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
“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
“The Mosdva empire appears to be quite extensive,” Syrinx told him. “Judging by the distribution of
