Release [Chaosium] Miskatonic Monday - New Call of Cthulhu Releases from the Miskatonic Repository

Michael O'Brien

An eclectic mix of new Miskatonic Repository scenarios here, showing the versatility of the Call of Cthulhu RPG!


The Grindhouse: Volume 1
Alex Guillotte, Ian Christiansen ($2.95, 40 page PDF)

grindhouse [grahynd-hous] n. – A grindhouse or action house is an American slang term for a theatre that mainly shows low-budget horror, splatter and exploitation films for adults.

Friday Night Double Feature!

The Crimson King: This scenario takes place in the early 1980s. The characters have been invited to an exclusive nightclub that features early goth music with industrial and punk influences. Illicit drugs and overt sexuality are ubiquitous with the underground nightclubs of the time, and by all accounts The Court of the Crimson King is no exception.

Isle of the Damned: Set on a small island off the coast of Maine, this scenario takes place in the summer of 1974. A group of friends have rented a small vacation house with the intent of spending a week fishing, drinking, and maybe smoking a little weed. Things begin to go sideways when they hear a noise from beneath the cabin that leads them to a hidden door. What lies beyond will change their lives forever.

These aren’t your typical Call of Cthulhu scenarios where some classy, well-dressed investigator sips tea and pours over leather books in some wood paneled library. These are burning dumpsters of pure horror where a fleeing private investigator limps through some filthy back alley on a busted ankle while a howling pack of mutants try to beat them to death with the limbs of their dead friends. In other words, these are not for the faint of heart, and are intended for mature audiences only. Player discretion is advised.


Treasure for the Watcher
Paul Owen ($2.50, 14 page PDF)

A bank robbery leads the investigators into a deeper plot in this Down Darker Trails scenario. The package contains the adventure, pre-generated characters and maps.

Lost Port Royal
Andy Miller ($5.99, 66 page PDF)

Both residents and visitors of Port Royal, Jamaica, in June 1692 have noticed odd things occurring in the town. It’s about to get a lot worse. As madness and strangeness spread through Port Royal, only a small group of locals and sailors can hope to stop what is happening in the British colony. Who or what is causing the increasingly odd occurrences in the “Wickedest City on Earth” and why? If the investigators don’t find out and stop it, it could be the end of Port Royal. It might be anyway.

A Stuart-Era scenario set in the waning years of the Golden Age of Piracy in the West Indies, now known as the Caribbean. In the age of tall ships and flintlock pistols, the bustling town of Port Royal, Jamaica, is in deadly danger and only the investigators can possibly save it. Or can they?

The Plague of the Pharaohs
Allan Carey ($8.99 $4.50, 33 page PDF)

"Some things should remain buried and forgotten by history. When a team of explorers and Egyptologists take shelter in the Lost Pyramid of Renpet, they find out exactly why..."

Brought to you by award-winning Chaosium licensee, Type40, The Plague of the Pharaohs is the twelfth Call of Cthulhu adventure in the monthly Seeds of Terror range.


The Moving Star
Marina D S Rodrigues ($5.99, 43 page PDF)

The year is 2936. Almost half of Earth’s land is now a watery and icy wasteland, but thanks to the discovery of wormhole technology humans have been exploring outer space. For the last 200 years humanity has colonized a planet christened ‘Spero’, where 70% of the human race now lives.

A slow burn Call of Cthulhu scenario set in a cyberpunk future. Board The Moving Star, the largest commercial spacecraft travelling between Earth and Spero - we at The Moving Star promise you a journey you will never forget.

Cthulhu Maps - Scenario Map Pack #2 - Genius Loci
Cthulhu Architect ($7.99, 26 maps in PNG format)

All the maps needed to play Genius Loci from Doors to Darkness, available with grid or without grid and in high (140 PPI) and low (70 PPI) resolutions. Suitable for use with VTTs.

The Arkham Witch Trials of 1693
Duncan Heystek ($2.25, 21 page PDF)

The sleep town of Arkham has suffered a lot this past year. Like Salem, a bloody witch hunt has been conducted, seeing many innocents to the gallows for no logical reason. However when an old widow in town has been accused of witchcraft, strange thing begin to seep into this silent little town. Can it be mere coincidence, or is there truly witches among them?

A scenario for new players or inexperienced Keepers set in 1693 colonial Arkham.

Grieving Skies
The Death Die Club ($3.99, 32 page PDF)

The adventure takes place in Mexico in 1928 during the Cristero War. This conflict between the Mexican government and the Roman Catholic church lasted 4 years and claimed over 80,000 lives. The investigators are part of a government platoon tasked to visit towns, bolt shut churches and imprison dissidents. When the group locates the hideout of Don Jose Garzon, a prominent Cristero leader, they can´t pass up the opportunity to capture him. Unfortunately, none of them where ready for what they were about to face inside the hacienda.

Miskatonic Repository - Seeds of Terror Range

Congratulations to community creator Allan Carey of Type40! Twelve months ago he started the Seeds of Terror range on the Miskatonic Repository, with the aim creating a monthly series of accessible and exciting scenarios for Call of Cthulhu that Keepers can pick up and run in one evening.

Twelve months later, there are twelve Seeds of Terror to choose from, including the ENNIE nominated winning Hand of Glory. Each is a concise, easy-to-run Call of Cthulhu adventure designed for a single session of exciting play. Suitable for 4 to 5 players, they include maps, handouts, and five ready-to-play investigators. Everything needed to play has been presented as clearly as possible for a quick fun game. No need for hours of Keeper preparation, just pick one up, have a quick read, and dive right in!

To mark this anniversary, Type40 have put the entire range at 50% off right now.


Seeds of Terror creator Allan Carey says, "Seeds of Terror are perfect for introducing new players to Call of Cthulhu. An important goal of each adventure is to remove barriers of entry to new players. Leaning heavily on well-known tropes but at the same time subverting normal expectations, the Seeds of Terror line explores easily-referenced and familiar situations to help immerse players in the action."

Miskatonic Repository Titles August 2021

Miskatonic Repository Titles August 2021

Four-Bit Characters, Volume 1
Aaron Vanek ($5.00, 70 page PDF)

Ten pre-generated characters for use as PCs or NPCs in the Call of Cthulhu (7e) RPG. Each is based on a real historical figure, with skills, attributes, and biographies created through extensive historical research. Each character is detailed on a redesigned CoC 7e character sheet with PDF autocalculating features. Each has both a print (black and white) and digital (color) version.

The Darkened Hermitage
Brendan Lahey ($4.99, 48 page PDF)

October, 1933. As the Royal Canadian Mail steamship pulls onto the quiet lake, the seemingly interminable forest gives way, revealing the tiny hamlet pressed up against the shore, framed on all sides by the rugged mountains of backwoods Quebec. You wonder what could make someone want to live in such a dismal little town, seemingly built in defiance of God and Nature. A bitter autumn wind blows through you as you wrap your jacket tight and turn the Professor's cryptic letter over, looking at the hurried handwriting once more. What could it mean?

A horror mystery scenario set in the forested hinterlands of Quebec, Canada. The investigators have come to speak to Dr. Ezekiel Freeman, an eccentric historian and folklorist as well as a true believer in a wide range of esoteric theories. The investigators arrive to the small hamlet of Le Fidèle to find out that something has gone horribly wrong - and the next boat to Montréal doesn't come for another two weeks. The forested mountains press in like the walls of a prison cell, and the investigators are trapped in this valley with whoever - or whatever - is responsible. To survive, the investigators must work to uncover this valley's dark secrets- and soon. Who can they trust?

Number 7 Dream
James Killick ($4.96, 26 page PDF)

The whole world seems against you - watching, waiting, observing - throwing obstacles in your way, closing some doors, while opening others - like it's guiding you, herding you, like it wants you to do something, remember something - but what?

A war veteran has received a letter from his daughter saying she has gone into hiding from bad people. She begs him not to go looking for her. But what else can he do? What father wouldn't? With his war-wound finally catching up with him, he asks the only people he can really trust for help - the investigators. A modern-day scenario set in the English city of Bristol but can be changed with minimal effort to another time or place.

Creature Feature: Sepulchral Shoggoths
Chitin Proctor ($1.50, 5 page PDF)

“So I prophesied as I was commanded: and as I prophesied, there was a noise, and behold a shaking, and the bones came together, bone to his bone. And when I beheld, low, the sinews and the flesh came upon them, and the skin covered them above: but there was no breath in them.”—Ezekiel ben-Buzi

Includes 3-page Monster Write-up & Stats and Spell: Create Sepulchral Remnants.

Trutz Blanke Hans
Florian Klamt (Pay-What-You-Want, suggested price $3.53, 16 page PDF)

A modular sandbox scenario with an investigative focus. It all begins on a cold January evening on the Hallig Südfall in the German North Sea. The investigators follow the call for help by a mutual acquaintance who is looking for open-minded people to aid him in a Séance. While the time of the setting can be adapted to the group’s liking, the investigators will soon find themselves in a vivid trip back in time to the 16th of January 1362 and a race against the merciless tides.

DenMother Plays ($5.00, 22 page PDF)

Durian Hotel. One of Davao City’s beloved landmarks. However, not everything is as it seems. There have been whispers about the majestic giant facing foreclosure due to low occupancy rates. It cannot be helped, given the rising Asian economic crisis, and the hostilities between the rebels and the local government causing tourism to slow in this part of the country. It is December 1995. Christmas songs are playing throughout the local establishments. People distract themselves and celebrate the holidays, preparing for Noche Buena (Christmas Eve dinner), and other known traditions.

The scene however plays out with 4 individuals: a reporter, covering a story; a businessman, looking to cover their losses; a detective, looking to find truth; and an heiress, eyeing a political move. All of them somehow get invited to spend the night in the iconic hotel, and uncover some secrets…

The Haunting of Millebrand Manor
Scott Uhls ($4.99, 28 page PDF)

Jameson Millebrand IV is a well-known playboy in New York City and is heir to a very large fortune. However, his only major accomplishments have been attending Yale for 2 years, being an average football player, singing with a gentleman songster group, traveling across Europe and Asia, and starting an ironwork factory just in time to be part of the war effort. This last piece in his “legacy” despite being mostly about lucky timing. He has invited several friends and acquaintances to stay the night at his newly acquired “castle” mansion in the 1000 Islands area of the upstate New York, including his arranged “fiancé,” his secret ex-lover, and a semi-famous spiritualist from England. Local stories indicate that this mansion is haunted, but the evidence is shaky at best. However, this has stimulated Millebrand’s occult interests.

The investigators are among these acquaintances and are caught in the events of the dinner party and the aftermath that follows. When one of the guests ends up dead, the investigation begins to reveal that there is more here than meets the eye.

The Hammersmith Haunting
Here's a host of new titles in the Miskatonic Repository by independent Call of Cthulhu creators. Among these is Australian crime and horror writer Kat Clay's first foray into Call of Cthulhu scenario writing, and some from alumni of last month's RPG Writer Workshop, run by our friends at The Storytelling Collective!


The Hammersmith Haunting
Kat Clay ($10.00, 29 page PDF)

London 1890: ghost fever grips the suburb of Hammersmith. For three days, no person can sleep without experiencing terrible nightmares, and locals swear to have seen a ghostly medieval woman stalk the streets. Investigators find themselves trapped in Hammersmith, confronted by ghost hunters and an all-pervading fog. But is the ghost all that she appears? Or is there a more sinister reason for the Hammersmith haunting…

Cthulhu by Gaslight scenario by Australian crime and horror author Kat Clay.

"Bravo to my Melbourne friend Kat Clay, who has made the leap from writing award-winning detective fiction to publishing her debut scenario for Call of Cthulhu. And it’s a gaslight haunting. Perfection. Right up my fog-shrouded alley." — Mark Morrison (Horror on the Orient Express, Terror Australis, Reign of Terror, etc.)

Field of Screams
Al Smith ($2.99, 31 page PDF)

If you build it… THEY will come! In this baseball-themed Pulp Cthulhu scenario, investigators play members of the All Nations baseball team, a team comprised of players that have been shut out of the major leagues. Now, they’re barnstorming across the country, playing games in whatever small town will have them.

Now the owner has scheduled a game on a piece of land near a town that loves baseball. The only problem is that nobody in town wants to attend the game, because they all think that field is haunted by ghosts! The investigators are going to have to figure out what is going on with that field, and possibly, confront these evil spirits that threaten to ruin the baseball game! Little do the investigators know that these apparitions are not, in fact, ghosts, but actually something much worse. In fact, the problem may go much DEEPER than the investigators could ever expect…

Foreign Body - Call of Cthulhu
Raymond J. Hicks, Arjade Productions ($2.00, 32 page PDF)

After a long mining expedition to Antarctica, the crew of The Costaguana are on their way home when they receive an encrypted distress call from an uncharted island. What strange adventures await on their voyage home and what terrifying discoveries will be made? The only way to find out is to play.

A tense and claustrophobic homage to moder science fiction horror films, set in the 1920s Cthulhu mythos. Can you and your crew survive the Son of Kane?

The Time Shadow Over Darnesville
Paola Pedranti ($10.00, 9 page PDF)

Frank has called one of the investigators, who is an old friend of many years, saying that he is need of urgent help. He warns the investigator that he is in mortal danger and cannot trust the police. Frank asks that the investigator to come immediately and bring allies. Frank refuses to give further details, providing only an address with a house and a room number for the investigators to meet him. When the investigators arrive at the room, they find it deserted.

This stand-alone scenario takes place in the 1920s in a small, fictional American town called Darnesville.

Headless Valleys: A Call of Cthulhu Scenario for 1920s-1930s Alaska
Charlotte Lenox ($11.00, 76 page PDF)

Gold Fever strikes the last frontier of Southeast Alaska... During the 1920s, Juneau, Alaska was a booming gold town with frontiersmen, miners, businessmen, homesteaders, and miscreants. But the land was still untamed wilderness where civilization was hacked out of the dark forests and towering mountains. Danger, natural and otherwise, lurked in the spruce and hemlock, deep in the murky emerald ocean, and inside the very bones of the Earth. In nearby Silver Bow Basin, where gold mining operations are in full swing, a decapitated human body has been discovered, but the head is nowhere in sight. Who--or what--is murdering the miners, then leaving everything behind except the missing head? Is it the work of unhappy locals, wild animals, or something far worse? Something hungry...
