Tzeentch is the Changer of Ways and the Architect of Fate. Feeding upon the ambitions, hopes and desires for change that reside in all mortals, he twists and weaves the threads of fate that connect all things in a galaxy-spanning game of intrigue, politics and subterfuge.

- The Great Sorcerer: Tzeentch is the undisputed master of magic and sorcery in the universe. To him, magic is the very embodiment of change, a result of a psyker’s desire to enforce their will upon the universe itself. As such, he grants his chosen champions with untold sorcerous powers.
