The old city in Niihama West sector is enormous. However, as expansion continued, this area grew less and less desirable for construction. At first, it was saturated with industrial pollutants. A large section of Nihama’s old-city would become a Refugee Releif Sector. The Refugees refused to move into the heavy polluted area and it was abandoned. Even though the industrial pollutants of the old city had long since been removed with MicroMachines, no one has attempted to rebuilt and repopulate this area. The area was still next to a Refugee sector and looked ugly with old, tattered buildings.
