From The Vault
||The following is based on Van Buren and has not been confirmed by canon sources.
General Andrea Brixley is the commander of the Brotherhood of Steel's Maxson Bunker in 2253.
Andrea began her career in the Brotherhood as a scout/explorer. She was originally sent east to confirm the existence of Maxson Bunker and to use it as a staging area for her explorations. She was accompanied by a team of four paladins.
After the war broke out between the BOS and the NCR, Andrea was promoted to commander and placed in charge of the bunker. She also received the title of Elder Paladin, as did her four companions. Andrea is not comfortable with leadership and would prefer to spend her time exploring. She isn't very organized and is content to let people do what they are best at with little supervision. Fortunately, her supporting staff recognizes her flaws and cover for her.
Andrea's most ardent supporter is her best friend and fellow paladin, Glenn Deering.
Andrea Brixley was to appear only in Van Buren, the cancelled Fallout 3 project by Black Isle.
Behind the scenes
The Maxson Bunker design document contains two contradictory statements about Brixley - they do not agree on whether she was promoted to Elder/General before or after the war with the NCR broke out.
