Range: The Horus Heresy โ€” Legio Custodes

The radiation-blasted world of Kol in the Signus Cluster played host to some of the most secretive battles of the Horus Heresy. Here the Legio Custodes would take the fight to Traitors, rebellious members of the Solar Auxilia, and even the accursed daemonic spawn of the entity known as Slaanesh.

The Corruption of the Signus Cluster

This gaming supplement for Warhammer: The Horus Heresy details the actions of the Legio Custodes in the Signus Cluster, the battle they fought on the cursed world of Kol, and the fate of those that died there. In addition to the tale of this conflict, this journal contains a Legendary Mission to refight key moments in the iconic war for the Signus Cluster. It also contains rules for all of the factions involved in that struggle, including rules which allow players to field the Daemons of Slaanesh in the Horus Heresy for the first time.

This 48-page softcover supplement contains:
โ€“ In-depth Lore: Detailed background on the Custodiansโ€™ role in the battles for the Signus Cluster, and of the traitorous forces arrayed against them.
โ€“ Additional Mission: A full Legendary Mission that allows players to refight a claustrophobic Zone Mortalis battle between beleaguered Custodes and the forces of Slaanesh.
โ€“ Daemons of Slaanesh Army List: A full Army List for the Daemons of Slaanesh.
โ€“ Unit Profiles: Additional rules for the Ephoroi Venatari-Proconsul, Hykanatoi Proconsul-Delegate, and Gyrfalcon Jetbike Sodality units for the Legio Custodes, as well as Exalted Section unit rules for representing Slaanesh-serving Solar Auxilia units.

You will need the Warhammer: The Horus Heresy โ€“ Age of Darkness Rulebook, Journal Tactica: Zone Mortalis, Liber Custodes, Liber Hereticus, and Liber Auxilia, all available separately, to make full use of this gaming supplement.
