HORROR — Universe Craft Rules
Scope: HORROR universe stories only. Universal prose rules live in docs/CRAFT.md (Base layer) — clarity standard, scene architecture, sentence/voice rules all apply here unchanged. This file adds what GLMZ/SCRY/NONFICTION don't need: the specific discipline of sustained, unresolved dread — how to escalate wrongness without collapsing it into either a monster manual or a tidy answer.
0. What HORROR is
HORROR is Prose's contained-horror fiction universe. Unlike GLMZ (one continuous cyberpunk metropolis) and SCRY (one continuous fantasy world), HORROR is anthology-shaped: each book stands in its own real-world-adjacent setting, with no requirement of shared geography, timeline, or antagonist across books. What every HORROR book shares is not a world — it's a method: one clean transgression against a rule of reality, escalated through specific, technically credible detail, never fully explained.
The flagship exemplar is QRT — an amateur-radio operator being reconstructed, pattern by pattern, by something that was never listening to the signal at all.
1. Ambiguity Is Structural, Not Decorative
The antagonist force in a HORROR book is never given a taxonomy, an origin, a name, or a stated goal. The story may let the protagonist construct a hypothesis — even a rigorous, technically grounded one — but the narrative itself never confirms it. A hypothesis that turns out to be half-right (true enough to explain some events, wrong enough to leave the protagonist exposed when it fails) is more effective than either a fully-explained mechanism or a shrug.
Hard rule: if a beat's prose states the antagonist's nature as narrative fact rather than protagonist inference, that beat has failed HORROR's core discipline — flag and fix it, don't publish it. Confirmation is death for this universe the way an internal-understanding ending is death for GLMZ.
2. Escalation Through Small Wrongnesses
Before any overt reveal, the prose must accumulate specific, checkable wrongnesses — details a careful reader (and the protagonist) could verify and that are almost, but not quite, right. A detail that's completely alien reads as fantasy; a detail that's subtly wrong (a callsign correct except for one digit, a signal report the protagonist would give but didn't) is what makes it dread rather than spectacle. Escalation curve: verifiable-detail wrongness → pattern recognition → the protagonist's own controlled experiment → the experiment's result exceeding what the protagonist's hypothesis predicted.
3. The Observer-Effect Discipline
Locked mechanic available to any HORROR book that wants it (originated in QRT): an uncanny phenomenon that cannot occur while the protagonist is actively, attentively observing the exact channel they think is compromised. This isn't invoked as hard science — the protagonist may reach for the language of quantum observation because it's the framework their own technical literacy hands them — but the story never adjudicates whether that framework is literally true. Its narrative function is to manufacture false safety: the protagonist tests the wrong layer, confirms the phenomenon can be suppressed by watching there, and stakes their safety on a hypothesis that only holds for the channel they happened to test. The turn is discovering the leak was never in the observed channel at all.
4. Endings
HORROR does not default to GLMZ's avalanche-no-epilogue or SCRY's permanent-death convention. The default HORROR ending is the cold/ambiguous close: the immediate threat drops off-page, time passes without incident, and then one final concrete detail confirms the thing never stopped — it simply stopped needing the protagonist's participation. No epilogue processes the horror into meaning; the last image is procedural and understated, not operatic.
5. Technical Authenticity Is the Credibility Engine
Ambiguity only works if everything adjacent to it is exactly right. When a HORROR book is built around a specific subculture or technical practice (amateur radio, analog recording, a trade), get the jargon, procedure, and equipment correct to the letter — Q-codes, PTT discipline, key clicks, harmonic signatures, logbook conventions. A reader who knows the domain and catches a factual error stops trusting the ambiguity everywhere else in the book.
6. Violence and the Body
Where HORROR includes physical harm, docs/CRAFT.md's body-true standard applies unchanged —
physical consequence, not spectacle. HORROR's inflection is that dread from wrongness usually
carries more of the book's weight than dread from violence; a HORROR book is not obligated to
include on-page violence at all.
