Vault 101's second Overseer
Becoming Overseer in 2127, he led Vault 101 dwellers according to the same isolationist doctrine preached by his predecessor, but also attempted to garner as many senior vault dwellers to become complicit in the vault experiments. In addition, the second Vault 101 Overseer was the first Overseer able to communicate with, and even visit, the outside world by using the secret tunnel in the Overseer's office. However, for all other intents and purposes, the vault dwellers were sealed in with the motto "we are born in the vault, we live in the vault, and we die in the vault".
Vault 101's second Overseer does not appear in any game and is only mentioned in the Prima Official Guide for Fallout 3.
