The Purge Plague ravaged the planet, and within a hundred years, the devastation eradicated all animal life. Vegetable protein sources also suffered, with thousands of species dying off every year. Proteins needed to sustain life disappeared from the planet, and all species dependent on consuming those proteins disappeared.

Humans now lacked the essential proteins necessary to sustain life. Only a few million survived, where once there were nine billion people on the planet. These last few were on the brink of obsolescence. Only by sheer luck and determination did scientists save humans from extinction. However, it came at a great expense to the survivors.

Jump ahead a thousand years. Following the chaos and anarchy that ensued, the surviving human community eventually developed a culture that could stave off the extinction of the entire species. From the day one was born, men and women alike knew where their next meal came from and their eventual fate.
