Nobilis roleplaying game book R. Sean Borgstrom the great white book

In Nobilis, players take on the roles of the Sovereign Powers, each the personification of one single aspect of reality: night, roads, ecstasy, chains, time, water whatever the players can conceive of.

Once human, each character has been forever changed, imbued with awesome power and terrible responsibility. Heaven and Hell, angels and devils, the Giants and the Old Gods.

In Nobilis, all are united in the Great War against the Excrucians, whose goal is to destroy all Creation but all are divided by their own plots and ancient rivalries, as well.
