"By the abjuration of Dee and the name of Claude Dansey I hereby exercise subsection D paragraph sixteen clause twelve and bind you to service from now and forevermore.
Right, that's it. You're drafted, and may whatever deity you believe in have mercy on your soul."
- The Concrete Jungle

The Laundry Files is a series of spy thriller books written by Charles Stross and set during the Lovecraftian Singularity: a time when the stars align and the barriers of our universe begin to thin allowing all manner of unspeakable extra-dimensional horror to leak into our world. Magic is mathematics and spells can be cast by computers. Ancient powers dwell in the ocean and lurk deep in the Earth, brooding over their own plans for surviving the Singularity. Despite the magnitude of these horrors they are at least native to this universe, unlike the even greater horrors lurking outside, waiting for someone to invite them in.

Although the game features a Cthulhu-themed backdrop, the setting remains primarily a spy thriller, focusing on gadgets, secret agencies, blackmail and inter-departmental betrayal. Inefficient bureaucracy is also a major theme and characters are usually under-trained and under-funded to face the threats before them.

The Vespertine Amendments will be an ongoing LARP set in the Laundry Files setting, in which players play as the agents of Capital Laundry Services, the British secret government agency dedicated to protecting the world from extra-dimensional horrors and international espionage.

Game Structure
