Fantasy Literature refers to a genre of fiction that uses magic and other supernatural elements as a primary plot element, theme, or setting. It often involves the creation of a vast, complex, imaginary universe, filled with detailed maps and systems of magic, where fantastical creatures and magical beings exist. This literary genre can be distinguished from science fiction and horror by the expectation that it steers clear of scientific and macabre themes, respectively, though there is a great deal of overlap among the three, all of which are subgenres of speculative fiction.
