Story bible
The reference document centralizing a work's entire universe: characters, places, timeline, world rules.
The story bible (a term inherited from television) is a long-haul work's reference document: character and place sheets, event timeline, world rules (magic, technology, institutions), planned arcs, decisions made. It's the project's external memory — indispensable once the universe exceeds what one head can hold: series, sagas, ensemble novels, imaginary worlds.
Its function is double: guaranteeing consistency (the distance between two cities doesn't change between volumes) and enabling collaboration or resumption after interruption. The bible isn't the worldbuilding itself but its land registry: it invents nothing, it records — and everything in it stays out of the manuscript, available without ever cluttering the story.
Example
Volume 3, chapter 7: how many years between the Wall's fall and the hero's birth? The bible answers in ten seconds.
