A fantasy world or fictional world is a world created for fictional media, such as literature, film or games. Typical fantasy worlds feature magical abilities. Some worlds may be a parallel world connected to Earth via magical portals or items ; an imaginary universe hidden within ours ; a fictional Earth set in the remote past or future ; an alternative version of our History ; or an entirely independent world set in another part of the universe.
