriman to cross swords with some of the mightiest heroes in the galaxy, and has brought him into constant conflict with any who hold arcane knowledge – most notably the Eldar Harlequins and the Inquisitors of the Ordo Malleus.”
