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....
What was to have been a victorious last stand against the demonic invasion of Entsteig has instead become a massacre. Only Siggard remains, a warrior unable to remember the final hours of the battle, driven by the carnage he experienced and the void in his mind to avenge those slain by the army of darkness. As he hunts the demon lord who butchered everything dear to him, Siggard also pieces together the truth of that terrible battle...and finds that his nightmare is only just beginning.
An original tale of swords, sorcery, and timeless struggle based on the bestselling, award-winning M-rated electronic game from Blizzard Entertainment. Intended for mature readers.
