A fantasy world is a kind of invented world, part of a imagined life used in fantasy novels and games. Typical worlds involve magic or magical abilities and a medieval theme. A few worlds may be a parallel world tenuously connected to Earth via mysterious portals or items; imaginary Earth set in the remote past or future; or an totally independant world set in a different universe.
Many fantasy worlds describe heavily on real world history, geography and sociology, and also on folklore.
The setting of a fantasy work is often of great importance to the plot and characters of the story. The setting itself can be imperiled by the evil of the story, suffer thinning, and be restored by the transformation the story brings about.Stories that use the setting as merely a backdrop for the story can be criticized for their failure to use it fully.
Even when the land itself is not in danger, it is often used symbolically, for thematic purposes, and to underscore moodes.
Early fantasy worlds appeared as fantasy lands, part of the same planet but separated by geographical barriers. Oz, though a fantasy world in every way, is described as part of this world.Although peasants who seldom if ever traveled far from their villages could not conclusively say that it was impossible that, for example, an ogre could live a day's travel away, distant continents were soon necessary for such fantastic speculation to be plausible, and finally, further exploration rendered such fantasy lands implausible. Even within the span of decades, Oz, which had been set in a desert in the United States,was relocated into the Pacific Ocean.
Dream frames were also once common for encasing the fantasy world with an explanation of its marvels. Such a dream frame was added to the story of The Wonderful Wizard of Oz for the movie version; in the book, Oz is clearly defined as an actual place.These dream-settings have been criticized, and are far less frequent today.
