The game includes the core rules as well as a proposed default setting called The Ancient Committee on Glass, a type of urban fantasy milieu. Characters have four Attributes (Persistence, Assets, Talents, and Health) that spell P.A.T.H. Each Attribute has a "Permanent" and a "Temp" value as they fluctuate during play. Persistence starts at 5; other values are distributed from a points pool. Play proceeds through time-constrained sessions.
