All three *main* nations (there's smaller ones that not really important) come together on the main country to have the biggest war ever in the history of mankind. But a large bilnding blue glow hits every man, warrior, and mechine. All kneel to this being as it speaks like thunder of gods. "Come and fourth and kneel to your emperor and I shall bring a new light to your world." So they obey to this god like being.
