Campaigns

The Ember Maw Campaigns were not a single war, but a crucible that forged the Onyx Dragons into the Chapter they would become. Fought across the volcanic equatorial belts of Draconia in the centuries following their founding, these campaigns were waged not against a unified enemy, but against the world itself—and the predators that ruled it.

In the early years of the Chapter, Draconia was far from secured. Vast regions of the planet remained dominated by cinder wyrms and other apex predators, while unstable volcanic activity rendered entire continents uninhabitable. The fledgling Chapter faced a choice: abandon large portions of their homeworld, or claim it through fire and blood.

They chose to hunt.

The War for Draconia

The Ember Maw Campaigns began as a series of localized operations to secure territory around Mount Cindral and the construction sites of the Ebon Spire. What followed was a centuries-long expansion into the most hostile regions of the planet.

Companies were deployed not in full strength, but in hunter cadres—small, highly mobile forces tasked with tracking and eliminating wyrm populations, stabilizing regions for human settlement, and establishing forward bastions in terrain that resisted all conventional occupation.

These were not wars of lines and fronts. They were hunts without end.

The Cinder Wyrms

The greatest threat came from the cinder wyrms themselves—colossal predators capable of burrowing through volcanic rock, surviving within magma flows, and emerging without warning to devastate entire formations. Their obsidian scales deflected standard munitions, while their sheer size and ferocity made them living siege engines.

Early encounters resulted in heavy losses. Entire squads were lost to ambushes beneath the ash, and armored units were dragged into molten fissures by creatures that could not be tracked by conventional means.

In response, the Onyx Dragons adapted.

Forging the Hunt

It was during these campaigns that the foundations of the Chapter’s doctrine were laid. Scouts and forward elements learned to identify patterns in the movement of prey. Mechanized and aerial forces were used not for sustained assault, but for rapid strikes at moments of vulnerability. Assault troops were trained to deliver decisive killing blows at close range, where even the mightiest wyrm could be brought down.

From these lessons emerged the earliest form of what would become the Kill-Hunt Principle.

Each hunt followed a pattern:

• Identify the prey

• Break its defenses

• Strike at its core

• Burn what remained

What began as survival became doctrine.

The Shaping of the Chapter

The Ember Maw Campaigns did more than secure Draconia—they defined the Onyx Dragons.

Warriors who survived these hunts were marked not only by scars, but by understanding. They learned patience in the face of overwhelming force, discipline in the use of violence, and the necessity of finishing what they began.

It was also during this era that the Trial of the Ember Maw was formalized. Aspirants were no longer tested in controlled environments, but cast directly into the same crucible that had forged the Chapter itself. To survive was to prove worth. To return with proof of the hunt was to earn a place among the Dragons.

Legacy

By the end of the campaigns, the equatorial belts of Draconia had been brought under the Chapter’s control. Settlements were established, trade routes secured, and the dominance of the cinder wyrms broken—though never entirely ended.

Even now, the Ember Maw is not truly conquered.

It is left as it was: a place of fire, ash, and predators. A reminder of what the Chapter overcame—and what it must always be prepared to face again.

To the Onyx Dragons, the Ember Maw Campaigns are not history.

They are origin.

The Siege of Kharix-Delta was a proving ground for the Onyx Dragons’ mastery of fire and endurance, a brutal campaign fought against Chaos forces entrenched within a volcanic hive complex. It was here that the 4th Company—the Iron Drakes—cemented their reputation as the Chapter’s unbreakable siege force.

Kharix-Delta was a frontier world of strategic value, its manufactoria supplying vital war materiel to nearby Imperial sectors. When it fell to a Chaos warband, the planet became a fortress of corruption. The enemy did not simply occupy the hive—they reshaped it, turning its industrial core into a layered defense of barricades, kill-zones, and daemon-infused war engines.

Initial Imperial attempts to reclaim the world failed. Guard regiments were stalled in the outer districts, unable to push into the hive’s interior without suffering catastrophic losses. Orbital bombardment proved ineffective, as the hive’s lower levels were shielded by layers of reinforced structure and corrupted energy fields.

The war demanded a different approach.

The Iron Drakes Advance

The Onyx Dragons committed the 4th Company to the siege, placing Captain Garran Volkr at the forefront of the assault. Rather than attempt a rapid breakthrough, the Iron Drakes advanced with deliberate force, turning each engagement into a controlled burn of the enemy’s defenses.

Infiltrator teams moved ahead of the main force, identifying weak points and mapping the shifting interior of the hive. Behind them came the Breath: disciplined volleys of plasma, melta, and heavy firepower that stripped away outer defenses and collapsed fortified choke points.

Then came the Claw.

Heavy Intercessors, Aggressors, and Dreadnoughts advanced into the breach, securing each section of the hive before moving forward. Every corridor was cleared, every chamber purged, every defensive position reduced to slag. The Iron Drakes did not rush. They consumed the hive one level at a time.

War in the Depths

As the siege pushed deeper, the nature of the enemy became clear. Warp-tainted constructs and mutated defenders emerged from the lower manufactoria, fighting with unnatural resilience and fury. Entire sectors of the hive had been transformed into breeding grounds for corruption, their infrastructure repurposed into engines of war.

The deeper the Iron Drakes advanced, the more the hive resisted.

Temperatures rose as reactors destabilized and molten flows breached containment. Toxic fumes choked the air. Entire sections collapsed under sustained bombardment. Yet still, the Iron Drakes advanced.

Chaplain Garrus Vorn—The Unbroken Pyre—walked the line throughout the campaign, ensuring that no warrior faltered under the strain. Flame Vigils were held between engagements, even as the siege continued around them, binding the company together through loss and endurance.

The Breaking of the Core

After months of relentless advance, the Iron Drakes reached the hive’s central manufactorium—the heart of the enemy’s control. Here, the Chaos warlord had entrenched himself within a fortress of corrupted steel and daemonic machinery.

The final assault was not swift.

Volkr committed the full strength of his company, bringing Dreadnoughts and armored assets into the confined space of the manufactorium. The battle raged through molten chambers and collapsing structures, each meter gained through disciplined fire and unyielding advance.

At the height of the fighting, Volkr himself led the breach into the warlord’s stronghold. With the relic hammer Drake’s Bite, he shattered the defenses that had resisted months of assault and brought the warlord down in a final, crushing blow.

Aftermath

With the death of its master, the Chaos presence within Kharix-Delta began to collapse. Remaining resistance was purged in systematic sweeps, and the hive was reclaimed—though at great cost.

The manufactoria were left scarred and partially ruined, their lower levels sealed and quarantined to prevent further corruption. Yet the world was saved, its production eventually restored to serve the Imperium once more.

Legacy

The Siege of Kharix-Delta stands as one of the defining campaigns of the Iron Drakes. It proved that there are foes who cannot be broken by speed or surprise—only by endurance, discipline, and the willingness to advance through fire until nothing remains.

To the Onyx Dragons, it reaffirmed a truth learned in the Ember Maw:

Some prey does not fall quickly.

It must be ground to ash.

The Shattering of Velkrax is remembered not as a campaign of armies, but as a single hunt that changed the course of the Onyx Dragons forever. It was on this day that Draconis, then a rising Captain, slew the greatest cinder wyrm ever recorded—and in doing so, claimed the mantle of destiny.

Velkrax was no ordinary predator. It was an ancient wyrm of immense size and fury, a creature that had dominated the volcanic equatorial belts of Draconia for generations. Entire regions had been rendered uninhabitable by its presence. Settlements were destroyed without warning, hunter cadres vanished without trace, and even veteran Astartes squads suffered catastrophic losses attempting to bring it down.

For decades, Velkrax was not hunted.

It was avoided.

The Marking of the Prey

Draconis was among the first to argue that this could not continue. To leave such a creature unchallenged was to accept weakness within the Chapter’s own domain. He saw Velkrax not merely as a threat, but as the apex prey—the hunt that would define the Onyx Dragons.

Gathering a small cadre rather than a full company, Draconis began a prolonged tracking effort across the ash-choked wastes. Patterns were observed. Movements were predicted. Feeding grounds and dormant cycles were mapped with painstaking precision.

This was not a war.

It was a hunt.

The Hunt Begins

When the moment came, Draconis did not commit overwhelming force. Instead, he chose precision.

The engagement began with aerial harassment, forcing Velkrax from its subterranean lair and into open terrain where its movement could be controlled. Mechanized elements struck at range, drawing its fury and guiding it toward a prepared kill zone within a fractured volcanic basin.

Even then, the creature proved nearly unstoppable.

Velkrax tore through armored vehicles, shattered Dreadnoughts, and consumed entire squads in moments. Its obsidian scales deflected heavy fire, and its sheer size turned the battlefield itself into a weapon. Lava flows erupted under its movement, and ash storms choked visibility.

The hunt was failing.

The Killing Strike

At the height of the battle, with his forces battered and the creature still unbroken, Draconis made the decision that would define him.

He closed.

Using his jump pack to navigate the chaos of fire and molten terrain, he advanced directly toward the wyrm, drawing its attention and forcing it into a moment of overextension. As Velkrax struck, Draconis evaded the killing blow and drove his glaive deep into a vulnerable joint beneath its armored scales.

The strike did not kill the beast.

It wounded it.

What followed was not a single blow, but a relentless series of precise strikes—each one calculated, each one exploiting a weakness revealed in the moment. Draconis fought not as a warrior, but as a hunter, adapting to the creature’s movements in real time.

At last, with a final thrust delivered into the creature’s core, Velkrax fell.

The ground itself shook as its body collapsed, its molten blood spilling across the basin in rivers of fire.

Aftermath

The death of Velkrax changed Draconia.

Regions once dominated by the great wyrm became accessible. Settlement expanded. The balance of predator and prey shifted, and the Onyx Dragons secured greater control over their homeworld than ever before.

But the impact was not merely physical.

From the remains of the fallen wyrm, the Chapter forged relics that would endure for generations. Its bones and scales were taken to the forges of the Ebon Spire, where they would become symbols of command and instruments of war.

From this act came Skywrath, the Wings of the First Flame.

Legacy

The Shattering of Velkrax is remembered as the moment Draconis became more than a warrior. He became the embodiment of the Chapter’s creed.

He had identified the prey.

He had broken its defenses.

He had struck its heart.

And when the battle was done, nothing remained but ash.

To the Onyx Dragons, this was not simply victory.

It was proof.

The Ashfall Reversal stands as the only recorded campaign in which the Onyx Dragons were forced to yield the field. It is not remembered for defeat—but for the lesson it burned into the Chapter’s doctrine: that not all prey can be broken by force alone.

The campaign took place upon the ash-wreathed world of Karthax V, where a Chaos warband had entrenched itself within a vast fortress complex built into a collapsed caldera. The structure was a labyrinth of reinforced bastions, subterranean chambers, and void-shielded strongpoints, its defenses layered to absorb prolonged assault.

The 4th Company—the Iron Drakes—was deployed to conduct a full siege.

The Iron Advance

Captain Garran Volkr initiated the campaign in accordance with established doctrine. Forward elements secured the outer approaches, while Devastator fire and armored support began the slow process of dismantling the fortress defenses. Rhino-borne Tactical Squads established fortified positions, gradually tightening the noose around the enemy stronghold.

For weeks, progress was steady.

Outer bastions fell. Supply lines were severed. The enemy was contained.

The fortress would break.

The Unseen Resistance

It did not.

As the Iron Drakes pushed deeper into the caldera, resistance intensified beyond expectation. Enemy forces displayed coordination that exceeded initial intelligence estimates. Defensive positions thought neutralized reactivated. Assault corridors collapsed without warning.

More troubling still, entire squads began to vanish within the lower levels of the fortress.

No distress calls.
No confirmed kills.
Only silence.

What had been assessed as a fortified position began to reveal itself as something more complex—a layered defense that adapted to the Iron Drakes’ advance.

The Collapse

The turning point came during a coordinated breach of the inner bastion.

As multiple squads advanced through newly opened corridors, the enemy triggered a cascading series of detonations and structural collapses. Entire sections of the fortress shifted, sealing off units, isolating strike teams, and cutting lines of communication.

At the same time, counterattacks erupted from unexpected vectors—enemy forces emerging from previously cleared zones and striking with precision.

The battlefield became unstable.

Controlled advance became fragmented survival.

The Decision to Withdraw

Volkr faced a choice few of his kind are ever forced to make.

Continue the assault—and risk the destruction of the company within a collapsing, hostile environment.

Or withdraw.

The order was given.

Under constant pressure and with limited visibility, the Iron Drakes executed a fighting withdrawal from the caldera. Positions were abandoned, wounded were carried or left behind where recovery was impossible, and remaining forces regrouped beyond the outer perimeter.

The fortress was not taken.

Aftermath

Karthax V was later subjected to sustained orbital bombardment, reducing the caldera complex to molten ruin. The enemy was destroyed—but not by the hand of the Iron Drakes.

Losses within the 4th Company were severe. Entire squads were listed as missing, their fate unknown. Equipment and relic wargear were lost within the depths of the fortress.

For the Onyx Dragons, the campaign was recorded not as a victory—but as a failure of understanding.

Legacy

The Ashfall Reversal reshaped the doctrine of the Iron Drakes.

No longer would siege warfare be treated as a matter of endurance alone. Greater emphasis was placed on reconnaissance, structural analysis, and the identification of hidden threats before full commitment.

The lesson was clear:

Force can break a wall.
It cannot break what it does not understand.

From that day forward, the Iron Drakes did not simply advance into fortresses.

They learned to hunt within them.

When the fires of war came to Draconia, they did not come as a trial—but as an invasion. For the first time since the Chapter’s founding, the Onyx Dragons were forced to defend not a distant world, but their own. What followed was not a campaign of conquest, but a war for the right to endure.

The threat emerged as a Waaagh! of significant strength, a Greenskin horde drawn by the constant violence and instability of Draconia itself. Ork warbands descended upon the planet in waves, their ramshackle fleets punching through orbital defenses and crashing into the volcanic equatorial regions.

To the Orks, Draconia was not hostile.

It was ideal.

The First Impact

Initial landings struck across the ash plains and fire seas, where the Orks established crude but effective strongholds amidst the chaos of the terrain. Gargants and war engines were assembled directly atop unstable ground, their presence triggering further tectonic upheaval that reshaped entire regions.

Ash-cities were overrun. Outlying settlements fell within days.

The clans did not flee.

They fought—and died—holding the line long enough for the Chapter to respond.

The Chapter Returns

The Onyx Dragons redeployed with full force.

Companies were recalled from distant campaigns, striking the Ork invasion from multiple vectors. The 2nd Company executed armored spearheads through the ash wastes, breaking massed Ork formations before they could consolidate. The 3rd Company descended from the skies, targeting command elements and disrupting the cohesion of the Waaagh!.

The 4th Company—the Iron Drakes—anchored the defense of key settlements, turning volcanic terrain into fortified kill zones. The 5th Company operated beyond the main lines, hunting warbosses and dismantling Ork leadership before it could fully organize.

This was not a single battle.

It was a world on fire.

War in the Ash

The environment itself became both weapon and hazard.

Ork machinery destabilized the already volatile crust, triggering eruptions that consumed entire formations. Lava flows cut off advances as often as they enabled them. Ash storms reduced visibility to nothing, forcing engagements at close range where brutality favored the Greenskins.

Yet the Onyx Dragons knew this world.

They adapted.

Ork advances were funneled into unstable regions. Strike forces used the terrain to isolate and destroy larger warbands. Kill zones were established where the ground itself would betray the enemy.

The hunt had come home.

The Breaking of the Waaagh!

The turning point came with the coordinated elimination of multiple Warbosses.

Through combined action between the 3rd and 5th Companies, key leaders were identified and struck in rapid succession. Without centralized command, the Waaagh! began to fracture. Ork forces turned on one another, their cohesion collapsing into isolated pockets of violence.

The 2nd Company drove into the heart of the largest remaining formation, shattering it in a final armored assault.

The invasion broke.

Aftermath

The cost was severe.

Several ash-cities were destroyed beyond recovery. Entire clans were lost. Regions of Draconia were rendered even more unstable, scarred by the scale of the conflict.

Yet the world endured.

The Ebon Spire never fell.

The Onyx Dragons remained.

Legacy

The Defense of Draconia stands as the only time the Chapter has fought a full-scale war upon its own soil. It reaffirmed not only their mastery of the hunt—but their bond to the world that forged them.

Draconia is not protected because it is safe.

It is protected because it must endure.

To the Onyx Dragons, the lesson was clear:

They do not merely wage war across the stars.

They are guardians of the fire that made them.

What began as a suspected rebellion upon the hive-world of Haxtor Prime revealed itself to be something far more insidious: a xenos infestation that had already taken root deep within the planet’s underhive. By the time Imperial authorities understood the truth, the lower levels of Haxtor Spire had become a breeding ground for a parasitic horror that threatened to consume the entire world.

Initial reports spoke of infrastructure collapse, vanishing populations, and entire hab-blocks falling silent. Arbites patrols sent to investigate did not return. Vox traffic degraded into fragmented distress signals before ceasing entirely.

The truth emerged only when survivors reached the upper hive—mutated beyond recognition, their bodies encased in chitin and their minds lost to an alien will.

This was not rebellion.

It was infestation.

The Hidden Rot

The parasite spread through the lower hive unchecked, infecting manufactorum workers, labor crews, and entire population clusters. The victims were not simply killed—they were reshaped. Flesh hardened into armor, limbs twisted into bladed appendages, and entire sectors became spawning grounds for the xenos presence.

The infestation adapted quickly, integrating itself into the hive’s infrastructure. Conveyor lines became arteries. Reactor chambers became incubation pits. Entire industrial sectors were consumed and repurposed into living nests.

Containment was impossible.

The only solution was fire.

The Iron Drakes Deploy

The Onyx Dragons committed the 4th Company—the Iron Drakes—to the cleansing.

At this stage in the Chapter’s history, the Iron Drakes were composed of Firstborn battle companies, organized along Codex lines:

Tactical Squads forming the advancing line

Devastator Squads delivering disciplined heavy fire

Assault Squads acting as breach and shock elements

Rhino and Razorback transports moving forces through secured corridors

Predator tanks and Venerable Dreadnoughts providing heavy support

Under Captain Garran Volkr, the campaign was not treated as a battle.

It was a purge.

War Beneath the Hive

The Iron Drakes entered from the upper hive, sealing access points behind them as they advanced downward. Each level was isolated, fortified, and cleared before the next descent began.

Tactical Squads advanced in disciplined formations, bolter fire cutting down lesser bioforms in controlled volleys. Devastator teams established kill-zones within manufactoria corridors, their heavy weapons reducing larger creatures before they could close.

Assault Squads were committed at critical breach points, driving into nests with flamers and chainswords, clearing the enemy at close range where the infestation was strongest.

The fighting was slow and relentless.

Every corridor had to be taken.

Every chamber burned.

Every nest destroyed.

The Living Hive

As the campaign progressed, the infestation revealed its full nature.

The hive itself began to resist.

Organic growth spread through structural supports. Passageways shifted or collapsed without warning. Entire sectors sealed themselves behind advancing forces. The Iron Drakes were no longer fighting within the hive.

They were fighting the hive.

In response, Volkr adapted. Manufactoria were converted into fortified bastions. Rhino transports were used as mobile barricades. Entire sections were deliberately collapsed to prevent encirclement.

Progress was measured in meters.

The Breaking of the Core

Weeks into the campaign, the Iron Drakes reached the lowest manufactorum levels—zones long abandoned and now completely overtaken. There, they discovered the source of the infestation:

A massive bio-organic nexus embedded within the hive’s industrial core, directing the spread of the parasite and sustaining its growth.

The final assault was conducted with full company strength.

Devastator fire stripped away outer defenses. Predator tanks, brought into the depths at great risk, unleashed sustained bombardment. Venerable Dreadnoughts advanced into the breach, their heavy weapons and adamantium frames anchoring the assault.

At the center of the nexus, Captain Volkr led the final push.

Armed with Drake’s Bite, he shattered the core structure of the infestation, collapsing the network that sustained it.

The Purge

With the destruction of the nexus, the infestation began to fail.

Without coordination, the remaining bioforms were hunted down and eliminated in systematic sweeps. Entire sectors were flooded with promethium and burned. Reactor overloads were triggered to slag irrecoverable zones.

The lower hive was not reclaimed.

It was entombed in fire.

Aftermath

Haxtor Spire was saved—but only partially.

The upper hive remained functional, though scarred by loss. Entire population sectors were gone, and the lower levels were sealed permanently. Even now, access to those depths is forbidden.

Imperial authorities declared the world secure.

The Onyx Dragons knew better.

Legacy

The Culling of Haxtor Spire stands as one of the defining Firstborn-era campaigns of the Iron Drakes. It demonstrated the strength—and the limitation—of traditional battle company doctrine against a threat that could not be broken by speed or maneuver alone.

It also marked the beginning of a shift.

Lessons learned in the depths of Haxtor would later influence the Chapter’s evolution into its Primaris-era siege doctrine, where flexibility, heavier infantry, and integrated firepower would refine what the Firstborn had achieved through discipline and endurance.

To the Onyx Dragons, the lesson was simple:

Some prey cannot be hunted.

It must be burned out—completely.

Operation Void Talon was a precision strike carried out in the void-shadowed reaches of the Halo Stars, where a Dark Mechanicum war-forge supplied traitor fleets with heretical war engines. Shielded by layered void defenses and a formidable anti-air network, the forge had proven impervious to repeated Imperial Navy assaults. Where bombardment had failed, the Onyx Dragons were called to hunt.

The war-forge—designation lost to Imperial record—was no simple station. It was a drifting manufactorum complex, bristling with macro-batteries, interceptor arrays, and void shields powerful enough to withstand sustained fleet engagement. Attempts to breach it through conventional means had resulted in heavy losses.

The Navy could not break it.

So the Onyx Dragons chose to blind it.

The Silent Approach

The 5th Company—the Skyshadows—was deployed under Captain Ravik Kael.

At this stage in the Chapter’s history, the Skyshadows operated as a Firstborn infiltration and strike force, composed of:

• Tactical Squads adapted for close-quarters void combat

• Scout elements for forward infiltration

• Assault Squads for rapid breach and close-range elimination

• Rhino and drop insertion methods modified for low-signature deployment

Under Kael’s command, the operation would not be an assault.

It would be a removal.

Using a system-wide dust storm—an anomaly of drifting particulate debris and electromagnetic interference—the Skyshadows masked their approach. Small insertion craft and void-adapted deployment pods slipped through sensor gaps, landing across the outer structure of the war-forge.

They were not detected.

The Infiltration

Once inside, the Skyshadows operated in dispersed kill teams.

Scout elements moved first, mapping internal pathways, identifying patrol routes, and locating key systems. Tactical Squads followed, establishing hidden positions within maintenance corridors, reactor access tunnels, and abandoned manufactoria decks.

No alarms were triggered.

Enemy patrols began to vanish.

Servitor relays failed without explanation. Vox traffic became unreliable. Entire sections of the forge fell silent, their defenders eliminated without a trace. The Skyshadows did not advance in force—they spread, embedding themselves throughout the structure.

By the time the enemy recognized the intrusion, it was already too late.

Marking the Prey

Kael’s objective was not to destroy the forge directly.

It was to prepare it for destruction.

Kill teams identified and marked:

• Void shield generators

• Anti-aircraft batteries

• Command and control relays

• Reactor stabilization systems

Each target was sabotaged, weakened, or primed for destruction. Charges were placed with precision. Redundant systems were quietly disabled. Escape routes were sealed.

The war-forge was being hollowed from within.

The Strike

At Kael’s signal, the Skyshadows moved as one.

Assault Squads launched simultaneous strikes across multiple decks, overwhelming key positions before alarms could propagate. Tactical Squads executed pre-planned eliminations of command personnel. Scout teams triggered demolition charges across shield nodes and defense arrays.

Within minutes:

• Void shields collapsed

• Anti-air systems went dark

• Command coordination fractured

For the first time since its discovery, the war-forge was exposed.

The Killing Blow

The Imperial Navy had been waiting.

With defenses neutralized, fleet elements translated into engagement range and unleashed full bombardment. Macro-cannon fire and lance strikes tore into the now-vulnerable structure, targeting the very systems the Skyshadows had crippled.

Inside the forge, Kael’s forces executed final withdrawal protocols, disengaging through pre-planned routes and extraction points as the structure began to fail.

The war-forge did not explode.

It came apart.

Layer by layer, its systems failed, its reactors destabilized, and its structure collapsed under sustained bombardment.

Aftermath

The destruction of the war-forge crippled traitor fleet operations in the region, cutting off a critical supply of war engines and munitions. Imperial naval forces regained control of surrounding systems, pushing Chaos elements back into the deeper reaches of the Halo Stars.

The Skyshadows suffered minimal losses.

Many of their actions were never recorded in full. Entire sections of the operation remain classified or unknown, even within the Chapter.

Legacy

Operation Void Talon stands as the defining example of the Skyshadows’ Firstborn-era doctrine: not a battle fought for dominance, but a hunt carried out through silence, precision, and control.

Where others sought to break the enemy through force, Kael proved that some prey does not need to be struck.

It needs to be undone.

By the time the enemy realizes the hunt has begun…

…it is already over.

The Dragon’s Wake marked the first full-scale deployment of the Onyx Dragons in the wake of the Indomitus Crusade, a campaign that demonstrated not only the Chapter’s enduring strength, but its transformation. What began as a drifting threat in the void became a proving ground for a new era of war.

The target was an ancient orbital megastructure, long thought abandoned, discovered adrift in the outer reaches of the Ultima Segmentum. Initial scans revealed the truth: the structure had been infested by Tyranid bioforms, its vast internal chambers converted into a living hive drifting toward an Imperial world.

If it reached orbit, the consequences would be catastrophic.

The structure had to be destroyed.

A Chapter Reforged

By this time, the Onyx Dragons had received Primaris reinforcements as part of the Indomitus Crusade. Many veteran Firstborn had undergone the Rubicon Primaris, while others continued to serve in their original forms.

The force deployed to intercept the structure reflected this transition:

• 2nd Company — Iron Claws (now a Primaris-dominant mechanized spearhead)

• 1st Company — The Scaled (newly transformed into an all-Primaris veteran force)

This was not a Chapter divided.

It was a Chapter reforged.

The Breach

The Iron Claws led the initial assault.

Rather than attempt external destruction, Captain Khaganth Veyr directed a coordinated boarding operation. Using heavy transports and armored insertion craft, the company breached the outer docking structures, establishing secured entry corridors into the megastructure.

Intercessor lines advanced methodically, supported by Heavy Intercessors anchoring each position. Dreadnoughts and armored units forced open pathways through chitin-reinforced bulkheads and organic growth.

The objective was not immediate destruction.

It was control.

War Within the Void

Inside, the structure had become a labyrinth of Tyranid infestation. Corridors twisted into organic tunnels. Chambers pulsed with bio-mass. Entire sections of the station functioned as breeding pits, spawning new horrors even as the battle raged.

The Iron Claws advanced as they always had—disciplined, relentless, and controlled—but now with the enhanced resilience and firepower of Primaris formations.

Where resistance thickened, the Scaled were unleashed.

The Killing Blow

The 1st Company struck at the heart.

Clad in their most revered wargear, the Scaled advanced into the deepest layers of the structure, where the Tyranid presence was strongest. Plasma fire, relic flamers, and master-crafted weapons reduced entire broods to ash as they pushed toward the central reactor core.

The fighting was unlike any planetary war. Gravity fluctuated. Entire sections were exposed to void. Tyranid organisms adapted continuously, emerging in forms designed to counter the advancing Marines.

Still, the Scaled pressed forward.

At the core, they found the nexus—a massive bio-organic control mass entwined with the station’s reactor systems.

It had to be destroyed from within.

The Dragon’s Wake

With the core breached, the Onyx Dragons initiated a controlled overload of the reactor systems.

The Iron Claws executed a fighting withdrawal, maintaining secured corridors as the Scaled completed the final phase. Extraction was conducted under constant assault, with gunships and transports navigating a collapsing structure filled with hostile bioforms.

Moments after the final units withdrew, the megastructure detonated.

The explosion tore the station apart, scattering its remains across the void in a blazing cascade of debris and fire. For hours afterward, the fragments burned in the darkness—a wake of destruction marking the end of the hunt.

Aftermath

The Imperial world the structure had threatened was saved.

The Tyranid infestation was annihilated before it could reach planetary orbit.

More importantly, the campaign proved that the Onyx Dragons had not merely survived the transition into the Primaris era—they had mastered it.

The integration of Primaris warriors, enhanced wargear, and refined doctrine allowed the Chapter to execute operations at a scale and efficiency previously impossible.

Legacy

The Dragon’s Wake stands as the moment the Onyx Dragons emerged fully into their new form.

The Firstborn had forged the Chapter in fire.

The Primaris carried that fire forward.

Together, they proved that the hunt does not end with change.

It evolves.

The Shroud Rift Incursion marked the first full realization of the Skyfangs’ modern doctrine, a campaign fought not across a battlefield, but against a threat emerging from beneath it. As a Necron tomb complex awakened within the unstable region known as the Shroud Rift, the Onyx Dragons moved swiftly to contain it—before its forces could fully phase into reality.

The Shroud Rift was a region of fractured space, its boundaries distorted by warp instability and gravitational anomalies. When augur arrays detected the emergence of Necron structures beneath its surface, Imperial authorities feared the birth of a full tomb world.

They would not be given the time to awaken.

The Skyfangs Deploy

The Onyx Dragons committed the 3rd Company—the Skyfangs, under Captain Vaedran Marr.

By this stage, the Chapter had fully embraced Primaris warfare, and the Skyfangs represented its most refined expression of speed and precision. Their formation for the incursion reflected this:

• Phobos-armored elements for reconnaissance and target designation

• Storm Speeder squadrons for rapid suppression of key defenses

• Jump-pack Intercessors and Vanguard Veterans for direct assault

• Inceptors and mobile fire teams for flexible support

This was not a sustained campaign.

It was a series of perfectly timed kills.

The Awakening Threat

The Necron complex did not emerge all at once. Instead, its structures phased into existence in segments—monoliths rising from the ground, energy nodes activating, and defensive systems coming online in sequence.

This staggered emergence created both danger and opportunity.

If allowed to complete its awakening, the tomb complex would become nearly impossible to dislodge.

But while incomplete, it was vulnerable.

Identify the Prey

Phobos units led the initial phase of the operation.

Moving ahead of the main force, they mapped the emerging structures, identifying key systems before they fully activated:

• Command nodes

• Phase relays

• Power conduits

• Defensive pylons

Librarian Aethon Khar—the Ash Seer—guided this process, interpreting shifting patterns of energy and predicting where the next emergence would occur.

The battlefield was not static.

It was forming in real time.

Break the Shell

Once targets were marked, Storm Speeder formations struck.

Hailstrike and Hammerstrike variants swept across the emerging complex, delivering concentrated fire against partially active defenses. Anti-air systems were destroyed before they could fully deploy. Power nodes were crippled mid-activation.

The Necron response was immediate—but incomplete.

Units began to phase into existence, but without full coordination, they were isolated and vulnerable.

Tear the Heart

At Marr’s command, the Skyfangs descended.

Jump-pack Intercessors, Vanguard Veterans, and command elements struck in coordinated waves, landing directly atop identified targets. The speed of the assault prevented the Necrons from establishing coherent defensive lines.

Each strike was localized and overwhelming:

• Command nodes were destroyed before control systems stabilized

• Phase relays were shattered, disrupting reinforcement cycles

• Emerging Necron units were cut down before full materialization

The Skyfangs did not hold ground.

They moved.

The Dragon’s Descent

This campaign marked the first recorded execution of the Dragon’s Descent doctrine in full.

Rather than a single assault, the Skyfangs conducted a chain of strikes:

1. Identify the next emergence point

2. Suppress defenses before activation

3. Deploy jump forces to destroy critical systems

4. Redeploy before counterattack

This cycle repeated across the battlefield, preventing the Necron complex from ever achieving full operational status.

Each strike weakened the whole.

Each movement denied the enemy time.

The Failing Awakening

As the incursion progressed, the Necron response intensified. Larger constructs began to phase in, and coordinated counterattacks attempted to pin the Skyfangs in place.

They failed.

Marr refused static engagement. Forces disengaged the moment resistance stabilized, redeploying to new targets before the enemy could respond effectively.

Without stable command and with critical systems repeatedly destroyed, the tomb complex began to falter. Its emergence cycle fractured, leaving sections incomplete and vulnerable.

The Final Collapse

With the complex destabilized, the Skyfangs initiated the final phase.

Coordinated strikes targeted the remaining power cores and phase anchors, triggering cascading failures throughout the structure. Without these systems, the tomb complex could not sustain its presence.

Rather than exploding, it collapsed.

Sections phased out of reality mid-activation, leaving behind fractured remnants and dead zones where structures had once begun to form.

Aftermath

The Shroud Rift was secured before a full Necron awakening could occur.

Imperial forces later established monitoring stations in the region, though the area remains unstable and under constant observation. No further large-scale emergence has been recorded.

The Skyfangs withdrew with minimal losses.

Legacy

The Shroud Rift Incursion stands as the defining campaign of the 3rd Company in the Primaris era.

It proved that speed alone is not enough.

Precision alone is not enough.

But when combined—when every movement is timed, every strike deliberate, and every withdrawal controlled—the enemy is never allowed to fight the battle it intended.

To the Onyx Dragons, the lesson was clear:

The hunt is not won by strength alone.

It is won by choosing the moment the enemy never sees coming.
