I finally finished the Spires - they're in Recruit30 in the back if you want to check them out - they're pretty hard to capture appropriately in just pictures. The outer spires are all linked near their bottoms with a large circular walkway, and they're all linked to the center spires by walkways higher up. Each spire has various rooms, artwork, etc, and use a combination of stairs and water-elevators to move upward.
