Ahriman

For ten thousand years, the seeker of arcane truths known as Ahriman has roamed the galaxy in a quest to acquire every artefact, every tome and every scroll that harbours eldritch powers. Worlds burn in his shadow as he plucks these treasures from their owners by any means necessary. Resistance is the last error his enemies can make – Tzeentchian magic reshapes reality around them, a pass of the Black Staff twisting their bodies unnaturally until nothing remains but bubbling flesh. Ahriman, lord of a broken Legion; his determination is such that destiny itself bends to his whim.
