Role playing game based on easy rules and a variable mapboard created by tile placement. Players select a character to play, distribute freely 10 points of attributes (strength,dexterity and intelligence) and begin to explore an aleatory world, killing monsters and accomplishing missions to get victory points. The map tiles have paths that must be connected one with another and the players can move only thought the path. When one character moves out of the board a new tile is placed and he can find a new mission, a monster or the entry to a small secondary mapboard: lake, dwell, wood, etc. Every player has an individual mission and there is the global mission of "finding Excalibur" that is active for all players. Characters can attack one another to steal weapons, objects and mission cards. Combat is resolved by very simple rules.
