When Horus fell, his Sons fell with him. A broken Legion, beset by rivalries and hunted by their erstwhile allies, the former Luna Wolves have scattered across the tortured realm of the Eye of Terror.

But when Horus's body is taken from its resting place, a confederation of legionaries seek out the former First Captain, to convince him to embrace his destiny and continue what Horus began.

Black Legion

by Aaron Dembski Bowden

Published 24 August 2017
The Sons of Horus may be no more, but rising from their ashes come the Black Legion. Returning after his long self-imposed exile, Abaddon offers the disparate Chaos Space Marine warbands within the Eye of Terror a simple choice – join him or die. As his newborn war host emerges from the Eye of Terror to ravage the galaxy, none can stand in Abaddon’s path, not even the Black Templars Chapter - sworn to stand guard at the storm’s edge -  nor the Emperor’s Champion himself.
