Return to the hidden wars of the Signus Cluster with this Warhammer: The Horus Heresy gaming supplement, focused on the Legio Custodes and the brutal fighting that engulfed the radiation-blasted world of Kol.

This 48-page softcover supplement explores the Custodians’ role in the conflict, including their battles against Traitor forces, rebellious Solar Auxilia, and the daemonic servants of Slaanesh. Alongside the narrative background, the book includes new rules, unit profiles, and a Legendary Mission for recreating key moments from the campaign.

For the first time in the Horus Heresy, players can also field a full Daemons of Slaanesh Army List, adding an entirely new faction to the Age of Darkness.
