Arthur Maxson

Elder Arthur Maxson is the last descendant of Roger Maxson in the year 2287. Maxson and his ancestors are the founders and traditional leaders of the Brotherhood of Steel.

Fallout 3
Arthur was born in 2267 and is a descendant of the legendary Roger Maxson, founder of the Brotherhood of Steel. His father, a high-ranking Paladin serving just outside the New California Republic, was killed in battle, and his mother, Jessica Maxson, sent the boy east to be raised under the tutelage of the respected Elder Lyons. Arthur tended toward timidity, which was the main reason his mother sent him to the Citadel.

From his computer (which the Lone Wanderer can hack without Karma penalties), the Lone Wanderer can discover that young Arthur enjoys writing stories, has a crush on Sarah Lyons (because she taught him to kill a man by stabbing him in the kidneys), and that there is a Guns and Bullets magazine underneath a bed in the den.

Fallout 4
After the events of Fallout 3 the East Coast Brotherhood of Steel faced a leadership crisis after Elder Owyn Lyons died of natural causes and his daughter Sarah Lyons was killed in combat shortly afterwards. The East Coast Brotherhood repeatedly appointed and deposed several ineffectual Elders until Arthur Maxson was appointed Elder of the East Coast Brotherhood by the West Coast Elders in 2283 at the age of 16, the youngest in the history of the Brotherhood, after displaying exceptional skill as a capable warrior and diplomat by defeating the supermutant leader Shepherd and brokering peace with the Brotherhood Outcasts, bringing them back into the fold.

Arthur returns in Fallout 4 as a twenty-year-old, fully trained and the leader of the Brotherhood in the East Coast and is torn between the ways of his predecessor: Elder Lyons, using technology to help others or the traditional Brotherhood approach by seizing any advanced technology they can as his chapter prepares to go to war with the Institute.

A charismatic leader and a skilled tactician, Arthur has won the respect and admiration of his men through his numerous exploits. He owes his scar to a fight that he led alone against a deathclaw at the age of 14, an opponent that even BoS veterans advise not to face single-handedly.

Fallout 3
He can usually be found in the Citadel B ring, where his room (and personal terminal) is located.

Fallout 4
Maxson, along with The Prydwen, will show up in the Commonwealth once the quest Reunions is completed. He can usually be found in the Main Command Deck of The Prydwen, and may also go to his room.

He will join the Brotherhood attack on the Institute during the quest Ad Victoriam, and become a temporary follower in The Nuclear Option.
