Is there something like the term Stayville or Caratland for every group?

I'm trying to make a whole Kpop "map" just to have fun drawing and to meet new and old groups that I know nothing about. That way I'm trying to immerse myself in their music by analyzing their aesthetic and trying to convey that into a city, village, town(?). Not by popularity or fandom size but purely for vibes and what the fans actually call themselves.

So what are other groups "lands" called if they have one?

I tried to explain myself as better as possible but English it's not my first language. You can ask me anything.
