Sarah hails from the planet of Roak, where her people are dubbed as the Featherfolk, human-like beings endowed with wings on their back. However, unlike the rest of her people who could fly for short periods of time, Sarah is unable to do the same, due to an unknown reason. Sarah grew up in virtual isolation, never even setting foot outside her village until she was assigned as an envoy to the kingdom of Astral. The Featherfolk are revered as sacred, but Sarah's isolation has left her so ignorant of the outside world that even her own people constantly worry about her. Her simple, almost naive kindness is completely guileless. She has the same surname as Erys and Ioshua from the first Star Ocean; the in-game dictionary mentions that she is not their mother, but more than likely their aunt through one of her younger brothers.
