Sierra Petrovita

Sierra Petrovita is a Nuka-Cola obsessive who lives in Girdershade in 2277. Ten years later, she can be found at the Nuka-World amusement park near the Commonwealth.

Sierra is completely obsessed with Nuka-Cola and everything related to it. She is largely incapable of holding a conversation without trying to steer the subject towards the soft drink. She maintains a Nuka-Cola hoard-slash-museum in her home.

By 2287, her obsession led her to the derelict Nuka-World amusement park, after travelling hundreds of miles to acquire more artifacts for her collection. Her ultimate goal is to win an ancient, forgotten contest: find ten hidden Cappys in the park and meet Nuka-Cola inventor and CEO John-Caleb Bradberton in person. Though he must be long dead, what matters to Sierra is becoming the greatest Nuka fan in the world... and acquiring the original Nuka-Cola formula.
