In the first chapter of this epic trilogy, the outcome of the historic War of the Ancients is forever altered by the arrival of three time-lost heroes: Krasus, the dragon mage whose great power and memories of the ancient conflict have inexplicably diminished; the human wizard Rhonin, whose thoughts are divided between his family and the seductive source of his now-growing power; and Broxigar, a weathered orc veteran who seeks a glorious death in combat. 

Since the beginning of time, the angelic hosts of the High Heavens and the demonic hordes of the Burning Hells have been locked in a struggle for the fate of all creation. That struggle has now come to the mortal realm...and neither man nor demon nor angel will be left unscathed.... 

Uncertainty plagues Azeroth’s ancient guardians as they struggle to find a new purpose. This dilemma has hit Kalecgos, youngest of the former Dragon Aspects, especially hard. Having lost his great powers, how can he―or any of his kind―still make a difference in the world? 

Since the beginning of time, the angelic forces of the High Heavens and the demonic hordes of the Burning Hells have been locked in eternal conflict for the fate of all Creation.

This is the tale of the Sin War - the conflict that would forever change the destiny of man.
