# What Is a Story Bible, and Do You Need One?

May 13, 2026 [Craft](https://usegalley.com/blog/tag/craft)

![An open notebook of character and location notes beside a manuscript](https://usegalley.com/images/blog/what-is-a-story-bible.png) TL;DR A story bible is a living reference for your book's characters, places, timeline, and rules. For a standalone novel it's optional. For a series, or any book with a large cast, it's the thing that stops you from renaming a character in chapter 20 or breaking your own timeline. Keep it beside the manuscript, not in a separate app you'll forget to update.

Somewhere around chapter fifteen, most writers can’t remember whether they wrote
“grey” or “gray” eyes, or which year the war ended, or how old the sister is
supposed to be now. A [story bible](https://usegalley.com/glossary#story-bible) is the answer to all of that. It’s just a
living reference for the facts of your book, kept in one place so you stop
contradicting yourself.

## What goes in it

- **Characters** - names, ages, appearance, voice, relationships, who knows what

- **Places** - geography, layout, what’s where, travel times

- **Timeline** - when events happen, and in what order

- **Rules** - the logic of your world, the magic system, the procedure, whatever
your reader will hold you to

The rule of thumb: if a reader could catch you contradicting it, it belongs in
the bible.

## Standalone vs. series

For one self-contained novel, you might hold it all in your head, and
that’s fine. You need the bible the moment the book gets big: a large cast,
a complex timeline, or more than one book.

For a series it’s not optional. Book three has to agree with book one, and you
wrote book one two years ago. The bible is the only reason your readers, who
remember your world better than you do, won’t catch the seam.

## The continuity errors readers actually notice

They notice names, timelines, and physical details. An eye colour that changes.
A character who’s 34 in one chapter and 37 in another with no years passing. A
Tuesday that becomes a Thursday. None of these break the plot, but every one of
them quietly tells the reader you weren’t paying attention, and that’s a hard
thing to win back.

## Keep it next to the writing

The part that matters: a story bible only works if it’s current,
and a bible in a separate app is a bible you stop updating the second the writing
heats up. The friction of switching windows is enough to kill it.

That’s why [Galley’s story bible](https://usegalley.com/features/story-bible) lives right beside the
manuscript instead of in another tab. Type `@` to drop in a character or `#` for
a place, and the name
stays spelled the way you defined it. Because it’s a keystroke away, you
keep it up to date. More on that in
