Originally know as the Lunar Wolves, the Legion was renamed in honor of their Primarch to be know as the Sons Of Horus. They were again renamed after the defeat of the Chaos forces and the death of Horus to The Black Legion. Currently led by Abaddon the Despoiler, this legion embodies the power of Chaos undivided, constantly shifting their allegiances between the Chaos God and often inviting possession by Daemons.
