Continuity

Continuity is the consistency of everything factual in your story across its whole length. If chapter 2 says the cabin burned down, chapter 20 cannot have a character walk into it. If your protagonist learns the traitor's name on page 200, she cannot hint at it on page 90. Continuity is the quiet structure that makes a reader trust the world.

A continuity error is any break in that consistency. They cluster into a few types:

• Timeline. Events out of order, ages that do not add up, a Tuesday that becomes a Thursday.
• Knowledge. A character acting on information they have not learned yet, or forgetting something they clearly know.
• Object and location. A gun left in the drawer that appears in a coat pocket, a character in two places at once.
• World rules. Magic or technology that works one way early and another way later, with no reason given.

Why continuity is hard in a long book

The problem is scale. A novel holds thousands of small facts, and you cannot keep all of them in working memory while you draft. Errors creep in not because the writer is careless but because no human tracks 80,000 words of detail perfectly. This is exactly where AI tools tend to fail worst, because they generate fluent prose with no memory of what they wrote ten chapters ago.

How a continuity editor helps

A continuity editor checks new prose against the story bible and the character knowledge state, then flags contradictions for you to resolve. It does not rewrite your work. It points and lets you decide, because sometimes a "contradiction" is a deliberate lie a character tells, and only you know that. FireQuill runs these checks as you write so problems surface while they are cheap to fix, not in a final read-through.
