The Crimson King is the main antagonist of The Dark Tower Series. He is the orchestrator of the chaos and decay in the Keystone World and much of that in all the other worlds connected by the Dark Tower. His ultimate goal is to tear down the Tower, bring about Discordia, and re-make the world in his image. Eddie Dean sees the Crimson King as being equivalent to "Satan" in the religions of his own world. However, this is a simplification of the true origin of "Le Roi Russe".
