Paladin Tristan

Paladin Tristan is a member of the Brotherhood of Steel in 2277.

Quests

 * Death From Above: Tristan is coordinating an assault on the Enclave Satellite relay station to scrounge for intel on the Enclave's next move.
 * Shock Value: Tristan sends the Lone Wanderer on a search for an odd component so the scribes can develop a special weapon.
 * Who Dares Wins: Tristan orders one to access Adams Air Force Base via the Presidential metro. After infiltrating it, he gives them further orders on their assignment.
 * Blood Brotherhood: Following the destruction of Adams Air Force Base, Tristan asks the player character to collect super mutant blood samples, so the scribes can research and develop a weapon that can destroy the super mutant population once and for all.

Effects of player's actions
He is the acting field commander of the Brotherhood forces in light of Sarah Lyons being unable to fight after the events at the purifier, and is in charge of all Brotherhood operations involving the Lone Wanderer and Liberty Prime, the first mission in the main Broken Steel questline.

Appearances
Paladin Tristan appears only in the Fallout 3 add-on Broken Steel.

Bugs

 * When you first encounter him in the Rockland car tunnel, he will sometimes be unarmed and in the "fist-fight" stance. Pickpocketing will reveal that he is carrying a plasma rifle and simply has no ammunition. He will find some ammunition by himself after Liberty Prime kills the first Enclave soldiers, but you can also reverse-pickpocket him some microfusion cells while in the tunnel which will make him fully operational after loading the next screen.
 * If Tristan suffers a crippled leg during the assault on the communications station, he will spend the rest of the game crippled never bothering to heal it.
