The perfect, mechanical repetition. It might as well have been a recording. Thane knew it wasn’t. Perhaps all Van Auken had left was escalation. As did Thane.
‘Chapter Master,’ Aloysian voxed. ‘Is one magos worth the cost we are facing?’
‘Would you abandon our mission?’ Thane glanced to his left. The Master of the Forge was in the front line, a visible reminder to the Mechanicus of the fused alliance between Mars and Terra.
‘I am not suggesting dereliction,’ said Aloysian. ‘I am weighing the consequences. Which would cause more damage to the Imperium — the loss of Urquidex, or war on Mars?’
‘Your logic is faulty, Master Aloysian. The information Urquidex possesses may outweigh any disaster here.’
‘We don’t know.’
‘No. But we know our orders. We know our oaths of moment.’
Aloysian was silent.
‘I appreciate your situation,’ Thane said. ‘But…’ He trailed off and waited.
Aloysian grunted. It was a very human sound, a rare expression of emotion from the Techmarine. ‘I know what I am,’ he said. ‘I am Adeptus Astartes. I am an Exemplar. My duty is clear, Chapter Master.’
‘I have no doubt it is. I will still spare us war if it is at all possible.’
Aloysian shook his head. ‘It will not be.’
Still, I will act as though it is, Thane thought. ‘This confrontation is senseless,’ he boomed to the Martian warriors. ‘We all serve the same Imperium. We all serve the Emperor. Will you turn your back on the Imperium in its moment of peril? I will not believe this of the priests of Mars. And now we will pass.’
He began to walk forwards. ‘A steady advance,’ he ordered the company. ‘Slow. Give them time to move back. Weapons at ready, but do not address targets. We go forwards, we do not stop, but we do not fire. Acknowledge.’
Clicks came back to him over the vox.
The Fists Exemplar advanced. The space between the forces shrank.
Van Auken watched the vid-screens and hololith tables. He was in a command centre below the surface, near the core of Pavonis Mons. The screens covered the walls. Feeds updated themselves every second. Targeting data from the Dunecrawlers changed as they tracked gunships and tanks. An auspex-mechanic sat before each column of screens, summarising and condensing the slivers of situation into bursts of code, their signals running through the cogitators and into the Artisan Primus’ mechadendrites plugged into the master console. Moment to moment, he had a near-total awareness of the entire territory running from the space port to the Tharsis Gate.
‘They are advancing,’ transmitted Sicarian Princeps Tynora 7-Galliax.
‘I am aware of this development.’
‘Understood, Artisan Primus. The delay between the situational change and your orders prompted my erroneous conclusion.’
It was possible to discern a veiled insult in her explanation. Van Auken ignored it. ‘Do not allow them to pass.’
‘What means are authorised?’
‘The mass of our forces. Do not engage.’
‘Unpredictable contingencies raise the likelihood of combat to near-certainty.’
‘The Adeptus Astartes are highly disciplined. The possibilities of intemperate error are concomitantly reduced.’
‘Accepted without optimism. Query: is the risk an efficient use of resources?’
‘We have not yet ascertained the degree of the heretic Urquidex’s knowledge. Once the full extent of the damage has been ascertained, he will be mind-wiped. The Adeptus Astartes may claim him at that point. Until then, his threat outweighs all others. Premise: the Fists Exemplar are also fully conscious of the consequences of war. Their data is also incomplete. They can conceive of no escape for Terra from the orks. Theorem: conflict here while orks are over Terra will be avoided as an absolute evil.’
‘Counter-hypothesis,’ said 7-Galliax. ‘Lacking alternatives, they will stop at nothing.’
‘Possibility evaluated and dismissed,’ Van Auken said.
He watched the two forces come together. With all the variables clamouring for his attention, there was no room for doubt.
The Mechanicus closed ranks. There were only a few metres between Thane and the line of skitarii.
‘They don’t want to let us through,’ said Abbas.
‘We shall have to convince them otherwise,’ replied Thane
The solid wall of Fists Exemplar closed the gap. The Adeptus Astartes towered over the skitarii vanguard troops. The armour of these warriors was heavy by Mechanicus standards — they were more substantial and less insectoid than many of their comrades. They were still dwarfed by the Space Marines.
The Fists Exemplar did not pause. They pressed forwards, steady and inexorable as the tide. Thane kept his bolter against his chest, barrel angled up. He was not attacking, simply advancing. Skitarii rifles were pointed at him. He pushed into the barrel of the vanguard warrior before him. He took another step, forcing the other to choose between taking a step back, firing, or engaging in melee combat. The skitarius stepped back. So did the rest of the line. The Fists Exemplar moved forwards again.
