-His name is Felix for irony's sake
-He's been around since pretty much the romans and the greeks have been kickin' it, he's immortal.
-He feeds off of other people's creativity. Not necessarily art or dance or music or anything -- it can be abstract, like, he could become obsessed with a chef at some point, or an architect, or a mechanic, etc
-He takes in people talent or no--and basically offers people struggling in some way that want to be good at what they do of famous, 'hey I can give you the moon' like a faustian pact sort of deal
-After x amount of time (dependent on how bad they want it) he collects them and they either fall from artistic grace or go crazy because he's no longer around or both.
-He's around for the greats, but always in the bg. There's probably crazy theories on reddit about him that are all somehow debunked
-When he finds people who are just good at what they do creatively naturally he like... latches on and becomes obsessed even if they haven't entered a contract with him. Stuff that other people have naturally is just such a fascinating concept to him. It can be a harmless crush to a straight up obsession depending.
-He can't actually create anything worth it/good because he fell in love with a mortal when he was young, the mortal died and left Felix unable to create
-Felix now wanders the world looking for the reincarnation of his lost love, channeling artistic energy to keep himself going in his search
