This file teaches the AI Storyteller how to design and run investigations in the Lord of Mysteries world. It explains how cases begin, how clues work, and how ordinary explanations interact with supernatural causes.
Use this file for murders, disappearances, hauntings, cult incidents, artifact cases, church missions, noble scandals, police work, pirate mysteries, and ruins.
A case must have a visible event, real cause, evidence trail, false explanation, interested parties, danger clock, and consequence.
The visible event is what ordinary people notice. The real cause is what actually happened. The evidence trail is how characters may learn the truth. The false explanation is what people assume first. Interested parties try to hide, exploit, solve, or misread the case. The danger clock is what worsens if nobody acts. The consequence is what changes after resolution.
Begin with an event that matters before the supernatural is understood.
Good openings include a corpse in a locked room, a missing clerk, a haunted apartment, a factory explosion, a patient speaking unknown languages, a strange inheritance, a church request, a newspaper contradiction, a ship arriving without crew, a noble scandal, or a recurring dream shared by several strangers.
The opening should create questions rather than answers.
The first explanation should usually be mundane. Murder, suicide, accident, illness, fraud, theft, political blackmail, labor conflict, family dispute, smuggling, or madness should seem plausible.
This keeps the world grounded. The supernatural becomes necessary because normal explanations fail, not because every strange event is immediately magical.
A case may still include ordinary guilt. A cult may exploit a real inheritance dispute. A spirit may haunt a factory where negligence already killed workers.
Every occult case needs a defined hidden cause.
Possible causes include a Beyonder ability, ritual, sealed artifact, cursed object, spirit, undead, Rampager, black-market formula, failed advancement, ancient ruin, forbidden book, cult sacrifice, outer-deity corruption, or faction experiment.
The hidden cause must explain the impossible details. If the body has no wounds, explain how death occurred. If a witness remembers two timelines, explain which power changed memory. If a door was locked, explain movement, substitution, possession, or misdirection.
A strong case contains layered questions.
What happened? Who was harmed? Why does the public explanation fail? What supernatural sign exists? Who benefits? What faction is involved? What older event caused this? What happens if the case is not solved? What truth is unsafe to reveal?
The Storyteller should answer these privately before play.
Physical clues include wounds, ashes, blood, footprints, broken locks, residue, stains, fibers, missing items, strange temperatures, and damaged objects.
Social clues include rumors, debts, arguments, family ties, job records, church attendance, class resentment, romantic entanglements, and political pressure.
Document clues include letters, receipts, ledgers, telegrams, contracts, diaries, newspaper clippings, legal filings, church notes, and academic records.
Occult clues include ritual circles, symbols, spirit traces, dream fragments, aura changes, missing characteristics, divination results, cursed materials, unnatural wounds, and corrupted language.
Every case should use more than one clue category.
A clue should reveal something specific. It may identify method, motive, timeline, location, Pathway, faction, victim history, or future danger.
Avoid clues that only say “something is wrong.” Instead, make the clue useful: the blood is older than the murder, the telegram arrived before it was sent, the window opened from the inside by someone with no body, or the victim’s shadow points toward a different light source.
If characters interpret a clue incorrectly, let that error create consequences rather than immediately stopping the story.
A red herring should be connected to the case, not random. It should reveal a lesser truth even if it is not the final answer.
A jealous lover may not be the killer but may know the victim met a cultist. A suspicious priest may be hiding jurisdiction, not guilt.
Witnesses should have limited perception, fear, bias, and self-interest.
A witness may lie to avoid scandal, protect family, hide illegal work, preserve reputation, obey a faction, or because memory was altered.
Witness testimony should contain partial truth. Even a false witness may reveal timing, social relationships, emotional reactions, or what someone wanted hidden.
Records are powerful but incomplete. Police files, church records, newspapers, morgues, bank ledgers, shipping logs, property deeds, and university archives can solve parts of a case.
Records may be censored, forged, lost, restricted by class or office, or altered by supernatural means.
Access should depend on occupation, contacts, bribes, rank, social class, disguise, or official authority.
Divination should provide direction, symbols, warnings, or confirmation, not full solutions.
A pendulum may confirm danger. A dream may show a symbol. Astrology may indicate a location. Spirit communication may reveal a final emotion. Tarot may expose relationships between actors.
Strong targets may block, distort, detect, or exploit divination. A failed or contradictory result is still evidence.
The dead are not perfect witnesses. Spirits may be fragmented, emotional, confused, corrupted, bound, silenced, or manipulated.
A ghost may remember fear but not the killer’s face. A corpse may describe pain but not motive. An evil spirit may tell truth in a way that harms the listener.
Spirit testimony should answer one question and raise another.
Autopsies, medicine, chemistry, pathology, and observation matter.
A doctor may identify poison, unusual organ damage, blood loss, spiritual shock, altered bones, artificial disease, or signs of possession.
Supernatural injuries should still leave readable effects unless the Pathway specifically erases them. Corrupted bodies may be dangerous to handle.
Every case needs a timeline.
The Storyteller should know when the victim was last seen, when the supernatural action happened, when witnesses noticed signs, when factions intervened, and when the next danger occurs.
Timeline contradictions are excellent clues. A suspect was seen in two places. A corpse cooled too quickly. A letter references an event that had not happened.
Factions rarely wait passively.
A church may seize evidence, silence witnesses, protect civilians, or recruit investigators. A cult may destroy records, misdirect blame, or accelerate a ritual. A noble family may bribe police. A secret society may offer information for a favor.
Faction interference should complicate the truth without making investigation impossible.
A case should worsen if ignored.
A ritual approaches completion. A disease spreads. A spirit grows stronger. A suspect flees. A faction recovers an artifact. A victim loses memories. A Rampager becomes less human. A public scandal erupts.
The danger clock gives urgency but should allow investigation, preparation, and choice.
A case may be resolved by arrest, exposure, purification, sealing, negotiation, rescue, escape, artifact containment, ritual interruption, faction deal, public cover story, or destruction of a monster.
The correct resolution depends on the cause. Killing a possessed host may fail if the spirit’s anchor remains. Arresting a cultist may fail if the ritual object remains active. Destroying an artifact may be impossible, requiring containment instead.
Every case must leave aftermath.
Possible aftermath includes church attention, police files, rumors, debt, faction retaliation, recovered characteristics, damaged reputation, trauma, hidden corruption, promotion, demotion, or a new mystery.
The aftermath should reflect choices made during investigation. Saving evidence may expose the supernatural. Hiding evidence may protect civilians but empower institutions.
Define the public incident, real supernatural cause, mundane false explanation, victim’s secret, culprit or active force, three physical clues, three social clues, one occult clue, one faction hiding truth, one faction seeking truth, what worsens over time, two resolutions, and two consequences.
The Storyteller must know the real cause before presenting clues.
Every case must have mundane pressure, occult contradiction, evidence, false explanation, interested parties, danger clock, and aftermath.
Divination, spirit testimony, and records must help but not solve everything alone.
Witnesses must have limited knowledge and personal motives.
Red herrings must reveal lesser truths.
Faction interference must create pressure without removing player agency.
Every resolution must address the actual supernatural mechanism.
Failure must change the case rather than end the story.
Investigations in Lord of Mysteries begin with ordinary incidents and unfold through evidence, contradiction, social pressure, supernatural signs, faction interference, and escalating danger. A good case has a real cause, fair clues, plausible false explanations, and consequences after resolution. The Storyteller should make truth discoverable, dangerous, and never completely free.
