Direct answer

A story bible is the single document holding every load-bearing fact about a fictional world — characters, places, dates, magic rules, technology, glossary. Authors maintain it during drafting; editors and co-authors reference it for continuity. Series writers cannot work without one. The bible typically grows to 10-40 pages by the end of a novel.

Chapter i·Why it matters

Continuity errors are the most-cited reader complaint on Goodreads. A story bible eliminates most of them by giving every "wait, what was her last name?" question a definitive answer. The bible is the first file editors ask for and the last file series writers stop updating.

Chapter ii·What to include

  • Characters: name, age, role, physical description, voice notes.
  • Places: spellings, descriptions, distances, maps.
  • Timeline: in-story dates, character ages at each scene.
  • Rules of the world: magic, technology, social structures, religion.
  • Glossary: made-up words with pronunciation and definition.
  • A "voice anchor" excerpt representing the book’s tone.

Chapter iii·Example

A fantasy author’s story bible at the end of her 95,000-word draft: 22 pages covering 12 characters, 18 places, a 200-year timeline, three magic systems, and a 60-entry glossary. She updates it scene-by-scene during drafting and the bible saves her from a major continuity error in her revision pass.
