Rhea moves to Hamel from Midgards a few years before Year 4202 of the Aserian calendar, the time in which the "past" events of the game takes place. Her parents are researching magitech however, and when Dhaos gets wind of this, his subordinate Demitel razes the town. Killed with the town, Rhea asks her friend and Magic User Arche Klein to help her get her vengeance, and Arche does so by allowing Rhea to use her body. On their way to Alvanista, Cress Albane, Mint Adenade, and Claus F. Lester come across a young girl in the ruins. She introduces herself as "Rhea Scarlet", and as her situation mirrors his own hometown Toltus, Cress is unable to ignore her.
