Kane, a Celtic prince whose kingdom fell to Rome, is enslaved as a gladiator. After seven brutal years, he escapes the arena and is rescued by Livia, a small-town physician. When bandit chiefs Gracchus and Drusus threaten the town, Kane leads the defense with his lethal combat skills—defeating them, recruiting the fierce warrior Varro, and seizing a salt mine. He transforms from a fugitive who only wants to survive into a guardian of peace. This is a story of chains and freedom, violence and order—he broke his own shackles, yet chose to bear the weight of responsibility for others.
