The western half of the circular tower has a slightly staggered floor, with tiers of tufted velvet benches that slope down toward the arenas. Dark purple curtains made from flowing satin surround the walls, drawing attention to the large glass windows that face the arena. A large portrait hangs on the tower's dividing wall, showcasing a scene of fierce battle.
