"In the outskirts of space, and the far corners of the Polity, complex dealings are in play. Several forces continue to pursue the deadly and enigmatic Penny Royal, none more dangerous than the Brockle, a psychopathic forensics AI and criminal who has escaped the Polity's confinements and is upgrading itself in anticipation of a deadly showdown, becoming ever more powerful and intelligent. Aboard Factory Station Room 101, the behemoth war factory that birthed Penny Royal, groups of humans, alien prador, and AI war drones grapple for control.
