The Wars for Armageddon

The Forge-World

Armageddon was, before the wars made it something else, a forge-world of the Armageddon Sector — one of perhaps two dozen comparable manufactorum planets in the Segmentum Solar whose industrial output kept the wider Imperial Guard supplied with the matériel of war. Its position made it strategically critical in ways that the planet's own population did not fully appreciate: Armageddon sat on the warp corridor connecting the Segmentum Solar to the Eastern Fringe, which meant that any force seeking to push from the eastern outer rim toward Terra would have to cross or bypass it. The planet's hive cities — Acheron, Tartarus, Infernus, Volcanus, Death Mire, Hades, Helsreach — were each manufactorum centres in their own right, populated by tens of millions, governed by an Imperial planetary administration that had been left largely alone by the wider Adeptus Terra for the simple reason that Armageddon's output was reliable and its taxes were paid. The planet was, in plain Imperial terms, an asset that the Imperium needed and that the Imperium accordingly did not interfere with.

The population were ash-tough. Armageddon's ecology, dominated by ash-wastes between hive cities and a small number of sealed habitation domes elsewhere, raised a population that lived hard, worked hard, fought when conscripted, and asked little of the wider Imperium beyond protection of the hive walls. The Armageddon Steel Legion — the Imperial Guard regiments raised from these hive cities — were considered, by Munitorum staff colleges, one of the finest tank-and-infantry combined-arms formations available to the late-millennium Imperium. They had served on a dozen fronts before any of the Armageddon Wars made the planet famous. They would serve on the Armageddon Wars too, and would lose more than half their pre-war strength across the three engagements.

The planet's defenders did not initially understand that they would be fighting one of the longest sustained military histories of the Forty-First Millennium. They thought they were defending a forge-world. They were correct, in the narrow sense. The forge-world they were defending was about to become the test case for whether the Imperium could hold a sub-sector capital against three completely different categories of catastrophic enemy across six centuries.

First War: The Daemonic Hour (444.M41)

The First War for Armageddon was, in Imperial historical terms, the one the Imperium tried hardest to forget. It began in 444.M41 with a Chaos incursion of a kind that the Imperium had not had to face on this scale since the Heresy. The incursion was led — physically led, in the form of a manifested presence that the Imperial commanders on site could actually see and that the Grey Knights would eventually be required to physically expel — by Angron, the traitor primarch of the World Eaters, who by 444.M41 had been a Daemon Prince of Khorne for nearly four millennia. Angron's host was approximately a quarter of a million Khornate daemons and the surviving World Eaters warband formations that had been retained from his Heresy command, augmented by lesser daemonic auxiliaries summoned through Warp-rifts the Imperium has never been able to fully reconstruct.

The Imperial defence was, by every honest assessment, inadequate. The Steel Legion regiments resident on the planet engaged the daemonic host on the surface and were broken within weeks. The Imperial Navy contingent assigned to the system fought a void engagement against Chaos vessels and was reduced to two ships within a month. The planet itself was being overrun. The Imperial Cardinal Astra of Armageddon broadcast an Astropathic call for help that was, by the standards of the period, theologically unprecedented in its directness; he did not request reinforcements, he requested Daemonhunters.

The Grey Knights came. Approximately three hundred Astartes of the Chamber Militant of the Ordo Malleus translated into the Armageddon system within six weeks of the call, supported by Inquisitorial assets and a small Sisters of Silence detachment. They fought Angron's host directly. They suffered casualties at rates that the Chamber Militant has not formally published. They eventually banished Angron from realspace through a coordinated daemonic exorcism that required the personal presence of seven Grey Knights Grandmasters, the Ordo Malleus's most senior Inquisitor-Lord, and the deployment of relic-grade silver psyk-out weaponry on a scale that the Imperium normally reserves for engagements of theological consequence to the wider Forty-First-Millennium balance.

When Angron was banished, the wider daemonic host collapsed into the realspace residue that the Imperium calls daemon-corpse. The Steel Legion survivors and the Imperial Navy remnants conducted ground clearance for the following eight months. The Cardinal Astra who had broadcast the call survived the engagement and was, in the immediate aftermath, declared a saint of the Ecclesiarchy for his role in summoning the Grey Knights. He was also, less publicly, mind-wiped by the Inquisition. So were the surviving Steel Legion soldiers. So was every Astra Telepathica operator who had handled the original distress call. So was every member of the planetary administration who had observed any part of the Grey Knights' work. The mind-wipes were conducted on the rationale that the Imperium could not allow widespread knowledge of how close the planet had come to falling, of what banishing a Daemon Prince had actually required, or of how routinely the Grey Knights deployed when the situation reached this threshold.

The result was that, by the closing decades of the M41, fewer than fifty people in the Imperium knew the First War for Armageddon had been a daemonic engagement. The vast majority of Imperial historians treated 444.M41 as a Chaos-cult uprising that the Astra Militarum suppressed. Sebastian Yarrick, who would later command the defence of the Second War, did not know about the First War until he was personally briefed by an Ordo Malleus Inquisitor late in his career. By that point, the Second War was already in his past, and the briefing was less about preparing him than about asking him to keep silent. He did.

We are not asking for reinforcements. We are asking for Daemonhunters.

The Half-Millennium Recovery (444-941.M41)

The five centuries between the First War and the Second War were, for Armageddon, a period of slow and grim reconstruction. The planet had lost approximately twenty percent of its pre-war population to the daemonic engagement and to the Grey Knights' subsequent purge of any survivor judged to have been corrupted by exposure to Khornate manifestation. The Steel Legion regiments raised after the War were rebuilt from scratch, drawing recruits from the surviving hive cities under emergency conscription that the Munitorum maintained for two generations. The manufactorum complexes that had been destroyed in the daemonic phase were rebuilt under Adeptus Mechanicus supervision, with new schematics that incorporated lessons the Mechanicus refused to articulate in writing but that significantly hardened the planet's industrial infrastructure against the kind of phenomena that had nearly toppled it.

The cultural memory of the First War was, by Inquisitorial design, mostly absent. The mind-wipes had been thorough. The historical records had been censored. The Cardinal Astra who had been declared a saint was venerated as a saint by an Ecclesiarchal cult that did not know what he had done to deserve sainthood and that filled the gap with myths of more conventional Imperial heroism. Armageddon, in cultural terms, remembered itself as a planet that had suffered a Chaos uprising and recovered. The deeper trauma was institutionally suppressed and personally forgotten by every survivor.

Sebastian Yarrick was born in the 800s of M41, on Mordant, a hive-world several systems coreward of Armageddon. He served his early career in the Astra Militarum's Mordant regiments, took his Commissar commission in his thirties, and rose through the Commissariat by a combination of front-line competence and the kind of refusal to die under pressure that the Commissariat institutional culture both required and routinely punished. He was assigned to Armageddon in the 930s.M41, as the threat assessments for the Armageddon Sector began to indicate that something was moving in the outer void. Ork raiding had been increasing for two decades. Imperial Navy patrols had been reporting larger and larger green-skin formations near the sector's outer rim. Yarrick took the assignment, by his own private later admission, because he expected it to be the engagement of his career. He was correct.

By 940.M41, Yarrick was the senior Commissar attached to the Steel Legion command structure on Armageddon. He had been raising defensive readiness across the hive cities for a decade. He had personally inspected the orbital defence platforms, the hive city air filtration systems (which would prove load-bearing in the eventual engagement), and the conscription rolls of every hive on the planet. He had argued, in dispatches that the Munitorum had filed under *Unproven*, that an Ork invasion of unprecedented scale was approaching. He had also argued — though never in writing — that the Imperium's response would be inadequate. He was correct on both counts.

Second War: Ghazghkull Rises (941.M41)

The Second War for Armageddon began in 941.M41 with the arrival, in the outer Armageddon system, of an Ork WAAAGH! larger than any previous green-skin engagement in Imperial historical memory. The WAAAGH! was led by Ghazghkull Mag Uruk Thraka, a Goff Warboss who had been quietly consolidating his power across the eastern Imperial fringe for the preceding two decades and who, by the time he committed to Armageddon, had welded approximately forty separate Ork clans into a single coherent force under his command. Ghazghkull was a prophet-warlord — a category of Ork that the Imperium had encountered only twice before and that emerged when an Ork of sufficient psychic strength began to receive direct guidance from the Ork gods Gork and Mork. The Imperium did not understand the theological mechanics. The Imperium understood the operational consequences: Ghazghkull's WAAAGH! moved with a coherence and strategic patience that ordinary Ork campaigns did not.

The orbital phase of the Second War lasted four months. The Imperial Navy contingent, despite Yarrick's preparation, was outnumbered approximately twelve to one and was reduced from twenty-eight capital ships to nine over the engagement's first three months. The fourth month was a holding action; the Imperial Navy reinforcement that the sector command had requested in the opening weeks was still six months away, and the Navy commander on site, Lord Admiral Theodorus, made the assessment that orbital control was lost and that further engagement would only feed the Ork supply lines without changing the outcome. He withdrew to escort the civilian evacuation that Yarrick had been quietly organising for the preceding month. The withdrawal was disputed within Imperial command. Yarrick supported it.

Ghazghkull's surface invasion began on the eighty-first day of the engagement. The Orks landed in landers that ranged from purpose-built assault craft to literal asteroids hurled into the atmosphere from orbiting hulks. Hive cities began to fall within the first week. Volcanus was overrun on day six. Death Mire was overrun on day eleven. Tartarus held for eighteen days before falling. The pattern of the engagement, by the end of the first month, was clear: the Orks were going to take every outer hive and concentrate on the inner industrial belt, where Ghazghkull intended to make whatever the WAAAGH! was for. The Imperium did not yet understand what that was. Yarrick did not understand either. He concentrated on the engagement he could see.

The Battle of Hades Hive, in the engagement's fourth month, was the turning point. Hades Hive was the third-largest hive on Armageddon and the centre of the Steel Legion's regimental command structure. Ghazghkull committed his second-tier Warboss, Ugulhard, to take it; the operation was meant to demonstrate that the inner hives could not hold and that the wider Imperial defence should accept terms. The Imperium did not accept terms. Yarrick, personally present at Hades Hive command, refused to authorise the withdrawal that the Steel Legion's regimental commanders had recommended. He stayed in the command bunker through the four days that Hades Hive was contested. He directed the defence from there. He took a krak grenade hit to his left arm in the third day's engagement that severed the arm cleanly at the shoulder. He continued to direct the defence. On the fourth day, when Ugulhard personally led the Ork assault on the command bunker, Yarrick met him at the bunker entrance. The engagement was brief. Yarrick killed Ugulhard with the krak grenade he had been holding since the previous engagement. He then, with the Steel Legion medics' assistance, attached Ugulhard's recently-orphaned power klaw to the stump of his own left arm. He used the klaw, with field-medical augmentation, for the remainder of the engagement.

The Hades Hive defence held. The Orks broke. The Imperial counterattack — the relief fleet had finally arrived in orbit, several months later than projected — broke the WAAAGH! over the following six months. Ghazghkull withdrew from Armageddon, leaving behind the largest mass of Ork dead the Imperium had ever counted in a single engagement. He did not, however, surrender. He retreated with a coherent rump WAAAGH! and immediately began rebuilding.

The Old One

After the Second War, Sebastian Yarrick became something the Imperium had not previously had an institutional category for. He had taken a power klaw off an Ork Warboss, attached it to his own body, and used it for the remainder of the engagement. The Steel Legion medics who had performed the field surgery had not removed the klaw afterwards. By the time the relief fleet's medical staff examined him post-engagement, the klaw had integrated with his remaining shoulder tissue in ways that the Apothecarion staff did not have the time or theological authority to fully un-do. Yarrick chose to keep it. The Commissariat approved. The klaw became, over the subsequent decades, his identifying feature.

The Orks called him the Old One. The naming was not a generic Ork honorific; in the linguistic logic of Ork culture, the Old One was a specific title given only to a human who had killed an Ork Warboss in single combat and taken the Warboss's signature weapon, then continued to use that weapon. There had been, by Imperial xenological research, only three previous Old Ones in recorded Ork history across multiple sub-sectors. The title carried weight. Orks who encountered Yarrick on the post-war Armageddon — there were several Ork raiding parties operating on the planet during the reconstruction years, and Yarrick personally led the engagement against them — would, in some cases, refuse to engage him. They would withdraw. They would carry the word back to their warbands. By the closing decades of the post-Second-War period, the cumulative effect was that Armageddon's outer ash-wastes were notably less raided than the wider sector's threat assessment would have predicted, because Ork raiding parties had decided, individually, that Yarrick's planet was not worth the engagement.

Yarrick used this. He raided in turn. He led Steel Legion counter-raids against the Ork holdouts that had been left on Armageddon by the Second War's retreat, and he led them personally despite his rank. The Steel Legion troopers who served on these raids — by the time of the Third War, this included most of the senior Steel Legion officer corps — knew Yarrick as a commander who would walk into an engagement at the head of the formation. They followed him. They did not always survive. The Old One's reputation was, in part, built on the bodies of the Steel Legion troopers who had walked into Ork strongholds beside him, killed Orks, and not come out.

Yarrick aged slowly. The Imperium has not publicly accounted for why. He had been in his fifties at the Second War. By the late M41, when the Third War began, he was approximately a hundred and twenty. He looked, in the official photographs the Munitorum maintained, perhaps seventy. He moved like a man of forty. The klaw, by some accounts, was doing things to him that the Imperium had not catalogued. The Inquisition had examined him. The Inquisition had not reported on its findings. Yarrick continued to serve.

I am still here. I will be here when you are not.

Between the Wars

The fifty-seven years between the Second War's conclusion and the Third War's opening were, for Imperial intelligence, a period of progressive denial about what Ghazghkull was doing. The intelligence indicators were clear from the engagement's immediate aftermath: Ghazghkull had not been killed, he had withdrawn with coherent rump forces, and he had immediately begun rebuilding on a scale that suggested he intended to return. The Adeptus Astra Telepathica intercepts of Ork inter-warband communication — to the extent that Ork communication could be intercepted at all, which was limited by the absence of any conventional Ork command-and-control structure — indicated a coordination across the eastern Imperial fringe that ordinary Ork operations did not exhibit. Yarrick himself, in dispatches the Munitorum filed across the half-century, repeatedly argued that Ghazghkull was preparing a second engagement of the same or larger scale and that Armageddon should expect a return.

The Munitorum did not act on Yarrick's warnings in any substantial way. The post-Second-War garrison on Armageddon was significant but not extraordinary. The orbital defences were rebuilt to pre-Second-War standards and not beyond. The Imperial Navy's sector presence was strengthened, but the strengthening was modest relative to the threat profile that Yarrick was projecting. The reason, by the Munitorum's later internal review, was institutional: the Imperium had won the Second War, the cost had been substantial, and the institutional consensus was that Ghazghkull — whatever he was doing — could not credibly repeat the engagement on a comparable scale within a single generation. The Munitorum was wrong. Ghazghkull was working on a generational timeline. The fifty-seven years between the wars was, in the Ork commander's strategic vocabulary, the time required to build the engagement properly.

Yarrick spent the same period preparing Armageddon as well as he could without official authorisation. He inspected every Steel Legion regiment that rotated through the planet's garrison. He personally commanded a series of small-scale engagements against Ork holdouts and incoming raiding parties, treating each as a training opportunity for the next generation of Steel Legion officers. He maintained correspondence with the Imperial Fists Chapter, with the Salamanders, and with the Black Templars Crusade — three Astartes formations he had identified as institutionally willing to commit to a defensive engagement of long duration. The correspondences were not, by Imperial military standards, exceptional. They were, in retrospect, the reason the Third War's Astartes response was as fast as it was.

In 996.M41, two years before the Third War's eventual opening, Yarrick formally requested permission to retire. The request was, by every Imperial expectation, going to be approved; he had served for over a century, had been wounded multiple times in service, and had filed his retirement intentions through the proper channels. The request was approved. Yarrick did not retire. He stayed on Armageddon. When the Munitorum auditors arrived to confirm his retirement was in effect, he met them in field uniform, with the klaw on his shoulder and the bolt pistol at his hip, and informed them that he had reconsidered. They reported this up the chain. The chain, eventually, declined to dispute the reconsideration.

Third War: Ghazghkull Returns (998-999.M41)

The Third War for Armageddon opened in 998.M41 when Ghazghkull's WAAAGH! — assembled across the preceding fifty-seven years and now larger than any single Ork engagement in recorded history — translated into the Armageddon system and immediately committed to a coordinated planetary assault. The scale, this time, was such that the Imperium understood within the first week that the engagement was qualitatively different from the Second War. Where the Second War had been a large engagement that could be lost if mishandled, the Third War was an engagement that could not be won by conventional means and could be lost by any error at any point. The Imperial response was correspondingly massive: two dozen Space Marine chapters committed forces, three dozen Astra Militarum regiments arrived in successive waves, the Adeptus Mechanicus committed Legio Metalica titans, the Adepta Sororitas sent the Order of the Argent Shroud, and Inquisitorial assets ranging from Ordo Xenos analysis teams to Ordo Malleus interdiction contingents were quietly inserted at the campaign's strategic nodes.

The hive defences were distributed across the planet. Black Templars under Reclusiarch Grimaldus held Helsreach in the south, a campaign that has its own historical literature — see *The Battle of Helsreach*, this archive. Salamanders under Tu'Shan held Tartarus in the central manufactorum belt, defending what was, by the Third War, the largest single munitions output complex on the planet. Blood Angels under Dante held the southern hives that had been overrun in the Second War and that had been rebuilt in the interim under reinforced design standards. Yarrick himself, now publicly the Imperial Hero of Armageddon and operating with a level of inter-Adeptus authority that no Commissar had previously held in Imperial military doctrine, was at Acheron, the largest northern hive and the strategic anchor of the inner manufactorum belt. He coordinated, from there, the planetary defence in a manner that the Munitorum's later analysis described as occupying a category of command authority that the Imperium did not have institutional vocabulary for. He gave orders. The orders were followed.

The campaign ran for approximately ninety days of intense planetary engagement, followed by another six months of mopping-up. The Orks took several outer hives. They were thrown back from the inner industrial belt. The orbital battle, conducted primarily by Helbrecht's Black Templars Crusade fleet supported by Imperial Navy detachments under Lord Admiral Parol, was fought across the entire system at a scale that the Navy's later staff studies treated as a separate historical sub-engagement; the orbital phase has its own dedicated archival material that the Imperium maintains separately from the planetary campaign records. The Imperial counterattack broke the Ork lines on day eighty-eight. The relief was effected. The wider WAAAGH! began to fragment as Ork warbands lost their command coordination — Ghazghkull, faced with the Imperial breakthrough, withdrew rather than commit himself to a final engagement that he assessed he could not win at the strategic cost the Imperium would impose.

Ghazghkull's withdrawal was not a defeat in Ork terms. It was a strategic decision to preserve the WAAAGH!'s rump for a fourth engagement. The Imperium understood this. The Imperium did not pursue him into the void with sufficient force to deny him the regrouping space. The Imperium had, in plain operational terms, won the Third War while leaving the strategic problem intact.

Da humies died good. Next time we's bringin' more boyz.

What Armageddon Means

The Third War for Armageddon ended in 999.M41 and was followed almost immediately by the Fall of Cadia and the opening of the Cicatrix Maledictum — events covered separately in this archive. Armageddon, by the close of M41, had survived three wars. The planet that the Imperium had used as a forge-world for the Armageddon Sector was, by every honest measure, a planet substantially different from the one that had been at the start of the Three Wars: its hive cities had been rebuilt twice over, its agricultural belts were largely lost to ash-waste expansion, its civilian population was approximately a third of pre-Wars levels, and its cultural identity had reorganised around the wars to a degree that the Adepta Terra found theologically suspect but did not act to correct.

The Steel Legion, the Imperial Guard regiments raised from Armageddon, had emerged from the Three Wars as the largest single regimental designation in the Imperial Guard's Forty-First-Millennium order of battle. Steel Legion regiments served across the Imperium and were rotated, on a long-standing internal Steel Legion convention that the Munitorum had grudgingly accepted, back to Armageddon for terminal garrison duty in their veterans' final years. A Steel Legion trooper who had served twenty years on off-world fronts could expect to spend his final five years on Armageddon's ash-wastes, training the next generation of conscripts and walking the perimeters of the hives he had been recruited from. The convention had not been broken since the close of the Second War.

Yarrick's status by 999.M41 was, in Imperial terms, paradoxical. He was officially listed as Missing in Action after the Third War's final days, when he had been observed leading a counter-WAAAGH! engagement against the rump Ork formations that had been left in the northern ash-wastes after Ghazghkull's withdrawal. His body had not been recovered. His klaw had not been recovered. The Steel Legion did not, in its internal regimental traditions, list him as dead. The Steel Legion listed him as on assignment. Steel Legion troopers who had served on Armageddon long enough to develop personal contact with Yarrick — and there were many — would report, in confidence to their officers, that they had seen him on the ash-wastes during patrols. The reports were not investigated. The Ecclesiarchy, which had been quietly lobbying for Yarrick's elevation to formal sainthood for the past two centuries, treated the post-war reports as confirmation of what the Cult was already willing to believe.

Ghazghkull's status was also unresolved. He had withdrawn from Armageddon. He had not been killed. The Imperium's intelligence — to the extent that Imperial intelligence on Ork strategic intentions was reliable, which was limited — indicated that he was preparing a Fourth War. The exact preparation was opaque. The exact timeline was unknown. What was known was that Ghazghkull, in the years following the Third War, had been seen across the eastern Imperial fringe, that his rump WAAAGH! was reorganising on a scale comparable to what he had achieved between the Second and Third Wars, and that the Imperial intelligence consensus was that the Fourth War would come. It had not yet come. It was, by every Imperial expectation, going to come.

Armageddon waited. The planet had become, in the Imperial popular imagination, the place where the human and the green-skin would keep meeting forever. The Steel Legion drilled. The hive cities rebuilt. The ash-wastes were patrolled. Yarrick, whatever he was, was still there in some form. Ghazghkull, whatever he was now, was preparing his return. The Adeptus Terra accepted this as the new shape of the Imperium: that some places would not be at peace, that some wars would not end, and that Armageddon was the canonical example of the kind of engagement the Forty-First Millennium had become.

The bells of Hades Hive ring every dawn. They have not been silent since Yarrick took the klaw.
