Morticus, sent the Purple Cloaks on their final mission, which happened to be kill Veleno and retrieve a book from her lair. They were successful in slaying Veleno, but she was able to kill a few members of the Purple Cloaks. In an attempt to rescue his friends, Norman Proch read the book that was found in the lair. It drove him to evil madness as he attacked the remaining members of the Purple Cloaks. When they awoke they found that Norman was gone, with the book and the corpse of Veleno. Her body has never been seen again and Norman can't seem to recall what happened to her body after he was cured.
