A spinoff from the Reaching Moon MegaCorp, Convulsion was a Chaosium-themed convention run in Leicester, UK. Originally called Convulsion of the Writhing Revenants, the name was quickly shortened to Convulsion. It was inspired by the Conjunction of the Million Spheres held in Cambridge, UK in 1990 that had Greg Stafford as Guest of Honour.
