‘This is what I am referring to, master astropath,’ Vydel told him, without the suggestion of annoyance or inconvenience de Zut’s actions might have provoked. ‘Such wilful behaviour necessitates monitoring. I expected more of your kind. That was my mistake — after all, you are flesh and flesh is weak.’ The logi turned to his auspexmechanic. ‘Tollec, I want scan coverage, augur arrays and vox-monitoring intensified by forty per cent in line of sight quadrants. Particularly those occupied by Mechanicus contingents. Without filters, we might have emitted some optical or energy signature of our position.’
‘Scanning,’ the auspexmechanic said.
‘I understand why our surveillance needs to remain hidden from the enemy,’ de Zut acknowledged. ‘But your own people and priesthood? You’ve let them just die up to now anyway. Soon there won’t be anyone left to detect your presence.’
‘Master de Zut,’ Vydel said. ‘Are you familiar with our Third Law of Universal Variance?’
‘He will not comprehend,’ Autegra Ziegl said with confidence.
‘It is called the Bystander Paradox,’ Vydel continued, ‘and it states that whatever the Machine God’s servant observes, he affects. The magos metallurgicus’ involvement in an experiment might threaten to change its chemical outcome. An alien life form might behave differently under the gaze of a magos biologis than it would in its natural environment. A patient might stifle pain or embarrassing symptoms in the presence of a magos physic. You see, this signum-station is under strict orders — from the Fabricator General himself. Covertly observe. Record. Document. Do not interact. That is our solemn responsibility. And it is your solemn responsibility to send the sum total of our data and observations back to Mars.’
‘Solemn responsibility?’ the astropath repeated back. ‘What about our responsibility to those people?’
‘Their loss has been weighed and measured against future gains,’ Vydel replied.
‘And what of the losses on other worlds?’ de Zut spat back morosely. ‘While you coldly catalogue the slaughter of the Machine God’s servants, what of the mortis-cries of the dozen Imperial worlds I have intercepted? Mortis-cries of dying billions that I am bound by ancient decrees of my own order to report on, but that your surveillance protocols forbid?’
‘I calculate that to be a burden, master astropath,’ Lutron Vydel said. ‘But a necessary one. We cannot allow enemies — xenos or domestic — to learn of our surveillance. I understand that the mortis-cries might have tested you…’
‘These deaths are but data to you,’ de Zut said grimly. ‘You can close your blast screens so that you might avoid looking down on your losses. I have no such screen. I live each and every one: in here,’ the astropath said, slapping his palm against his temple.
‘I repeat,’ Vydel said, ‘we acknowledge the burden of such mortis-cries.’
‘And of the astrotelepathic distress calls to have reached us?’ de Zut interrupted. ‘What of the living, priest? Thirsk’s World? Aguilarn Tertius? Eidolica? The Verge Worlds? Fifty-One Xerxi? Port Sanctus? Undine? What of those we could save by breaking your precious Law of Universal Variance? Those who might be saved by others, if you only allow me to pass on their communications? We might be the only ones to have intercepted such calls for assistance.’
‘Out protocols are clear,’ Vydel said, unaffected by the astropath’s entreaties. ‘We are authorised to send one communication. One communication containing our evidence and findings. Observations of enemy conquest strategies, the workings of xenos technologies and the relative successes or failures of victim-worlds to repel invasions. One communication signalling the signum-station’s readiness for extraction and redeployment. These billions you feel for do not perish in vain. The Fabricator General will learn much from their annihilation.’
De Zut pushed himself back into the corner of the compartment, defeated by the cold logic of the tech-priests. Unclipping herself from her observation cradle, Autegra Ziegl allowed herself to drift upwards. Reaching out, she depressed the ceiling plunger, initiating the hydraulic closure of the port blast screen. She had no words of comfort for the astropath. Such capacity had long been surgically sliced from what was left of her organic brain, but she watched de Zut with brazen curiosity as he shook his head and took a long, hard drink from his suckle-flask.
‘I don’t understand you,’ he mouthed before again returning to the zero-gravity teat on the flask.
Ziegl turned to her notatio logi master.
‘Perhaps we should send the intelligence package now,’ she said.
Kelso Tollec turned his ocular-quad on the lexmechanic. ‘What of the data-loss? The analytical deficiencies?’
‘We would be failing both our Fabricator General and the Omnissiah,’ Erhlen Ohmnio said, his cheerful face-mask unchanged.
