It was the entire crux of the war. My society was able to use the procedure to create humans who possessed far superior potential, both physically and mentally, to the average human who underwent a natural birth. People who received the surgery -- or were the offspring of two parents who both received it, such as myself -- are known as Coordinators, and those who didn't are called Naturals.

The procedure was first made available to the public nearly fifty years ago. Since then, Coordinators have led the way in virtually every scientific field. Unfortunately...this came at the cost of polarizing humanity.
