With the Parthians once again defeated and the Antonine plague sweeping through the empire, Marcus Aurelius must defend Rome from yet another opportunistic enemy – the tribes to the north, or as Rome called them, the barbarians. The northern borders were under threat from a rough coalition chiefly lead by the Marcomanni, and Marcus heads out to take control of the Roman forces himself. It is a conflict that will dominate his time for the rest of his life.
