Tzeentch

Tzeentch, referred to as the Changer of Ways, was a Ruinous Power that skewed towards deception and intrigue, always plotting and manipulating from within the confinement of Chaus. Tzeentch did not plot towards some end (at least none that can be comprehended); he schemes simply to scheme. He is constantly building, even as his devices unravel under their own complexity.

The truth is that Tzeentch's every action is planned with its ultimate goal as his own establishment as the pre-eminent soul of the universe.
