They are pretty much all OCs, just with horns, claws, and a tail all of your own choice. You decide how they responded to being caged, where/how they were caged, and how they go about their life afterwards. If they were in the band, you decide what their relationship was like with the other ghouls and with Papa 1 or the crew and such!

With non-band ghouls, backstory and everything is up to your imagination. They could even come out of their trauma feral! The only guideline is that if an era one was with others while caged, they no longer have their full horns because they would have been broken off for safety reasons (as if ghouls couldn’t kill each other without them or something, heh). There were also humans who were against the locking up of the ghouls who got thrown into the mix of pissed off ghouls, so you could play a really resourceful human who somehow survived being locked away with angry feral creatures for years and years!

There’s also a non-band ghoul available that’s in Fire’s backstory that I don’t have the time to play, but is totally an option for someone else. She’s a ghoul that was in the basement with him and they had a silent, mutually beneficial alliance that likely contributed to them both surviving as Fire did/she has still.
