Build the dread.Keep every rule it breaks.

Dread is a structure, not a mood

The best horror novels feel inevitable when you reread them. The scratch at the window in chapter one, the grandmother who wouldn’t talk about the lake, the dog that wouldn’t go upstairs: each was a setup, placed on purpose and paid off later. Dread is the reader sensing that pattern before they can name it.

That only works if you remember every plant. Across a long draft, it is easy to forget a hint, pay off one you never planted, or leave the best setup hanging because you rewrote the chapter it came from. Authrot tracks setups from the text itself, so you can see which wrong notes are still waiting for their echo.

Horror also has to escalate. The first wrongness is small and deniable, the second is harder to explain away, and by the midpoint the characters can no longer pretend. If two chapters in a row deliver the same level of fear, the tension leaks out. Keeping a clear view of what each chapter adds to the dread is how you protect that climb.

Pacing the fear across the book

The horror starter suggests the seven-point structure, which suits the genre well: a hook, a first plot turn into the strange, a pinch where the threat shows its teeth, a midpoint where the characters stop running, a second pinch, a second turn and the resolution. Arcs hold goals, opposition, stakes and turning points, and chapters sit under the arcs they serve, so you can see where each scare falls in the shape of the whole.

Chapter plans carry the moments a chapter must land as a checklist, ticked when the chapter is read, so “the photograph has one more person in it” doesn’t get lost in the drafting. Prose stats show sentence length per chapter, a simple way to check that your attack scene really does speed up, and you hear when a chapter drifts from the arc it was meant to serve.

Plant it, track it, pay it off

When a chapter is read, the setups it plants are recorded with the line that made each one. The story map’s promises view sorts them by when they pay off: due now, left hanging, or the long game. Ask whether one has paid off and you get where, or hear that it is still being carried, or that it was dropped.

If you want a dropped setup back, put a reminder on an arc to bring it back there. Threads show every plot line down the chapters with the quiet ones flagged, which is how a subplot about the missing hiker stays alive through the middle of the book instead of quietly dying in a revision.

• Setups recorded with the words that planted them
• Grouped by when they pay off: due now, left hanging, the long game
• A check on any one: paid off where, still carried, or dropped
• Reminders on an arc to bring something back

A monster with rules

The horror starter in Foundations opens a lore entry called the threat: what it is, or what the characters think it is, what it wants, and its rules. The starter’s note is a good one to keep: the threat has rules, even when the characters never learn them all. Readers forgive mystery. They don’t forgive a ghost that ignores salt in one scene and is stopped by it in the next.

Anchor the rules you mean to keep, and chapter readings flag a contradiction against the fact it breaks. Events are kept in order too, so if you wonder whether the sceptic has been told about the cellar yet, the chapter where she was is on the record to check. When a rule is meant to break, the break is yours to write, on purpose.

Who survives, and who’s left

Horror thins its cast. Screen time shows presence, point of view and exits for every character in every chapter, so you can see the rhythm of your losses at a glance and check that nobody who died in chapter twelve walks into chapter fifteen. Facts that change over time, like a wound or a lost key, sit on each entry.

Connections draw the ties between the survivors from what the chapters say: family, lovers, rivals, the outsider. Slide back to any chapter to see only the ties that hold by then, which helps when the twist is that two of them were never what they seemed.

The haunted house is a character too. Give it a place entry with its rooms and history as traits and facts, and every chapter that relies on the locked attic or the flooded cellar is linked back to it, even where a scene is shaped by the place without naming it.

Folk, cosmic, haunted or psychological

The horror starter offers supernatural, haunted house, folk, cosmic and psychological horror, with a single viewpoint, an uneasy tone and a field for content boundaries: decide how much violence and gore is on the page. The voice templates include a slow-dread voice, so you can hear the same scene told twelve ways and pick yours by ear.

When you publish, a story answers its content warnings before it goes public, and readers can filter by them. Serial horror suits a schedule: bank chapters, give each a release date and time, and readers can follow each story’s feed for the next instalment.

Horror is also a genre people love to hear read aloud. Narration gives each character a voice of their own, with direction for how strongly it is acted and where it pauses, and readers can listen on the chapter page with the paragraph being read followed as it goes. Edit two paragraphs later and only those two are narrated again.
