The Source Rings encircle the world. Humanity is both trapped inside them like beasts in a cage and the wielder of the world's fundamental power. When the Wheel of Fate is shattered and Ringforce falls to zero, all that remains is a breathing vessel, waiting to be filled by something or have something taken from it.
At Grinsport, eight lighthouses guard eight layers of locks, and their ever-burning living flames are the harbor's only light. On the eve of the Blood Tide, delegations from all sides arrive in Grinsport, each with their own agenda, unaware that the eight lighthouses are being woven into a noose of fate. Someone is secretly collecting Ring Pact samples from every faction, preparing to shatter enough Wheels of Fate at the same time and place.
Lin Jiugai is merely an experimental subject who fled to the harbor. Eight cracks already mark his Wheel of Fate, and its end could come at any moment. The only thing he can do is ask the question everyone is avoiding before everything ends:
Who catalogued these eight Source Rings?
