List of fictional universes
This is a list of fictional universes, organized by genre and by sub-genre. The term universe can be misleading, since some of them are supposed to occur in our own world, but in a fictional future (science fiction) or past (Hyborian Age) timeline. Because one author's universe may produce stories in different genres, it may be listed in more than one place.

They can be found in a variety of fantasy genres, e.g. high fantasy, heroic fantasy, sword and sorcery, etc.
