York City was one of the few U.S. cities that survived the destruction of a nuclear war. The democratic status of the city slowly began to change as the city's leaders began stripping away the rights of the lower-class population. The self-proclaimed nobility provided themselves with a fresh, new urban city to further separate themselves from the lower class. The new city, the Citadel, was equipped with the latest gadgetry and encompassed more usable land than ever existed in York City. Unbeknownst to the Citadel's elite it was also built directly above an underground sanctuary complex. Once again there was a place where people could live and breathe without persecution and discrimination. Once again families could raise their children without the meddlesome interference of a government that forced their decisions upon them. Once again, even in a world bound by flex-stone and man-made walls, there could be freedom - Underground.
