Brotherhood of Steel (Fallout: New Vegas)

The  is a chapter of the Brotherhood of Steel active in the Mojave Wasteland. Its headquarters and only remaining base is the Hidden Valley Bunker. As of 2281, the chapter is finding itself in great decline, and is led by Elder Nolan McNamara.

Discovering HELIOS
The chapter was first formed by Elijah, a scribe who was promoted to the rank of Elder. It's purpose was to secure the Hoover Dam for the Brotherhood of Steel. After entering the Mojave, Elijah began to show great interest in HELIOS One, and despite the various outcries from the Paladins that the site was impossible to defend, the Elder decided the vast potential of the site was worth the risk. Declaring that HELIOS would become the chapter's main base, the rest had no choice but to follow. Unfortunately for the Brotherhood, the New California Republic had reached the Mojave by 2273 and had taken Hoover Dam.

War with the NCR
In 2274, the NCR had officially set up a base at Camp McCarran. With a main base now set up, the NCR soon set it's sights on the HELIOS One solar plant. Elijah, still believing that the plant contained an unprecedented military advantage, refused to leave the plant, and forced the paladins to continue defending it.

Outnumbered 10 to 1 by NCR troops, constant skirmishing arose. Despite the Brotherhood being in control of far superior weapons, such as laser rifles, the Brotherhood had no reinforcements, and after each fight lost more and more soldiers. Paladins continued to urge the Elder that they should retreat back to the bunker, but Elijah didn't listen. Eventually, when the casualties reached too high, Elijah fled without warning, Veronica being the only person with any contact.

With no leader, Nolan McNamara took up leadership of the chapter. Leading a counterstrike, the remaining Paladins and Scribes fought their way out of the facility and back to the bunker, where they'd reside for years. McNamara, going against the wishes of most of the inhabitants, declared an official lockdown on the bunker, no-one was allowed out, and anyone already outside wasn't allowed back in.

Current Status
The chapter operates a policy of strict isolationism, no outsiders are allowed anywhere near the bunker, and anyone found near it is killed. The only people granted access are patrols, scouts, and Veronica, the latter being to keep her out of everyone's hair. Although they now have their numbers back up to pre-HELIOS, NCR has also multiplied rapidly, and was thought to be a much greater risk than before. The only way the bunker has grown is through procreation, and as thus any relationship that doesn't end this way is forbidden, much to Veronica's displeasure, while outsiders joining the group is unheard of. The paladins have only remained sharp thanks to the Virtual reality simulators and a firing range.

Indeed, the Courier is the only outsider to have visited the bunker, and thus can determine the fate of the ill-fortuned chapter. Whilst Mr. House and Caesar's Legion both want the Brotherhood eradicated to ensure there is no interference, the NCR are a bit more flexible, and the Courier can instead negotiate a truce with the Brotherhood, which will ensure the Brotherhood's survival in the Mojave for some time.

Technology

 * The Brotherhood uses a mixture of both the T-45d and T-51b models of power armor, with the T-51b being much more widely used. Their weapons are all extremely advanced, with tri-beam laser rifles being almost standard issue to the standard guard, while Gauss rifles are also used in high volume.
 * Scouts continue to find weapons in the Mojave, resulting in many unused weapons stored in the Brotherhood armory.
