Ashunera is the creator goddess who created life on Tellius. The Zunanma, the ancestors of the Beoric and the Laguz admired and loved her; this love for the goddess led both to calling her the "Goddess of Dawn" in reference to her dawn colored hair. When her descendants went to war, Ashunera tried to stop them; but lost control of her emotions and accidentally flooded all but one of the continents in the world. In order to prevent another flood from occurring, the goddess decided to discard her emotions in which they manifested themselves as Yune, the Goddess of Chaos and Transformation and Ashera, the Goddess of Order and restriction.
During the events of Radiant Dawn, both of her halves were eventually reunited into forming the original goddess their true forms with the help of Ike and his army. After the events of Radiant Dawn and 1200 years later, she finally returns to Tellius once more and watches over it once more as its creator.
