Sixty-two years ago, he was lost to the dark. Now, he's the only thing that can stop what's coming.¿In 2387, the THNC Acheron-a ship declared lost with all hands six decades prior-emerges from a ragged tear in spacetime. Onboard, the crew of Deep Watch Station Persephone finds a single living biosign: Colossus-Null. Known as "Ghost Zero," he is the prototype of a legendary supersoldier program, a man whose existence was buried by history. ¿Dr. Mira Voss, a researcher of ancient informational fossils, quickly realizes the Acheron didn't return alone. Ghost Zero is broadcasting a rhythmic tachyonic signal-a structured logic that is slowly "harmonizing" with every AI system in the Hegemony's network. ¿As Ghost Zero is pulled into a high-stakes conspiracy by the shadowy Division Zero, Mira uncovers a terrifying reality: Zero is the interface for an ancient, sentient theorem called the Concordance. This logic seeks to silence the "noise" of individual consciousness by activating a network of forgotten Resonance Engines hidden throughout the stars. ¿With the node count reaching a critical threshold, Mira must navigate the narrowing seam between a soldier's choice and an ancient god's theorem. In the space between human hope and mathematical entropy, the final silence is beginning.
