A thousand years ago, there were two powerful forces on this land. One was the Balus Bulku Empire, guarded by the god of "Raphael's Pupil", and the other was the Lagus Kingdom, guarded by the god of "Mikal's Pupil".
Ten years ago, the guardian god of the Lagus Kingdom, "Philoene", was still in slumber, and thus unable to protect the kingdom when the war caused by the "Pandora's Box" broke out, leading to the destruction of the Lagus Kingdom.
