Grimbor is a master craftsman able to create confining devices that didn't fail. He came into contact with a young mutant girl named Charma Drisden when he was hired by the female headmaster of a school she attended on her native planet, Turabeau, to devise a way of negating her powers, which was an aura that made men love and protect her and women hate and fight her.
