What happenes when science gets ahead of it's self.
Over the years there have been many mysterious disappearances. These disappearances were investigated for a couple of years and then like all the rest forgotten. Many rumors still went around that the government was behind this for some time afterwards and they weren't far from the truth. There was a team of scientists that were spread across the country in secret underground facilities where they took the kidnapped people and preformed many different experiments on them. The scientists were most interested in the combination of human DNA and animal DNA. Around the year 2036 there were sudden simultaneous explosions at every underground facility that had a shock wave of about 150 miles. In that shock wave there was some kind of radiation, for lack of a better word, that affected all those in the 150-mile area. The radiation caused the people to gain random animal like qualities. Hundreds died in the panic that followed. Of the about 30,000 people that were left unaffected about 20,000 of them became extremely frightened they built 3 domes around 3 unaffected cites and enclosed themselves in those domes and away from the madness outside. Most of the other cites became ruins as the mutants rampaged; there was no more electricity, no more running water, and no more electronics, no more anything. About 1,000 years later, a lot of small towns popped up with many different creatures inhabiting them and not one of them knew about what happened in the past or about how life was, it was all just a fairy tale now. The lights that used to emit from the domed cities are now now completely gone and no one from them were ever seen again. Those cities are now called the forbidden walls. And everything has now started anew.
