Tzeentch, the Changer of Ways, is the Chaos God of change, fate, sorcery, and manipulation. His daemons and mortal followers are masters of magic and deception, weaving schemes within schemes across centuries. Tzeentch delights in complexity, paradox, and the unravelling of plans — including his own. His realm in the Realm of Chaos is a constantly shifting labyrinth of impossible architecture and mutating reality.

Tzeentch has manipulated the fate of the Old World since the dawn of time, his schemes so complex that even his own daemons cannot comprehend them. The Blue Scribes record every spell ever cast. The Changeling impersonates heroes and villains alike. The Thousand Sons of the north — Chaos Warriors devoted to Tzeentch — have launched countless sorcerous invasions. Every major event in history has, somewhere, a thread that leads back to the Changer of Ways.

Tzeentch's forces are built around magic and mutation. Pink Horrors and Blue Horrors are daemonic infantry that split and multiply when slain. Flamers of Tzeentch project devastating magical fire. Screamers of Tzeentch are flying daemonic manta rays that slash through formations. The Lord of Change — Tzeentch's Greater Daemon — is one of the most powerful sorcerers in existence.

Tzeentch's followers are sorcerers, scholars, and manipulators — those who seek knowledge and power through change and deception. His mortal champions are often mages who have delved too deep into forbidden lore. The Cult of Tzeentch operates in every major city of the Old World, its members unaware of how many layers of manipulation surround them. Nothing is ever as it seems in the service of the Changer of Ways.
