When there is a serious threat looming outside for the Star Tower Participants. Unaware of it, those students begin to stay inside the Westword city after they have done participating in it. Some even tried to go out of the West Word City, but they were soon blocked by the City Lord's Patrol Guards.
Upon strict vigilance done by City Lord Garry, from time to time they find traces of forces gathering outside. After noticing the movements, He gave instructions to further tighten the measure. He has nothing to do outside. He doesn't have jurisdiction over that. All he can do is to maintain law and order inside the city.
