The people of the Riana federation have been trapped under a barrier that limits their magical abilities and threatens their existence unless they abide by imposed faith known as "harmony". But scriptures speak of a way to bring down the barrier when a mage who can master seven spirit gems appears.

Heron has set a goal to be that mage. So, with his adventuring partners May and Icarus, they set off to explore the lands of the Riana federation. In their journey, they'll discover that the state of the union is all but harmonious with political conflicts between its member states, rebellious cults, and prophets inciting chaos.

Will they manage to gather spirit gems? Why has no one so far managed to collect them? And how reliable are the scriptures that speak of salvation? Join in on the epic journey as our protagonists explore the mysteries of Riana federation and witness an adventuring party's heroic efforts to push themselves beyond their limits.
