Semi-Historical Coup-Pocalypse

This is a TTRPG action-adventure (loosely) based on Catherine the Great's coup of her husband Peter III. Players will face daunting threats, supernatural demands, and impending doom--if they fail to figure out how to stop it. The game takes around an hour and a half, involves no premade character sheets, and uses only a d6. Play for the history, for the dystopia, or to just have fun with your friends!
