Rinea

Rinea is a noblewoman from an impoverished Rigelian house and is engaged to Berkut. Even within the Empire, she is renowned for her beauty, and the one person whom Berkut trusts without reserve. Rinea met Berkut at a royal ball. Despite the lesser nature of her noble house, Berkut was charmed by her beauty and offered to dance with her, thus beginning their romance.

During the events of Shadows of Valentia, Rinea is first introduced when Alm's forces storm Zofia Castle where Berkut was stationed. Rinea showed no interest in the battle as she detested violence. Berkut was content to sitting back and watching the battle unfold with her at his side.
