"A century ago, the sky tore open, and the mountains fell."
In a world crushed beneath the feet of dormant, mountain-sized Crystal Titans, humanity clings to existence inside the oppressive, steam-choked walls of the Cogwork Alliance. The air is poisoned with toxic crystal dust, and the only magic left—Resonance—is a lethal, radioactive force that consumes the soul just as quickly as it grants power.
Corvin is a "Silencer," an elite, ruthless assassin tasked with hunting down those corrupted by the dust. But beneath his cold exterior lies a deadly, heretical secret: he possesses the very forbidden magic he is sworn to eradicate. One slip, one wrong move, and the religious zealots of the Alliance will burn him at the stake.
His grim existence violently shatters when he crosses paths with Kael, a desperate young scavenger who shouldn't exist. When Kael touches the lethal Titan crystals, they don't turn his blood to stone. Instead, they sing to him, glowing with a miraculous, obedient light.
Now, Corvin has made the ultimate mistake: he spared the anomaly.
Branded as heretics and hunted relentlessly by the Alliance’s fanatical Purifiers, the deadly assassin and the miracle boy are forced to flee into the "Gaps"—uncharted, nightmare-infested wastelands prowled by living crystal mutations. But as they fight to survive and uncover the horrifying truth behind the Titans, they realize the end of the world was never a divine punishment...
It was a desperate, cosmic scream for help.
Bound by a shattered world and chased by an army of zealots, they must become the saviors of the very monsters that destroyed humanity. Will they decipher the melody of destruction before it consumes the last remnants of their souls, or will the Titans finally awaken to finish what they started?
