"Ancient Adria, where the light of the sun shines; in that boundless land, the hymns of heroes are sung."
When the world began, chaos enveloped everything. God the Father used his supreme divine power to seal Chaos in another dimension. Afterwards, God the Father created the continent of Adria. It was an extremely beautiful paradise, a legendary world of swords and magic, where all life created by God the Father coexisted peacefully.
However, there is never eternal peace in this world.
Adria is in real trouble now.
Thus, a hero was born.
