The Laundry: Going Down to Dunwich

The Laundry RPG is a roleplaying game based on the Laundry Files novels by Charles Stross in which magic is a higher order of mathematics, and solving particular theorems results in the summoning of Lovecraftian horrors. The Laundry is a bureaucratic behemoth of an anti-horror agency based in the United Kingdom, and you are its bureaucrats...and secret agents?

In "Going Down to Dunwich," you have been sent to "The Village" to attend a training course, but things are not always as they seem.
