In 2535 AD, a mysterious dark purple crystal ore rushed out of the ground along with a global earthquake, causing a strong radiation pollution storm. The activity areas of human civilization were compressed into fortress cities. When the disaster struck, the level of science and technology also improved. As the continent's terrain was destroyed, more flexible humanoid robots gradually became the main force in the world.
Intention: A purple nightmare spewed out from the cracks in the earth, forcing humans to dismantle their souls into gears and codes, and perform a mechanical dance called "rebirth" on the ruins.
