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 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 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 keeping the story bible beside your manuscript.
