Every player receives a roleplay card that says that he or she is a loyal knight of King Arthur or an evil person helping Mordred. Only some of the players know the other's personality and there is no option to reveal that. There are missions to accomplish for the kinghts and to ruin for the evils. The players are in teams, but most of them doesn't know how plays in which team. We have to figure out whom we can trust and who is going to try to kill us!
