After seven years of bitter war, the end has come at last for the conflict known infamously as the Horus Heresy. Terra now lies within the Warmaster’s sights, the Throneworld and the seat of his father’s rule. Horus’ desire is nothing less than the death of the Emperor of Mankind and the utter subjugation of the Imperium. He has become the ascendant vessel of Chaos and amassed a terrible army with which to enact his will and vengeance. But the way to the Throne will be hard as the primarch Rogal Dorn, the Praetorian and protector of Terra, marshals the defences.

In the foreboding north, the demonic hordes of the magic-twisted hellscape known as the Worldwound encroach upon the southern kingdoms of Golarion. Their latest escalation embroils a preternaturally handsome and coolly charismatic swindler named Gad, who decides to assemble a team of thieves, cutthroats, and con men to take the fight into the demon lands and strike directly at the fiendish leader responsible for the latest raids - the demon Yath, the Shimmering Putrescence.

In the grim nation of Nidal, carefully chosen children are trained to practice dark magic, summoning forth creatures of horror and shadow. Isiem is one such student, a promising young shadowcaster whose powers are the envy of his peers. Upon coming of age, he's dispatched on a mission of genocide against the winged humanoids of Devii's Perch. Yet as the body count rises and Isiem comes face to face with the people he's exterminating, lines begin to blur, and the shadowcaster must ask himself who the real monsters are....

When a mysterious monster carves a path of destruction across the southern River Kingdoms, desperate townsfolk look to the famed elven ranger Elyana and her half-orc companion Drelm for salvation. For Drelm, however, the mission is about more than simple justice - it's about protecting the frontier town he's adopted as his home, and the woman he plans to marry.

Gideon Gull leads a double life: one as a talented young bard at the Rhapsodic College, the other as a student of the Shadow School, where Taldor's infamous lion blades are trained to be master spies and assassins. When a magical fog starts turning ordinary people into murderous mobs along the border between Taldor and Gideon's home nation of Andoran, it's up to him and a crew of daring performers to solve the mystery before both nations fall to madness and slaughter.
