Three linked scenarios
Threshold Station, Stony Ground Salvage, and The Curator’s Collection form one escalating arc.
The Prosperitas Protocols Trilogy
Three modern Pulp Cthulhu one-shots where the Mythos becomes a line item, a supply chain, and a problem that rich people think they can manage.
Set in 2026, the trilogy follows the Prosperitas Group, a consortium of ultra-wealthy pragmatists who believe the Mythos can be analyzed, contained, and monetized. They are not a cult. They do not worship anything. They are worse in a quieter way.
The scenarios run as standalone one-shots or as a tight mini-campaign about surveillance, deep-water containment, and a ritual in New Orleans that has been waiting thirty-nine years to finish.
Corporate horror
Wealthy actors treat the Mythos as leverage, containment, and portfolio risk.
Cross-scenario continuity
Marcus Moravec, Helix files, and Prosperitas monitoring keep threads moving forward.
Pulp pacing
Each one-shot runs in 3 to 4 hours with clear hooks and decisive end states.
Some things don’t stay buried. Given enough money, enough curiosity, and enough bad judgment, they get indexed instead.
The trilogy in brief
Threshold Station follows a viral bunker video into a Mojave facility where a threshold breach is waking up. Stony Ground Salvage puts the investigators aboard a grounded research yacht in the Florida Keys where recovered obelisks have become a containment problem. The Curator’s Collection ends in New Orleans, where a private auction covers for a ritual built around the same binding architecture.
The three scenarios
The bunker in the Mojave
A missing influencer, a wrong-angle video, and a Cold War site where reality has started to warp. Chelsea Moravec is alive, but not untouched.
The grounded yacht in the Keys
A research vessel, dead crew that are not all the way gone, and three stone obelisks whose placement matters more than anyone realized.
The auction in New Orleans
A Garden District sale hides a long-running ritual attempt. Edmund Voss wants the investigators in the room when the Malediction begins.
What connects them
Prosperitas Group
A private consortium of wealthy pragmatists who try to manage the Mythos instead of worshipping it.
Marcus Moravec
Helix executive, patron, and the man quietly filing reports on the investigators after the first scenario.
Obelisk architecture
What is recovered in the Keys becomes part of the ritual logic in New Orleans.
Choice carries forward
Every ending changes the next story’s state, from containment to weaponization to surveillance.
Who this is for
- GMs who want modern horror with corporate pressure behind the curtain.
- Players who like competent investigators pushing back against systems.
- Tables that enjoy continuity across linked one-shots.
- Anyone who wants the Mythos framed as a dangerous business model.
Content note: Includes manipulation, surveillance, betrayal, body horror, and existential cosmic horror. Best for mature tables comfortable with tense, morally complicated stories.
Three scenarios. One conspiracy. No clean exits.
The Properitas Protocols Trilogy follows investigators from a warped Mojave bunker to a grounded research yacht and a New Orleans ritual, with Prosperitas always one step behind.
