Mini Bio from the Manual:
A cold-blooded human serving the Fairy Kingdom of Ringford, Oswald is know as the Shadow Knight, and is feared for having slain a baby dragon. He was abandoned as a baby, but was taken in by Melvin, nephew to the Fairy Queen Elfaria. He lives only to serve his adopted father, regardless of the consequences. As a result of being treated like a slave for so long, he places little value on his own life.
