Angela Callahan was a librarian who resided in Vault 51.
Background[]
In May 2078, she started worshipping the vault's ZAX artifical intelligence, writing daily prayers to it in her terminal.[1] Given that Reuben Gill became overseer by virtue of being the last surviving resident of the vault, it can be assumed that she was killed in the fighting.
Appearances[]
Angela Callahan is mentioned only in Fallout 76, introduced in the Nuclear Winter update.
