|The Big Model|
A Technique of preparation and play using a canonical setting and storyline, known to all participants, in which the events of play create a "hidden" storyline to enrich and reinforce the primary one, which is treated as a creative constraint. Term coined by Ron Edwards; also sometimes called "inverse metaplot." See Metaplots, railroading, and settings (Glossary terms or Forge article?) and Open/closed setting (Pyron's woes take 165).
