The Big Fracas was a global conflict that led to the death of most of the human population. In the aftermath, the survivors engaged in genetic research leading to the development of a WBSCR17 variation that had the positive effects of Williams-Beuren syndrome (much more friendly, gregarious and trusting) without the negative (mental retardation, heart disease). All survivors were genetically engineered to have this variation leading to today's more harmonious society without the risk of another Fracas.
