Demonic Sorcerer

The Sorcerer was a demon that made a deal with the former Mercury demon Drake dè Mon. Drake would be made human and given a soul, but the catch was that he'd give up his immortality and he would die in one year. Also if Drake used his powers in an offensive manner, they would be forfeit to the Sorcerer. In the episode Carpe Demon, Drake accidentally loses his powers when under the belief that he was Robin Hood protecting Phoebe, who he believed was Maid Marian. After using his powers, the Sorcerer appears and sends him to limbo to be tortured in eternal flames, as Drake's powers were stripped because of the broken deal. With the help of Ms. Donovan, the librarian from Magic School, the Charmed Ones were able to vanquish the Sorcerer with a spell and return Drake with his poweres restored.
