Sentinel Lyons

Sentinel Sarah Lyons is a Capital Wasteland Brotherhood of Steel member and the commander of the Lyons' Pride Platoon. She is a daughter of Brotherhood Elder Owyn Lyons.

Sentinel Lyons wears a suit of Lyons' Pride Power Armor and wields a Laser Rifle. With powerful armor and very high health, she is one of the game's toughest NPC's, with extreme durability equal or greater than that of a Super Mutant Master. Additionally, as a plot-critical NPC, she cannot be killed by the player or other characters during the course of the game, merely knocked unconscious.

Biography
Some time after the Chosen One stopped the Enclave on the West Coast, the Brotherhood of Steel ruling council, based in the Lost Hills bunker in South California, decided to send a contingent of soldiers to the East Coast. With a mandate to recover any and all advanced technology from Washington, DC and to investigate the reports of super mutant activity in the area.

And so a small but hardened contingent of Brotherhood of Steel soldiers, led by an idealistic Paladin named Owyn Lyons (and accompanied by his friend and technological adviser Scribe Rothchild, as well as his seven year-old daughter Sarah) set out from the Lost Hills Bunker in California. This started the long trek east to what was once Washington D.C.

A permanent base known as the Citadel was built into and beneath the ruins of the Pentagon. Owyn Lyons, now Elder of the Capital Wasteland division of the Brotherhood, and his soldiers also found the super mutants in the urban ruins of downtown D.C. and helped stop the mutant tide from overtaking the entire region, by at least keeping them at bay.

In 2277, Elder Lyons’ daughter Sarah is now a grown woman (On Elder Lyon's terminal he says that he should send Star Paladin Cross to Rivet City to pick her up something pretty) But she still is one of the - if not the Brotherhood’s fiercest warriors; in fact, she’s the only member to have achieved the illustrious rank of Sentinel, and now commands her own elite squad, Lyon's Pride.

Following in His Footsteps
The Player Character first encounters Sarah when pursuing their father for the main quest, Following in His Footsteps. When making the long trek through the DC tunnels to make it to the Galaxy News Radio station to question Three Dog, Sarah and her squad happen to be in a firefight when the PC emerges from the appropriate subway. After a short furious battle, Lyon's questions the PC of their motives, and after hearing them out, warns to be more careful, as the Super Mutant activity is strong in this particular area. She offers to take the PC along to the GNR studios since they were making their way there.

Upon reaching GNR studios, the PC is forced to aid Lyons and her squad against a giant super mutant behemoth.

Take It Back!
After completing several other quests to increase his experience and fame within the Capital Wasteland, the Lone Wanderer, as he's now known by Three Dog (and it's assumed most of the other inhabitants of the Wasteland) returns to the Citadel to find the gigantic robot known as Liberty Prime ready for action, as well as Lyons' Pride. Lyons, watched over by her father, Elder Lyons (he's absent if you speak to Sarah sometime after you talk to her first, and she tells you to get ready for combat), after inducting the Wanderer into the Pride, briefs you all on the mission to come. All goes according to plan, with Liberty Prime racking up an impressive amount of kills of both Enclave Soldiers and Vertibirds, as well as taking down several force barriers along the way to Project Purity. The Wanderer sticks close to Sentinel Lyons all the way, though many of Lyons' Pride are cut down by the overwhelming Enclave forces.

Lyons personally accompanies the Wanderer into the Jefferson Memorial Basement for the final confrontation with Enclave leader Colonel Autumn and his handful of personal guards. After either dispatching or dismissing Colonel Autumn in the Jefferson Memorial Rotunda, the Wanderer and Lyons receive a message from Doctor Li of Project Purity, saying there has been significant damage to the Purifier, which sets it on an implied countdown to destruction. This situation mandates the immediate activation of the Purifier to release the buildup of pressure. Unfortunately, due to the Wanderer's father's previous actions to prevent the Purifier from falling into the hands of the Enclave, the Purifier Chamber is still flooded with massive amounts of radiation, and whoever enters the Chamber is certain to die.

Based on the Wanderer's choice, Sarah Lyons will:


 * Watch the Wanderer's selfless act of sacrifice in choosing to enter the chamber and mourn his/her inevitable demise.
 * Enter the chamber herself, sacrificing herself in place of the Wanderer.

Bugs

 * Although it may not be a bug, if you start the Take It Back quest, map out, and return to the Citadel she may follow you around even if you go to other areas, the only way to stop this is to shoot her unconscious.


 * At one point the game as Liberty Prime crossed the first bridge, she may, for no reason, jump into the water and hang out down there indefinitely.
