Black Spire III: A Twisted King
The Lich is an old, powerful necromancer. He was once the master of Ofec, the shifty necromancer, and Ironcrow the sorcerer. He never revealed his real name; Ofec might perhaps have known it, but he is dead and buried beneath tons of rubble.
The dying old necromancer used the power of The Chief-Stone to transform himself into a lich. His current whereabouts are unknown.
