Like Ed Bourelle's Wizard's Tower set, this set features similar quadrants, with ground level entrance, stairs, stables, and storage. The higher levels include stairs, armory, murder holes, gate winch, meeting area, upper storage, food storage, dining, kitchen, barracks, sergeant's quarters, noble's quarters, and servant's quarters. There's also an entrance to the roof levels and some dungeon tiles.
Although on the surface this set might seem compatible with the Wizard's Tower, it's got limited compatibility because the wall features don't all match up. Without that other set, these maps are for humanoids only.
