Sierra's Nuka-Cola kingdom

Sierra Petrovita is a 26-year old[1] Nuka-Cola addict living in Girdershade in the year 2277. Sierra is blissfully and innocently unaware of her neighbor Ronald Laren's obsession with her or his unsavory intentions with her.



Sierra was born 2251[2].

Daily schedule

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

Interactions with the player character

She has her own Nuka-Cola "museum," (really just 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. Taking the tour initiates The Nuka-Cola Challenge quest in which the Lone Wanderer must gather 30 Nuka-Cola Quantums for 40 Bottle caps per bottle. Completing the quest her way grants the player good karma.

Should you instead help Ronald Laren in his quest to sleep with Sierra by giving him the Quantums (which he then gives to Sierra), she completely misunderstands his subsequent sexual innuendo and believes he intends to propose marriage to her. The player will receive 40 Bottle caps (but, if you succeed in a speech check you can get 80 Bottle caps) as well as bad karma.

After completing her mission to obtain a large supply of Nuka-Cola Quantum, if you bring her 1 Nuka-Cola Quantum, 1 bag of Flour and 1 bottle of Vodka, she can make you a Mississippi Quantum Pie.

  • The Pristine Vending Machine near her door is used for storing Nuka-Cola Quantums during and after the quest The Nuka-Cola Challenge. The key does not exist.
  • With the Quantum Chemist perk obtained, it is possible to steal most of the Nuka-Colas in Petrovita's home, converting them into Nuka-Cola Quantums, and handing them in to her instead. Whilst there is karma loss, it makes the quest shorter, and frees up more Quantums in the wasteland to be used as Nuka-Grenades.
  • Fawkes seems to attack her for no reason, provoked or not.
  • 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 your gone I'll whip up some of my Quantum Sorbet", which means she knows more than one recipe.

Behind the scenes

  • There are 65 Nuka-Colas in Sierra Petrovita's House (including on top of the Nuka-Cola Machine), 71 if you include the 5 Ice-Cold Nuka Colas in her fridge and the one she gives you at the end of her tour. This is far more than the runner-up location, the 19 Nuka-Colas in the jack-knifed truck with Old Olney's Nuka-Cola Quantum delivery.

Sierra Petrovita only appears in Fallout 3.


  • If you kill Sierra and then steal items from her house, she may protest, even though she is dead. (PC, 360)
  • 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. (PS3, 360)
  • 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 player is stuck waiting for it to be made, loading a previous save is needed. (PS3)
