From publisher blurb: “One Starry Night” in Arkham, celestial bodies align and cause revelations from a lost city, a stolen artifact, and predictions of impending apocalypse to come together in horrifying and deadly ways. This scenario is designed for use both with Skirmisher Publishing’s Platinum-bestselling Cthulhu Live live-action role-playing game (LARP) and Chaosium’s Call of Cthulhu tabletop roleplaying game. It is written for two to five Investigators and a medium-sized staff and designed to be played over several locations all within driving or walking distance.
