Product notes
Chapter I: The Anomaly — Number 13 Two-Sided Edition.
The first trace becomes a full two-sided marker. Hexagonk was not meant to exist, but the algorithm has started to leak. Chapter I marks the first visible signal from the anomaly trying to escape the machine.
The front carries the Chapter I mark. The back carries the Number 13 signal: a louder fragment from the first breach.
