In fact, he told me he's going to "butter my muffin". Isn't that sweet that he'd do such a silly little chore for me? Now all I need are muffins...

Sierra Petrovita is a Nuka-Cola addict living in Girdershade in the year 2277.


Sierra was born in 2251. She is a fair-haired 26 year old woman who shows little regard for matters outside consuming and hoarding Nuka-Cola, much to the dismay of Ronald Laren. Her fanaticism for the drink is without question, as she subsists solely on it. She has spent every bottle cap her parents left her acquiring the drink from merchants, travelers, and towns spread throughout the Capital Wasteland.[1]

Daily scheduleEdit

Sierra stays in her house all day drinking Nuka-Cola and doing other miscellaneous things. In addition, she hounds passing travelers for any trace of Nuka-Cola Quantum.

  • The Nuka-Cola Challenge: Sierra has her own Nuka-Cola "museum" (a display of her collection within her shack) which she gives tours in. After completing the tour she will give you an ice cold Nuka-Cola and ask you to gather 30 Nuka-Cola Quantum's for 40 bottle caps per bottle which adds up to 1200 caps. Completing the quest her way grants the player good Karma.
  • Mississippi Quantum Pie: After completing "The Nuka-Cola Challenge", she can make you a Mississippi Quantum pie out of 1 Nuka-Cola Quantum, 1 bag of flour and 1 bottle of vodka.

  • She is the only non-player character known to be addicted to Nuka-Cola Quantum.
  • When you ask her what kind of recipes she can make with Nuka-Cola Quantum, she says it's so rare, she only knows one. However, when she sends you off to get the 30 Quantums, she may say "Maybe while you're gone, I'll whip up some of my Quantum Sorbet," implying she knows more than one recipe.
  • She can reveal the location of Evergreen Mills through dialogue if you ask her if there is anything else interesting in the area (she warns you to stay away from it).
  • If told about Ronald Laren's sexual intentions for her, she will play it off as a joke on her.

  • pcIcon pc ps3Icon ps3 xbox360Icon xbox360 If you kill Sierra and then steal items from her house, she may protest, even though she is dead. [verified]
  • pcIcon pc ps3Icon ps3 xbox360Icon xbox360 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. [verified]
  • ps3Icon ps3 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. [verified]
