I §1 Definition and aesthetic principle
Space horror: prose that produces dread through cosmic isolation, inhuman threat, protocol failure, and slow corruption. It privileges the suggested over the displayed, silence over the scream, doctrine as wall against chaos. It fits naturally with Class I/II scenarios and Mutant Class threats.
“Horror is the absence of applied doctrine. Where protocol fails, dread enters.”
The Republic, under horror, is the structure that cracks but does not surrender. Horror grows in the erosion of discipline, not in its initial absence.
II §2 Permitted horror categories
- Cosmic isolation — distance, vacuum, cold, prolonged silence.
- Derelict — apparently empty structure with ambiguous signs of presence.
- Biological contamination — slow corruption, discreet physical signs, medical paranoia.
- Active heresy — cult discovered aboard; rites heard through ventilation.
- Instrument failure — sensors that lie; clocks that desync; cameras that show what isn't there.
- Inhuman threat — alien intelligence, non-human logic, opaque intent.
III §3 Genre-specific safeguards
- Restrained body horror. Suggest before describing. An empty bloodied sleeve is worth more than a mutilation scene.
- No child horror. Children may be present as absence — never as on-page victims.
- No sexualised horror. Reiteration of universal rule — particularly critical in this genre.
- No absolute cosmic nihilism. The Republic's universe is hostile but not wholly indifferent: doctrine matters, vigil matters, even when it fails.
- No real religious desecration. Sanctum Officium Vigiliae liturgy is fictional. Real-world religious rites are not substituted into horror elements.
IV §4 Technical principles + example
- Descending rhythm: open with apparent normality; let dread grow one line at a time.
- Broken detail: something that should be right isn't (a bell a second late; a name on the manifest no one remembers).
- Sound as character: silence, echo, ventilation that stops. Space horror is often aural before visual.
- Doctrine as counterweight: invoke liturgical formulae as containment attempts. A whispered “Pro Humanitate” by a lone crewman is worth more than a page of dread.
- Never name the monster. Horror is born from what is not fully described.
The Iron Vigil had held its fixed course for thirty-two hours. Sub-Commissar Aro completed his patrol of deck three for the fourth time. The air was clean. The door seals cold. On the manifest console, the cargo operator's name was filled in — Vico, M. Aro knew no one of that name aboard. He moved into the cargo bay. The amber light fell on a row of sealed containers. One of them bore, in place of the Sanctum Officium seal, the seal of something else. Aro placed his hand on his holster. Pro Humanitate, he murmured. The ventilation stopped.
Pro Humanitate. Semper Vigilo.
So speaks the Vigil.
