fictional location

Fictional locations are places that exist only in fiction and not in reality, such as the Negaverse, Planet X, or Skyrim. Writers may create and describe such places to serve as backdrop for their fictional works. Fictional locations are also created for use as settings in role-playing games such as Dungeons and Dragons. They may also be used for technical reasons in actual reality for use in the development of specifications, such as the fictional country of Bookland, which is used to allow EAN "country" codes 978 and 979 to be used for ISBN numbers assigned to books, and code 977 to be assigned for use for ISSN numbers on magazines and other periodicals.
