Crimson King

The Crimson King, known to some as Los' or Ram Abbalah, is a fictional character created by Stephen King and the main antagonist of King's eight-volume Dark Tower series, as well as the novels Insomnia (1994) and Black House (2001). Described as "Gan's crazy side", the Crimson King is the ultimate ruler of the Red, and the archetypal embodiment of evil in Stephen King's fictional multiverse. His goal is to topple the Dark Tower which serves as the linchpin of time and space, destroying the multitude of universes which revolve around it so that he can rule in the primordial chaos which follows.
