An overwhelming majority of fiction is set on or features the Earth. This also holds true of science fiction, despite perceptions to the contrary. Counterfactual depictions of the shape of the Earth, be it flat or hollow, occasionally are featured. A personified, living Earth appears in a handful of works. In works set in the far future, Earth can be a center of space-faring human civilization, or just one of many inhabited planets of a galactic empire, and sometimes destroyed by ecological disaster or nuclear war or otherwise forgotten or lost.
