House Oroborn, also known by the cognomen "The Inflicted" following the end of the Horus Heresy, is a Renegade Knight house formerly of the Questor Mechanicus that repudiated its oath of loyalty to the ancient Mechanicum and the Imperium of Man during the Horus Heresy.

House History[]

House Oroborn Knight Warden

House Oroborn colour scheme as displayed by the Knight Warden Shield of Hope during the Horus Heresy.

When news of treachery perpetrated by House Oroborn reached the wider Imperium of Man, many doubted the veracity of such information, for the household once held a fierce devotion to both Imperium and Emperor. It was the Great Crusade that revived the fortunes of House Oroborn, finding the household engaged within a centuries-old war with xenos creatures and perched upon the edge of extinction. Saved from death by the armies of the Imperium, the household swore oaths of eternal servitude, their Scions taking their place upon departing expeditionary fleets even as representatives from the ancient Mechanicum rebuilt their broken world.

The true motivations behind House Oroborn's eventual betrayal will forever remain hidden, yet many speak of a malaise that gripped the Knights of House Oroborn in the years before the Drop Site Massacre of Isstvan V. In time, many of the household's Scions returned to their homeworld, gathering in great numbers as they sought to purge that which now gripped their house.

It was fear that drove their actions for, though known by few outside House Oroborn, the affliction that had fallen upon the household was predicted by an ancient prophecy foretold in ages past, telling of a time of woe where House Oroborn would cease to be. Though such beliefs were opposed by the Imperial Truth, it appeared superstition held firm and House Oroborn lent every effort to avoid their supposed fate as more Scions returned bearing signs of sickness.

Fearful of retribution by the wider Imperium, House Oroborn turned inwards, hiding from their duties and the prying eyes of others. It was then agents of the Warmaster Horus approached House Oroborn, offering them salvation if they would but swear new oaths of fealty to the Warmaster above all.

The fate of House Oroborn was not revealed for many standard years. When they took to the field of battle once more, they did so beside the Warmaster, turning against the Imperium in their desperation for survival.

Tragically, their betrayal did nothing but seal such a fate, for the sickness that had stricken House Oroborn only festered, corrupting all it touched. Those who had once counted House Oroborn as their allies wept to see the defilement of its once-proud Knights, for what strode beside the Warmaster resembled little of what had once been, consumed by fear and suffering until only husks remained.

Notable Campaigns[]

  • Defence of Ryza (012.M31) - Amongst the echelons of the Cult Mechanicus, Ryza stood second only to Mars in power and prominence by the end of the Great Crusade. Located within the Ultima Segmentum, its position was secured by its raw manufacturing power and its tactical location that, since Ryza first forged treaties with the Imperium, served to fuel the reach of the Great Crusade eastwards across the galaxy. Above all else, Ryza possessed unparalleled expertise in the engineering and production of plasma technology. Though the war had ravaged much of the surrounding segmentum, Ryza had remained free of taint and conflict despite, or perhaps because of, the power it wielded. Yet its growing power had not gone unnoticed and, when time came for the Warmaster Horus to assault the Segmentum Solar, he moved to enforce his will upon those who had escaped notice and might yet threaten his flanks as he marched upon the cradle of Humanity. The resurgent might of Ryza proved too powerful an enclave to ignore, for it served as a waystation for Imperial forces and, left unchecked, might yet unite resistance if the absence of the Warmaster's allies allowed his foes to rally. It fell to Yuritus Omicron, fabricator-locum of Estaban VII, to conquer Ryza. In accordance with the Warmaster's wishes, Omicron assembled the might of the Legio Magna and the Legio Vulturum, promises of vast riches awaiting their patrons should their aid bring success. With them came a decad of Titans from the Legio Mortis, their presence demanded by the Warmaster to ensure victory. In all, nearly 140 Titans were assembled, their gathered might a portent of doom for the world of Ryza. These Titan Legions were not to walk alone, for the Knight houses of Morbidia and Oroborn had been amassed alongside them. With them came vast hosts of Mechanicum Taghmata, supported by a menagerie of twisted creations given life by the minds of their Dark Mechanicum masters. So gathered, the Traitor fleet departed from the fringes of the Beta-Garmon system where they had gathered for the Ryza system, intent upon conquest.
    • Ruins of Prosperity (012.M31) - No longer embroiled in conflict with the Legio Crucius, the Legio Vulturum marched west upon the southern continent of Ryza, scattering the gathered might of the Legio Osedax before them as fresh reinforcements flowed from the recently captured Conveyance Terminus Nine-Omega, the Titans of the Legio Mortis amongst them. Across the Sea of Reclamation, it fell to Legio Magna to pursue the fleeing Warmongers. To this end, the Flaming Skulls, supported by companies of tanks and the Knights of House Oroborn, descended upon the forge city of Prosperity, sweeping aside any in their way. Prosperity was a vital cog in the production of materiel and plasma reactors, the latter destined to power both Titans and vessels. Though ostensibly a city turned towards manufacture, Prosperity was both a centre of industry and a fortress constructed to withstand assault, the strength of its walls tested many times during the Age of Strife. As to the city of Prosperity itself, both Loyalist and Traitor deemed the city too important to risk raining wanton destruction down upon it and it was before the walls of Prosperity that the Loyalists gathered, meeting the Traitors as they marched across the barren plains of Ryza. Though Legio Magna managed to breach the formidable defences of the city, the Loyalists made them pay for every step the god-engines took into the city. Before Prosperity, the barren plain lay wreathed in smoke, its expanse littered with broken Titans and the tens of thousands of lesser troops crushed underfoot as the god-engines gave battle. As both sides regrouped, the Traitors plotted their next moves. Though many amongst the Legio urged a fresh assault, wishing to sate their bloodlust in glorious battle, their demands were overruled by Fabricator-Locum Omicron who bade them wait but a single night. As the sun set on Prosperity, the Loyalists arrayed themselves before its walls once more, awaiting the renewed assault they believed all but inevitable. In place of this they were met, however, by a gathering storm as the sky wept blood from blackened clouds. Within the city, debased cultists gathered in secret covens and enacted foul rituals that stirred the unnatural meteorological event into greater frenzy. Soon, rivers of blood flowed through Prosperity's streets, sickening all they touched with unnatural swiftness, while tainted winds battered the city, driving its populace mad as they fell upon each other in torment. At the apex of madness, as the city screamed its woes to the heavens, a great otherworldly howl rent the night, torn from the throat of a creature ancient and terrible. In an instant, every machine across Prosperity fell silent, plunging all into darkness. None outside the city moved, fearful of venturing within lest they be drawn into an ambush. Prosperity was abandoned to its fate.
  • Battle of Beta-Garmon, "The Titandeath" (006-013.M31) - House Oroborn took part in the long and savage Beta-Garmon campaign, which included hundreds of war zones across dozens of worlds. During this conflict, House Oroborn provided Knight support to the Legio Mortis. Even before the greater armies of the Warmaster Horus reached the star cluster, the battle lines had long since been drawn, and fighting had been going on for many Terran years. It was a cauldron of battle that would consume millions of lives before its end and see the demise of entire Titan Legions, earning this campaign the dire moniker of the "Titandeath." The Beta-Garmon Cluster, also known as the gateway to the throneworld of Terra, was the last hurdle that the Warmaster Horus' forces had to overcome before they reached the Imperium's capital world. Heavily fortified by the Loyalists, Beta-Garmon would become one of the greatest and bloodiest battles of the Horus Heresy, as well as one of the longest-lasting.

Notable Knights[]

  • Shield of Hope (Knight Warden) - This Knight Warden, depicted above, was active with House Oroborn during the Horus Heresy.
  • Guardian of Duty (Cerastus Knight Lancer) - The ranks of House Oroborn included few Cerastus Knights, even before the revelations of their defection to the Traitors' cause. When the household emerged from its self-imposed seclusion on its homeworld of Irra, the few Cerastus Knights it maintained showed considerable decay, stippled with rust and sluggish in movements. Guardian of Duty, depicted below on the muster fields of Irra circa 007.M31, represented the most minimal of changes wrought upon the household, with more extreme examples involving a seemingly endless stream of ichor flowing from the armour joints. Guardian of Duty was to fall during the battle for the Paradise World of Vizagor IV, reportedly leading a solitary, suicidal charge directly at the Loyalist guns as its companion Knights fled the battlefield.

House Allies[]

Traitor Titan Legios[]

House Strength[]

Records indicate that before House Oroborn withdrew from the Great Crusade and isolated itself upon its homeworld, its numbers approached 200 operational Knight armours, marking them as a Secundus-grade house. On the battlefield, House Oroborn favoured the widespread deployment of Questoris Knights in varying patterns, relying on the tactical prowess of its Seneschals to direct the appropriate banners to counter enemy tactics.

The Knight house is also noted to have contained a greater than average number of Knights Porphyrion within its ranks; in extended conflicts, House Oroborn would secure landing zones and establish firebases around them with its Acastus Knights. From there, Questoris Knight banners would range further afield, striking at key strategic targets before withdrawing back to protected strongholds.

House Colours[]

Pre-Heresy[]

The colours of House Oroborn were once grey and green before the onset of the Horus Heresy.

Post-Heresy[]

Though few outside the household knew the true impetus that drove House Oroborn to teachery, evidence of Chaos corruption was clear upon their forms when the house reemerged alongside the forces of the Warmaster during the Horus Heresy. Every Knight armour of House Oroborn displayed signs of solar decades of decay, with many of their armours coated in rust and sluggish in movements, while others leaked noxious fluids from the joints, each drop corroding anything it touched.

Perhaps the most tragic sign of corruption were the scattered vox fragments Imperial forces received when attempts were made to communicate with the Scions of House Oroborn, the endless cries of agony hinting at the dark fate that had befallen the household.

House Arms[]

The arms of House Oroborn is reminiscent of Old Earth's now-extinct oceanic creature, the Moray eel, which are set into a reverse 'S' shape; one head facing downwards and the other upwards, the Eye of Horus prominently displayed and centred above it, proudly declaring the Renegade Knight house's allegiance to the Warmaster. The Moray eel symbol represents House Oroborn's capacity to withstand and survive any hardship.
