Cthulhu Eternal: Jazz Age Scenarios

Miskatonic Mysteries Series

This series of standalone scenarios all take place in the fictional Miskatonic Valley, that surreal and haunted region of Massachusetts invented by H.P. Lovecraft as the backdrop to several of his best-known short stories and novellas. Each of these scenarios can be run any time throughout the Jazz Age period (1920s and 1930s).

Three Times the Mythos: To give the GM a range of different options, the Miskatonic Mysteries scenarios feature three different possible Mythos backstories underlying the curious events portrayed. Choose whichever of the options appeals to the preferences of your individual gaming group, or re-run the scenario multiple times with different weird forces at play each time around.

Miskatonic Mysteries #1: To Touch The Untouchable

(A scenario by Dean Engelhardt)

“To Touch The Untouchable” is a short standalone investigative scenario set in H.P. Lovecraft’s notorious college town of Arkham, any time in the 1920s or 1930s.

The Protagonists are engaged by the family of a young Arkham woman, Gertrude Pettingill, who has mysteriously gone missing. A pious and obedient girl, Gertrude is seldom seen anywhere apart from the Miskatonic University Campus (where she studies) and the Arkham First Baptist Church (where she attends Bible-reading class two nights a week as well as services on Sunday). Her sudden disappearance baffles everyone … not least the Arkham Police. But fortunately the Pettingills have some friends or associates — the Protagonists — who know their way around a mystery.

To play this scenario you only require access to the Cthulhu Eternal Jazz Age SRD (bundled with purchase)

Miskatonic Mysteries #2: Help Wanted

(A scenario by Jo Kreil)

“Help Wanted” is a short standalone investigative scenario set in Arkham, any time in the 1920s or 1930s.

A strange series of ‘help wanted’ advertisements that have been appearing in the Arkham Advertiser over a period of months. Each has a very similar, and very odd, style and asks for assistance with a different specialized skill. Each advertisement runs sporadically for weeks on end, then disappears, only to be replaced with another variant a few days later.

People who respond to the ads tend to mysteriously disappear. That’s odd, even for Arkham. Who is placing the strange ads, and for what purpose? How do these events tie in with unbelievable tales about an 18th Century self-style sorcerer from Arkham’s dark past?

Playable with the Cthulhu Eternal Jazz Age SRD (bundled with purchase)

Miskatonic Mysteries #3: Smoke Green

(A scenario by Noah Lloyd)

“Smoke Green” is a short standalone investigative scenario set in Arkham, any time in the 1920s or 1930s.

A new craze is sweeping Arkham (and every other nearby city). A new brand of cigarette with a wonderfully vivid selling point — the smoke from these smoother-than-smooth cigarettes has a lustrous green hue. But not everything is mellow. The recently-built five-story Reinhart Tobacco Factory, down by the refurbished Miskatonic docks, was recently
rocked when company founder and president Reinhart Laine was discovered
murdered in his own office. Who could have wanted to kill the wealthy tycoon? Is it tied to the bitterly-fought political tussle to see who becomes Arkham’s next Mayor?

The Protagonists are engaged to get the bottom of this most baffling of mysteries.

Miskatonic Mysteries #4: Spoiled Milk

(A scenario by Jo Kreil)

“Spoiled Milk” is a short investigative scenario of Cthulhu Mythos horror, set in the countryside surrounding H.P. Lovecraft’s fictional town of Arkham, any time in the 1920s or 1930s.

A sudden rise in the number of residents falling ill after consuming spoiled milk has put the town of Arkham on high alert. People are questioning the quality of the product coming from the three main dairies supplying locals with their daily deliveries. Some have even taken to blaming bleary-eyed milkmen. Arkham seems on the brink of a milk-related uproar!

But what nobody is talking about is the … unusual … nature of the illnesses and hospitalizations reported. The Protagonists are drawn into these unexplained events … hopefully they can find a solution to the mystery before more Arkhamites fall ill … or worse.

Miskatonic Mysteries #5: Bottoms Up!

(A scenario by Rachael B. Randolph)

“Bottoms Up” is a chunky investigative scenario set in the industrial town of Bolton which sits about 4 miles north of Arkham. Briefly famous because of the Herbert West affair, Bolton is the power house of manufacturing in the Miskatonic Valley making everything from textiles to leather goods. One set of products that were once much-loved in Arkham were the beers and ales made by Bolton Brewing. With Prohibition, this century-old business has now built a business making sodas and tonics … but faces stiff competition from out-of-state companies like Moxie and Bub-L-Pep.

Bolton Brewing, however, seems to have an ace up their sleeve … albeit a very weird one. They’ve just announced the forthcoming release of some truly wild flavors. But are soda drinkers in Arkham and elsewhere really ready for “Djingula Bean” soda … or “Xuin Flower Elixir”? And what the heck is “Moon Tree Ale” …?

Beyond The Miskatonic Series

The horrors of the Cthulhu Mythos haunt the dark corners of the entire world … not just the corner of New England where Lovecraft set his most famous “Miskatonic” cycle of stories. And while it can be fun to set games in those familiar locales, it can be just as much fun to break with tradition and play out Lovecraftian-themed mysteries and adventures which take place in parts of the world seldom (if ever) visited in the source fiction.

Beyond The Miskatonic #1: The Bitter Jungle

(A Central American scenario by William Adcock)

“The Bitter Jungle” is a medium-length investigative scenario of Cthulhu Mythos horror, set in 1922 in the Central American country of British Honduras (modern-day Belize). In the years following World War I, a new-found fad is sweeping across America and Europe — chewing gum. In turn this creates vast demand for its naturally-occurring raw ingredients, in particular the sap of the Sapodilla tree.

Paul Selkirk is one of many entrepreneurs seeking to cash in on the gum boom. Sadly, his ambitious plans have been … beset by unexpected troubles, in particular a series of mysterious acts of sabotage against his plantation. Trees have been uprooted, and fences pulverised. Damage that would only be possible with the aid of heavy machinery … the kind of machinery nobody has out in the remote jungle.

The Protagonists are deputized by local police to investigate. Can they discover who … or what … is targeting the plantation?

Lost Masterpieces Series

Gifted writers have been crafting Lovecraftian Investigative Horror scenarios for over 40 years. There are now well over 1,000 original scenarios that have been published for this unique sub-genre of horror roleplaying. But, as with every creative endeavor, there are “lost treasures” — scenarios which were written by famous writers, but which never saw publication for some reason or another.

Through extensive sleuthing, we have tracked down several of these forgotten classics … and entered into arrangement to have the original pieces converted across to the Cthulhu Eternal ruleset and … finally, decades after their creation … brought to the public!

Lost Masterpieces #1: Dark Visitations

(Two golden-age scenarios by Kevin A. Ross)

We’re thrilled to be able to present two early works by Kevin, updated to work with Cthulhu EternalBoth these scenarios pit the Protagonists against the Mi-Go, one of HPL’s most imaginative creations.

A Night on Bald Mountain

The Protagonists learn of the curious disappearance of a relative — a reclusive uncle who lived near the town of Augustin, Vermont. Travelling to the remote but verdant region, they will become enmeshed in a mystery which has its roots in dark sorcery … and visitors from beyond the human sphere.

Reclamation Project

The Protagonists encounter a very odd research project being performed in secret at the university in their hometown. Why have so many of the best scientific minds on campus been summoned to provide their expertise? And why have there been a sudden spate of break-ins and prowlers reported around campus?

Cthulhu Eternal: Victorian Era Scenarios

Victorian Ventures #1: Starlight on the Gutter

  (A scenario by Simon Lee & Dean Engelhardt)

“Starlight on the Gutter” is a substantial investigative scenario set in Victorian London. It is January, 1895, and in London’s famous West End theatre district preparations are underway for a most singular production. Oscar Wilde’s Decadent play Salomé — a work that was banned until recently — will finally be seen by an audience. But not everything is going according to plan. Persistent rumours of curious happenings have attached themselves to the majestically-staged production. And Oscar Wilde — usually the most gregarious of souls — has become sullen and withdrawn. The playwright’s close friend Bosie approaches the Protagonists to try to understand the strange pall that seems to have settled over Oscar and the forthcoming play.

To play this scenario you only require access to the Cthulhu Eternal Victorian Era SRD (bundled with purchase)

Note: an actual play recording of a full play-through of this scenario was released online in February 2022.
