There's no place like home, even for those of supernatural origin. And for some, their home is quite different from ours. It could be anything from a dark forest, to hidden caves, or maybe even an entirely different plane of existence. The one thing they have in common is their significance of being the place where these fantastic beings were born and raised.
Places like this usually tend to be a Fantasy Kitchen Sink. The location itself is frequently a Deserted Island, Void Between the Worlds, and/or an Eldritch Location. Not to mention there's always the chance that the place itself is another monster. May tie into Villainous Badland, Heroic Arcadia.
- Bleach has Hueco Mundo, the home of the Hollows.
- In Fairy Tail, the island of Galuna is eventually revealed to be home of the Demon race. However, it's also a case of Dark Is Not Evil.

- Skull Island of the King Kong movies, especially as of the newest film.
- The MonsterVerse has the Hollow Earth. Introduced in Kong: Skull Island as where the Skull Crawlers came from, Kong and a Monarch team visit it in Godzilla vs. Kong and find that it is full of all sorts of Kaiju. Kong's species had a rudimentary civilization in the Hollow Earth and once fought a Great Offscreen War against Godzilla's species there.
- The Nevernever in The Dresden Files is supposed to be this.
- Debatable. Home to the Faeries and some of the weaker demonic types, yes (the really nasty demonic types are "outsiders," and live... entirely elsewhere), but that seems to be about it. However, pretty much any supernatural creature (vampires, ghosts, and wizards of sufficient strength) can enter the Nevernever.
- Starship Troopers: Klendathu, home of the arachnid race.
- Can anyone say "The Nightside" from Tales Of The Nightside by Simon R. Green? Not exactly where the monsters come from, but all monsters eventually end up there.

When your party eventually gets sent there, you find out that it actually is, but not to the greatly exaggerated extent that the Cocoon government has misled everybody into believing, where the average Cocoon citizen is deathly afraid of anything that is even remotely connected to Gran Pulse.
- In Dragon Quest VIII the monsters are basically everywhere. However, there's a particular village named Trian Gully where monsters reside along with elves and humans, making it something of a subversion.

- In the Langrisser series the majority of demons dwell in the land of Velzeria. It's also the only known locale in the setting in which demons and humans live side by side. How good or evil they are varies between games and individual routes. In the dark route endings of the first game's remake The Hero ascends the Velzerian throne and falls firmly on the good side. Leading to other nations finally considering the possibility of peace with demonkind. Sadly for the world this is very much not canon.
