The Overseer…She was the heart of soul of Vault 76 for twenty five years. After Reclamation Day, she disappeared…leaving a trail of holotapes across Appalachia detailing her journey. 
Instead of dying on some lonely mountainside, she’s alive & wants to meet.
A live Overseer complicates the Colonel’s plans, but a dead one could become a martyr. Valeria must walk a fine line to discover what the Overseer intends, then decide how to proceed. Sometimes, new threats make for strange bedfellows.
