Stephen Bull ($5.00, 63 page PDF)

Based on the short story The Black Stone by Robert E. Howard, this 1920s scenario takes a team of investigators on a journey to Hungary, tasked with following the trail of Justin Geoffrey in order to find proof of his journey.

Sensitive Cases Division is a supplement meant to provide a gaming table with an organization that has ties to official law enforcement channels but operates in an extra-legal fashion. The intent of the supplement is to provide a ready-made organization, and a set of 10 different pre-generated character types that can be plugged into a scenario. You could always use the Sensitive Cases Division and the characters as NPCS for a rival faction or antagonistic group as well.

Midwest Mythos: Heart of the Music
A.M. Viers ($3.99, 33 page PDF)

The S.S. Madam Columbia is a grand casino boat from Chicago, and is often the envy of those that are unable to board. However, with new management and the promise of Spritiualist leaders and occultists on board, along with a cheaper ticket price, the boat is open to many who might want to enjoy a night gambling, drinking, and learning about the darker side of the world. What many do not know is the secret that lays beneath the deck and how a murder on board reveals that everything is not how it appears.

Creator A.M. Viers says, "Reviews are appreciated to continue improving the quality of such scenerios. I wish to create many more situations exploring my home, the American Midwest, and every odd thing that exists within it."

We Dream of Flying
Jim Phillips (FREE, 30 page PDF)

A disparate group of international elites have, each for their own reasons, boarded Flight 19 from Los Angeles to Tokyo on a first-class ticket. The flight promises to be a quiet affair - allowing for time to rest, relax, and perhaps even get some work done. The fight is completely full, but an unfortunate coincidence and the all-too-understandable sorrow of a lonely little girl will lead them deep into a mystery from which there may be no escape.

Intended as a Modern Day exercise in mystery, character development, and role-playing interactions between the Investigators themselves, there are no monsters to be fought and no cultists to defeat. There is only a mystery, and the question of how the Investigators will ultimately choose to resolve the terrible and fantastical situation they find themselves in.

Plus new releases in Finnish, French, Korean, and Spanish!

William Bailey's Haunted Mansion
Newly-released on the Miskatonic Repository, our platform for independent Call of Cthulhu creators at DriveThruRPG, William Bailey's Haunted Mansion is a masterclass of showing how you can deftly concoct a (fictional) Cthulhu Mythos tale out of real historical happenings, bringing in known locations, authentic artefacts and documents, and actual people who lived at the time.

First presented as a live actual play production at the Ballarat Heritage Festival in May 2023, this one-shot Call of Cthulhu adventure is set in the turbulent 1890s of the historic city of Ballarat in Victoria's Goldfields, Australia. The scenario explores some of the places, figures and legends in that folklore and the machinations of a real but today largely forgotten cult which operated in western Victoria in the late 19th century; the New Lights or Stephenites, after their ruthless and charismatic leader Stephen.

We congratulate creators David Waldron and Shannon Nichols, and the talented players and musicians who brought the story to life at the gaming table! And thanks to Ballarat Libraries who helped make it all happen at the Ballarat Heritage Festival (in Call of Cthulhu, librarians are the heroes, don't you know...)

screen-shot-2023-10-03-at-1.45.30-am.png

William Bailey's Haunted Mansion
David Waldron, Shannon Nichols ($5.99, 39 page PDF)

William Bailey was a figure both idolised for his philanthropy yet infamous for his ruthlessness in business and the depths of the skulduggery involved in his running legal battles with the Learmonth family. His 1883 mansion, which still stands on Drummond St in Ballarat is often claimed to be one of Australia's most haunted buildings in local folklore.

One-shot scenario, set in 1890s Ballarat. The Investigators, based on the historical figures Detective Thomas Montague, Dr Bella Guerin, Spiritualist James Curtis, and Skeptic Clara Baldwin, will explore the mysterious events unfolding in mining magnate William Bailey's Mansion and the dark manipulations of the historic New Light cult, led by their enigmatic leader Steven.

The four pregen investigators, all the NPCs, the backstory, an evil cult and a terrifying artifact* are based on historical characters, events and objects. Illustrated throughout with period photographs and actual floorplans.

*The Ballarat Mechanics Institute's Touching the Full Redemption of Mankind by the Death and Blood of Christ Jesus is one of the only two examples of anthropodermic bibliopegy (binding books in human skin) in Australia. This real book - which you can actually go and see in the Ballarat Mechanics Institute's collection today - features in this scenario. And for more fascinating historical stories of uncovering the forgotten secrets of Ballarat’s dark and bizarre past (and potential Call of Cthulhu nightmarefuel) do check out David Waldron's award-winning Tales from Rat City podcast.

Originally, William Bailey's Haunted Mansion took shape as a live historical roleplaying session at the Ballarat Heritage Festival in May 2023, held at the town hall. You can watch the performance here:

Zgrozy from Beyond anthology
Zgrozy started in Poland and quickly became very popular both there and in the English-speaking Call of Cthulhu community, having released over 30 supplements—scenarios, bestiaries, and more—on the Miskatonic Repository, Chaosium's platform for independent Call of Cthulhu creators at DriveThruRPG.

The Zgrozy: From Beyond anthology contains eight Call of Cthulhu scenarios from the well-received series. It includes Shepherd of Moths, Future Echoes, The Vernissage, A Greater Goal, Noctilline, Lords by Birthright, An Inner Call, and The Mist Sower. The anthology also includes two new guides: Let Cthulhu Happen!, about running non-linear Call of Cthulhu games, and Campaigns From Beyond, about combining Zgrozy scenarios into a campaign. It is available in PDF, and Standard and Premium POD.

“Zgrozy” is a slightly archaic Polish word for “Horrors” or “Terrors.” Following advice from English-speaking Call of Cthulhu fans, the team decided to keep the original title for foreign releases, since it sounds suitably unspeakable and blasphemous to non-Polish ears.

To find out more about Zgrozy, visit their Facebook page or see their other English releases.

Zgorzy banner

Zgrozy: From Beyond - scenario anthology for Call of Cthulhu
Marek Golonka, Michał Gralak, Sylwester Gdela, Piotr Kozioł, Keith Mageau ($19.99 for PDF, plus POD options, 199 pages)

This anthology contains eight scenarios – each of them can be played independently over the course of one or two sessions and is easy to insert into any campaign. By default, scenarios occur in the 1920s, but most convert easily to other eras.

Note, if you already own one or more of these titles you will receive a discount: see the product listing for details.

Here are six new community content releases in the Miskatonic Repository that – despite being set from Regency England to the Summer of Love in Los Angeles – all share a common eldritch theme: music.

These independently-created Call of Cthulhu releases show off the amazing versitility of the Call of Cthulhu system. Anywhere your imagination takes you, a mythos adventure could ensue!

Cotton-Eyed Joe
James Bunnell, Sabrina Haenze ($8.99, 44 pages)

June, 1956: A team from the Royal Jaune Records label arrives in Bon Marais, Louisiana, in search of the original lyrics to the popular folk song "Cotton-Eyed Joe." The family of local folk legend Rory Welch claims to have those lyrics and have promised to release them...for a sizeable sum, of course. But dark and terrible things lurk in the Louisiana swamps, and you may find yourselves getting more than what you bargained for in this lyrical deal.

opera456397.jpeg


A Night at the Opera - a Regency Cthulhu Scenario
Kevin Kreiner ($6.95, 42 page PDF)

A weekend long party featuring an opera never before performed in England, and you are invited. A fine way to start the social season, this event will no doubt be all they talk about in London. Granted, our host is an eccentric man; with curious tastes that some scoundrels would call depraved. His gardens; his art collection, and his library will certainly be worth exploring. Of course, there will be music; and dancing, and the latest fashions.

For use with Call of Cthulhu's Regency Cthulhu setting.

fabntasric455749.png


Fantastic Light Display
Adam Wright ($2.99, 27 page PDF)

One-shot for 2-4 players set during a 1920s music festival at Miskatonic University. Investigators will need to discover the cause of a mysterious death at the festival. Is it cosmic, human, or something else entirely?

Will they be able to save the show or are they taking their final bow?

Set in Amsterdam in the 1930s, but the scenario can easily be transported to another theatre in another time.

Jazmin Ospa, Meghan Kuschner ($4.95, 17 page PDF)

1812, Nassau, Bahamas. The Investigators are celebrating the wedding of the Governor's daughter to a Naval Officer. At the lavish party, Tricky Jack and his Troubadours entertain the guests. A trick is then played on the bride...or is it really a trick?

Independent Call of Cthulhu creator Marcus Bone poses the question, Should you buy this scenario? for his new Miskatonic Repository scenario, Stench of an Open Grave... and gives a compelling answer:

"This scenario was created with the express purpose of introducing new players to Cthulhu Dark Ages and as such presents what I hope is a simple, almost linear, mystery for them to explore. With this audience in mind, ‘Stench’ attempts to downplay the more fantastical elements that can sometimes seep into Dark Ages games and instead tries to bring to life the culture and experience of living in the Early Middle Ages. Of course, this may mean more experienced role-players (especially those well versed in the Dark Ages) might find the story a little too simplistic for their tastes, but nevertheless I would still like to think that you ‘hold in your hand’ a well thought out, fun scenario; one that can give a good night or two’s entertainment for any fan of the Cthulhu Mythos."

Stench of an Open Grave - A Cthulhu Dark Ages Scenario
Marcus Bone ($6.00, 47 page PDF)

Ideal also for Keepers looking to run a dark - yet simple - mystery set in the early Middle Ages, it gives you everything you need (including three pregenerated characters - created specifically for the scenario) to bring this world - and its horrors - to life.

But also a question must be asked: What would you trade?

Children of the Web
Zachary Pagram ($3.00, 16 page PDF)

However… these are no ordinary spiders, and you’re not the first team to go looking for them. All that remains of the previous expedition is a trail hacked through the jungle, and an abandoned seaplane. Investigators must overcome the threats of the jungle, explore a time-lost ruin, and evade the notice of the Spider God, Atlach-Nacha.

Tuorsjaure - A shadow of what once was
Oscar Sedholm ($4.99, 30 page PDF)

"Åke Rönnkvist was gone. And it wasn’t just him, but his entire house and yard had been swallowed by the earth. Even the dog pen and the garage were gone. The only thing that remained was an enormous, gaping, dark hole. At the bottom - at least a twenty-metre drop - roots, gravel, and rocks were the only things visible now. News agencies swarmed the place for a few days and seismologists proclaimed it “the freak accident of the century”.

A sinkhole in a region where this is unheard of. Even the BBC visited the small, unseemly village of Tuorsjaure, at what they described as the ‘edge of the world in the ancestral lands of the Sámi people’. The locals were not impressed. Part of the Northern Lights and Darkness Collection.

On Air

Yet soon after, Adley was dismayed to find several items delivered to the wrong address, and now the prized cabinet is missing! Worse yet, the winning bidder threatens to sue him into insolvency if he does not produce it within a handful of days.

Last threads of Sanity
Joel Kumpulainen ($2.12, 28 page PDF)

100 People to Encounter in Kingsport
Adrian Kennelly ($1.99, 12 page PDF)

This is a collection of 100 people that investigators could encounter in Kingsport. They tend to be those that are most likely to be encountered, rather than general members of the populace, and as a result include a lot of people working at different businesses in the town, though there are others as well, from students to retirees. Most are not in positions of real importance and most have no knowledge of the Mythos, though some may brush its edges.

Broken Dreams
