Teiku Plains-(低空, Low Slums) is the lowest and poorest area in Amestumi, being the easiest to go through mostly flat fields of rock and ashes. Zero populated because of a thick dense fog covers the area, making it a natural barrier to keep out outsiders. There being no need for any bases or guard station in the areas. Being the first area that has high defenses, keeping most of invaders out. Leaving time for the other areas to prepare in case of an invasion force somehow made it through the fog.
