What Is a Story Bible? What to Include, With a Template

A story bible is a single reference document that records the facts of your fictional world: who your characters are, where and when the story happens, what has already occurred, and how the prose should sound. You check it while you write so that book three agrees with book one, and so that chapter twenty agrees with chapter two.

Writers' rooms on television series popularised the idea. Novelists, especially those writing series, now rely on it for the same reason: memory is unreliable, and readers notice when a character's eyes change colour.

What goes into a story bible

Most story bibles cover four areas. You can add more, but these four catch most continuity problems.

Characters

Every named character gets an entry. Main characters get the most detail, and minor characters get at least a few lines, because minor characters are where mistakes hide. The barman you named in chapter four and forgot about will come back in book two with a different name if you don't write him down.

A useful character entry records:

• Fixed physical facts: age (or birth date), height, eye and hair colour, scars, voice, handedness.
• Background: family, hometown, job, education, key past events.
• Relationships: who they know, how they met, what they call each other.
• Speech habits: pet phrases, words they would never use, accent, formality.
• What they know and when they learned it: this matters more than most writers expect. A character can't act on a secret they won't discover until chapter fifteen.
• Arc notes: where they start, where they end, and what has changed by the close of each book.

Example: "Mara Okafor. 34 in Book 1. Left-handed. Grey eyes. Calls her brother 'Dee', never 'Desmond'. Doesn't know her father is alive until Book 2, ch. 11."

Setting

Setting entries describe places, and in speculative fiction they also cover the rules of the world.

• Locations: towns, buildings, rooms. Note layout and distances. If the bakery is two streets from the harbour, it can't be a twenty-minute walk later.
• Geography and travel times: how long it takes to ride, drive or sail between places.
• Culture: customs, holidays, religion, food, money, laws.
• World rules: magic systems, technology limits, political structures. Write down what is impossible as well as what is possible.
• Names and spellings: a glossary of invented words, place names and titles, with capitalisation.

Timeline

The timeline puts events in order and attaches dates or relative times to them. It covers the backstory before page one, the events of each book, and the gaps between books.

Record:

• Birth years and ages, so characters age correctly across a series.
• When each major event happens, by chapter and by in-world date.
• Seasons, weather and moon phases if you mention them.
• Travel and recovery times. A broken leg in March shouldn't be healed by April.

Even a simple list in the form "Day 1, morning: Mara arrives at the harbour (ch. 1)" will save you hours of rereading later.

Style rules

Style rules keep the voice consistent, which matters most if your books come out a year apart or if more than one person works on them.

• Point of view and tense: first person past, close third present, and so on, with rules for when POV can switch.
• Narrator voice: formal or casual, sentence rhythm, how much interior thought.
• Spelling and formatting: UK or US spelling, how you style dialogue tags, numbers, italics for thoughts or foreign words.
• Content limits: how much swearing, violence or explicit content the series allows.
• Words to avoid: anachronisms in historical fiction, modern slang in a fantasy world, or phrases you overuse.

Why series writers keep a story bible

A standalone novel is hard enough to keep straight. A series multiplies the problem. You might write five books over several years, and you won't remember what you decided about a side character's sister in book one when you're drafting book four.

Series writers keep a story bible for several practical reasons:

• Readers reread. Series fans often binge the whole set before a new release, so inconsistencies between books become obvious.
• Time passes. The gap between drafting book one and book three can be long. A bible holds the decisions you've forgotten.
• Other people get involved. Editors, proofreaders, cover designers and audiobook narrators all benefit from a reference. A narrator needs to know how to pronounce your invented names.
• Planning gets easier. When you outline the next book, the bible tells you which threads are still open and which characters are available.
• Spin-offs and bonus content. If you write a prequel novella or a newsletter short story, the bible keeps it in line with canon.

If you're still planning book one, our guide on how to outline a novel pairs well with starting a bible at the same time.

How a story bible prevents continuity errors

Continuity errors happen when the text contradicts itself. The bible prevents them by giving you one place to check a fact before you write it, and one place to record a new fact as soon as you invent it.

Here are the most common errors and the part of the bible that stops each one:

Continuity error	Example	Bible section that prevents it
Changing physical details	Blue eyes in chapter 2, brown in chapter 19	Character entry: fixed physical facts
Name or spelling drift	"Kaelen" becomes "Kaylen"	Setting: glossary of names
Impossible timing	A three-day ride done overnight	Setting: travel times; Timeline
Wrong ages	A character is 12 in book 1 and 14 in book 2, set one year later	Timeline: birth years
Knowledge errors	A character mentions a secret before learning it	Character entry: what they know and when
Broken world rules	Magic does something you said it couldn't	Setting: world rules and limits
Voice drift	Narrator turns chatty halfway through	Style rules: narrator voice
Dead characters returning	A killed-off guard reappears	Character entry: status (alive/dead, with chapter)

The habit matters more than the format. Check before you write a fact, and record it after you invent one. A bible you don't update is worse than none, because it gives you false confidence.

How a story bible differs from an outline or a series bible

These terms overlap, and people use them loosely. Here is how they usually differ:

Document	What it covers	When you use it
Outline	The plot, scene by scene or chapter by chapter	Before and during drafting, to know what happens next
Story bible	Facts about characters, places, timeline and style	Throughout writing and revision, to check consistency
Series bible	A story bible that spans several books, plus open threads and plans for future books	Across a whole series
Style sheet	Spelling, formatting and usage choices only	Editing and proofreading

Many writers keep the outline inside the bible as a separate section. That works well, as long as you can find things quickly.

When to start a story bible

The best time is before you start drafting, even if the first version is thin. A page of character names and a rough timeline is enough to begin.

If you've already written a draft, start the bible during revision. Read through the manuscript and log every fact as you go. It's slow, but it doubles as a continuity edit, and you'll catch errors in the process.

If you're midway through a series without one, build it from the published books before you write the next. Pay particular attention to character details and the timeline, since those cause the most reader complaints.

How to keep a story bible up to date

A few habits make the difference:

• Update at the end of each writing session. Spend five minutes logging anything new you invented: names, places, dates, physical details.
• Mark the source. Note the book and chapter where each fact first appears, such as "B1 ch. 7". When you need to check the exact wording, you know where to look.
• Separate canon from ideas. Keep a section for things you're considering but haven't put on the page. Only move them into the main bible once they appear in the text.
• Revise the bible when you revise the book. If you cut a scene, delete or flag the facts it introduced.
• Do a final pass before publication. Read the bible against the finished manuscript one last time, then lock that version as the canon for the published book.

Where to keep your story bible

Any tool works if you can search it and you'll actually use it. Common choices:

• A single word-processor document with headings for each section. Simple, searchable and easy to share.
• A spreadsheet for the timeline and character traits. Sorting by date or by character is useful for big casts.
• A folder of notes, one file per character or location, linked together. Good for large fantasy worlds.
• Index cards or a notebook for writers who think better on paper. Photograph the pages so you have a backup.

If you draft with AI help, the same idea applies. Inkora's AI novel writer starts by planning a book bible from your brief, with premise, characters, a style guide and a chapter-by-chapter outline, which you can edit before any chapters are written. It then writes each chapter with continuity notes, a locked narrator voice and a fact ledger so the book stays consistent with itself. That bible covers one book at a time. Inkora doesn't plan across a series, so for a multi-book series you'd keep your own series-level bible and feed the relevant details into each new book's brief. For more on how this kind of workflow fits together, see how to write a book with AI.

Common problems and fixes

The bible got too big to use. This often happens with fantasy worlds. Fix it by splitting reference material (history, lore) from working material (characters in the current book, active timeline). Keep the working section short enough to scan in a minute.

You stopped updating it halfway through the draft. Don't try to catch up from memory. Finish the draft, then do a dedicated read-through and log every fact. Treat it as part of your revision pass.

You found a contradiction in a published book. Decide which version is canon going forward and record it in the bible. If the error is significant and the book is self-published, you can correct the manuscript and upload a revised file through your store dashboard. Check each store's own process for updating a live book. Our guide on how to self-publish a book covers the basics of managing files across stores.

Two versions of the bible exist. Pick one file as the master, merge the other into it, and delete or archive the duplicate. Keep the master in one place with a backup.

You're spending more time on the bible than on the book. The bible serves the story, not the other way round. Record facts that appear on the page or that you'll definitely need. Skip lore nobody will read.

Collaborators keep contradicting it. Share a read-only copy with editors and narrators, and ask them to send queries rather than edit directly. You stay the single keeper of canon.

A story bible is a working tool. It records what's true in your fiction so you don't have to remember it. Start small, update it as you write, and it will save you from the errors readers are quickest to spot.
