Sentinel Lyons

Sentinel Sarah Lyons is a Capital Wasteland Brotherhood of Steel member and the commander of the Lyons' Pride in 2277. She is the daughter of Brotherhood Elder Owyn Lyons.

Background
Sarah Lyons was born in 2247 in the Brotherhood of Steel's Lost Hills bunker in California.

Some time after the Chosen One stopped the Enclave on the West Coast, the Brotherhood of Steel ruling council decided to send a contingent of soldiers to the East Coast with a mandate to recover any and all advanced technology from Washington D.C. 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 eight-year-old daughter Sarah, as well as his friend and technological adviser Scribe Rothchild) 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, but she is still one of the Brotherhood’s fiercest warriors, if not the fiercest. In fact, she’s the only member to have achieved the illustrious rank of Sentinel, and now commands her own elite squad, Lyons' Pride.

Relationships
She is the daughter of Elder Owyn Lyons. She also has taught Squire Maxson to shoot, and kill a man by stabbing him in his kidneys, as read on his terminal. Squire Maxson apparently developed a crush on her afterwards.

Daily schedule
During Following in His Footsteps, she can be found at the Galaxy News Radio building. After The Waters of Life she can be found inside the Citadel (up until Take it Back!). After the reactivation of the purifier and during much of Broken Steel, she's comatose in the Citadel infirmary if she survived the purifier attack. After the completion of Broken Steel, she can be found patrolling the Citadel (again, if she survived).

Interactions overview
* If you decide to destroy the Citadel she will turn hostile towards you and she will no longer be an essential.

Quests
The Lone Wanderer first encounters Sarah when pursuing their father for the main quest, Following in His Footsteps. After the long trek through the DC tunnels to make it to the Galaxy News Radio station in order to question Three Dog, Sarah and her squad happen to be in a firefight. This occurs just as the PC emerges from the appropriate subway. After a short, furious battle, Sarah questions the PC of their motives, and, after hearing them out, warns to be more careful, as the Super mutant activity is strong in that particular area. She then 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 Super Mutant Behemoth.

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. Here they find the gigantic robot known as Liberty Prime ready for action, as well as Lyons' Pride. Sarah, 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.

Sarah personally accompanies the Wanderer into the Jefferson Memorial Rotunda for the final confrontation with the Enclave's second in command 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 (unless Broken Steel is installed).
 * Enter the chamber herself, sacrificing herself in place of the Wanderer.
 * Wait until the Purifier explodes.

Effects of player actions
After Broken Steel she reacts to the player differently. If you destroy the Enclave mobile platform she will compliment you, but if you destroy the Citadel, she will turn hostile.

Broken Steel
 * If the player activates the purifier himself/herself, or uses Fawkes, Sergeant RL-3, or Charon to start it; it is revealed that an energy spike knocked both of you out. Two weeks later after you wake up, she's still in a coma, "unresponsive but stable". After the player escapes from the mobile base in Who Dares Wins, Sarah Lyons will appear again and pick you up in a Vertibird, taking you back to the Citadel. Afterwards, she can be found wandering around the Citadel. She is paler than her previous appearance, which some believe may have to do with the radiation.
 * If Lyons activates the purifier, she was killed by the radiation and doesn't appear.
 * If you betray the Brotherhood and launch the orbital strike on the Citadel instead, she and the other Brotherhood members who picked you up will attack you in a fury, calling you a traitor. It is possible then to kill her, as she will no longer be an essential NPC.
 * At the end of Broken Steel (if you chose the Good Karma path) you can talk to Sarah Lyons after the speech and depending on what you say, she may hint at possibly having a more personal relationship with you "if things were different".

Appearances
appears only in Fallout 3.

Bugs

 * At the end of the game Sarah Lyons can glitch into either saying that the control room still isn't clear or repeat the phrase "Steel be with you!"
 * After Waters of Life, before talking to Rothchild for the quest Finding the Garden of Eden, Lyons appeared on the road leading from Arlington Library to the Flooded Metro, walked along the road to a point past the Nuka-Cola Plant. Not sure if this will affect Take it Back!, had not spoken to her after entering the Citadel.
 * At the beginning of Take it Back!, as Liberty Prime crosses the first bridge, she may jump into the water and stay down there indefinitely.
 * At any point in the game, Lyons may talk about the Enclave fortifying the water purifier, and about the Enclave having Vertibirds. This happens only in NPC to NPC conversations though.
 * If you begin the Take it Back! mission, then fast travel to Falls Church, Sarah Lyons may appear as a follower in the area.
