The Brotherhood First Expeditionary Force, currently referred to as the Appalachian Brotherhood of Steel,[4][Non-canon 1] is a faction comprising Brotherhood of Steel soldiers sent from Lost Hills to re-establish contact with the original Appalachian Brotherhood. Ever since reaching West Virginia, they have taken the mantle of their brothers and sisters in protecting and gathering technology from all around Appalachia.



Following the Great War, Captain Roger Maxson used surviving satellites to communicate with survivors across the United States of America, attempting to recruit them under a common cause, which eventually led to the formation of the Brotherhood of Steel.[5] He succeeded in contacting a former colleague, Elizabeth Taggerdy, who formed a Brotherhood chapter with her Army Ranger unit in Appalachia. Contact was lost with Taggerdy when the satellites failed years later, and the Western Brotherhood was left unaware of the outcome of the Appalachian chapter's war against scorchbeasts and the accompanying Scorched Plague.[6]

The former US National Guard and current Paladin Leila Rahmani requested an expedition to Appalachia.[3] After many years, her request was finally approved by High Elder Roger Maxson[2] and the Council of Elders, and she was appointed as its leader.[3] One of the expedition's critical members was to be Scribe Hailey Takano, but due to health issues, she was not able to take part and was replaced by her student Scribe Odessa Valdez, who had volunteered to take her teacher's position.[7] Three knights were given the task to accompany them, including Alan Connors, another National Guard and close friend of Rahmani, Matthew Thornberry, and Daniel Shin. The expedition's goals were to investigate valued technological sites on their journey across the United States and upon arriving at Appalachia, set up camp at the ATLAS Observatory to investigate the facility's true purpose. In addition, they were to discern the fate of the original Appalachian chapter and to take their mantle if necessary, including the protection of Appalachia's inhabitants. Following that, the group would report their findings back to command.[8][9]


Paladin Rahmani led the First Expeditionary Force east from the Lost Hills bunker. Upon reaching the Sierra Nevada, they encountered a group of raiders with a cache of highly advanced weaponry, torturing a captured unit of Brotherhood soldiers.[10] Knight Thornberry personally rescued the soldiers and recovered the technology. This earned the respect of Rahmani, who charged him with the task of safely guiding the wounded soldiers back to Lost Hills and seeing to their recovery.[10]

After crossing the Rocky Mountains, radio communications were lost between Lost Hills and the Expeditionary Force.[11] Over the course of the following months, the scribes at Lost Hills tried to reach the group, but to no avail. Command sent various encrypted radio messages, first while estimating their location near Lincoln, and later ordering the expedition to divert from their primary goal.[11] Another attempt was made, estimating their location as east of the Mississippi River, and ordering them to proceed with their original mission in order to establish contact at the target location in Appalachia.[11]

The next radio message was recorded off the record by Elder Roger Maxson via a private channel to Paladin Leila Rahmani. He believed the paladin understood the value and purpose of the Brotherhood of Steel, and despite their disagreements, Maxson hoped the lack of communication was simply due to the inability of answering back. Otherwise, the radio silence would be taken as desertion by the Council of Elders, and Maxson would be overruled in regards to what to do with the expedition and wouldn't be able to defend her anymore.[11]

After more than three months without any contact with the First Expeditionary Force, Elder Maxson sent a last official message to Paladin Rahmani.[11] The scribes estimated they should have already entered the borders of West Virginia and be close to their target destination at the ATLAS Observatory. Maxson's orders for the expedition were to reestablish contact with Lost Hills right after securing the observatory, providing a full report on their whereabouts during their journey, and to represent the Brotherhood in Appalachia.[11]

At some point during their months-long journey, Rahmani and the rest of the First Expeditionary Force encountered a settlement under threat of raiders.[12] Rahmani decided to equip them with government-issue weaponry they had found in a military facility in the Midwest that they had initially intended to keep for the Brotherhood. However, the weapons proved useless against the raider force, as the settlement was wiped out, with only two survivors.[12][13][14] Because of the loss of Knight Alan Connors and the raiders actually getting strengthened by the looted weapons, the incident would set off a division between Rahmani and Shin, with Shin wanting Rahmani to stand trial with the Council of Elders.[15]


Not far from West Virginia, while approaching their destination, Paladin Rahmani broadcasted a message across Appalachia, announcing their arrival and their objective of taking over the ATLAS Observatory, warning any possible occupants to leave the facility.[16] She announced they were going to help the people of Appalachia by providing aid and protection, and that any help would be welcome. Her voice could be heard across the region, becoming more audible with each passing week.[16]

Russell Dorsey, an enthusiast of the old Appalachian Brotherhood, had heard the radio message and was already at the observatory with several Protectrons to aid in its fortification.[17] He, alongside the Vault Dwellers, managed to clear the exterior of the facility and prepare it for the arrival of the expedition.[17][18]

By the time the First Expeditionary Force reached the ATLAS Observatory, having had crossed over two thousand miles of wasteland over the course of many months, the group itself was made up of only three of the original five Brotherhood personnel.[19][20][21] In addition, they had informally recruited many initiates and hopefuls along the way. After establishing their base of operations, they renamed the observatory to Fort Atlas.[22]

Steel Dawn

During the first months in West Virginia, the new Appalachian Brotherhood established outposts around Fort Atlas and the Wayward,[23] and sent patrols composed of recent initiates and hopefuls to different areas of the region in search of technology.[24] The Brotherhood chapter was also soon inoculated against the Scorched Plague.[25]

Despite one of their primary missions being to reestablish contact with Lost Hills, the group was unable to do it due to the loss of their long-distance communications transmitter at the hands of raiders.[8] Rahmani expresses hesitation to establish contact, as she fears it would result in having their titles stripped and their influence rendered illegitimate.[26] Despite the fact that re-establishing contact was an order in and of itself, Rahmani believes that they could continue on as a sanctioned offshoot nonetheless, able to spread "authority and goodwill across the nation."[26]

  4. Knight Shin: "I have every intention of forging a better future, but this is not the way. You've broken your Oath, Paladin. No... That title no longer belongs to you. With your link removed from the Chain, I am the highest ranking officer present. All members of the Appalachian Brotherhood of Steel now answer to me."
    (Daniel Shin's dialogue)
  5. Formation of the Brotherhood of Steel
  6. Elder Maxson's final conversation
  7. Fort Atlas terminal entries; Scribe Valdez's terminal, Brotherhood: Chapter Scrolls, SCRIBE Valdez, Odessa
  8. 8.0 8.1 Vault Dweller: "Why did the Brotherhood come here?"
    Knight Shin: "The First Expeditionary Force was tasked with investigating several valued technological sites across the U.S., concluding at the ATLAS Observatory. From here we would report back on the fate of the preceding Appalachian Chapter, carrying on the Brotherhood's mission in their stead if need be. Or we would have done that report, if we still had a working long-distance transmitter. We have Raiders to thank for that one."
    (Daniel Shin's dialogue)
  9. Vault Dweller: "Why did you come to Appalachia?"
    Scribe Valdez: "We're here to help the people of Appalachia, and to catalog any technological discoveries we find. We set up Fort Atlas to that end. This old observatory has a wealth of technology to discover, and is a good staging point for future operations. We also want to learn the fate of the old Appalachian chapter of our order. MIA, presumed KIA."
    (Odessa Valdez's dialogue)
  10. 10.0 10.1 Fort Atlas terminal entries; Scribe Valdez's terminal, Brotherhood: Chapter Scrolls, KNIGHT Thornberry, Matthew
  11. 11.0 11.1 11.2 11.3 11.4 11.5 Encrypted broadcasts
  12. 12.0 12.1 Vault Dweller: "What was this incident?"
    Paladin Rahmani: "You must recall the Brotherhood weaponry we tasked you with retrieving these last few missions. We had claimed the entire cache from a military facility in the Midwest. It was meant to stay under Brotherhood protection. Until we came across a town under threat of a massacre by the Raiders. We equipped the townspeople with the weapons, and fought by their sides. It was the only way to give them a chance. But it wasn't enough. The Raiders won. They took possession of the weapons. And they've been running wild ever since. It is my belief that we must learn from our mistakes. But Knight Shin hangs onto them. He cannot move forward until he confronts the past, until he lays our guilt on display for the Elders. I say that we can - that we must - move forward on our own."
    (Leila Rahmani's dialogue)
  13. Vault Dweller: "Is what happened really such a big deal?"
    Paladin Rahmani: "You weren't there, Initiate. It was... harrowing. Those civilians trusted us to save them. We... lost one of our own as well. Knight Connors. May he rest in peace. We disobeyed orders, handing out those weapons instead of safeguarding them. Perhaps it would have been forgivable, had we succeeded. But the Elders would take this failure as proof of the danger of unrestrained technology. They would double down on the fearful conservatism I've tried so hard to steer them away from. We cannot let that happen. At this stage, the Brotherhood still has a chance to be something better."
    (Leila Rahmani's dialogue)
  14. Vault Dweller: "As Paladin, how could you let this incident happen?"
    Paladin Rahmani: "Yes, I am responsible for the final outcome of all operations performed by this group, regardless of individual choices made. What happened is an irreparable tragedy. I carry the weight of the lives that were lost with every step I take. But I cannot allow it to stop me."
    (Leila Rahmani's dialogue)
  15. Vault Dweller: "Tell me about the incident that split Rahmani and Shin."
    Scribe Valdez: "Right... Those weapons you've been chasing? We found them in a government facility on our way to Appalachia. We were supposed to keep them to ourselves - that's how we operate - but then we ran across a settlement being threatened by raiders. We couldn't just leave them to die. We equipped them with the weapons we found, but it didn't help. It was a massacre. The whole place was wiped out. Everyone was killed, including Knight Connors, one of our own. The only survivors were two children we brought back with us, Marcia and Max. Knight Shin believes it's our duty to report this incident to Elder Maxson. Paladin Rahmani feels we'd be punished just for trying to help."
    (Odessa Valdez's dialogue)
  16. 16.0 16.1 Brotherhood broadcast
  17. 17.0 17.1 Fortifying ATLAS
  18. Fort Atlas terminal entries; Paladin Rahmani's terminal, LEILA RAHMANI'S PERSONAL LOGS, Arrival
  19. Leila Rahmani: "Need to have Valdez take another look at my armor. 2,000 miles of hiking's put some real wear on it."
  20. Vault Dweller: "Where did your group come from?"
    Scribe Valdez: "California, all the way across the continent. I've read that people used to fly that distance in a few hours, but the trek took us months. Maybe eventually we'll get flying again, but for now it's an arduous journey."
    (Odessa Valdez's dialogue)
  21. Vault Dweller: "How many of the Brotherhood are here?"
    Russell Dorsey: "Well, aside from the Initiates and hopefuls they recruited along the way...just three. I was expecting more, honestly, but Paladin Rahmani said three was plenty to start a new chapter. With the recruits they have already, she's right."
    (Russell Dorsey's dialogue)
  22. Fort Atlas terminal entries; Scribe Valdez's terminal, Scribe Valdez - Personal Logs, ATLAS Observatory
  23. Outposts near Fort Atlas and the Wayward.
  24. Random encounter with Brotherhood soldiers.
  25. Vault Dweller: "Everyone here needs to get inoculated, or else you'll turn into Scorched.
    Paladin Rahmani: "All of us have taken the inoculation. But thank you for inquiring. It means a lot to me that the peolpe of Appalachia care for the well-being of others."
    (Leila Rahmani's dialogue)
  26. 26.0 26.1 Vault Dweller: "Contacting the Elders might destroy us? There's something you're not telling me."
    Paladin Rahmani: "Something happened during our journey to Appalachia. A mistake that cost the lives of an entire town, and likely countless more. If Knight Shin gets an opportunity to speak with the Elders, he will confess to this incident, and to us breaking their direct orders. We'll have our titles stripped, our influence rendered illegitimate. Everything we worked for here will be gone. But if circumstances prevent us from establishing contact, we will continue on as a sanctioned offshoot of the Brotherhood of Steel. We will be able to spread its authority and goodwill across the nation. Is that not something worth fighting for?"
    (Leila Rahmani's dialogue)
