In Earth’s near future, climate extremes, overpopulation, food shortages, and a global pandemic led to nations collapsing and humankind on the brink of extinction. Scientists adopted a means in which the human brain was removed and surgically encased into a robotic armature; a process known as Integration. It was meant to be a temporary solution to an unavoidable crisis.

It was a good thing for decades, allowing humans to survive. But some of the Integrated saw this new form as the future of humanity. With no desire to reverse the process, the post-humanist Integrated stratified, calling themselves the Rayonne. Global war soon erupted, and Rayonne forces now seek to hunt down any remaining humans, forcing their integration, and destroying those who don’t share their views.
