Intro. The vagrant of the paradise. A prophet and advisor who made his entry into Arthurian LegendsWP as the court magus, he would at times guide, at times torment, and at times help King Arthur as a king so that she could overcome many enemies and hardships. Still, though he is a wise man, he is fundamentally inhuman, because he was born of mixed blood from the union of an incubus and a human. With illusions as his forte, he can transform into various shapes——there was a case where he had changed into the shape of a beast whose insides are not human——and his true form is not certain.
