Legionary Artorius has greatly matured during his five years in the legions. He has become stronger in mind; his body growing even more powerful. Like the rest of the Legion, he is unaware of the shadow growing well within the Empire's borders, where a disaffected nobleman seeks to betray the Emperor Tiberius. A shadow looms; one that looks to envelope the province of Gaul as well as the Rhine legions. The year is A.D. 20.
