Through the first century of the third millennium in an effort to develop immunity to the increasingly obscure and genetically created biological weapons, scientists began work on the Immunity Chip. The goal was to take man to a new evolutionary level where he could withstand any and all diseases. Using mass cell breeding, scientists tested billions of mutations until in 2125, they announced the discovery of a radically improved white blood cell. Dubbed the "White Knight," the cell's DNA sequence could withstand all disease. For the first time in the history of mankind, disease was eradicated.
