Unprecedented in scope in the new world unexpected blow of a terrible pandemic, created by human stupidity, put the world on the brink of survival. In a panic, unprepared states rushed to the other extreme, like the actions of people in the Dark Ages. As then, the city gates were closed during black smallpox, bubonic plague, or cholera, and today the countries of the race began to close the borders of the states. Those who can survive inside the enclosed space hope to acquire immunity against the next scourge, and a grateful population will be able to evolve further into the foggy future.
