Angron - Rebellion: Within a few standard years Angron's fame had spread to every corner of his homeworld. Under his training, the gladiators of his arena soon became the greatest their world had ever seen and none could stand against them.Yet Angron also learned, following a final failed escape attempt, that he would never succeed alone. His unbending warrior's code and sheer combat skill had made him a well-respected leader amongst the other Desh'ean gladiators and when the largest death games ever held on Nuceria were announced, Angron planned his most daring escape attempt.For these new games, Angron was allowed to stage a vast combat that would involve every gladiator of his arena. As the Desh'ean crowd drowned out the sounds of battle, Angron's gladiators turned on their armed guards, butchering them and fighting their way to freedom. Against the guards armed with firearms, the gladiators' casualties were grievous, but nearly 2,000 survived to escape into the streets of Desh'ea, stealing what weapons and supplies they could before fleeing into the northern mountains where Angron had first been discovered.Over the next few years, the rulers of the world dispatched many armed forces to kill or recapture the rebel slaves, who soon named themselves the "Eaters of Cities," but all were destroyed in turn by Angron's leadership, martial skill and the cybernetically-enhanced fury of the gladiators. But attrition and hunger slowly took their toll on the slaves and eventually only 1,000 men and women remained, half the size of the original force of escapees.On a mountain named Fedan Mhor, on a bleak spit of land known as Desh'elika Ridge, Angron and his forces were finally surrounded by no less than seven large Nucerian armies. Not even a primarch could stand against such sheer numbers, yet it was at this time that the Emperor of Mankind came to Nuceria, drawn by the psychic emanations of his gene-son the primarch.The Emperor had observed Angron secretly from orbit for many solar months and had watched with pride as he had led his freed slaves in battle against the forces of tyranny. The Emperor and a small cadre of Legio Custodes descended to the world's surface, and after the shock of the august meeting had worn off on the primarch, the Emperor offered Angron the leadership of the XIIth Space Marine Legion, the War Hounds, which had been created from Angron's own genetic material, and a place at his side in the Great Crusade.To the Emperor's disbelief, Angron refused, claiming that his place remained with his fellow slaves amongst the Eaters of Cities and he would die before deserting them. Reluctantly, the Emperor teleported back to His flagship, shocked at His son's refusal.Appraising the situation, the Emperor saw that for all of Angron's might as a primarch and a leader, he would die in the coming battle. Losing one of His irreplaceable sons to the assault of rabble on a backwater planet soon to be brought into Imperial Compliance was simply unacceptable.Bringing His flagship into low orbit over the world, the Emperor teleported Angron from the surface against his will, away from the mountain of Fedan Mhor and the Battle of Desh'elika Ridge. Without their leader, the morale of the gladiators was destroyed and the next day they were slaughtered to the last warrior by the armies of Nuceria's rulers.Angron watched helplessly from orbit as his brothers and sisters were quickly annihilated. Sensing his uncontrolled rage, the Custodians surrounded Angron, their Guardian Spears pointed menacingly at the smoldering primarch. In a fit of sudden violence, Angron killed one of the Custodians, but the Emperor intervened and the primarch was forced into a state of submission by the Emperor's potent psychic abilities.Angron angrily asked his father why He had not intervened to save the lives of his comrades on the planet below, but the Emperor dismissed the question as lacking vision. He was the Emperor of Mankind, and He possessed a much grandeur vision for Human life such as reuniting the galaxy on behalf of all Humanity. He had little concern for a small group of former slaves battling a group of petty tyrants on a backwater world.The Emperor expressed His hope that in time, Angron would come to understand His actions and why He had done what He did. Angron replied that he had been meant to die alongside his comrades on Nuceria, and now only a ghost remained. The Emperor replied that a ghost would suffice for what he had planned for his son.Allowing his fellow gladiators to die was a deed Angron would never forgive the Emperor for, and a stain upon the primarch's honour that would never fade but fester into a soul-deep wound.The exact records of the Emperor's intervention and Angron's acceptance of his new circumstances is a matter of shadowed rumour and conjecture, but what can be said with certainty is that Angron's first reaction to his new life was simple rage. For some time any War Hound of his Legion who came before their primarch was met with a grisly death for their efforts.At this time the Legion Master of the War Hounds, Ibram Ghreer, a respected leader who had commanded the XIIth Legion for nearly three solar decades, disappeared without explanation from any records of the period and no explanation was given by his taciturn Legion for his absence. Only after murdering at least seven high-ranking officers within the Legion, including Ghreer, Captain Khârn of the 8th Assault Company voluntarily went forth to Angron's private quarters to confront the always enraged primarch.Nearly beaten to death for his efforts, Khârn's unwillingness to accept defeat even at the hands of a much superior foe finally convinced Angron of his Legion's worthiness and honour as fellow warriors, and he assumed his place as the rightful general and commander of the XIIth Legion.Khârn manged to form a rapport with Angron, talking about the rituals of Angron's gladiators and the traditions of the War Hounds, and showing how similar they were to each other.With Khârn's actions convincing him of the worthiness of his Astartes to become his new band of warriors, Angron finally and swiftly took charge of the XIIth Legion. The primarch renamed the War Hounds the "World Eaters" after he assumed command.Angron did this in part to honour the gladiator force he had led in rebellion on his homeworld whose warriors had been known as the "Eaters of Cities" for their wrath and violence. He chose the new name for his Legion when Dreagher, a Terran-born War Hounds Legionary who served as Captain of the Legion's 9th Company, promised Angron after meeting his primarch for the first time that under his leadership the War Hounds would become, "...the eaters of worlds."Soon after, the newly renamed World Eaters were influenced by Angron's own thirst for battle. During the course of the Great Crusade, Angron and the World Eaters reaped many victories, although some criticised the extreme and bloodthirsty tactics the Red Angel used to ensure the destruction of his opponents.
