|First appearance||Dragon Harper|
Early in the Third Pass, before Jassi Impressed Falth, she treated dragons and their riders at Ista Weyr after Threadfall. After impressing Falth, Jassi was one of the young queen riders who went to Eastern Weyr, "so my Falth could grow and help with the next Threadfall.” When B'carran's dragon Mayorth was injured by a Mrreow, Jassi was chosen to treat him.
After it was decided to form impromptu queens' wings among the weyrs while Kindan was gone, Jassi was chosen to take a turn as a Weyrlingmaster.
Fiona was very pleased with the outcome of the mating flight that paired Jassi with J'lian. He was no youngster, but after the devastating losses in the Istan leadership, he was the obvious future leader of Ista Weyr; and, his Neruth’s mating with Jassi’s Falth meant that, on her return to Ista, he would become the true Weyrleader, just as she would inherit the senior Weyrwoman role vacated by Dalia.
