A fantasy world is a fictional universe created in fiction media, such as literature, film or games. Typical fantasy worlds involve magic or magical abilities, nonexistent technology and sometimes, either an historical or futuristic theme. Some worlds may be a parallel world tenuously connected to Earth via magical portals or items; a fictional Earth set in the remote past or future; or an entirely independent world set in another universe. Many fantasy worlds draw heavily on real world history, geography and sociology, and also on mythology and folklore.
