Lucy (Fallout)

Lucy is a psyker found in the Master's Lair in 2161.

Background
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. Presumably, she is one of the Master's failed experiments in trying to awaken psychic powers in humans, as Lucy is quite clearly insane.

Lucy is a telekinetic-dominant and a minor photo kinetic psyker. These powers are apparently suppressed when Lucy was fitted with a Psychic Nullifier.

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.
