The once desolate grasslands now stand a brand-new city, surrounded by walls of varying shades of beige, and the former mountain hollow camp has now become the western inner city.
Compared to the outer city where ordinary people reside, the mountain hollow inner city is inhabited by the core members of the organization, where precious food supplies, armaments, and other important materials are stored in the caves.
In the lower level of the caves, warm electric lights hung on the walls light up the passage, connecting to many rooms, mostly storage rooms. Due to the lack of sunlight, few people live here permanently, except for the Silkworm Moth Species.
At night, several little fellows flap their wings with excitement as they traverse the corridor to a larger room by the passageway exit. The space here is ample, with lights hanging from the ceiling illuminating around a dozen tables below.
