Council of Blackthorn is a board game for 2 to 6 players. Each player assumes the role of a member of the Council of Blackthorn. There are several different council member characters to play. Each player must build influence with the kingdom’s political factions by playing ally and building cards. Custom dice change the game conditions for each round. As players gain influence and power, they also gain hidden treason points. The players that appear to have the most power will typically gain more treason points. The player with the most treason points at the end of the game is beheaded for treason and is removed from the game. The remaining player with the most total influence points, wins the game.
