Words alone can no longer convey the horrors of the war that now grips the Imperium. In what should have been an age of enlightenment and glorious triumph, instead warriors on both sides reel from the twin agonies of betrayal and bloodshed. The hatred of a sworn foe, the ire of a primarch, or the unholy wrath of a daemon-lord - none but the mighty Space Marines can hope to weather such torments unscathed... This anthology contains five exclusive stories from across the battlefields of the Horus Heresy. Each tale ties into one of the major arcs of the series so far, from the worlds of Imperium Secundus, to the palace of Terra, and even the Warmaster’s Flagship, The Vengeful Spirit. Virtues of the Sons by Andy Smillie Amit duels Khârn and Azkaellon faces Lucius as Sanguinius' chosen sons explore the twin aspects of their nature. Imperfect by Nick Kyme A simple game of Regicide between Fulgrim and Ferrus Manus is far more than it seems... Howl of the Hearthworld by Aaron Dembski-Bowden A Space Wolves pack rails at being sent back to Terra to watch over Rogal Dorn. A Safe and Shadowed Place by Guy Haley Seeking refuge, the remnants of the Night Lords fleet stumble across Imperium Secundus. Gunsight by James Swallow An Assassin lurks on board the Vengeful Spirit. His target? Warmaster Horus himself.
