A term coined by Ron Edwards on The Forge for 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. Also called "inverse metaplot."
