Ashe and Rasler appear in backstory of the Return to Ivalice arc. They are twins who were killed in the Garlean invasion 30 years ago. Before dying, Rasler entrusted his sister's safety to Ba'Gamnan, a fusileer in the Dalmascan Army, and entrusted him with an auracite necklace as well. The princess perished before they could escape the Garamsythe Waterway, wishing in her dying breath for Ba'Gamnan and his companion to survive.
Years later, The Warrior of Light hears of rumors of someone claiming to be the princess leading a rebellion. Given her confirmed death and the large time gap, the rumors are written off as false, and the woman is never seen, instead having Fran meet with the Warrior.
