The Bells of Harrow Keep Writing · Chapter 4 3 continuity errors caught and fixed
Architect Writer Logic editor Editor

    The writing room, in miniature. Watch the logic editor catch a timeline slip and send it back.

    Logic review

    It catches its own mistakes before you read them.

    Long AI drafts fall apart on details: a dead man speaks, a week becomes two days, a secret is known by someone who was never in the room. Here, a separate editor reads every chapter against the story so far and runs seven checks. Anything that fails goes back to the writer, and you see the whole exchange.

    • Timeline

      Days, seasons and ages add up from chapter to chapter.

    • Numbers

      Nine riders stay nine riders. Distances, debts and head counts hold.

    • Causality

      Nothing happens because of something that has not happened yet.

    • Who knows what

      No character acts on a secret they were never told.

    • Evidence and objects

      The letter that burned in chapter 5 is not read aloud in chapter 9.

    • Continuity

      Wounds, promises, locations and names carry forward.

    • Voice and audience

      The prose stays in the register your readers expect.

    Characters

    A cast that keeps itself current.

    Characters are created for you when the book is planned, then updated after every chapter: what they know, where they stand with each other, what changed and why. Chapter 30 remembers chapter 3, and you can read the whole record at any point.
