Driven from Chogoris, Huron continues to bait the White Scars throughout the burning ruins of the Yasan Sector, hungry for the victory he believes he deserves. Yet as his schemes and insults threaten to ensnare the sons of Jaghatai, a new threat emerges. Out of the tumult of the Cicatrix Maledictum, the Great Devourer pours into Huron’s domain. The tyranids threaten not only his war, but all he has built since the fall of Badab.
