Marius begins his story as a soldier having just successfully completed his training, who is about to leave Rome to serve his duty in the relatively sedate II Legion, holding a post in peaceful Alexandria. Just before his deployment, he enjoys a return to his family in Rome and the adulation of his father Leontius, a former general and current member of the Roman Senate. Marius' visit is cut short by a barbarian incursion; a running battle through the streets of Rome results in the death of his parents and younger sister. Commander Vitallion, a friend and former comrade of the slain Leontius, transfers Marius to his XIV Legion, and promises Marius vengeance for his murdered family. Vitallion leads the XIV Legion to Britain, but the fleet is ambushed off the coast; Marius leads the counter-attack, rallying the surviving Roman troops and nearly single-handedly preventing the destruction of the remainder of the fleet, which impresses Vitallion. Marius is promoted to Centurion.
