At The Big Summer Warhammer Preview Show 2026 event, Games Workshop unveiled the "Custodes Support Battle Group" set, which includes four "Kreshet" grav-bikes, a "Pallas" grav-cutter, and a "Telemon" heavy dreadnought. All of them can be used in both the Warhammer 40,000 tabletop game and Warhammer: The Horus Heresy.

The multi-part plastic dreadnought comes with a full set of primary weapons. You can choose the "Telemon" caestus with a twin neutronium cascade projector, an "Arachn" storm cannon, an adrathic annihilator, or an "Iliastus" cannon. Its intricately crafted chassis is complemented by decorative elements, and a "Spiculus" mount is placed on its shoulders.
Each of the four grav-bikes included in the set can be equipped with one of four weapons: an adrathic devastator cannon, a "Lastrum" bolt cannon, a twin "Corvus" laser pulsator, or an "Arachnus" blaze cannon. The rider can either hold a power spear in hand or leave it mounted on the hull.
The "Pallas" grav-cutter is capable of piercing enemy armor with its twin "Arachnus" plasma cannon or destroying elite warriors with its twin "Iliastus" cannon. Rules for using all three of these units in Warhammer: The Horus Heresy games can be found in the Liber Custodes: The Forces of the Emperor book.
It will be possible to acquire the "Burning of Prospero" tactical journal. It contains extensive background on the Legio Custodes and their deployments, as well as a new cohort doctrine, a new legendary mission, and rules for Adjutorum Sodalities.
Additionally, the book includes a Tzeentch Daemon army list, bringing Screamers, Horrors, and other creatures to the battlefields of the Age of Darkness. The new box and book will be available for pre-order later this year.
