The Legio Krytos ("God Breakers") is a Traitor Titan Legion of the Dark Mechanicum that repudiated its oaths to the Emperor of Mankind and followed the Warmaster Horus into the service of the Ruinous Powers during the Horus Heresy. It was based on the world of Krytos.

The Legio Krytos is known to have participated in both the infamous Battle of Tallarn and the Battle of Beta-Garmon. Even before the outbreak of the Heresy, this notorious Titan Legion were known to be excessive in their pursuit of achieving Imperial Compliance and levelling cities that showed even a shred of defiance.

The God Breakers were also known for making extensive use of Earthbreaker Missiles -- specialised weapons that were designed to burrow into the ground before detonating, tearing the terrain apart in showers of broken earth. These weapons were used extensively by the Legio Krytos to bring down fortifications, but they also proved effective in slowing the advance of enemy maniples.

Perhaps as a result of these preferences in waging war, the Legio Krytos tended to work closely with the siege-breaking Iron Warriors Legion. The two working in concert often reduced worlds to smoldering wastelands, inhabited by guttering cities and bleached skeletons.

Legion History

Even before the brutal wars of the Horus Heresy, this Titan Legion was known for their excesses in bringing planets to Imperial Compliance and levelling cities that dared showed even a shred of defiance.

As the Heresy progressed, the God Breakers perfected their methods of scorched earth, often fighting alongside the Iron Warriors Legion to reduce a planet to smouldering wastelands, inhabited only by guttered cities and piles of grinning skeletons.

It would be upon the savaged world of Tallarn that the Legio Krytos made their lasting mark.

Notable Campaigns

  • Battle of Tallarn (010-012.M31) - During the Horus Heresy, Perturabo, Primarch of the Iron Warriors, launched an all-out planetary invasion of the verdant Imperial staging world of Tallarn, his IVth Legion bolstered by dozens of allied Traitor Imperial Army regiments, the Titans of the Legio Krytos and the Knights of House Caesarean. Both the Loyalist and the Traitor high commands were taken by surprise by Perturabo's actions and the invasion quickly escalated after he ordered an Exterminatus upon the world, scouring its surface of living matter by way of a voracious Life-eater virus bomb barrage. While the population of the once-verdant world was all but wiped out, many defenders survived thanks to extensive subterranean shelters. The ensuing campaign was fought between vast formations of Imperial Army and Solar Auxilia tanks, the Titans of the Legio Gryphonicus, the Knights of House Megron, the indentured Battle-Automata of the household army of the Rogue Trader Sangrea as well as the armoured forces of the Iron Hands, Imperial Fists, White Scars and Ultramarines Legions. No infantry could survive in the poisoned wastes, and the war quickly drew in other forces from across the Segmentum Tempestus. The Battle of Tallarn is considered the largest armoured engagement in the known history of Humanity, and while counted as a victory for the Loyalists, millions of warriors and war machines on both sides were left scattered across the lifeless, deadly surface of the planet.
  • Battle of Beta-Garmon, The "Titandeath" (006-013.M31) - The Legio Krytos took part in the long and savage Beta-Garmon campaign, which included hundreds of war zones across dozens of worlds. Even before the greater armies of the Warmaster Horus reached the star cluster, the battle lines had long since been drawn, and fighting had been going on for many Terran years. It was a cauldron of battle that would consume millions of lives before its end and see the demise of entire Titan Legions, earning this campaign the dire moniker, the "Titandeath." The Beta-Garmon Cluster, also known as the gateway to the Throneworld of Terra, was the last hurdle that the Warmaster Horus' forces had to overcome before they reached the Imperium's capital world. Heavily fortified by the Loyalists, Beta-Garmon would become one of the greatest and bloodiest battles of the Horus Heresy, as well as one of the longest lasting. Even as the fires of Istvaan III were cooling, Alpha Legion attack cruisers entered the cluster. A campaign of assassination and sabotage unleashed by the XX Legion paved the way for an assault by an Emperor's Children Millennial, seeking to win back the favour of Fulgrim by bringing the Garmonite lords of Beta-Garmon II to heel. Meanwhile, the Traitor Titans of the Legio Mortis "Reaper" Titan maniples swept away the Loyalist Nemesis brigades defending Beta-Garmon II's capital of Nyrcon City in a matter of solar days. After Nyrcon and the orbiting star fort known as The Anvil were taken, forces across the cluster declared for or against the Warmaster and many of the cluster's worlds descended into civil war.
    • Beneath a Blood Red Star (361.012.M31) - The God Breakers came to Alpha-Garmon IX with the order to level the world and rob the Beta-Garmon Cluster of its harvested energy in preparation for the wider Battle of Beta-Garmon. Anticipating the arrival of the Traitor Titans, the planet's Loyalist Martian Domini called out to the Legio Atarus and Legio Astorum for aid, while massing their own regiments of Mechanicum Knight Houses. The resulting conflict turned the black plains of Alpha-Garmon IX to glass with the fury of battle, while Dark Mechanicum War Servitor clades and mutant levies clashed in the tunnels below with the defenders. During the battle, many of the world's tesla-spines are felled -- their kilometres-long spires crashing down among the fighting Titans.
    • The Titandeath (356.013.M31) - More than twenty Legios and hundreds of Titans converged on Beta-Garmon II as the Loyalists sought to strike a decisive blow to reclaim Nycron City and clear the system of Traitors. Shoulder to shoulder, the Loyalists met their enemies in battle like infantry formations facing off, only on a much grander scale. Knight banners raced around their feet like hunting hounds. Many Titan Legions are extinguished forever in the days of battle that followed, and even legendary formations such as the Legio Astorum and Legio Fureans are reduced to a fraction of their initial size. By the time that the Loyalists reached the shattered walls of Nycron, both sides were staggering over fields of fallen god-machines, while the light from Beta-Garmon II's burning hive cities was visible from space.
    • The Needle Breaks (788.013.M31) - The tipping point of the Beta Garmon campaign comes in the shadow of the Carthega Telepathica on Beta-Garmon III, its astropaths still screaming out for aid from Terra. Having pinned the bulk of the Loyalist forces against the defences of Caldera Hive, only a handful of Loyalist Titans drawn from different Legions defend the Diviner's Needle along with their Knight allies, among them the Legio Defensor, Legio Astorum, Legio Atarus and Legio Solaria -- some reduced to a single maniple of undamaged war machines. Unbroken by solar months of fighting, the Legio Mortis led a massive host of Traitor Titan Legions against the tower's defences, the Titans and Chaos Knights marching up through the toxic storms to battle on the mountain top, and ultimately bring the spire down. As it fell, a psychic scream reached out across the cluster and beyond, spreading dismay and horror to all Loyalists it reached. Though the fighting at Beta-Garmon continued until Horus stood at the gates of Terra, and long after, history recorded this as the point when the fate of the cluster was sealed, and the Warmaster's armies began their final march toward the heart of the Imperium.

Legion Combat Doctrine

Legio Krytos is a hammer that knows only one way of waging war -- to crush its enemies utterly beneath the repeated blows of its Titans.

While the Legion fields Warhound and Reaver Titans, its commanders favour deploying its Warlord Titans into potent battlegroups, and use their massed firepower to obliterate opponents.

The God Breakers' maniples are methodical in their destruction of the battlefield, turning forests into seas of flame and buildings into clouds of dust and ash. Over the course of the Horus Heresy, their princeps mastered the means of bringing down structures, and were experts at identifying their weak points.

The swirling flames of a dying world can be a hostile environment, even for a great god-machine like a Battle Titan. The God Breakers routinely endured these adverse conditions, and developed tactics to deal with them.

Notable Titans

  • Hammer of Tyrants (Warlord-class Titan) - Warlord Battle Titans are among the greatest war machines of the Collegia Titanica and among the God Breakers, these towering beasts are revered as deities of destruction. Hammer of Tyrants, show above, fought in the Delta Garmon II landings and bore the scars of this battle upon its armoured plates. While other Legions busied themselves restoring the heraldry and iconography of their god-engines, the Legio Krytos allowed their enemies to see that their maniples had already tasted war and embraced the carnage they had wrought upon their foe.
  • Black Arrow (Reaver-class Titan) - Black Arrow was typical of those Reaver Battle Titans that the Legio Krytos used on Beta Garmon II during the assault on Hive Caldera. In this battle, the God Breakers used their Reaver Titans as a spearhead to reach the hive city's gates before the storm closed in, while Warlord Titans provided covering fire and Warhound Titans covered the flanks. It proved to be an effective tactic, the relative speed and armour of the Reaver making it well-suited to the task of creating a breakthrough and then exploiting it fully.
  • Apostate of Days (Warhound-class Titan)
  • Curse of Iron (Warhound-class Titan)
  • Grateful Punishment (Warhound-class Titan)
  • Havoc (Warhound-class Titan)
  • Manus Infernum (Warhound-class Titan)
  • Night's Hunter (Warhound-class Titan)
  • Oedium Aelemium (Warhound-class Titan)
  • Tyrant's Torment (Warhound-class Titan)
  • Wolf Scythe (Warhound-class Titan)

Notable Personnel

  • Yavar the Pitiless - Yavar the Pitiless was the Princeps of the Warhound-class Titan Grateful Punishment during the Horus Heresy. In the closing days of the Beta-Garmon campaign, Yavar led the Legio Krytos Lupercal Light Maniples. Its Princeps at first resented his role, jealous of his peers tasked to heavier Titans and siege breaking tactics. By the end of the war though, Yavar had learned the true joy of crushing the wounded and weak beneath the tread of his Warhound, ultimately earning a dark reputation for the Grateful Punishment and the Lupercal Light Maniple as a weapon of war.

Legion Badge

This Traitor Titan Legion's badge is a stylised winged warhammer known as the Hammer of Krytos centred upon a livery shield containing the Legion's heraldic colours of white, green and red.

When the Legion turned Traitor, this seal was often hammered over icons of allegiance to the Emperor, masking the Aquila or the Cog Mechanicum symbols of Mars.

The Hammer of Krytos harkens back to the Legion's origins and the mythos of its Forge World, reputably wrought from a dead rock by the Omnissiah's hook-tooth hammer.

Beyond these icons of the Legio, Krytos banners bear the signum nobilis and campaign skulls of their kin, though the God Breakers like to show the scars of battle upon their maniples, and so many of their war banners show the tears and rents of recent action, with some even reduced to tattered rags bearing only a faint trace of the Legio's colours.
