Whether it was environmental degradation, war, famine, disease, a natural disaster, or something else, in the course of approximately 125 years, the human population was a shadow of its former self, with world population approximately around 100 million. Modern society, so dependent on complex systems designed to sustain the populace quickly broke down, and most nation-states became history or shadows of their former selves. Most of humanity was reduced to an almost barbaric state, roaming the lands and warring with other bands over the remnants of once-glorious civilization.
