Exemplary Battles
As the Age of Darkness ground ever onwards, the fires of war would spread throughout the entire galaxy, consuming everything in their path. Armies and worlds were reduced to nothing more than ash, in many cases leaving no one alive to bear witness to the sacrifices made or the atrocities committed. During this time, each Legion employed unique formations to prosecute their own style of war, whether by choice or through necessity, making use of unconventional, often abhorrent, tactics and weapons. Many of these formations would be lost during the dark years following the Horus Heresy, their traditions wiped out and the last stockpiles of their weapons exhausted. Some, however, have been preserved in these records, that future generations may learn of the terrors unleashed upon the galaxy by the Emperor’s turncoat sons and the valiant heroes who stood against them.
The Battle for the Kalium Gate

The Kalium Gate was a technological marvel, the origins of which had been lost in the dark and tumultuous aeons that preceded the Emperor’s reign. Located in the Kalium system of the Segmentum Obscurus, the Gate was made up of a series of interlocking void stations connected together by colossal bundles of kilometreslong cables. Extant records indicate that it was discovered in a dormant state by Imperial forces during the early years of the Great Crusade, but its principal value was quickly realised by the strategos of the Imperial Administratum. Once awakened, the Gate could send entire war fleets through the Warp, across unimaginably vast distances on great aether-currents, making journeys that took several Terran standard years last only a handful of weeks. The Gate became a nexus for interstellar travel in the Segmentum Obscurus but efforts to restore it to its full potential were cut short with the outbreak of the Horus Heresy – when Primarch Perturabo led the IVth Legion (Iron Warriors) in a destructive assault that left the Gate a smouldering tomb, reduced almost to the dormant state it had been in when it was first discovered.
In the latter half of 010.M31, the Vth Legion (White Scars) was cut off in the Segmentum Obscurus and surrounded on all sides by overwhelming enemy forces. Loath to waste the lives of his sons in pitched battles, the Primarch Jaghatai Khan desperately sought a way to evade his foes and reach the Sol System ahead of the Warmaster’s hosts. Chief among the Khan’s pursuers was Lord Commander Eidolon – a vainglorious and arrogant warrior who, in the absence of his Primarch Fulgrim, had become the self-appointed master of the IIIrd Legion (Emperor’s Children). Seeking to validate his newfound pre-eminence among the Emperor’s Children, Eidolon hounded the White Scars across the stars, believing the prize of Jaghatai Khan’s head would earn him the recognition he so craved. With his Legion bloodied and lacking the sheer numbers required to break through the Traitor lines, the ever-resourceful Khan devised a plan to deceive the enemy and draw their strength away from the main concentration of his force. In the wake of the destruction unleashed by the Iron Warriors, elements of the Emperor’s Children Legion had moved in to rebuild the Kalium Gate’s fearsome defences, not only to secure
and plunder an asset of strategic value, but also to prevent the Loyalists from re-awakening its arcane technologies and using it to escape. The Khan sent the hardened veterans of approximately six Brotherhoods – formations shattered in past battles against Eidolon’s hunter-killer fleets but hungry for vengeance – to attack the Kalium Gate. The Dictatus class battleship, Lance of Heaven, led the attack; one of the Legion’s oldest vessels and veteran of a dozen major engagements since the outbreak of the Horus Heresy. Alongside the Lance of Heaven came seven venerable warships, surrounded by a swarm of smaller frigates, destroyers and other support craft. The White Scars ships hurtled towards their target with the speed their Legion was famed for, leaving the enemy’s auspex grids to chase after shadows while the Khan’s sons closed in for the kill, their guns and torpedoes primed. The Emperor’s Children war vessels that rose from the shadow of the Kalium Gate to oppose the sleek White Scars cruisers were of equal displacement to their counterparts and, though fewer in number, they were bolstered by the heavy gun batteries and defensive emplacements of the Gate. Having paid a heavy price
in blood during past engagements with the Khan’s sons, the Emperor’s Children had learned well not to underestimate the cunning and unpredictable tactics of the White Scars. The heavy warships of the IIIrd Legion and accompanying escort vessels spread out to engage the incoming White Scars flotilla, creating a defensive cordon that would hold the Loyalist onslaught at bay long enough for the Emperor’s Children manning the Gate’s defences to prepare for the inevitable ground attack. Long range guns opened fire, sending beams of superheated energy lancing though void shields to pierce the flanks of warships and kill thousands of the ships’ crew in the space of a single heartbeat. Macro cannon shells and cluster warheads buckled and shattered armour plates on impact, setting off chains of devastating internal explosions that blew apart entire sections of superstructure, leaving dozens of vessels aflame and dead in the void. As the two fleets closed the distance between them, vicious boarding actions were launched and terrible destruction was unleashed across multiple ship decks as Legionaries sought to cripple or capture enemy vessels.
White Scars vessels burst through the defensive cordon of the Emperor’s Children ships, pushing their reactors to breaking point as they desperately tried to close the distance with the Kalium Gate. The Gate’s fearsome defensive weapons spoke as one and the first vessels to emerge from the tumult of the naval battle, recorded to have been the frigates Horselord and Hunter of the Plains, took the full brunt of their fire and were simply erased from existence. Larger White Scars battleships soon reached the Gate, their void shields straining under heavy fire from its fearsome defensive batteries, but this time it was the Loyalists’ turn to unleash their fury upon the Traitors below. The space surrounding the Gate’s void stations became a sea of fire as lance strikes and punishing fusillades from bombardment cannons thundered against faltering power fields raised over the defences. Here and there, these shield barriers shuddered and failed, leaving mobile defence launchers and gun emplacements unprotected from the devastating guns of the White Scars warships, which obliterated both the weapons and their crews.

Hard on the heels of the destructive barrage came swarms of fighter craft and heavy attack landers carrying the warriors of the Ordu, the horde of Jaghatai. Fire Raptors and Xiphon interceptors dived from above to strafe enemy positions with their deadly payload of high-calibre bolt shells and missiles, forcing the Emperor’s Children to seek shelter behind shielded curtain walls or within prefabricated bunkers as the Gate’s infrastructure disintegrated around them in a maelstrom of explosions. Thunderhawk gunships touched down on the cavernous hangars of the colossal void docks, disgorging hundreds of Legionaries among the scattered detritus and silent machinery of the Gate’s long dead past. Breacher and Tactical squads swiftly moved to clear the surrounding areas of defenders with blade and boltgun, giving the Emperor’s Children no mercy and expecting none in return. The White Scars proved relentless in the pursuit of their objectives, venting their repressed fury on the warriors of the Legion that had hounded them for years. The assault of the first wave was executed the way the White Scars had always taken joy in waging war – hard and fast, with an artful precision and timing that allowed the enemy no time to react. With the primary objective of securing the Legion’s landing sites achieved, the White Scars next moved to silence the Gate’s mighty defence batteries. Stormbird attack landers were brought in to form mobile firebases that could withstand heavy ground fire while their cargo of troops, war machines and mobile gun platforms disembarked. Armoured columns of Sicaran battle tanks and Rhino armoured transports filled with Vth Legion Despoiler squads were deployed on the hard permacrete floors and steel sheeting of the hangars to press the attack, turning the battle into something more akin with fighting across the surface of a dwarf planet. Void Dock Theta-4 and Void Dock Theta-5 quickly fell to the relentless attack of the White Scars, their berthing zones overrun by Loyalist troops and vehicles.
