Reid Underwood

 was one of the members of Quaere Verum, a pre-war organization dedicated to exposing the vast conspiracy later known as the Enclave.

About
Reid was the last surviving member of Quaere Verum, and knew that he was the next to be assassinated so he hid the stolen item before he was found. Reid's mission could have been successful as the item was stolen 14 years before the bombs fell. The item was hidden in the desert, but the safe was abducted into the space ship after this. The locked safe is located in the Cargo Hold of Mothership Zeta. To access the safe, You must search for Reid Underwood's Computer (Hard) near the Vault section. The safe is located in the Junkpile near the Trash Compressor. The contents of the safe include Energy Cells (amount may vary taking account to the scrounger perk.) MPLX "Novasurge" Prototype Plasma Pistol note which is a journal taken down about the gun, and the MPLX Novasurge which was the first plasma pistol ever made.

Mentions
is mentioned in the Fallout 3 add-on Mothership Zeta.
