He is one of the oldest skeksis and one of the Empire’s founders. He created a cult worshiping the dark powers of the universe (the Darkening which is present at every planet with a Crystal). His way to cheat death is to completely replace his flesh with metal and machine. His acolytes go through this process slowly with dedication. The worship of the Void is a way too, because he hopes secretly to gain the good will of the darkness to spare him. He claims the Void is speaking to him. He is a bit crazy as he talks. Despite his dark look he acts funny and light-hearted. The skeksis of the Empire fear him and his acolytes.
