After extensive surveying, the area was declared safe, though reports of sinkholes in the local area did cause concern for the local populace and Vault-Tec, mainly down to the perhaps over-thought fear that the whole town would collapse down on top the Vault. The majority of the Vault was built into a mountain range and below, but some of it, namely the reactor areas and some living quarters, ended up slipping underneath the suburbs of Swallow Hills, ostensibly due to an oversight on Vault-Tec's part. The Vault was built to be made up of 278 living quarters, 50 main offices, 35 eateries and diners, 10 security stations, and 4 administration and control areas, and was designed not only to be one of the largest Vaults, but also to be an advertisement, of sorts, to the surrounding area. Infighting quickly became common among many of the older residents of the Vault and the younger, hardened arrivals from the harsh wastes, and the Ghouls inside of the irradiated Vault Reactor attempting to attack Human residents in the relatively safe area of the Vault meant that the safety of both groups was put in danger.Ĭonstruction of the Vault began in 2071, during the tense years of the Battle of Anchorage, with healthy funding from local community programs, the most notable of which came from the nearby town of Swallow Hills, due to fear of the war reaching the rest of the US. After the majority of residents left the Vault, and years of an increasingly stagnant gene-pool leading to inbreeding becoming apparent, the Vault was finally opened to wastelanders 2214, some of these wastelanders being descended from old residents who had left the Vault years prior.


Those unfortunate enough not to escape were transformed into Ghouls, killed by the high amounts of radiation and some even becoming Feral Ghouls from the intense radiation. Though the catastrophic possibility of a nuclear blast was avoided by the quick actions of a few brave souls, the radiation leaked into most of the Vault and forced the majority of the residents to evacuate to safer areas within the vault, away from the now heavily irradiated reactor room and surrounding residential blocks. The Vault survived the Great War, but was nearly destroyed by an intentional defect that the construction crew and Vault-Tec had implemented as a part of Project Safehouse's unethical Societal Preservation Program when it's nuclear core nearly detonated. Vault 45 is a large, semi-subterranean construction by Vault-Tec as a part of Project Safehouse in the California wastes built around 2073, both near and beneath the nearby town of Swallow Hills, before being occupied on the eve of the Great War.


At least we've got fresh water down here. “ This Vault's gone downhill since the Great War, but it's not like we can all complain.
