There are four main factions in Fallout 4 that you can side with during the main story, and the Brotherhood of Steel is one of the most popular because of their relevance in previous Fallout games and their powerful technology. They are a very complex faction. However, their morals in Fallout 4 are questionable.
There are many things that you won't get a chance to discover if you side with a faction other than the Brotherhood of Steel, especially surrounding the background of the branch of the Brotherhood that is present in the Commonwealth during the events of Fallout 4.
10 The Brotherhood Of Steel Have Jetpack Technology
Jetpacks are a craftable power armor upgrade in Fallout 4, and many different perks are required to craft one of these futuristic pieces of technology. However, if you side with the Brotherhood of Steel, then they will give you a jetpack upgrade for your power armor upon defeating the Institute.
It is interesting that the Brotherhood of Steel has access to jetpack technology since they don't use it in Fallout 4. If they had used power armor with jetpacks during the events of the main story, then they would have had a very great advantage against the Institute and Railroad.
9 The Boston Airport Secret
There is a secret hidden in the ruins of the Boston airport, and this secret is that a Brotherhood of Steel member named Clarke has been stealing supplies from the faction to bring to a group of ghoul NPCs.
This Brotherhood of Steel agent doesn't believe that killing ghouls for the sake of it is morally right, and he wants to defend their right to live, even if they are feral. It's easy to miss this side quest even if you do join the Brotherhood of Steel since it is optional, but it is one of the most morally interesting quests in Fallout 4.
8 The Brotherhood Of Steel Train Child Soldiers
Although there were Brotherhood of Steel child soldiers present in Fallout 3 to an extent, it made a lot more sense considering that they had an entire Citadel to protect them from outside forces. However, allowing children to make the journey to the Commonwealth with them is one of the Brotherhood of Steel's more questionable decisions in Fallout 4.
If you don't side with the Brotherhood of Steel, then you probably don't know that there are children inside of the Prydwen since it is never talked about anywhere else in the game.
7 Paladin Danse Dislikes Ghouls And Synths
There are many Brotherhood of Steel members that dislike ghouls and synths; however, Paladin Danse may initially strike you as a more accepting person based on your friendly encounter with him early in Fallout 4.
If you take Paladin Danse on as a companion, then you will quickly learn that he dislikes both ghouls and synths immensely. A specific example of this is how he reacts to the Vault-Tec Rep that has been turned into a ghoul; Paladin Danse makes a rude comment towards him and about how someone should put him out of his misery.
6 There In A Nuclear Missile Silo In The Glowing Sea
Deep within the Glowing Sea, there is a nuclear missile silo that was abandoned after the Great War because of the high levels of radiation surrounding the building. This location is of vital importance for completing the Brotherhood of Steel main questline; however, it isn't used for anything else in Fallout 4.
As such, it's easy to completely miss out on this location since it doesn't contain anything of value if you don't side with the Brotherhood of Steel during the main questline.
5 The Brotherhood Of Steel Uses Intimidation Tactics To Steal Food From Farmers
Unfortunately, the Brotherhood of Steel isn't nearly as noble as they were in previous Fallout games. The Brotherhood regularly plans missions to farms located around the Commonwealth, and they extort the farmers for a share of their crops.
You can even partake in stealing food from these farmers if you talk to Proctor Teagan on the Prydwen after joining the Brotherhood of Steel. He will then give you a quest to go intimidate or persuade the farmers into sharing their crops.
4 Arthur Maxson Got His Scar From Killing A Deathclaw When He Was Thirteen Years Old
If you didn't side with the Brotherhood of Steel and only interacted with Arthur Maxson during combat, then you may wonder where he got the large scar that covers his face. This scar has a fascinating story behind it; Maxson killed a deathclaw by himself when he was 13 years old, and although he won the fight, the deathclaw managed to wound him and leave a scar.
This tale is one of the most interesting stories about a Brotherhood of Steel member, and it may make you respect Arthur Maxson a bit more if you didn't like him as a character otherwise.
3 The Brotherhood Of Steel Is Growing Nirnroot
Nirnroot is one of the most important alchemy ingredients in The Elder Scrolls franchise, and it is widely known for the sound that it gives off when you are within a short radius of one of these plants.
If you board the Prydwen and look around a bit, then you will find that the Brotherhood of Steel is growing their own nirnroot. However, this plant is a purple-like color instead of green, and it is considered to be experimental.
2 Sarah Lyons And Elder Owyn Lyons Died Before The Events Of Fallout 4
Both Sarah Lyons and Owyn Lyons passed away between the events of Fallout 3 and Fallout 4. These two characters were very popular among the Fallout franchise fanbase because of their actions in Fallout 3 and their unique personalities.
This information is revealed on the Prydwen, and you cannot access it unless you join the Brotherhood of Steel. Sarah died during combat, and Owyn most likely died from old age.
1 Paladin Danse Is A Synth
In what is widely considered to be one of the best plot twists in Fallout 4, Paladin Danse is actually a synth. This fact is revealed during the Brotherhood of Steel main questline.
It may come as a shock for some to hear that Paladin Danse is, in fact, a synth, especially considering his dislike for them. However, he was created by the Institute and even has false memories, which is why he doesn't know that he is a synth and has believed himself to be a human this entire time.
The student who acquired the drive has been given a life sentence and others who watched it will do five years hard labor.
