Slaughterhouse
By Flore
Introduction
Long-forgotten remnants of MAJESTIC's Project CORE have resurfaced in Muscatine County, Iowa. A black, metallic artifact was transferred to the local biotech firm New Harvest Biosciences (NHB). When the researchers activated it, the artifact began rewriting living tissue. Within days, three scientists underwent violent transformations.
Background
New Harvest Biosciences (NHB) is a small Muscatine biotech firm quietly owned through March Technologies subsidiaries. Four scientists—Morrow, Kaneko, Hume, and Voss—received the artifact from an unregistered MAJESTIC site. They activated it a week before the Agents arrived.
The Resonant Core
The artifact is a "Seed" of Shub-Niggurath, a dormant pattern meant to rewrite biological matter into new forms. It activates only through sustained exposure to multiple living organisms under stress. When this exposure breaks down, the Seed falls dormant, but not destroyed.
The Abominations
Through the transformation process of the Core, each scientist turned into grotesque animal-human hybrids based on the species they were researching.
Dr. Lila Morrow
Lead researcher in transplantation and regenerative biology using pigs. Her body became a massive, uncontrolled growth rooted in the NHB slaughterhouse.
Dr. Hana Kaneko
Studied prey-response behavior; twisted into a predatory, deer-like horror with elongated limbs and jagged bone ridges. Four days before Agents arrive, she killed Hume and fled into the woods near her home, now stalking the area at night.
Dr. Caleb Hume
Studied aggressive immune responses using bull genetics. Killed by Kaneko, his corpse continues mutating post-mortem into a brutish, horned mass.
Dr. Nathaniel Voss
Unaffected physically, he shielded himself during activation but suffered mental strain. He fled with the Resonant Core to his hunting cabin near Cedar Rapids, Iowa.
A Body in the Woods
On November 25, teenagers hiking Wildcat Den State Park found Hume's partially devoured corpse wedged between limestone outcrops. Police rule it an animal attack, citing deer tracks and rutting season.
Dr. Laurel Keene, Muscatine County's Medical Examiner and Delta Green friendly, notes early post-mortem morphological changes inconsistent with any known wildlife.
The Trucker's Sighting
That night, a trucker on New Era Road captured low-quality dashcam footage of a tall, gaunt, deer-like silhouette leaping across the road. Locals circulated it online as "Muscatine's Mothman."
Dr. Keene, reviewing this alongside Hume's autopsy, contacts Delta Green.
Briefing
Agents are summoned in Iowa City on November 27 for Operation HEADLIGHT. They are tasked with identifying and containing any possible unnatural threat while avoiding public awareness. They operate as FBI consultants or deputized federal officers. Share information from A BODY IN THE WOODS and THE TRUCKER'S SIGHTING.
Local Authorities
Agents primarily deal with Sheriff Elise Grant, who is blunt and eager to close the case as an animal attack, and Dr. Laurel Keene, who is cautious but cooperative.
Sheriff's Office
Grant is surprised and worried the FBI are visiting about this case. If the Agents can come up with a good enough reason for getting details into the case, she'll comply.
While photographs show that the body was in a gruesome and horrible state, the reports conclude it was an animal attack, possibly caused by deer. Grant notes that the body is currently at the ME's Office.
Hume's personal effects can be examined here, this includes his wallet, phone, and an encrypted flash drive.
The Phone
His phone is locked, but shows many missed calls and messages.
Agents able to extract the logs from the phone find a set of frantic texts from Nathaniel Voss in the 24 hours before Hume's death. Voss is extremely worried about Hume's state. The calls and messages stopped when Hume's death became public.
Agents that extract location history from the phone can find that Hume has been at KANEKO’S HOME, THE SLAUGHTERHOUSE, and VOSS’S HUNTING CABIN during the weeks before his death.
The Flash Drive
The encrypted drive contains fragmented research data and a corrupted video documenting a lab experiment spiraling out of control.
- CORE_01_READINGS: Instrument logs show escalating energy spikes around an unidentified artifact, ending with “Threshold crossed. Cannot stabilize.”
- OBSERVATION_NOTES: Scans of Hume's frantic notes describe abnormal tissue growth in Morrow, behavioral shifts in Kaneko, and increasing concern over “resonance effects.”
- ANOMALOUS_TISSUE: Microscopy images and partial DNA analyses reveal impossible hybridization and black resin secretion with no known biological markers.
- VOSS_CORRESPONDENCE: Unsent drafts to Voss warn that the project is dangerous, the team is changing, and that Kaneko may already have transformed.
- A corrupted 21-second video shows the artifact pulsing in a dark lab, something moving off-camera, and Hume whispering, "We're losing control," before the file fails.
Viewing the contents costs 1/1D6 SAN from the Unnatural.
Medical Examiner's Office
Dr. Laurel Keene has been the Medical Examiner for Muscatine County for 12 years. When the Agents meet her she's tense and tired. Hume's Body has been put in cold storage.
Hume's body is swollen and deformed, with thickened limbs, budding horns, and patches of skin stretched over emerging hooves. Keene is surprised the changes continue in cold storage. Viewing the body costs 0/1D4 SAN.
Agents can examine the body themselves or have Keene point out: ongoing tissue growth, unnatural bite and tear patterns, fractures consistent with predatory attacks rather than trampling, and black resin-like material in the wounds.
Keene notes the phone rang repeatedly, but she couldn't see who called; the personal effects are with the Sheriff.
Finally, Keene asks the Agents what to do with the body. She's worried about the continuous growths and what she saw on the dashcam video.
New Harvest Biosciences
Public records show a small staff, large facility, and minimal publications, unusual for a biotech firm. Corporate filings show that it is owned by March Technologies through a series of holding companies. These filings also show that NHB is the owner of a large industrial facility zoned as a slaughterhouse.
NHB Office
The modern facility is quiet, with minimal staff visible. Receptionist Tanya Rivera enforces strict access rules at the facility, but nothing regarding the Core research can be found here. Employees gossip about late-night lab work and their missing bosses but are cautious after hearing about Hume's death.
Investigating the Researchers
The four NHB scientists have sparse public records; LinkedIn shows past academic positions and specialties, but no recent publications. Social media suggests long lab hours. Public records on the three living NHB scientists indicate no leave, yet locals report they've been unusually absent.
Kaneko's home
Kaneko's home sits at the edge of woods and fields, giving her plenty of cover. Trails of broken branches, flattened vegetation, and clawed animal carcasses mark her hunting grounds. She prowls at night, moving erratically and striking quickly at anything she perceives as prey.
The house is disheveled, with overturned furniture, claw marks on walls, shredded curtains, and traces of blood and black resin.
Agents may encounter Kaneko stalking them around her home after dark.
Voss's Hunting Cabin
Voss's remote cabin is small and padlocked, deep in the woods near Cedar Rapids. Inside, the space is cluttered with half-packed gear, muddy boots, and scattered medical supplies.
Voss is inside, paranoid and jumpy, constantly scanning windows and the woods. He will not let the Agents come into his house and will resort to violence if push comes to shove. Agents that are able to calm Voss down can talk to him about what happened at the lab, and he can point them towards THE SLAUGHTERHOUSE and KANEKO’S HOME. Voss knows enough to recreate portions of the research, and his deteriorating mental state makes him an ongoing containment risk if not dealt with decisively. If Voss is neutralized, the same information can be gleaned from his notes.
The deactivated Resonant Core rests among the clutter, and his laptop and notes contain the same data as THE FLASH DRIVE.
The Slaughterhouse
The NHB-owned slaughterhouse sits on the outskirts of Muscatine County, appearing abandoned and decayed. The abandoned facility is a maze of rusted equipment, bloodstains, and deep claw marks.
The Hidden Lab
A reinforced trapdoor leads to a hidden lab strewn with shattered instruments and research notes on the Core's biological effects. Annotations reference additional MAJESTIC documents sent with the artifact, “resonance thresholds,” and “hybridization trials,” hinting that the Resonant Core is part of something far larger, older, and far more dangerous.
Encountering Dr. Morrow
Within the hidden lab, the grotesque form of Dr. Morrow lives. She is a massive, pulsating pig-human abomination. Her body sprawls across the floor in an ever-growing mass of flesh, bones, and organs. The air is thick with the stench of decay and black resin. Morrow thrashes violently, attacking anything nearby with surprising speed and strength. Agents must kill or contain her.
Resolution
Neutralizing Kaneko, Voss, and Morrow—and deciding the fate of the Resonant Core—is the operation's end goal. All evidence must be contained or erased to prevent further investigation or public awareness.
Agents gain 1D4 SAN for each abomination eliminated; additional SAN awards are at the Handler's discretion.
