or, When Your Car Battery Goes Dead Outside the Jorgamundr’s Lair, It Ain’t No Coincidence

A Column on Roleplaying

by Robin D. Laws

Your assignments for the Ordo Verititas take you into zones where the membrane between our reality and the terrifying realm of the Outer Dark nears the breaking point. In such places you may encounter signs and symptoms of this damage bearing only an acausal relationship to the conspiracies and entities you hunt. The Esoterrorists, and the monsters they foolishly truck with, don’t directly cause these phenomena. Nonetheless, by rolling up the target terror cell, and, more importantly, conducting a veil-out to disguise its true nature from an unsuspecting populace, you can restore the membrane. This brings about a rapid drop-off in TMP (Thin Membrane Phenomena) in the afflicted area.

Though unrelated to your primary mission, these low-level manifestations can nonetheless exact a toll on the psyche. Repeated exposure can in extreme cases compromise agent mental condition, and with it successful mission execution. On the up side, they can help you narrow your quest when more concrete leads grow scarce. The closer you come to people, places and things related to the Outer Dark, the more of these manifestations you will encounter. When their frequency increases, you know you’re on the right track.

Common manifestations include:

  1. Enhanced pareidolia. The pattern-seeking of the human perceptual array encourages us to see familiar shapes, most notably faces, in random visual assemblages. In CMZs (Compromised Membrane Zones), this effect increases, independent of the viewer. Ordinary random patterns take on the terrifying faces of the entities you are chasing, or of innocent people murdered during the current case. Agents report seeing enhanced pareidolia effects in clouds, ice crystals on windows, knots of wood, peeling house paint, stains from water or other liquids, or even, as in the accompanying photo, in the cooking froth from starchy vegetables.
  2. Sudden animal death. Maddened wild creatures may burst from the wilderness to drop dead at your feet—after briefly menacing you of course. Likewise with household pets.
  3. Where the animal does not inexplicably die before your eyes, partial remains might later be discovered, as if from inexplicable predation. In one case, all of an informant’s aquarium fish were found by agents to have been skeletonized. The manifestation affected multiple tanks, and occurred in the room of the witness’ home where an interview was taking place. It occurred in an instant, when neither agents nor the informant were looking directly at the tanks. In more typical instances the head of the animal is found, but nothing else. Cattle mutilation (less commonly reported to also target horses and large working dogs) might be regarded as a subset of this phenomenon, or a separate one. Agents are cautioned to distinguish between this complex of CMZ collateral symptoms and direct predation by Outer Dark Entities, many of which require considerable quantities of protein to remain in this dimension for prolonged periods.
  4. Extreme vermin infestation. Pest animals suddenly infest an area that should not be vulnerable to them. They do so either in unlikely numbers or out of season for their vermin type. Reported cases from our incident reports include rats, bats, cockroaches, ants, and worms.
  5. Carcass materialization. A dead animal spontaneously appears somewhere it should not. For example you find a rat or writhing maggot mass in your milk carton.
  6. Localized weather. CMZs often suffer markedly worse climatic conditions than the immediate area. You may also encounter supernaturally brief flashes of inclement weather. Ordo Veritatis case files record sudden and meteorologically inexplicable bursts of hail, lightning, freezing rain, fog, tornadoes, and typhoons. Overcast skies cover Compromised Membrane Zones so inevitably that their presence becomes unremarkable.
  7. Fortean precipitation. This phenomenon was discovered by documenter of the unknown, and eventual Ordo Veritatis asset, Charles Fort (1874-1932.) An unlikely substance, object or animal falls from the skies, without apparent source. Examples drawn from case files include beans, roof tiles, mud, oil, excrement, shrapnel, shredded morgue documents, debris from long-vanished airplanes, and the proverbial frogs. When blood precipitates during an investigation, protocol requires you to test its origin. It may be that of an animal, human, or Outer Dark Entity. Some apparent blood falls turn out to be other substances entirely, from liquefied autumn leaves to stage blood.
  8. Electronic equipment anomalies. Clocks gain or lose time. Harsh whispers in Sumerian or Proto-Indo-European emanate from cell phones. Phantom fingers type threats or indecipherable messages on laptop keyboards. Televisions and personal stereos pop suddenly on, their content either directly disturbing or ironically innocuous. The tendency of batteries, particularly of cars, flashlights, and mobile communications devices, to go suddenly dead becomes so commonplace in a CMZ that you should plan for none of these to work when you need them most. Beware also the effect that may cause the vehicle you drove to your final confrontation to move or vanish.
  9. Materials degradation. Ambient Outer Dark energy degrades molecular bonds, rapidly aging commonly used construction materials. ODE manifestations are drawn to older, already decaying structures as it is. However even newly built homes, offices and installations can fall prey to this effect. Wallpaper glue weeps and melts. Stairs crumble, as if riddled by wood rot. Locks wear out or seize up. Screws and nails work themselves loose from surrounding wood or drywall.
  10. Psychic imprinting. Locations absorb extreme negative emotions, which can be released when ambient Outer Dark energy levels increase. You may witness ghostly replays of an area’s noted past murders and violent accidents. Some agents report complex interactions with events, as if drawn back in time to take part in them. Curiously, evidence of their actions in the past may later surface. Through this means an agent active in the late 1990s found herself in the background of the Zapruder footage of the John F. Kennedy assassination—an anomaly whose veil-out cost the organization significant effort and financial resources.

GMs, when you need a random creepy thing to reintroduce a mood of horror simply generate a random number and pick a creepy omen from this list. Or choose a manifestation thematically related to the current case. Give this column to your players in advance, or let them clearly deduce when an effect is key to the case, and when it is a collateral one like those covered here.

    “We’ve identified the blood that rained on you.”
    “Great. Whose was it?”
    “Yours.”
