There’s whole ficverses that usually get built around a popular enough fanfic.
That’s even more usual when the fic in question introduces a unique enough setting: e.g. most relevant to LessWrong would be The Optimalverse, the ficverse built around Friendship is Optimal, but I imagine the ficverse built in the setting of “Fallout: Equestria” to be the biggest one by far.
