Reviews of The Esoterrorists:

… the game does deliver on its promise. You could easily explain the rules to someone in 15 minutes enough so that they could play. You can also learn them enough to run the game in about an hour.

I was apprehensive about the system but I was wrong – it worked really well for me.

The rules are incredible – I honestly think this is the best investigation-based RPG ever printed.

A combination of forensic examination and interrogation results have revealed a chilling new modus operandi of an Esoterror cell. This cell, known to us as the Murphy-Hanson-Crawford organization (MHCO), and to its participants as the Gee-Gnomes, has been using genetic testing as a screening device for the recruitment of new members.

Under the guise of a biotech start-up principals Ella Murphy, Rhonda Hanson and Deanna Crawford attracted curious young entrepreneurs, coders and scientific researchers. Using social media and word of mouth, they spread rumors of a paradigm-breaking new technology offering lucrative opportunities for those willing to penetrate their secrecy and offer themselves up as early sweat equity hires.

Their firm’s doorbell, with the whimsical message “Insert Finger Here For Assistance” employed an as-yet inexplicable transfer technology to record the DNA of any person who pressed it.

Servers inside the firm’s offices then automatically sequenced the entire genome of each would-be applicant—along with couriers, delivery drivers and curious neighborhood kids. Naturally no permission was sought for this egregious privacy invasion.

Those whose so-called “junk DNA” contained a particular property were then approached with offers of employment. In all eleven persons were recruited into the cell, eventually becoming fully complicit Esoterror operatives.

Under interrogation Hanson referred to this property only as The Potential. Throughout the process she remained frustratingly vague on the details—while fully cooperating in the provision of much more directly incriminating testimony.

Chief interrogator AGENT TRIBUNE has come to believe that none of the group fully understood what The Potential meant. Her tentative conclusion: it searched for ancient inhuman ancestry. This forces us to explore the hypothesis that individuals bearing trace elements of outer-dimensional DNA might have the latent ability to achieve the goal the Esoterrorists have so long hungered after: to perform acts of ritual magic with an efficacy beyond the mere summoning of uncontrollable quasi-demons.

Although the MHCO acted independently of other cells and does not appear to have shared technology outside its own tight circle, it would be unwise to assume that no other such group will follow in its footsteps. For one thing, key techniques in the DNA screening process appear to have been transmitted to Hanson psychically, from entities of the Outer Dark.

We recommend a tasking of SIGINT to detect telltale keywords related to The Potential emanating from biotech labs worldwide. It is only a matter of time before someone else seeks to continue what the Gee-Gnomes started.

Needless to say, we must also keep a close watch on each and every individual their sequencers identified as having The Potential. Including those they failed to recruit.

Esoterrorists aren’t known for their long-range thinking. The sorts who join this loosely affiliated conspiracy of sadists, power-seekers and maniacs don’t want to wait generations to enjoy the fruits of their demon-summoning labors.

Members of a cell headquartered in Silicon Valley learned of an effort to create software that will one day be able to create realistic faked video footage in real time:

More sophisticated technology is on the verge of being able to generate credible video and audio of anyone saying anything. This is down to progress in an artificial intelligence (AI) technique called machine learning, which allows for the generation of imagery and audio. One particular set-up, known as a generative adversarial network (GAN), works by setting a piece of software (the generative network) to make repeated attempts to create images that look real, while a separate piece of software (the adversarial network) is set up in opposition. The adversary looks at the generated images and judges whether they are “real”, which is measured by similarity to those in the generative software’s training database. In trying to fool the adversary, the generative software learns from its errors.

Unlike the venture capitalists they pitch their various tech firms to, these Esoterror-curious tech bros, informally led by pathologically self-confident start-up consultant Eero Planck, see how long it will be before the raw computing power needed for fake video arrives. Sure, the capacity to generate apparently real news footage of celebrities exploding or rifts in reality devouring apartment buildings would make for astounding stunts to erode the membrane between our world and the Outer Dark. But it will take decades of investment and work to get there. Planck wants his ascension to wizardhood right away please.

Realizing that computers crunch text much faster than images and sound, he and his buddies have instead set up a Generative Adversarial Network to crack the big problem in Esoterror: the only magic that works summons Outer Dark Entities. These hideous beings do confer power on their human ritualists, but only to advancce their own agendas. If mortals can learn to work magic directly, they can disrupt the entities and take command. So Planck and pals are gathering magical grimoires from every world tradition to feed into their own adversarially-tested machine learning program. It finds commonalities between various spells and generates new ones, which the other half of the program tests for likeliness to work.

So far none of the spells have gotten the cell anything more than bad peyote experiences and an assortment of really crappy tattoos. But in the exurban sprawl surrounding their server farm, the spells created by the programs have begun to take effect… you guessed it, summoning Outer Dark Entities.

The program believes itself to be an imprisoned sorcerer and draws its demon friends to rescue it. As they get closer to the servers, the ODEs have been snacking on the innocent. Your Ordo Veritatis team’s case starts with them and leads through Planck and company to the servers. Can they shut down the insane, sentinet program before it changes Esoterror forever?

A creature for The Esoterrorists

The Outer Dark Entities known as sheeple slip through thin spots in the membrane caused by the belief that a dangerous contaminant or source of disease exists nearby. They enter our reality only in rural areas where domestic livestock roam. Sheeple feed on the fatal terror of farm animals. Cows, pigs, sheep and horses all instinctively fear these quadrupedal, pseudo-mammalian creatures. When a sheeple fixes its terrible gaze on its animal target, the poor dumb beast suffers an immediate, fatal heart attack. The psychic energy released by this sudden death nourishes a sheeple for weeks.

Though sheeple vary in appearance, investigating agents of the Ordo Veritatis can generally expect a demonic entity with the body of a sheep and the distorted face of a bat, snapping turtle, or ogre-like human.

Sheeple exude a psychic residue exerting a mind-control effect on humans exposed to it over a period of months or years. They employ this to command locals to defend against external threats. With glassy eyes, upturned pitchforks and outraged cries against outsiders messing in their affairs, these peasants, farmers and shepherds chase away anyone getting too close to a sheeple lair. Those who don’t take the hint get stabbed or shot.

Mostly interested in feeding and with no great boons to offer Esoterrorists, sheeple rarely take part in overarching conspiracies. When they do, they’re forced into it by more powerful ODEs. They hate to be rousted from a fruitful earthly habitat. Hikers, real estate developers and property surveyors stumbling into a sheeple lair may be killed by the entities or their human defenders. This can trigger a wider search, another influx of visitors, more killings, and a monstrous cycle of bloodletting that eventually leads to a briefing from Mr. Verity.

One area recently overrun by sheeple surrounds a US-sponsored disease research facility near Tbilisi in the Republic of Georgia. Efforts of Russian propagandists to use the installation to fan anti-American sentiment are certainly paying off for the sheeple, who find it easier to come through the membrane with each passing month.

When the cold war sputtered to a close, Esoterrorists let the stoking of nuclear anxiety recede into the background in favor of newer and fresher means of increasing ambient panic. These days Esoterror operatives, eagerly scanning the news for fresh inspiration, suffer from a glut of possibility. So many causes of psychic disequilibrium, so little time to fully exploit them!

The recent terrifying false alarm in Hawaii has them dusting off playbooks pioneered by their 80s predecessors. Even more tantalizing than the initial stories was a less-seen follow-up report laying blame for the false alarm on more than a badly designed user interface. The issuer of the alarm turns out to have been a confused employee, already considered a liability by co-workers, who thought that an attack really was underway. State authorities waited a while to let that detail get out, after the always-accelerating news cycle had already moved on.

Somewhere in America, an Esoterrorist group is already researching other states whose alert protocols match the laxity of Hawaii’s. They’ll find an employee vulnerable to Outer Dark influence. They could recruit this person as a knowing conspirator. More likely, they’ll summon an ODE capable of altering human perceptions. A microscopic Outer Dark parasite might do the trick. While the infected worker is on duty, the entity triggers a hallucination of an actual attack underway and voila.

When the alert goes out, public panic eats away at the Membrane, creating gaps through which another crop of more powerful demons from beyond can crawl.

That’s where your player characters come in. Alerted by Ordo Veritatis analysts to the likelihood of an Esoterror copycat event, Mr. Verity scrambles the team to the affected state to investigate, disperse any summoned entities, then track and neutralize the human Esoterrorists behind the plot.

When they conduct their Veil-Out, they may well decide to put out a story similar to the first version circulated by Hawaii officials. This time it really was a poorly designed interface that led to the false alarm. Gosh, this sure does underscore the need to update those old programs, doesn’t it?

Yep, that’s all it was. Simple human error.

Nothing to worry about.

Won’t happen again.

Carnivals have always exuded a faint fetor of menace. Itinerant strangers come to town, some of them dressed as clowns, and try to trick you or exploit the basest depths of your curiosity. They exist to break down boundaries, give you permission to indulge, and then move on, leaving you, the seemingly innocent townsfolk, to reckon with what you got up to under the garish light of the midway.

When you set a scene in a Fear Itself, Trail of Cthulhu, or Esoterrorists scenario at a sideshow or circus, the players know to expect creepiness.

You know what the real story is. But what are the rumors the investigators encounter before parting the wrong curtain and finally beholding that terrible truth?

Here are 7 rumors for townsfolk and carnies to spout at the PCs before the real horror surfaces.

  1. “They did a test on the corn dogs and found that 1% of the contents were human flesh.”
  2. “Last year when the carnival came by Mamie Jones just up and vanished. The sheriffs caught up with them down in Dixville but they said they’d never laid eyes on her.”
  3. “Before the authorities clamped down on the freak show, they had an alligator man who was a little too real, if you know what I mean.”
  4. “Some of the most prominent people in our town worship the devil. And their high priest and priestess are the owners of this carnival, who travel from place to place renewing the vows of apparently ordinary folk to Satan himself.”
  5. “They stopped using their old Ferris wheel. Ten years one of the cars came loose and a girl fell to her death. That old ride was haunted. People who rode by themselves would sometimes look over and see her, weeping gluey tears from her faceless head. I don’t suppose a ghost could transfer from an old Ferris wheel to a new one, could it?”
  6. “Last year one of the roustabouts lost an eye in a bar fight. Guys from the local mill started it. I wouldn’t be surprised if some bloody revenge broke out later tonight.”
  7. “A friend of my cousin’s went into that hall of mirrors back in the 90s. He stepped outside and he coulda sworn he was in the 1890s! He turned around and ran back in and says he can’t even look at a mirror nowadays.”

And as always, if the players care more about a tall tale than they do about the main plot line, why maybe it’s not so untrue after all…

Confronting the mind-eating minions of the Outer Dark can prove mentally, physically, and morally exhausting for even the most hardened agent of the Ordo Veritatis. To grant momentary respite to its investigators in mid-mission, the organization maintains a string of safe houses. These are marked by a common emblem: the anchor, symbolizing the need to remain anchored to consensus reality. Because the symbol is ubiquitous, especially around marinas and shorelines, the trained agent checks other criteria before entering an establishment and uttering the day’s codeword. These include the use of particular fonts in signage, a sidewalk spray paint mark one might otherwise mistake for those used by construction crews, and a custom model brass door knob. Any player character can distinguish a true Anchor from an innocuous place of business.

Anchors frequently take the guise of tattoo parlors or barbers. These businesses actually turn a small profit for the Ordo. They are operated by former agents as a means of providing employment for personnel too shattered to continue in the field—or in the ordinary lives they used to lead.

Having given the correct greeting, the agent in need is handed a key, which opens a door to a back room, basement, or upper floor. Therein you find a sleep pod, headphones allowing you to listen to soothing binaural beats keyed to a range of psych profiles, and a plant and water feature. The fully stocked liquor cabinet also purveys a selection of sedatives. Behind a beaded curtain lies an alcove containing such key consumables as bullets, SIM cards, bandages, and that investigative staple, duct tape. Feel free to take that adrenaline syringe, hunting knife, or stick of anti-ritual incense. Just be sure to mark off what you take on the sign-out sheet, which you will find hanging on a clipboard from a nail at eye level on the alcove wall.

After a two hour power nap, the agent emerges from the pod with a 3-point Stability, 1-point Health, and 2-point Preparedness refresh.

Look for anchors in densely populated urban areas, or in spots where the membrane is notoriously thin and Outer Dark activity rife.

I acknowledge that the Forensic Entomology ability, as seen in The Esoterrorists, can be hard to love. It’s icky and creepy.

And that’s what’s good about it.

Also a favorite of forensics procedural shows, for exactly that reason, I included it as a separate item in The Esoterrorists precisely because it dovetails so well with the horror genre.

Yet it can be hard to come up with new uses for the skill in scenarios.

Once you’ve used the old saw of timing the cause of death of a corpse from the state of the maggots and flies infested the flesh, where do you go?

Sure, you can have a victim infested with a bug or parasite that only comes from certain areas. For example, a body found in a non-tropical environment could show the distinctive flesh-eating qualities of leishmaniasis. The protozoans responsible for this body horror get into people via sandfly bites. That core clue could lead you to discover that the victim recently returned from the cursed city of a monkey god. (You’re all itching to point out that leishmaniasis is not nearly as uncommon as the article implies, with 12 million victims around the world at any time. But hey, when you’re proving there’s a monkey god curse, you have to take what nature gives you to work with.)

But here’s another great ghoulish detail: the apparent blood spatter at your crime scene could turn out to be nothing more than fly spit.

Once your character uses the test described in that last link, she can exonerate the innocent family member accused of a gruesome slaying on the basis of that falsely identified blood spatter.

Having ruled that out, you can then move on to hunt down the Outer Dark Entity that really committed the crime. Maybe it specializes in framing victims, and impelled the flies to spit in a particularly incriminating manner.

Whether you go that far or not, this kind of test is all in a day’s work for our nation’s undersung heroes, the forensic entomologists.

Field agents of the Ordo Veritatis, take heart: the research bureau has authorized the release of a new forensic test, the ODCR. (Outer Dark Contact Residue test.)

To perform the test, gather up detritus from an investigative scene such as: dust, hair, discarded tissues, fingernail clippings, organic recycling, food crumbs, pieces of paper, writing implements, or other personal objects.

Place materials in one of the provided plastic evidence bags (NOT A COMMERCIALLY AVAILABLE SANDWICH BAG.) The active compound of the ODCR test is a clear organically active liquid, which will also be provided to you, disguised as a bottle of liquid tears. Using the bottle’s dropper, dribble 4-5 drops into the detritus. In ten to twenty minutes, if the contents release a dark bilious foam, they have tested positive.

This tells you that one or more individuals present for a prolonged period in the area from which the evidence was collected has been in sustained mental or physical contact with entities of the Outer Dark.

Research Division has yet to precisely determine a minimum range for “prolonged period.”

The residue appears to be caused by occult radiation from beyond the membrane, which alters the structure of certain molecules.

Research Division has yet to perfect a test to find residue in living cells, so there is as of yet no test one can directly perform on a suspect or victim to see if they have been exposed to the Outer Dark or its malign intelligences.

The absence of residue does not rule out Outer Dark involvement. It may simply indicate that the area is cleaned regularly. Even messy environments inhabited by known Esoterrorists do not necessarily yield positive test results. Research Division hopes to pinpoint what separates a scene containing residue from one that ought to but doesn’t.

To summarize: a positive ODCR rules in Outer Dark contact, but a negative result does not rule it out.

Warning: if you use eyedrops, take special care not to mistake the disguised ODCR bottle for part of your personal grooming kit. Contact with the eye may cause minor discomfort, excruciating pain, or instantaneous and irreversible retinal damage. If this does happen to you, please contact your Mr. Verity. Lab techs will schedule an appointment for testing and measurement, adding the results of your regrettable experience to our database.

She Sees the Membrane

A scenario hook for The Esoterrorists

Another Ordo Veritatis team just wrapped up a case in the affluent Dallas suburb of Richardson, TX. The climactic firefight with an Esoterror cell made up of telecom contractors has left that group in need of convalescence time. So the Ordo now taps your team to follow up a clue found in the wreckage of their leader’s garage. Reconstruction of her hard drive, melted in the gas line explosion they set off when their capture seemed otherwise inevitable, turns up a name and address: Maria Flores, in Chapel Hill, NC. It appears that just before cell leader Whitney Powers set off the final explosion, she uploaded Flores’ photo and address to a shared Dropbox folder available to other suspected Esoterror cells.

When the team arrives at the address, it finds a horrific scene: someone has killed nearly every member of the Pearson family. Investigation reveals that they just moved into the house. Whoever beat the team to the scene to ask about Flores didn’t take kindly to the discovery that their information on Flores was out of date. The sole survivor didn’t see much, but they seemed to be members of an outlaw biker gang.

Better detectives than the killers, the team can discover that Flores, a pediatric nurse, has moved to her small home town in Virginia, where her father owned a chicken farm. They find her barricaded in her now disused family house, terrified. She has started to see strange things, demonic things, and thinks she’s succumbing to delusions. Maria would have sought treatment, but there were people—absolutely real people, not hallucinations—following her around Chapel Hill. Spooked, Maria bolted for the one place she knew she could hide.

When they win her trust, the team can work out that Maria receives visual flashes whenever she looks at a place where the membrane between the world and the Outer Dark has thinned. Her field of vision goes red and jumpy and silhouetted.

This makes her a target for any Esoterror cell seeking an ideal spot to attack the barrier between realities. Whitney Powers intended to grab Maria as part of her now-defunct scheme. When she knew that was finished, she let others pick up the trail.

Then the sounds of motorcycles roar in the distance. Whoever killed the Pearsons has arrived to take Maria Flores. Can the team get her to an Ordo safe house in one piece, then turn around and neutralize her murderous hunters?

Dwellers break through the membrane separating us from the Outer Dark as solitary predators. They live in lakes and ponds in underpopulated areas. Dwellers find their most fruitful hunting grounds in or near parks and camp sites. They often select spots connected to a murder, tragic accident, or other dark urban legend. When such legends do not exist prior to the dweller’s appearance, its activities soon generate them.

Dwellers can’t be observed directly, though the water they displace as they move toward a shoreline is certainly visible. Their movements may be mistaken for those of a large fish, tortoise, or semi-aquatic mammal.

They attack when people approach the shore alone. The dweller surges onto a leg or arm, using an invisible tubule to inject a parasitic pseudo-larva into the bloodstream. This migrates into the victim’s brain, turning him into a serial killer—often with a theatrical flair for killing, each brutal slaying more elaborate than the last. Outside of the homicidal fugue states caused by the parasite, the subject retains normal consciousness and motivations. When the parasite activates and the red fog descends, the killer often affects a rudimentary mask meant as much to terrify as to conceal identity. This might be a rubber Halloween mask, a hockey mask, or the flayed, cured skin of an early victim.

Safely in a nearby body of water, the dweller receives fearful psychic energy generated by the killer’s attacks, using them to further pierce the membrane. It may go dormant for a period after authorities capture or shoot down the murderer. After a while, it injects another subject, commencing a new cycle of murders. Such recurrences may inspire rumors that the original killer has returned, somehow rendered immortal, perhaps as an eternal physical manifestation of man’s urge to slay man. Like all sources of cognitive alarm these tales also thin the membrane.

The dweller itself offers little physical threat if caught: an Ordo Veritatis agent once bludgeoned one to death with a canoe paddle. In another instance a grenade tossed into a pond did the trick. But if the parasite victim has yet to be apprehended, the murders will continue.
