The existence of the entire world was a result of the Nanomachine Swarm's mercy. The most frightening part was the fact that no one knew why the Nanomachine Swarm "stopped", and when it would wake up again. The world did not escape the disaster 65 years ago. The tragedy was not over, it only slowed down. Like a delayed execution, there was still a blade hanging over the head of humankind, just waiting to fall. In such circumstances, all sorts of voices, either sane or insane emerged.
There had been attempts to attack the ruins in the North to destroy the Nanomachine Swarm, but the Swarm was invincible. Even the use of nuclear weapons would not get rid of them. Some tried to reestablish control of the Nanomachine Swarm, but they ended up becoming part of the Gray River. Some people hoped to rebuild pre-war space technology and flee the planet to preserve the population, but their ambitions had no chance of success in the troubled world.
