Night Reign

From the back of the book: Night Reign is a roleplaying game of stealth, guile, violence and devilry for a GM and one or more players, set in a quasi-Edwardian metropolis perched on an inhospitable peninsula beset by toxic black rain and ruled by a corrupt cabal of Noble Houses. You take the role of members of the Red Right Hand, a conspiracy loyal to the recently deposed royal family, using your talents in assassination, infiltration and dark sorcery to strike out at your oppressors. Using an innovative blackjack based rules system, Night Reign brings the tension and excitement of stealth videogames to the tabletop.
