Labyrinths (synonyms: mazes; example toponyms: The Mistywork Labyrinth) are elaborate mazes that contain a tangle of passageways, dead ends, and intersections making them difficult to navigate. They may have been put in place to protect a treasure, as a type of prison, or as an amusing means of torment. Labyrinths may contain monsters, traps, riddles & clues, as well as walls and passages that rearrange themselves. In game-oriented worlds, labyrinths may be part of a dungeon. In general, labyrinths are constructed locations, but natural features may also resemble labyrinths.

Labyrinths are often depicted as being built of stone, but other types are also common and possible. Labyrinths may be an endless series of hotel hallways or a catacombs. Hedge mazes and corn mazes are a type of labyrinth. When designing labyrinths for fictional worlds, consider the purpose for which they were built and the type of person, persons, gods, alien, or other that designed this place.

Labyrinths originally come from Greek myth, and were built by the genius inventor, Daedalus, to house a minotaur.
