Welcome to St. Cloud is somewhere in-between a campaign setting and a scenario and can be adapted to any system, though it is meant to be a scenario for the Wretchedverse, especially for our horror/ dark urban fantasy game Wretched Darkness.
It is surreal horror in nature since it was heavily inspired by David Lynch's cult TV show Twin Peaks (1990), but it leans on other sources, like John Carpenter's The Fog (1980), The League of Gentleman (1999), Carnivàle (2003) and 1970s slasher flicks.
There isn't specific mythology, and even the amount of supernatural and/or paranormal
phenomena can be easily modified to suit different tastes.
What's presented here is a detailed description of the titular small town of St. Cloud, WA, and its inhabitants, which provides multiple story seeds.
In the end, there's a much more developed but unstructured plot hook that encompasses a series of events set in motion after the death of a local preteen girl.
The final chapter, (Not) Wrapped in Plastic, is a plotline designed for those who want to
play St. Cloud with a distinct Twin Peak's feeling, but without instantly giving away the whole story.
If this and some of the characters' descriptions sound familiar at a glance (you're right, of course, it does!), that's only a superficial similarity, however.
Indeed the inspiration isn't masqueraded, but St. Cloud can be run even if in your
group there are players familiar with Lynch's work since the characters and the town's dirty little secrets are pretty different from the source. What remains very similar are the eerie atmosphere and the overall semblance of a soap opera gone insane.
