Lucy is one of the four psykers, along with Gideon, Wiggum, and Moore that are kept behind a force field in the Master's lair beneath the Cathedral. She is one of the Master's failed experiments in trying to awaken psychic powers in humans, as Lucy is quite clearly insane.
Interactions with the player character
- She proves to be quite unintelligible when the Vault Dweller encounters her. It can be assumed that Lucy dies with the destruction of the Cathedral.
Lucy only appears in the original Fallout.
