Definition
A Book Bible is a structured, persistent reference document that captures everything about a book that needs to stay consistent: characters, world rules, timeline, voice ledgers, tropes, heat level, and any author-specified facts. In BookWriter, the bible is loaded into context for every chapter draft and enforced by the consistency pass.
What lives inside the Book Bible
The bible is structured by category so the model can look up the relevant section without re-deriving facts.
- Cast sheet — name, age, physical description, occupation, relationships, voice ledger entry per character.
- World rules — magic system, technology limits, geography, social structure.
- Timeline — anchor events (real or invented) the book cannot drift past.
- Tropes and beats — the trope choices and emotional structure you committed to.
- Heat level and tone — set once, enforced everywhere.
- Author-specified facts — the names, details, or specific phrases you want preserved verbatim.
Why it matters
Without a persistent bible, a long-form AI draft drifts. Names change spelling, eye colors shift, town names flip, prior events get contradicted. By chapter twelve, the book contradicts itself in ways the author did not authorize.
A bible turns the model from a stateless prose generator into an accountable author. Each chapter draft must agree with the bible. The consistency pass scans each draft against the bible and flags drift before the chapter persists.
How it carries to sequels
When a book finishes, its bible can fork into a Series Bible for sequels. Names, world rules, character arcs, and timeline carry forward automatically. Sequel Writer mode picks up where book one left off.
