Brotherhood of Steel (Fallout)

The Brotherhood of Steel, originally led by Elder Roger Maxson, is the founding chapter of the Brotherhood of Steel, appearing

Background
The Brotherhood at Lost Hills faced a threat in the form of super mutants. Training was stopped and Vree autopsied the specimens to determine their origin. Scouts were sent out to determine the threat level, and those that returned reported encountering mutants, "strange beings, all muscle with burnin' eyes." The Brotherhood was able to destroy the threat alongside the Vault Dweller.

Meanwhile, the Water Merchants of the Hub attempted to barter a large quantity of water for a weapons stockpile. Although the Brotherhood turned down the offer, the merchants attempted to take the weapons regardless. The thieves were caught, but the Brotherhood Elders voted down a retaliatory expedition.

The Brotherhood learned of the technologically advanced Enclave and attempted to observe the group from afar to learn as much as they could. The Brotherhood had waned in influence and power over the preceding years, now unable to deal with the Enclave by force. The Enclave had access to vertibirds, a technology that the Brotherhood lacked. In order to learn more about them, the Brotherhood created a network of outposts to observe Enclave activity, keeping a low profile while doing so.

Appearances
