Ragnar drew a bead on the daemon, which met his fierce gaze with one of his own. Yellowing teeth were revealed by its wide grin. “You wouldn’t…” it said cheerfully.

  Ragnar pulled the trigger and sent shell after shell streaking towards the daemon. One went into its head; three more went into its stomach. Botchulaz’s face crumpled inwards like a rolled up piece of paper. The shells sank without trace in the rippling folds of flab around his midriff. For a moment, Ragnar thought he might have done the thing some harm, but then the face sprang back into its normal shape — and then there was sound like a cork being pulled from a bottle, as the bolter shells were expelled from its flesh.

  “That hurt, a little,” it said in a pained voice. A horrible coughing sound began deep in its throat and for a moment Ragnar thought that perhaps he had damaged the monster after all. It bent forward, clutching its midriff where the bullets had gone in. A spew of vile stuff vomited from its mouth. Ragnar watched as the foul stuff bubbled downwards, engulfing the dying Gul. Even as Ragnar watched in disgust and horror, it filled the dying man’s wounds, closing them, and began to spread outwards over his flesh, leaving a blotched mouldy crust as it went.

  Gul gasped and shook like a man in the terminal stage of a dreadful fever. Then the shaking stopped and his whole body seemed to swell. His muscles ballooned out and his skin took on a sick greenish yellow tinge. Weird lights blazed within his eyes and he rose to his feet, fingers flexed like the talons of a hawk.

  “There we go,” said Botchulaz. “One good turn deserves another, that sort of thing.”

  Karah Isaan seemed to snap out of her trance. She yelled a fierce chant and raised her arms high above her head. A wave of white-hot psychic energy flowed out from her towards the daemon. A wall of searing fire enveloped Botchulaz and made his outline shimmer and dance. The daemon’s skin seemed to bubble and pop and for a moment, Ragnar thought the inquisitor might actually succeed in banishing it. Then the plague daemon’s outline congealed. It turned towards Karah and seemed to belch forth a tidal wave of energy of its own. Thousands of serpents of sickly green and yellow light entwined around her, encasing her form. She gave one long moan of agony, her skin suddenly blotched and discoloured and then she fell motionless onto the ground. Botchulaz stood there, steam rising from his skin as it knitted back together. He nodded amiably to himself, checked all his limbs to make sure they were intact, looked around and laughed pleasantly.

  “Well, it’s been fun, but I mustn’t dawdle. I have some business to attend to. I’m sure Gul will see to your deaths.”

  Ragnar watched in astonishment as a web of green and yellow light erupted from the plague daemon’s body. The air was suddenly filled with a sense of vast energies unleashed. The walls of the pyramid began to change colour. Ragnar knew this did not bode well for anybody on the surface of Aerius, but he did not really see what he could do about it right now.

  Gul was looking less and less healthy. His whole form slumped forward now, as if the flesh had partially melted. His fingers were extruding long talons. Massive boils were erupting through the crust around his body. There was a smell similar to putrefaction but even more sickly sweet in the air.

  “I am immortal,” he said.

  “We’ll bloody well see about that,” Sven yelled, leaping forward. Ragnar moved to join him.

  CHAPTER FOURTEEN

  A dozen things happened at once. The Blood Claws, Sergeant Hakon and the inquisitors all sprang into action. Writhing figures began to emerge from the vile carpet of muck caking the floor, whole bodies pulling themselves out, like swimmers emerging from the sea. They were vaguely humanoid, resembling smaller, less distinct versions of Botchulaz. Their heads were featureless blanks save where two sightless eyes had been poked in them. Their bodies had a fluid boneless quality. From their stink Ragnar could tell they had been created from snot, mucus and other daemonic excreta.

  Something snared his ankle, and looking down he saw a smiling face looking up at him. It seemed to have been carved from the floor but Ragnar knew full well it had not been there moments before. It leered at him with a crazed daemonic mirth which echoed Botchulaz’s.

  He kicked out with his leg, tearing the arm free from the ground. The fingers remained glued to his ankle and the whole form continued to emerge from the sludge. Bolters sounded all around as more bolts tore into Gul and the vile things the daemon had summoned. Ragnar heard the strange sucking sound once more as the shells bit home. They seemed to have no effect on the creatures. Ragnar found this to be hardly surprising. They were boneless, had no internal organs, and were animated only by dark sorcery. They would not succumb to wounds that would have felled a normal man.

  Gul laughed insanely, inspecting his altered flesh, capering with glee. “Now, servants of the False Emperor,” he said. “You will most assuredly die.”

  Ragnar shifted his leg but the grip strengthened and the snot thing’s arm lengthened. He felt the constriction increase, and to his horror saw that the ceramite was starting to give way in places. He lashed out with his chainsword and severed his captor’s arm at the shoulder. The blades screamed and tore and then cut right through. The arm came away and he was able to move.

  Looking around he saw that more and more of the eerie figures were pulling themselves from the floor. His battle-brothers blasted them with bolter fire but their flesh parted and knitted together again. He saw Sven lash out with a chainsword and chop off a head. It rolled free, was picked up by another shambling monstrosity of snot and mucus, which attached the head to its own chest. Gul stood in the centre of it all, encased in his blotched carapace, and howled with crazed mirth. Even as Ragnar watched one of the hideous figures reached out. Its arms stretched and a spray of its own disgusting slime smashed into Inquisitor Sternberg’s face. Ragnar wondered what possible harm this would do, until he saw streams of pus emerge through the inquisitor’s eyeballs. A moment later, under the extreme pressure of the vile fluid that had been forced into it, his head ripped apart.

  For a brief moment, Ragnar imagined the inquisitor’s last moments, worms of diseased plasma wriggling through the mush of his brain, and tendrils of foulness extruding down his throat into his stomach, choking off all air. Ragnar glanced over at Sergeant Hakon and knew from the veteran’s gritted teeth expression that the old Space Wolf was thinking along the same lines.

  It was time to get out of here. Ragnar picked up Karah’s unconscious form and threw it over his shoulder. Carving a green path through the knee-deep slime, he made for the exit of the chamber. Seeing him go, Gul drew his pistol and aimed it. His movements were slow and his hand trembled like that of a man with the ague but Ragnar knew it would not matter. All it would take was one shot.

  He dived forward, hoping that presenting a moving target might throw off the Nurgle worshipper’s aim. A bolt pistol shell churned the floor behind him. Ragnar kept moving, offering up a prayer to Russ and the All-Father. He heard the other Blood Claws shouting war cries as they, too, began to retreat from the room.

  Vile hands tugged his ankles, slowing him down. A terrible slurping sounded every time he raised his feet from the floor. It was like being trapped in a well-remembered nightmare, one in which deadly foes pursued him, and he was unable to make any headway in his escape.

  He heard another shot ring out and half-expected to feel a sudden agonising blast of pain in his chest. None came. He turned his head and saw that Sergeant Hakon had blasted Gul aside, and was now trying to fight his way clear of the mucus beasts emerging from the walls and floors. Ragnar wanted to go to his aid but some instinct warned him that it was imperative that he get Karah to safety. Perhaps the psyker would have some idea as to how to contain the plague daemon and its minions. He was certain of one thing: he did not.

  He breathed a sigh of relief as he saw Strybjorn and Sven move to the sergeant’s aid. They lopped off inhuman limbs with their chainswords, and then pulled Hakon to safety through the door. Ragnar glanced around in panic, wonderin
g what had become of Nils. Back in the heart of the room was a humanoid figure, completely encased in hardening goo. Even as he watched, more and more greenish figures threw themselves on it, and the struggling stopped.

  In a moment, all that remained was Nils’s outline, encased in hardened green stuff. Horror filled Ragnar. This was an abomination, and one against which there seemed to be no defence. Normal weapons appeared to have no effect against these creatures. Their soft, magically animated forms were impervious even to bolter shells, and simply knitted together again when struck with chainsword blades. It was like fighting with trolls, only worse; even trolls had not engendered this level of horror in him.

  “Go! Go!” Sergeant Hakon ordered. “There is nothing we can do for him now.”

  Ragnar wanted to stay, to at least try, but he could see the sense of the sergeant’s words. By staying they would only guarantee themselves a horrible death, one that was in no sense heroic. A sacrifice that would not help the teeming millions on the planet’s surface who would soon fall victim to the daemon.

  At least the things were slow moving. If they ran, he and his companions should be able to outpace them. He wondered what had happened to Gul. He had caught no sight of the traitor since Hakon had shot him. If there was any justice, Ragnar thought, he would be drowning in the mucus that covered the floor. Somehow he doubted they were going to be that lucky.

  Making sure Karah’s slight, lifeless form was secure on his shoulder, he began to trot back the way they had come, following the scent trail they had left on the way in. Behind him, echoing footsteps told him his remaining battle-brothers were on his trail.

  They emerged from the pyramid into night and an ominous silence. Ragnar wondered what had happened. Surely everyone could not be dead already. The daemon’s powers could not possibly be so virulent, could they? But how could he know what the thing was capable of? How could he measure the abilities of a being that had managed to stay alive in the heart of the Black Pyramid for millennia and which was capable of the dark magic he had just witnessed. Its powers far and away dwarfed those of Madox, the sorcerer-warrior of the Thousand Sons he had killed back on Fenris, and who was his only previous experience of the fell terrors of Chaos sorcery. Perhaps Botchulaz could indeed bring this world to its knees. Perhaps he had already done so. Ragnar had no way of knowing.

  He glanced around, out into the mist and silence. The patterns of tiny lights on the starscrapers glowed in the distance. Overhead he could see the running lanterns of aircars and descending spaceships. Behind him a strange greenish yellow glow suffused the surface of the pyramid. It pulsed eerily, and even as he watched the shimmering light seemed to separate itself from the structure, coalesce into a cloud and drift off into the night air. Thousands upon thousands of misty tendrils extended themselves outwards, a manifestation of a dark sorcery he could not quite comprehend. He was sure it boded no good for the inhabitants of Aerius.

  As he watched, the lights along the side of the Black Pyramid flickered and reassembled themselves into a new pattern. Ragnar could have sworn that for a brief instant he saw the leering face of the plague-thing looking down on them. Moments later, he was convinced that the face was itself made up of thousands upon thousands of smaller versions of Botchulaz, all capering and prancing and posturing. Even as he watched, liquid began to coalesce on the side of the pyramid. Droplets of green slimy sweat seemed to ooze from me very stone. It became apparent to Ragnar that whatever magic the eldar had used to imprison Botchulaz, it was no longer working.

  He realised that he himself was not feeling too good. His head felt light and sweat was pouring from his brow. He stifled a sneeze and realised that he was rapidly becoming feverish, ill in a way he had not been since he first became a Space Marine. Not even his altered physique was immune to the vile contagion created by the daemon, Botchulaz. All he could do now was pray to Russ and the Emperor that he was strong enough to resist the illness.

  It occurred to him then that if the disease was now strong enough to affect even Space Marines, it must be a terrible scourge indeed for ordinary mortals.

  “Smell that,” he heard Sven say. Ragnar sniffed the air and realised what his battle-brother meant. There was an odd taint to the night air which had not been there before. His nostrils seemed to tingle.

  “Vile sorcery,” Sergeant Hakon said. “Of the worst sort.”

  “What are we going to do about it?” Strybjorn asked.

  Hakon looked at the unconscious figure of Karah. “We need to find out what is going on. What the daemon has planned.”

  “I think that is just about to become obvious,” Sven said, pointing at the crowd of sickly figures which lay around the square. Ragnar’s foreboding increased as the eerie mystical reek intensified, swathing them in an almost tangible cloud. It was like the smell of sewage mingled with rotting flesh, only greatly intensified and a thousand times worse. The unhealthy mob had begun to moan and writhe. A few of them were starting to clamber unsteadily to their feet. They did not look as if they had recovered, though. If anything they looked worse. Their faces were pale. Pustules erupted all over their bodies. Their movements had a terrible slowness, like those of old men in the last stages of some terminal illness. Their flesh had an odd greenish yellow tint. Their sweat looked more like mucus than any normal body fluid, and gave their flesh a loathsome, nausea-inducing sheen. A strange greenish glow had entered their eyes, a sorcerous light that burned dimly beneath the rheum which crusted their eyeballs. Ragnar sensed the flow of alien energies around and through them. He knew now that they had passed beyond being human, and had fallen under the evil spell of the plague daemon.

  As if to confirm this, the first of the newly arisen plague victims turned towards the Blood Claws. It opened its mouth and let out an eerie sound, half shriek, half gurgle; a noise that made Ragnar think of a man drowning in the mucus that filled his lungs and throat. Slowly the infected man shambled towards them, arms outstretched, mouth agape, eyes blazing.

  Ragnar looked at his companions. He was not frightened. Compared to what they had just escaped in the pyramid these few corrupted souls were nothing. Then, in a moment, true realisation dawned, and what he was seeing became suddenly quietly terrifying. Across this world were millions of plague-infected mortals. If all of them, or even some, were turned into Nurgle’s creatures by this disease then the Plague Lord would soon have an enormous army under his sway. Worse than that, if the pestilence were to spread off world, soon systems, even entire segmenta might fall to him. Was it possible that the monstrous being was really this powerful? Truly, if it were so, then this was a threat not merely to the world of Aerius but to the whole Imperium! Despite himself, his respect for the dark powers of Botchulaz increased.

  “Perhaps we should return to the ship and get Inquisitor Isaan some treatment,” Sven suggested, looking at her recumbent form with concern.

  “No!” Ragnar said suddenly. All eyes turned to him. “If she is infected, if we are infected, all we will do is spread this contagion to the Light of Truth. Who knows where it might go from there?”

  “Ragnar speaks the truth,” Hakon agreed. “We must keep this place quarantined at all costs!”

  The sergeant spoke into the comm-net, relaying details of their situation to the ship, telling them to broadcast an interdiction order to all vessels in the system, and informing them to request the presence of an Imperial battlefleet to contain the threat. Ragnar saw the sense of this, but wondered what good it would do. By the time a fleet could get here, the damage would be done.

  Ragnar glanced back at the crowd. They were beginning to surround the Space Marines and their comrades. Ragnar was not sure what they hoped to accomplish, unarmed against armoured and well-equipped troops. As he watched, though, the crowd shambled forward, arms outstretched, fingers extended like talons. He was reluctant to open fire on these pitiful victims of Botchulaz’s daemonic machinations. They were, after all, the people he was sworn to protect, who their mission
had been intended to save.

  “Fire at will!” Sergeant Hakon said. “These people are beyond saving. They are no longer human, merely vessels of evil.”

  He matched his action to his words and opened fire. Bolter shells blasted through the chest of the first unfortunate, sending him tumbling back into the crowd. It did not even slow his fellow plague victims down: they shambled forward mindlessly, intent on pulling down Ragnar and his comrades. Ragnar realised that they might just possibly manage it too, by sheer weight of numbers. He reached for a grenade and lobbed it into the mass of bodies. The explosion tore them apart, sending blood and body fluids and internal organs spraying everywhere.

  Lasgun beams and bolter shells smashed into the walls beside him. Now he saw what was happening. There was no way through the press of bodies. There were too many of them, and some of them were armed. They could not fight their way clear. By sheer weight of numbers the plague victims were forcing them back into the pyramid.

  Karah stirred. When she spoke, her voice was weak but her words were clear and distinct. “Leaving here will do no good. The daemon is… tapping into the power of the pyramid itself, using the energies that once trapped him to fuel his sorcery. We must… stop him here and now, or we will not stop him at all. We must go back in there… and finish this…”

  At least she’s still alive, he thought and snapped off a shot into the oncoming crowd. It spoke with one voice, roaring and gurgling, and in that eerie cry, Ragnar thought he heard an obscene echo of the plague daemon’s mirth.

  “Let’s move!” Hakon yelled; his keen senses had obviously picked up her words. He raced back into the pyramid. Within heartbeats, the Blood Claws had followed him. Behind them, the mob howled and gurgled sickly, leaving Ragnar wondering what sort of hell they had found themselves dropped into.

  Around them the blackness of the ancient eldar pyramid closed in once more.
