Graham McNeill - Mechanicum

'Thank Ares,' breathed Severine tearfully. 'Please? Can anyone help me? I think my arm's broken.'

'Dalia?' said Rho-mu 31. 'Are you all right?'

'Not especially,' she replied with forced levity, 'but I'll live, which is more than I thought I'd be able to say a few minutes ago.'

'Can you move?'

'Yes, but give me a minute.'

'We don't have a minute,' said Rho-mu 31. 'We have to move in case it comes back.'

'It won't come back,' said Dalia. 'It thinks we're dead, or at least it will for a while.'

'Then let's get out of here before it realises its mistake,' said Rho-mu 31.

In the upper reaches of Olympus Mons, Kelbor-Hal inloaded the encrypted data blurt from the Kaban Machine. Looking out over the surface of Mars he took a moment to survey the landscape, knowing that soon it would be transformed into something wondrous and new.

The power that boiled from the depths of the Vaults of Moravec was intoxicating, and every day brought fresh miracles as he and his fellow Dark Mechanicum - a term Melgator had coined - found new ways to bind it to the metal and gristle of their creations.

Weapons, servitors, praetorians and fighting vehicles were imbued with power, twisting them into new and terrifying forms that were divinely primordial in their savage beauty. Monstrous engines of destruction that would be the heralds of the new power rising in the galaxy were taking shape in Olympus Mons and the forges of those adepts and magi that had bound themselves to the cause of Horus Lupercal.

Billions toiled in the weapon shops and manufactorum to realise this grand dream of Mars resurgent, and none who touched the powers unleashed to roam throughout his forge remained unchanged.

Chants echoed from the darkened thoroughfares of Olympus Mons, mobs of hooded worshippers hunting down those who did not embrace the new way and feeding their blood to the hungry machines. Brazen bells tolled constantly and howling klaxons shrieked with the godlike power of the scrapcode.

The transformation of his forge was a magnificent thing, and Kelbor-Hal knew that what they did here would echo through the ages as the moment the Mechanicum was reborn.

He turned from the armoured glass of the viewing bay to face his followers.

Regulus, Melgator, Urtzi Malevolus, together with holographic images of Lukas Chrom and Princeps Camulos, stood attentively before him. He could see the cluttering lines of scrapcode infesting their augmetics.

He nodded towards Lukas Chrom. 'Dalia Cythera is dead. Once again, your assassin and thinking machine prove their worth.'

Chrom accepted the compliment with a short bow.

'Then it is time?' said Princeps Camulos. 'My engines long to make ruin of the Magma City.'

The bear-like Princeps Senioris of Legio Mortis was clad in beetle-black armour and Kelbor-Hal read the warp-enhanced aggression flaring from him in waves.

'Yes,' he said. 'It is time. Send word to the commanders of your allied Legios, Camulos. Tell their engines to walk and to crush our enemies beneath their mighty treads.'

'It shall be done,' promised Camulos.

Kelbor-Hal then addressed his fellow adepts of the Dark Mechanicum.

'This is a great day, my acolytes, remember it always,' said the Fabricator General. 'This is the day Mars and her forge worlds cast off the yoke of the Emperor's tyranny. Unleash your armies and stain the sands of our planet red with blood!'

Later histories would record that the first blow of the Martian civil war was struck against Magos Mattias Kefra, whose forge in the Sinus Sabaeus region was housed within the Madler crater. Titans of the Magna Legion marched from the southern Noachis region and within minutes had smashed down the gates of his forge. Howling engines daubed in red, orange, yellow and black, and decorated with flaming horned skull devices, ran amok within the high walls of the crater, crushing everything living beneath them and destroying thousands of years of accumulated wisdom in a fury of fire.

Vast libraries burned and weapon shops that served the Solar Guard were reduced to molten slag as the indiscriminate slaughter continued long into the night, the Magna Legion's trumpeting warhorns sounding like the atavistic screams of primitive savages.

Further north in the Arabian region, the great engine yards of High Magos Ahotep in the Cassini crater were struck by a hundred missiles launched from the atomic silos secreted within the isolated peaks and mesas of Nilo Syrtis. The explosions of the forbidden weapons filled the four hundred and fifteen kilometre diameter of the crater with seething nuclear fire, and sent conjoined magma-streaked mushroom clouds soaring nearly seventy kilometres into the sky.

Along the borders of the Lunae Palus and Arcadia regions, what had previously been confined to heated debate erupted into outright warfare as Princeps Ulriche of the Death Stalkers unleashed his engines upon the fortress of Maxen Vledig's Deathbolts.

Caught by surprise, the Deathbolts lost nineteen engines in the first hour of battle, before withdrawing into the frozen wastes of the Mare Boreum and seeking refuge in the dune fields of Olympia Undae. Their calls for reinforcement went unanswered, for all of Mars was tearing itself apart as the plague of war spread across the planet in a raging firestorm.

Amid the Athabasca Valles, war machines of Legio Ignatum and the Burning Stars fought in bloody close quarters through the teardrop landforms caused by catastrophic flooding in an earlier, ancient age of the red planet. Neither force could gain the advantage, nor could either claim victory, so after a night's undignified scrapping, both withdrew to lick their wounds.

A snapping, howling host of twisted skitarii and hideously altered weaponised servitors surged from the Gigas Sulci sub-hives of Olympus Mons to attack the crater forges of Ipluvien Maximal. Alert to the danger of attack, Maximal's forces repelled the first waves of attackers, but within hours, his forge was surrounded and under siege by unholy Ordinatus engines and warped machines given hideous life in the depths of the Fabricator General's darkest and bloodiest weapon shops.

The greatest single loss of life took place in the Ismenius Lacus region of Mars, where the glacial forges of Adept Rueon Villnarus were attacked by airbursting rockets carrying a mutated strain of the Life Eater. The rapacious viral organism leapt from victim to victim with malicious glee, seeming to travel via every possible vector. Via direct contact, it killed the tens of thousands directly exposed to the detonation in minutes. Airborne, it depopulated the millions-strong worker-habs of Deuteronilus Mensae within three hours, and through some diabolical warp-mutation, it spread through the haptic networks to infect even those who thought themselves safe behind vac-sealed barriers. When the gleeful virus finally burned itself out, some seven hours later, every living soul within Ismenius Lacus was dead, the remains of fourteen million liquefied corpses freezing solid where they lay.

Within the Herschel impact basin of the Mare Tyrrhenum, nine hundred thousand skitarii and Protectors clashed in a swirling, bloody melee that continued unabated until almost all were dead. No victor emerged from the senseless slaughter and no purpose was served by the destruction, yet still both factions poured their forces into the meat grinder for fear of what might be lost should they withdraw.

Nor was the fighting merely confined to the surface of Mars. The Ring of Iron, that great halo shipyard that surrounded the red planet like a glittering silver belt, shuddered as explosions and conflict spread along its length. Factions loyal to the Throne, and those sworn to Olympus Mons and Horus Lupercal, clashed with the fury of fanatics. The vessels of Battlefleet Solar pulled away from the fighting as Mechanicum ships duelled in the shadow of the Ring of Iron, pounding one another with devastating broadsides and no thought of strategy or survival.
