The Sons of Horus, originally known as the Luna Wolves, were the Sixteenth Legion of the Legiones Astartes, led by Horus Lupercal – the first discovered Primarch and later Warmaster of the Imperium. They hailed from Cthonia, a world whose gang culture shaped their aggressive and pragmatic style of warfare.

As the most powerful Legion of the Great Crusade, the Sons of Horus were feared for their ability to end conflicts swiftly and brutally. After Horus’s betrayal, they became the core of the Traitor forces and led the assault on Terra during the Siege of the Imperial Palace. Their loyalty to Horus was absolute – until his death at the hands of the Emperor.

In the Horus Heresy game system, the Sons of Horus have access to units such as Justaerin Terminators, Reaver Attack Squads, and Maloghurst the Twisted. Their rules emphasize aggressive assaults, flexible formations, and psychological pressure on the enemy. Their combat style is uncompromising, elite, and deadly.
