In this GM-less game, four players inhabit the roles of four doomed musicians trying to welch on a deal they made with the devil. This game presents itself as a one-act play; wherein players are expected to “don the roles of playwright, director, performer, and audience member alike”, and as result offers a gameplay experience like nothing else in the TTRPG hobby.
