Only you, the mages who live in the Grey Zone, can see both incoming disasters, simultaneous and inevitable. Only you recognize the field of stars in someone's eyes as a sign of Dualism, the worship of these twin singularities. Three hundred years of history sits on your shoulders, and most people don't even believe the threat exists. Only in the Grey Zone, between the Confederation of the Cosmic All and the Meritocratic Republic of Syble, do the four types of mages mix. The people who come to the Grey Zone are rebels, heretics, pioneers and mercenaries. Some want to build a shining city in the wastes, others just want to live another day. At the heart of the Grey Zone lies the planet Exaltation, your home. It is the only habitable planet in the system of Deviance, ruled by the Quantum Circle, a group of mages that view the Goddess as a force of chaos. Everyone is free to use whatever substances they please, and hedonism is rampant. But only here can you see a threat so powerful that it echoes back from the future, and only here can you stop it. If you fail, magic is doomed, the Goddess will die, and the cold war between the Confederation and the Meritocracy is going to turn very, very hot indeed. With the power of the River of Stars and the Cosmic Deck at your fingertips, and a little luck, may you prevail! The River features: Galaxy-spanning science fantasy! Diceless, non-random resolution for non-magickal tasks Two completely different core magick systems! Card based resolution mechanics for magick! Both magic systems use the same deck of ordinary playing cards (plus jokers) -- mages just use their hand and the Cosmic River very differently Four Charts (playbooks), two for each type of magic, which further twist the way you control the universe: Weavers, Touched, Slicers, and Talented Ordinary people empowered by a twin disaster echoing backward through time! Playable with 1 GM and 2 or more additional players Source: The Publisher Website.
