Natekeju is a planet with highly advanced technology. It is home to seven or eight billion natives and hundreds of countries, large and small. Every country has numerous powerful, influential families.
The countries maintain peace on the surface, while the families vie for power behind the scenes.
Not only does technologically advanced Natekeju possess weapons and machines capable of laying waste to the world, it has also begun exploring outer space. They have left their mark on many neighboring planets and have started researching interstellar migration.
But they seem to have reached a bottleneck. Although interstellar migration is theoretically possible, putting it into practice has proved enormously difficult.
In Taiyuan 2133, the Natekeju calendar, a mutated virus suddenly swept across the entire planet, dealing Natekeju a devastating blow.
More than five billion people around the world were infected. As the virus continued to mutate, those infected underwent bizarre changes: their eyes turned pitch-black, they lost all emotion, their bodies rotted, and they became bloodthirsty.
In Taiyuan 2134, after just one year, the virus had spread at an astonishing pace. Within only six months of the first animal mutation being discovered, animals across the entire planet had changed. In the second half of that year, robots around the world went out of control and turned against humanity. From then on, the entire planet was engulfed in the smoke of war.
