Changes

During the Crusade, Khârn served as Angron's [[equerry]], often acting as a voice of reason that cooled his primarch's bloody rages (a surprising contrast with the person Khârn was destined to become). Like the other World Eaters, he underwent extensive surgery, increasing his aggression such that he now finds joy only in killing the enemy. His love of killing is so great that he has actually had a kill counter installed in the lens of his helmet. This kill counter was made from arcane technology and was a gift from the [[Warmaster]] [[Horus]] himself.{{Fn|6}}.

During the infighting on [[Isstvan III]], Khârn was believed killed in action while fighting [[Garviel Loken]] of the [[Luna Wolves]], a [[loyalist]] determined to stop [[Horus]]. Khârn engaged in close combat with Loken, only to be thrown against the dozer blades of a nearby vehicle, impaling his chest. It was believed that the blow was fatal, but this proved false.{{Fn|3}} His mangled body was recovered by his friend, [[Apothecary]] [[Kargos]], who saved his life.{{Fn|12a}}

By the time of the [[Siege of Terra]], Khârn was barely able to hold back the urge to murder anything around him, even valued comrades such as [[Lotara Sarrin]]. After hearing that [[Mortarion]]'s [[Death Guard]] would instead be the first to assault Terra, Angron fell into a rage and massacred all he came across within the bowels of the ''[[The Conqueror]]''. [[Lotara Sarrin]] feared that he would murder the [[Tech-Priest]]'s attending to the vessels reactor, risking a catastrophic meltdown. This forced Khârn to confront Angron within the ship, where the Primarch revealed he knew of the 8th Captain's ultimate destiny and wished to supplant him as the Chosen of Khorne. The two battled, with Khârn being little match for his gene-father. However before Angron could finish him, Khârn placed a teleport homer on the Primarch which transported him to the shifting maze within the nearby [[Night Lords]] flagship ''[[Nightfall]]'' within, Angron became trapped and spent his time battling the many traps within the maze.{{Fn|20}}

Khârn next appeared leading an attack from a [[Spartan Assault Tank]] on the [[Lion's Gate Spaceport]], though the attack faltered in the face of the Emperor's psychic shield of the [[Imperial Palace]].{{Fn|22}} During the renewed assault on the Spaceport, Khârn fought alongside [[Abaddon]], [[Kroeger]], and [[Zardu Layak]]. Almost completely feral from the Butcher's Nails and influence of Khorne, Khârn penetrated deep into the Imperial lines in order to battle [[Sigismund]]. The two former allies dueled, and while Sigismund was the superior swordsman he could not match the Khornate power swelling through Kharn. Sigismund was only saved thanks to [[Rogal Dorn]], who swatted away the berserk Khârn like an insect. Khârn was only saved from death due to a rescue launched by Abaddon.{{Fn|22a}} Later Khârn and Angron both led a massive World Eaters assault on the [[Eternity Wall Spaceport]]. As the Port fell, Khârn slew [[Sisters of Silence]] Commander [[Jenetia Krole]]without even realizing what he had killed.{{Fn|23}}

During the drive into the [[Inner Palace]], Khârn was at the forefront of every assault. However he was eventually confronted by the [[Imperial Fists]] [[First Captain]] and his old sparring partner [[Sigismund]]. In the battle that followed not even Kharn's Warp-infused might could best the Imperial Fist, who much to his frustration refused to speak or acknowledge the World Eater. Finally Khârn was struck down by Sigismund, but before the final blow was struck the World Eater Captain remarked that even he was not as damaged as the embittered Sigismund had become. Sigismund then slew Khârn upon the soil of his original homeworld.{{Fn|24}} After this point, an apparition of Khârn stalked the halls of the ''Conqueror'' alongside the wraith of his long-time comrade Lotara.{{Fn|29a}} When Lotara's ghost finally began to realize that her physical self had mutated into an undead monstrosity, the apparition of Khârn warned her not to look until eventually admitting that the monster was the ''true'' Lotara. Afterward, both spirits faded away.{{Fn|29b}} After Horus was defeatedon Terra, his Khârn's fellow World Eaters carried his corpse away with them as they fought their way back to their ships. Once on board they discovered that by some dark miracle, he still lived.{{Fn|1a}} Whether Khorne himself breathed life back into the berserker's body or whether the relentless clamour of battle revived his blood-lusting spirit remains a mystery, but since the Heresy Khârn has survived the bloodiest battles to the current age and never came so close to death again.{{Fn|1a}}
