About 800 years prior to Radiant Dawn, a great conflict arose between the Beorc and Laguz. In an attempt to stop the fighting Ashunera caused The Great Flood, a great deluge that killed all except those living in the highest peaks of Tellius. Lamenting for the destruction she caused, Ashunera, under the advice of Lehran, split herself into two beings. Her fission resulted in two separate beings of her original self. Yune, a child entity who would embody her emotions and Ashera who would embody order.
