Cnon is the wealthy portion of Ocen, and 1/2 of the towers retain all of the historical documents of the world. The other three towers of Cnon retain housing units, each one containing three rooms; a living room, a dining room, and a bedroom. Rooms are not labeled, but each one has a seperate elevator to the room. Upon reaching the top, the elevators merge into one pipe. The mechanism behind this is a Cnon secret.
