I would hope the villains are restricted to Magic users/Gods (Queen, Chenabog, Maleficent, Ursula, Jafar, Hades, Dr. Faciller) who have an easy reason they can exist together (Magic.) That said, if you are going with the banished from MK theme the Stepmother/Stepsisters could fit as well. Gaeston has his tavern in MK so he shouldn’t also be in villain land. Because it’s too good of a concept, I would also be willing to overlook a Cruella “owned” themed table service restaurant because it would be awesome.
