Unfortunately for the Mosdva, the Tyrathca were more aggressive, a trait which came from their herd ancestry and its consequent territorial disputes, which in turn led to the breeding of the vassal castes, especially the soldiers. With their copied technology, greater size and larger numbers, they swiftly became the dominant of the two species.
This situation could well have spelt extinction for the Mosdva. Their settlements were being put under considerable pressure by the Tyrathca expansion. Then Mosdva astronomers discovered their star was about to expand into a red giant.
For a race whose thoughts operated on an abstract level, the knowledge of certain extinction in 1,300 years’ time would be devastating enough; for the Tyrathca, to whom a fact was immediate, it was intolerable. Racial survival provided a unifying motivator which enabled them to swiftly consolidate their domination of the planet. For the second time in their existence, the Mosdva were effectively enslaved. First they were used to devise a scheme whereby some if not all the Tyrathca could survive the star’s expansion. They came up with the arkship concept which would guarantee ultimate racial survival, with habitable asteroids sheltering the remainder of the population which couldn’t be evacuated. Secondly, they were made to implement it.
With their smaller bodies, greater dexterity, and higher intelligence, they made excellent astronauts—unlike the Tyrathca themselves. Mosdva technical expertise was adapted and utilized to capture asteroids and shunt them into orbit around Mastrit-PJ, where they were hollowed out and converted into arkships. The arkship building phase lasted for seven centuries, in which time 1,037 were built and launched.
After this, with the star’s growing instability wrecking the planet’s fragile ecology, Mastrit-PJ’s massive space manufacturing capability was switched to adapting asteroids into habitats. The asteroids chosen were orbiting more than a quarter of a billion kilometres from the star, putting them outside the predicted expansion photosphere. As this operation was far simpler than changing asteroids into giant starships, over seven thousand were created in just two centuries. Unlike the arkships which were immediately lost to the Tyrathca upon completion, building the asteroid habitats was a near exponential growth process, as new habitats used their industrial capacity to prepare further asteroids.
A thousand years after the project began, the planet had become uninhabitable, and was completely abandoned.
No Mosdva were ever carried on an arkship, the vessels were used exclusively by the Tyrathca. As soon as they had finished building one, the Mosdva were moved on to the next.
However, they couldn’t be excluded from the asteroid habitats without a policy of complete genocide. The Tyrathca tolerated them, knowing that their own numbers were constantly rising, necessitating an ongoing construction programme. And with the exact conditions of the star’s expansion unknowable, they would need Mosdva technical ability to adapt the asteroid habitats to the environment of the swollen photosphere.
When Mastrit-PJ’s star expanded, its diameter was larger than predicted, as was its radiant heat output. New, larger thermal dissipation systems had to be constructed for the asteroid habitats, and quickly. As a consequence, the habitats became even more engineering-dependent, which began the gradual shift of political power. Only Tyrathca breeders were capable of any meaningful technological activity, making all but the builder, housekeeper, and farmer vassal castes redundant. Their soldier caste was now bred purely to keep the Mosdva in line.
The revolution didn’t happen all at once, but rather over a thousand year period, starting ten thousand years earlier. The asteroid habitats initially formed a cohesive one-nation grouping after the expansion. But the scarcity of mass in the form of unused asteroids to mine forced the Tyrathca to revert to their original clannish state of competition. As the number of unused asteroids declined, wars were fought over the remainder. Each asteroid habitat reverted to complete autonomy.
After that, the rise of the Mosdva to supremacy was inevitable. They controlled the habitat machinery, and industrial facilities, a power they discovered which enabled them to dictate their terms to the Tyrathca.
Under this new order, the asteroid habitats gradually banded together politically and physically. As they did, new design concepts were enacted, bringing the old Mosdva dictum of sustainability to the fore, enabling them to maximise their use of dwindling mass resources. Life support sections outside the spun-gravity biospheres were constructed.
First they were little more than adjuncts to the gridwork which held the clustered asteroid habitats together; transport and transfer tubes, eliminating the wasteful need for airlocks and vessels. But the Mosdva, with their climbing-adept limb arrangement and natural agility, found they adapted well to the freefall environment inside them. Only the Tyrathca needed gravity and the associated complex engineering to maintain the rotating biospheres. More freefall segments were constructed and added to the clusters, hydroponics and industrial sections first; which led to their technicians spending more and more time in freefall.
Living sections followed quickly. The era of the diskcities began.
“And the Tyrathca?” Joshua asked. “Are they still here?”
“We do not keep them any more,” Quantook-LOU said. “They are no longer our masters.”
“I congratulate you on ridding yourselves of them. The Confederation has always found them difficult to deal with.”
“But we are not difficult, I hope. And the dominion of Anthi-CL is on the edge of Tojolt-HI. That makes us rich in mass, more than any other. We are good trading partners for you, Captain Joshua Calvert.”
“How does being on the edge of Tojolt-HI make you richer than other dominions?”
“Is that not obvious? All ships have to dock at the edge. All mass flows through us.”
“Oh, classic,” Ruben said. “The rim dominions are the diskcity harbourmasters, they can charge what they like to allow cargo through. They’ve probably got some kind of political alliance between themselves to put the squeeze on the central dominions.”
“A minimum fee?” Joshua asked.
“Most likely. It puts us in a good position. Everything travels through them; QED, they must have good communications with all the other dominions. They should be able to find us a copy of the almanac file if it still exists.”
“Okay.” Joshua checked his neural nanonics time function. They’d been in the diskcity for nine hours. “I thank you for your hospitality, Quantook-LOU. My crew and I would like to return to our ship now. We have gathered enough information to see where our respective interests lie, so we’ll start reviewing what items and information we’ve brought with us which will bring about the most beneficial exchange for both of us.”
“As you wish. How long will this review process take?”
“Only a few hours. I look forward to returning, and the start of true negotiations between us.”
“As do I. Our resources will be marshalled to cope with your demands. Perhaps then I could visit your ship?”
“You would be an honoured guest, Quantook-LOU.”
Ten Mosdva formed the entourage to see them back to the MSV. It had been left untouched, though Ashly and Sarha who’d been monitoring its status, reported it had been bombarded by every conceivable active sensor sweep.
As soon as they were back through Lady Mac’s decontam procedure, Joshua ordered the SII suit to withdraw, giving a huge sigh as his skin was exposed to air again. “Jesus, I thought that Quantook character would go on forever about how wonderful his people are. Don’t they ever sleep?”
“Probably not,” Parker said. “As a general rule, sleep evolves from a planetary day-night cycle; they don’t have that here any more. I suspect they have slow periods, but no actual sleep.”
“Ah well, that’s one weakness we’ll have to concede to them. I need a meal, a gel wipe, and some time in the cocoon. It’s been a long day.”
“I concur,” Syrinx said. “The ELINT satellites are approaching operational range,
which may or may not give us useful information on the dominions. We also need to evaluate what we’ve heard today, and I’d like us all fresh for that. We’ll reconvene in six hours to see what the satellites have found and discuss the next stage.”
Joshua managed three hours in the cocoon before he woke. He stared at the cabin wall for fifteen minutes before acknowledging he’d need to put a somnolence program into primary if he wanted to sleep again. He hated doing that.
Liol, Monica, Alkad, and Dahybi were already in the small galley when he air-swam through the hatch. They gave him varying sympathetic looks which he acknowledged ruefully.
“We’ve been talking to Syrinx and Cacus,” Monica said. She shrugged at Joshua; he’d paused in the act of filling his tea sachet from the water nozzle to raise an eyebrow. “Not just us that’s restless. Anyway, they’ve located another seven diskcities.”
Joshua datavised the flight computer for a general communication link and said good morning to the Oenone’s crew.
“The Mosdva empire appears to be quite extensive,” Syrinx told him.
“Judging by the distribution of diskcities we’ve seen so far, that early estimate needs to be revised upwards. Fair enough if we believe there were seven thousand asteroid habitats to begin with. Kempster and Renato have also been scanning further out from the photosphere. So far they haven’t located a single lump of rock within twenty degrees of the ecliptic. Quantook-LOU was telling the truth when he said there was a desperate struggle for mass after the stellar expansion. Every spare gram must have been incorporated into the diskcities.”
“Quantook-LOU didn’t say struggle,” Joshua said. “He said wars, plural.”
“Which he blamed squarely on the Tyrathca,” Alkad said.
Joshua gave the physicist a bleak look. She didn’t say much, but her comments were normally pretty valid. “You think the Mosdva took control earlier than that?”
“We can never know exactly what this star system’s history is, but I would think it likely that the Mosdva started their revolt right after the star’s expansion phase. That would be when the Tyrathca were most dependant on them. Everything else we’ve been told does tend to paint them in an unusually generous light. An oppressed people struggle to regain their long-lost freedom. Please. History is always written by the good guys.”
“I did gloss over some of our less endearing traits,” Joshua said.
“That’s human nature.”
“You should have stung Quantook-LOU’s office space with some nanonic bugs,” Liol said. “I’d love to hear what’s being said in there right now.”
“Too big a risk,” Monica said. “If they found them, at worst they could interpret it as a hostile act; and even if they were diplomatic about it, we would have handed them a whole new technology.”
“I don’t think that leaves us much to worry about,” Liol said. “The Confederation isn’t about to be invaded by Mosdva, it’s the Tyrathca we have to worry about.”
“Enough,” Joshua said. He shifted round to make room for a sleepy unshaven Ashly who was drifting into the galley. “Look, we’ve just about got everyone up now anyway, we’d best convene and thrash out what we’re going to do next.”
There was one more discovery before the meeting started. Joshua was finishing his breakfast when Beaulieu datavised a curt message requesting him to access Lady Mac’s sensor suite. “I’ve located a Mosdva ship,” the cosmonik said.
“At last,” Liol said eagerly. He closed his eyes and accessed the image.
Beaulieu hadn’t activated any visual enhancement programs to counter the redness. All Joshua could make out was a big brilliant-white shape gliding up towards a rendezvous with Tojolt-HI—the same configuration as the ship already docked to the rim: five huge globes clumped round a drive unit and scoop. Except these globes were glowing a vivid purple-white, brighter than the photosphere.
“It surfaced twenty minutes ago,” Beaulieu datavised.
The cosmonik replayed the recording. Lady Mac’s sensors had detected a magnetic anomaly within the photosphere, hundreds of kilometres wide, the flux lines twisting into a dense wood-knot pattern. But it was moving faster than orbital velocity, and growing larger. Visual sensors started tracking it, showing the endless scarlet haze. At first it was as unruffled as a sea mist at dawn, then the impossible happened and long streaks of shadow rippled across the picture. They were actually folds in the gas. Something underneath was stirring the igneous hydrogen atoms, creating swirling currents in the calm envelope. A bright patch of white light started to shine up through the red plasma. The ship rose up smooth and clean through the outer layers of the photosphere, scoop first, pushing a vast bow wave of glowing ions ahead of it. Each of its five globes was shining as bright as a white dwarf star, radiating away enormous quantities of electromagnetic and thermal energy. Thick scarlet coronas avalanched from the lip of the scoop, purling gently all the way back down into the body of the red giant. The remainder of the nimbus was sucked down into the ship’s funnel, growing steadily brighter as it progressed, until it was consumed by a dazzling white flame burning brightly at the throat.
“The globes have been dimming since it surfaced,” Beaulieu said. “Their external temperature is dropping in concert.”
“Looks like you were right about it being a ramscoop, Josh,” Liol said cheerfully. “It’s got to be where they get their mass from now the asteroids have been consumed. Fancy that, mining the sun.”
“That thermal dump technology is damn impressive,” Sarha said. “It’s got to be superior to anything we have. Shedding heat while you’re inside a star. God!”
“Simply compressing and condensing photosphere hydrogen into a stable gaseous state wouldn’t generate that much heat,” Alkad said. “They must be fusing it, burning it down into helium, perhaps even all the way to carbon.”
“Christ, they must be desperate for mass.”
“The iron limit,” Joshua mused. “You can’t fuse atoms past iron without having to input energy. Every other reaction until that element generates energy.”
“Is that relevant?” Liol asked.
“Not sure. But it makes iron their gold equivalent. It can’t hurt knowing what they value most. It’s the trans-iron elements that they’ll be running out of.”
“The fact that they’ve resorted to this extraordinary method gives us some considerable leverage,” Samuel said. “We’ve seen little evidence of molecular engineering compounds in the diskcity structure. Our materials science will allow them to exploit mass far more efficiently than they do currently. Every innovation we bring has the potential for inflicting vast change upon them.”
“This is what we have to decide,” Syrinx said. “Liol, have the ELINT satellites revealed anything that might help us?”
“Not really. They’re holding station a thousand kilometres above the darkside now, which gives us excellent coverage. It’s pretty much what we observed as we flew in: trains moving about and very little else. Oh, we picked up a couple of nasty-looking atmospheric vents. The tubes must have ruptured. There were bodies in the gas stream.”
“They must fight a constant maintenance battle against structural fatigue,” Oxley said. “That’s a lot of surface area to cover.”
“Everything’s relative,” Sarha said. “There’s a lot of Mosdva to cover it.”
“I wonder how inter-dependant the dominions are,” Parker said. “For all Quantook-LOU says about driving a hard bargain on the cargo and mass which Anthi-CL sends to the inner dominions, they have to ensure supplies are preserved. Without fresh material, the tubes would decay. The inner dominions would react strongly to such a threat, I imagine.”
“We’ve confirmed eighty dead areas across Tojolt-HI,” Beaulieu said.
“They amount to just under thirteen per cent of the total.”
“So much? That would tend to indicate a society in decline, possibly even a decadent one.”
“Individual dominions might fall,” Rube
n said. “But overall their society remains intact. Face it, the Confederation has inhabited worlds that don’t exactly thrive, yet some of our cultures are positively vibrant. And I find it significant that none of the rim sections are dead.”
“The other major source of external activity is based around those dead sections,” Liol said. “It looks like major repair and reconstruction work. Those dominions certainly aren’t decadent, they’re busy expanding into their old neighbours’ territory.”
“I can accept they’re socially comparable to us,” Syrinx said. “So based on that assumption, do we offer them ZTT technology?”
“In exchange for a ten-thousand-year-old almanac?” Joshua said. “You’ve got to be kidding. Quantook-LOU is smart, he’ll know there’s something very wrong about that. I’d suggest we build in an exchange of astronometrical data and records along with whatever commercial trade deal we can put together. After all, they’ve never seen what lies on the other side of the nebula. If we offer them the ability to break free of Tyrathca-dominated space they’ll need to know what’s out there.”
“I’ve told you,” Ashly said. “ZTT isn’t a way out.”
“Not for the proles,” Liol said. “But the leadership might take it for their families, or clans, or members of whatever cause they rally round. And it’s the leadership we have to deal with.”
“Is that the kind of legacy we really want to leave behind us?” Peter Adul asked quietly. “The opportunity for interstellar conflict and internal strife?”
“Don’t get all moral on me,” Liol said. “Not you. We can’t afford those kind of ethics. It’s our goddamn species on the brink here. I’m prepared to do whatever it takes.”
