2078
"The Super Mutants that infest the urban ruin of Washington D.C. originated in Vault 87. Those unlucky enough to have reserved space in Vault 87 soon found themselves forcefully taken to a secure part of the Vault, where they were locked in airtight chambers and exposed to a concentrated form of the F.E.V. The Overseer and his security force had no real idea what to expect; they were simply following the "plan." When the exposed Vault dwellers started transforming into Super Mutants, nearly the entire Vault population had been exposed. Those who hadn't yet metamorphosed knew what was coming, and, well...it didn't end well for humanity. ''The dwellers of Vault 87 were turned into Super Mutants in 2078, and have been a presence in the Capital Wasteland ever since. Most of those original Super Mutants have long since been killed. But whether it's because of the nature of the F.E.V. they were exposed to, or a simple underlying human instinct, the Super Mutants of the Capital Wasteland are obsessed with the preservation of their own species. Super Mutants are asexual and incapable of procreation, so their only way of reproducing is to kidnap other humans, drag them back to the Vault 87 chambers, and infect them with F.E.V. And so they have done, for nearly 200 years.Super Mutant society is loosely hierarchical, with the weaker (most recently transformed) Super Mutants generally giving way to the stronger. The Super Mutant hierarchy, as defined by the Capital Wasteland contingent of the Brotherhood of Steel, is as follows: Grunt, Brute, Master, and Behemoth. Generally speaking, the Super Mutants of the Capital Wasteland get bigger, stronger, and dumber as they age. The Behemoths are so strong and savage that they’re the only thing feared by the other Super Mutants."'' (Fallout 3 Official Game Guide faction profiles)
 * The dwellers of Vault 87 are locked in airtight chambers and exposed to the FEV by the Vault's overseer and his security, who are simply, though callously, following the "plan" laid out by Vault-Tec.

''Vault 101 was actually part of an unscrupulous social experiment. All of the other Vaults were intended to be opened at one point or another when the "all clear" signal was sent from Vault-Tec or the appropriate regulatory agency, and this indeed, did transpire, with almost universally horrific results. But Vault 101's secret plans were different: The doors were never scheduled to open. Ever. In fact, the Vault was supplied with just the type of equipment it would need to keep functioning indefinitely-like spare parts for the water processor. But this was just the beginning:'' ''The true experiment was even more devious and cunning. Although Vault 101 was about testing the human condition when a Vault never opened, this was only the first part of the plan. The "actual" experiment went far beyond that, and a select few knew the true nature; that this was to test the role of the Overseer. While the Overseer was able to interact (and even visit) the outside world via radio transmissions, and a secret tunnel from his sealed office, the rest of the inhabitants faced a much more dismal future: As far as they knew, Vault 101 was never sent an "all clear" signal, and faked radio transmissions described a nuclear-ravaged world gone mad, with absolutely no hope of existence outside of a Vault. The radio transmissions were actually recorded before the bombs even fell, and in many cases described a world even more horrible than the reality of the nuclear wasteland. The Vault 101 Overseer, like his counterparts in the other Vaults, was actually a planted Vault-Tec operative whose job it was to control the experiment from the inside.'' ''Aside from keeping up this ruse, the Overseer's other important role was to reinforce to the dwellers of Vault 101 that the outside world would never be habitable again, and that their only salvation was in the Vault. The Overseer prevented anyone from leaving the Vault, and made sure the Vault dwellers received their regular "transmission" from the outside world. People entered Vault 101 in 2077, just before the bombs fell.'' ''The Overseer died of natural causes 50 years later (in 2127), at the age of 84, after grooming a subordinate to continue the clandestine plan. The new Overseer led his people according to the same isolationist doctrine preached by his predecessor, but also attempted to garner as many senior Vault Dwellers to become complicit in this plan as possible. By 2277, the descendants of the Overseer had an entire generation of Vault Dwellers who were playing along with this plan, keeping the secrets from their children.'' ''The Overseer and his cronies continued to receive periodic information from the outside world, while those not in the know were told that things had gotten so bad that whoever was sending transmissions was no longer able to do so; reinforcing the thought that leaving the Vault was sheer suicide. The final piece of this grand experiment only truly began when the Vault Dwellers living in blissful ignorance finally realized the world outside could be accessed, and there was a possibility of life above ground. The experiment only really commenced when the Vault 101 door first opened, and a young dweller fled into the light."'' (Fallout 3 Official Game Guide faction profiles)

''The New California Republic was born from the remnants of the survivors of Vault 15 and the small walled community they founded, Shady Sands. Under the leadership of Aradesh, and with the assistance of the Vault Dweller (who saved Tandi, Aradesh's daughter and a future president of the NCR), the community prospered. Trade routes with other settlements allowed cultural exchange, and a movement to form a national entity gradually took root and won popular acceptance. In 2186, the town of Shady Sands changed its name to "New California Republic" and formed a trial council government to draft a constitution. Four more settlements joined the council, and in 2189 the NCR was voted into existence as a sprawling federation of five states: Shady Sands, Los Angeles, Maxson, Hub, and Dayglow.'' ''By post-apocalyptic standards, the NCR is a paragon of economic success and good ethical character: political enfranchisement, rule of law, a reasonable degree of physical security, and a standard of living better than mere subsistence are daily realities for it's 700,000+ citizens. Currently, the NCR in a state of transition, with rapid economic growth and a sea change in political leadership endangering its grand humanitarian ideals. Nowhere is this more evident than in the Mojave, where the occupation of Hoover Dam has improved access to electricity and water, but at the cost of straining its budget and embroiling its armed forces in a morally corrosive imperialist project.'' ''The NCR government's aim is to annex New Vegas as the republic's sixth state. While it already controls Hoover Dam, its treaty with Mr. House and the three families compels it to allot one-fifth of the dam's electrical and water production to local use free of charge. Adding injury to insult, the NCR is locked into protecting New Vegas from invasion by Caesar's legion even as it receives not one cap in tax revenue from the Strip's highly lucrative resort operations. NCR citizens in the Mojave have largely come here for economic reasons, whether as paid citizen soldiers or as prospectors and fortune-seekers."''

Finding themselves hundreds of miles from their Vault, the members of Vault 13 choose to join the villagers in establishing a new community, and their technical expertise, combined with the villagers' survival skills, allows the new settlement to grow and prosper. Two generations of the same bloodline are reunited, and their savior, the Chosen One, becomes Elder, presiding over the village in the years to come.
 * The Arroyo elder lives for many years after the destruction of the Enclave. She seems pleased that the ancient separation between Vault 13 and the Vault Dweller has been reconciled, and many are the times she tells the Chosen One she wished the Vault Dweller were alive to have seen the reconciliation take place. Certain that the safety of the new village had been secured and the new community was flourishing, the Elder passes away a few months later in her sleep. Many of the older Arroyo residents believe that she now lives in the Vault of the sky, telling the Vault Dweller of the Chosen One's brave deeds.

The seeds are said to remarkably tough, and several of them have taken root even in the most barren stretches of the wasteland.
 * Several years after buying the excavator chip from the Chosen One, Marge LeBarge is able to purchase and control both the Morningstar and the newly opened Kokoweef mines. Marge is an easy choice for Mayor, and using her new political power, she makes Redding join the growing New California Republic in return for a seat in the NCR's Hall of Congress.
 * With the destruction of the conspiracy to destroy the mutants, Broken Hills begins to thrive. Then the uranium ran out. The city, having lost its sole reason for existing, slowly disperses. The residents carry their riches with them, leaving the place a wind-swept, desolate ghost town. A few hold-outs remain, attempting to eke out a pathetic existence, but eventually, they too, disappear.

''The NCR's economy is based on two resources: its great Brahmin herds, and swaths of land that have been restored to arable condition. These provide the nation with meat, leather, and starchy vegetables. During President Tandi's presidency, regulations limited the number of cattle head and the acreage of fields that could be owned by a single person. Despite constant pressure from the Stockmen's Association and Republican Farmer's Committee, such regulations loosened only a little so long as Tandi was in office. Following her death, however, they eroded until President Kimball overturned them completely.'' ''As a result, the past 12 years have seen the rise of the Brahmin Barons and Agri-Barons: captains of industry who are, by post-apocalyptic standards, spectacularly wealthy. This has given birth to a number of cottage industries, from the rebirth of luxury goods production to "journalism" that reports on the latest purchases, commissions, and "life lessons" of the newly rich and famous.'' ''The past 12 years has also seen a change in attitudes towards collective welfare. Citizens of the NCR rarely face significant dangers on a daily basis, and survival is an assumption rather than an aspiration. Citizens are far more reluctant to share food and other resources, and the person who provides services free of charge, whether it's something as quotidian as sewing or as rarefied as surgical expertise, are now the exception rather than the rule.'' ''An added economic strain is the scarcity of salvageable goods. Sixty-five years of scavenging has done a good job of picking clean the wastes of what was once Southern California. Rare are those individuals who can make a living by scavenging and hunting what they need.'' ''A consequence of these economic and cultural transformations has been the rebirth of wage labor. Whereas one's labor was until recently seen as benefitting [sic] and belonging to a collective (whether a family or small town), it has now become a commodity. To earn their keep, many citizens must seek an employer and trade the sweat of their brow for Caps.'' ''Citizens of the NCR hold a variety of opinions about these developments. Many boast of their nation's economic strength; others decry what they feel has been lost. Many curse the selfishness of their fellow citizens, usually while pursuing aims that will benefit only themselves or their families. Here in the Vegas wastes, however, nearly all citizens will agree on one matter: opportunity has dried up back home, and to earn a fortune, one must come East."'' (Behind the Bright Lights & Big City)
 * President Wendell Peterson begins the erosion of regulations enacted by the Tandi administration to limit the number of cattle and acreage per person. This leads to the rise of brahmin barons and agricultural barons owning most arable land in the New California Republic.

Dennis Crocker: ''"I can provide a quick history lesson, if that's what you're looking for. In 2274, President Kimball sent the NCR army into the Mojave in force, with the objective of occupying and repairing Hoover Dam. Rangers and army scouts had confirmed that the dam was basically unoccupied and could be restored to an operable condition. Upon arriving at the dam, however, they discovered that a large force of tribals and robots had occupied it. This was our introduction to the Three Families, the Securitrons, and, of course, Mr. House. Using his Securitrons as intermediaries, Mr. House called for parlay. He claimed his forces had occupied Hoover Dam in order to safeguard it for our arrival. And that he was ready to turn it over to us, so long as we could agree to terms. Those terms became the Treaty of New Vegas. The Treaty recognized Mr. House's sovereignty over the Strip and granted us rights to establish military bases at the Dam and McCarran Airport. The NCR is legally permitted to send 95% of the electricity produced by the dam to our home states. The remaining 5% goes to the Strip. The treaty actually makes it illegal for the NCR to prevent its citizens, or troops on furlough, from visiting the Strip. Once on the Strip, our citizens are subject to arrest - or punishment - by House's Securitrons, though that's a rare occurrence. Our troops enjoy a different status. It's illegal for the Securitrons to take action against them. Of course, it's also illegal for our troops to carry firearms on the Strip, so there isn't much trouble they can get into. Our military police does an adequate job of keeping the troops on furlough in line. I don't envy them that task. The embassy was established a few weeks after the Treaty was signed. Basically Mr. House handed us a dumpy little building he had no interest in renovating. I'm the third ambassador to hold this post. And the first, I think, to accept its limitations. My predecessors had ambitions of engineering the annexation of the Mojave. They thought they'd convince Mr. House to join up. I've never even spoken to the man - or whatever he is. Maybe the situation will change once we've beaten the Legion once and for all." The Courier: "Go on." Dennis Crocker: "Now we mostly just keep track of the NCR citizens and troopers around and make sure they don't get in trouble, but that's Captain Pappas' job. I keep myself busy with paperwork and reports that get sent back to the NCR. It's mostly busy work, but every once in awhile, we make progress."'' (VStreetDennisCrocker.txt)
 * Mr. House recruits the Mojave Boot-Riders, Slither Kin, and a tribe of cannibals, turning them into the Three Families. Renovations of New Vegas begin.

 * Freeside has near completely degraded into lawlessness. The Kings are formed, with support from the Followers of the Apocalypse, becoming the only form of law and order in the area. Fallout: New Vegas Official Game Guide Collector's Edition p.42: "Freeside

''Las Vegas wasn't heavily damaged during the Great War, but people didn't immediately "settle" into the remnants of the old city. The various Vault tribes that emerged years later, hunted and fought among the ruins, but it was not until the "return" of Mr. House that they ceased (most) of their hostilities. Mr House directed the tribes to use his sizable quantities of pre-war construction materials to build the crude (but effective) outer walls that separate The Strip and Freeside from the rest of New Vegas. While Mr. House valued the area around Fremont Street, he ultimately viewed it as secondary in importance to the Strip itself and he had a second, inner wall that separated the two areas. When NCR prospectors (and eventually the army) arrived in the region, people typically went straight for The Strip, leaving Freeside (as it had become known by locals) as an informal stopping point. Eventually Mr. House recognized that he could use Freeside as a filter for undesirables, and pulled his favored tribes and all Securitrons into the Strip, leaving Freeside to fend for itself.'' ''In the two years that followed, Freeside has slowly degenerated into a hostile, lawless den of ne'er-do-wells. For a while, it was completely without order, but two power groups managed to come to an understanding about how the area needed to be maintained. The Kings, formed from the dispossessed remnants of unfortunate tribes, prevent all-out chaos from erupting, but do little to deal with the day-to-day nastiness that Freesiders inflict on each other. The Followers of the Apocalypse, no longer associated with the NCR, settled in the Old Mormon Fort. They receive some protection from the Kings in exchange for help with the community's basic needs (food, water, health services, and some education). Despite the oversight from the Kings and help from the Followers, the people in Freeside live in daily peril... from each other as well as outside forces."''

In the aftermath, the land that encompassed Hopeville and Ashton becomes known as the Divide among local tribes and the NCR.
 * The First Battle of Hoover Dam takes place. Caesar's Legion forces under the command of Joshua Graham attempt to take the Hoover Dam from the NCR. Although the attack is initially successful, the NCR lures the Legion into a trap and sends them retreating. Most of Boulder City is reduced to rubble in the battle.
