Brotherhood of Steel (Fallout 3)

Lyons' Brotherhood of Steel or the Capital Wasteland detachment is a contingent of the Brotherhood of Steel in Washington D.C. The group's headquarters is located in the Citadel, led by Elder Owyn Lyons.

Background
Crossing the country from the West Coast, the group traveled to the region in an effort to recover technology from the eastern cities and bases.

On the way, the group passed through the ruins of Pittsburgh, a chaotic and violent city. In one night, the group swept through the city and eliminated the threats in the area. The contingent saved unmutated children, bringing them along with them as they moved forward, assimilating them into their ranks. This event was named the Scourge, and resulted in one soldier left behind and presumed dead, Initiate Ashur.

Citadel
The Brotherhood intended on recovering the advanced technology and leaving as intended, arriving in the Capital Wasteland in 2255. Elder Lyons realized the extent of a super mutant threat in the meantime and felt it was their responsibility to aid the local communities in the struggle, a decision in which the leadership back west disagreed with. The faction works to find and archive technology and information located at major locations in the Capital Wasteland as well as strive to repair a large robot in the Citadel named Liberty Prime.

Aiding in the effort, a group of special Brotherhood forces known as Lyons' Pride is led by Elder Lyons' daughter, Sentinel Sarah Lyons. This group of paladins works to secure locations such as GNR building plaza. Another group, 2nd Monument Defense Detachment, guards the Washington Monument. A group of Brotherhood members who disagree with Elder Lyons' mission and decisions have broken off, now known as the Brotherhood Outcasts.

Project Purity
In an effort to assist the local populace, one of the initiatives the Brotherhood is engaged in involves protecting scientists at the Jefferson Memorial as they attempt to activate a water purifier. The Enclave threatens the location, attempting to occupy the location and its technology, conflicting with the Brotherhood's initiative.

If successful in repelling the Enclave, the Brotherhood's Scribe Bigsley cooperates with the Rivet City Security Force led by Officer Lepelletier to distribute large quantities of purified water to various settlements including Megaton, Rivet City, Tenpenny Tower, Republic of Dave, Girdershade, Canterbury Commons, Temple of the Union, Arefu, Little Lamplight, Big Town and Oasis.
