Amongst the sprawling hives of Terra, Amon Tauromachian of the Emperor's Custodians plays a deadly game as he investigates rumours of treason on humanity's home world. Amon Tauromachian, one of the Emperor’s elite Custodian Guard, returns to the Imperial Palace after a year on one of the Blood Games by which these exalted heroes train. Tasked with a new mission, he is sent to the hives of Hy Brasil to check on the loyalty of a notorious troublemaker. With the galaxy at war and half the Imperium’s armies in rebellion, any hint of heresy on the Throneworld must be stamped out. Amon’s mission draws him into a web of deceit and betrayal, where no one can be trusted and nothing is at it seems. Can he unravel the truth and secure Terra for the Emperor? It's an in-depth look at Terra itself, and how treachery lurked at the Imperium's heart even as the Heresy began. There's also a fantastic, action-packed look at what the Custodians do when they're not out fighting. Running time 1 hour and 27 minutes. Read by Jonathan Keeble
