Assassins, Templars, Rosicrucians and Illuminates start the hunt for the grail. The pawns on the gameboard belong to nobody, each player may move each of them. Throughout the game, however, each player may try to gain control over the pawns by secretly exerting influence on them. The winner of the game is not the one who brings home the grail, but the one who controls the bearer of the grail; in other words: The one who proves to have the highest influence ...

Clockwise, the players move one of the pawns on the gameboard, or invest hidden influence points. Displeasing moves by other players may be rejected if you reveal to have a higher influence on that pawn than the player who made the move. Furthermore, displeasing pawns can be removed from the game by uncovering them. But in order to do so, you have to control the pawn which blows the other pawn's cover, and the amount of influence you can spend during the game is limited.
