Adeptus Custodes - Great Crusade and Horus Heresy Eras: Constantin Valdor - Constantin Valdor was the chief custodian and Captain-General of the Legio Custodes during the Unification Wars, the Great Crusade and the Horus Heresy. Just prior to the outbreak of the Horus Heresy, Valdor was charged by the Emperor to accompany the Primarch Leman Russ of the Space Wolves in bringing the Primarch Magnus the Red of the Thousand Sons to account for breaking promises he had made during the Council of Nikaea which had strictly forbidden the use of sorcery and psychic powers within the Imperium. Valdor, with a contingent of the elite Custodian Guard, fought alongside Russ and the Space Wolves during the Fall of Prospero. He and his forces were responsible for killing at least three of the greatest psykers of the Thousand Sons Legion and routing a force much more numerous than their own. He was also responsible for saving Bjorn the Fell-Handed when his arm was corrupted by the sorcerous powers of a Thousand Sons psyker. Valdor sliced Bjorn's arm off to prevent the corruption from overrunning his body. After Horus' betrayal became known to the Imperium, Valdor was present during the meetings of the Officio Assassinorum's Clade Sires and Siresses. It was Valdor who suggested that an Assassin from each Clade operate as a team to assassinate Horus, rather than act alone as was the standard mode of operation. It is said that Constantin Valdor epitomised all that it means to be one of the Adeptus Custodes. Stoic, watchful, fiercely intelligent and -- when required -- a truly inspirational leader, Valdor was a true hero of the Imperium who never once faltered in his duty. It is not recorded what became of Valdor after the Emperor's internment in the Golden Throne, but there are those who believe he serves the Emperor still...Mikaelor Cobernus - Cobernus was a Shield-Captain of the Legio Custodes during the 31st Millennium.Ra Endymion - Ra Endymion was a Tribune of the Legio Custodes during the Horus Heresy and the commander of the Custodians who fought in the Imperial War Within the Webway. He was born on Terra during the Unification Wars to Koja Zu, the Minister of the Anuatan Steppes, around the time of the Battle of Maulland Sen. Ra's mother was executed by Constantin Valdor for the high crime of stealing Terra's last remaining ocean when Ra was only four years old. He was then taken by the Legio Custodes as a potential candidate. The young boy received his name 'Ra' in honour of the ancient Gyptian sun god and eventually rose to become the leader of Squad Dynastes, who were later dubbed the Lords of Terra by the Emperor Himself. This squad was composed of twenty sons and nephews who had been taken as tributes from various defeated Terran rulers and warlords. By the opening years of the galaxy-wide conflict known as the Horus Heresy, Ra had earned eight-hundred and seventy-one names in honour of valorous deeds and was raised to the rank of Tribune. Following the Crimson King's folly, when he tried to warn the Emperor through sorcerous means, the wards placed on the Imperial Webway deep within the Imperial Palace's dungeon were breached, which allowed the legions of Chaos to encroach upon the Emperor's Palace. Five years into the war, things began to go badly for the Imperial forces, as the neverending legions of Chaos threatened to breach the sanctity of the Palace's dungeons. With the deaths of both Tribunes Kadai Vilaccan and Jasac, Ra Endymion was given sole command over the Custodians fighting the war within the Imperial Webway. When the derelict city within the webway known as Calastar (also known as the 'Impossible City') fell to the invading Daemonic hordes, the Emperor finally left the Golden Throne in order to cover the retreat of the decimated Imperial forces and to confront the Daemon Drach'nyen. In a final epic confrontation, the Daemon took the form of a Stone Epoch war-chief, the first Human to have taken another Human life, and the Neverborn impaled the Emperor, claiming that it would be His death. But the Emperor tore the Daemon, now in the form of a great Daemonic sword, from His body and with armour-boosted strength and powerful telekinetic force, He hurled it from His grip at Ra. The sword impaled the Custodian causing the Daemon to be bound within him. The sword quickly disappeared, for it was now bound within the Custodian's body, caged within Ra's flesh. The Daemon within him could not be killed, not even by the Emperor Himself, only imprisoned. As the last remaining Imperial forces retreated from the webway, the Emperor ordered Ra to run deep within the myriad tunnels of the webway as far as possible. Ra's ultimate fate is unknown.Kadai Vilaccan - Kadai Vilaccan served as a Tribune of the Legio Custodes during the Horus Heresy in the 31st Millennium. He fought and eventually died five Teran years into the fighting during the War Within the Webway only two solar weeks after the death of Tribune Jasaric.Jasaric - Jasaric, known also as Jasac, was a Tribune of the Legio Custodes during the Horus Heresy in the 31st Millennium. He had the honour of being one of the original thirty Custodians created by the Emperor of Mankind, and had fought by his liege's side since the Terran Unification Wars, and was present during the Battle of Maulland Sen. He fought and eventually died during the fighting in the Imperial Webway War. He was succeeded by Tribune Kadai Vilaccan.Helios - Helios served as a Tribune of the Legio Custodes during the Horus Heresy in the 31st Millennium. He fought and eventually died during the fighting in the War Within the Webway. He was succeeded by Tribune Jasaric.Ixion Hale - Ixion Hale served as a Tribune of the Legio Custodes during the Horus Heresy in the 31st Millennium. Hale's ultimate fate is unknown.Diocletian Coros - Diocletian Coros was a Prefect of the Hykanatoi and served as a part of the Legio Custodes during the Great Crusade and Horus Heresy in the 30th and 31st Millennia. He fought in the War Within the Webway under the command of Tribune Ra Endymion. He was charged with organising a fresh wave of Imperial forces to resist the encroaching Forces of Chaos, which included the condemned prisoners of the fallen Imperial Knight House Vyridion, who would aid the beleaguered Imperial forces at Calastar just as the Chaos hordes began to overrun it. During this battle, Diocletian fought at the sides of both Ra Endymion and the Emperor Himself, and eventually battled his way back to Terra and escaped the confines of the Imperial extension into the Webway just before the Emperor sealed the portal, effectively ending the War Within the Webway. Following the battle, the Emperor began to show Diocleitan visions of both His and Terra's past, much as he had once done with Ra. This could be an indication that Diocletian was raised to the status of Tribune following Ra's disappearance into the Webway. Diocletian's ultimate fate is unknown, though he was later the author of the tome known as The Master of Mankind, a description of Coros' interactions with the Emperor that would still be available to the Adeptus Custodes over 10,000 standard years later.Aquillion - Aquillion served as the Occuli Imperator, the "Eyes of the Emperor," the Custodian who was assigned to watch over the Primarch Lorgar and his Word Bearers Legion after they were found to have violated the Emperor's trust during the Great Crusade by spreading their belief that the Emperor was a God to newly conquered Human worlds. Aquillion and a team of four other Custodians (Vendatha, Sythran, Nirllus and Kalhin) were assigned to the Word Bearers Legion after that Legion's humiliation on the world of Khur and the destruction of that planet's capital city of Monarchia by the Ultramarines Legion on the order of the Emperor. Aquillion used a two-handed Power Sword in combat rather than the standard Guardian Spear. Aquillion and his four-man-team were all eventually slain by the Word Bearers so that they could not inform the Emperor of Lorgar's betrayal. The leader of the Daemon-possessed Gal Vorbak, Argel Tal, decapitated Aquillion by biting his head off.Zhanmadao Navenar - Zhanmadao Navenar sreved as a Prefect of the Tharanatoi of the Legio Custodes during the Great Crusade and Horus Heresy eras in the 30th and early 31st Millennia. Navenar's ultimate fate is unknown.Mikaelor Cobernus - Mikaelor Cobernus served as a Shield-Captain of the Legio Custodes during the Great Crusade and Horus Heresy eras in the 30th and early 31st Millennia. Cobernus' ultimate fate is unknown.Honoris - Honoris served as a Shield-Captain of the Legio Custodes during the Great Crusade and Horus Heresy eras in the 30th and early 31st Millennia. Honoris' ultimate fate is unknown.Kalhin - Kalhin was one of the four other Custodians assigned to serve under the command of Aquillion to watch over Lorgar and the Word Bearers. While attempting to kill the traitor Cyrene Valantion, Kalhin was shot down by Incaradine, the mechanical Conqueror Primus of the 9th Maniple of the Carthage Cohort of the Legio Cybernetica.Nirallus - Nirallus was one of the four other Custodians assigned to serve under the command of Aquillion to watch over Lorgar and the Word Bearers. Amongst his fellow Custodes and the warriors of the Word Bearers, Nirallus was considered the "swordmaster" for his skill with his Custodian Spear. He used this skill to slay Malnor, one of the strongest of the Daemon-possessed Gal Vorbak, but was torn apart seconds later by two other members of this warrior elite of the Word Bearers Legion.Sythran - Sythran was one of the four other Custodians assigned to serve under the command of Aquillion to watch over the Primarch Lorgar and the Word Bearers Legion. He was part of the elite Squad Dynastes, called the Lords of Terra by the Emperor Himself, which comprised twenty souls, each one a scion of an extinct royal Terran bloodline, taken as tribute in conquest during the Unification Wars and inducted into the Ten Thousand. Before leaving Terra to watch over the Word Bearers Legion for 50 standard years as part of the XVII Legion's punishment for violating the Imperial Truth during the Great Crusade, Sythran swore an oath that he would not speak again until he set foot on Terra once more with this duty complete. He kept this promise until the moment of his death at the hands of the Gal Vorbak, when he mocked the Word Bearers' Chaplain Xaphen just after killing him for his betrayal of the Emperor.Vendatha - Vendatha was one of the four other Custodians assigned to serve under the command of Aquillion to watch over Lorgar and the Word Bearers. Vendatha was used as the tenth sacrifice to summon Ingethel, the Daemonic Emissary of the Chaos Gods.Zerin - Zerin was a participant in a "Blood Game" alongside Amon, Haedo and Brokur. Out of the four, Zerin did the worst, as he did not even make it into Imperial Territory before he was caught by his fellow Custodians in the city of Irkutsk.Iacus - Iacus was one of the 15 Custodes sent to watch over the Word Bearers Legion who was not assigned to watch over the Primarch Lorgar with Aquillion. Iacus and his fellow Custodes watched over First Captain Kor Phaeron and First Chaplain Erebus instead. Before the Word Bearers' treachery came to light, Iacus and all his Custodes had fallen in battle alongside the Word Bearers, never knowing of their betrayal.Arcatus Vindix Centurio - When on Terra the Emperor Himself imprinted the genetic knowledge of the primarch-programme onto Corvus Corax, he also ordered a squad of his very own bodyguards to accompany the Primarch of the XIX Legion back to Deliverance to protect the sensitive knowledge. Although the knowledge imprinted into Corax's mind would slowly fade, the Custodes would continue their Emperor-given task to protect and watch over the Primarch of the Raven Guard. As leader of this new bodyguard and the man whose task it had been to watch over the Raven Guard during their stay in the Imperial Palace, Arcatus Vindix soon became a figure of influence within Corax's war council, as the Raven Lord enjoyed debating with the leader of the Custodians when not on the front lines or even in the heat of battle. Whereas Corax always marvelled at Horus' temerity to declare war on the Imperium, Arcatus had a quite different point of view -- Horus would never have turned Traitor if he hadn't been sure from the beginning that he would win. Alongside the ever-active Raven Guard, Arcatus and his brothers saw much combat, participating in the Raid on Kapel-5642A and the Day of Vengeance on Carandiru. Once the Raven Guard had sufficiently recovered from its losses in the Drop Site Massacre, Arcatus was given leave to depart and return to Terra. Accompanied by the Imperial Fists of Captain Noriz aboard their Strike Cruiser Wrathful Vanguard, Arcatus and his men reached the Sol System in the wake of the Battle of Pluto and where challenged by picket ships of Battlefleet Solar. Upon hearing a preagreed codeword, Arcatus and his men immediately turned their weapons upon one particular member of their party, the former Raven Guard Librarian Balsar Khutturi who had broken the Edict of Nikaea on the orders of Corax. Captain Noriz and every Imperial Fist on the Wrathful Vanguard chose to assist Khutturi, a fellow Space Marine alongside whom they had fought for several Terran years. While the Custodians tried not to harm the Imperial Fists, Captain Noriz's obstinacy in aiding his friend led to his unfortunate demise at the edge of Arcatus' Guardian Spear. With the blood of his friend still fresh on the Custodes' blade, Balsar Khutturi launched himself at Arcatus but ultimately refrained from using his psychic powers. Knowing he could not beat the Custodes, the Raven Guard surrendered to their will, thus passing the test set for him by Malcador the Sigilite who wished to recruit him as one of his Knight-Errants.Brokur - Brokur took part in a "Blood Game" alongside Amon, Haedo and Zerin. Brokur emerged as the runner-up in the contest as he made it to The Hegemon before he was caught. Valdor had not expected anyone to get closer to the Imperial Palace than Brokur, but Amon succeeded in infiltrating the Palace itself.Saturnalia Princeps Carthagina - Saturnalia was a member of the Legio Custodes during the Horus Heresy era. He was assigned to the Psi-Hunter Team charged with the task of capturing the Outcast Dead -- the surviving members of a small Legiones Astartes honour guard known as the Crusader Host that was stationed on Terra. The fugitive Astartes were members of the Traitor Legions that had sided with Horus in his rebellion against the Emperor during the Horus Heresy. They had been imprisoned in the maximum security prison known as The Vault since they could no longer be trusted, but they managed to stage a break-out and escape. Saturnalia became part of the hunt team led by the Seer Hunter Yasu Nagasena to track down the Outcast Dead in an attempt to regain his honour after letting the Outcast Dead take his prisoner, the Astropath Kai Zulane. During the final battle with the Outcast Dead in the Temple of Woe, Saturnalia managed to kill Subha, a World Eaters Berserker. Subbha's twin, Asubha, attacked him and drove a Custodian Guardian Spear through Saturnalia's head, just as Saturnalia managed to stab Asubha in the heart with his own Guardian Spear.Haedo Emankon - Haedo Emankon took part in one of the many "Blood Games" alongside Amon, Zerin and Brokur. Of the four participants in the contest, Haedo was the third most successful, as he made it to Cebu City before he was caught. Haedo Emankon was later charged by Constantin Valdor to gather incriminating evidence on a member of the government of unified Terra who was suspected of treason against the Emperor alongside Amon Tauromachian.Khorarinn - Khorarinn was a member of the Legio Custodes during the Great Crusade and Horus Heresy eras. Following the Istvaan III Atrocity, Khorarinn was assigned to work alongside the Knight-Errant, Agentia Primus Nathaniel Garro, a former Battle-Captain of the traitorous Death Guard in determining the loyalty of a ragtag refugee fleet that sought sanctuary within the Segmentum Solar. They were led by the loyalist World Eaters Captain Macer Varren. Khorarinn was highly suspicious of Varren's motives as well as Garro, as they were both formerly members of known Traitor Legions. Further tension was built up between Garro and the Custodian when the latter threatened to kill Tylos Rubio should he utilise his psychic powers in direct violation of the Emperor's Decree Absolute, as laid down during the Council of Nikaea. Ironically, he showed respect towards the White Scars Captain Hakeem, an unexpected member of the refugee fleet, who turned out to be a traitor who was loyal to the Warmaster. Hakeem and his traitorous White Scars would eventually go on to kill Khorarinn as those whom the Custodian accused of disloyalty attempted to save his life.Amon Tauromachian - Amon Tauromachian was a member of the first circle of the Legio Custodes during the Great Crusade and Horus Heresy in the 30th and 31st Millennia. Amon was present during the Triumph of Ullanor, where Horus Lupercal was invested by the Emperor with the title of Imperial Warmaster and command over all the Imperium's armed forces and overseeing the final stages of the Great Crusade. When he was manning a checkpoint alongside a fellow Custodian, Haedo Venator, as well as seven Null-Maidens of the Silent Sisterhood, Primarch Magnus the Red was impressed by Amon's stoicism and dedication and predicted that there were great things ahead for him. Many years before the start of the Heresy, Amon was present at the Council of Nikaea to watch over the trial of Magnus the Red for his use of sorcery. Whilst protecting Kasper Hawser, a skjald of the Space Wolves, Amon was attacked by a minion of Chaos in the disguise of a Thousand Sons Space Marine, but managed to survive the encounter thanks to the efforts of the Astartes of the Space Wolves. Amon was later charged with protecting the Emperor when Terra began the process of fortification to withstand the coming assault by the Warmaster Horus and his Traitor Legions. After news of Horus' betrayal reached Terra, Amon was tasked with taking part in the "Blood Games", a rite all Custodians endured and one which set them against the formidable defences of the Imperial Palace in the hope of improving the Custodians' defence of the Emperor through the exposure of flaws in his protection. Following his success in the "Blood Games", Amon Tauromachian and a fellow Custodian Haedo Emankon were sent on a dangerous mission by Constantin Valdor, the Chief Custodian, to gather incriminating evidence on a member of the government of unified Terra, who was suspected of treason against the Emperor but who was in actuality a double-agent working for the Imperium. Amon would go on to be regarded as one of the greatest members of the Legio Custodes. His ultimate fate is unknown.Sumant Giri Phalguni Tirtha - Tirtha was a Veteran Custodian, whose name was said to bear at least seventy-six awarded titles. He was one of the gaolers at the high security Imperial prison on Terra known as The Vault. It was not known how Tirtha had come to Khangba Marwu. He bore no obvious injury and was in prime physical condition, but rumour said he had once questioned an order from the Captain-General, Constantin Valdor. Tirtha was charged with the duty of guarding an extremely dangerous group of prisoners known as the Outcast Dead, the remnants of the Astartes honour guard known as the Crusader Host that was stationed on Terra whose parent Legions had turned Traitor and sided with Horus. Tirtha was killed during the Outcast Dead's successful escape attempt from The Vault, when Atharva of the Thousand Sons took control of an elite soldier with a Plasma Gun and made him shoot Tirtha in the stomach.Uttam Luna Hesh Udar - During the Horus Heresy era Udar was the lead gaoler of the subterranean high security prison built to detain those individuals deemed hostile to the Emperor and isolated from the world above. Built beneath the Himalayan peak known as Rakaposhi, only the most senior Custodians bothered to use its original name, Khangba Marwu, and for those condemned to its cells, who would never again see the light of day, it had an altogether more prosaic name. They knew it simply as The Vault. Udar was removed from the fighting ranks of the Legio Custodes after being exposed to an Ork bacteriological pathogen, whose aftereffects greatly reduced his reflexive response times to a level below the minimum required for frontline service amongst the Custodians. A proud man, he took his removal from the front lines hard, but eventually adapted and took to his new role as a gaoler at The Vault with the same determination and attention to detail that had seen him come the closest to the full infiltration of the Imperial Palace in the Blood Games until his peer Amon Tauromachian Leng bested him. During his tenure, Udar was charged with watching the last remnants of The Outcast Dead -- a small group of Astartes warriors drawn from the Traitor Legions that were the last of the Crusader Host, an honour guard of Space Marines comprised of representatives from each of the 18 Space Marine Legions that served on a rotational basis within the Imperial City outside the Imperial Palace on Terra. Udar met his ultimate fate when The Outcast Dead engineered a successful escape attempt. Udar was slain when he confronted one of the berserker World Eaters Astartes in close combat. The berserker in question, Sergeant Tagore, ripped out a section of Udar's spine through his chest, just as Tagore had promised he would during his confinement.Sagittaras (Sagittarus Malacque) - Sagittarus was one of the first thirty Custodians created by the hand of the Emperor of Mankind and served alongside his liege as His personal Honour Guard during the Terran Wars of Unification. Choleric and wild, he was the first Custodian to be wounded unto death, and interred within the sarcophagus of the Contemptor Pattern Dreadnought as a part of the Legio Custodes Moritoi.Vetiranio Shapura - Shapura, once a Prefect and senior officer of the Legio Custodes, was a figure of some legend within the annals of the Great Crusade. His was the distinction of being perhaps the third or fourth of the Custodian Guard (records differ) ever to be interned within the sarcophagus of a Dreadnought. The glory of his fall was that it occurred in the act of protecting the Emperor Himself from direct bodily harm during a perfidious attack in which the Imperial flagship, the Bucephalus, was successfully boarded by the forces of the xenos Rykogene with the aim of slaying the Master of Mankind. It was an attack for which the species would ultimately pay for by its extinction. The honour of the Ferrum Aquila, seen on the shield his Dreadnought-form carries, attests to Vettranio Shapura's sacrifice still.Abram Hasrubal - Moritoi Excelcis Abram Hasrubal was one of several Legio Custodes Dreadnoughts who served in the forces dubbed the 'Talons of the Emperor' as a part of the Censure Host sent to Prospero, envisioned as part of a reserve in case of emergency. As matters transpired, the Dreadnoughts of the Moritoi were utilised as part of the Custodes' first wave, dispersed through mixed units of Custodian Guard and the Silent Sisterhood to strengthen them and contend with Thousand Sons heavy units when encountered. Hasrubal was one such, attached to the splinter command of Prefect Tern Lanais in the assault on the pyramid of Lhis'Ta on the northern edge of the great plaza of Tizca.Primarus - Primarus was a Custodian who had been interred within the adamantium, cybernetic sarcophagus of an unknown model of Dreadnought, to continue fighting on behalf of the Emperor during the Great Crusade and Horus Heresy eras. His ultimate fate is unknown.Senitorus - Senitorus was a Custodian who had been interred within the adamantium, cybernetic sarcophagus of an unknown model of Dreadnought, to continue fighting on behalf of the Emperor during the Great Crusade and Horus Heresy eras. His ultimate fate is unknown.Gathas - Gathas was a member of the elite Squad Dynastes, called the "Lords of Terra" by the Emperor Himself which comprised twenty souls, each one a scion of an extinct royal Terran bloodline, taken as tribute in conquest during the Unification Wars and inducted into the Ten Thousand. He fought and eventually died during the fighting in the Imperial Webway War under the command of Tribune Ra Endymion.Mycorian - Mycorian was part of elite Squad Dynastes, called the  "Lords of Terra" by the Emperor Himself which comprised twenty souls, each one a scion of an extinct royal Terran bloodline, taken as tribute in conquest during the Unification Wars and inducted into the Ten Thousand. He fought and eventually died during the fighting in the Imperial Webway War under the command of Tribune Ra Endymion.Juhaza - Juhaza was part of elite Squad Dynastes, called the  "Lords of Terra" by the Emperor Himself which comprised twenty souls, each one a scion of an extinct royal Terran bloodline, taken as tribute in conquest during the Unification Wars and inducted into the Ten Thousand. He fought and was badly injured during the fighting in the Imperial Webway War under the command of Tribune Ra Endymion. Juhaza's ultimate fate is unknown.Solon - Solon was part of elite Squad Dynastes, called the  "Lords of Terra" by the Emperor Himself which comprised twenty souls, each one a scion of an extinct royal Terran bloodline, taken as tribute in conquest during the Unification Wars and inducted into the Ten Thousand. He fought in the Imperial Webway War under the command of Tribune Ra Endymion. Solon's ultimate fate is unknown.
