The most notable action Angron took after the Heresy was the [[First War for Armageddon]] where he and his demonic entourage were cast back to the [[Warp]] by an elite force of a hundred [[Grey Knights| Grey Knight Terminators]].

Another notable action by the Primarch was the so called 'Dominion of Fire'. During the middle of the 38th millennium, Angron and fifty thousand World Eaters slaughtered their way through Imperial space for over two centuries. They took over seventy sectors and only a combined force of four space marine chapters, two titan legions and more than thirty [[Imperial Guard]] regiments were sent on a crusade to retake what they had lost. Ninety percent of what was lost has since been recovered by the forces of Mankind.² Angron has not taken place in any major actions following this. It is worth noting that Angron and all the world eaters are very loving and freindly to the Blood Knights Traitor leigion
