Sierra Petrovita

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

Background
Sierra is an avid collector of Nuka-Cola merchandise and products and is enthusiastic about sharing information about her collection with those she encounters in her travels. She mentions that she has been the winner of the Nuka-Cola Fan Club Collection Award for the past ten years in a row, and currently serves as the President, the Recording Secretary and the Treasurer of the Nuka-Cola Fan Club.

Her collection is stored at her home in Girdershade, a settlement with two residents including Sierra and her neighbor, Ronald Laren. Ronald agreed to join Sierra's Nuka-Cola Fan Club and assists her in scouting for new items for the museum. He also fights off raiders who attempt to attack the settlement.

Around 2287, she achieved her dream of making it to the Nuka-World amusement park after having traveled hundreds of miles. Her goal is to finish a contest offered before the war, hoping that it will lead her to the original Nuka-Cola formula.

Daily schedule
In Fallout 3, Sierra stays in her house, drinking Nuka-Cola. In the Fallout 4 add-on Nuka-World, she can be found near Bradberton's office in Nuka-Town USA.

Quests

 * The Nuka-Cola Challenge: Sierra has her own Nuka-Cola museum which she gives tours. After completing the tour she will give the Lone Wanderer an ice cold Nuka-Cola and ask them to gather 30 Nuka-Cola Quantums for 40 bottle caps per bottle which adds up to 1200 caps. Completing the quest her way grants good Karma.

Bugs

 * If you kill Sierra and then steal items from her house, she may protest, even though she is dead.
 * If you fight any creatures outside of Sierra's house and then enter Sierra's house, you will not be able to communicate with her because she is fleeing. If you enter her house while enemies are still nearby, she will flee the house and disappear forever. Sometimes, she may run for cover at another house in Girdershade and can be found there, rather than fleeing town.
 * If you plant an explosive on Sierra and then ask her to make a Mississippi Quantum pie, she will start making it, but explode during the process. The player is stuck waiting for it to be made. Loading a previous save fixes this problem.
