If there were minefields, no one had marked them and I found myself becoming more and more tense with every step I took. Macharius led us to a spot between the guard towers. His keen gaze scanned backwards and forwards and I knew that he was looking for sentries patrolling the open space between those towers. I could not see any, but that did not mean they were not there. Perhaps they were standing, smoking, behind one of the pillars that supported the wire. Perhaps they had already spotted us and were lying in wait, weapons ready to open fire as soon as we got within range. It’s astonishing the things that your mind comes up with in situations like this.

  We reached the edge of the wire and took up positions to cover Macharius in case anyone closed with us while he was cutting. He slashed through the wire with one sweep of the chainsword and then paused for a moment, listening.

  If any alarm had been given it was not audible to us, but that did not mean anything. Somewhere, in some distant control bunker perhaps, a red light was flashing and alarms had started to sound.

  Macharius gestured for Anton to go through. Anton did so and then the rest of us followed until only Macharius and I were left on the far side of the wire. I gestured for him to go ahead like some polite gentleman at the door of his club in the upper reaches of the hive. Macharius grinned and went through and I took a last look around to make sure that no one was creeping up on us from this side of the fence and then I followed him myself.

  We began to move across the plascrete plain, moving closer to the flyers that Macharius had already picked out. They were small local transport models of a variant I was not familiar with. They were armoured though and they had turrets, which might well prove useful, providing no one was already in them and ready to shoot us down. It all seemed to be going too well. I thought for a moment that the luck of Macharius or the Blessing of the Emperor shielded us still. It was Ivan, as usual, who had to spoil things by pointing out that this was not in fact the case.

  ‘Watch out,’ he said, indicating off towards the control bunkers of the airstrip with the barrel of his lasgun. I immediately saw what he meant. From out of the central bunker, a number of wheeled vehicles had emerged and were moving in our direction as fast as they could be driven. Either the alarm had been given or someone had spotted us and mustered the guards. It looked like we were going to have a fight on our hands and it was not a fight that we could win.

  ‘Run,’ said Macharius, moving towards the nearest of the flyers.

  I don’t think I have ever covered ground as quickly as I did then and I suspect that the same was the case for the others. Ground crew surrounded the flyer. They had been running checks on the systems and preparing the vehicle for flight. One of them looked at us and shouted something. Anton did not wait to see what would happen next. He pulled the trigger on his lasgun and burned the man down.

  I heard the roar of machine engines close behind us and turning I saw the enemy vehicles were almost upon us. I aimed my shotgun at one of the buggies. The huge balloon tyre exploded and the vehicle skidded into another buggy with a crash of metal on metal.

  Men screamed as they were crushed between the two. The others opened fire on us. We kept moving towards the flyer, shooting at the ground crew, even though they were not armed. None of us wanted one of them to get inside and disable the vehicle or even attempt a take-off before we got there. Sirens were sounding in the distance now and I could see the lights of more buggies coming closer.

  We were within the shadow of the flyer when the rest of buggies rolled to a stop and disgorged their cargo of armed men. I counted at least twenty of them, all of them in the uniforms of the local defence forces. One of them was a priest of the Angel of Fire. I suspected that they were in every important, strategic location, overseeing the local warriors in exactly the same way as our commissars oversaw us. At the sight of that red-robed heretic, my heart sank.

  The alarm had very definitely been given and if we did not manage to get away in this flyer, it was obvious that we were never going to manage to get away at all.

  Macharius had already leapt on board along with the inquisitor, and the others were following them up the loading ramp. Only the Understudy and myself were on the ground now. I pumped the shotgun and aimed at the priest and pulled the trigger. He saw what I was going to do and raised his arms in a gesture that I am sure had some cryptic, mystical significance. He never got to complete it before something took his head off. I looked around and saw Anna standing there with that huge gun in her hand.

  Whatever protected those heretic psykers from las-bolts clearly had no effect whatsoever against those high-calibre, sanctified slugs.

  The guards kept coming closer. I kept shooting and backing away up the ramp on the back of the flyer. Metal flexed under my feet even as las-fire melted the metal of the walkway. The smell reminded me of the factorum workshops of my youth with their casting forges and sacrosanct welding engines.

  The flyer began to move, taking off even with the loading bay open. I tumbled forwards and I felt the shotgun slip out of my grasp. I clutched it tight and then a claw-like hand grabbed my shoulder and pulled me backwards with such a jerk that I almost fell over. The Understudy had caught me and was dragging me inside.

  As ever, he ignored the shots of our enemies as if he simply could not see them. This time one of them hit him and I smelled burning cloth and burning flesh. He grunted but he did not scream and he kept pulling and I kept scrambling and then the loading bay ramp began to fold itself into flight position and the movement of its hydraulic systems tumbled us into the body of the aircraft.

  I heard strange sounds as the flyer’s systems creaked under the strain of the take-off: the sizzling sounds of melting paint and metal where las-fire impacted on the hull. Worse than that was the thunder of metal on metal as some sort of heavy weapon was brought to bear. The hull gave way as if an ogryn were hitting it with a sledgehammer. Dents appeared and the flyer began to wobble in the air as if the force of the shooting was driving us off course.

  I lay on the floor gasping and trying to calm my nerves. I have never minded being in a tank when it was under fire but there was something about being in an aircraft in similar circumstances that made me want to void myself with fear.

  I forced myself to stand upright despite the lurching of the aircraft. A loud scream echoed within the hull and I looked around quickly to see what had caused the panic. It was only Anton shrieking with pure pleasure, as if this was some sort of joyride and he was some sort of child. I fought down the urge to punch him and instead turned to face the Understudy.

  I wanted to take a look at his wound but he had already stripped away his officer’s jerkin and was inspecting the scorched skin beneath. It looked nasty. There was a huge blister that had burst and peeled away revealing the moist, sticky flesh beneath. I began to rummage through the emergency medical kit near the rear loading-bay door. Within a few moments I found what was needed and was spraying the damaged skin with synthi-flesh. It closed over the wound, filled with air bubbles and resembled nothing more than a large wart but it would protect the damaged flesh until it could heal. The Understudy nodded as if to thank me and then sat down and strapped himself in.

  I looked forwards and I could see that Macharius and Inquisitor Drake were within the cockpit, wrestling with controls. They seemed to be moving them at random and the flyer jumped all around the sky.

  Had they gone mad, I wondered?

  I looked at the porthole and realised that there was some semblance of sanity in what they were doing. Heavy bolter fire tracked our flight and sometimes impacted on the armoured hull. I could also see that there were other flyers coming in pursuit. I looked at Anton and Ivan and I said, ‘Can you two lazy bastards do something? Doesn’t this flying heap of junk have some turrets that you could be inside?’

  They looked at me as if I was speaking another language. If it had been a tank and if it had been on t
he ground they would have taken up position at once but outside the environment that they were familiar with, the idea had never occurred to them.

  ‘Why don’t you go bloody fly the thing?’ Anton asked.

  ‘I would but we already have two people doing that,’ I replied.

  ‘Well maybe you should take your own advice then!’ Rather than arguing with the idiot I decided to do just that. I found a ladder that led up to the topside turret and in a few seconds I was strapping myself in and chanting litanies that I hoped would activate the weapon.

  I ran through the invocation drills with my hands, pushing down the sacred spheres that I hoped would perform the same function as they did on a ground vehicle. I grabbed the handles of the weapon in exactly the same way as I would have grabbed the handles of a similar one in a tank. And then I leaned forwards and looked through the sight and got my first view of our surroundings and the things that pursued us.

  The exterior of the hive skimmed by below. Enormous towers rose like tall, narrow fungi from the side of a mossy hill. Industrial effluent ran down the terraces like lava down the side of a volcano. I could see the multi-coloured lights of the jewelled windows of the hab-blocks and vehicles going about their journeys below us. In the distance, a couple of similar flyers to the one that we were in pursued us. They were already shooting with heavy bolters.

  I put in a comm-net ear bead and listened but all I could hear was Macharius talking into the local system. ‘We need to take those down now,’ he said calmly. ‘If we don’t we’ll have other airborne swarming all over us in a few minutes.’

  I suspected that that was going to be the case anyway but now did not seem like the time to argue about it. Instead I concentrated on shooting and sent a stream of heavy bolter fire towards one of the oncoming flyers.

  It swerved to one side, an angry insect trying to avoid being swatted by a drunken man. I kept shooting and tracking it but it moved too fast for me and I had no skill with this weapon.

  It was luck more than anything else that destroyed my target flyer. As the pilot swerved to avoid my shot, one of his flyer’s stubby wings struck the side of a nearby building. Immediately, the flyer swerved out of control, tumbling end over end and wing over wing. The damage would not have destroyed it if the pilot had been able to regain control but he simply did not have time and his tumbling vehicle smashed into the side of another hab-block and exploded. Splinters of broken metal smashed the nearby windows. A gas jet within the building ignited, causing blowback. A trail of flame shot out of the side of the hab and I was very glad that I was not alongside when it happened.

  The other enemy flyer had gained altitude and was somewhere above us. I could tell by the bolter fire contrails coming down in the sky. Looking up I saw the vehicle’s running lights. I sat as far back in the seat as I could and the guns tilted upwards but they couldn’t elevate enough to get our pursuer into my sights. There was nothing I could do from the present angle. I spoke into the comm-net and said, ‘Take us up and I can get a second shot at the bastard.’ As an afterthought I added, ‘Sir.’

  I heard Macharius chuckle and we began to swing upwards. At the same time other turrets on our own craft opened fire and I guessed that Ivan and Anton had finally decided to join the party. All three of us managed to target the flyer but it was just as armoured as our own vehicle and it withstood the impact.

  The enemy weapons had found the range now and they kept shooting at us as we kept shooting at them. It was simply a case of which flyer’s armour gave out first or which of us found a weak spot in the other’s hull. I began to play my turret’s fire over the enemy flyer. The impact points sparked. Nothing gave way.

  We gained altitude and then suddenly, sickeningly, we flipped over and looped down behind the enemy. I dangled upside down in the turret, trying to stay focused. The other pilot panicked. He veered to one side. We kept shooting, hammering the vehicle with our fire. Macharius dived suddenly and brought us alongside. We kept firing, our bolter shots impacting all along the side. Macharius nudged the other flyer with the stubby wing of our vehicle, forcing it into a nearby wall. It smashed hard, hull breaking apart. Our fire finally took effect, hitting some vital internal part. The explosion turned the enemy flyer into a fireball.

  We cheered and flew on, racing over the hive exterior like a runaway rocket, staying low and dodging at speed between the buildings. I rotated my turret so I could look behind us to scan the sky for pursuit. I saw the running lights of hundreds of vehicles but nothing that looked as if it was coming for us.

  I offered up a prayer of thanks to the Emperor as I watched Irongrad recede into the distance. It loomed behind us like an impossibly vast mountain, covered in glittering contrails of light and lava. At its peak, the monstrous figure of the Angel of Fire loomed, fiery wings spread wide and illuminating the swirling multi-coloured clouds above it. I had a sense of an ominous terrifying presence growing where it stood.

  ‘What the hell is going on down there?’ I heard Anton ask.

  It took me long moments to see what he meant. On the vast industrial perimeter of the hive, it looked as if rivers of fire were boiling up from underground springs. The earth was cracking, buildings had tumbled. Pipes were broken. In a dozen places they vented flames. Ahead of us the wastelands were split by great fiery chasms. Lava bubbled forth, forming rivers and lakes. The flyer carried us closer. The sight was awesome. I was reminded of our original landing site. It looked as if a new lava sea was being born in front of us.

  ‘I don’t know,’ I said, ‘but I do not like it one little bit.’

  Once the city was well behind us, Macharius set the flyer down in the desert. He did not give any explanations. He merely picked a flat-topped mesa and landed. All of us climbed out and began to inspect the flyer and I understood why he had done so. The aircraft was enormously beaten up. In places the hull looked as if it was just about to fall apart. Somehow the general had nursed the flyer this far but I doubt that it would have gone much further.

  ‘Never an adept around when you want one,’ said Anton with his usual attempt at humour.

  ‘There are other things to worry about even if we can fly much further,’ said Macharius.

  ‘Sir?’ I asked.

  ‘If we get too close to our army we risk being shot down by our own air-cover. This is a heretic vehicle with heretic beacons and I doubt anyone will believe us if we tell them who we are.’

  ‘Bad security, anyway,’ Drake said. ‘If any enemy aircraft are in the area and intercept the call, they can kill you with one strike.’

  I looked out into the distance. A massive dust storm was moving across the desert, a monstrous, moving cloud that obscured everything in its way. It took me a second to realise it was no dust storm.

  ‘I think the point has just become moot,’ I said.

  Inside all those clouds of dust was a huge army. I could see the enormous shadowy shapes of Baneblades and Shadowswords, each a mobile fortress of plasteel and ceramite, each giving a sense of total invulnerability. All around them were thousands of Leman Russ battle tanks and even more Chimera armoured personnel carriers. Valkyries swarmed the air above them like a cloud of angry hornets. It looked like the Imperial Guard had decided to return to Irongrad in force. Macharius must have seen this from the cockpit. It was obviously why he had chosen this spot.

  ‘I think we have some trouble,’ said Anton. I immediately understood what he meant. Some of those Valkyries were descending towards us. Eagle-eyed pilots had spotted us and were coming to investigate. I prayed to the Emperor that they would ask questions first and shoot later. I was not entirely sure that I would do that under the circumstances but I hoped that the pilots might prove to be somewhat less aggressive.

  Macharius had already thought of that. An emergency flare arced skywards, set by the hands of the Lord High Commander himself. I immediately understood his thinking. If we were
scouts and spies we would not draw attention to ourselves like that, not unless we were very stupid, which is a possibility you can never rule out when dealing with some. I hoped the pilots would have more respect for our intelligence than that. I knew it would not be long before we found out.

  Soon a Valkyrie hovered in the air above us, weapons trained on us. We kept our hands in the air as a second airship descended and soldiers spilled out covering us with their lasguns.

  ‘Keep your hands in the air, and don’t make any sudden moves,’ said an officer.

  ‘Captain Argus, is that you?’ Macharius said. I was suddenly very glad of his talent for being able to remember people’s names. Captain Argus’s jaw dropped. He looked like a man who had just encountered a ghost, which is exactly what he thought he was seeing.

  ‘Lord High Commander Macharius?’ he said. He looked astonished, as if he could not quite believe what he was seeing.

  ‘In the flesh,’ Macharius said. ‘We talked when I decorated you after the Battle of Khalion.’

  As with so much that Macharius did, it was perfect. It let Captain Argus know that he was exactly who he said he was. No spy could have known a little detail like that. You could see the captain standing a little bit straighter as he came under the general’s eye. All of the other soldiers suddenly looked as if they were at attention. I am somewhat proud to report that they did not stop covering us with their weapons though.

  ‘And I must see General Sejanus at once,’ said Macharius. ‘There is much that needs to be done and very little time to do it in. This world is in the gravest danger and we are the only people that can save it.’

  It should have sounded utterly fantastic, completely implausible. But when Macharius said things like that, men jumped to obey. He strode forwards and no one pulled the trigger of a lasgun. They might have done if it was me or Anton or Ivan but they would not do it to him. Drake followed him and Anna then the Understudy. To my surprise, Macharius beckoned the rest of us forwards as well. ‘You’ve been my bodyguard this long,’ he said. ‘You can manage it for a bit longer.’
