In literature, fantasy is a form of fiction encompassing novels, short stories, role-playing games, and movies. It is typically set in worlds quite different from the Earth and inhabited by users of magic and mythical creatures such as dragons and unicorns. As a genre, fantasy is both associated and contrasted with science fiction and horror fiction. All three genres feature elements of the fantastic, of making radical departures from reality or radical speculations about what reality might be like, or might have been like. "Fantasy" seems reserved for fiction that features magic, brave knights, damsels in distress, mythical beasts, and quests. As such, it has a long and distinguished history, with beginnings in Greek mythology and Roman mythology (famous examples are Homer's Odyssey) and other epics such as Beowulf), and a very strong influence from medieval romance. The legend of King Arthur, with its magic, swordplay, and romance is another clear precursor of contemporary fantasy.
In the 19th and early 20th centuries, much fantasy was published in the same magazines as science fiction (and often written by the same authors). After the great popularity, in the mid-20th century, of J. R. R. Tolkien's The Hobbit and The Lord of the Rings, as well as of C. S. Lewis's Chronicles of Narnia and Ursula K. Le Guin's Earthsea series, fantasy writing saw renewed popularity, often influenced by these seminal works and, like them, borrowing from myth, epic, and medieval romance.
This fiction and its older predecessors in turn gave birth to fantasy role-playing games such as Dungeons & Dragons, which in turn spawned more fiction in the genre. Game companies have published fantasy novels set in their own fictional game universes; the Forgotten Realms and Battletech series are some of the more popular.
Similarly, series of novels based on fantasy films and TV series have found their own niche.
