“How come they abandoned this?” she asked. “Why not rendezvous with an asteroid and use it as a ready-made base for their microgee industry?”
“Because of the upkeep,” Oski datavised back. “The whole thing is interdependent, you can’t just keep a life support ring going and dump the rest. And it’s big. Keeping it functioning would take too much effort for the level of return. They were much better off building smaller-scale asteroid habitation caverns from scratch.”
“Shame. At the very least the Tyrathca could have made a fortune selling it as a human tourist destination.”
“That’ll be that famous phlegmatism of theirs. They just don’t care about it.”
After five minutes they came to the first second-level cavern. A hemisphere two hundred metres high, the walls ribbed by bands of tubes.
There was a single huge machine in the centre, supported by ten three-metre-thick pipes that rose out of the ground to act as its legs.
Another ten pipes emerged from the top of the machine to vanish into the chamber’s apex. The team stood just inside the entrance, playing their suit beams over the metal beast. Its sides were fluted with long glass columns, tarnished on the inside with heat-blackened chrome. Valves, coils, relays, motors, intake grids, high-voltage transformers, and pumps protruded from the rest of the edifice like metallic warts.
“What in Christ’s name is that?” Renato asked.
“Access your file,” Oski told him. “It’s some kind of biological reactor. They bred a lot of organic compounds inside it.”
Renato walked over to one of the big pipes and took a look directly underneath the reactor’s formidable bulk. The casing had cracked as the arkship lost its heat, allowing ragged strings of some blue green compound to ooze out all over the base. They’d clotted in hanging webs before freezing solid. Smears and stains of other liquids were splattered across the floor.
“There’s something wrong with all of this,” Renato datavised.
“What do you mean?” Samuel asked.
“Just look at this thing.” The young astronomer slapped his hand against the pipe. Even in the rarefied atmosphere, the suit audio sensors could pick up a faint clang. “It’s, like … immortal. I can’t imagine anything else occupying this chamber since the day they left their star.
I know they’ll have rebuilt it a hundred times during the voyage. And I know they go for the brute strength engineering solutions. But I don’t understand how nothing can have changed in fifteen thousand years.
Nothing, for Christ’s sake. How can you draw a line across your technology and say we will never develop anything that goes beyond this?”
“You’ll be able to ask them soon,” Monica datavised. “Their ship will reach us in another ten minutes. Look, Renato, I know this is all fascinating, but we really don’t have the time. Okay?”
“Sure, I’m sorry. I just hate unsolved puzzles.”
“That’s what makes you a good scientist. And I’m glad you’re here to help us. Now, this is the corridor we want.” Monica left another sensor disk on one of the stolid pipes and started walking again. Renato took a last glance at the ancient reactor and followed her. The two serjeants brought up the rear.
“The Tyrathca ship is definitely docking,” Beaulieu said. “They’ve matched velocities with Tanjuntic-RI.”
“Bugger,” Joshua grunted. They were enjoying a slight lull in the three-dimensional chess game that was the high-orbit diversion. Lady Mac was accelerating at one gee, sliding over Hesperi-LN’s pole at a hundred and seventy-five thousand kilometres altitude. Eighteen combat wasps were arrowing in towards her from every direction, a classic englobing manoeuvre. The closest one would reach them in another four minutes. At least the hellhawk wasn’t a current factor. Syrinx confirmed they were still chasing the Stryla round the two moons.
“Liol, break the bad news to the team, will you?” Joshua concentrated on the starship’s systems schematic, ordering the flight computer to configure the hull for a jump. Somewhere near the back of his mind, almost in the subconscious, was a smiling astonishment that he could now be so confident about taking part in a space battle. Contrast his, and the crew’s, calm responses and performance today to the frantic shouting and adrenaline powered high-gee desperation above Lalonde, and it was as though they used to belong in an alternative universe. The major difference, of course, was that he’d initiated this, he was calling the shots.
“Dahybi?”
“Nodes charged and on line. Ready to jump, Captain.”
“Great. Let’s see how accurate we can be.” He cut the fusion drives and initiated the jump.
The watching Tyrathca saw the dangerous invader vanish from the middle of their combat wasp swarm. SD sensors picked up its emergence point simultaneously, fifty thousand kilometres from where it had jumped. Its fusion drive came on again, powering it back down towards the planet, presenting fresh danger to the population. The pursuing craft all changed course to resume their chase.
A crackling smog of hot ions splashed across the front of Tanjuntic-RI as the Tyrathca ship finished its approach manoeuvre. Electrical discharges flashed along the remnants of the superconductor grid, burning off the fragile surface molecules in scintillating spectral fountains. The pilot hadn’t bothered to rendezvous at a distance and nudge in towards the spaceport cone using secondary drives. Their flight vector was projected to bring them to a halt less than a kilometre from the arkship, completely disregarding the damage the fusion drives would inflict on the ancient vessel.
The ship was a typical Tyrathca inter-planetary craft, a simple cylinder a hundred and fifty metres wide, three hundred long. Unlike human designs which were built round a load-carrying gantry to which modules and capsules were attached as required, this had everything encased inside an aluminium hull. A basic, ugly workhorse of a ship, discoloured by years of exposure to the thermal and ultraviolet emissions of Hesperi-LN’s star. Four big rectangular hatches were spaced equidistantly round its front end, while five stumpy fusion rocket nozzles protruded from the rear.
When it finished its deceleration burn it was floating parallel to Tanjuntic-RI’s spaceport, two kilometres out. Small chemical rockets flared around its edges, brilliant sulphur yellow flames pushing the ship in towards the rotation axis. It started to turn at the same time, aligning its base towards the spaceport. The chemical rockets around its front end throttled up to maximum, and two fusion rockets ignited briefly. Their plasma plumes stabbed out, twin incandescent spears transfixing the centre of the spaceport. The burn didn’t last for more than a couple of seconds, nor was it particularly powerful. But the damage caused was immense. Metal and composite detonated into vapour, roaring out from the impact point.
It was too much for the enfeebled spaceport structure to withstand. The entire cone of stacked disks snapped off close to the base, tumbling away. Individual disks tore loose, spinning off in every direction, spewing fragments as they went. One disk actually collided with Tanjuntic-RI, crumpling as if it were made from paper before it started to rebound. All that was left of the spaceport’s support column was a shattered ten metre stub sticking out from the rock. It was rapidly eclipsed as the massive Tyrathca ship positioned itself directly overhead. Two hatches hinged open, and several dozen pale ovoid shapes were ejected. At first they drifted as aimlessly as thistledown in a zephyr, then puffs of gas erupted from small spouts around their crests, and they started to fly in towards the broken end of the support column.
Hesperi-LN’s twin moons were not a hospitable location for spacecraft.
Their clashing gravity fields had drawn in a great deal of cosmic debris since their formation, and continued to do so. Dust, sand, and smaller motes were eventually liberated by the solar wind, light-pressure and high energy elementary particles blowing them back out towards the stars.
But the larger chunks remained. Pebbles, boulders, entire asteroids; once they’d fallen into a looping orbit, they were slowly hauled in over the millen
nia as the ever-changing gravity perturbed their new orbit.
Ultimately, they wound up at the central Lagrange point, poised equidistantly between the moons. It was a cluttered zone over a hundred kilometres across, visible from the surface of Hesperi-LN as a fuzzy grey patch. In composition, it mimicked a galaxy, with the largest asteroids clumped together at the centre, surrounded by a whirl of smaller boulders and stony nuggets.
A place, then, where the use of combat wasps and energy beams was essentially impossible. You could stay within its fringes and observe your enemy waiting outside with impunity. Providing you could ward off the clouds of dark, high-velocity gravel swirling endlessly around the periphery of the Lagrange cluster.
Oenone’s attempts to pursue the hellhawk inside the cluster had come to nothing. After twenty minutes of dangerous slaloming and weaving, during which it gained barely a hundred metres on the contemptuous hellhawk, Syrinx had decided enough was enough. They were draining the energy cells at an alarming rate to maintain the distortion field, essential to deflect the hail of stone from the hull. And they would need that power later, no matter what the outcome at Tanjuntic-RI. She told Oenone to halt and match the orbital vector of the surrounding particles.
Once Etchells realized he was no longer being actively pursued, he also eased back, and simply held his position. They were no more than fifteen kilometres apart. Though the only way they knew that was by sensing each other with their distortion fields, visual or radar observation was impossible.

He obviously wasn’t aware they’d landed the team in Tanjuntic-RI. All they had to do was keep him here until Oski and Renato had accessed the files.

The links between the second and third levels on Tanjuntic-RI were mainly cargo lifts. Again, each of them was wrapped by the ubiquitous spiralling ramps. The exploration team had to engage their boot spikes as they made their way down one which led to ring five. Icy floors combined with the strengthening gravity provided a treacherous environment.
There was a large airlock chamber at the bottom, with doors more suited to bank vaults than spaceships. But this had been the Tyrathca’s first line of defence against a breach in the upper levels, their design philosophy had come into its own here. As tribute to that efficiency, Tanjuntic-RI’s caverns and rings still retained a tiny atmosphere after thirteen centuries of disuse.
A cache of human machinery was spread out before the door at the end of the ramp: a couple of microfusion generators, mobile cherry-picker platforms, industrial thermal inducer plates, hydraulic rams, and electromechanical actuators; all hooked together with loosely bundled cables and flexible hoses. The archaeology expedition had used them to reactivate the massive airlock. It was a quarter open, allowing them access to ring five. Four small jeeps were parked just inside, standard airless-planet mobility vehicles, with large low-pressure tyres and a composite latticework chassis. Ridiculously dainty in comparison to the engineering on display around them.
Samuel went over and inspected them, flicking switches on the dashboard.
“I’m getting a response from the control processor,” he datavised.
“There’s some power left in the standby circuits, but that’s about all. The main energy cells are dead.”
“Irrelevant,” Monica datavised. She ordered her suit lamps to emit a high-wattage pulse, and readied the sensors. Her neural nanonics memory froze the image when the lights flared. Buffer programs isolated the image for her to examine.
Not even the suit’s lights could penetrate the gloom right across the ring. As a result, the curvature effect was completely lost. She was standing in a metal cave, walls, floor, and ceiling made up from millions of aluminium alloy panels, heat sealed to the naked rock underneath and welded together. Plants had been grown up the walls while the arkship was occupied, vigorous creepers clawing their way along metal trellises.
Their leaves were black and wizened now, dead from lack of water and light long before the heat seeped away into space. But the cold had arrived before they’d fallen in their final autumn, sprinkling them with frost then freezing them into place against the dull metal tiling.
The ring’s ceiling had an analogue in human warehouse roofs; criss crossed with thick pipes and sturdy gantry crane rails, giving the vast chamber an overtly industrial feel. Its illumination had been provided by thousands of large circular disks of smoked glass, which peered out of the gaps.
“A winter wonderland palace,” Monica datavised. “Even if it was built by the devil’s own elves.”
“How could they live in this, for Christ’s sake?” Renato asked. “It’s just a machine. There’s no attempt to make it pleasing or hospitable. You couldn’t stay inside all of your life, it would drive you insane.”
“Us,” Oski datavised. “Not them. They don’t have our psychological profile.”
“I expect they would find one of our habitats to be equally disenchanting,” Samuel said.
“The Tyrathca have arrived,” one of the serjeants datavised.
Everyone saw it through the sensor disk Monica had left up in level one.
A flash of light from the airlock which led up to the spaceport support column. Large jagged sections of the square titanium hatch flew into the corridor, rebounding from the walls amid cascades of ice chips to twirl away in both directions. The Tyrathca emerged, and began moving in a slow canter towards the entrance to the spiral ramp. They were in spacesuits, which made it hard to tell between breeders and soldiers. Although the SII had tried many times to sell them programmable silicon suits modified to their physiology, they’d resolutely stuck to their own original design.
The body of Tyrathca spacesuits was made from a tough flexible plastic, a silvery blue in colour, like metallic silk. They formed overalls that were loose and baggy enough for the big creatures to slip into easily, with concertina-like tubes for legs and arms. After that, instead of inflating them with oxygen, they were pumped full with a thick gel, expelling all the air. Given how many limbs (and therefore joints) a Tyrathca body had, such a concept neatly did away with the problem of providing multiple pressurized joints on every suit. In order to breathe, they wore simple tight-fitting masks inside the suits. Oxygen tanks, a regulator mechanism, and a heat exchanger were worn in a pack along their backs, with two black radiator fins running along their spine. Additional equipment was carried on a harness around their necks.
“Looks like subtlety is another trait we don’t share,” Monica datavised.
“They must have blown out every airlock along that first corridor to get inside. The sensor disk is registering a lot of gas motion in that corridor. They just don’t care that Tanjuntic-RI is going to vent its remaining atmosphere.”
“If they don’t, we shouldn’t,” Renato datavised. “It won’t affect our mission.”
“They’re all armed,” Samuel datavised. “Even the breeders.”
The Tyrathca were each carrying a pair of long matte-black rifles, with coiled leads plugged into power packs on their harnesses. Mo
nica put an armaments library file into primary mode, and let it run through the catalogue for a match. “Masers,” she datavised. “Fairly basic medium-output projectors. Our armour should withstand an energy strike from them. But if we get caught in a saturation situation we’ll be in trouble. And they’re carrying other ordnance as well. I think I can make out some guided rockets, and EE grenades on those harnesses. Human-built.”
“I wonder who sold those to them,” Oski datavised. “I thought the Confederation didn’t permit armaments sales to the Tyrathca.”
“Not relevant,” Samuel datavised. “Come on, let’s locate that control office the archaeology expedition found.”
Monica bled in her suit sensor’s infrared visualization as they moved off. The Tyrathca buildings materialized around her, tapering towers of a pale blue luminescence, like flame frozen against the empty blackness which stretched out along the ring. It was a cold necropolis, with every street and building identical, as if each section had been stamped from the same die and laid out end to end. Gardens of tangled plants besieged each of the towers, their entwined stalks caught in the act of sagging.
Unrelenting cold had turned the vegetation as hard and black as cast iron. Fanciful leaves, strangely shaped flowers and bloated seed pods had all been reduced to the same sombre shade of charcoal.
“Damn, those Tyrathca can move fast in low-gee,” Samuel datavised. They hadn’t been walking ten minutes, and already the Tyrathca had reached the bottom of the first spiral ramp. A sensor disk showed one of them sweeping a portable electronic scanner over the floor while the others waited behind. The group split into three, following the various thermal trails.
“I make that eighteen coming our way,” Monica datavised. “I think we’ve got four breeders. They’re slightly larger.”
“I will return to the entrance,” one of the serjeants datavised. “I will have time to lay several false heat trails before they reach this ring. That should split them again. And I may manage to close the airlock door. Either way, it will reduce the force that will ultimately pursue you.”
