Clarke and I joined the Brotherhood around the same time. He's been my closest friend for years. But since the battle, I feel like I'm losing him.— Knight Lucia

Knight Lucia is a Brotherhood soldier at the Boston Airport. She is part of the Brotherhood's logistics division in 2287.


Lucia works in the supply depot at the Boston Airport under Knight Sergeant Gavil. She expresses pride after her first combat experience followed the Prydwen's arrival, though she worries how the event has affected her friend D. Clarke.[1]

During the quest Duty or Dishonor, Lucia shows concern for her friend's condition and the suspicion that D. Clarke is involved in the theft. [2] Depending on the outcome Lucia supports the decision.[3] If the Sole Survivor sides with the Brotherhood of Steel during the mission Ad Victoriam, Lucia will escort Liberty Prime to The Institute.

  1. Knight Lucia: "The battle for the airport. It was our first real combat mission. It was something to see. The Prydwen coming in under full Vertibird escort, guns blazing. It was everything I had hoped for. But Clarke... he hasn't been the same since. It's like he's just given up."
    (Knight Lucia's dialogue)
  2. Knight Lucia: "The battle... it changed him somehow. Since then, I've noticed him slipping off by himself, once or twice a day. I never thought much of it, but..."
    (Knight Lucia's dialogue)
  3. Knight Lucia: "I heard about Clarke. It's been a little hard for me to take. But... thank you for finding the truth. It had to be done."
