Khârn the Betrayer - Post-Heresy: The story of the World Eaters' search for a homeworld in the Eye of Terror is a defining point in the history of Khârn. It was during this time that the former Equerry would become both legendary and infamous amongst the berserk warriors of his Legion. After the Siege of Terra, many looked to Khârn to lead the World Eaters, now that Angron had ascended to daemonhood and once again spurned his Legion.The first thing the World Eaters required was a home within the Eye of Terror, a place from which to build their strength and strike back at the hated Imperium. It was a search that would lead them to the Daemon World of Skalathrax. A cursed place once inhabited by the Aeldari before the Fall, it was also coveted by the Emperor's Children, who desired the ancient xenos' Soul Stones for their debased god to feed upon. It was not long before the two Traitor Legions were engaged in bitter and bloody war for control of the world, with Khârn at the forefront of the fighting. However, the presence of the Legions had broken the ancient equilibrium of Skalathrax, and as they struggled an unnatural cold crept in from the void.Horrified by the conditions that affected even their superhuman metabolisms, the Traitor Astartes of the Emperor's Children and the World Eaters agreed to a temporary ceasefire, and both sides took to their shelters, for the freezing night brought conditions so severe that they could kill even a Chaos Space Marine in a matter of mere moments during the deepest portion of the night.Khârn fell into a terrible rage over the idea of being delayed from his slaughter for even a single night. Enraged when he saw his fellow Legionaries creeping back to their shelters like cowards, he took up a Flamer and used it to destroy the shelters, starting a fire that soon burned out of control, and he rampaged through the dying world killing both World Eaters and Emperor's Children with equal fury. His Flamer burned many Legionaries to ash as his chainaxe Gorechild slayed those who tried to stand against him.During the ensuing chaos, Khârn was assaulted by three unknown assailants. Undeterred, the berserker leapt at his foes. A stray Bolter round struck Khârn in his breastplate, sending his leap wide, forcing him to dispatch the concealed warrior with an improvised backhand strike of his chainaxe. He then whirled around and clove through the Bolter of the third assailant before slamming him insensible to the ground. Khârn quickly hurled Gorechild to his left. The chainaxe bit deep into the throat of the last Astartes, arterial blood spraying into the air. Standing over the prone warrior as he attempted to scrabble for his weapon, Khârn recognised the face of his assailant -- it was his old Centurion Gruner.Backed into a corner amongst the bodies of their fallen brethren, Gruner spoke of madness and betrayal, cursing Khârn for daring to strike down the battle-brothers of his own Legion. But Khârn merely laughed at his words: as the foremost berserker champion of the XII Legion, Khârn had stood upon the walls of the Imperial Palace. He was the last to be borne away from Terra, his body broken after he had slain one million of the False Emperor's lackeys through the breach at the Lion's Gate.None would ever surpass his tally of kills. The Contest was finally over, and he had been its victor. Khârn believed that the weakness of his fellow Heretic Astartes was the reason that they were defeated during the Siege of Terra -- the weakness of the other Traitor Legions as well as that to be found amongst the World Eaters.Filled with disgust for his fellow Astartes' weakness, the Chosen of Khorne beheaded his former training officer and continued to slay Emperor's Children and World Eaters alike throughout Skalathrax's murderous night, earning him the title of "the Betrayer," single-handedly shattering his Legion's unity and reducing it to scattered, individual war bands of Khornate Berserkers. These shattered remnants of the Great Companies of the XII Legion would never reunite and fight as one again until the time of the First War for Armageddon, and would remain divided for the next ten millennia.
