Nemiel and the rest of the squad rushed to the downed Astartes. The air around Askelon shimmered with heat, radiating from his overloaded power unit. The Techmarine turned his head; squawks of sound crackled from his helmet's speaker. Nemiel didn't have to hear the words to know what Askelon was trying to say.
'He's sent the pulse,' Nemiel told the squad. 'Brother Marthes, take point. Sergeant Kohl, help me with Brother Askelon. Let's move!'
The Astartes sprang into action, charging down the tunnel behind Marthes, who advanced with his meltagun held ready. Kohl and Nemiel brought up the rear, dragging the limp form of Askelon between them.
Three hundred metres down the tunnel, the passageway fed into a large, square structure that echoed the permacrete blockhouse they'd entered at the manufactory. The plasteel rungs of another ladder climbed upward, presumably into the foundry's assembly building. Sitting at its feet, just as Nemiel suspected, crouched a matte-black sentry gun. Armed with a turret-mounted twin-linked lascannon, the automated unit crouched on four stubby legs like a hungry spider waiting for prey. Nemiel could hear the hum of its power unit as they approached. Its twin guns were aimed straight down the tunnel at the approaching Astartes. A single shot would cut through their armour like tissue.
'Up the ladder!' he ordered the squad. 'Get up and get out of sight!'
Marthes stepped around the sentry gun and began climbing at once. Vardus paused at the bottom rungs, his heavy bolter slung at his side. 'What about Askelon?' he said.
'We'll manage,' the Redemptor shot back. 'Now hurry, brother!'
Vardus started his climb, with Ephrial hot on his heels. Nemiel consulted his internal chrono: they had just twelve seconds left. He looked to Kohl as they reached the bottom of the ladder. 'We need to find a way to shut off the sentry gun,' he said. 'There must be an access panel—'
Askelon shook his head sharply; the ceramite edges of his helmet scraped against his gorget, suggesting he'd sustained damage to his armour's muscle fibres. 'No,' he said, his voice coming through his helmet's damaged speaker as a tortured croak. 'Can't risk it. I… I can climb.'
'All right,' Nemiel growled. 'You go first. Kohl, you're next. Help him as much as you can.' He would stay until the last moment; if they ran out of time, he would tear open one of the sentry gun's access panels and try to shut it down.
Askelon grabbed hold of the metal rungs and started climbing, seeming to gather strength with each lunge of his legs. Kohl was right behind him, ready to provide a judicious shove if the Techmarine faltered. Nemiel counted the seconds and checked the sentry gun for likely access points.
Vardus and Ephrial leaned over the hole, grabbed Askelon's folded servo-arm and hauled him bodily up into the chamber above. Kohl raced up behind him. 'Clear!' he hissed to Nemiel.
The Redemptor leapt for the rungs and scrambled upwards as quickly as he could. The timer on his display hit zero when he was halfway up. There was a series of rapid clicks and whirring sounds directly beneath him as the sentry gun sprang back to life.
Hands reached down and grabbed the edges of his pauldrons. Nemiel felt himself yanked upwards like a sack of grain and deposited roughly on the permacrete of the upper floor.
The Astartes froze, listening intently. Below them, the sentry gun clattered and whirred a moment more, then resumed its quiet vigil.
Nemiel looked over at Askelon's prone form. 'Any sign of alarm?'
The Techmarine reached slowly for his helmet and undid its clasps. Askelon pulled the helm away, revealing a sweat-streaked face stippled with broken blood vessels. A trickle of blood seeped from his nose and the corners of his eyes. 'No change,' he said in a husky voice. Blood slicked the Techmarine's teeth.
Nemiel rolled over and rose to his knees beside Askelon. 'How badly are you hurt?' he asked quietly.
Askelon chuckled faintly. 'I'm no Apothecary, brother,' he replied. 'The machinery of a living body is too complex even for me.' He levered himself to a sitting position with a grunt. 'Armour integrity is at sixty-five per cent. Power levels at forty per cent. Muscle fibre reflex is compromised, and I think I melted the motors on my servo-arm.'
Nemiel frowned. 'You didn't mention that tapping those conduits would likely kill you,' he growled.
The Techmarine managed a grin. 'It didn't seem relevant at the time.' He extended his hand. 'Help me up, please.'
Kohl and Nemiel hauled Askelon upright. The Redemptor glanced warily at the edge of the hole. 'Can the gun sense us up here?'
'To a limited extent, yes,' the Techmarine said. 'But activity overhead won't trigger a combat response. It's down there to guard the approaches to the building, and that's all.'
'All right. Where do we go from here?'
Askelon looked about the chamber. It was identical to the conduit room at the manufactory, only substantially larger. He nodded to the metal door across the chamber. 'That leads out into a sub-level beneath the main assembly floor. From there we'll be able to access almost every pan of the building.'
Nemiel checked his chrono again. It was little more than an hour until dawn. 'A building like this is bound to have catwalks along the upper storeys, correct?'
Askelon nodded. 'Three levels of them, in this case. You can look out over the entire assembly area from some of them.'
'Then that's where we need to be,' he said. 'Let's go.'
* * *
Kohl took point after that, leading the squad through the confines of the sub-level according to whispered directions from Brother Askelon, until they reached a narrow stairwell that climbed upwards into the assembly building proper. Weapons ready, they made their way carefully up the permacrete stairs, listening for the slightest sound of movement. Nemiel could hear the sharp crackle of arc torches and the snarl of power tools reverberating through the walls, the steel-on-steel noise like the sounds of a distant battlefield.
They climbed up several storeys, past one dimly-lit landing after another, until Nemiel signalled for a halt. 'This is far enough,' he said. 'We don't need to get all the way to the top; I just want a good view of what's going on,' he told them. He turned to Askelon. 'Is there any risk of sensors at this point?'
'No,' the Techmarine replied. 'We're past their detection perimeter at this point.'
'All right. Marthes, you and Vardus stay here and cover the stairwell. Kohl, Askelon and Ephrial, you're with me.'
Nemiel crouched at the plasteel door and cracked it slowly open. Beyond, the gantry-way was lit with red light from below. His autosenses picked up the reek of melted plas, petrochemicals and heated metal. Distantly, he could make out the sharp blurts and squeals of binaric cant, as well as a number of voices speaking in Gothic. The Redemptor concentrated, but he could make out what they were saying over the squalling of the machinery.
He surveyed the gantry-way carefully for as far as he could see, checking for any signs of movement, then went back and checked again. Satisfied there was no one within the immediate area, he opened the door the rest of the way and crept quietly onto the plasteel catwalk.
The assembly building was rectangular in shape, with an open floor plan surrounded by six huge niches that stretched from floor to ceiling. Giant servo arms were set into either side of these niches, able to climb to different heights along trackways set into the permacrete, and huge cranes hung from similar tracks high overhead. The Titans were assembled inside each niche, starting with the skeletal structure of the feet and working upwards to the head.
Nemiel found himself crouched on a section of third-storey gantry-way at one end of the building. The storeys above him were plunged into darkness, without so much as an emergency lamp burning. Below, red light rose up from the assembly floor like the glow of an actual forge. Gusts of hot air, stirred by industrial grade arc torches blew against his faceplate. A rustle of iron links, musical and cold, chimed from the deep shadows high above the floor.
Hundreds of chains had been suspended from the assembly building's ceiling, twisting and clinking together in
the restless air. Each chain, more than fifty metres in length, had been strung with dozens of hooks, and on each hook hung a fresh corpse. Nemiel saw the bodies of Tanagran Dragoons, skitarii - even the mangled bodies of dead Praetorians - along with the smaller figures of tech-adepts and half-mechanical magi. Their corpses had been riddled by bullets or torn apart by energy bolts, sliced open by power claws or crushed by mechanical fists, and their fluids leaked from them in a steady, dripping rain onto the hulls of the enormous vehicles below.
There were six of them, Nemiel saw. Their chassis were so wide that they could only be arrayed in a single file that stretched from one end of the assembly building to the other. Their armoured hulls were supported by dual sets of treads on each of the vehicle's flanks, with a sloped front that rose like a sheer-sided hillock more than two storeys high. Void shield generators studded the vehicle's sides, along with automated quad-laser and mega-bolter emplacements, but Nemiel scarcely noticed them. His gaze was drawn to the enormous cannon built into the centreline of the vehicle's hull. A complicated series of hoists and giant braces surrounding the cannon's barrel indicated that it was meant to be elevated and fired like a conventional artillery piece. The aft section of each vehicle was segmented like the body of a giant insect, and appeared to be even more heavily armoured than the rest of the hull.
'What in the Emperor's name are those things?' Kohl hissed. It was the first time Nemiel had ever heard the sergeant taken aback.
Techmarine Askelon carefully eased into a crouch beside them. His eyes widened as he saw the machines on the assembly floor. 'Siege guns,' he said, his voice tinged with awe, 'but far larger than any I've ever seen before. Those look like macro cannons, fitted to a custom hull.' He pointed to the nearest vehicle. 'See those dual treads? Those aren't part of a contiguous drive train. They are distinct drive units, similar in size and power the ones used on Baneblade super-heavy tanks. There are three to a side, and that's just to form the foundation for each vehicle.'
Tech-adepts were crawling like ants over each of the war machines, working feverishly along the armoured hull beneath the rain of gore. Symbols had been scrawled in blood at regular intervals along each machine's flank, but Nemiel couldn't make them out at such a distance. The Redemptor noticed that he vehicle closest to them had a large, open hatch on the top deck, to the right of the huge gun. 'What do you make of that?' he said, pointing to the two tech-adepts working in the well beneath the hatchway.
Askelon leaned slightly forward, peering intently at the opening. His eyes widened. 'It's an MIU interface chamber,' he said, 'A neural interface link, much like we employ on our Titans. It looks like they're refurbishing the control leads and making it ready for use.'
'So a single operator could control one of these behemoths?' Nemiel said.
The Techmarine nodded. 'Of course. They're big, but far less demanding than a bipedal Titan,' he replied. 'And the MIU makes it nearly impossible for them to be used if captured.'
Nemiel nodded grimly, his gaze rising to the collection of corpses dangling in the air before them. 'Now we know what happened to the Dragoons covering the southern approach,' he said, his voice thick with revulsion. 'Not to mention a good many of the forge's own personnel. Magos Archoi is a madman. This whole thing smacks of some obscene, superstitious ritual. How could someone like Horus Lupercal be connected to such debased behaviour?' Memories of the foul things he'd witnessed at Sarosh rose unbidden in Nemiel's mind. He forced them aside with an effort of will and a savage shake of his head.
Kohl tore his gaze away from the repellent sight and caught a glimpse of movement on the assembly floor. 'Here comes the high priest himself,' he growled, pointing to the narrow lane at the right of the parked war machines.
Nemiel straightened, craning his head around to see Magos Archoi walking down the line of vehicles. A pair of tech-adepts followed a discreet distance behind the magos, their hands tucked into their sleeves, while a knot of four uniformed men dogged Archoi's heels and studied the siege guns critically. One of the men was conferring with the magos, speaking to him in urgent tones. It took a moment for Nemiel to recognise the uniform he wore.
'15th Hesperan Lancers,' he murmured. 'Assigned to Horus's 53rd Expeditionary Fleet. It looks like some of the rebels stayed behind when their ground forces left the planet. They must have been meeting with that traitor Archoi and arranging delivery of the machines when we arrived.'
'And they've been biding their time ever since, waiting for the right opportunity,' Kohl snarled. 'That damned magos has embedded his warriors into every one of our combat units. We've got to warn the primarch or we may well have a massacre on our hands!'
At just that moment, Brother Vardus leaned out from the stairwell entrance. 'Movement on the stairs!' he hissed, 'coming from above and below.'
Kohl stared back at Vardus. 'Above and below simultaneously?'
Vardus nodded. 'They're moving quietly. Might be a pair of patrols.'
Suddenly, Askelon pointed across the cavernous space. 'I can see movement on the opposite gantry-way!' he said quietly. 'They're carrying something.'
Nemiel felt the hairs on the back of his neck go up. He looked down at the assembly room floor. Magos Archoi was standing there, surrounded by a circle of bemused rebels. The traitor's hooded head was tilted upwards, looking directly at him.
'They know we're here!' he cried, drawing his crozius from his belt. 'It's a trap!'
Lasgun fire erupted from the gantry-way on the opposite side of the building; red bolts hissed through the air, gouging craters from the permacrete wall in a string of sharp thunderclaps. A heavy bolter began to hammer away, spitting tracers across the intervening space in a series of measured bursts. Rounds struck many of the hanging chains, splitting their links and dumping their grisly cargo to the ground.
Nemiel fired a burst in the direction of the heavy bolter and activated his vox-bead. 'Invincible Reason, this is Brother Nemiel!' he cried. 'Can you read me?' He was answered with a rising screech of static. The Redemptor went through a score of frequencies and got the same result. Archoi's traitors were jamming the vox-channels.
Fire erupted from the stairwell behind Nemiel. Autoguns clattered and lasguns spat bursts of light at Marthes and Vardus, who responded with a brace of fragmentation grenades. Marthes levelled his meltagun down the stairs and fired a howling blast, then ducked out onto the gangway. 'There's a platoon of skitarii coming up the stairs!' he shouted.
Dark figures were rushing at them along the gangway from the far side of the building, firing bursts of lasgun fire as they advanced. Kohl and Ephrial exchanged fire with them, dropping several with well-aimed shots. A burst of heavy bolter fire answered them, stitching the two Astartes with a stream of shells. Both warriors staggered beneath the hits, but their armour turned aside the blows.
'Marthes! Put a shot on that gangway!' Nemiel yelled as he leaned over the thin metal rail and levelled his pistol at Magos Archoi. The traitor didn't even flinch as the Redemptor laid his aiming point at the centre of the darkness beneath his hood and let off a burst. The shells flew straight and true - and detonated harmlessly against a force field just a few scant centimetres from their target. The officers with the magos drew laspistols and returned fire, striking Nemiel once in the leg and abdomen.
Marthes shouldered his way onto the catwalk and fired his meltagun at the distant heavy bolter. The microwave burst struck the weapon and the gangway beneath it and superheated the metal in a split second, vaporising them in a fierce concussion and hurling burning skitarii to the assembly floor below.
'We're cut off!' Kohl shouted as he picked off another of the charging skitarii. 'Where do we go from here?'
Nemiel glared down at Archoi. Several metres away, one of the burning skitarii had become entangled in one of the chains on the way down, and now he thrashed and twisted in the air as the flames consumed him. On impulse, he bolstered his pistol. 'Follow me!' he said, then put a foot onto the rail and leapt into space.
The thin metal of the railing bent beneath his full weight, throwing him off balance, but his leap carried him far enough to reach one of the grisly, corpse-strewn chains. He grabbed hold with one hand and slid partway down its length before the slippery metal snaked out of his hands. Nemiel fell the remaining few metres and landed atop the lead siege gun. A tech-adept rose up beside him, raising a crackling arc-torch, but he may as well have been moving in slow motion. The Astartes smashed the traitor aside with a sweep of his crozius and began to run along the downward-sloping hull towards Archoi and the rebel officers.
'For the Lion!' he roared, raising the crozius aquilum high as he launched himself at the traitors.

In the 200th year of the Emperor's Great Crusade
General Morten shifted uncomfortably in the shuttle's oversized jump seat and tried to conceal the scowl on his face by pretending to study the view beyond the small window at his left. 'If I could perhaps get some idea of what it is you're looking for, I could arrange for a presentation from the garrison's senior officers.'
'That would defeat the purpose of the inspection,' Zahariel replied from his seat across the shuttle's passenger cabin. 'In fact, it would be best if the troops never knew I was there.'
'Very well,' Morten rasped, though Zahariel could see that his weathered face was still troubled. The Terran officer stared out the window for a moment more, debating what to say next. After a moment, he drew a deep breath and said, 'You asked me to inspect the troops at Northwilds to provide a cover for your own activities.'
'That's right,' Zahariel admitted. He didn't want to lie to the man any more than he had to. 'We'll part ways once the shuttle lands, and it's likely I won't be returning with you back to Aldurukh.' He spread his hands. 'I regret that I can't be any more candid, but this is Legion business. I'm sure you understand.'
