Hathor Maat was the Captain of the 3rd Fellowship of the Thousand Sons Space Marine Legion during the latter days of the Great Crusade and the beginning of the Horus Heresy in the late 30th and early 31st Millennia. He also served as the Magister Templi of the XV Legion's Pavoni Cult. Hathor Maat was present during the Burning of Prospero, when the Space Wolves Legion, accompanied by elements of the Legio Custodes and Sisters of Silence, were sanctioned by the Emperor of Mankind to punish the Thousand Sons Primarch Magnus the Red for his blatant violations of the Imperial Decree Absolute rendered during the Council of Nikaea forbidding the use of psychic powers and the pursuit of sorcery. He was one of the few survivors of the massacre who escaped when their mortally wounded Primarch Magnus the Red teleported them to the Planet of the Sorcerers within the Eye of Terror. He would later join Ahzek Ahriman's secret cabal and take part in casting the Rubric of Ahriman in order to stop the mutational "flesh-change" that ravaged the remainder of their Legion within the Eye. Following the casting of the Rubric, Ahriman and his cabal of Chaos Sorcerers were banished by their angry Primarch. Maat's current whereabouts are unknown.
Hathor Maat was born on the world of Prospero, and joined the ranks of the XV Legion, newly renamed the Thousand Sons, after they were reunited with their lost gene-sire. He was a member of one of the earliest intakes of potential Neophytes. His early career as an Astartes is not well known, he first appeared in recorded history as being seconded to the Emperor's Children in their earliest days as they fought alongside the Luna Wolves. As Hathor Maat told it, he had caught the Phoenician's eye with his perfectly moulded features, and had fought within his sight on many an occasion. Maat's proudest possession was an Oath of Moment carved by Fulgrim, and fixed to his breastplate as he took his leave to return to Prospero. As part of their training, all Captains of a Thousand Sons Fellowship (equivalent to the Legion formation of a Chapter) undertook a secondment to another Space Marine Legion to learn its ways and further the Thousand Sons' understanding of the galaxy and pursuit of knowledge.
The Great CrusadeEdit
By the close of the Great Crusade in the early 31st Millennium, Maat had already risen to the esteemed rank of Captain of the 3rd Fellowship and served as the Magister Templi of the Pavoni Cult. The members of the Pavoni Cult tended to be the most egocentric of the known Cults within the Thousand Sons Legion, as they had developed the psychic discipline known as physiokinesis. Physiokinesis allowed the Pavoni to manipulate body chemistry and physiology within themselves as well as others, a very useful trait for a group of already superhuman warriors. Skilled practitioners of physiokinesis were able to alter their physical appearance by manipulating the physical characteristics of their facial features at will as well as making themselves immune to the harmful effects of dehydration and other physical ailments. On the field of battle, the Pavoni were able to generate lightning by unleashing the inherent bioelectricity of their own nervous systems and focus it offensively, as well as cause the hearts of enemy warriors to explode by literally boiling the blood within their veins. When using these abilities against their foes, the Pavoni had a reputation for venality and spite which bordered on the sickening. The Pavoni were also the designated healers of the XV Legion for as masters of biomancy they were capable of accelerating cellular growth and protein synthesis, which made them extraordinary medics who saved the lives of countless Astartes when even the Apothecaries could not.
Hathor Maat took part in the Imperial Compliance action of the world of Aghoru (officially codified in Imperial records as 28-16). This action was carried out by units of the Thousand Sons Legion who managed to achieve Compliance through simple diplomacy without bloodshed and was thus considered a great success. Secondary combat operations were carried out against apparent Warp denizen infestation (beings known to the local population as "Elohim") within the subterranean passages of a titanic peak that stood taller than Olympic Mons on Mars. The Thousand Sons forces were further enhanced by a small unit drawn from the Space Wolves Legion during this operation. At the height of these combat operations, the joint-Astartes forces faced off against a pair of unidentified Chaos-corrupted xenos combat walkers similar to Titans. In an incredible, awe-inspiring display of his powerful psychic abilities, the Crimson King faced off against one of the Titans alone and managed to bring it crashing down to the rocky ground far below. Weakened and severely exhausted by the effort, the remaining Titan took the opportunity to strike at Magnus with its primary lance weapon. Had it not been for the heroic efforts of his fellow Captain Phosis T'Kar erected an invisible barrier of psychic force, known as a "kine-shield", around both himself and the Primarch, they would both have been killed. But extraordinary effort nearly drained T'Kar to the point of death. Only through the careful administrations of Hathor Maat was T'Kar saved from certain death.
Ark Reach Cluster CampaignEdit
The Ark Reach Cluster had been discovered by the Word Bearers Legion's 47th Expeditionary Fleet; it was a group of binary stars occupied by a number of belligerent human planetary empires that rejected the Imperium's offer to become part of the Emperor's growing demesne. This Imperial Compliance action of the Great Crusade was carried out through the combined efforts of the Thousand Sons working in concert with elements from the Space Wolves and the Word Bearers Legions. The first four star systems fell to the Word Bearers and Space Wolves. But the fifth and sixth proved more difficult, especially on the world of Helios, the cardinal world of the Avenian Empire. The Avenians were graceful and fine-boned, their facial features sharp and angular, like the mountains in which they lived. Their bodies appeared weak and fragile, but that was a lie. Autopsies had discovered bones that were flexible and strong, and their armour was augmented with fibre-bundle muscles not dissimilar to those within Astartes Power Armour.
Ark Reach Secundus was the Imperial Cartographe designation for this world, a convenient label that began the process of assimilation before envoys were even despatched or shots fired in anger. Its people called it Heliosa, but the Imperial Army had another name for it, a name synonymous with the razor-beaked killers that were the bane of soldiers forced to assault the aerie fortresses. They called it Shrike. The Thousand Sons soon proved to be instrumental in breaking open the defences of the Ark Reach Cluster, their additional weight of force tipping the balance of war in favour of the Imperium. While the Word Bearers quelled the civilian population of outlying mountain cities, the Thousand Sons cleared a path for the Space Wolves to deliver the deathblow to the heart of the Avenian Empire. Only the settlement of Phoenix Crag remained and the world would be brought into successful Compliance.
The Primarchs had met the previous evening to discuss how best to assault Phoenix Crag, Leman Russ and Lorgar were both eager to utterly eradicate the city, though for very different reasons. Russ simply because it stood against him, Lorgar because its ignorance of the Emperor offended him. It would be hard to imagine three more different brothers: Russ with the bestial mask he thought fooled everyone with its bellicose savagery, and Lorgar with his altogether subtler mask that hid a face even Magnus could not fully discern. They had spoken long into the night, each of his brothers vying for the upper hand. Phoenix Crag would not be like the other mountain cities of Heliosa, its records destroyed, its artefacts smashed and its importance forgotten. Magnus would save the history of this isolated outpost of humanity, and reclaim its place in the grand pageant of human endeavour. This world had survived the nightmare of Old Night, and deserved no less.
The following day both the Thousand Sons and Space Wolves Legions, each lead by their prospective Primarch, assaulted the final bastion of resistance. Ahzek Ahriman's 1st Fellowship linked with Hathor Maat's 3rd in a gorge of artisans' workshops, and scout elements of the Prospero Spireguard joined them in a region of hollowed-out silo peaks. Leman Russ and his 1st Great Company had dropped directly onto the silver mountain's highest peak, extinguishing its eternal flame and toppling the symbols of rulership. The Hearthguard of the Phoenix Court valiantly opposed the surging, unstoppable force of the Space Wolves, but they had been torn to scraps and hurled from the mountaintop. The defeated Avenian kings offered terms of surrender, but Leman Russ was deaf to such pleas. He had sworn words of doom upon his Legion's Grand Annulus, and the Wolf King would never break an oath for something as trivial as mercy. The Space Wolves tore down through the mountain, an unstoppable force of nature, their blades and bolts gutting the defenders' ranks like a butcher with a fresh carcass. Nothing was left in their wake, the mountain city a work of art vandalised by thoughtless brutality and wanton savagery. Behind the warriors of Russ was only death, and before them was their next target for destruction: the Great Library of the Phoenix Crag, where Magnus the Red and Phosis T'Kar's 2nd Fellowship stood in ordered ranks. Finally, the Space Wolves rampage was halted.
Both Ahriman's and Maat's forces linked up with their fellow Battle-Brothers to assist in forming a line of defence against the battle-crazed Space Wolves. Enraged at what he perceived as his brother's betrayal, the Wolf King let forth with a howl of pure rage, cold jagged and merciless. It was the rage of a hunter's fury denied. The force of psychic might was too powerful for any normal mind, and killed many Battle-Brothers within the ranks of the Thousand Sons. This psychic shockwave killed almost every member of the Athanaean Cult in the 2nd Fellowship, and most of the Athanaeans who weren't killed outright were reduced to drooling lackwits. The Great Company of Amlodhi Skarssen charged the implacable and immovable bulwark formed by the Thousand Sons, their charge unstoppable, elemental power. Enraged by his feral brother's shortsightedness, Magnus was more than willing to kill every last Space Wolf in order to preserve the knowledge within the Phoenix Crag. For though the Thousand Sons had not started this fight, they would more than be happy to finish it. Magnus ordered Maat and the Pavoni of the 3rd Fellowship to take the Space Wolves down. The Captain of the 3rd Fellowship hammered a fist into his chest and directed his ferocious will to aiding his Battle-Brothers. Brother Hastar stood next to him as his fellow warriors of the Pavoni unleashed the full force of their bio-manipulation. Unseen currents of aetheric energy sliced into the Space Wolves, blocking neural transmitters, redirecting electrical impulses in the brain and rapidly deoxygenating the blood flowing from their lungs. The effect was instantaneous. The Space Wolves' push faltered as their bodies rebelled. Limbs spasmed, heart muscles fibrillated and warriors lost all physical autonomy, jerking like the maddened dolls of a demented puppeteer. Chief Librarian Ahriman tried to talk some sense into his gene-sire, before the situation spun out of control.
The fighting only ceased when Hastar, an Astartes of the 1st Fellowship, underwent the cursed mutational "flesh-change" during the battle. Ahriman and one of his fellow Captains fought to hold Hastar's body down, but the changes wracking his body were as apocalyptic as they were catastrophic. With the gurgle of wet meat and the crack of malformed bones, Hastar's body was suddenly upright, though any semblance of limbs was impossible to pick out in his erupting flesh. Swelling bulk and crackling energy patterns writhed across his flesh, and his screams turned to bubbling gibbers of maniacal laughter. The Thousand Sons scattered from Hastar's terrible new form, horrified and terrified in equal measure. This was their greatest fear returned to haunt them, a horror from their past long thought buried. A dreadful, wracking sickness quickly seized all the other Thousand Sons present and their innards began to rebel against their fixed shapes, their entire bodies trembling with desire for new form. A surging wave of power erupted as Magnus the Red stepped towards the hideously transformed Hastar. Unchecked energy had destroyed the warrior of the Pavoni, but it empowered Magnus.
The creature Hastar had become reached out to Magnus, as though to embrace him, and the Primarch opened his arms to receive him with forgiveness and mercy. But before the Crimson King could help his stricken son, a thunderous bang sounded and Hastar's body exploded as a single, explosive round detonated within his chest. This was one of the first ever recorded acts of violence of an Astartes killing another and the first known time a member of the Thousand Sons Legion was killed by a member of the Space Wolves Legion. Only through the timely intervention of Lorgar did the two Primarchs not come to blows. This act of calculated brutality was the first wedge to be driven between Leman Russ and Magnus the Red.
Triumph of UllanorEdit
Four solar months after the collapse of resistance on Shrike, word came that the last text of the Phoenix Crag library had been copied into the archive stacks of the Photep. A day later, the 28th Expeditionary Fleet broke orbit, and Magnus the Red gave the order to make best speed for an isolated shoal of spatial debris in the galactic east of the Ark Reach. The various shipmasters of the 28th Expedition queried the coordinates, as they were far from the calculated system jump point, but Magnus’ order was confirmed. This region of space would allow their vessels a calmer entry to the Great Ocean, and only when the fleet had reached this newly declared jump point did Magnus reveal their ultimate destination. The 28th Expedition had been summoned to the Ullanor System, and excitement spread through the fleet at the prospect of joining the war against the Greenskin. More thrilling was the prospect of joining forces with the Emperor Himself, who fought in the forefront of the Ullanor Crusade, smiting the savage foe alongside Horus Lupercal. Hopes of glory to be earned and battles to be fought were dashed, only to be replaced by awe, as it became known that the campaign was already over. The war against the Greenskins of Ullanor had been projected to last for standard years, decades even. The Emperor's summons was not in the name of war, but of victory.
The Thousand Sons were to stand with many of their brother Legions in a Great Triumph honouring the Emperor's victory, a spectacle the likes of which the galaxy would never see again. Under Magnus' expert direction, the fleet Navigators plotted a razor's course for the Ullanor System. Fourteen Space Marine Legions had answered the Emperor's summons, a 100,000 of the greatest warriors in all human history, and nine of the Primarchs were in attendance, the rest too scattered by the demands of the Crusade to reach Ullanor in time. Eight million soldiers of the Imperial Army had come, and a dizzying plethora of banners, battle flags, trophy standards and icon poles were rammed into the ground in the centre of each armed camp. They stood proud alongside thousands of armoured vehicles and hundreds of Titans of the Legio Titanicus. Towering above the mortal soldiers, the treads of the mighty battle engines were like a city of steel on the march. The Thousand Sons were amongst the last Legion forces to make planetfall. The entire continent sweltered like a blacksmith's forge, the hammer of history ready to beat the soft metal of existence into its new form. Only an event of galaxy-changing magnitude could warrant such a spectacle. Only the greatest being in the galaxy could inspire such devotion. This was to be a gathering like no other.
Horus was to be given the new honour of an Imperial title above and beyond any that had been bestowed before; a title, it could be said, that would forever carry the echo of his name. After declaring Horus as Imperial Warmaster and the new supreme commander of the Great Crusade, the Emperor, to the shock of those assembled, announced his own intention to return to Terra to pursue a secret project intended to benefit all Mankind. After more than 200 standard years of hard conflict by the early 31st Millennium, over two million human-settled worlds across the Milky Way Galaxy had been reclaimed by the Emperor in the name of the Imperium of Man. Beside Him stood the Primarch Horus, who had fought alongside the Emperor for the early part of the Great Crusade as His only rediscovered son and primary military commander, glorying in the singular attentions of his father. The long wars had forged a strong bond between them, and they were truly father and son. But now the Emperor had to consolidate His newborn Imperium, and undertake the next phase of His Grand Plan for humanity.
At this announcement there was much shock and outrage. Many of the other Primarchs did not understand why the Emperor was leaving them to fight the enemies of Mankind alone and, worse still, why Horus should be raised as the first amongst equals. The situation only grew worse when the Emperor announced that He would be creating a civilian administrative bureaucracy known as the Council of Terra that was comprised of Imperial bureaucrats and nobles to carry out the day-to-day governmental affairs of the Imperium, replacing the direct rule of the Emperor while He was engaged in his secret Imperial Webway Project. The Council of Terra would implement and administer the new galaxy-wide tax of resources and manpower called the Imperial Tithe and other matters of day-to-day law in the burgeoning Imperium of Man. The Primarchs would be relegated to a primarily military role as the Imperium's most preeminent commanders. Many of the Primarchs, including Horus, were deeply disturbed that their father would make them subject to normal men and women who had never shed blood in the establishment or expansion of the Imperium and that he would remove them from the political positions of rule to which they believed they were entitled. The Emperor had sought to create a civilian bureaucracy for the Imperium precisely because he wanted regular human beings to learn to govern themselves once more and not become beholden to a permanent, genetically-enhanced ruling class. The Chaos Gods would ultimately use the Primarchs' resentment as one of the all-too-human weaknesses they could exploit to corrupt half their number.
Council of NikaeaEdit
As the Great Crusade progressed, some of the Primarchs voiced their dissent that so-called "psyker" Astartes were allowed to exist and be a part of the Emperor's righteous Great Crusade. Rumours and condemnations began to spread about the Thousand Sons Legion amongst the other Expeditionary Fleets. The most vocal of these detractors were the Primarchs of the Death Guard, Imperial Fists and Raven Guard Legions. The majority of the Astartes of the XV Legion had been afflicted by the rampant genetic mutation within their ranks early in their existence. Those that still remained unafflicted had seen their psychic abilities increase dramatically in power level. Soon the Thousands Sons' detractors raised their objections to the Emperor Himself, calling for the XV Legion's disbandment and for the Legion to be expunged from Imperial records like the II and XI Legions.
The Emperor was also displeased by the Thousand Sons' dabblings in manipulating the corrupting powers of the Warp and later forbid the use of sorcery by either Magnus the Red or the members of his Legion after an Imperial Conclave was called on the world of Nikaea to deal with the question of psykers. When a consensus emerged among the Council of Nikaea's participants that psykers and their powers represented a potential danger to the people of the Imperium, the Emperor's edicts were that in the interest of unity, no one was to be censured for prior actions involving the use of psychic abilities. However, the future use of psychic abilities by the Imperium's military forces was banned (except the use of Astropaths, Navigators, and very strictly sanctioned and controlled psykers who were authorised to carry out Imperial business, like the Sisters of Silence). All Astartes Legion Librarians were to be disbanded, and their members returned to conventional combat duty. In effect, Magnus and the Thousand Sons were banned from practicing "sorcery" or using the psychic abilities and knowledge they so coveted.
As one of Magnus' senior Captains, Hathor Maat had the honour of escorting his Primarch to the Council of Nikaea, and stood resolutely at his Primarch's side during the Emperor's pronouncement against the further use of psychic abilities or the pursuit of forbidden knowledge in regards to the Warp. Following the Emperor's Decree Absolute, Magnus and his Thousand Sons could not depart Nikaea fast enough. The bulk of the XV Legion returned to their homeworld of Prospero, and unknown to them, events would soon transpire that would prevent them from ever leaving it again. Despite the Emperor's decree, Magnus continued his forbidden pursuit of knowledge into the arcane. Meanwhile the other Legions continued to earn glory in battle; the Emperor's Children on Laeran, the Luna Wolves on One-Forty-Twenty, the Ultramarines at Mescalor. It had been over two standard years since the Ark Reach campaign and yet the Thousand Sons sat idle while their brothers made war. The Primarch has had all his warriors buried in their cults' libraries after their return to Prospero. Magnus had been keeping a monstrous secret from his Captains while he worked feverishly and alone in his private library and the vaults beneath the Prosperine capital city of Tizca. Amon and Ankhu Anen, Guardian of the Great Library of Prospero and member of the Corvidae Cult, had shared Ahriman's knowledge that something was wrong, but even their combined power was unable to pierce the veils of the future to see what so concerned their Primarch.
Gathering the members of the Rehati within his private sanctum, Magnus revealed to his sons that he had foreseen a terrifying vision of the Warmaster Horus falling from grace and dragging the burgeoning Imperium of Man into a war more terrible than any of them could imagine -- an Age of Darkness that had been prophesied tens of thousands of standard years before by the ancient Aegyptos of Old Terra. Though he did not exactly know the means by which Horus would fall, all he could perceive from his vision is that something primordial and corrupt would take root in his soul. Magnus had foreseen that the Luna Wolves Legion would soon be making war on a moon of Davin, and the fates were conspiring to fell Horus with a weapon of dreadful sentience. In his weakened and blinded state, the enemies of all life would make their move to ensnare his warrior heart. Without the intervention of the Thousand Sons, they would succeed and split the galaxy asunder. The works that Magnus had Amon researching since the Council of Nikaea held the key to Horus Lupercal's salvation. With the help of his Fellowship Captains, Magnus projected himself across the Warp and attempt to shield his brother from his enemies. Unfortunately, the Primarch failed and Horus' soul was corrupted by the Ruinous Powers.
Burning of ProsperoEdit
When Magnus the Red learned of Horus' betrayal of the Imperium and his decision to give his loyalty to the Dark Gods, he used his own psychic abilities to get a message to the Imperial Palace on Terra by directly contacting the Emperor mind-to-mind, though this ruptured the Palace's considerable psychic defenses and killed thousands of people whose minds were unable to handle Magnus' potent psychic call. But the Emperor refused to believe that His favorite son Horus would ever betray His trust and so He assumed that it was Magnus who had been corrupted by the Chaos Gods since he was once again using the sorcerous powers that had been banned by the Council of Nikaea. Believing that Magnus sought to sow dissension in the Imperium to serve his masters in the Warp, the Emperor ordered the Space Wolves Legion to go to Prospero and bring back Magnus to Terra, so he could give account for his actions. But this was not to be, as the corrupted Warmaster Horus had intercepted the Emperor's communique with Russ' Legion and subtly manipulated their orders. Instead of just arresting the offending Primarch Magnus for his transgressions and bringing him back to the Emperor for censure and punishment for breaking his oath never to use his psychic powers again, Horus changed their orders to read that the Space Wolves were to assault the Thousand Sons' homeworld of Prospero. Magnus had psychically foreseen the Loyalist Space Marines' attack on Prospero, which was eventually carried out by the Space Wolves Legion, elements of the Emperor's Legio Custodes, and millions of Imperial Army troops, all assisted by the Sisters of Silence acting as psychic "blanks" in order to nullify the Thousand Sons' psychic abilities.
Magnus had finally understood, after his forced psychic entry into the Hall of the Golden Throne and his direct mental communication with the Emperor, that he had been manipulated by Tzeentch, with whom he had apparently unknowingly consorted with while desperately looking for a way to stop the emergence of the psychic mutations that were threatening to destroy his Legion. In an act of repentance and sacrifice, and to show his father that he and his Legion were loyal to the end, he did not warn the defenders of the planet or his Legion of the coming Imperial attack; on the contrary, he imposed a psychic veil on the planet so the Thousand Sons would have no clue of the impending assault. He also dispersed the Thousand Sons' Legion fleet far away from Prospero. He knew that Tzeentch wanted the Thousand Sons and Space Wolves to slaughter each other, and he wanted to stop these plans, even if it meant the sacrifice of his Legion and homeworld. Therefore, the Space Wolves' attack on the Thousand Sons' homeworld of Prospero came as a complete surprise. Because there was no warning, the invading fleet translated from the Warp into realspace practically on top of the planet, and quickly destroyed its orbital defences, initiating the great campaign of the Horus Heresy known as the Fall of Prospero to Imperial historians.
Establishing a beachhead in the spaceport area, the Space Wolves began slaughtering thousands of Prosperines, burning everything in sight. Yet the Thousand Sons' rank-and-file did not share Magnus' acceptance of defeat and punishment, so they took up arms against the Loyalist invaders. Despite a valiant defence, the surviving Thousand Sons were pushed back towards the Pyramid of Photep, their last refuge on Tizca. The best and bravest of the Legion, all that survived to sell their lives in sight of their Primarch, went with their First Captain towards the bronze gates that led inside. Scores of Thousand Sons died in the opening minutes of the Wolf King's attack, his fury unstoppable and his power immeasurable. Clad in the finest battle-plate and armed with a Frostblade that clove warriors in two with single strokes, his fury was that of a pack hunter who knows his brothers are with him. Though Phosis T'Kar could see no more of the hateful Sisters of Silence, he knew they were there, for his powers were weakening, bleeding from his hands like ink from a splintered quill. The Custodes slew with powerful strokes of their Guardian Spears, hewing armour and flesh with efficient strokes that hit with precisely the force required to do the job of killing.
Changing his mind about his inaction, the Crimson King reluctantly faced his brother Russ in single combat. Magnus used his powerful psychic magicks, battering Russ with fists of telekinetic force wreathed in fire and lightning. Yet, Russ was a Primarch and such powers had little effect on him save to drive him to greater fits of rage. Magnus drove his fist into Russ’ chest, the icy breastplate cracking open and shards of Ceramite stabbed into the Wolf King’s heart. In return, Russ snapped Magnus' arm back, shattering it into a thousand pieces. A blade of pure thought unsheathed from Magnus' other arm, and he drove it deep into Russ' chest through his shattered armour. The psychic blade burst from Russ' back and the Wolf King let loose with a deafening bellow of pain. A chorus from his Fenrisian Wolves added their howls to that of their master. The two enormous lupine monsters that accompanied Russ leapt upon Magnus, fastening their jaws upon his legs. Magnus slammed his fist into the black wolf's head, driving it to the ground with a strangled yelp, its skull surely shattered. With a bellow of anger, Magnus tore the white wolf from his leg with a thought and hurled it away over the heads of the army at Russ' back.
Magnus and Russ were locked in battle high above the causeway to the pyramid, the furious horror of their struggle obscured by ethereal fire and bursts of lightning. A flare of black light erupted and Russ cried out in agony. His blade lashed out blindly and struck a fateful blow against Magnus's most dreaded weapon: his eye. Magnus reeled back from the Wolf King, one hand clutched to his eye as his shattered arm crackled with regenerative energies. As broken and bloodied as Leman Russ was, he was brawler enough to seize his opportunity. He barreled into Magnus and gripped him around the waist like a wrestler, roaring as he lifted his brother's body high above his head. All eyes turned to Russ as he brought Magnus down across his knee, and the sound of the Crimson King's back breaking tore through the heart of every Astartes of the Thousand Sons. As Russ unsheathed his Frostblade Mjalnar to take the head of his defeated brother, with the last of his strength, Magnus whispered eldritch words of power and teleported his remaining sons deep into the Eye of Terror upon a world prepared for them by their new patron, the Chaos God Tzeentch.
Rubric of AhrimanEdit
Once transported to the Planet of the Sorcerers in the Eye, the Thousand Sons soon succumbed to the "gift" of their patron and true saviour from the Fall of Prospero, the Chaos God Tzeentch -- the full return of their aberrant genetic mutations, which threatened to turn all of the surviving Thousand Sons into mindless, gibbering Chaos Spawn. Appalled by the return of the dreaded mutational "flesh-change", Ahriman gathered a secret cabal of the most powerful Chaos Sorcerers within the Legion to halt the dreaded genetic curse. Hathor Maat was one of the first to join Ahriman's cabal for he feared the ruin of his flesh more keenly than anyone, suffering the nightmarish dread that one day he too would be overcome by the "flesh-change" and become less than nothing, a devolved creature with nothing left of the man he had once been. The cabal joined with Ahriman to unlesh the invocation of a powerful daemonic spell later known as the Rubric of Ahriman. The spell was successful, but its success came at a high price: those Battle-Brothers of the Legion who lacked psychic abilities were transformed into living automatons -- the Rubricae. Their bodies were reduced to dust, and their souls were forever sealed within their suits of Power Armour -- every joint magically sealed, forever trapping the souls within in a nightmare existence of living death.
The minority of Thousand Sons Astartes who did possess psychic abilities, and so did not succumb to the Rubric, soon found their psychic abilities increased to a tremendous degree by the power of the spell. The ritual also accomplished its goal, halting the dreaded mutations, both in the surviving sorcerers and their undead brethren. Magnus was enraged by Ahriman's audacious spell and what it had done to his sons, but was secretly pleased with the level of sorcerous knowledge the Legion had attained through their metamorphosis. Confronting the cabal who had carried out the Rubric, Magnus exiled Ahriman and his remaining collaborators from the Planet of the Sorcerers and ordered them to forever roam the galaxy in search of understanding and knowledge of the true meaning of Chaos, a quest that continues unto the present day. Hathor Maat's current status is unknown.
