Kelbor-Hal accepted the data wafer, surprised to feel a tremulous thrill of excitement at the thought of what he might learn from its contents. It was a thin sliver of metal, fragile and insignificant, yet capable of containing every written work on Terra a hundred times over.
No sooner had his metallic fingers touched the wafer than his haptic receptors read the data in a flow of electrons, and he knew that Regulus spoke the truth. Genocidal wars had been fought for information less valuable than was contained on this wafer. Millions had died in search of technology worth a fraction of its value.
In centuries past, the Mechanicum had waged war on the tribes of Terra, despatching expeditionary forces to humanity's birth world to plunder forgotten vaults of ancient citadels and wrest the buried secrets of the third planet's ancient technology from those who did not even know it was there, let alone how to use it.
The Emperor had built his world on the bones of this long-buried science, and, unwilling to share it, had fought the soldiers of Mars and hurled them back to the red planet before travelling to Mars in the guise of the Omnissiah and a peacemaker, albeit a peacemaker who came at the head of an army of conquest.
The peace that was offered was illusory, a conceit designed to conceal a darker truth.
The Emperor offered peace with one hand while keeping a dagger behind his back with the other. In reality, the Emperor's offer was an ultimatum.
Join with me or I will simply take what I need from you.
Faced with a choice that was no choice at all, Kelbor-Hal had been forced to bargain away the autonomy of Mars and become a vassal planet of Terra.
'These are great gifts indeed,' said Kelbor-Hal. 'Given freely?'
Regulus bowed his head. 'As always, my master, you cut to the heart of matters with the precision of a laser. No, such gifts are not given freely, they come with a price.'
'A price?' spat Chrom, the glare of his eyes flaring in response. 'The Warmaster seeks to exact more from us? When we have already pledged him the strength of our forges!'
'You seek to back out of the bargain with the Warmaster?' demanded Regulus. 'We knew great things would be asked of us, but the measure of us how we react to these challenges. Great reward comes only with great risk.'
Kelbor-Hal nodded, the blank face of his face mask slipping into the bland countenance of a conciliator. 'Affirmarion: Regulus is correct; we have come too far to balk at paying a price for such things. Already we and our allies strike at those without the vision to see that Horus Lupercal is the true master of mankind.'
'The things we have done,' said Adept Malevolus. 'The schemes we have set in motion. We have come too far and committed too much to back away from the fire simply because we fear its heat, Lukas. The destruction of Maximal's reactor, the death of Adept Ravachol… were they for nothing?'
Chastened from two sides, Chrom bowed his head and said, 'Very well, what does the Warmaster ask?'
Regulus said, 'That when it comes to strike, we guarantee to have Mars firmly under our control. The dissident factions must be quashed so that the forces of the Warmaster may launch his bid for supremacy without fear of counterattack. Any factions loyal to Terra must be brought to heel or destroyed before the Warmaster's forces reach the Solar System.'
'He asks much of us, Regulus,' said Kelbor-Hal. 'Why should we not believe we would merely be swapping one autocrat for another?'
'Horus Lupercal pledges to return the Martian Empire to its former glory,' said Regulus, with the practiced ease of a statesman. 'Further, he swears to withdraw any non-Mechanicum forces from the forge worlds.'
Ambassador Melgator stepped forward, his black, mail-fringed cloak rustling on the smooth floor of the observation chamber. The ambassador rarely spoke when any but he and the object of his attention could hear him, and Kelbor-Hal eagerly anticipated his words.
'With respect, Adept Regulus,' said Melgator. 'The Warmaster, blessed be his name, has already asked us for a great deal and we have delivered. Materiel and weapons are priority tasked to expeditions he favours and delayed to those not aligned with him. He now asks more of us, and are these, admittedly valuable, STCs all he promises us in return? What else does he offer as proof of his continued friendship?'
Regulus nodded, and Kelbor-Hal saw that he had anticipated the question, the prepared answer flowing smoothly from his vocabulator.
'A shrewd question, ambassador,' said Regulus. 'Horus Lupercal has given me an answer that I believe will satisfy you.'
'And that is?' asked Malevolus.
Regulus seemed to swell within his robes. 'The Warmaster will lift all restrictions on research into the forbidden technologies. To that end, I bring the protocols that will unlock the Vaults of Moravec.'
A heavy silence descended on the gathered adepts, as the weight of the Warmaster's offer hung in the air like a promise too good to be true.
