Dive into the forgotten war on the cursed world of Kol, where the Legio Custodes fought a brutal battle against cultists, Traitors, and the daemonic forces of the Warp. Packed with lore and new rules, this book brings one of the Adeptus Custodes' darkest conflicts to life while expanding your options on the tabletop.

Inside, you'll find new rules for the daemonic legions of Slaanesh, plus a Legendary Mission that recreates the dishonoured Shield-Captain Medraut's assault on Kol's corrupted subterranean hive city network. The book also introduces two new Custodian Proconsul units and provides updated rules for Gyrfalcon Jetbike sodalities, giving you even more ways to field your Custodes.
