Byron Befuddle

Byron Befuddle was the owner and builder of Befuddle Manor, imprisoned there when Queen Morbidia took the place over. Some of her magic brought his shadow to life as a Shadow Demon under his control. He was able to use it to go out and steal the Chest of Demons, and he helped the gang foil her plans.
