Is he a standalone real manifestation of nightmare, or does he use his victims' minds to assume shape? (sort of like how the Sorting Hat in Harry Potter works). In the first case, if he were inside Wulfric, upon inspecting himself Wulfric would identify two beings. In the second, only one.Ah, forgot to mention. Wulfric is an alchemical vampire. He is not undead, but fully alive. Has a heartbeat, requires normal food (not only dying emotions), can drown/choke, can have children, etc. And, since he is fangless, he can't bite humans into vampiredom.

He is kind of both, he is at his core a single fear, just one bad dream, but he draws the fears and nightmares out of others and uses them as a sort of fuel so he can do the things he do. I don't want to get into it too much as it will reveal the background that I wanted to slowly unravel through out the RP.
