The Beast Arises

And then what? Thane almost asked, but stopped himself. It would not do to imply a lack of trust. Instead, he said, ‘That would amuse the orks greatly. I don’t propose to give them that satisfaction. I will do everything in my power to avoid bloodshed. You have my word on that.’

Aloysian’s nod was slight. ‘I believe you, Chapter Master. But will the Mechanicus make the same effort?’

‘You are better placed to answer. What do you think?’

‘I don’t know,’ Aloysian said. ‘The greater the secret possessed by Urquidex, the more desperate the priests of Mars will be to keep it to themselves.’

‘And the more vital it becomes for us to learn that secret.’

‘Precisely. So where, Chapter Master, do you see the way to avoid war?’

Honour’s Spear shook harder, hammered by the Martian wind storms. Thane accepted the interruption gratefully. He had no answer for Aloysian.

The gunship broke through the smog-choked clouds of Mars. Thane looked through the viewing block and beheld the Pavonis Mons complex reaching up for him. Somewhere in that vastness, Urquidex was being held. The volcano was almost four hundred kilometres wide, and monolithic Mechanicus architecture covered its surface completely. The slope of Pavonis Mons was a gentle one, taking hundreds of kilometres to rise fourteen, but the colossal edifices and manufactoria turned it into a twisting, spiked, aggressive prominence. The fifty-kilometre caldera sprouted a cluster of gigantic chimneys, each the size of an Imperial Navy battle cruiser. They vomited the waste of Mechanicus industry into the sky, a more noxious and violent eruption than the volcano itself had ever produced.

As Honour’s Spear descended, the details of the structures became clear. Towers that Thane had taken for manufactoria were single machines, thousands of metres high. Some rotated around each other in a slow, majestic dance. Others were the pistoning ribs of an inconceivably gigantic beast. They connected to the monstrous buttresses and vaults of the manufactoria proper, of the habs for tens of millions of servants of the Omnissiah, and of laboratoria the size of hives.

‘How will we find our quarry in that?’ Abbas asked.

‘The terrain is not unknown to me,’ Aloysian said quietly.

‘I hope we will not have to seek him,’ said Thane. ‘I hope he will be brought to us.’

‘A faint hope,’ said Aloysian.

Thane made no answer. Below, the immensity of the Pavonis Mons complex stretched its iron claws upwards.

The gunships and transports came down at the edge of the space port at the base of the south face of the mountain. Alarms wailed from the towers of the port and the spires of the complex spilling off the slope and onto the surrounding plain. The Thunderhawks disgorged troops and vehicles, then rose to fly overwatch for the company. Thane organised the deployment with an eye to a maximum display of power. The battle-brothers marched at the head of the column. The Rhinos, empty except for their drivers, brought up the rear. In between came the tanks: Land Raiders, Predators, Vindicators and Whirlwinds. There was the strength here to flatten a city, and there was more to come. But Pavonis Mons was more than a city. Thane hoped the initial threat would be enough. He would escalate it as required, though he hoped he would not have to do so.

But Aloysian’s logic was sound.

The column rumbled away from the space port. It followed the main transport avenue running from the space port to the Tharsis Gate. Embedded in the immense walls encircling the base of the volcano, the Tharsis Gate was the primary access point to the Pavonis Mons complex, both above and below the surface of Mars.

Cathedral warehouses and cloud-piercing manufactoria lined the avenue’s sides. Webs of monorail tubes ran overhead, forcing the Thunderhawks higher. Ochre dust blew down the canyons between the structures. A sea of Mechanicus serfs and monotasked servitors parted ahead of the Fists Exemplar, a thousand thousand pedestrians and transports funnelling into cavernous cargo and work bays, or melting into narrower streets held in perpetual night by the shadows of the towers. From the jutting rise of the complex came an angry red glow. Cataracts of molten ore fell hundreds of metres from spouts to receptacles. Thane gazed at what he had come to bend to his will: a great mechanism, too large for the eye to encompass, too powerful for even its operators to comprehend. A mountain of metal and stone rumbled and groaned.

And it cried out.

The sirens whooped, Mars warning of invaders, Mars preparing for war. At the other end of the avenue, where it opened up into the kilometres-wide Square of the Infinite Reach before the Tharsis Gate, Thane saw the Mechanicus forces gather, and then move.

‘Where did they come from?’ Raalega asked. The Tharsis Gate was shut fast.
