Nursery is a miracle of pre-war engineering, a self-contained balanced ecological system set within a deep canyon where seeds and other genetic information, preserved from the world before The Great War, have been stored. The valley floor of the canyon is rife with the flora and fauna of times past. In the early days before the bomb, scientists around the country were pondering how to save mankind from the ravages of war. Eventually their musings gave birth to a company named Vault-Tec, and the vaults. The Environmental Protection Agency viewed the vaults as only half the solution. Their concern was not only the salvation of mankind, but nature as well. With this in mind, they proposed yet another type of vault, but on a much grander scale. This vault would be used by Mother Nature herself, where she would patiently await the re-emergence of man. When the survivors of the war came forth to reclaim the earth, the Garden of Eden would await them. Thus the Nursery was conceived.
