History of the Brotherhood of Steel

The Brotherhood of Steel is a techno-religious faction in North America, whose main mission is to recover pre-War technology. They have a long history with roots stemming from the United States Armed Forces.
==History==
The founder of the Brotherhood of Steel was Captain Roger Maxson of the United States Army. Maxson was a member of a military team commanded by Colonel Robert Spindel, originally sent to the West-Tek research facility on January 3, 2076 by the U.S. Army to monitor the experiments being conducted there by West-Tek on behalf of the American government in the interest of national security.The Vault Dweller: "{207}{}{Base Information}": "{211}{}{West Tech Research Facility: Founded in 2002 as a private contractor for the United States government, the company initially consisted of two divisions--the Advanced Weapons Research and the Biomedical Sciences divisions.}""{241}{}{ In 2069, West Tech was the single largest contractor for the United States government; its largest contract being Powered Infantry Armor Model T-51b. }""{242}{}{In light of significant advances in 2076 by the NBC on the Pan-Immunity Virion Project, the United States Defense Department, in fear of international espionage,}""{243}{}{ moved a team onto the site to secure and oversee the project, now dubbed the FEV (Forced Evolutionary Virus) project.}"(GPWRTERM.MSG)Fallout Bible 0: "2076	January	3	 A military team under the command of Colonel Spindel is sent to the West Tek research facility to monitor the experiments in the interest of national security. Captain Roger Maxson (the grandfather of John Maxson, the High Elder of the Brotherhood of Steel in F1) is among the team personnel." On January 7, 2077, all West-Tek military research was moved to the newly-constructed Mariposa Military Base, along with Spindel's team, to enhance the research's security.FEV experiment disk, January 7, 2077 entry
On October 10, 2077, Captain Maxson and his men discovered, to their horror, that the West-Tek scientists at Mariposa were using military prisoners as involuntary test subjects in their experiments with the genetically-engineered Forced Evolutionary Virus.Captain Maxson's diary; Oct. 10 2077 After interrogating Robert Anderson, the chief scientist on the West-Tek research team, and learning about the extent of their scientific experiments on military prisoners, Maxson executed Anderson in disgust,Captain Maxson's diary; Oct. 13 2077 and the other scientists soon followed their leader to the firing squad.
Morale in the base broke down, and Colonel Spindel suffered a mental breakdown, eventually committing suicide five days later.Captain Maxson's diary; Oct. 15 2077 Captain Maxson's men turned to him for leadership in the midst of the crisis.Captain Maxson's diary; Oct. 18 2077 Maxson, now in control of the entire Mariposa base, declared himself to be in full desertion from the U.S Army via radio on October 20, 2077.Captain Maxson's diary; Oct. 20 2077 He got no response from the Army chain-of-command, as the rest of the Army was too busy fighting the Chinese threat.Captain Maxson's diary; Oct. 22 2077 Three days later, on October 23, 2077, the nuclear arsenals of both sides were launched, and the Great War ended two hours after it started, with most of the Earth reduced to a radioactive wasteland.Captain Maxson's diary; Oct. 23 2077
The Mariposa Military Base survived the nuclear exchange that devastated the United States, the soldiers within protected from the radiation and FEV flooding into the newly created wasteland by the base's highly-effective nuclear, biological and chemical weapons protection protocols. Two days later at Mariposa, on October 25, 2077, an Army scout in power armor (Platner) was sent out to get specific readings on the atmosphere. He reported no significant amounts of radiation in the area surrounding the facility.Captain Maxson's diary; Oct. 25 2077 After burying the bodies of the executed scientists in the wastes outside of Mariposa,Captain Maxson's diary; Oct. 26 2077 the soldiers sealed the military base, then headed out into the desert, taking supplies and weapon schematics from the base with them. Captain Maxson led his men and their families to the government fallout bunker at Lost Hills in California (this event was later called the Exodus).Captain Maxson's diary; Oct. 27 2077 In November 2077, after a few weeks in the wasteland, the soldiers and their families arrived at the Lost Hills bunker, suffering many casualties along the way from the terrible conditions of the Wasteland, including Maxson's wife (but not his teenage son). The Lost Hills bunker became the headquarters of the newly formed paramilitary organization that Maxson created and named the Brotherhood of Steel,Official Fallout Twitter: "November 2077, a month after the Great War, army Captain Roger Maxson arrived with survivors at the Californian bunker of Lost Hills. There he formed the Brotherhood of Steel, who used a functioning satellite to extend their reach across America… all the way to Appalachia." intending to use its resources to eventually rebuild human civilization, no matter the cost.
===Early years===
Little is known about the early years of the Brotherhood of Steel. During the Exodus a faction led by Sergeant Dennis Allen split away from the group that became the Brotherhood of Steel to investigate West Tek research facility for advanced technology to recover and were never heard from again. Despite that, under the leadership of Roger Maxson, the Brotherhood grew in strength, further developing their technology, and the orders of knights, scribes and paladins were formed. In 2135, Roger Maxson died of cancer, and his son took over as the new high elder of the Brotherhood.
In the 2150s, the Brotherhood established its control over the areas surrounding the Lost Hills bunker, becoming one of the major powers in New California. Sometime in the early 2150s, a raider group known as the Vipers began to establish a power base in the badlands to the south of the Lost Hills Bunker. Driven by a religious frenzy (and the need to provide for their much larger numbers of soldiers and disciples), they began raiding more frequently than before, eventually attracting the attention of the Brotherhood of Steel. 
In 2155, the Brotherhood sent out a few squads of scouts to track the Vipers down. This was more of a training exercise conducted by the high elder than anything else, as the Brotherhood was convinced that a small detachment of troops in power armor would be sufficient to deal with a group of raiders, no matter how large. One Brotherhood squad, led by High Elder Maxson, found the Vipers. Expecting the raiders to break and run at the sight of soldiers in power armor, Maxson did not take into account the religious zeal and ferocity of the Vipers, or their poisoned weapons. A single arrow nicked him while his helmet was off, causing him to die a few short hours later. John Maxson, the grandson of Roger, took up the role of high elder, and Rhombus became the new head of the paladins and the order of knights.
The paladins, now led by Rhombus, began a full-scale campaign against the Vipers, tracking them down and wiping out almost all of their members within the span of a month. Some of the Vipers were able to flee north and east into the Sierra Nevada mountain range.
During the campaign, the Brotherhood sent a few scouts and emissaries to the Hub to track down the Vipers' members, and from these beginnings, the Hub and the Brotherhood opened full trade relations (caravans had delivered to the Brotherhood before, but not long after the destruction of the Vipers, caravan trains ran directly from the Hub to the Brotherhood's headquarters at Lost Hills on a regular basis).
===The super mutants===
Several years later, the Brotherhood faced an enemy far greater than any band of raiders. In October of 2161, a Brotherhood of Steel patrol came across a dead super mutant in the badlands. They took the corpse back to the scribes, and Head Scribe Vree began to study it. After several long examinations, it was shown to be completely sterile.
In 2162, the Vault Dweller arrived at the Brotherhood's base at Lost Hills, wanting to join them. He was not taken seriously and sent on the usual fool's errand to the ruins of the West Tek research facility, renamed "The Glow" after a Chinese nuclear attack during the Great War made the facility a radioactive death trap. He surprised everyone by not only returning alive but also succeeding in his mission (he was tasked with finding a holodisk with the record of an expedition of several Brotherhood paladins to the Glow). As a result, he was the first outsider in a very long time to be accepted as a member of the Brotherhood of Steel, even though some prominent members of the Brotherhood resisted his joining the organization.
It was from the Vault Dweller that the Brotherhood learned about the Master's mutant army and his plans to turn all human survivors into super mutants. With the support of High Elder John Maxson, the Vault Dweller managed to convince the council of elders to send a squad of paladins to the Mariposa Base (which had been, coincidentally, where the Brotherhood originated, although not even Maxson was aware of that), where the Master's FEV vats were located. With the help of the Brotherhood, the Vault Dweller eventually managed to defeat the Master and was never seen again in the Lost Hills bunker. The Brotherhood at this time appeared to be the most technologically advanced faction encountered in New California. Although the super mutant army and the Gun Runners had access to more advanced weaponry, the Brotherhood had a monopoly on power armor, certain medical technologies like cybernetics and advanced supercomputers.
===Apex of Power, Stagnation, and Recovery===
===War with the NCR===
The Mojave chapter of the Brotherhood of Steel was still fighting the NCR as late as 2274. After establishing a base at HELIOS One, the Mojave Brotherhood soon found themselves at odds with the NCR and its growing power in the region. Eventually, the NCR sought to control HELIOS One, and the Brotherhood, under the orders of their elder, Elijah, refused to leave. This led to a confrontation between the two, and in the typical chain of events, the Brotherhood's superior technology was no match for the NCR's superior numbers. Defeated, over half of the chapter killed, the Brotherhood retreated to the Hidden Valley bunker, where Nolan McNamara (in light of Elijah's disappearance following the battle) was named elder and placed the bunker under lockdown. Since then, the Brotherhood's presence in the Mojave Wasteland has been confined to only a few scouting missions.
Elijah set up a plan and fortress in the Sierra Madre Resort. His goal was to break into the casino vault by capturing anyone foolish enough to set foot into his traps, collar them and force them to help him break inside. His objective was to use the casino to send the Cloud soaring over Nevada and California, suffocating everybody, so that soon the Brotherhood could truly occupy the areas when the Cloud cleared and everybody had died. However, his plans were vanquished by the Courier.
==Brotherhood of Steel in the East==
===The Appalachian Brotherhood===
===The First Expeditionary Force===
===The Capitol Expedition===
In the year 2254, sometime after the destruction of the west coast Enclave, the Brotherhood's ruling council, based in the Lost Hills bunker in Southern California, decided to send a contingent of soldiers all the way to the East Coast, with three important objectives. First, to scour the ruins of Washington, D.C., once the nation's capital, to recover any and all advanced technology. Second, to investigate the reports of super mutant activity in the area, and third, to re-establish contact with the Midwestern Brotherhood of Steel and return them under Lost Hills command.
And so a small but hardened contingent of Brotherhood of Steel soldiers, led by an idealistic paladin named Owyn Lyons (and accompanied by his friend and technological adviser Reginald Rothchild, as well as his three-year-old daughter Sarah) set out from the Lost Hills Bunker in California, and began the long trek east to what was once Washington, D.C.
===Scourge===
On their way to the Capital Wasteland, the Brotherhood's forces came across the ruins of Pittsburgh, Pennsylvania. A truly chaotic city, it was full of gangs, raiders, slavers, and many other kinds of horrors all freely wandered, terrorizing the few innocent survivors.Lone Wanderer: "What was the Scourge?"Kodiak: "It was a Brotherhood operation. They marched in and swept the place clean. Most of the people there were half-mutated, cancerous, vile things. And these people... r--- gangs, torture squads... it was pure chaos there. The Scourge is the best thing that could have happened to it. This was way back, before the Citadel was fortified. Part of the early recon after the Brotherhood first arrived in this area. One night, a squad of Brothers led by Paladin Lyons swept into the city from over Mount Wash, tearing apart anyone who stood against them. They were completely outnumbered. And still they razed that place to the ground."(Kodiak's dialogue) In a single night, the Brotherhood swept through the city from their staging area at Mount Wash, and eliminated any resident who put up a fight.Fallout 3 Official Game Guide Game of the Year Edition pp. 43-44:"In 2042, Star Paladin Lyons of the Brotherhood of Steel led the Scourge, a large-scale military action that wiped out nearly the entire population of The Pitt. In a single night, the Brotherhood swept through the city, eliminating any resident who put up a fight. Although the intent of the Scourge remains unclear, several unmutated children were taken from The Pitt by the Brotherhood and placed into initiate training. The motivations for the Scourge are unclear to this day, but many in the Brotherhood note that it was a marked change in the way the Brotherhood operates. Additionally, it is known that something was recovered from The Pitt during the Scourge, although to date it would seem that only Elder Lyons knows what it was.It is said that a Brotherhood of Steel Paladin from the Scourge stayed on in The Pitt, seeking to bring law and order to the unwashed masses and creating an underclass of Pitt Slaves in the process, guarded by Pitt Raiders under his personal command. However, in the decades following the events of the Scourge, nobody has heard anything from The Pitt. Travelers who have gone to investigate have not returned, and no survivors have emerged."(Fallout 3 Official Game Guide faction profiles) Lyons' contingent left the city with approximately 20 children in tow, who would later be initiated into the Brotherhood.The Lone Wanderer: "How did you escape?"Kodiak:"As they swept through, the Brotherhood policed up every non-mutie child they could find. Turns out, there weren't that many. Me and maybe twenty others. The younger we were, the less of a chance that we were mutated. It was ugly work, no doubt, but it had to be done. I'll never forget the sight of the Brotherhood of Steel breaching the breast of the mountain at dawn."(Kodiak's dialogue) During the Scourge, Lyons' forces suffered only one casualty: Paladin Ishmael Ashur, who was buried in rubble during the fighting and presumed dead.
===Arrival===
When the group finally arrived in the Capital Wasteland, it did not take long before they made some remarkable discoveries.
The Pentagon, as they had feared, was largely destroyed. But its sub-levels remained intact and contained enough pre-War technology and weaponry to keep Lyons’ forces going indefinitely (once the defense robots were destroyed). But there was something else, as well: Liberty Prime, a technological marvel that, if restored, could help the Brotherhood of Steel rebuild strength and reputation that had been declining steadily for years.
The discovery was significant enough to earn Paladin Lyons a battlefield promotion to elder, and a new directive from his superiors in Southern California: to establish a new, permanent Brotherhood base in the Capital Wasteland, and continue the search for any other advanced technology hidden in the former capital city's ruins.
Lyons accepted his new post gladly and founded the Citadel, built into and beneath the ruins of the Pentagon. It was a fortress the Brotherhood of Steel desperately needed, and one they rushed to fortify, thanks to their other great discovery in the Capital Wasteland: Super mutants also existed on the East Coast.
===The super mutant threat===
It did not take long for Elder Lyons and the Brotherhood of Steel to find the super mutants, mostly because they didn't have to look: the Super mutants found them. In the Capital Wasteland, particularly in the urban ruins of downtown D.C., the super mutants were simply too numerous to be avoided.
That is why, for the people of the Capital Wasteland, the arrival of the Brotherhood of Steel became the answer to their prayers. Scattered, hungry and largely disorganized, they had lived with the constant threat of death or capture by the super mutants for as long as they could remember. Elder Lyons and his knights and paladins changed all that. For the first time, the super mutant tide was stemmed and forced back into the ruins of Washington. The D.C. ruins remained under super mutant control and uninhabitable, but the number of incursions against the outlying wasteland settlements dropped significantly. Life was still harsh and unfair, but at least now the people of the Capital Wasteland had a fighting chance, and they had Elder Lyons and the Brotherhood to thank for that.
===New objectives===
Fighting the super mutants, or simply keeping them at bay, may have been enough for the region's innocent wastelanders, but for the Brotherhood, too many questions remained: how had these local super mutants been created? Were they related to the super mutants of New California? Why were they capturing the people of the Capital Wasteland? Where were they taking them? Finding these answers would ultimately, become Owyn Lyons' obsession.
The years passed, but not in a way anyone had foreseen. Indeed, the Brotherhood of Steel's importance to the people of the Capital Wasteland was not something that Lyons had ever expected. Nor was it something his Brotherhood superiors back in California cared at all about. Their newest elder had a clearly defined mission: to acquire advanced technologies in and around the ruins of Washington, D.C. Finding the source of the super mutant threat and destroying it was important too, of course. But it was assumed that the Brotherhood could easily eliminate the super mutants and their source fairly quickly. For the Brotherhood leadership, Elder Lyons’ prime objective was, first and foremost, the acquisition and preservation of pre-Great War technology. The super mutants were his second priority. This was the subject of every communication from the Brotherhood of Steel leadership in California.
But Elder Owyn Lyons had another priority, one he considered more important than his original directive or any orders received since: the protection of the innocent people of the Capital Wasteland. And so, Lyons sent word to his superiors that he would continue his search for technology when he was damned good and ready, and would not sacrifice the people who had come to rely on the bravery and strength of the Brotherhood of Steel.
The Californian corridors of the Brotherhood's Lost Hills headquarters erupted in rumor and speculation. Had Owyn Lyons “gone native,” putting the needs of the people of D.C. above those of the Brotherhood itself? Or had a Brotherhood elder finally exhibited the selfless behavior that should serve as a model for the entire order? Caught in the middle, the ruling elders made the only decision they could; they would still recognize Elder Lyons as a leader of the Brotherhood of Steel, and the Citadel as their D.C. headquarters. But all material and personnel support from the West Coast was completely cut off. If Lyons wanted to pursue his own agenda on the East Coast, he would do it alone.
So that is what Lyons did. The East Coast division of the Brotherhood of Steel, headquartered in the Citadel, became its own entity like the Midwestern Brotherhood of Steel: keep its laws and customs but no more affiliated with the original Brotherhood of Steel on the West Coast and completely independent.
===Outcasts===
Most of Elder Lyons' soldiers supported his dedication to the welfare of the people of the Capital Wasteland and were proud of their leader's commitment to honor and heroism. But there were those who voiced their opposition; loudly and aggressively. They believed that by abandoning the Brotherhood of Steel's primary mission of acquiring lost technologies, Elder Lyons had abandoned the very values that defined the order itself.
One night, the dissenters (under the leadership of Paladin Casdin) departed from the Citadel, absconding with weapons, power armor and other pieces of advanced technology and equipment. This was, without question, Owyn Lyons' darkest hour. He had become a man of compassion and understanding, and could not help but sympathize with those who had left: he had abandoned the Brotherhood's primary mission. He recognized that and took full responsibility. Some of the knights and paladins who left had been his brothers in arms for years. Together, they had shared victory and loss, pain and elation. But to those soldiers loyal to Elder Lyons, this dereliction of duty and theft of technology was an act of cowardice and treason. Lyons was left with little choice: he branded the dissenters Outcasts, traitors to the Brotherhood of Steel; it was a name they would ultimately wear like a badge of honor, proud of the distance it put between themselves and Lyons' "soldier sycophants."
==After arrival==
In 2277, Elder Lyons' daughter Sarah is one of the Brotherhood's fiercest warriors and commands her own elite squad, Lyons' Pride. Without reinforcements from the West Coast, Lyons has been forced to recruit locally from the wastelander settlements, and the results have been less than stellar: most new recruits are overeager, unskilled or both, and as a result their survival rate is low. The Brotherhood Outcasts rededicated their lives to the Brotherhood of Steel's original mission: the acquisition and preservation of lost technologies, operating out of Fort Independence.
===Project Purity, the Enclave, and Broken Steel===
When the Brotherhood discovered Project Purity, based inside the Jefferson Memorial, they decided to help defend the scientists that worked on the project from the frequent super mutant attacks. The goal was simple and beneficial: huge amounts of pure, non-radioactive water for the Capital Wasteland. The only problem was that large-scale tests of the project were always unsuccessful. As time went on, and super mutant attacks became more frequent, the Brotherhood became disinterested with the project. In 2258, Lead Scientist James's wife, Catherine, died in childbirth, and James abandoned the project to find a safe haven for his new child, and the project collapsed. The Brotherhood focused on fighting the super mutant threat for the next two decades, while also attempting to also learn of their source.
In 2272, a man by the name of Three Dog set up a news/music radio station inside the middle of the D.C. ruins, and the Brotherhood struck a deal with him. As stated by Sentinel Lyons "The Brotherhood needed a roof over their heads, and the guy here needed to not get his head blown off. It's a mutually beneficial relationship." The Brotherhood continues to use the GNR building as a "port in the storm."
Eventually, James' child emerges from Vault 101 to find their father, who wants to restart Project Purity, in 2277. A science team is brought together, and repairs are started. Soon though, the Enclave's forces show up, and storm the purifier. Colonel Autumn demands that the project be handed over to the government, but James adamantly states that Project Purity is private and intended to benefit all the people of the Capital Wasteland. To make a point, Autumn shoots the scientist in the room. James then sacrifices himself by flooding the control room with radiation and killing himself, along with the Enclave soldiers, but Colonel Autumn survives.
The remaining scientists and the Lone Wanderer manage to go through the old Taft Tunnels that link the Jefferson Memorial to the Citadel at the Pentagon, with only the Lone Wanderer to defend them from any Enclave soldiers, or feral ghouls along the way. When they reach the end, a Brotherhood of Steel member will make a final stand with the Wanderer against a final horde of feral ghouls, and get the scientists topside to safety. Once there Dr. Li demands that Elder Lyons opens the gate to the Citadel and let them in, which he does so promptly.
Once inside, Elder Lyons begins to contemplate the threat the Enclave now poses. The Lone Wanderer is sent to Vault 87 to locate a G.E.C.K. that is necessary to start the purifier if nothing else than to keep it away from the Enclave. Meanwhile, the Brotherhood gears up for war, modifying their weapons and armor in preparation for fighting the Enclave. Scribe Rothchild teams up with Madison Li on the Liberty Prime robot, and together manage to solve the massive automaton's power problems.
Meanwhile, the Lone Wanderer battles their way through the dangerous Vault 87 and obtain the GECK, also learning that Vault 87 is the source of the D.C. super mutants. They are captured by agents of the Enclave, and the GECK is installed in the purifier. They are then transported to Raven Rock, an Enclave command base, and then interrogated by Colonel Autumn for the activation code, but is interrupted by President Eden, who requests a meeting with them. Colonel Autumn soon orders the Enclave soldiers to attack the Lone Wanderer regardless of the president's orders, and they must fight their way to the president. Once the two finally meet, Eden asks the player character to install a modified FEV virus dispenser in the purifier, as a way to cleanse the Capital Wasteland of all mutations so that only "pure strain" humans like those in the Enclave and the vaults will survive. The player character is forced to leave with the virus in hand but has a chance to "blow up" Eden and Raven Rock if they so choose.
Once the Lone Wanderer makes it back to the Citadel, Sentinel Lyons asks her father permission for an assault on the purifier, which he denies, until the Lone Wanderer tells Elder Lyons of the current situation. Elder Lyons then asks the player character for any important information before proceeding. At this point, they can hand over the Modified FEV (positive Karma), tell the elder about the super mutants and Vault 87 (positive Karma), and about the current status of the Enclave (no Karma). Then the elder asks Rothchild whether or not Liberty Prime is ready to go into battle. Rothchild is skeptical as he'd only just gotten it operational but ultimately agrees that if it's not yet fully ready then it won't matter in the long run. Sentinel Lyons recruits the Lone Wanderer as an honorary member of the Pride, and together they set out for the Memorial.
Liberty Prime easily clears the way through all Enclave forces, clearing a path for the Pride. Once inside the Jefferson Memorial, the Lone Wanderer and Sentinel Lyons make their way through the last of the Enclave forces and eventually confront Colonel Autumn. The Lone Wanderer's can choose the ultimate outcome, but regardless the two make it to the control room whereupon Dr. Li tells them that something has damaged the purifier, that it must be activated now, and that the current radiation levels would kill whoever enters the room to carry out the activation. The outcome here is also dependent on the choices of the Lone Wanderer, and either someone goes inside to activate the purifier, only surviving if the Broken Steel add-on is already installed, or no one goes in and everyone within the room dies. Likewise, at this point, the Lone Wanderer can secretly use the FEV to poison the water.
With the purifier up and running, the Brotherhood takes control and begins distributing the clean water throughout the wasteland with Scribe Bigsley overseeing operations. Also during this time, the Brotherhood begins systematically destroying all remaining Enclave outposts in the wasteland with Liberty Prime spearheading the assault (even destroying Raven Rock if the Lone Wanderer had not done so already). During this time, the Brotherhood also begin to reverse-engineer the Enclave's plasma weaponry, removing that advantage for their enemies. Two weeks after the assault on Project Purity, the Lone Wanderer awakens in the Citadel's clinic and is greeted by Elder Lyons. Scribe Rothchild updates the Lone Wanderer on the current situation on the war between the Brotherhood and the Enclave, then directing the Lone Wanderer to journey to Rockland to help with a Brotherhood attack on an Enclave communications facility.
The Lone Wanderer makes it to the Rockland car tunnels, and assist Paladin Tristan, and a squad of Brotherhood members, and Liberty Prime in the attack. The Enclave forces are decimated, and Liberty Prime manages to literally punch a hole through the Enclave's defenses, giving the Brotherhood an access point. Then, Liberty Prime detects a signal and orders the Brotherhood forces to retreat. Soon after the area is destroyed, along with Liberty Prime, by an orbital bombardment from a weapons satellite ordered by the Enclave, leaving the Brotherhood shaken. Paladin Tristan orders the Lone Wanderer to lead a squad of Brotherhood members to find out what had happened.
At the Citadel, the Brotherhood members discuss the orbital assault. Moments before the attack they had been crushing any Enclave resistance, and now they have lost their biggest weapon, and are facing a new weapon they know nothing about. In addition, it is certain that the Enclave will counterattack, especially since the Brotherhood was the one to instigate the war. When the Lone Wanderer comes back from the Rockland Satellite Station, they deliver some encrypted data for Scribe Rothchild to decrypt, who is aghast at all the hard work that went into restoring Liberty Prime, only to see it all go to waste. Paladin Tristan then sends the Lone Wanderer to the Old Olney Powerworks for a Tesla coil, so the Brotherhood can recreate Liberty Prime's Liberty laser, the only effective defense the Brotherhood had against the Enclave's vertibirds.
The Lone Wanderer does so, with a prototype device made by the Brotherhood meant to jam the signal the Enclave uses to control deathclaws. The Lone Wanderer makes it to Olney Powerworks, encountering many deathclaws, Enclave forces and robots, but eventually, they make it to the center with a functioning Tesla coil in the middle. With the Tesla coil in hand, the Lone Wanderer makes it back to the Citadel and hands it over to the Brotherhood scientists there, and is then ordered to make it to the Adams Air Force Base via the Presidential Metro. When the Lone Wanderer enters the Air Force Base, they open up a supply crate, containing ammo and a working Tesla cannon. When opening the crate, the Brotherhood receives a signal to commence attacking the Air Force Base, so the Lone Wanderer can make their way through the Enclave forces and open the way to the Mobile Base Crawler. The player character makes it to the top of the Mobile Base Crawler and has a choice to either launch the Enclave's last orbital ballistic payload on either the Mobile Base Crawler, setting back the Enclave in the Capital Wasteland severely, or on the Citadel, thus devastating the Brotherhood of Steel. Once outside, a Brotherhood squad, led by Sarah Lyons if she survived Project Purity, pilots a stolen vertibird to take the Lone Wanderer back to the Citadel.
In canon, the Lone Wanderer destroys the MBC, and the Enclave is permanently removed as a threat from the Capital Wasteland. The East Coast Brotherhood moves on back to normal, taking out the mutants and raiders. 
With the Brotherhood in control of Project Purity (providing access to clean, purified water), one vertibird and vast amounts of technology and equipment acquired from the Enclave after the successful war, and access to local recruitment and manpower, the East Coast Brotherhood is effectively in control of the Capital Wasteland. The original Brotherhood however in California, is more weakened than before by 2281.
