Background Edit

Sierra was born in 2251. In 2277, she is a fair-haired 26 year old woman who shows little regard for matters outside consuming and hoarding Nuka-Cola and collecting merchandise relating to it, much to the dismay of her neighbor Ronald Laren, who remains in Girdershade in the hope of seducing her. 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]

In the Fallout 4 add-on Nuka-World, ten years later, she has traveled to an amusement park west of Boston, Nuka-World, in hopes of recovering the Nuka-Cola formula for her collection.

Daily schedule Edit

In Fallout 3, 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.

In the Fallout 4 add-on Nuka-World, she can be found near Bradberton's office in Nuka-Town USA.

The Nuka-Cola Challenge: Sierra has her own Nuka-Cola "museum" (a display of her collection within her shack) which she gives tours in.

Notes Edit

She is the only non-player character known to be addicted to Nuka-Cola Quantum.

When asked about 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 the Lone Wanderer off to get the 30 Quantums, she may say, "Hurry back, maybe I'll make some of my legendary Quantum Sorbet!" implying she knows more than one recipe.

She can reveal the location of Evergreen Mills through dialogue if asked if there is anything else interesting in the area (she warns the Lone Wanderer 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.

In Fallout Shelter , it is possible to find an NPC with a randomly generated appearance bearing Sierra's name in random encounters in the wasteland.

In the Fallout 4 add-on Nuka-World , fulfilling John-Caleb Bradberton's request of letting him die at the end of the Cappy in a Haystack quest, after accepting Sierra's request to not kill him, will result in Sierra insulting the Sole Survivor before turning hostile, not only due to killing her idol, but also for lying to her, just to get her prized possession, the Nuka-World jumpsuit. Players intent on securing both the powerful Nuka-nuke launcher and her jumpsuit can either kill her, leave the area quickly after she becomes hostile, or use console commands to no-clip through the door.
