In literature, symbolic story or interactive that serves as a disguised representation for meanings other than those indicated on the surface.
The characters in an allegory often have no individual personality, but are embodiments of moral qualities, archetypes, mathematical abstractions, and so on. The allegory is closely related to the parable, fable, and metaphor, differing from them largely in intricacy and length. A great variety of literary and media forms have been used for allegories, both by sapient and transapient writers, philosophers, and artists. John Bunyan's Pilgrim's Progress (_Earth_, pre-industrial age), a prose narrative, is an allegory of humanity's spiritual salvation. Virching Blue Tron's Meta Singularity Hyper via the Small Magellanic Cloud (Lannix Ring Demopolity, early CoEmp period), a multi-immersive interface art-game, is a comment on Inner Sphere galactic civilization.
