There is one dude who shows up at the Chillout Lounge that my con roomies turn their room into who has claimed to be (a) an vampire and (b) Lucifer. He is pretty enough to be either - a skinny boy with an indeterminate accent and long blonde hair, and an easy social air.
Whatever truth there is to his stories, I can’t say. But identifying as those things? That’s a warning I think I’ll heed.
