The eastern provinces burn, and few dare to save them.

Suffering invasions, riots, and hunger, the decaying Roman Empire staggers against its most ancient enemy—Persia. Undefeated in over a century, the Shahanshah’s vast armies cross the Tigris, hungry to reclaim lands that once had been the jewel of their heritage. Driving Persia’s invasion are the vaunted Immortals, an elite band of Persian warriors unmatched in prowess.

Set against the invading forces are the undermanned and ill-equipped forces of Flavius Belisarius. Reeling from a pyrrhic triumph in Tauris, the Roman armies draw upon barbarian tribes and untested recruits to defend the Empire’s rich Mesopotamian provinces. Ordered to join them is Varus, a young Herulian freedman with little more than broken armor, an oathbound servant, and a mysterious connection to the Imperial Palace.

Though defeat is inevitable, the Emperor insists upon one course of action—cede not a grain of Roman territory, no matter the cost in lives or gold. Wary but loyal, Belisarius’ patchwork forces fight their way to Dara, a distant fortress-city along the Empire’s borders. Yet Persia’s commanders also have their designs upon Dara, and are eager to finally vanquish their hated Roman enemies. For Belisarius and Varus, resisting the Persian assault is not only a matter of personal survival, but shall determine the very fate of a dying Roman world.
