Xaphan

Xaphan is a demon, one of the first Fallen who was around even before Cain was turned into a vampire. After possessing a woman and causing her to kill herself by throwing herself in front of Blake's car, Xaphan possessed Blake for six months before Blake was found by the vampire Elise. With the help of master vampire Mencheres, Elise brought Blake to the salt flats of Utah and successfully drove Xaphan out of Blake. After this, Xaphan presumably died or was rendered powerless.
