Lucia's personal key


  • Lucia, along with Gavil, is one of the very few named Brotherhood of Steel members to survive the destruction of the Prydwen during Airship Down, Rockets' Red Glare or With Our Powers Combined. She can be found at her usual workplace at the supply depot and will, of course, be hostile to the Sole Survivor.
  • Lucia will assist the sole survivor in escorting Liberty Prime to the Institute.
  • Lucia and D. Clarke have beds next to each other on the Prydwen's barracks section. In their lockers are notes they have written to each other that shed some light onto D. Clarke's unusual behavior.


Knight Lucia appears only in Fallout 4.
