Ahzek Ahriman – Arch-Sorcerer of the Thousand Sons

Few figures in the history of the Prosperine legion are as influential—or as controversial—as Ahzek Ahriman. Once the Chief Librarian of the Thousand Sons, Ahriman was among the most brilliant psykers of the Imperium, driven by an obsession with knowledge and mastery of the warp. In an attempt to save his legion from the mutations that plagued it, Ahriman cast the infamous Rubric, a spell that halted the corruption but at a terrible cost. Most of the legion’s warriors were reduced to dust within their armour, becoming the silent Rubric warriors that now march at the command of surviving sorcerers. Despite exile and centuries of wandering, Ahriman remains one of the most powerful psykers in existence. His endless pursuit of hidden lore and forbidden knowledge continues to shape the fate of the Thousand Sons and the wider galaxy. On the tabletop, Ahriman naturally stands as a central sorcerous commander within a Thousand Sons army. Surrounded by Rubric warriors and arcane constructs, he embodies the legion’s defining trait: a relentless, dangerous quest for knowledge that borders on the impossible.
