Without a doubt, the only sanctuary in the apocalypse. Huh? Why aren't her shop staff robots? Why is one a major villain from a fantasy world? And another a wronged legitimate daughter from ancient times? Or a betrayed leader from a beastfolk world? Don't tell her every one of her employees has a secret identity! Now that they're all on the same team, she's got to help them get even!
