Abraham is a wizard, specifically the one responsible for creating the Dewitchery Diamond. He has sworn to kill anyone or anything created by the diamond's curse-breaking powers. To facilitate this, he has put a spell on himself which transmogrifies him into stone unless he is attempting to "reap that which he has sown", i.e., killing the spawn of the Diamond. After being defeated by Nanase's angel form, he changes the spell to awaken him to "atone for his sins". __TOC__
