That`s a side effect to using dark magic. That`s where sorcerers like me get our powers. By practicing dark magic, you are inviting these spirits to interact with your body in exchange for harnessing their powers. They`re mischievous little fellows, and not all spell casters can handle them. Some mages turn into vegetables. Sometimes even ACTUAL vegetables. Or they just die, but I`m sure everything will be fine.
