When all was done great cities were laid waste and disease moved across the land and seas to visit all people. A billion individuals perished in the cosmic catastrophe. A billion more dropped dead from the diseases that could no longer be controlled. When normality finally returned those who remained alive united to rebuild the planet. People of absolute opposing views on Politics, Religion and life in general, let their hate go from them and so began civilisation anew. However, each of the sides still had their own future plans and desires. Soon thereafter everything was rebuilt and they resumed in their previous and hateful ways. The people, called Communists, still had cravings to rule the entire world. Those, called peaceful and democratic, were not far from similar aspirations. In utter stupidity, arms were again manufactured for defence. Trusting no one, the people called 'Americans' resumed in their secret building of great subterranean cities across the face of the North American Continent. These were the cities that were conceived and under construction since the great destruction of two Japanese cities during the period called World War II. Having been the wealthiest of the Earth's nations, the Americans continued with their early nuclear war survival plans, designated as "Proposition Blue". It was this proposal that expedited the construction and populating of those cities named the Omega Sub-Ground Installations: (O.S.G.I's). Constructed near more populous areas and connected by underground pneumatic travel tubes, each city was designed to host some one thousand individuals made up of the chosen elite. These were the scientists, artists and other members from the intellectual community. The 1950's through the 1980's saw the building and populating of seven O.S.G.I's at the following locations across North America: OMEGA 1 - SOUTH: Near Eldorado, Texas OMEGA 2 - NORTH: Near Burke, South Dakota OMEGA 3 - WEST: Near Pioche, Nevada OMEGA 4 - EAST: Near Toronto, (Canada) OMEGA 5 - CENTRAL: Near Manhattan, Kansas OMEGA 6 - ATLANTIC: Near Atlanta, Georgia OMEGA 7 - PACIFIC: Near Vancouver, (Canada) Greatly endangered in the asteroid disaster of the late Twentieth Century, most the cities still survived. Only two cities were utterly destroyed: OMEGA - 2 and 5. These cities were amongst America's greatest achievements, next to their endeavours in space. All the cities were under strict military control, watching the intellectuals and providing them with necessities, to keep them content.
