- First War for Armageddon (444.M41) - The Daemon Primarch Angron, the favoured Champion of Khorne, reunified his World Eaters after the Battle of Skalathrax, and led the XII Legion once again deep into the heart of the Imperium. They invaded the Hive World of Armageddon in 444.M41, in a lesser known conflict that would come to be known as the First War for Armageddon. The Khornate warband called Angron's Chosen sent an entire company of Khornate Berserkers in support, who carved a bloody trail of slaughter across the doomed planet. But in the end, victory was denied to the Forces of Chaos due to Angron's own foolish belief in his victory before completing a total conquest of the world and the successful intervention of the Grey Knights Chapter of Space Marines. The Grey Knights assault banished Angron back to the Warp for a thousand standard years and led to the failure of the overall campaign. During the World Eaters' withdrawal a portion of the Foresworn warband was left behind on Armageddon.
Angron's Chosen wear the colours of the devotees of the Blood God; blood-red Power Armour with brass trim and black.
Angron's Chosen's badge is the same as that of their parent Traitor Legion, the World Eaters, which is a fanged maw engulfing a world. Some warriors wear a modified version of this symbol which omits the world, using only an open, large, fanged maw.
