Dunno the details, I think we agreed he's some kind of dove. Probably angelic looking, and looked human most of his life. Probably doesn't learn that he's a goetia let alone a demon until he's in his late teens. Has incredible talent with magic since he's a cambion like Merlin.
Thought that brings up another question, is Nymo baptized? Merlin was, which is why he isn't wicked. Maybe that's why Nymo is slightly angelic, because he was raised christian and cleansed of demonic taint.
