Relva was born of the bond between human and swan. Her residence was not a town, but an idyllic forest lake. She cherished the peaceful days living with her dear friends, but they were not to last. Tragedy struck when orcs attacked and polluted the lake, and Relva was the only one able to escape with her life. Swearing revenge, she enrolled in the nearby town's knight academy to gain the necessary strength to levy retribution. However, with her change of home and acquisition of new allies, her desire for vengeance gradually dwindled.
