Black Legion

About the Black Legion series

Black Legion is Aaron Dembski-Bowden's account of the Traitor Legions' lowest, most fractured point -- the decades after the Horus Heresy's defeat, when the Sons of Horus have scattered and the wider Chaos-aligned galaxy has all but forgotten Abaddon, the former First Captain who will eventually reforge them into the Black Legion. It's narrated by Iskandar Khayon, a former Thousand Sons sorcerer, recounting the story under Imperial Inquisition custody -- a framing device that lets Dembski-Bowden write almost entirely from the traitors' point of view without ever fully trusting his narrator.

The Talon of Horus (2014) follows Khayon and a small confederation of legionaries hunting through the Eye of Terror for Abaddon himself, hoping to convince him to pick up what Horus started; Black Legion (2017) pushes further into the warband's fracturing loyalties and the cost of the choice they've made. It's a direct spiritual sequel to Dembski-Bowden's Horus Heresy novels (The First Heretic, Betrayer), following some of the same Legions decades on, and one of Black Library's few series willing to spend an entire trilogy inside the psychology of the 40K setting's ostensible villains.
