More Than a Legion (слэш)

When the Roman legions conquer his homeland, Dacian aristocrat Bucky Barnes is captured and enslaved. Back in the capital, he meets his new master, Roman Patrician Tony Stark, who recognizes the talent and authority his new slave possesses. In order to break him, Tony wills Bucky into the gladiatorial pool, but that strategy quickly backfires. Not only does Bucky win repeatedly by besting the finest fighters Rome has to offer, but he does so with a power and grace that leaves Tony breathless. When war breaks out in the Roman territories, Tony presses Bucky into helping train his soldiers. As they ride into battle together, trust and longing develop between slave and master in a way Bucky cannot imagine.
