One of the greatest deployments of the Legio Custodes outside of the Siege of Terra, the attack on Prospero saw hundreds of Custodians descend upon the Thousand Sons’ home world, led by Constantin Valdor himself. Their brutal assault on the city of Tizca and the Captain-General’s battle against the influence of the warp are chronicled in this new Journal Tactica.

This book contains extensive lore about the Legio Custodes and their deployments, alongside a new Cohort Doctrine, a new Legendary Mission, and rules for Adjutorum Sodalities – retinues of specialists to support your Shield Host.

The book also contains a Daemons of Tzeentch army list that brings Screamers, Horrors, and more to the battlefields of the Age of Darkness.
