Vera Keyes

Warning: Spoilers ahead!

Vera Keyes was a starlet before the Great War and was also one of the celebrity notables invited to the Grand Opening of the Sierra Madre Casino. She was inside her suite at the Sierra Madre when the nuclear bombs fell across the US, which caused the casino's security system to engage and hermetically seal off the hotel. Unable to escape, Vera chose the only way out left to her, and overdosed on Med-X obtained from the Auto-Doc Mk.1 found in her bedroom. Her voice is needed to allow access to the vault found underneath the casino, which was a feature deliberately programmed into the hotel by it's builder Mr. Sinclair, who was in love with her. This depth of feeling is also indicated by the number of Starlet Holograms that are to be found in the Sierra Madre(both at the Fountain and in the rooms) which are all in the likeness of Vera Keyes.
