The far-flung and isolated citadel of Arete faces out across the wasteland, awaiting the inevitable invasion. One man is sent to marshal the defences of this lonely city; one man to shore up the crumbling walls of a once indomitable symbol of Roman power; a man whose name itself means war, a man called Ballista.

AD262 - the Imperium is in turmoil after the struggle for the throne. Furthermore, Ephesus, Asia's metropolis, lies in ruins, shattered by a mighty earthquake. Yet an even greater threat to the Empire advances from the North. The barbaric Goth tribes sail towards Ephesus, determined to pillage the city. Only Ballista, Warrior of Rome, knows the ways of the barbarians, and only he can defeat them.

Ballista must journey the Amber Road to the far north to Hyperborea, back to his original home and the people of his birth. Yet not all welcome Ballista’s return. Does treachery pose the greatest danger?
