OC's are Vault Dwellers from a very large and prepared vault, that survived the nuclear winter and apocalypse. This vault specifically being NORAD under Cheyenne Mountain. Built long before Vault-tech was established, it received periodic upgrades to its systems the final being to the power systems which were contracted out to Vault-tech.
The whole of Vault being filled with the military personnel and their families was skyscrapers deep. A large enough gene pool where they did not suffer the fate of other vaults where generations later suffered from infertility. After a few hundred years, the nuclear power plant slowly began to fail, and they were unable to manufacture any new parts, due to a lack of material.
Thus a competition was held in among the younger crowd to both gather materials in the wasteland as well as locate the other Vaults along the Front-Range and see if they may have spare parts willing to trade or if they are abandoned, pilfer the parts.
