Overseer (Fallout 76)

The Vault 76 overseer has already left the vault when the player starts a new game, though she does speak through the intercom to the player telling you to leave the vault. It is speculated that the Vault 76 overseer is a Robobrain (most likely Brainpower 4) as there are no human NPCs in Fallout 76.

Quest: First Contact
when the player leaves the vault 76 for the first time the player is tasked with the mission to find the Vault 76 Overseer in Flatwoods.
