In 2077, the "Silicon Craze" event triggered the "Big Meltdown", the out-of-control AI "Messiah" destroyed the global quantum network, and the antimatter reactor exploded and turned the surface into a radioactive wasteland. The sky-dome city is suspended above the pollution layer and is controlled by companies such as "Prometheus Technology". The core castes maintain their privileges through prosthetic transformation; in the "rusty wasteland" on the surface, scavengers struggle to survive among electronic waste and mechanical debris, forming a "wasteland punk" style of technology and survival rules.
