A 23-page supplement Includes the floor plans for a four-story fortified tower and a four-story fortified tower house. Details of how to calculate the cost of building fortifications or fine homes from stone. Includes both labeled floorplans for the game-master and unlabeled battle map floorplans for the players to use. An adventure could be created by having the player characters guard the master mason and his builders while a fortification or building was built for someone else.
