The life of a Test Subject
Vault dwellers are the descendants of pre-war citizens who sought shelter from the atomic fire of the great war in vast underground vaults. The real Purpose of the vaults was not for them to be shelters for preserving humanity. Rather than act to save humanity, vaults were built to test their population as part of the Societal Preservation Program. Most vaults were presented with a variety of scenarios, ranging from annoying to downright lethal, to gauge how humans acted in these scenarios for their own, nefarious purposes. Some were not provided with enough food synthesizers for their population, others had only men in them, or were designed to open prematurely. The purpose of this experiment was to gather data for the Enclave's projects, the exact purpose of which is unknown.
