Naval drop-ships formed an inner boundary, seventeen of them so far, as many again still arriving from orbit. Some were tank carriers, flat and broad, with wide doors that allowed their cargoes to disembark three abreast. The troop barges were longer and narrower, hundred-strong columns of infantry emerging at the double.
‘A labour misspent, Brother Chapter Master.’
Odaenathus turned at the metallic growl of Ancient Selatonus. The Dreadnought approached from the right, the top of his armoured plates almost level with the roof of the Land Raider. Encased within the plasteel, ceramite and adamantium giant were the system-sustained bodily remnants of a Space Marine, a great hero from the battles of Calth-That-Was.
‘Misspent, Venerable Brother?’ Odaenathus reviewed his dispositions and could see nothing amiss. ‘What labour goes awry?’
‘Siege lines… Supply corridors… These are the works of an occupying force, Chapter Master,’ the Dreadnought said, every word from his vocalisers heavy with artificially intoned gravitas. He raised a claw-tipped power fist and pointed towards the distant objective. ‘We come to kill the Great Beast. Our sojourn here will not last long, in victory or defeat.’
Odaenathus thought about this for several seconds, reviewing the situation. It was a planetary landing on an unprecedented scale. There were protocols and doctrines to ensure all passed smoothly. He caught himself, realising the error of his logic. The landings were unprecedented by his experience, but for a veteran of the Heresy Wars they were a straightforward incursion.
‘What counsel would you share, Ancient One?’ he asked the Dreadnought.
‘Speed in all things, Chapter Master. The Astra Militarum are capable of fending for themselves. We should strike for the city as soon as possible.’
The Chapter Master nodded and moved back to the hatch. He needed to request fresh orders from the Lord Commander.
From the observation platform of the Praetor Fidelis, Field-Legatus Otho Dorr could more clearly see the odd topography of the landing zone. From orbit it had looked like a series of eight mesas, each rising a few hundred metres from the wastelands’ mean level. On the upper gallery of his Capitol Imperialis command vehicle, itself forty metres high, the regularity, the sheer flatness of the surrounding rocky plateaus, struck him as conspicuous.
The immense war engine rumbled on, its tracks leaving metre-deep trails of compacted ash and dust. Around the Praetor Fidelis smaller tanks and assault gun squadrons moved away from the landers, following the command vehicle like the tail of a comet. Sentinel walkers and Rough Rider companies moved ahead to scout the best route for the Praetor Fidelis and more super-heavy tanks descending in the next wave.
A sudden vibration silenced the chatter of vox-operators and junior officers. Dorr felt the movement again, a shift in the ground significant enough that it could be felt through the grinding of the Capitol Imperialis’ tracks and the constant rumble of its engines.
‘Galtan!’ His staff lieutenant snapped to attention at the sound of his name. ‘What was that? Contact the tech-priests immediately. I want…’
The next tremor caused the lumen fittings to sway from the ceiling. Several of the deck’s occupants had to grab their consoles to stop themselves tipping from their stools. Dorr swayed with the movement, stumbling as he took a step towards the reinforced windows.
Looking down he saw that several of the surrounding vehicles had bogged down, caught as shifting dunes slid into newly formed dells littering the canyons between the plateaus.
‘Sir, look at the rock faces!’
Galtan’s call drew the field-legatus’ gaze to the cliff a few hundred metres directly ahead of the Praetor Fidelis. Boulders tumbled in a shower of dust. Through the murk of the landslide he saw racks run up the length of the rock. Stone split along unseen fault lines, thousands of tonnes of rock shearing away as something beneath — within — moved.
Alarm sirens shrieked from half a dozen positions as the ground lurched again, tipping the Capitol Imperialis to the left. Men and women tumbled across the observation deck and mechanical howls of protests shuddered through the war machine as drive systems tried to continue pushing the tilting Praetor Fidelis into the growing drifts of rock, sand and ash.
‘All drives to idle!’ barked Dorr.
‘Sir…’ Galtan’s hand tugged at the field-legatus’ brocaded sleeve. ‘You have to come to the gyro. I’ve ordered full staff council evacuation.’
‘You’ve ordered…?’
‘My prerogative, field-legatus.’ The junior officer signalled to a stern-faced commissar standing by the stairwell that led up to the flight platform atop the command vehicle. ‘Strechan will look after you.’
‘Come with me, sir.’ Strechan’s tone suggested he would brook no argument. His hand on the butt of a shock maul indicated he was also willing to take physical measures to ensure the field-legatus’ safety.
Dorr allowed himself to be hurried up the stairs. Emerging onto the flight platform he saw that the Capitol Imperialis had heeled over almost twenty degrees. The recon gyro — a four-rotored flyer capable of carrying five men in addition to the pilot — was still tightly gripped by landing claws.
‘What is happening?’ Dorr demanded, stepping away from the gaggle of officers surging up the stairs behind him.
Strechan looked as though he might intervene but stopped as the field-legatus directed a glare at him.
‘You may have the authority to detain me, commissar, but I would think twice about exercising it.’
The towering rock plateaus were falling to pieces, revealing glinting metal beneath. Like petals unfolding, huge plates hinged down, unleashing crushing deluges of rock onto the men and tanks between. Looking behind, Dorr could see one of the massive structures fully opened. Where there had been a mesa of solid stone — so he had thought — he could see a pointed dome at least a hundred metres across. It was painted in huge checks of red and black.
‘Is that…?’
‘Yessir,’ Galtan said hurriedly, seizing hold of the stunned field-legatus’ belt to drag him towards the open doors of the gyro. The blades started to spin, the whine of motors almost lost under the tumult of falling rocks and the shrieks of pulverised tank armour. The cacophony swallowed the screams of the dying, their last cries passing unheard forty metres below.
Bundled into the gyro, Dorr had not even strapped on his safety harness when the engines pitched to a shriek and he felt the craft lift away. Already at an awkward angle, the gyro sheared sideways towards the grey-and-black avalanche, until the pilot heaved the flyer into a swift climb. A cloud of choking ash and dust mixed with exhaust smoke swept through the still-open door of the compartment, coating uniforms, lips and skin with powdery residue. The updraught shook the gyro, its rotors rattling through stone splinters.
The field-legatus shouldered past Galtan, noting that Commissar Strechan had remained behind on the stricken Capitol Imperialis. Through the murk, wiping grit from his eyes, Dorr looked out of the ascending gyro, able to see across the expanse of the landing zone.
He could not credit his own senses at first, but the impossible forced its way into recognition. Where there had been rock and wilderness, now Dorr watched eight missiles push up from their silos, each defying sanity with their size.
‘We have to warn the others,’ he croaked, swallowing dust.
A captain manning the vox-station looked at him, the blood drained from his face. He was holding the speaker-piece against his ear to listen over the continuing storm of noise.
