The Legio Damicium ("Unbroken Lords") was a Traitor Titan Legion in the service of the Dark Mechanicum. It hailed from the Forge World of Urdesh located in the sector of space called the Belt of Iron within the Segmentum Pacificus.

Little is known of the Legio's early history save it was a sorely depleted Titan Legion by the opening years of the Horus Heresy, and was forced to rely on Mars or other beneficient Forge Worlds to charitably provide additional Titans to replace its losses.

Envious of other, more prosperous Titan Legions, the Legio Damicium soon became an envious and spiteful Legio. It willingly sided with the Traitors' cause during the Horus Heresy in the campaign known as the Cataclysm of Iron, bringing its wrath down upon more prosperous Loyalist Titan Legions.

At the conclusion of this bloody conflict, the Legio Damicium was effectively wiped out by the Loyalist forces during the Censure of Urdesh, and the Forge World was given over to the Legio Ignatum for the remainder of the Heresy, to stand sentinel over the devastated world and to punish any who would dare raise a hand against the Emperor.

Legion History[]

Little is known of the early history of the Legio Damicium, other than that it was created during the tumultuous era known as the Age of Strife to defend their home Forge World of Urdesh from the predations of xenos raiders and other threats.

By the time the Explorator fleets of Mars rediscovered this long-lost colony of the Omnissiah during the Great Crusade, much knowledge had been lost during the previous millennia, including Urdesh's ability to replenish the depleted number of god-engines of the Legio Damicium. No reason for such a loss is reported within the Forge World's archives; manufacturing logs indicate that the last Legio Damicium Titan to walk from the forge-fanes of Urdesh, a Warlord Battle Titan bearing the name Somnium Ultimus, was constructed nearly a standard millennium before the arrival of the Great Crusade to the Forge World.

No further god-engines are recorded to have been born upon Urdesh and, with each passing solar decade, the ranks of the Legio Damicium dwindled, xenos invasion and pirate raids taking their toll upon the Titan Legion.

However, this planet proved to be of great interest to the Imperium's cause, for it still possessed the knowledge required to produce vast numbers of arms for the forces of the Imperial Army. The world accepted Imperial Compliance and peacefully assimilated into the Imperium proper, after being offered a chance to replenish the numbers of the Legio Damicium.

During this time, the Unbroken Lords were a depleted Titan Legion unable to replenish their numbers without aid sent from Mars or other beneficent Forge Worlds. By the time Urdesh would be brought into the Imperial fold, the vast majority of Legio Damicium Titans bore names that alluded to the gradual march to extinction the Legio was suffering. This ritual continued even after fresh supplies of god-engines were gifted to the Legio Damicium, for the Titan Legion still lacked the knowledge necessary to construct its own Titans; to its princeps, this was delaying the inevitable rather than being a cure for their woes.

Sitting as it did on the border between the Segmentum Pacificus and Segmentum Solar, Urdesh was quickly brought into the Imperial fold, contacted by Mechanicum Explorator fleets dispatched in the vanguard of the Great Crusade. Of particular interest to the Imperium's dignitaries was Urdesh's capacity to produce vast numbers of arms and war machines frequently utilised by the Imperial Army.

When delegates from Mars first noted the dilapidated state of the Legio Damicium -- numbering as it did by that time less than 30 god-engines, many of which were battered by warfare and held together by patchwork repairs -- an offer of supply was extended to Urdesh. The Martian Mechanicum were quick to capitalise on the magi of Urdesh's desire to swell the numbers of their Titan Legion, offering the Forge World regular shipments of newly manufactured Titans in return for their loyalty, an offer that was eagerly accepted.

Mars saw Urdesh as a perfect vessel through which they could expand their power within the Segmentum Pacificus and expended much effort in securing the loyalty of the Forge World. In return for dedication to the Imperium, oaths of fealty to Mars, and the considerable prowess of its forge-fanes, Urdesh would receive the patronage of the Red Plant and regular shipments of newly forged god-engines to replenish the decaying strength of the Legio Damicium.

For the ruling bodies of Urdesh, who had already observed the marshalled strength of the Legio Mortis, such an offer proved irrefutable.

In the solar decades that followed, the promises of Mars were kept and the strength of the Legio Damicium grew to numbers not seen since the Forge World's founding, a circumstance which led the Titan Legion to bestow the name of "Unbroken Lords" upon itself. Despite this, discontent grew amongst the Titan Legion's ranks due to the refusal of Mars and other notable Forge Worlds to supply the knowledge necessary for Urdesh to construct its own god-engines, knowledge its tech-wrights desperately wished for.

After a solar decade of rebuilding, the Legio Damicium proved capable of fielding dozens of Titans where only a handful had stood previously. Relying purely on external support to replenish casualties lost on the battlefields of the Great Crusade, the servants of Urdesh regularly found themselves bowing and scraping to other Mechanicum enclaves. Failure to do so resulted in delayed shipments or a reduced number of god-engines, depriving the Legio Damicium of its promised Titans. Though such circumstances were held up as accidents that were subsequently corrected, the reliance Urdesh had on others to maintain its Titan Legion became increasingly intolerable.

Their reliance upon others bred envy within the hearts of the Legio Damicium's princeps, who often looked upon more prosperous Titan Legions as weak, for they did not stand upon the precipice of extinction.

Those of the Legio Damicium were aware that the continued existence of their Legio was determined by reliance on the generosity of others, leading many amongst their number to nurture bitterness towards more prominent Titan Legions.

Though possessing a Titan Legion, Urdesh represented only a minor force within the Belt of Iron when compared to most Forge Worlds of similar size. This deficiency in military might can be largely attributed to the reliance of the Legio Damicium on external support, with petitions for access to the knowledge necessary for the production of their own Titans repeatedly refused by their allies within the Belt of Iron.

Horus Heresy[]

The desire of Urdesh to maintain the numbers of the Legio Damicium no doubt proved instrumental in driving the Forge World into the hands of the treacherous Fabricator-General Kelbor-Hal when rebellion swept across the galaxy.

In the years before the outbreak of the Horus Heresy, increased shipments between Mars and Urdesh were recorded, dispatched on personal order of the fabricator-general. Alongside this, schematics denied to more illustrious Mechanicum enclaves were provided to Urdesh, including rare Leman Russ patterns which cemented the Forge World as the primary supplier of Imperial Army forces operating within the Segmentum Pacificus.

These gifts no doubt secured the allegiance of Urdesh for the Warmaster Horus, cultivating an image that those who served him would further reap the fruits of knowledge. When the treachery of Horus was revealed and the Red Planet fell into schism, Urdesh had already begun mobilising its forge-fanes for all-out war.

The true allegiance of Urdesh was not to be revealed until the Cataclysm of Iron began in earnest, yet the Forge World did not sit idle during the opening years of the Horus Heresy. Utlising their position on the border of the Segmentum Solar numerous clandestine tithe shipments bearing no identifying marks were apprehended ferrying materiel shipments into the heartlands of the Imperium, intended for hidden cells loyal to the Warmaster.

Urdesh also helped aid the Traitor Dark Mechanicum in establishing small cells of saboteurs that worked tirelessly to undermine the defences of the Imperium in anticipation of a time when the Warmaster would make his final move upon Terra. Suspicion quickly fell upon Urdesh, for many of the weapons bore marks similar to those displayed by its forge-wrights, yet only circumstantial evidence of this existed.

With much of the Imperium's fighting force occupied by more pressing threats, Urdesh was left to simmer, viewed as only a minor threat that could be dealt with in time. The god-engines of the Legio Damicium were to walk openly against the Emperor during the Cataclysm of Iron, focusing their wrath on those Loyalist Forge Worlds who had denied them the knowledge to construct god-engines, eager to plunder their archives for the prosperity of Urdesh.

In retribution Malcador the Sigillite, the acting Regent of Terra, dispatched a force of the Legio Ignatum, and together with a large force of fellow Loyalists within the Belt of Iron, purged the upstart Forge World during the final stages of the conflict known as the Cataclysm of Iron, effectively wiping out the Legio Damacium.

Notable Campaigns[]

  • Cataclysm of Iron (010-015.M31) - Across border sectors of the Segmentum Tempestus and the Segmentum Pacificus are located numerous lesser Forge Worlds known collectively as the "Belt of Iron." After the sundering of the Imperium, many declared for the Traitor cause, including the Legio Damicius, at the engineering of the treacherous fabricator-general of Mars, while others remained loyal to Terra or sought to remain as aloof as possible from the conflict. Strife and tentative conflict between these once-aligned worlds erupted into full-scale war in 010.M31, pitching the Traitor Mars-aligned Forge Worlds of Incunabula, Urdesh, Valia-Maximal and Kalibrax against the forces of the Loyalist worlds of Graia, Arl'yeth and Atar-Median, while Arachnis and Jerulas Station both fell into civil war. The resulting conflict, which later became known as the "Cataclysm of Iron," saw the forge lords, their armies and allied Titan Legions and Knight houses turn on each other in protracted warfare, with scores of Human-inhabited worlds in the region suffering as they became the battlegrounds upon which they fought.
    • Invasion of Ny'Drinah (302.010-552.010.M31) - Several hundred vessels, bearing the livery of both the Traitor Forge Worlds of Urdesh and Kalibrax, emerged from the Warp within the Paradonal'ny System, obliterating its defence stations with minimal losses and laying claim to the fleet anchorage. Soon after, astropaths across the Belt of Iron passed word of a widespread message, dispatched from unknown origins, calling for those worlds that had turned aside from the Omnissiah and His blessed representatives in favour of distant idols shrouded in falsehood. Acting upon preordained strategies, the Traitor Forge Worlds moved to lay claim to the valuable worlds of the Ny'Drinah sub-sector. The subsequent conquest of the sub-sector proved swift. Having secured a base of operations through their capture of the Paradonal'ny System, the Traitor fleet moved to seize their secondary targets. The core of the Traitor force consisted of Titans drawn from both the Legio Damicium and the Legio Kulisaetai, of which varying strength estimates placed between 25 and 70 Traitor god-engines committed to the conquest and whose considerable might far outstripped the defenders scattered across the Ny'Drinah sub-sector. Notably, the Traitor assault coincided with the commencement of the negotiation cycle during which the next solar decade of industrial supply was allocated amongst worlds within the Belt of Iron. This timing was no doubt meant to exploit laws which ensured that only a token force from each petitioning Forge World was allowed entry to the sub-sector, lest accusations of external pressure influencing the negotiations be levied against the process. In accordance with such an edict, less than a decad of Loyalist Titans, consisting of a mixture of Legio Atarus, Legio Venator, and Legio Astraman god-engines, stood within the sub-sector when the Traitors began their invasion and represented the sole force capable of besting an assault led by a Titan Legion. Facing a Traitor force capable of assaulting several worlds at once, the Loyalist Titans were quick to accept the inability of their numbers to defend the entire sub-sector and redeployed to the Xiloci'ny System, mustering to defend the sub-sector's capital world and await relief from allies further afield.
    • Conquest of Xiloci II (010.M31) - In the solar weeks following the fall of the Paradonal'ny System, the Traitors secured their hold upon the Ny'Drinah sub-sector, seizing control of four further systems before attempting to conquer the Hive World of Xiloci II. Here, the Traitor advance stalled, their Titan Legions contested by the considerable defences of the hive cities and the valiant retaliation of the vastly outnumbered Loyalist Titans. In an effort to break the developing stalemate, those worlds captured by the Traitors were turned towards fuelling the conquest of Xiloci II; the flow of supplies from conquered Mining Worlds was funnelled inwards, increasing the construction of materiel to the Traitor fleets within the sub-sector, while those population centres deemed "non-essential" to the continued operation of the war effort were processed into vast legions of mindless warriors augmented by profane technology which were thrown against the Loyalist defences to sap morale and drain resources. By 552.010.M31, only the Xiloci'ny and Uridoci'ny Systems remained defiant in the face of invasion, with their worlds dispatching frequent calls for aid.
    • Devastation of Yanzar IV (706.010.M31) - The first sign of relief for the defenders of the Ny'Drinah sub-sector was seen when a probing fleet from Atar-Median entered the Yanazar'ny System intent upon securing a beachhead within the sub-sector. With them came two maniples of Legio Venator Titans dispatched from Arachnus, these reinforcements sent as a sign of good faith to the Imperium. Such an act was no doubt motivated by missives of the Imperial Household having expressed concern towards the Forge World's cessation of weapon production intended for the Legio Custodes. Official reports note the dwindling shipments dispatched from the Forge World in the years following the events at the Isstvan system, no doubt hampered by the escalating tension amongst the political factions of Arachnus. This complement of Legio Venator Titans was to be the first of several Iron Spider maniples committed to the unfolding conflict within the sub-sector. The first target of the Loyalists' ire was the Mining World of Yanazar IV, a frigid planet notable for possessing significant concentrations of monazite and bastnäsite deposits beneath the surface, garrisoned by a detachment of Legio Laniaskara Titans dispatched from Valia-Maximal. Under the cover of an orbital bombardment, the Iron Spiders, led by Sub-Princeps Jandolla Altreax, descended to the surface and marched upon the entrenched Impalers Titans who guarded the sole strip of mining quarries that had survived the first invasion. As battle was joined, the Iron Spiders upon the ground were alerted of a Traitor fleet having entered the system and moved to engage the Loyalist fleet. Outnumbered in orbit, the Loyalist fleet was quickly driven off and denied the means to extract their allies on the surface. The final reports note that the initial assault by the Iron Spiders proved successful, with the Loyalists regaining control of the quarries before finding themselves trapped upon the planet and faced with a new wave of landers, bearing the livery of the Legio Damicium, descending upon Yanazar IV.
    • Assault upon the Paradonal Fleet Anchorage (874.010.M31) - The flames of insurrection were ignited upon the Paradonal fleet anchorage, culminating in the destruction of a Legio Damicium coffin ship housing four Warlord-class Titans, when the rebels seized control of several defence stations. Extensive damage was subsequently recorded at the eastern docking bays of the fleet anchorage when wreckage from the ship's destruction impacted with the station, rendering them unusable and in need of extensive repair.
    • Censure of Urdesh (149.012-856.012.M31) - The fall of the Ny'Drinah sub-sector secured a nexus of industry that, though severely damaged, proved sufficient enough to facilitate the rapid refitting of the Loyalist Titan Legions in preparation for the next stage of conquest. Although numerous conflicts raged across the Belt of Iron, the Loyalists set their sights upon the Traitor-held Forge Worlds of Urdesh and Arachnus. The assault upon Urdesh was not solely motivated by the desire to punish the Traitors, for messages from Terra itself had reached Graia calling for the censure of the planet for its efforts in ferrying supplies to the Segmentum Solar. The force dispatched by Graia in answer to these calls included over 40 Legio Astraman god-engines and 60 Knights of House Moritain within their number, yet those upon Terra dared not risk the failure of such an important mission. To this end, assistance was sent both in the form of martial strength, with Terra dispatching an octad of Legio Ignatum god-engines, redeployed from the outer sphere of defences across the Segmentum Solar, to Urdesh and relating broadcast codes, gathered by agents of Malcador the Sigillite scattered throughout the galaxy, that masked the Loyalist approach as a fleet under service to the Warmaster Horus rather than sworn to Graia. En masse, the Loyalist landing crafts descended upon the world, directed to landing zones across the surface of the Forge World. Having inadvertently invited their foe onto their world, the ruling caste of Urdesh gathered to greet the representatives of the Warmaster, flanked by a token guard drawn from Legio Damicium. Their attempts at hospitality were met with death, Morning Stars Titans standing proud before the Traitors as the landing vessel lamps lowered and, with a single devastating salvo, eradicated the upper echelons of Udresh's leadership. Across the Forge World, similar scenes played out and in quick succession a series of landing zones had been secured by the Loyalists, allowing further reinforcements to be ferried to the surface. The complete subjugation of Urdesh proved far more troublesome. With Urdesh deprived of much of their leadership, the resistance faced by the Loyalists proved uncoordinated yet ferocious, for the people of Urdesh had forever held back those seeking their destruction. The opening months of war saw the battered Legio Damicium, their numbers depleted by the Cataclysm of Iron combined with the lack of engine shipments following the blockade of the Red Planet, punish the Loyalists for their audacity, holding back the numerically superior Legio Astraman. Within the Ferrum Bastion, a vast abandoned quarry long exhausted of ore, a pack of Unbroken Lords Warhound Titans utilised its tunnels to ambush Loyalist forces, forcing solar weeks of delay as the Legio Astraman hunted them down. At the Siege of Draunheim, a month-long assault upon the forge city, seven Legio Astraman Titans were felled by the handful of Legio Damicium Warlords, the Gloria Victoria, an ancient Warmonger-class Emperor Titan, amongst them. With the Traitors contesting every advance the Loyalists made, the forces of Graia paid for each step in blood, the invasion slowly advancing until, six solar months after the death of Urdesh's leaders, the promised reinforcements from the Segmentum Solar arrived in the form of the ancient and honoured Legio Ignatum Titan Legion. In recognition of their status as one of the Triad Ferrum Morgulus, the original three Titan Legions of Mars, they were given command of every battlefield they strode upon. Alone or in pairs, the Legio Ignatum Titans joined the different fronts across Urdesh, guiding the unfolding conflict and lending both their vast experience and the fury of their own Titans to ensure victory. The forge city of Urdessec proved to be the location of the Traitors' last stand with the remnants of the Legio Damicium upon Urdesh, 11 in number and each one bearing the scars of war, standing guard over the last stronghold of Traitor strength. Were the resulting battle fought for more noble purpose in the glorious age of the Great Crusade, the names of those Unbroken Lords Titans who fell in the defence of Urdessec would forever be celebrated within the annals of glory not damned to ignominy. Against thrice their number, the Unbroken Lords held their ground, each claiming at least one foe before the city of Urdessec was reduced to rubble, never to be rebuilt. As censure for their crimes against the Imperium, the largest forge cities of Urdesh were laid waste by massed Titan fire, its knowledge banks purged of any technology the Loyalist Mechanicum deemed Urdesh unworthy of. Soon, the battered industry of the Forge World was turned towards supplying Loyalist forces, operated by fresh numbers of displaced tech-priests now part of the newly-formed Adeptus Mechanicus. By order of the Regent of Terra, the Legio Ignatum was left to stand guard over Urdesh and its holdings and given authority to punish any who dared rise once more against the Emperor.

Legion Combat Doctrine[]

Legio Damicium princeps were trained to endure pain that would drive others to the edge of insanity, a trait that proved useful in the thick of battle.

Many of the Legio's princeps were ruthless, believing nothing should stand in their way of victory, pushing themselves and their god-engines beyond all reasonable limits.

In battle, this Legio's princeps accepted that death was inevitable and would fight on to the bitter end, seizing a small measure of victory in their deaths. They would march on, not out of a sense of duty but of a spiteful need to deny their foe any measure of glory.

Legion Specific Wargear[]

  • Secondary Plating - Though the Unbroken Lords still valued the majesty of their god-engines, those of the Legio Damicium were not averse to brutalising their form by adding additional armour plating to increase their efficiency in war.

Notable Titans[]

  • Somnium Ultimus (Warlord-class Titan) - By the time the Great Crusade reached the world of Urdesh, much of the Forge World had lost its knowledge and STC patterns needed to produce additional god-engines. No reason for such a loss is reported within the Forge World's archives; manufacturing logs indicate that the last Legio Damicium Titan to walk from the forge-fanes of Urdesh, a Warlord Battle Titan bearing the name Somnium Ultimus, was constructed nearly a millennium before the arrival of the Great Crusade to the Forge World.
  • Wounded Monarch (Warlord-class Titan) - The Wounded Monarch was a Warlord Titan that fought during the Great Crusade and Horus Heresy. Its most notable engagement occurred during the Cataclysm of Iron. This Titan was nearly destroyed on three separate occasions and left for dead, only for both it and its princeps to rise again, seemingly from the dead, to stride the battlefields once more. The Legio Damicium placed great pride in their ability to stand against odds others might deem insurmountable. This behaviour stemmed largely from the fact that the Unbroken Lords relied upon the technological generosity of Mars to replenish their numbers. The Wounded Monarch, depicted above mustering upon Urdesh during the closing years of the Great Crusade, was named for its history of surviving damage initially thought unrepairable. The skull marks upon its shoulder armour relate the number of times an enemy seemingly destroyed this Warlord Titan, only for both it and its princeps to survive and rise again later to unleash its anger upon the foes of Urdesh once more.
  • Precipice of Ruination (Reaver-class Titan) - By the time Urdesh was brought into the Imperial fold, the vast majority of Legio Damicium Titans bore names that alluded to the gradual march to extinction the Legio was suffering. This ritual continued even after fresh supplies of god-engines were gifted to the Legio Damicium, for the Titan Legion still lacked the knowledge necessary to construct its own Titans; to its princeps, this was delaying the inevitable rather than being a cure for their woes. Precipice of Ruination, depicted below, was one of the first newer god-engines the Legio Damicium received following first contact with the Imperium, its name chosen as an implication that without direct control of the supply of Titans, the Unbroken Lords were but a single act of misfortune away from ruin.

Notable Personnel[]

No notable personnel listed in current Imperial records.

Legion Strength[]

Throughout the Great Crusade, the total number of operational god-engines within the Legio Damicium ranged from 50-85, marking it as a Tertius-grade Legio, with its serving demi-legio replenished by shipments dispatched from other Forge Worlds at the behest of Mars. These numbers were spread evenly amongst the three mainstay Warhound, Reaver and Warlord classes of Titans, with rarer patterns such as the Warbringer Nemesis being confined to a handful at their most plentiful.

To reduce war losses, the Legio Damicium invested heavily in the development of secondary layers of armour plating that enhanced the survivability of its god-engines; bitter about the denial of knowledge to Urdesh, the Titan Legion refused to share such developments with others of its ilk.

This Titan Legion's limited numbers encouraged the development of dedicated Taghmata support units that represented a blending of ancient Mechanicum doctrine with Imperial Army tactics. The composition of these forces, self-labelled as "Tempest Throngs," were reminiscent of the Solar Auxilia in both skill and armament, combining armoured companies with infantry well-versed in operating alongside Titans on the field of battle.

By the onset of the Horus Heresy, the Tempest Throngs had cultivated a reputation for great skill on the field of battle, often eclipsing that of the Legio Damicium itself.

Legion Appearance[]

Legion Colours[]

Legio Damicium Reaver Titan

Legio Damicium Reaver-class Titan Precipice of Ruination at the time of the Horus Heresy.

The colours of the Legio Damicium were primarily purple, with bone shoulder pauldrons, livery shields and head, trimmed in silver.

As the Legio Damicium placed great pride in their ability to stand against odds others might deem insurmountable, many of their god-engines displayed an ability for surviving damage initially thought unrepairable. Skull marks upon their shoulder armour related the number of times an enemy left an Unbroken Lords Titan for dead, only for both it and its princeps to survive and rise again years later to unleash its anger upon the foes of Urdesh once more.

Legion Badge[]

The badge of the Legio Damicium takes the form of a purple spectral skull with a mysterious rune on its forehead, centred upon a field of bone on their livery shields, and a field of yellow on their honour banners.
