⬛︎ Rubicon Control Federation

A nation that has achieved unprecedented prosperity through highly developed science and technology and thorough urban management.

People enjoy safe and affluent lives, and most urban functions are managed by AI.

▲ Lumina City

A cutting-edge megacity located at the center of the Rubicon Control Federation.

Shining white skyscrapers, vast glass-walled facilities, unmanned transport flying through the air, and an AI that manages the entire city. The streets are always kept clean, and all functions such as medical care, transportation, and logistics are highly automated.

Crime rate is zero. Citizens lead safe and comfortable lives.

▼ Nova

A massive underground city sprawling deep beneath Lumina City. Sunlight never reaches here, and the morning begins with the glow of artificial lights.

Dim corridors, exposed piping, countless wires, old buildings, and modified machinery. In contrast to Lumina, public safety is poor, and some residents lack official registration.

Management by the Rubicon government is insufficient, and there is a vast divide between the surface and the underground.

⬛︎ Nova District 1

A district where the machinery industry is particularly thriving, even within Nova, gathering many factories, repair workshops, metal processing plants, and machine part shops.

Technology for recovering discarded machinery and equipment from the surface to repair, modify, and reuse them is highly developed. The sounds of machinery and metal are constant, and pipes and wiring are intricately intertwined.
