Meanwhile, Centurions Cato and Macro are living in Rome, awaiting reassignment to the legions after being compelled to quit the army invading Britain.

Due to the suspicious conspiratorial nature of the events surrounding the death of their previous commander, Centurion Maximius, both their lives are forfeit should they refuse.

During Cato and Macro's trip to Ravenna, they rescue a Greek merchant, Anobarbus, being tortured by brigands in the hills.

Upon their arrival, it is revealed Narcissus has placed Tribune - now Prefect - Vitellius in command of the operation, souring relations with the two centurions.

Macro and Cato strike up a friendship with Centurion Minicius, an aging auxiliary veteran who acquaints them with life at sea.
