Sara has finally confronted the truth: the artifact isn’t Zorathian, isn’t understood, and definitely isn’t under anyone’s control. It chooses its hosts… and it remembers them.

High Command has been hiding the real stakes, the real history, and the real danger — and Castor Ames is now at the center of a test older than any empire.

The Krenn has the Book. Castor still feels it pulling at him. And Sara is racing toward a choice she may not be ready to make.

In this episode Castor and Sara continue to learn about each other. But does Vra'shek have the strength to rip the artifact away from Castor?

Sara Sudis detects renewed Krenn activity near the university district. The creature’s thermal inversion signature confirms her worst fear: he’s adapting.

Meanwhile, Castor Ames pieces together centuries of encounters with the “Book of Fire” — from medieval Italy to ancient Anatolia to WWII battlefields. Each account bears the same fingerprint, suggesting the artifact’s presence across time.

The resonance between Sara and Castor reaches critical levels. A kiss. A surge of energy. Proof that emotion may amplify the artifact’s dimensional field.

But field recordings end abruptly with civilian casualties in an alley downtown. The Krenn has begun hunting again.
