Sent by Axel Mortmain, this demon took the form of Richard Gray and slept with his wife, Elizabeth. Because Elizabeth was unmarked and through Mortmain's intervention by protecting her with the angel Ithuriel in her clockwork pendant, their offspring survived birth, resulting in a new kind of being: Tessa, a half-demon, half-Shadowhunter.
- The identity of this demon may be revealed in The Last Hours and will be hinted at in Ghosts of the Shadow Market. There may be a major revelation regarding him in Every Exquisite Thing.
