Morgan is a very intense and powerful man with a talent for evocation spells, specifically those using Earth magic. He is a stickler for rules and has been a Warden of the White Council for over a century, a job that he takes very seriously. He has an innate distrust of Harry Dresden, which often leads him to conclude that Harry is at fault for certain situations. Morgan's sword is able to cut through magical shields, something which has nearly led to Dresden's wrongful death at least once. He has often gloated when Harry was in trouble, anticipating the opportunity to execute what he sees as justice for the self-defense killing Harry did as a teenager.
