Emperor's Children - Notable Emperor's Children: Fulgrim (Daemon Primarch) - Fulgrim the Phoenician was the Primarch of the Emperor's Children Legion and later became a Daemon Prince of Slaanesh. Fulgrim regretted his corruption by Chaos and repented of his actions after he slew his brother Primarch Ferrus Manus of the Iron Hands Legion during the Drop Site Massacre on Istvaan V. However, the spiritual weakness produced by this moment of clarity led Fulgrim to surrender control of his body to possession by the Greater Daemon of Slaanesh that inhabited the Daemonsword he had taken from the xenos world of Laeran. The real Fulgrim became a prisoner in his own body, the state of his soul revealed in a painting kept on the Emperor's Children Legion's flagship Pride of the Emperor, while the possessed Fulgrim went on to lead his Legion to ever greater heights of nurder and debauchery in the eyes of the Prince of Pleasure. But Fulgrim used his captivity to master the ways of the Warp and ultimately cast the daemon from his body, retaking his rightful place yet having also progressed even further along the path of Chaos as set forth by the Prince of Pleasure. Fulgrim was ultimately raised to become a Daemon Prince of Slaanesh and now dwells on an unknown Daemon World in the Eye of Terror. The soul of the real Fulgrim remains trapped in a nightmare from which he can never wake.Eidolon (Lord Commander) - Eidolon was the first Space Marine selected by Fulgrim to lead an entire company. He was commonly regarded as the most proficient of all the Lord Commanders of the IIIrd Legion and had been a dedicated student of the art of warfare in all its aspects. He was decapitated by Fulgrim with the Chaotic blade known as the Kinebrach Anathame after he dared to question why Fulgrim had ordered the IIIrd Legion to assault the relatively unimportant Adeptus Mechanicus world of Prismatica V. In a moment of remorse, Fulgrim ordered Chief Apothecary Fabius to restore the slain Lord Commander back to life, though his resurrection had unforeseen side-effects. Eidolon would live with pain like no other, driving the Lord Commander mad with joy as a result of his corruption by Slaanesh. Every instant of life given to him would be spent in a symphony of pain and pleasure. Forever after, he would be referred to by his brothers simply as "The Risen". Unsubstantiated rumours persist that Eidolon yet lives; and that he is responsible for hundreds, if not thousands of raids upon Imperial worlds over the last ten standard millennia. Unsubstantiated evidence suggests Eidolon has served as a lieutenant to Abaddon the Despoiler, a consort to Queen Sylelle as well as a champion of the Daemon Prince N'Kari.Vespasian (Lord Commander) (Deceased) - One of two senior Lord Commanders of the IIIrd Legion during the Great Crusade era. Unlike his counterpart Eidolon, Vespasian was immensely likeable, for his incredible abilities as a warrior and commander were tempered by a rare humility that made others warm to him immediately. In the manner of the Emperor's Children, warriors who followed Vespasian would take their lead from him in all things, his example serving as a model of how they might best achieve perfection through purity of purpose. Following the campaign against the Laer, over time a rift soon grew between the once-favoured Lord Commander and his Primarch. Eventually, Vespasian confronted Fulgrim in his staterooms over the growing rot and decay of the ideals that their Legion was founded on. To his horror Vespasian discovered too late the malign influence that held sway over his Primarch. Fulgrim murdered Vespasian by stabbing him in the neck with his cursed sword.Anteus (Lord Commander) - Lord Commander during the Great Crusade and Horus Heresy eras.Cyrius (Lord Commander) (Deceased) - Following the Horus Heresy, Lucius finally met his match in swordsmanship, when the two Emperor's Children Astartes dueled. His agonising death was an experience of transcendent pleasure, but Slaanesh was loath to let such a promising protege slip into the realm of death. Over the following weeks, the artificer armour Cyrius wore began to warp and change. His hair fell out in clumps, and dark lines appeared under his flesh, slowly pushing through his skin as a maze of scar tissue. Soon, Lucius emerged completely, and all that remained of his executioner was a screaming, writhing face, subsumed for eternity into Lucius's armour.Iddinam (Lord Commander) (Deceased) - Lord Commander Iddinam was the commander of an Army Group of Emperor's Children charged with bringing the Praxil system into Imperial Compliance in order to acquire its vast wealth and resources without damaging the delicate infrastructure. The Emperor's Children were supported by selected elements of the Imperial Army and the military forces of the Mechanicum. Despite meticulous planning, the campaign did not begin well, as substantial losses were inflicted upon the Imperial forces. Changing their strategy, the Emperor's Children decided that instead of focusing on systematic conquest of the system's void stations, moons and planets, they would instead focus upon Praxil's fleet. Without the ability to redeploy their strength, each of the Praxil domains would become a closed tactical problem. But the Praxil had anticipated such tactics, and instead deployed multiple strike fleets to attack the Imperial fleet. Heavy further losses were incurred during this initial engagement as the Praxil took advantage and attacked the Imperial toehold on their outer moons and space stations. A representative of the War Council of Terra observed that Lord Commander Iddinam would never willingly admit that he needed assistance, and therefore issued a request to Terra for reinforcements. Soon elements from the Blood Angels under the command of Chapter Master Raldoron and Marshal Cazimus of the Imperial Fists arrived in-system to augment the beleaguered Imperial forces. Despite his misgivings and the slight to his personal honour, the Lord Commander accepted his cousin Legions' assistance and immediately drew up plans for prosecuting the second offensive against the Praxil. Utilising the strength of the Blood Angels and Imperial Fists, the Emperor's Children launched a successful second offensive against the Praxil that soon saw an Imperial victory. When the Imperium claimed its victory, however, the Lord Commander refused to be present during the subsequent Compliance ceremonies or acknowledge his role in effecting the Compliance of Praxil afterwards. Iddinam would later have a hand as a prime conspirator of his Legion's treachery during the Isstvan III Atrocity. He gave himself over to the horrors of the Warp before finally being destroyed by the Loyalist Iron Warriors Warsmith Auric Saxton at the Battle of the Harrow Ravening.Illois (Lord Commander) (Deceased) - Killed during the Great CrusadeTeliosa (Lord Commander) (Deceased) - Hero of the Madrivane Campaign. Killed during the Great Crusade.Abdemon (Lieutenant Commander) (Deceased) - Abdemon was the Lieutenant Commander of the IIIrd Legion who prosecuted the xenocide of the Katara, as recounted above. It is said that Abdemon and members of his Cohort trained and fought with the weapons of the Katara, and bore these relics throughout the rest of the Great Crusade. Abdemon himself is believed to have died on the traitorous blade of one of his own captains on the field of the Choral City during the Istvaan III Atrocity.Fabius (Lieutenant Commander; Chief Apothecary) - Fabius Bile, now called the Clone Lord, was the Chief Apothecary and a Lieutenant Commander of the Emperor's Children Legion. After the Horus Heresy he left the IIIrd Legion and the path of Slaanesh behind to pursue his own agenda to unearth the secret genetic engineering knowledge that the Emperor of Mankind had used to create the Astartes. He is known to have unleashed genocide and hideous genetic experiments on countless worlds across the galaxy.Flavius Alkenex (Prefector) - Flavius Alkenex was a formidable warrior and prominent officer within the Emperor's Children Legion. He served within the upper echelons of the IIIrd Legion's organisation as a member of the elite Phoenix Guard Millenial of the Legion.Grythan Thorn (Decanus) (KIA) - Decanus Grythan Thorn was a known figure outside the IIIrd Legion, serving as equerry to Primarch Fulgrim during the Kobal Compliance campaign. Thorn was known to have been slain during the botched commandeering of the heavy cruiser Sunstone in the early stages of the Isstvan III Atrocity.Julius Kaesoron (First Captain) - Commander of the elite 1st Company. After Slaaneshi corruption consumed much of the IIIrd Legion, Kaesoron submitted to the surgical modification experiments of the Apothecary Fabius Bile and was transformed into one of the first Noise Marines. He gathered the other Noise Marines of the IIIrd Legion around him before the Drop Site Massacre on Istvaan V and formed the infamous unit that became known as the Kakophoni.Solomon Demeter (Second Captain) (KIA) - Solomon Demeter was a Captain of the 2nd Company of the Emperor's Children Space Marine Legion during the Great Crusade and opening days of the Horus Heresy. Unlike most Astartes of the Emperor's Children, he displayed the qualities of individualism, an exacting and perfectionist nature and recklessness that set him apart from his peers, making him stand out amongst the senior officers of the IIIrd Legion. During the opening days of the Horus Heresy, he remained loyal to the Emperor and the tenants of the Imperial Truth, and so was fated to be sent to the surface of Istvaan III, in what would become known in Imperial history as the Istvaan III Atrocity, to die alongside the other Loyalist elements of the Space Marine Legions under the direct command of Warmaster Horus. Though he survived the initial bombardment and was gravely wounded, he, along with other Loyalist survivors, fought a protracted campaign of attrition against the Traitor forces of the Warmaster. In a dark twist of fate, Demeter was betrayed by one of his own battle-brothers, dying at the hands of Captain Lucius.Marius Vairosean (Third Captain) (KIA) - Marius Vairosean was once the third Captain of the Emperor's Children Legion during the latter days of the Great Crusade and the Horus Heresy in the late 30th and early 31st Millennium. He was present during many of the most infamous campaigns of the Heresy, including the Istvaan III Atrocity and the Drop Site Massacre of Istvaan V. Marius' own quest for perfection would lead him and his entire Legion along the foul path of Chaotic corruption. Due to the influence of Slaanesh and the hideous ministrations of the Apothecary Fabius Bile, Vairosean was soon consumed by the corruption of Slaanesh and became one of the very first Noise Marines in service to the Prince of Pleasure. He eventually became the leader of the Kakophoni, the Noise Marines unit that formed within the Traitor Emperor's Children Legion after their fall to Chaos. During the joint expedition undertaken by both the Emperor's Children and the Iron Warriors Legion into the Eye of Terror to seek out the forbidden xenos weapon known as the Angel Exterminatus, Vairosean was killed by the Drop Site Massacre survivor Ignatius Numen, an Iron Hands Morlock.Saul Tarvitz (Tenth Captain) (Presumed KIA) - Commander of the 10th Company and staunch loyalist. Tarvitz was a file officer whom did not aspire to anything higher, despite being extremely competitive. Most troops that he lead greatly respected him, except Lucius, who was enraged the attention Tarvitz receives for his competent leadership. Captain Tarvitz was supposed to be in the initial drop-assault onto the surface of Istvaan III but had traded places at the last minute with the Dreadnought Ancient Rylanor. Discovering the treachery of the Warmaster Horus and his Primarch Fulgrim, Tarvitz willingly placed himself in the line of fire by going to the surface of the planet to warn his fellow Loyalists. Shortly after safely reaching the surface, Horus ordered the viral bombardment of the planet, but thanks to Tarvitz's last minute warning, some of the Loyalist forces were able to take cover in air tight bunkers. Tarvitz, along with his fellow Captains from the Luna Wolves, Garviel Loken and Tarik Torgaddon, managed to turn the rag-tag Loyalist survivors into a cohesive fighting unit. Tarvitz, a formerly unremarkable line officer, had transformed a planned massacre into a successful guerrilla war, confounding even the great Horus' best laid plans. Tarvitz, along with his fellow Loyalists apparently met their final fate on Isstvan III.Lucius the Eternal (Thirteenth Captain, later Lord Commander) - Lucius the Eternal is the current Chaos Champion of the Chaos God Slaanesh and a Lord Commander of the Emperor's Children Traitor Legion. Lucius is also known as the Soulthief, Fulgrim's Champion, and the Scion of Chemos. Lucius has been blessed by Slaanesh so that when he is slain, no easy task in itself, his killer will eventually transform into Lucius if he takes any pleasure or satisfaction from the killing. Lucius was once the Captain of the Emperor's Children Legion's 13th Company. He served alongside his friend and fellow Astartes officer, Captain Saul Tarvitz of the 10th Company, during the Great Crusade of the 31st Millennium. Lucius' friendship with Tarvitz often displayed those character flaws that lead to Lucius' ultimate damnation. Where Tarvitz was a grounded and mature Astartes, Lucius was often childish and egotistical, but already known within his Legion as a superlative swordsman. Lucius's character changed greatly during the early days of the Horus Heresy. The most obvious change was the appearance of the scars he carved ritually into his face, changing him from a flawless Space Marine into a corrupt tyrant who gloried in the sensation of dealing out pain. The reasons recorded for this disfigurement have varied. Some claim they express Lucius's "devotion and piety" towards the Chaos Gods, others that they were intended to deflect comments that he looked more like a boy than a warrior. In reality, Lucius met Slaanesh-corrupted Remembrancer and painter who accompanied the 28th Expeditionary Fleet named Serena D'Angelus. After showing Lucius her hideously scarred forearms, she explained that each scar was a memorial to one of her victims. Lucius, who had had his nose broken by Garviel Loken of the Luna Wolves, understood that his appearance would never be flawless again, and so scarred his face without remorse. After this meeting he added a scar to his body every time he met a worthy opponent, such as before duelling with his former comrade and best friend, Saul Tarvitz. Lucius' descent into the clutches of Chaos only deepened during the Battle of Istvaan III after Horus betrayed the Loyalists within his own Traitor Legions to cleanse his troops of any who remained beholden to the will of the Emperor. Originally forced to fight on the side of the Loyalist Astartes during the three-month-long battle on that devastated world because his friendship with Tarvitz had made the Legion's leaders believe he would not support their decision to betray the Emperor of Mankind, Lucius' pride and jealousy eventually overwhelmed him. Lucius came to resent Tarvitz's role in their success against the enemy and the respect he commanded from the other Loyalist Astartes. Lucius contacted Lord Commander Eidolon and promised to deliver Tarvitz -- and break the Loyalists' defences -- for the Warmaster in return for being reaccepted into the Legion. Eidolon accepted the proposal. Lucius slaughtered a group of 30 Astartes who were defending the Loyalists' lines to open the way for the Traitors' final assault against their former brethren. Lucius succeeded in this assassination with the aid of Captain Solomon Demeter of the 2nd Company of the Emperor's Children, who had also remained a Loyalist and realised too late that Lucius had tricked him into attacking a group of Loyalist Astartes. Lucius slew the wounded Demeter just after he realised with horror the full extent of his mistake and Lucius' betrayal. With his place restored in the ranks of the Traitors, Lucius then challenged Tarvitz to a one-on-one duel to finally determine who was the better warrior. Tarvitz emerged the victor, but Lucius fled the battle and returned to the arms of his Traitor Legion, having fulfilled his side of the bargain. Lucius returned to his Legion and ultimately led the other senior officers of the IIIrd Legion in a rebellion against their Primarch Fulgrim after Lucius came to believe that Fulgrim's body was possessed by a daemon of the Warp. In the course of these events, Lucius learned that while Fulgrim had been possessed by the Slaaneshi daemon that had once inhabited the Primarch's Laer daemonblade, that Fulgrim had reasserted contol over his own body and banished the daemon to imprisonment within the portrait of the Primarch that still remained in La Fenice, the ruined exhibition hall of the Battle Barge Pride of the Emperor. Awed by Fulgrim's perfection, Lucius then swore his allegiance anew to his corrupted Primarch. After these events, Lucius eventually rose to become one of two of the remaining Lord Commanders of the Emperor's Children, after that Traitor Legion had been cemented in thrall to Slaanesh. Lucius did not obtain that position easily, however, for he was actually slain during an Emperor's Children gladiatorial game by the Chaos Space Marine he had challenged for the rank, Lord Commander Cyrius. Lucius' death was described as an experience of such "transcendent pleasure" that it caused Slaanesh himself to intervene and to reincarnate Lucius within the body of the previously victorious Cyrius; the latter's soul became a trapped, screaming face within Lucius' Artificer Armour by the will of the Prince of Pleasure.Hellespon (Captain) - Captain during the Great Crusade and Horus Heresy eras.Tyrion (Captain) - Captain during the Great Crusade and Horus Heresy eras.Xiandor (Captain) - Captain during the Great Crusade and Horus Heresy eras.Odovocar (Captain) - Legion Standard BearerCharmosian (Chaplain) (Deceased) - Chaplain of the 18th Company, and one of the senior-most members of the Legion. He acted as a member of Fulgrim's honour guard during the latter stages of the Legion's corruption. He was killed by Lucius at Istvaan III when the pair dueled.Gaius Caphen (Lieutenant) - Second-in-command to Captain Demeter of the 2nd Company. Died of his wounds before the traitors land on Isstvan III. (KIA)Lycaon - Equerry to First Captain Kaesoron of the 1st Company.Abdle Comendius (Apothecary) (Deceased) - Apothecary Abdle Comendius was a native of Chemos and staunch Loyalist of the Emperor and the ideals of the Unification. He was betrayed unto his death alongside his Legion's first wave during the Istvaan III Atrocity, fighting valiantly in the defence of the Precentor's Palace of the Choral City against the Traitors.Azael Konenos "The Silent", also spelled Azeal Konenos - Azael was a Consul-Delegatus of the Emperor's Children during the 30th and 31st Millennia. As a mere centurion, Konenos served as Lord Commander Eidolon's second-in-command during the ground assault against the Emperor's Children Loyalists during the Isstvan III Atrocity, leading repeated attacks and sustaining multiple injuries while doing so. This included the destruction of his voice box and larynx which were later replicated by a crude augmetic as self-inflicted punishment for his failure. He would forever after be known as "the Silent." Like his master, Konenos quickly embraced the Legion's new philosophy, altering his body further to become one of the most proeminent Noise Marines. Eidolon's continued favours ensured that Konenos would eventually be promoted to the rank of Legion consul, rising in parallel within the ranks of the Kakophoni to become one of their first orchestrators. During the Horus Heresy he commanded Battlegroup Jewel Shard from his command vessel, the Avenger-class Grand Cruiser Ravisher. Following the events upon the Crone World of Iydris within the Eye of Terror, where his primarch Fulgrim achieved apotheosis as a Daemon Prince, Azael followed Eidolon into further debauchery, self-mutilation and sadism which now consumed much of the corrupted IIIrd Legion. He later took part in the harrowing of the White Scars' fleet, and in the Battle of the Kalium Gate and the Battle of Catallus, where he was offered as a sacrifice by his own Apothecary Von Kalda and was subsequently possessed by the Keeper of Secrets known as Manushya-Rakshasi. The vile Greater Daemon would go on to possess the crew of the Emperor's Children Legionaries aboard the vessel Proudheart. Manushya-Rakshasi was ultimately slain by the Primarch Jaghatai Khan.Solathen (Sergeant) - Solathen commanded Squad Nasicae during the Great Crusade and Horus Heresy eras.Raths Luastus (Decurio) (Deceased) - Decurio Raths Luastus was a Terran-borne Astartes of the IIIrd Legion and staunch Loyalist of the Emperor and believer in the cause of Unification. He served in one of his Legion's Jump Pack-equipped assault companies. Luastus was slain during the initial Istvaan III attack by a rebel Istvaani "War-singer", a Slaaneshi battle psyker.Callion Zaven (KIA) - Callion Zaven was a Terran-born veteran Legionary of the Emperor's Children Legion during the Great Crusade who fought in the earliest campaigns to reconquer the Sol System. He saw fighting on Jupiter during the early years of the Great Crusade where he was gravely wounded, before the discovery of his Primarch Fulgrim on the world of Chemos. By the time he got out of the apothecarion, his Legion had already moved on without him and he soon found himself reluctantly serving as his Legion's emissary in the Crusader Host, and would do so for many decades, until the Warmaster's betrayal was revealed at Istvaan III. With Horus' treachery revealed he was imprisoned in Khangba Marwu with the other Crusader Host Legionaries, but eventually had his sentence commuted by the Malcador the Sigillite, and was offered a place within the ranks of his Knights-Errant. He was killed aboard the Sons of Horus' flagship, Vengeful Spirit, during the failed assassination attempt on the Warmaster.Ancient Rylanor, "Ancient of Rites" (Venerable Dreadnought) - Ancient Rylanor was a venerated hero of the IIIrd Legion and its "Ancient of Rites" who was mortally wounded battling the Eldar decades before the Horus Heresy and was interred within the adamantium shell of a Dreadnought. Rylanor was only part of Fulgrim's honour guard through tradition, though he was increasingly troubled by the direction the IIIrd Legion moved in after the assault on Laeran. He traded places for the combat drop onto Istvaan III with Saul Tarvitz, who was supposed to go instead as one of the Emperor's Children Loyalists marked for betrayal and death. Rylanor fought against the Traitors during the Battle of Istvaan III but it is unknown whether he met his ultimate fate at the hands of his former brothers.Ancient Sarancos (Dreadnought) - Sarancos was a former champion of the 9th Millennial before being interred within the adamantium shell of a Contemptor Pattern Dreadnought. Sarancos was a part of Lord Commander Eidolon's Traitor command, and he is thought to have survived the battle on Istvaan III, although he became mentally unstable owing to a combination of battle damage and trauma.Ancient Thordorian (Dreadnought) - Thordorian was a Dreadnought of the Emperor's Children during the Great Crusade era.Captain Kasperos Telmar, the Radiant King - Kasperos Telmar was an Astartes of the Emperor's Children. A native of Chemos, Telmar became an accomplished member of his Legion and Captain of the 12th Company during the Great Crusade. He was part of Fulgrim's select squad of warriors to accompany him to Byzas. During the Horus Heresy, Telmar fell with the bulk of his Legion to Chaos. After the Heresy, Telmar became a twisted monstrosity of Slaanesh known as the Radiant King, leading a powerful Emperor's Children warband himself while joining Eidolon's Phoenix Conclave. In the 34th Millennium Telmar was confronted by his old subordinate Oleander Koh and Fabius Bile, who convinced him to launch an assault on Craftworld Lugganath. Telmar hoped to not only claim the craftworld for himself, but to also ascend to daemonhood. During the subsequent battle Telmar consumed a great many Spirit Stones and began to transform into a Daemon Prince. However he became surrounded by a force of Harlequins and Lugganathi Warlocks and was cut down before the transformation was completed.Excrucias - Commanding the warship Herald of Pain, Excrucias' golden-armored Emperor's Children warband sought the help of the Alpha Legion warband known as the Unsung during the Invasion of Tsadrekha against other rival Heretic Astartes warbands. Excrucias ultimately hoped to corrupt the psychic beacon on the world in the name of Slaanesh, but after his plans fell apart he grew bored and left the world.
