The king lies near death, so the princes compete to dominate the kingdom and secure the throne by grabbing as much land as possible. Each turn a card displays three actions that players can choose from - build a wall, move a wall (expanding your kingdom), place a knight, etc. When more than one player chooses the same action, however, a bidding war takes place. All kinds of bits come in this package -- walls, castles, knights and a gorgeous game board that allows for variable setups. - BoardGameGeek
