apparently at some point later on, some of the younger TUS characters get involved with maintanence of a series of really old, really large towers of unknown origin. My understanding is that TOG potentially takes place within these really old towers, in an artificial shinsoo filled environment. Personally, I think the contests in TOG result in somebody getting to the final floor where they gain the ability to awaken to an exis, and Zahard has implemented a system of government to prevent people aside from himself from getting there first.
