She was chosen to be the Sun Queen'

She was chosen to be the Sun Queen's successor. However, Hoshi had discovered what the ceremony would do to her. She found that the ritual would make her disappear, while replacing her body with the Sun Queen's soul. So, believing she would act for the sake of Yamatai and all the priestesses that would follow her, she took her own life with a dagger stolen from the Stormguard General.
