And so the lockdown has been extended. To go outside would be the death of us all.Nolan McNamara

The Mojave chapter[2][3] of the Brotherhood of Steel is a minor faction encountered in the Mojave Wasteland in Fallout: New Vegas. Reduced down to the size of a single bunker after a devastating offensive by the New California Republic, the chapter under the leadership of Elder Nolan McNamara bides their time, careful to keep themselves hidden even as they fracture from the inside.


Taking HELIOS[]

While officially sent out from Lost Hills to secure Hoover Dam in the former state of Nevada,[4][5] the formation of the Mojave chapter was mainly a result of disagreements within the council of elders. Elijah, a former scribe who had achieved elder status, pushed for the development of new technologies as opposed to the Brotherhood's typical recovering of pre-War technology, which put him at odds with the more conservative members of the council. As Elijah proposed developing new ethically questionable weapons somewhere around the early 2260s,[6] the elders decided to send him away on a mission of uncertain success, ostensibly to expand Brotherhood interests further into the east, but secretly to get his radical ideas out of earshot.[7]

Once they had reached the Mojave Wasteland, the new chapter discovered an intact military bunker in Hidden Valley, repurposing it as one of their forward operating bases. From there, the Brotherhood's scouting turned up the intact solar power plant at HELIOS One. Elijah, already considered unorthodox by some within his own chapter for his focus on improving technology rather than simply preserving it, immediately ordered for the plant to be garrisoned and converted into the Brotherhood's headquarters despite objections from almost every paladin in the chapter.[1]

The Mojave chapter experienced several years of freely operating in the wastes, carrying out many reclamation missions without serious opposition from their neighbors. However, the balance of power shifted in 2273, when a large contingent of NCR Army troops entered the region from New California and occupied Hoover Dam before the Brotherhood could fulfill their original mission.[Non-game 1]

As a result of Elijah's obsession with HELIOS One, coupled with their failure to occupy Hoover Dam themselves and the subsequent need to secure their base against the NCR's encroachment, the Brotherhood ignored the entry of the Van Graffs into the Mojave despite their reputation as highly successful energy weapon distributors. Against objections from his subordinates, Elijah's order was clear: leave the Van Graffs alone.[8]

Conflict with the NCR[]

Main article: NCR-Brotherhood War

By 2274, the NCR had officially set up a headquarters of their own at the former McCarran International Airport. From there, Army forces began spreading out into the rest of the Mojave themselves, ultimately leading to the discovery of the Brotherhood installation at HELIOS One. Elijah, still believing that the plant contained an unprecedented military advantage, refused to abandon the Brotherhood's position in spite of the NCR's approach, and forced the Paladins to continue defending it. For two years, the Brotherhood waged a guerilla war against the NCR while Elijah continued to occupy himself with unlocking the alleged secrets within HELIOS.[Non-game 1]

In 2276, the NCR moved to put an end to the Brotherhood's resistance and launched Operation Sunburst as a final offensive to capture HELIOS One. Despite the Brotherhood's technological advantage with energy weapons and power armor, they lacked the numerical advantage of the NCR and were gradually worn down by repeat attacks. By the time the retreat signal was given by Paladin McNamara, more than half the chapter had been wiped out. In the midst of the Brotherhood's exodus, Elijah disappeared without a trace. Guided by McNamara, the Brotherhood survivors retreated to the Hidden Valley bunker, while the NCR regrouped at the newly occupied HELIOS One. By the conclusion of Operation Sunburst, the Brotherhood's position in the Mojave was crippled, but not defeated.[Non-game 1][9]

With their leader vanished to the winds, Head Paladin McNamara stepped up and took the reigns. Out of fear of Hidden Valley being discovered and destroyed, the new Elder McNamara heavily restricted surface activity, locking down the bunker and limiting outside assignments to occasional reconnaissance missions and high-value raids, as well as necessary supply runs by dedicated couriers. All operations were to take place at night, and combat engagement of NCR forces is strictly forbidden. Though the Brotherhood's ascetic lifestyle prepared its member for living in the bunker's confined spaces at length, the stress of their position began to chip away at the chapter's cohesion.[Non-game 1]

Internal conflict[]

By 2281, the Mojave chapter operates on a policy of strict isolationism: no outsiders are allowed anywhere near the bunker, and anyone found near it is killed. The only people cleared for surface access are nightly patrols by heavily armed paladins, lightly-armed scouts, and procurement specialists securing food, water, and other necessities. All remaining members of the chapter are direct descendants of the original Brotherhood from the west, with no outside recruitment from the neighboring wasteland populations unlike other chapters.[10] Combined with the culling of their numbers by the NCR and failure to recover its strength at the same time as the Republic's hold on the Mojave has only increased (with the number of troops alone increasing five times),[11] as well as extended isolation under the elder's orders taking its toll, the chapter's future situation is precarious. While virtual reality simulators and firing range exercises keep the Knights and Paladins (many of whom have only virtual combat experience) sharp, the chapter has been left cut off from the rest of the Brotherhood.[12]

Without any avenues of reinforcements or long-term solutions apart from remaining in hiding underground, the chapter's prospects are doomed. The persistence of the lockdown has led some among the chapter, chief among them Head Paladin Edgar Hardin to seek out steps to ousting the Elder. Though Hardin has sympathizers who support his goal of ending the lockdown, he has not made any overt moves against the Elder out of respect for McNamara's actions in safeguarding the Brotherhood following the loss of HELIOS One.

Beyond the walls of the bunker, the major factions vying for control of the Mojave have their own reservations about the Brotherhood's presence. While Mr. House and Caesar want the Brotherhood dead, the NCR is a bit more flexible, even if some in their ranks would rather also see them wiped out.


Main article: Brotherhood of Steel

The Brotherhood of Steel is a militant organization devoted to the preservation of pre-War technology and human knowledge. Their professed mission is to preserve pre-War technology and human knowledge for the benefit of future generations. In practice, its definition of technology is selective to its own needs, ignoring basic but potentially useful technologies (genetic modification of crops and civil engineering, for example) in favor of combat technology such as energy weapons and power armor; and even now, nearly two centuries after the Great War, the Brotherhood zealously restrict the use and knowledge of such technologies to its own membership.[Non-game 1]

Foreign relations[]

Since their heavy losses to the NCR during the NCR-Brotherhood War, the Mojave chapter has kept its contact with the outside world to a minimum, due to heavy casualties. Other than a few scout patrols and supply scavengers, such as Veronica Santangelo, that come in and go back out at night, no members are allowed to leave the secure bunker and people outside of the Brotherhood entering or leaving the Hidden Valley base is unheard of.

Interactions with the player character[]

Because of the Hidden Valley lockdown, only a select few are able to leave the bunker. Because the player character is not an official member of the Brotherhood, they become a natural choice to find lost Brotherhood patrols without jeopardizing other members of the organization. Depending on the Elder leading the Brotherhood, one can aid the Brotherhood further by tapping into the radar systems of Black Mountain or eliminating the Van Graffs, who hold a large cache of energy weapons.


Fallout New Vegas T-51b

The Mojave Wasteland chapter of the Brotherhood of Steel utilizes a mixture of both the T-45d and T-51b model of power armor, with the T-51b used predominantly. Their weapons are energy-based, with tri-beam laser rifles being almost standard issue to the guards and patrols in and around the Hidden Valley bunker, while Gauss rifles are also widely used. Scribes use the Laser RCW (including Elder McNamara) or zap glove. Patrols sometimes include heavier weapons such as the Gatling laser. Their scouts continue to find weapons in the Mojave, resulting in many unused weapons being stored in the Brotherhood armory. It seems that the Brotherhood scribes are researching night vision optics and unique project initiatives such as automatic doors.

  • A three- to four-person patrol composed of paladins leaves the Brotherhood bunker in Hidden Valley at around 1:30 - 3:00 AM under cover of the manufactured dust cloud defense, although most, if not all, patrols return to the bunker at sunrise.
  • Over Radio New Vegas, Mr. New Vegas comments on reports of "hulking individuals" that have been spotted around Hidden Valley after dark.[13]
  • Brotherhood paladins inside the bunker wear mismatched power armor. Although none wear the Brotherhood T-45d power armor, T-45 helmets are worn with Brotherhood T-51b power armor.


The Mojave chapter of the Brotherhood of Steel appears only in Fallout: New Vegas and is mentioned in the add-ons Dead Money and Old World Blues.

Behind the scenes[]

On Bethesda Softworks Forums, Joshua Sawyer stated, "Many years have passed since the events of Fallout 1 and in the time between F2 and F:NV, the western Brotherhood has suffered very heavy losses. Because they are, by nature, insular, replacing their fallen veterans is difficult. Most of the Mojave chapter's paladins are relatively inexperienced. There isn't an army of Rhombuses down there." He also explained that "the Veteran Rangers in the Mojave Wasteland are also the best of a victorious army that are moved in late in the game. The Mojave Paladins are by no means the concentrated elite of the western BoS."

  1. 1.0 1.1 The Courier: "Who is Elijah?"
    Ramos: "Who was Elijah, more like. He was our Elder before McNamara. Bright guy, but just between you and me he was a little off. Our mission is to recover and preserve the technology of the past, but Elijah wanted more. He sought ways to improve upon technology, make it better. When we found HELIOS One, he was like a kid in a candy store. He kept talking about the potential, and a 'grand design, never realized.' He even insisted we set up our base there, against the objection of nearly every paladin. What followed is a whole other story."
    (Ramos' dialogue)
  2. Hidden Valley bunker terminal entries; terminal, Incident #4
  3. Robert House: "Your next assignment is to locate and destroy remnants of the Mojave chapter of the Brotherhood of Steel. The NCR nearly did the job at Helios One a few years ago, but there seem to have been survivors, unfortunately. Given the Brotherhood's fanatical views on technology, they can be counted on to oppose my regime."
    (Robert House's dialogue)
  4. The Courier: "Why is the Brotherhood interested in Nevada?"
    Veronica Santangelo: "It was the Dam, really. We'd heard rumors it was working. Figured we could claim it, put it to use. And... it may also have been partly that our Elder at the time had worn out his welcome. Didn't end up mattering. We got sidetracked at HELIOS One and the NCR took the Dam in the meantime. We're still after it, though. In theory."
    (Veronica Santangelo's dialogue)
  5. The Courier: "Did you follow him from California?"
    Veronica Santangelo: "It was by his request, actually. He cleared it with the other Elders. {To herself} Somehow. They sent him to look into the Dam. There was a time when I'd have begged to follow. Watch him at work."
    (Veronica Santangelo's dialogue)
  6. The Courier: "Do you have any other family in the Brotherhood?"
    Veronica Santangelo: "Just my parents, but they haven't been around for a long time. Dad was a Paladin, Mom was a Scribe. They died in the same battle trying to hold off the NCR from... something. I don't remember what it was. Guess it seemed important at the time."
    The Courier: "Who was this Father Elijah to you?"
    Veronica Santangelo: "I would say he was my tutor, but that doesn't cover it. After my parents passed, he looked after me. The whole Brotherhood brought me up, really, but he made sure of it. I never had a grandfather - not that I knew, anyway - but Elijah was in some ways what I'd imagine a grandfather to be."
    (Veronica Santangelo's dialogue)
  7. The Courier: "Who is Father Elijah?"
    Veronica Santangelo: "He was our Elder when we came East. A wizard with technology, really. His mind just worked that way naturally. Learned a lot from him. But he started having disagreements with the other Elders. The Brotherhood's interest is in old technology. He wanted to explore developing new tech. And there were other ways he wanted to push. Other weapons. Ones with ethics questions attached. Rather than deal with him, they sent him East."
    (Veronica Santangelo's dialogue)
  8. The Courier: "Yes, what is the task?"
    Edgar Hardin: "Back when we were stationed at HELIOS, our scouts reported that a group was establishing itself in the area as a distributor of Pre-War weapons. Our Elder at the time, Elijah, was too concerned with getting HELIOS running and fending off the NCR, so he ordered us to leave them alone. It's time that we correct that oversight, and show this region that the Brotherhood is still a force to be reckoned with. I want you to visit these weapons dealers, this Van Graff family, and make an example of them. Leave no one alive. When the job is done, report back and I'll arrange for a team to clean up the site and retrieve the weapons."
    (Edgar Hardin's dialogue)
  9. The Courier: "Why do you hate the Brotherhood so much?"
    Robert House: "Because they're ridiculous! Because they galavant around the Mojave pretending to be Knights of Yore. Or did, until the NCR showed them that ideological purity and shiny power armor don't count for much when you're outnumbered 15:1. The world has no use for emotionally unstable techno-fetishists. Just wipe them out, will you?"
    (Robert House's dialogue)
  10. The Courier: "Power armor and laser rifles are still effective."
    Veronica Santangelo: "Yeah, but only if you've got bodies to fill the suits. We don't take on new members. We're all descendents from the original Brotherhood. Something's going to have to change, or the empty suits are gonna be all that's left of us."
    (Veronica Santangelo's dialogue)
  11. The Courier: "Tell me about the lockdown."
    Nolan McNamara: "It's a protective measure that was enacted after our defeat at HELIOS. The NCR was hot on our heels, and we wouldn't have survived another encounter. It was decided that we would stay quiet for a time, heal the wounded, and try to come up with a new strategy. However, after we had fully recuperated, our first scouting measures showed that the NCR's presence in this region had only increased in our absence. There are now more than five times the number of NCR troops in the area as when we fought them, and we have half the number we did at HELIOS. And so the lockdown has been extended. To go outside would be the death of us all."
    (Nolan McNamara's dialogue)
  12. The Courier: "One of the few times an Elder was dismissed was due to it."
    Edgar Hardin: "I could be wrong, but I think that's a dead end. McNamara's always followed orders, and we've been incommunicado since fleeing HELIOS."
    (Edgar Hardin's dialogue)
  13. Mr. New Vegas: "Scavengers report hulking individuals moving around Hidden Valley after dusk, but have been unable to identify them due to low visibility."
    (Mr. New Vegas' dialogue)

The battle for HELIOS One (Operation: Sunburst) proved a disaster for the Mojave Brotherhood. More than half its Paladins and Knights were killed. The chapter's leader, Elder Elijah, disappeared without a trace. The Brotherhood was driven from the facility, which suffered extensive damage. Survivors retreated to Hidden Valley.
    Since that defeat, the chapter's leader, Elder McNamara, has restricted activity outside the bunker to occasional reconnaissance missions and high-value raids. All operations take place at night, and engagement of NCR forces is strictly forbidden. Though the Brotherhood's ascetic lifestyle has prepared its members for a sequestered existence better than most, the passivity of their current situation has proved highly stressful."
