‘Look at that,’ said Lukar, pointing to one of the ceramite slabs ahead. ‘Switch to thermal.’
Alpharius did so, a film of red falling over his vision as his armour’s auto-senses tracked through the frequencies to the infra-red end of the spectrum. Behind the panel Lukar had pointed at he could see a tracery of brighter lines.
‘Power cables,’ said Alpharius. ‘Sergeant?’
‘I see it,’ replied Dor, holding up his hand to signal the halt. ‘Commander, we have some kind of power conduit ahead.’
‘Understood.’ Agapito’s reply was immediate, his voice tense. ‘Await orders.’
‘Proceed thirty metres, Sergeant Dor.’ The primarch’s deep voice cut across the vox. ‘You will see a sealed door ahead of you. Wait by the door for further instructions.’
‘Affirmative, lord,’ replied Dor, waving his hand to set the squad moving again. ‘Keep an eye out for weapons systems.’
They had advanced only another five metres when a panel in the ceiling hinged open and a multi-barrelled gun dropped into view. Lukar was the first to react, unleashing a salvo from his bolter into the opening, the explosive shells tearing through a nest of cables. Sparks showered down and the weapon wilted on its mechanical arm, twitching fitfully.
‘If that’s the worst this place has to offer, this shouldn’t be too hard,’ said Lukar.
As if in response to his bravado, there was a shout of alarm from behind the squad, followed immediately by the crack of a laser bolt.
‘Eyes front!’ snapped Dor. ‘Not our problem. Keep advancing.’
The chatter of bolter fire and the distinctive crackle of a plasma gun echoed along the passageway as the squad continued on. As Corax had told them, they came upon a chamber a few metres wider than the corridor, bare except for a door in the opposite wall. The portal was slightly recessed into the ceramite, made of the same material. Alpharius could see no sign of a handle or lock, though his thermal vision showed several power cables leading into the sill around the door.
‘We just wait here?’ asked Velps. He pulled a melta-bomb from his belt and held it up. ‘This’ll burn through that door in no time.’
‘Don’t you do anything,’ said Dor, warning Velps back with a raised hand as the legionary took a step across the room.
Alpharius looked around the square chamber. Other than its dimensions there was nothing to mark it out from the passage that had led to it. The featurelessness of the corridor, the perfect uniformity of it, unsettled him. He was an Alpha Legionnaire and intimately knew the disorientating power of anonymity. It would be very easy to get lost in such a place, and Alpharius had no intention of ending his life in this bland but deadly warren of passages and rooms.
‘Perhaps we should mark our progress somehow, in case we get turned around,’ he suggested.
‘What do you mean?’ asked Dor.
Alpharius drew out his combat blade and etched a cross into the ceramite wall to his left.
‘If we see that again, we know we’ve come in a circle,’ he said.
They waited for several minutes. Alpharius looked back down the corridor and saw the other half of the squad a dozen metres behind, still in the corridor. The heat from the power packs of the following legionaries was building up, distorting the air with a haze. To Alpharius’s thermal vision the vents on the backpacks of the other legionaries were bright white.
‘Commander, we are giving off a high heat signature,’ said Alpharius. ‘The primarch said that the defence systems had thermal registers.’
‘Good point,’ replied Agapito. ‘All squads, set cooling systems to minimum. Reduce heat signatures.’
‘Negative, do not adjust heat signatures.’ Corax’s tone was quiet but terse. Alpharius realised the primarch had to be monitoring every squad communication, a considerable mental feat. ‘I need you to trigger the thermal sensors if necessary. Team two will shortly be in position. Their progress will trigger the first transformation. The door ahead of you will open in two minutes. Stand ready.’
IN THE ENTRY chamber, Corax had his eyes closed, the totality of his mind focused on picturing the mechanism of the Labyrinth and the positions of his squads. He had blocked out all input save for the constant narration that streamed across the command network into the communications bead in his ear.
Like a burglar examining the most complicated lock ever devised, the primarch imagined the interplay of revolving rooms, rising bridges, closing doorways and collapsing arches. The three forces had already begun to divide, combat squads directed through new openings to trigger the next transformation of the maze. With each random change, Corax’s plan evolved and solidified, as possible avenues of approach opened or were shut. He could not predict every movement of the Labyrinth, but he could respond swiftly to each development. The timing of each move had to be precise, and he snapped out orders in a clipped voice, redirecting the combat squads to where they were needed.
He blotted out the sound of gunfire and the rumble of mighty engines and immense pistons. He ignored the curses and warnings of his warriors. His sole purpose was the unpicking of the lock.
Twenty-three minutes and one hundred and seventeen metres after first entering the Labyrinth, the Raven Guard suffered a casualty. A legionary under Agapito’s command was struck in the chest by a laser bolt from an automated turret that had risen from the floor.
‘We have no Apothecary,’ the sergeant reported. ‘Mathan looks in a bad way.’
‘You must leave him behind, Sergeant Cannor,’ Corax replied quickly. ‘We will return for him later. Move the rest of the squad up to the second archway on your left. The doorway ahead of you will be closing in seven seconds.’
‘Mathan is still alive, barely. He needs treatment.’
‘You have your orders,’ Corax said coldly. The gene-tech – the rebirth of the Raven Guard – was a prize greater than any individual life. There could be no delays. The Labyrinth would already be moving towards its next configuration. To falter would be to fail, and that would make every life lost a vain sacrifice. ‘Move your squad now.’
‘Confirmed, Lord Corax.’
Distracted by the event, the primarch had almost missed an opportunity to get Agapito’s lead squad across a bridge that might ascend into the heights when Arcatus’s men entered the chamber ahead of them. Corax made a swift calculation and judged there still to be time enough for the crossing.
THE RAMP AHEAD seemed innocuous enough to Arhuld Dain, special weapons bearer of Squad Seven, though Lord Corax had warned the squad to approach with caution. The ferrocrete causeway rose ten metres above the floor of the chamber, leading to a circular door that looked like a ship’s airlock. Dain looked up and saw a similar opening directly above, and what appeared to be the rungs of a ladder leading from one of the walls across the ceiling.
‘How would anybody get up there?’ he asked, adjusting his grip on his flamer as the five-man combat squad advanced towards the causeway.
‘I have no idea,’ replied Sergeant Caban. ‘Stay focused.’
With a loud hiss, the double doors through which the squad had entered slid shut behind them. Dain detected vibrations pulsing through the floor at the same time as a distinctive crackling came to his ears.
‘Wait!’ the legionary snapped, stopping in mid-stride. Sergeant Caban took another step onto the causeway before turning back.
‘What is…’ The sergeant’s voice trailed away as the whole chamber lurched, spinning quickly on its axis, spilling the squad into the air.
Dain felt himself go light, drifting away from the floor. The ceramite underfoot provided no purchase for the magnogrips of his boots and he floated away, the rest of the squad lifting up around him. Sergeant Caban slipped past him, propelled through the air by his last step, gently inverting as he slowly glided towards the wall behind Dain.
The Raven Guard found themselves suspended about three metres above the floor, which had become a wall. Dain tried to twist towards the rungs of th
e ladder, whose purpose became clear. Angling his flamer, he fired a short burst, using it as a crude propellant to send him flying towards the ladder.
‘What are you doing?’ demanded Caban. The sergeant came to halt against the far wall, one hand outstretched to stop himself.
Dain reached out with his left hand, flailing for the closest rung. His fingers closed around the metal.
The crackling noise increased in pitch, becoming a pulsing whine. Dain looked around, trying to find the source. The ladder was thrumming with energy between his fingers. Realising his error he let go and tried to push himself away with his legs.
Lightning arced from the ladder, coruscating across Dain’s armour, earthing through exposed cabling around his midriff. The muscles in his abdomen tightened as electricity surged through the legionary, his spasm causing him to kick out, hurling himself across the room as spark erupted from his armour and flames burst from melting seals and blown circuits. He could feel his flesh charring and cracking, the pain muted by a sudden rush of anaesthetic compounds produced by his body. Dain’s jaw felt as if it had been welded shut while agony flared through his head.
Spinning madly, he blacked out, his last vision that of the room turning again, his companions plummeting towards the new floor.
‘INCOMING ORDERS,’ SAID Dor, motioning with his bolter for Marko and Alpharius to move through the doorway ahead. ‘Distributing on squad channel.’
Alpharius and Marko edged through the opening with their weapons ready. They found themselves on the edge of a large, vaulted chamber. Ten metres from them, the floor dropped away into a dark chasm, a natural fault in the strata of the mountain. With the thermal sight of his suit, Alpharius could see the telltale glint of power cables and weapons positions on the ceiling above, not yet activated.
‘In thirty-two seconds, a bridge will descend to your position,’ came Corax’s voice, relayed through Sergeant Dor’s vox-unit. ‘You will have forty-three seconds to cross that bridge.’
‘There are seven weapons turrets,’ Marko reported. ‘Irregularly spaced. We only have clear lines of sight to three of them from this side. We will have to get onto the bridge before we can see the others.’
‘No cover,’ added Alpharius. ‘We’ll be targets on a shooting range.’
‘Blind grenades,’ replied Corax. ‘They will disable the units for twenty seconds.’
‘Still not enough time, lord,’ said Dor. ‘The gorge must be at least two hundred and fifty metres wide.’
‘Sprint, sergeant,’ came the primarch’s clipped response.
Alpharius was about to protest but held his tongue, as if the order had been given by his own primarch. The others seemed willing to trust in Corax’s judgement and he could not afford to show any dissent.
‘I’ll go first,’ he said. ‘Marko, can you target that second turret on the right?’
‘From the edge of the chasm, yes,’ said Marko.
‘Wait!’ snapped Dor, as Alpharius readied a blind grenade from his belt. The Alpha Legionnaire froze in place.
The sergeant took a few steps past the pair, looking around.
‘Save it for when we reach the bridge,’ said Dor, lifting his bolter towards the darkness that hid the far side of the chamber. ‘We can take out these turrets before we cross.’
A deep rumbling reverberated around the cathedral-like hall, sending dust shaking down from jagged stalactites that had grown up around the heavily riveted girders that held back the weight of the ceiling. From a recess far above, a metal structure descended into view, swaying on dozens of chains each as wide as a legionary’s shoulders.
‘You have forty-three seconds.’ Corax’s voice was calm, almost emotionless.
Dor spat out a string of orders and the squad burst into action. Alpharius headed towards the metal pillars that marked where the bridge would fall. The clump of his boots activated a sensor and a turret directly above his head extruded from the metal of the ceiling. Lukar fired his bolter, shredding the gun’s casing in a storm of sparks.
Alpharius carried on, trusting to his squad to protect him as he primed the blind grenade in his fist. The whine of the multi-melta filled his ears for a split second before another turret disintegrated into a mist of molten metal that rained down on the Alpha Legionnaire’s armour.
With a thunderous clang, the bridge hit the braking pillars and rocked to a halt. Alpharius was already bounding along its length as it settled, his boots sending up flakes of rusting metal from the mesh of its floor.
‘Thirty-five seconds,’ Dor warned them, his words almost lost in another blaze of bolter fire, this time from Velps. Another turret burst into flames.
Alpharius ran across the bridge, blind grenade held ready, arms and legs pumping, his armour-assisted run covering three metres with every stride. He heard the clamour of the others following behind, and tensed, waiting for the distinctive snap of a las-bolt.
‘On the right, quadrant three!’ barked Dor. Alpharius did not look, but heard the sound of Velps behind him sliding to a halt. A red flash blazed from the gloom, melting through the bridge just a metre behind him. Velps’s bolter roared and the defence turret was silenced.
‘Grenade away!’ Alpharius bellowed, hurling the blind field detonator far ahead of him. The orb arced through the darkness, glinting ruddily as another turret opened fire, its blast scorching a line across Alpharius’s vision as it bit into the bridge decking just in front of him. The machines controlling the turret had adapted and anticipated his run; only the momentary pause to throw the grenade had saved Alpharius from a direct hit.
He bent forwards into a full sprint as the blind grenade erupted into life at the far end of the bridge, forming a whirling cloud of silvery particles and swirling forks of electromagnetic energy.
Again the system controlling the defences had evolved. The turrets were blinded, but whereas before they had ceased their fusillades, now they opened fire with a storm of bolts, flashing randomly around the chamber with a criss-cross of ruby beams. As a beam seared past his right shoulder, Alpharius almost cursed in his native tongue, the words stopped by his gritted teeth as he plunged into the storm of the blind field.
Clanking gears and hissing pistons sprang into life. The bridge lurched under Alpharius’s feet, almost sending him toppling over the low rail. The blind cloud raged around him, blotting out all of the data being fed through his armour’s auto-senses. In silence and blackness, Alpharius leapt, powering himself into the air.
It seemed to take an age for the legionary to land, swallowed up by the blind field, oblivious to the crackling las-bolts that were undoubtedly flaring all around him.
He landed with a heavy thud and almost lost his footing, coming down hard on one knee, the impact sending alarm signals through his suit. He surged to both feet and pressed on, trusting that the others were following him, trusting also that Corax was correct and there was an archway or open door ahead to provide sanctuary. The blind cloud was already collapsing, the chaff and distortive energies fluttering into the darkness.
Freed from the effects of the blind grenade, Alpharius’s comms and auto-senses sprang into life again. Las-fire blazed around him, sending up wisps of molten rock from the floor. There was no point trying to dodge the haphazard fusillade and he pressed on up the slightly sloping floor while his auto-senses shuddered. Patches of light swam across his eyes and a dull ringing sounded in his ears as the suit’s systems recovered from the blind field.
‘–igh and left,’ Dor was shouting as he emerged from the spreading miasma of disruptive energy. ‘High and left!’
Alpharius swung his bolter up to a firing position and saw through the infrared haze a flicker of the turret’s artificial eye blinking in the darkness. He fired three rounds, puncturing the casing of the gun position, sending shards of metal through the air.
‘Keep moving,’ Lukar said, slapping a hand to Alpharius’s shoulder as he ran past. Alpharius looked ahead and saw a blast door descending ove
r a yellow-lit opening.
The legionaries ducked under the closing portal in quick succession, armour clattering. Marko was the last in line, slightly slower due to the weight of his heavy weapon. A red beam of laser energy spat down from the ceiling and shattered the armour of his right leg. Twisting, Marko tried to fall under the closing door but fell short.
‘Leave him,’ Dor snapped.
Alpharius ignored the command and acted out of instinct, dropping his bolter to grab Marko’s backpack with both hands. He hauled with all of his strength, dragging the stricken legionary under the door moments before it slammed closed with a resounding crunch.
They were in a corridor much like those they had first encountered in the maze, with drab grey walls without markings. It curved away sharply to the right, the route ahead hidden after ten metres.
‘Sergeant Dor, report status.’ Corax’s voice was assured, confident that his warriors had succeeded.
Dor looked at the squad, the lenses of his helm glinting in the bright light that came from a single strip in the roof.
‘We’re through, Lord Corax,’ he reported. ‘Marko is hurt, though.’
‘Can he move?’ The question hung in the air while Marko pulled himself to his feet with Lukar’s aid. He hefted his multi-melta, checking the power cabling that linked it to his backpack.
‘I’m not staying here,’ Marko said, voice strained. ‘But don’t expect me to do any more running.’
‘He can move,’ Dor passed on the legionary’s assessment. ‘What are our orders?’
‘Continue along the passageway for thirty metres.’
‘Understood. We are advancing,’ Dor replied.
At that moment, something came around the bend in the passage, clanking and hissing. It was a strange mix of bipedal machine and small tank, with tracked feet of metal links, its main body shaped like a turret with two multi-barrelled cannons protruding menacingly from the front. Sensor discs and artificial eye lenses dotted a small module atop the machine.
