Although most mummies are created merely as guardians and remain loyal to their charge until their destruction, certain powerful mummies have much more free will. The majority are at least 10th-level clerics, and are often kings or pharaohs who have called upon dark gods or sinister necromancers to bind their souls to their bodies after death-usually as a means to extend their rule beyond the grave, but at times simply to escape what they fear will be an eternity of torment in their own afterlife.
