The Origin of Galactic Civilization

Humanity finally reached for the stars! On July 1, 2060, the human federation successfully developed its first light-speed engine. Just as everyone thought humanity would find a new home, tragedy struck. Nuclear war broke out. Perhaps it was a misunderstanding, perhaps it had been planned all along. In a very short time, Earth was nearly destroyed. The federation fell! January 1, 2076! Only one civilization, destined to endure forever, remained on Earth. The Human Empire, a survivor of the First Nuclear Peace Era. When war broke out, everyone in the country stood united, from the highest ranks to the lowest, making it the last victor in the struggle for survival. October 1, 2080. The Human Empire was officially established, and its civilization completed its upgrade. The galaxy is waiting for us. It's time to say goodbye to Earth. A thousand colossal star-beasts hovered above Earth as countless people shed tears, for their homeworld had fallen. The entire planet was shrouded in nuclear radiation. Countless plants and animals had died, the land was contaminated, and the water was polluted. Humanity had no choice but to face an unknown fate. Everything for humanity, everything for the Empire.
