One of the twelve Valkyries of Freya. She is first seen attempting to hunt down Fenris Fenrir, although the warlock escapes. She then devastates Fayon with an army of Giants. Sara is, in fact, the half-sister of Iris. For some horrible, unknown reason, Sara's (and Iris's) father killed Sara's mother and tried to kill Sara as well. Sara fled the village of Fayon and became consumed with a thirst for vengeance. She met and killed her father during the attack on Fayon, earning Iris's hatred. Curiously, she saves both Iris and Fenrir from the witch Bijou, though she dispassionately tells her half-sister that she will finish Iris the next time they meet. She wields the legendary Sword of Retribution, Haeryongdo.
