This round of Warhammer news mixes fresh Horus Heresy rules with three upcoming Black Library releases.
Custodes players gain new commanders that open very different army-building options. Meanwhile, Imperial Knights return to fiction with court politics, disappearing war machines, and a mysterious winter. Black Library also revives two older favorites in premium editions.
Assault on Kol Expands the Legio Custodes

Assault on Kol shifts attention away from Signus Prime and toward a little-known battle beneath the planet Kol. The world’s mines became military bases and hives, where Chaos corrupted the Solar Auxilia’s 606th Cohort, the Rad Serpents. Meanwhile, Slaanesh daemons spread through the tunnels as Sanguinius fought elsewhere across the Signus system.

A Custodes splinter force investigated Kol, and the supplement introduces commanders suited to representing that mission. The Ephoroi Venatari-Proconsul fills a Command Slot with Weapon Skill 6, Ballistic Skill 7, and Movement 14. Better yet, a Venatari jump pack grants Antigrav, making this leader perfect for fast, terrain-hopping attacks. Notably, players can keep twin Kinetic Destroyers or swap one for an AP2 Vaultsword with Precision 4+.

Most importantly, this commander finally makes an entire Venatari-led Custodes force possible. In contrast, the Hykanatoi Proconsul-Delegate offers a cheaper 80-point commander for smaller armies or Allied Detachments.

Although only Weapon Skill 5, the Delegate can carry a sentinel warblade, praesidium shield, or guardian spear. Likewise, both profiles are intended for kitbashed miniatures, with suggested components included in the Journal Tactica. Finally, Gyrfalcon Jetbikes gain the plastic kit’s arachnus volley cannon with Burst and Concentrated firing modes.
Throne Questoris Leads a New Black Library Wave

Throne Questoris follows Asrien Balateur, an Imperial Knight scion preparing to inherit a throne as their world begins collapsing. Mysterious snowstorms swallow the land, while Knights disappear among ruined castles and devastated realms. At the same time, old debts and buried madness turn court politics into something far more dangerous. Victoria Hayward mixes knightly intrigue with massive war machines, which sounds like fertile ground for Imperial Knights fiction.

Beyond that, Cypher: Lord of the Fallen returns as an Illustrated and Annotated Edition. That version adds a John French introduction, commentary, and new artwork throughout Cypher’s escape from Terra.

Additionally, Ben Counter’s Grey Knights returns as an ornate Special Edition. Its story pits the Chapter against Ghargatuloth after a thousand-year banishment expires exactly as prophecy foretold. Finally, all three books are coming to pre-order soon.
Final Thoughts
Overall, this Warhammer news has plenty for lore-focused players. Custodes receive genuinely useful army-building tools, while Black Library delivers both new fiction and worthwhile returning classics. More importantly, both releases dig into corners of their settings that deserve more attention.
