Normally, I'd see Sara most likely pass during combat in hopefully a rather heroic way to where she's protected those she cares for and allows them to live, as Sara lives for heroics and helping others.
Buuuuut, to get away from just killing her off, whenever Sara would finally lay down her sword for good, she'd most likely focus on learning to write and read as best as possible, and then would start to write fiction novels. Heroic, clichè, cheesy fiction with the protagonist managing to always come on top and save most likely the world with their allies. She'd of course, exaggerate her own past conflicts to write in these stories, but I think it'd be nice for her to be able to just enjoy a peaceful life and living her heroics through her writing for when she's unable to still fight. Probably living alone, but close to her pretend sister. She'd be happy nonetheless.
