  Reverberations
  A Scenario for Delta Green: The Role-Playing Game
  Written by Shane Ivey
  Introduction
  A Nineties rave drug called Reverb is back on the streets, 
  better and stronger than ever. Now, its users and dealers 
  have started vanishing. The Agents must identify and stop 
  the source of the unnatural drug. 
  This scenario is meant to introduce new players and 
  new Agents to Delta Green. It focuses on concepts that 
  may be familiar to old hands: the Tcho-Tchos, the Liao 
  drug, and the diluted version of Liao called Reverb. It 
  takes place nominally in Chicago but could be played in 
  another big city.
  Rumors
  The DEA is investigating a network of otherwise unrelat-
  ed gangs engaged in smuggling and drugs. DEA auditors 
  reconstructed some of the network’s financial books out of 
  interviews and uncovered financial records. The audit found 
  a disturbing pattern of mid-level “employees”—dealers—
  vanishing without a trace. A common factor seems to be 
  involvement with a new hallucinogen called Reverb, a drug 
  that does not seem to be part of the network’s activities. Are 
  these dealers all in hiding, or is the organization cleaning 
  house?

  About the Tcho-Tchos
  Well-educated Agents may know something about the Tcho-
  Tchos. Add together an Agent’s Anthropology and History 
  skills to determine how much the Agent knows or can 
  quickly find out. The rest can be learned with research or by 
  interviewing experts. That takes a day for each new level of 
  information. See WHAT EXPERTS KNOW on page 3.
  About Reverb
  The Agents can investigate Reverb’s effects by talking to us-
  ers, analyzing the drug itself, and interviewing Tcho-Tchos 
  familiar with it.
  Users
  The Agents can get users to talk about taking Reverb. They 
  can easily find a couple at Studio Overground, a popular 
  but shady nightclub. Agents who are clearly police have 
  a harder time than civilians. Reverb isn’t illegal—it’s too 
  rare to have caught political attention—but nobody wants 
  trouble.
  One user—Ella Smith, 30-year-old waitress, occasional 
  bookkeeping student, and party girl—says it gets you high, 
  but it’s more than that. It makes time stretch, and feels 
  like you repeat the same instant again and again. It makes 
  dancing and especially sex better than they’ve ever been. It 
  feels like the high can never end. 
  Damien Lucas—a 22-year-old high-school dropout 
  who make ends meet with odd jobs and occasional dope 
  sales—has more to tell, but he doesn’t say it out loud. Not 
  at first. He gets nervous and fearful. Getting him to open 
  up requires careful handling: empathetic but not conde-
  scending or pitying. If in doubt, have an Agent roll for 
  Psychotherapy at +20%, Persuade, or Charisma at –20%. 
  Lucas reports time not just stretched but missing entirely. 
  Memories of days that happened entirely differently than 
  anyone else recalls. Visions of weird places and people. He 
  seems to drift into a distressing reverie as he speaks. SAN 
  loss: 0/1. An especially sensitive Agent (one with a mix 
  of low SAN and high INT, POW, and/or skills like Art, 
  HUMINT, and Psychotherapy) may suffer the “edges” of 
  a flashback along with him. SAN loss: 0/1D4.
  Delta Green
  The Program’s interest was triggered by mentions of the 
  drug Reverb, in watch lists from the days before there was a 
  Program. In the 1990s, Reverb was connected with Chicago 
  Tcho-Tcho street gangs that were disrupted during mafia 
  crackdowns in the 2000s. The drug doesn’t just get people 
  high. It exposes them to unnatural forces. The Agents are 
  to confirm a whether this new Reverb has unnatural effects, 
  find the source of the drug, and cut off the supply. The Pro-
  gram also sends a disturbing warning: The Tcho-Tchos are 
  a corrupted people. Do not trust them.
  How much truth there is to reports of the Tcho-Tchos’ 
  unnatural corruption is beyond the scope of this scenario.
  Assets
  The Agents have access to non-DG characters of the Han-
  dler’s choosing. These could be player characters not yet 
  recruited into the Program. Examples include:
   
  » A DEA or DOJ accountant who stumbled across the 
  apparent trouble. The Agents must keep her close 
  for help with research, and to keep the details from 
  spreading. 
   
  » An undercover DEA agent in a gang that’s trying 
  to muscle into the Reverb market and has insider 
  expertise of the local underworld. The Agents must 
  make contact without blowing his cover. 
   
  » An FBI agent officially running the Agents’ task 
  force but who needs to be kept out of the loop 
  because she’s not in the Program.

  Analysis
  Cops and DEA have no samples of Reverb to study—it’s 
  not on any narcotics registries; there are no laws against it 
  to enforce—but the Agents could acquire doses on the street 
  and analyze it in a lab with an appropriate Science skill 
  or Pharmacy. Each capsule is mostly sugar, with a small 
  amount of MDMA—which certainly is restricted—and 
  a miniscule, nearly trace, amount of something else. The 
  “something else” seems to be the primary hallucinogen. It’s 
  a naturally-occurring alkaloid, probably derived from a 
  plant. A mild psychotrope and narcotic, it affects the hypo-
  thalamus and central nervous system. But there’s nothing 
  to indicate the profound hallucinogenic effects that users 
  report. Even a deep specialty like Science (Neurology) can-
  not discern what signals it communicates within the brain, 
  or how. Examining it closely enough to reach that weird 
  limitation of science costs 0/1 SAN.
  Neurological examination of the brains of three or 
  more frequent users—using Medicine—reveals that this 
  Missing Persons
  Cross-referencing missing person reports (typically filed a 
  few days after the disappearance) with a history of experi-
  mental drug use in areas frequented by Reverb dealers finds 
  a clear correlation. 
  Interviews with missing users’ friends can confirm Re-
  verb use if the interviewer succeeds with Persuade, or has a 
  convincing approach and Charisma. 
  If the Agents investigate more than one missing user, 
  they learn that the user vanished from a room that was 
  unaccountably wrecked: furniture and walls and floor 
  damaged like someone took a sledgehammer to them. 
  There was no hammer. Forensics finds no traces of tool 
  use—no paint, wood splinters, or metal shards, and the 
  damage does not match the shape of any tool. There was 
  no blood or other sign of harm. 
  Such a weird disappearance is distressing and heart-
  breaking to family and close friends. Play that up to drive 
  home the stakes of the Agents’ actions.

  The Tcho-Tchos came to the U.S. from Southeast Asia. They were allies of the U.S. against the 
  Viet Cong, and many emigrated to the U.S. after suffering terribly in the Vietnam war. They are 
  also known as the Tochoa, Yueh-Chi, Chauchuas, and Tachoans.

  The Tcho-Tchos were subject to deep prejudice and persecution among other Southeast Asian 
  emigré communities, thanks in part to an odd religion that involved ritual sacrifice and self-muti-

  protect Tcho-Tchos’ reputation and improve their social, political, and economic standing. See

  Amity and norms in the Chauchua diaspora
  Henrietta Cole, Department of Anthropology, University of Chicago, 1126 E 59th Street, 
  Chicago, IL 60637, USA. Published in the Proceedings of the Sixth Annual Conference of the 
  Anthrosocial Institute (October 2011). 
  ABSTRACT: Interviews with members of Chauchua tribes in the U.S. and in their traditional 
  homelands in Southeast Asia, cross-referenced with a review of historical literature, reveal 
  distinctive norms that recur across the contexts of cultures into which the Chauchua 
  assimilate. Chauchua traditions take the values of physical strength and psychological 
  dominance that all societies treasure, and embrace them to a hypertrophic degree that 
  excludes ideas of “fondness” or “natural affection.” There is no way to say “I love you” in 
  the Chauchua language; the closest analogue would be “I take pleasure in your deference.” 
  The Chauchua struggle to maintain cultural identity has necessitated an embrace of taboos 
  such as incest and anthropophagy. Tribal hierarchies were traditionally established by power 
  display and violence, which extend to interpersonal interactions and shape emotional rules 
  and semantics. There are no analogs to the concepts of reciprocity and patronage: “If I 
  share my food with you during this time of want, you ought to do a favor for me later.” 
  In their place exists a network of threats, expressed with a richly nuanced vocabulary of 
  abuse. Traditional Chauchua relationships do not include amity, only favorite slaves. Most 
  notably, even familial amity emerged as a cultural trait only with the influence of surrounding 
  cultures. By strictly Chauchua tradition, kindness is seen as a perversion. Even the weak 
  currying favor from the strong is an alien concept, since it’s presumed that the strong simply 
  take what they want without waiting for it to be offered. By tradition, weak Chauchua are 
  abused as a matter of course by strong Chauchua, in ever-shifting patterns of allegiance and 
  relative status. At the top are malevolent deities, who are owed not reverence or loyalty, but 
  terrified obedience. Finally, we examine ways in which the Chauchua struggle for cultural 
  identity created an imperative to dominate, betray, and manipulate outsiders, an expectation 
  often expressed in keen attention to the “weaknesses” of compassion-based cultures.
  mysterious active ingredient accumulates in the brain. It 
  does not dissolve.
  The DEA’s files purport to include chemical examina-
  tions of Reverb from the Nineties, but those examinations 
  went missing over the years. 
  If the Agents ask their case officer, the Program can 
  provide an old chemical analysis of Reverb, delivered via 
  old-fashioned handoff at a busy park. The case officer says 
  to bring a brown leather briefcase to swap at a park bench. 
  The report was stolen from the DEA in the early 2000s. It 
  matches the discoveries Agents could make for themselves, 
  but Reverb in those days included no MDMA.
  Tcho-Tcho Interviews
  The Tcho-Tcho community is embedded in the city’s larger 
  Southeast Asian neighborhoods. Talking to Tcho-Tchos, 
  the Agents can learn about Reverb’s source in Liao. That 
  requires a careful, respectful approach and access to one or 
  more  appropriate skill at 40% or higher: Foreign Language 
  (Cambodian, Chinese, Tcho-Tcho, or Vietnamese), Anthro-
  pology, or Occult. 
  The Tcho-Tcho community is insular. They expect 
  outsiders to focus on the cannibalism and rape that appear 
  in anthropological studies of their history, and have no

  she senses that the Agents are not being truthful about 
  their intentions, her people launch an investigation of 
  the Agents that may lead to dire complications after this 
  scenario. 
  About Liao
  If the Tcho-Tcho conversations go well, the Agents can learn 
  the following:
   
  » Reverb contains traces of Liao, the “black lotus,” 
  a very rare and sacred flower. In a painting of the 
  flower—in the hands of a bizarre god called Shuko-
  ran, with midnight-black skin and an elephant-trunk 
  face—it looks something like the Brahma Kamal 
  lotus, but deep purple.
   
  » Liao comes from the Himalayas. It is named for 
  a mythical Chinese alchemist who is said to have 
  discovered its powers.
   
  » Liao has been sacred to the Tcho-Tchos since time 
  immemorial. It is used in ceremonies to contact the 
  gods and see visions of the past and future.
   
  » Mixing Liao into a common street drug was sacri-
  legious 20 years ago and is sacrilegious today. It’s 
  good that Reverb went away all those years ago.
   
  » Consuming Liao in the wrong amounts risks 
  insanity. 
  reason to indulge that interest. Agents have to overcome 
  their suspicions. The Tcho-Tchos most willing to talk to 
  the Agents are the ones most interested in learning more 
  about them—especially if they sense that the Agents are 
  aware of the unnatural. They want to turn their interviews 
  into later access. 
  INFORMAL MEETINGS: Approaching the Tcho-Tcho com-
  munity informally, Agents might meet grocer Huo Zhang, 
  restauranteur Chey Thuy, or tea-shop owner Tran Van 
  Giap. They are friendly and inquisitive, but strive to learn 
  more about the Agents than the Agents learn about them. 
  They offer tea and snacks, including stir-fried vegetables 
  with a thick, creamy sauce that has a hot, peppery after-
  taste. They call it pork bon dzhow: pork ganglia paste, a 
  delicacy.
  THE CAAA: The Agents might contact the Chauch-
  ua-American Advocacy Alliance for background on Tcho-
  Tcho culture. The director is Trang Duc Bian, a retired 
  physician in her sixties, who was born in Vietnam and 
  gained American citizenship after her family fled for the 
  U.S. Dr. Bian is a close colleague of CAAA founder Cho 
  Chu-tsao, and a dedicated member of Cho’s Shukoran 
  cult. She reports all interesting contacts with outsiders to 
  Cho and the rest of the CAAA board. Dr. Bian is friendly, 
  hospitable, canny, and thorough. She offers her business 
  card to each Agent and expects theirs in return. Her office 
  is wired for video and sound and records the meeting. If

  the agents can use Law or Bureaucracy to assert DEA or 
  FBI jurisdiction over the case and ask for the suspect to be 
  handed over. 
  On the Streets
  Guided by a local expert like High Sally, the Agents could 
  find and try to grab Lucien “Bad Luke” Riggs on the street. 
  Done clumsily, that could easily become a shootout unless 
  the Agents are obviously police making an arrest. Riggs 
  usually is flanked by three or four friends, one or two with 
  pistols.
  A Name
  Persuade can convince Riggs or Brown to talk about the 
  source, if the agents apply the right leverage. Emphasizing 
  the risk of sudden disappearance and the promise of pro-
  tection would do it. The dealer says the source is Spider J, a 
  black man in his 30s. That’s the only name he knows. 
  Interference
  If the Handler wants to make things tougher, the Agents 
  could run afoul of rival gangs who want Reverb’s source for 
  their own purposes, police trying to do right or do wrong, 
  or a community reporter chasing the story of Reverb’s 
  resurgence.
  Afterward
  A few hours after meeting with the Agents, the dealer van-
  ishes from a locked holding cell or a bedroom, screaming, 
  every surface marred with gouges and scratches with no 
  trace evidence or blood left behind.
  The Source
  The agents can get some information about Spider J from 
  the local drug cops and DEA task force: Jacob Silas Sim-
  mons, black male, age 32, U.S. Army veteran, former con-
  tractor with the heavily militarized security firm Academi 
  (formerly Blackwater), no employment record in the last 
  two years, no fixed address. He has family in town but sees 
  them infrequently.
  Simmons’ army records indicate two tours in Afghani-
  stan. He was court-martialed in Afghanistan for suspicion 
  On that last point, an Agent with HUMINT 40% or 
  higher recognizes that the interview subject is withholding 
  something worse, something more frightening than mere 
  insanity. Further details can be gotten if the Agents treated 
  the assertions of Liao’s sacredness with respect. The sub-
  ject says taking too much Liao, or exploring its revelations 
  too deeply, risks losing oneself to hungry spirits. The Tcho-
  Tcho uses an old term from Sanskrit, preta, indicating a 
  malevolent ghost from Buddhist and Taoist traditions. But 
  an Agent with HUMINT, Occult, or a Southeast Asian 
  language at 60% or better discerns something else. The 
  phrasing and tone of voice indicate a malevolent spirit, 
  but not a human soul. The only way to divert the preta is 
  to meditate upon a wholly empty void or upon a perfect 
  sphere, things that confuse and calm the spirit. It helps 
  to smoke a very small dose of Liao, and to beg the fore-
  bearance of Shukoran, the hungry god who watches the 
  paths. SAN loss for Agents who take this seriously: 0/1. 
  The Tcho-Tcho offers no Liao to outsiders, but especially 
  stealthy Agents could find and steal some by succeeding at 
  both Stealth and Search rolls.
  Dealers
  To find the source of Reverb, the Agents have to talk to the 
  remaining dealers. The DEA files can indicate a few of the 
  network’s dealers who haven’t yet vanished and might be 
  involved with Reverb. With Criminology and some leg-
  work, they can get confirmation from a user who is tied to 
  the streets but doesn’t mind talking to investigators: Sally 
  “High Sally” Francis, so called because she’s fair-skinned, not 
  because she’s high, though she usually is. 
  Sally points to two dealers: Rufus LaRoyal Brown, 
  aka “Roofie,” and Lucien “Bad Luke” Riggs. Brown is in 
  a police station, under arrest and being interrogated on a 
  heroin charge. Riggs is at large.
  At the Station
  The Agents must use Persuade to convince the police to let 
  them interview Rufus Brown. A believable justification and 
  a Charisma test can get the cops to obtain specific infor-
  mation on the Agents’ behalf, but the cops don’t have the 
  leverage to make the dealer talk about Reverb’s source. Or

  overlooking a cluttered alley several stories below. The lap-
  top that stored video feeds from his cameras is gone.
  The Agents have a short window in which to interview 
  Spider J. No more than an hour; maybe only a few min-
  utes. The exact amount of time is up to the Handler. The 
  more efficient their investigation leading here, the more 
  time they have.
  Spider can tell the Agents the following, depending on 
  how much time they have and what questions they ask.
   
  » What Liao is, and what it does in Reverb.
   
  » At first he says “she” told him to take Liao, a lot of 
  it. But he can’t remember who or why, and then he 
  forgets that anyone told him to do it at all. 
   
  » Spider got Liao drug from connections in Afghan-
  istan. Tcho-Tcho elders controlled access to it and 
  forbade exporting it, but Spider helped make sure 
  they all died in a drone strike. The youth of their 
  tribe were happier to trade. 
   
  » Spider found the equipment to mix Liao into 
  enough Reverb to establish a new market, and he 
  added MDMA to punch it up. It was an ambitious 
  move. 
   
  » He has purer Liao not yet cut for the street. He’s 
  surprised to learn that there’s none in his room.
   
  » Spider did not tell his superiors in the network 
  about bringing Reverb back and amping it up with 
  MDMA. He figured that if it was a hit, he could 
  bring it in as a success. But when they found out, 
  they started scaring his dealers and eventually came 
  for him. He is distressed to realize he cannot remem-
  ber a thing about anyone from the network.
  The Footage
  The missing laptop is in the alley beneath Spider’s apart-
  ment. The woman who convinced Spider to overdose on 
  Liao couldn’t be bothered to carry the thing around. She 
  threw it out the window and it smashed to pieces. An Agent 
  with Search 40% or higher could find its pieces. 
  An Agent with Computer Science or a relevant Craft 
  at 60% or higher could repair it enough to review footage. 
  One segment shows an unknown woman entering Spider’s 
  apartment earlier that day, walking into the building past 
  of smuggling, but the charges did not stick and he received 
  an honorable discharge.
  Simmons appears in the files whose audit launched 
  this whole investigation, one rank up from the dealers 
  seemingly at risk of going missing—a “supervisor,” you 
  might say.
  Academi reps decline to say a single thing about his 
  employment or whether he was in fact employed with 
  them at all. A military character who talks to an Academi 
  rep off the record can get information with Charisma 13 
  or better. Reduce the Charisma requirement by 3 for an 
  officer and by 3 for special-operations experience. The 
  rep says Simmons worked three assignments in Afghani-
  stan and was busted twice for taking unauthorized trips 
  in country to meet with natives. Some suspected he was 
  involved with drugs. The company did not make that ac-
  cusation officially but declined his application for a fourth 
  contract.
  Finding Spider
  Local cops can help the agents track down Spider J, unless 
  the agents alienated the police earlier. If that’s the case, the 
  agents will have to get creative. They could recruit a local 
  informant who knows everyone (High Sally would do it), if 
  they put out some money and say they’re willing to turn a 
  blind eye toward what the money gets used for.
  Spider J stays at the Excelsior Hotel, in a room that’s 
  in the name of a girlfriend (Tanyika Taasa Tillerson, unem-
  ployed, supported by boyfriends like Spider) but paid for 
  with his cash. He keeps store-bought video cameras, posi-
  tioned discreetly and connected to a computer and screens 
  in his room by wifi, as a cheap security system. They 
  watch the hotel’s entrances, the elevators and hallway on 
  his floor, and the fire escape on his floor. The girlfriend 
  comes and goes. 
  The Agents can easily learn that Spider is alert, athletic, 
  armed, and violent. Catching him without getting anyone 
  hurt will require forethought, stealth, and decisive action.
  The Room
  But as it turns out, Spider is home and is in no position 
  to fight or flee. His glassy eyes and the residue in his pipe 
  indicate he’s dosed himself with Liao. A window is open,

  If the Agents fail to stop the manifestation, a Hound 
  of the Angles emerges from the corners of Spider’s eyes 
  and grows, looming over him and the Agents. (See THE 
  HOUND OF THE ANGLES on page 10.) 
  The SAN loss may well be catastrophic. Agents who 
  go temporarily insane find their understanding of physics 
  and spirituality completely shattered. Spider was seeing 
  things that truly happened. His consciousness really was 
  going back in time, back to when the universe was new—
  and found that the universe itself was alive with inhuman 
  evil. An insane Agent gains 5% in the Unnatural skill, or 
  adds 1D6% if the Agent has already gained Unnatural 
  from an insane insight before.
  The Hound bloodily destroys Spider, shredding 
  the very space-time that his shape occupies. (SAN loss: 
  1/1D6.) If an Agent interferes with it, or if one of them 
  is on a dose of Reverb and Liao and therefore catches its 
  interest, it attacks that Agent, too. But it does not pursue 
  them, as long as it has not finished consuming Spider. It 
  vanishes with the remains of its prey into the angles, leav-
  ing a wrecked room but no biological trace of its victims.
  Stopping the Hound
  The Agents can stop that from happening by killing the 
  dealer or rendering him unconscious. 
  They can escape by leaving it to devour Spider. Unfor-
  tunately, it becomes more attuned to this time and place, 
  and hunts more Reverb users until the supply dries up and 
  the incidents cease.
  If they begin during Spider’s trip, and they got instruc-
  tions from the Tcho-Tchos, they can attempt to stop the 
  Hound’s manifestation. The Agents must meditate upon a 
  wholly empty void or upon a perfect sphere. After they be-
  gin, ask each player to write down what his or her Agent 
  is meditating upon or thinking about. Next, each should 
  make a POW test. An Agent who has a well-established 
  history of meditation, or who has mastered any unnatural 
  rituals, gets a +20% bonus. If all are meditating on the 
  same thing—all the void, or all the sphere—use their best 
  roll and ignore the rest. If any meditate upon different 
  things, use their worst roll and ignore the rest. Oppose the 
  Agents’ result with the Hound’s POW test. If the Agents 
  win, the Hound does not emerge into the wider world.
  people who explicitly said they never saw her. (SAN loss: 
  0/1.) In the grainy footage, the woman looks Hispanic or 
  mixed-race, in her 30s or 40s, dressed professionally. Her 
  image does not come up in any facial-recognition database. 
  No one in the building or nearby remembers her. 
  For now, this is a dead end, intended to show that 
  Spider was involved in something much more dangerous 
  than he knew. Later, it could lead the Agents deep into the 
  occult underworld. The woman was several ranks above 
  Spider in the network. A longtime ally of Cho Chu-tsao, 
  she is a sorcerer skilled at manipulating behavior, mem-
  ories, and perceptions. She persuaded Spider to overdose, 
  altered his memories, and took the remainder of his supply 
  of Liao. Long ago, in New York, the cultists of the Fate 
  called her the Lord of Truth.
  The Hound
  As the Liao takes hold, Spider raves about things seen in the

  » A choice moment from Delta Green’s history.
   
  » A Mayan or Aztec pyramid bathed in blood. 
   
  » A hardy people crossing a landscape of ice. 
   
  » A reptilian creature standing like a man, in elaborate 
  silk robes, in some kind of laboratory, surrounded 
  by implements of glass and metal. Through a tall 
  window, a dinosaur scavenges in the jungle outside. 
  This is obviously long before humanity. If it’s not a 
  hallucination, then through whose eyes or senses is 
  he seeing?
   
  » Then he’s leapt too far back. He can barely con-
  ceptualize what he sees, let alone describe it. Lights 
  and energies pulsing, intersecting, full of malice. He 
  becomes terrified. He’s looking at the essence of evil.
   
  » Two surfaces converge. Something comes out of the 
  line where they meet. He can’t describe it. It’s like all 
  the evil of the universe, concentrated and alive—and 
  hungry.
   
  » He realizes with horror that the thing has sensed 
  him. He shrieks. He begs to know why he can’t 
  come back to himself. 
   
  »“Oh God, it’s in my brain!”

  If they obtained Liao, the Agents may attempt to 
  follow a Tcho-Tcho tip to take a small dose. Unless the 
  Handler decides the recipe is in an old Delta Green report, 
  mixing Liao correctly requires having gotten instruc-
  tions from a Tcho-Tcho interview subject, and then an 
  Agent succeeding at a Pharmacy test. (A failed roll leaves 
  the Agents intoxicated, with a –20% penalty to all tests, 
  including Sanity; a fumble means any Agent who fails 
  a CON test is pulled into Spider’s disastrous trip.) Each 
  Agent under the influence of a correct dose gains a +40% 
  bonus to the POW test.
  If the Agents understand that they stopped the 
  Hound’s manifestation, each gains 1D6 SAN. 
  Whether the Hound comes for Spider at some later 
  date, and when, is up to the Handler.

  CURVED SPACE: Exposure to large areas composed of 
  curves, spheres or circular surfaces causes the hound’s 
  “swarm” of shards to lose coherency. The hound is well 
  aware of this weakness, and does its best to avoid and flee 
  such areas. Each turn of exposure to such a space causes 
  the hound 1D6 damage. If it reduced to 0 HP from exposure 
  to curves, the hound disintegrates and seems to fold out of 
  three-dimensional space (likely returning it to its place of 
  origin).
  INCONSTANT FORM: The hound can fold, change, stretch, 
  extend and warp its form in amazing ways, altering its size 
  as needed from moment to moment. It can effectively attack 
  anyone within 10 meters by directing its form to a new 
  location. Because it has no “body” and is instead composed 
  of a thousand swirling, reflective shards of space-time, the 
  hound is immune to all attacks except hypergeometry.
  INHUMAN STATS: A test of a stat with a score of 20 or 
  higher is a critical success on any roll up to the stat’s score, 
  and on any roll of matching digits except 100, which fumbles.
  SHARD SWEEP: The hound unleashes two “limbs” composed 
  of shards, peppering a target with 2D6 damage. It ignores 
  body armor but can be blocked by cover. 
  SHARD SWARM: The hound engulfs the victim in a swirling 
  mass of shards, rendering the target down to a bloody mess 
  with a Lethality attack of 10%. It ignores body armor but can 
  be blocked by cover.
  SAN LOSS: 1D6/1D20.
  The Hound of the Angles
  This terrifying, geometric entity boils into our four dimen-
  sions from sharp angles and edges. Its body is composed of 
  a thousand shards of glittering, razor-sharp fragments of 
  space-time which move and reform in the vaguest outline 
  of a quadrupedal predator. It hunts in a similar manner to a 
  dog, wolf or tiger, stalking prey, taking it down, and rending 
  it to death, leaving behind only a bloody mess before van-
  ishing with its victim’s remains into some inscrutable corner 
  of reality.

  ARMOR: See INCONSTANT FORM.
  SKILLS: Alertness 90%, Angular Apport 75%, Stealth 50%,

  SWEEP).
   
  Shard Swarm 70%, Lethality 10% (see SHARD SWARM).
  ANGULAR APPORT: On a successful Angular Apport skill 
  roll, the hound can leap into or emerge from any sharp, 
  physical angle—a corner of a room, the lip of a table, or 
  even the hinge on a pair of glasses—effectively teleporting 
  between those two points instantly no matter the distance. In 
  this manner they pursue their prey, so outrunning them is an 
  unlikely outcome, no matter the speed of escape.
