What remains of a man once the only thing anchoring him is no longer what he protects, but what he remembers feeling while destroying?

In the bone-built alleys of Dis, twelve attackers emerge from the corridors hunting for the one thing the system still hasn't managed to extract: an Attuned child, one more Recordante for the market. The Anomal — Case 72-T, ENR, the anomaly the system was never built to reflect — confronts the choice he's been deferring since the first uncontrolled break: contain what he carries, or release it with intent. Not for the child. For the relief he tasted once and now wants again.

Chapter 17 closes Volume I with the scene that names the threshold crossed:

— Killing stops being reaction and becomes deliberate choice.
— The Unborn manifests for the first time as presence rather than rumor: a bodiless echo that already knows how this story ends.
— The cost of release gets fixed in place: what accumulates isn't guilt, it's forgetting. Each time the Tic Tac falls silent to permit destruction, something disappears and doesn't come back.
— Gula offers the way out, toward "where those who can no longer return go," and the Anomal takes it knowing there's no path back to who he was before the alley.

The question the first attacker asked without expecting an answer — how do you live with this — finally gets one, and it isn't the answer readers expect. You don't live. You survive: one relief after another, one loss after another, until carrying what little remains — a crooked drawing, a child's parting wave — is the only thing separating a man from becoming what hunts him.

This chapter closes the founding arc of The Threshold and opens the door to Volume II: The Shadow, where the weapon will learn to aim.
