In ancient times, the Light Family was known for forbidding their offspring from mixing their blood with those who carried other elements for many generations. This meant they were able to pass down the most potent element which is light in every generation of Lights.
Thus, because of their best effort, Lights have produced numerous healers and saints whose names have been recorded in the history books of Castella. Not only that, but the Lights also have been of great help in winning numerous wars in history which was mostly lined up by the warriors of Light and was led by the Archduke in every war they fought over.
