Tzeentch, because he rules all the Warp related thing, like Psykers and almost everything in the universe
all the Chaos gods are the same, if the Warp actually did consume the Materium, then they would cease to exist :/
maybe... but Nurgle... It is the forfeiture of all .... in the long term... Slaanesh is the best in the immediate ecstasy
Tzeentch has everyone, including the other Ruinous Powers, marching to his plan. The only ultimate power of Chaos is the one who truly does not want the power. It is said that his plans subvert the his others, because controlling the universe would be an end to Chaos. AND WHO WANTS THAT?
hat Tzeentch built nurgle destroyed, the opposite is also true. Khorne and Slaanesh play during this time. the indivisiblechaos is eternal ...
Indeed I'm torn between all 4, they are all in a sense powerful Chaos Gods. I would worship them equally rather then devote to just one. As the blessings of all 4 Chaos Gods are more powerful then the favor of one Chaos God.
