Nestled above the stockroom inside the mountain, this "tower" isn't a tower at all since the entire fortress is built into the mountain. A series of powerful ballistae mounted on rotating platforms are arranged on sliding rails, each one ready to fire at foes outside. The side of the mountain they are pointing at has been completely carved out, making this room a bit drafty but allowing for the ballistae and also archers to fire outside. Large canvas bags filled with sand and small rocks lie in orderly piles beside racks of bows and crossbows, barrels of filled quivers and bolt boxes, ballista bolts, and ballista accessories.
