Shared universe

A Shared universe is a literary technique in which several different authors share settings and characters which appear in their respective works of fiction, often referring to events taking place in the other writers' stories. It can also be called a "shared setting." It can be a metafictional device. Shared fictional universes tend to appear more frequently in fantasy and science fiction than in other genres.
