Brotherhood of Steel (Fallout BOS)

The Brotherhood of Steel is an expeditionary force sent to the Texas under orders from High Elder Rhombus and is the playable faction in Fallout: Brotherhood of Steel.

Background
After the death of John Maxson, Rhombus, the head of the Brotherhood's Paladins, became the new High Elder. After the death of the Master, the Brotherhood of Steel helped the other human outposts of the former American Southwest drive the mutant armies away with minimal loss of life on both sides of the conflict.

However, a super mutant faction under the leadership of Attis moved east and attempted to recreate the mutant army in Texas using the Vault-Tec Corporate Vault. Rhombus, despite some criticism from the ruling council of the West Coast Brotherhood of Steel, started a crusade against the still existent threat of the super mutant army, now led by Attis.

They arrived in Texas in 2208, and discovered an abandoned facility, which they turned into a Brotherhood of Steel Automated Training Center. Their principal mission was to eradicate the menace of all super mutants. The group was successful in their quest, destroying Attis and his army at the ghoul city of Los at what was subsequently called the Brotherhood-Attis War.

Behind the scenes
In the canceled Fallout: Brotherhood of Steel 2, the Brotherhood would have expanded into Fort Worth and the Alamo.
