The Horus Heresy: Book Six – Retribution

The Horus Heresy Book Six - Retribution is the sixth book in the Horus Heresy series by Forge World. It covers the Shadow Wars of the Heresy: actions by the Knights-Errant, Shattered Legions, and Blackshields.

The Horus Heresy Book Six - Retribution continues the unfolding saga of the Horus Heresy. As the fires of total war consume entire worlds and whole Legions clash, away from the front lines the Knights-Errant are abroad too, penetrating the warp storms that afflict the entire galaxy as they carry out a mission bestowed upon them by the very highest authority on distant Terra. The Shattered Legions pursue bloody vengeance against the hated Traitors, who in turn seek to hunt the Loyalist survivors down no matter where they might seek refuge. Blackshields — orphaned or outcast Legiones Astartes who have renounced their Legions and obscured their heraldry - harbour their own objectives, alone in the darkness, sometimes aligned with the Traitor cause, sometimes the Loyalist, but just as often for their own unknowable ends.

This book explores the unseen Shadow Wars that raged across the entire galaxy as betrayed Legiones Astartes mounted bitter campaigns against their former brothers, determined that if death was to be their fate, their betrayers would share it. This tale is told across five chapters, describing five very different Shadow Wars of the Age of Darkness. Also included are a detailed campaign system and a set of special Shadow Wars missions, enabling players to undertake their own series of linked battles fought between the types of forces explored throughout the book.
