Luna Wolves

The Luna Wolves were the XVI Legion of the Space Marines and derived from the geneseed of Horus who commanded them during the Great Crusade. In some continuities, they were renamed the Sons of Horus following their Primarch's appointment as Warmaster. In both the Scattering of Serenity and Heresy & Rebirth they provide the seed for the Black Legion.

Their heraldry was white armour with a wolfs head over a crescent moon. The Sons of Horus wore pale green armour with the Eye of Horus.

In Heresy & Rebirth, the Black Legion wear black armour marked only with simple rank badges. Rather than obeying a single commander, the Black Legion is led by a group of four Captains known as the Mournival.
