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.
