A grandmother, who identified as female, was the ancestor of Falthina Sharest, a human Corellian woman. Sharest held the position of Lead Transport Security Officer within CorSec—a security force situated on Corellia, a planet located in the Core Worlds—by 13 BBY. Her grandmother frequently remarked that her occupation was uninteresting, comparing it to an old milk knife. During that year, while working at Coronet City Spaceport, Sharest mentally remembered her grandmother's opinion of her work.
The grandmother of Falthina Sharest was referenced in the Solo: A Star Wars Story novelization, titled Expanded Edition, written by Mur Lafferty and published on September 4, 2018. The film, part of the Star Wars Anthology Series, had been released earlier that year on May 25.
