After posting the previous image, I felt inspired to finish the ref sheet I had started for him.

Age Unknown. No one in the Dream World remembers a time without him.
Sex Technically none. He has no reproductive organs, but he prefers to use male pronouns... he would make an ugly girl anyways.
Personality Narcissistic, flippant, and often fairly childish. He can have a very whimsical nature when he is in a good mood, but his temper is venomous. He despises authority and considers himself above the rules.

His eyes were removed as punishment for an old crime. He had been stealing faces from humans (a spell which requires eyes) and using their forms to wreak havoc in the mortal realm. He still has the ability to partially reshape his form to be somewhat human, but has to hide his true nature (should anyone see that he's not human he will return to being in the shape of a fox).
