"Not all look as human as I—claws and fangs are common, as are tails. Some are associated with certain animals, such as snake demons or wolf demons. And we have fire and ice clans as well. But my line is the Heavenly Demons—those descended from heavenly beings, who were banished and became demons instead. I am the last remaining." Except Crowley.
