Stella grew up in New Reno. After she left, she spent most of her life as the sheriff of Caliente protecting it from the 80s, White Legs, and sometimes even the locals. She eventually got tired of being a sheriff and took up a job as a caravan guard.
Arrival at Zion: Stella is among the group of caravaneers who travels to Zion along with the Courier. She is killed along with the others during the White Legs' ambush shortly after. Like the other members of the caravan, her death is scripted, and thus inevitable.
