TEXT: The Unmasking 
   
  This adventure is an attempt at a sequel to my favorite scenario “The Evil Stars” by Keith Herber 
  from Cthulhu Now. I’ve also Delta Green’d it and reconciled the old Hastur references to the John Tynes 
  version of the Hastur Mythos from Countdown. 
   
  Background 
  In the early 1990’s the rock band ‘God’s Lost Children’ lead by Brian Lochnar, employed the southern 
  Florida motorcycle gang ‘Satan’s Sadists’ as security. Lochnar was a cultist worshipping Hastur. The Leader 
  of Satan’s Sadists, William “Billy” Masters, was his right hand man, assisting in the preparation of a complex 
  plot to bring He Who Is Not To Be Named into our world. When Lochnar sacrificed Billy’s girlfriend Star to 
  the great old one, Billy put two .357 magnum rounds in his face just as federal agents closed in. Billy, 
  distraught over the loss of his girlfriend, went peacefully and plea bargained to a lesser charge of 
  manslaughter and served 10 yrs. in Florida State Penitentiary. Billy spent his time studying mysticism and 
  chemistry through the prison library and interlibrary loan system, while harnessing his devotion to Hastur the 
  Unspeakable. 
  He was released in 2003 and dropped out of sight shortly thereafter. During a chance meeting at a gun show in 
  northern California, Billy met Rex Hagans, leader of the Army of the Yellow Sign, a militia / cult based in 
  Montana. Billy spent the next few years studying with Rex and the Army of the Yellow Sign at their 
  compound in Montana. After learning all he could from them, he decided to leave for Southern California. 
  That is where Billy began building the motorcycle gang that would become known as the Strangers. 
  The Strangers operate just like any other motorcycle gang, with new members or ‘prospects’ only allowed to 
  wear the bottom 3rd of the back patch until they are voted in by majority of the ‘full patch’ members, or 
  members who have been in the gang long enough to have earned the lower patch which has the territory the 
  gang controls, the upper patch, with the name of the gang on it, and the large insignia patch in the center. Of 
  the full patch members there are the executive officers, with rank insignia designating them as President, VP, 
  Treasurer or Sergeant at arms. Billy is the President of the Strangers; his executive officers form the inner 
  circle of the gang and are all devoted cultists of Hastur. Billy has a new plan to bring Hastur into this world 
  and is using the power of the Strangers to make it happen. 
  During his time with Rex Hagan’s Army of the Yellow Sign, Billy learned of a poppy native to Carcosa, 
  homeland of Hastur and the King in Yellow, called Melonia, a powerful hallucinogen that opens the users 
  mind to the influence of Hastur. Melonia poppies are harvested in Carcosa by the Tcho-Tcho peoples and 
  brought to the Plateau of Leng. From there, they smuggle it to Malaysia. Billy has the Melonia shipped from 
  Malaysia into Long Beach Harbor in Southern California via Tiger Transit. Mixing Melonia with a very low 
  grade Mexican Black Tar Heroin (tracking the origins of the heroin purchase eventually leads to the Disciples 
  of the Worm), Billy had found the key to converting an army of unknowing sacrifices to He Who Shall Not 
  Be Named. 
  Using ruthless violence and his summon / bind Byakhee spell to get rid of anyone that opposed him, Billy 
  quickly began growing the territory of the Strangers and eliminating opposing gangs and drug dealers. It 
  didn’t take long for word to spread among the criminal community that the Strangers were not to be messed 
  with. 
  Billy and the Strangers moved into the desert of Southern California in the foothills of the San Bernardino 
  Mountains, a place known for its clandestine drug labs and wide open spaces. The current biker gang claiming 
  this as their turf, the Monarchs stood little chance against Billy and his Strangers. They quickly took over the 
  meth labs that dot the desert landscape and converted them to make Billy’s new drug, known only as 
  ‘Yellow’. 
  The gang owns a warehouse where they receive shipments of the Melonia they need to make Yellow. These 
  shipments come by delivery truck, are unloaded, separated, and delivered to the various labs scattered 
  throughout the desert. The labs then turn the raw Melonia into Yellow, a simple yellow powder, similar in 
  appearance to finely ground cornmeal, by chemically processing the Melonia the way opium is turned into 
  heroin, and then adding small doses of black tar heroin. The finished product is then handed over to various 
  
  dealers who sell it on the streets for a modest markup. The current street price of Yellow is around $10 per 
  dose (1/10 gram). The effects are very similar to most mild hallucinogens, with underlying heroin effects 
  including mild euphoria, feeling of separation from the body, with common hallucinations including Victorian 
  cityscape, mist covered lake, labyrinth, impossible architecture, inverted night sky with two moons and a 
  royal palace in the distance. 
  Billy has purchased a large plot of desert in an area of  Lucerne Valley known as Anderson Dry Lake bed, a 
  naturally V shaped valley surrounded on three sides by rocky hills, where he has begun construction of the 
  nine monoliths needed to summon Hastur. Members of the Strangers can be followed to this location and seen 
  working on and guarding the monoliths at all hours. Billy personally oversees construction, barking orders 
  and rushing construction, as he needs to have everything ready before Feb 2nd. The Agents are called in early 
  Jan. leaving less than a month of investigation. 
  Investigator Information 
  The investigators, all of whom should be Delta Green agents, are summoned to the DEA field office in 
  Riverside, Ca. All agents should either be DEA or FBI agents or they will be provided with cover as such by 
  A cell. The agents are met by DEA Agent 
  Matt Webster, a DG friendly who was able to identify traces of black tar heroin, but a 2nd unknown 
  component and an unusual yellow symbol on the baggie caused Webster to alert A cell. Agent Webster 
  informs the agents of the new drug that was brought to them by the local sheriff’s dept. drug task force for 
  identification. The deputy says it is known only as ‘yellow’ and its very cheap, very powerful, and very 
  addictive. The deputy that brought it in said that the sample was seized during a routine traffic stop of a biker 
  named ‘Junior’ a few days ago in Victorville and is being held in the Victorville Sheriff’s office. The search 
  turned up only a small sample, less than 1/10 gram, and the DEA hopes more can be learned from a bigger 
  sample.

  Junior is being held at the Victorville Sheriff’s department office and is available for questioning, however 
  very little can be learned from him. Junior (Mike Reed jr.) is a 42 yr. old 6’ tall 190 lb. Caucasian man with 
  tattoos over most of his body. Juniors possessions at the time of the arrest include his leather vest with a large 
  yellow symbol (the Yellow Sign) embroidered on the back. Junior tested positive for low doses of heroin in 
  his system at the time of his arrest 3 days ago. Interviewing Junior reveals that he is completely out of touch 
  with reality, mumbling about the return of the Last King and Lake Hali. He says that the truth will be revealed 
  when all the masks are removed at the great ball this Candlemas, the Palace is being rebuilt, and the gate will 
  be opened for the phantom stranger. He will give only cryptic answers. Junior has made the Unspeakable 
  Promise and has a 2% chance of transforming into the Unspeakable Possessor while Aldebraan is in the night 
  sky. 
  Successful mythos roll determines the symbol to be the yellow sign, library search will point to the King in 
  Yellow play, in English, Nearest available copy at the UCLA library, and the Turner Codex, in English, at the 
  UC Berkeley library, both in the rare books departments and only viewable in the library under supervision of 
  the librarian. FBI cross reference of the King in Yellow and Turner Codex reveals that a copy of each is listed 
  among the items confiscated during the Feb 1988 investigation of the death of GLC lead singer Brian 
  Lochnar.

  Investigating local bikers will lead the characters to the Screaming Chicken Saloon, local biker hangout and 
  neutral safe zone between members of the various area biker gangs. This bar is as stereotypical as they come. 
  The bikes out front and the outside appearance of this run down dive bar make sure that everyone approaching 
  knows exactly what they are in for. Open from 9am till 2am local seedy characters can be found here at any 
  time of day or night, sitting at the bar, watching sports, playing pool and other, less wholesome, activities. The 
  Bartenders are the only authority in this place, badges, ranks and affiliations are thrown out the window here, 
  like so many past patrons. Head bartender Ruby works Thursday thru Sunday, 6pm to closing. Ruby is in her 
  early 40’s but years of hard living have taken their toll. Any investigators who look out of place will be met 
  with resistance as tight lips are the rule here. If caught alone, Ruby can be persuaded to talk with offers of 
  $100 or more, substantial quantities of cocaine or successful fast talk, credit rating or persuade rolls. What 
  Ruby knows: Junior is a local who used to run with a gang known as the Monarchs and recently joined “the 
  Strangers” she doesn’t know much about the Strangers, other than they don’t hang out at the bar, they wear a 
  strange yellow symbol on their vests, and no one talks about them. If asked about ‘Yellow’, Ruby will say that 
  it first started making the rounds about 6 months ago, some kind of trip drug that’s dirt cheap, and getting real 
  popular. In fact, Junior started fooling with it before he joined the Strangers and the same for several other 
  bikers who have recently switched teams. Ruby has never tried Yellow, as she had a bad trip on LSD in the 
  late 70’s, and hasn’t touched hallucinogens since. Big Ed of the Monarchs might know more, and he might be 
  found working security on any night of the week at Art’s Place, a Monarchs controlled bar in Apple Valley. 
  Beyond that, Ruby knows nothing else of use. 
  Big Ed is 5’9” 350lb Hispanic, and loyal member of the Monarchs. Eduardo Ramirez is his real name, and he 
  is on probation from an assault charge 2 years ago. Ed recently had a baby with his long term girlfriend Maria 
  and that is his only weakness. One of the terms of his probation was that he not associate with any other 
  known felons, a quick glance around the bar will turn up 3 violations within arms distance. Ed has been 
  working very hard to clean up his act since the birth of his baby, and will cooperate grudgingly if convinced 
  he might go back to jail. Big Ed knew Junior well, and knows that Yellow was in fact the catalyst that led to 
  his leaving the Monarchs. Yellow turned up the area a few months ago and became very popular very fast. 
  Junior tried it at a party, and began to change very quickly. He became obsessed, when he wasn’t high on 
  Yellow, he was trying to get more, or talking about Lake Hali and the Last King and other such nonesuch. Not 
  long after, he left the Monarchs for the Strangers. When the Monarchs decided they did not appreciate this 
  intrusion on their territory and income, they found out all about the Strangers. What exactly happened, Ed will 
  not say. Ed knows only where the Strangers clubhouse is, an old warehouse in Adelanto, but he will deny ever 
  talking to the investigators.

  The following are real world locations of branch offices for various federal agencies in the area. Each of these 
  offices are approx. 45 minute drive away from the locations listed in the adventure, while temporary 
  command centers could easily be set up at any of the San Bernardino County Sheriff’s offices in the area. 
  Victorville California is the main city of the Victor Valley in the Mojave Desert of north-eastern San 
  Bernardino County. The Victor Valley is sprawling desert community located along Interstate 15 between San 
  Bernardino and Barstow. The climate of the area is usually cold and rainy with potentially freezing 
  temperatures and occasional snow between December and early March. The Landscape is a vast sea of 
  varying shades of brown, with rocky hills and small mountains in most every direction, and the only greenery 
  being found in the newly arrived housing developments near the highway. With Victorville being in the 
  center, Apple and Lucerne Valleys are to the eastern edge of area, known for the extremely isolated and 
  sparse population, abandoned homesteads and the high number of clandestine drug labs dotting the landscape. 
  To the west are Phelan and Adelanto, with tightly clustered areas of mass housing surrounded by sprawling 
  industrial areas. 
  
  The Strangers Clubhouse 
  The small warehouse in Adelanto is located in a mostly abandoned industrial neighborhood and other than the 
  occasional delivery; it would appear to be abandoned as well. The property owner on file is George Spelvin. 
  The building is a small square windowless steel warehouse with one large roll up door in the front and one 
  normal door on the side of the building. A 6’ chain link fence surrounds the cracked asphalt covered yard and 
  protects passersby from the 3 large Pit bulls who patrol the property night and day. There is a 5% chance that 
  Billy will be at the warehouse at any given time, and a 10% chance he will be among the bikers that show up 
  at night 
  A stakeout will give a 40% chance on any night of 2d4 motorcycles showing up late in the evening, go in 
  through the gate, locking it behind them, then into the warehouse via the roll up door, locking their 
  motorcycles and themselves inside till morning when the delivery arrives. Once a week an unmarked delivery 
  van is met at the gate by the bikers, let in and backed up to the roll up door, and unloaded. Each delivery is the 
  same, 2 pallets of unmarked cardboard boxes. Running the plates of the truck shows it’s registered to George 
  Spelvin, the address is the same as the warehouse. The driver is different each time and knows nothing of the 
  contents or the recipients. He speaks little English and will say he was paid $100 by some members of the 
  Strangers a few days ago to drive this truck from Adelanto to the Long Beach port and back to the warehouse. 
  There is nothing else in the truck if stopped after leaving the warehouse. If stopped on the way to the 
  warehouse it will have only the 2 pallets of unmarked cardboard boxes. In these boxes are what appear to be 
  dried gooseberries, small greenish yellow orbs about the size of a grape. These berries are Melonia; they grow 
  only in Carcossa and are unidentifiable by any chemist or botanist. Following the truck after the delivery leads 
  to a parking lot in Victorville, where the driver will park it, locking the key inside, and walk home. Several 
  days later, a different driver will get in the truck and drive it to a port in Long Beach where it will pick up 2 
  more pallets of Melonia and repeat the process. Once the truck has been stopped, or once the Strangers know 
  they are being watched, the deliveries will stop coming to the warehouse and the truck will be parked and 
  abandoned. 
  After the delivery truck drops the pallets of Melonia at the warehouse and leaves, the bikers inside sort out the 
  different packages and leave with saddle bags full at around 11pm. They will each go to different locations 
  with their individual parcels. Various clandestine drug labs throughout the desert, mobile homes on large, 
  isolated and fenced desert lots, all with dogs, geese and peacocks patrolling the property, each having 2d6 
  bikers and amateur chemists on the property. If the investigators attempt to break into the lab without help 
  from the bomb squad or other experts, they will need successful spot hidden rolls while entering to see the 
  traps before setting them off, and then a successful explosives skill roll to disarm them before triggering the 
  explosive chemicals that quickly fill the cramped mobile home and explode causing burn damage and hazmat 
  exposure. Inside these labs Melonia is refined using a complex and dangerous chemical process and mixed 
  with small amounts of very low grade heroin, dried, crushed into powder and packaged in individual 1/10 
  gram baggies with a small yellow sign embossed on them. 
  Inside the Warehouse 
  This building is approx. 2000 sq. ft. of open rectangular warehouse space with a roll up bay door on the east 
  wall, and the main entrance on the north wall. Inside the walls are corrugated steel and the floor is plain 
  concrete. The main warehouse area is a cluttered mess of empty boxes, beer cans and motorcycle parts. The 
  south eastern corner of the building is home to the small private office. The office is a filthy mess of empty 
  boxes, pornography, trash and broken grease stained furniture. A pile of mail opened and unopened sits on top 
  of a 19” TV/VCR in the corner of the room. The mail is all addressed to George Spelvin, all with the address 
  of the warehouse. Some of the mail is registration info for the delivery van, receipts from local concrete 
  delivery company, lease and insurance info for the warehouse, and then there is mail from the federal bureau 
  of land management regarding the purchase of 20 acres of land in nearby Lucerne Valley on Camp Rock rd., 
  for $45000, paid in full. The receipts indicate that 9 different concrete delivery trucks are scheduled to deliver 
  10 cubic yards of concrete each, every other day from January 6th to January 22nd, to a location on Camp Rock 
  rd.  in Lucerne Valley, for just over $1000 per delivery.

  Following the Bikers 
  Successfully trailing any member of the gang has a 20% chance of being lead to Anderson Dry Lake bed. 
  They follow hwy. 18 for about 35 miles to Camp Rock rd. and turn left (north) and then travel approx. 5 miles 
  out into the open desert where the road cuts into a small valley and becomes a dirt road and turns sharp to the 
  right following the side of a large dry lake bed. At this point safely following the bikers undetected by car will 
  be practically impossible since this trail goes another 5 miles around the outside of Anderson Dry Lake and 
  ends in a V-shaped valley where the bulk of the Strangers are camping, partying and constructing the 10’ tall, 
  5’ wide and 5’ thick monoliths in a large V within the valley, surrounding the dry lake bed on 3 sides. 
  Every other day, starting Jan. 6th, a concrete truck is scheduled to deliver 103 yards of concrete (a full mixer 
  truck) to Anderson Dry Lake at 9am. The truck will be met at the end of the pavement by one of the members 
  on his motorcycle and escorted to whichever one of the large wooden forms in the lake bed are supposed to be 
  filled, alternating from the outside of the V-shape, left and right, until the final monolith form at the point of 
  the V on January 22nd. 
  Agents able to get a vantage point to watch the proceedings will see the gang members constructing forms or 
  assisting in the pouring of the concrete if a delivery is being made. It takes about 1 hour to empty the contents 
  of the concrete mixer in a monolith form, then the truck drives out the way it came, stopping briefly near the 
  edge of the valley to rinse out the truck and chute with the built in water hose. 
  At midnight after a concrete delivery, Billy will come out to the lakebed personally to perform the 
  consecration ceremony for the monolith. The whole gang will be there, and they will all be under the 
  influence of Yellow. Billy will then climb to the top of the scaffolding around the newest monolith and make 
  the necessary sacrifice to He Who Shall Not Be Named. 
  Anderson Dry Lake Bed 
  This large dry lake lies within a V shaped valley surrounded on three sides by jagged rocky hills. This lake 
  bed bears the scars of years of use by off roaders and camping with trails zigzagging across the valley floor. 
  The main trail cuts to the right from camp rock rd. and follows the southern edge of the valley between the 
  hills and the lake bed. There is absolutely no cover here and the hills are rocky and jagged. Nearly 4 miles in 
  and 3 miles across of flat, cracked dirt, broken only by the occasional small sagebrush shrub clinging to the 
  harsh almost alien landscape. Along the sides of the lakebed are the nine 10’ X 5’ X 5’ wooden forms in 
  various stages of construction depending on the date. From above the forms make a perfect V shape along the 
  borders of the lake within the confines of the small valley floor. The area within the valley is guarded by a 
  
  Byakhee summoned by Billy on January 6th and bound to protect the valley from anyone not wearing a yellow 
  sign until February 1st. 
   
  Taking ‘Yellow’ 
  Standard purchase = approx. $10 for 1/10 gram, or 100 mg, approx. 2-4 doses usually snorted, but may also 
  be smoked or injected. Effects are felt within seconds and last from 2 to 4 hours with a gradually increasing 
  sense of displacement, sometimes a floating or swimming feeling and a general euphoria. Users will see the 
  world around them ‘differently’ with buildings and environment looking Victorian / Edwardian, mist 
  blanketed lake, streets made of cobblestone with street lights replaced by gas lamps. Black stars dot the 
  eternally dismal grey sky and huge winged black beasts occasionally soar past the twin moons that illuminate 
  the strange dark city. All of this comes as if perfectly normal to anyone under the influence of Yellow and 
  only seem odd in retrospect. 1/1d4 san loss per use. Extended use will reveal more and more of Carcosa. 
  Deeper understanding of Hastur, the KiY, Yhtill and the masquerade ball, and a general feeling of 
  homesickness when not under the influence. Also, after one use of the drug, the yellow sign will swirl 
  whenever seen, sober or not. On Candlemas, when Billy begins the ceremony in the desert, anyone who has 
  ever taken a single dose of yellow, will be drawn to the location of the ceremony like a sirens song.

  Timeline of Events 
  January 4th – Junior arrested in Victorville 
  January 6th – First concrete delivery to Anderson dry lake for monolith creation 
  January 7th – Investigators arrive 
  January 8th – Second concrete delivery 
  January 10th – Third concrete delivery 
  January 12th – Fourth delivery 
  January 14th – Fifth delivery 
  January 16th – Sixth delivery 
  January 18th – Seventh delivery 
  January 20th – Eighth delivery 
  January 22nd – Ninth and final delivery 
  
  February 1st – Yellow users begin flocking to the lakebed, Masquerade ball begins at dusk 
  February 2nd – Billy summons Hastur 
  Finale 
  On February 1 anyone within 50 miles who have used Yellow will begin flocking to Anderson Dry Lakebed 
  by any means available. After sunset the area within the monoliths will be transformed into the royal ballroom 
  of Yhtill to all who have taken Yellow. The transformation will become increasingly real to the users as Billy 
  begins the Call Hastur spell which climaxes just after midnight when the spell is completed and, to the Yellow 
  users who are participating in Queen Cassilda’s masquerade ball, are instructed to remove their masks. 
  Anyone watching this who has not taken Yellow will be horrified to witness hundreds of hallucinating 
  attendees go from ballroom dancing to unheard music, then after a few moments of rapt attention to an unseen 
  speaker, they will begin calmly clawing at their own faces, attempting to remove their masks and reveal their 
  true identities. The victims / participants will take 4D4 damage as well as blood loss at the rate of 1 hit point 
  per minute. This scene will cost witnesses 1d6/1d20 san as the stars in the sky become inverted and Byakhee 
  screech and swoop through the air above. The area within the monoliths will slowly become permanently 
  transformed into a gate to Carcosa which will leak and overflow until it consumes our entire reality. 
  Conclusion 
  Stopping Billy from performing the final Free Hastur spell at midnight in the presence of the required 
  monoliths and appropriate number of sacrifices is all that the investigators need to do to prevent the 
  summoning. There are several paths to this end. 
  Destroying a monolith will require getting past the bikers and the Byakhee as well as explosives. If a monolith 
  or more are destroyed, Billy will attempt to rebuild them as quickly as possible, sparing no expense to erect 
  the replacements in time for the summoning. 
  Preventing Billy from attending the masquerade ball is the simplest answer, however, he will return to try 
  again next year if given the opportunity. Again, the bikers and Byakhee will not make this easy for the 
  players. 
  If the investigators succeed in stopping Billy they each receive 3d6 Sanity award.
