Beyond the Aquila Rift: The Best of Alastair Reynolds

by Alastair Reynolds

  “It could work.”

  “Yes…” Galiana seemed lost momentarily. “I suppose it could be a way out of the impasse. Our own attempt failed too—and the interdiction’s stopped us from trying again.” Again, she seemed to fall into reverie. “But who would really benefit from the flushing out of Phobos? We’d still be quarantined here.”

  Clavain leaned forward. “A co-operative gesture might be exactly the thing to lead to a relaxation in the terms of the interdiction. But don’t think of it in those terms. Think instead of reducing the current threat from the worms.”

  “Threat?”

  Clavain nodded. “It’s possible that you haven’t noticed.” He leaned forward, elbows on the table. “We’re concerned about the Phobos worms. They’ve begun altering the moon’s orbit. The shift is tiny at the moment, but too large to be anything other than deliberate.”

  Galiana looked away from him for an instant, as if weighing her options. Then said: “We were aware of this, but you weren’t to know that.”

  Gratitude?

  He had assumed the worms’ activity could not have escaped Galiana. “We’ve seen odd behaviour from other worm infestations across the system; things that begin to look like emergent intelligence. But never anything this purposeful. This infestation must have come from a batch with some subroutines we never even guessed about. Do you have any ideas about what they might be up to?”

  Again, there was the briefest of hesitations, as if she was communing with her compatriots for the right response. Then she nodded toward a male Conjoiner sitting opposite her, Clavain guessing that the gesture was entirely for his benefit. His hair was black and curly; his face as smooth and untroubled by expression as Galiana’s, with something of the same beautifully symmetrical bone structure.

  “This is Remontoire,” said Galiana. “He’s our specialist on the Phobos situation.”

  Remontoire nodded politely. “In answer to your question, we currently have no viable theories as to what they’re doing, but we do know one thing. They’re raising the apocentre of the moon’s orbit.” Apocentre, Clavain knew, was the Martian equivalent of apogee for an object orbiting Earth: the point of highest altitude in an elliptical orbit. Remontoire continued, his voice as preternaturally calm as a parent reading slowly to a child. “The natural orbit of Phobos is actually inside the Roche limit for a gravitationally-bound moon; Phobos is raising a tidal bulge on Mars but, because of friction, the bulge can’t quite keep up with Phobos. It’s causing Phobos to spiral slowly closer to Mars, by about two metres a century. In a few tens of millions of years, what’s left of the moon will crash into Mars.”

  “You think the worms are elevating the orbit to avoid a cataclysm so far in the future?”

  “I don’t know,” Remontoire said. “I suppose the orbital alterations could also be a by-product of some less meaningful worm activity.”

  “I agree,” Clavain said. “But the danger remains. If the worms can elevate the moon’s apocentre—even accidentally—we can assume they also have the means to lower its pericentre. They could drop Phobos on top of your nest. Does that scare you sufficiently that you’d consider co-operation with the Coalition?”

  Galiana steepled her fingers before her face; a human gesture of deep concentration which her time as a Conjoiner had not quite eroded. Clavain could almost feel the web of thought looming the room; ghostly strands of cognition reaching between each Conjoiner at the table, and beyond into the nest proper.

  “A winning team, is that your idea?”

  “It’s got to be better than war,” Clavain said. “Hasn’t it?”

  Galiana might have been about to answer him when her face grew troubled. Clavain saw the wave of discomposure sweep over the others almost simultaneously. Something told him that it was nothing to do with his proposal.

  Around the table, half the display facets switched automatically over to another channel. The face that Clavain was looking at was much like his own, except that the face on the screen was missing an eye. It was his brother. Warren was overlaid with the official insignia of the Coalition and a dozen system-wide media cartels.

  He was in the middle of a speech. “…express my shock,” Warren said. “Or, for that matter, my outrage. It’s not just that they’ve murdered a valued colleague and deeply experienced member of my team. They’ve murdered my brother.”

  Clavain felt the deepest of chills. “What is this?”

  “A live transmission from Deimos,” Galiana breathed. “It’s going out to all the nets; right out to the trans-Pluto habitats.”

  “What they did was an act of unspeakable treachery,” Warren said. “Nothing less than the pre-meditated, cold-blooded murder of a peace envoy.” And then a video clip sprang up to replace Warren. The image must have been snapped from Deimos or one of the interdiction satellites. It showed Clavain’s shuttle, lying in the dust close to the dyke. He watched the Ouroborus destroy the shuttle, then saw the image zoom in on himself and Voi, running for sanctuary. The Ouroborus took Voi. But this time there was no ladder lowered down for him. Instead, he saw weapon-beams scythe out from the nest toward him, knocking him to the ground. Horribly wounded, he tried to get up, to crawl a few inches nearer to his tormentors, but the worm was already upon him.

  He watched himself get eaten.

  Warren was back again. “The worms around the nest were a Conjoiner trap. My brother’s death must have been planned days—maybe even weeks—in advance.” His face glistened with a wave of military composure. “There can only be one outcome from such an action—something the Conjoiners must have well understood. For months they’ve been goading us toward hostile action.” He paused, then nodded at an unseen audience. “Well now they’re going to get it. In fact, our response has already commenced.”

  “Dear God, no,” Clavain said, but the evidence was all there now; all around the table he could see the updating orbital spread of the Coalition’s dropships, knifing down toward Mars.

  “I think it’s war,” Galiana said.

  CONJOINERS STORMED ONTO the roof of the nest, taking up defensive positions around the domes and the dyke’s edge. Most of them carried the same guns which they had used against the Ouroborus. Smaller numbers were setting up automatic cannon on tripods. One or two were manhandling large anti-assault weapons into position. Most of it was war-surplus. Fifteen years ago the Conjoiners had avoided extinction by deploying weapons of awesome ferocity—but those ship-to-ship armaments were too simply too destructive to use against a nearby foe. Now it would be more visceral; closer to the primal templates of combat, and none of what the Conjoiners were marshalling would be much use against the kind of assault Warren had prepared, Clavain knew. They could slow an attack, but not much more than that.

  Galiana had given him another breather mask, made him don lightweight chameleoflage armour, and then forced him to carry one of the smaller guns. The gun felt alien in his hands; something he had never expected to carry again. The only possible justification for carrying it was to use it against his brother’s forces—against his own side.

  Could he do that?

  It was clear that Warren had betrayed him; he had surely been aware of the worms around the nest. So his brother was capable not just of contempt, but of treacherous murder. For the first time, Clavain felt genuine hatred for Warren. He must have hoped that the worms would destroy the shuttle completely and kill Clavain and Voi in the process. It must have pained him to see Clavain make it to the dyke…pained him even more when Clavain called to talk about the tragedy. But Warren’s larger plan had not been affected. The diplomatic link between the nest and Deimos was secure—even the Demarchists had no immediate access to it. So Clavain’s call from the surface could be quietly ignored; spysat imagery doctored to make it seem that he had never reached the dyke…had in fact been repelled by Conjoiner treachery. Inevitably the Demarchists would unravel the deception given time…but if Warren’s plan succeeded, they would all be embroiled in war long befor
e then. That, thought Clavain, was all that Warren had ever wanted.

  Two brothers, Clavain thought. In many ways so alike. Both had embraced war once, but like a fickle lover Clavain had wearied of its glories. He had not even been injured as severely as Warren…but perhaps that was the point, too. Warren needed another war to avenge what one had stolen from him.

  Clavain despised and pitied him in equal measure.

  He searched for the safety clip on the gun. The rifle, now that he studied it more closely, was not all that different from those he had used during the war. The readout said the ammo-cell was fully charged.

  He looked into the sky.

  The attack wave broke orbit hard and steep above the Wall; five hundred fireballs screeching toward the nest. The insertion scorched inches of ablative armour from most of the ships; fried a few others which came in just fractionally too hard. Clavain knew that was how it was happening: he had studied possible attack scenarios for years, the range of outcomes burned indelibly into his memory.

  The anti-assault guns were already working—locking onto the plasma trails as they flowered overhead, swinging down to find the tiny spark of heat at the head, computing refraction paths for laser pulses, spitting death into the sky. The unlucky ships flared a white that hurt the back of the eye and rained down in a billion dulling sparks. A dozen—then a dozen more. Maybe fifty in total before the guns could no longer acquire targets. It was nowhere near enough. Clavain’s memory of the simulations told him that at least four hundred units of the attack wave would survive both re-entry and the Conjoiner’s heavy defences.

  Nothing that Galiana could do would make any difference.

  And that had always been the paradox. Galiana was capable of running the same simulations. She must always have known that her provocations would bring down something she could never hope to defeat.

  Something that was always going to destroy her.

  The surviving members of the wave were levelling out now, commencing long, ground-hugging runs from all directions. Cocooned in their dropships, the soldiers would be suffering punishing gee-loads… but it was nothing they were not engineered to withstand; half their cardiovascular systems were augmented by the only kinds of implant the Coalition tolerated.

  The first of the wave came arcing in at supersonic speeds. All around, worms struggled to snatch them out of the sky, but mostly they were too slow to catch the dropships. Galiana’s people manned their cannon positions and did their best to fend off what they could. Clavain clutched his gun, not firing yet. Best to save his ammo-cell power for a target he stood a chance of injuring.

  Above, the first dropships made hairpin turns, nosing suicidally down toward the nest. Then they fractured cleanly apart, revealing falling pilots clad in bulbous armour. Just before the moment of impact each pilot exploded into a mass of black shock-absorbing balloons, looking something like a blackberry, bouncing across the nest before the balloons deflated just as swiftly and the pilot was left standing on the ground. By then the pilot—now properly a soldier—would have a comprehensive computer-generated map of the nest’s nooks and crannies; enemy positions graphed in realtime from the down-looking spysats.

  Clavain fell behind the curve of a dome before the nearest soldier got a lock onto him. The firefight was beginning now. He had to hand it to Galiana’s people—they were fighting like devils. And they were at least as well co-ordinated as the attackers. But their weapons and armour were simply inadequate. Chameleoflage was only truly effective against a solitary enemy, or a massed enemy moving in from a common direction. With Coalition forces surrounding him, Clavain’s suit was going crazy trying to match itself against every background, like a chameleon in a house of mirrors.

  The sky overhead looked strange now—darkening purple. And the purple was spreading in a mist across the nest. Galiana had deployed some kind of chemical smoke screen: infrared and optically opaque, he guessed. It would occlude the spysats and might be primed to adhere only to enemy chameleoflage. That had never been in Warren’s simulations. Galiana had just given herself the slightest of edges.

  A soldier stepped out of the mist, the obscene darkness of a gun muzzle trained on Clavain. His chameleoflage armour was dappled with vivid purple patches, ruining its stealthiness. The man fired, but his discharge wasted itself against Clavain’s armour. Clavain returned the compliment, dropping his compatriot. What he had done, he thought, was not technically treason. Not yet. All he had done was act in self-preservation.

  The man was wounded, but not yet dead. Clavain stepped through the purple haze and knelt down beside the soldier. He tried not to look at the man’s wound.

  “Can you hear me?” he said. There was no answer from the man, but beneath his visor, Clavain thought he saw the man’s lips shape a sound. The man was just a kid—hardly old enough to remember much of the last war. “There’s something you have to know,” Clavain continued. “Do you realise who I am?” He wondered how recognisable he was, under the breather mask. Then something made him relent. He could tell the man he was Nevil Clavain—but what would that achieve? The soldier would be dead in minutes; maybe sooner than that. Nothing would be served by the soldier knowing that the basis for his attack was a lie; that he would not in fact be laying down his life for a just cause. The universe could be spared a single callous act.

  “Forget it,” Clavain said, turning away from his victim.

  And then moved deeper into the nest, to see who else he could kill before the odds took him.

  BUT THE ODDS never did.

  “You were always were lucky,” Galiana said, leaning over him. They were somewhere underground again—deep in the nest. A medical area, by the look of things. He was on a bed, fully clothed apart from the outer layer of chameleoflage armour. The room was grey and kettle-shaped, ringed by a circular balcony.

  “What happened?”

  “You took a head wound, but you’ll survive.”

  He groped for the right question. “What about Warren’s attack?”

  “We endured three waves. We took casualties, of course.”

  Around the circumference of the balcony were thirty or so grey couches, slightly recessed into archways studded with grey medical equipment. They were all occupied. There were more Conjoiners in this room than he had seen so far in one place. Some of them looked very close to death.

  Clavain reached up and examined his head, gingerly. There was some dried blood on the scalp, matted with his hair; some numbness, but it could have been a lot worse. He felt normal—no memory drop-outs or aphasia. When he made to stand from the bed, his body obeyed his will with only a tinge of dizziness.

  “Warren won’t stop at just three waves, Galiana.”

  “I know.” She paused. “We know there’ll be more.”

  He walked to the railing on the inner side of the balcony and looked over the edge. He had expected to see something—some chunk of incomprehensible surgical equipment, perhaps—but the middle of the room was only an empty, smooth-walled, grey pit. He shivered. The air was colder than any part of the nest he had visited so far, with a medicinal tang which reminded him of the convalescence ward on Deimos. What made him shiver even more was the realisation that some of the injured—some of the dead—were barely older than the children he had visited only hours ago. Perhaps some of them were those children, conscripted from the nursery since his visit, uploaded with fighting reflexes through their new implants.

  “What are you going to do? You know you can’t win. Warren lost only a tiny fraction of his available force in those waves. You look like you’ve lost half your nest.”

  “It’s much worse than that,” Galiana said.

  “What do you mean?”

  “You’re not quite ready yet. But I can show you in a moment.”

  He felt colder than ever now. “What do you mean, not quite ready?”

  Galiana looked deep into his eyes now. “You took a serious head wound, Clavain. The entry wound was small, but the inter
nal bleeding… it would have killed you, had we not intervened.” Before he could ask the inevitable question she answered it for him. “We injected a small cluster of medichines into your head. They undid the damage very easily. But it seemed provident to allow them to grow.”

  “You’ve put replicators in my head?”

  “You needn’t sound so horrified. They’re already growing—spreading out and interfacing with your existing neural circuitry—but the total volume of glial mass that they will consume is tiny: only a few cubic millimetres in total, across your entire brain.”

  He wondered if she was calling his bluff. “I don’t feel anything.”

  “You won’t—not for a minute or so.” Now she pointed into the empty pit in the middle of the room. “Stand here and look into the air.”

  “There’s nothing there.”

  But as soon as he had spoken, he knew he was wrong. There was something in the pit. He blinked and directed his attention somewhere else, but when he returned his gaze to the pit, the thing he imagined he had seen—milky, spectral—was still there, and becoming sharper and brighter by the second. It was a three-dimensional structure, as complex as an exercise in protein-folding. A tangle of loops and connecting branches and nodes and tunnels, embedded in a ghostly red matrix.

  Suddenly he saw it for what it was: a map of the nest, dug into Mars. Just as the Coalition had suspected, the base was deeper than the original structure; far more extensive, reaching deeper down but much further out than anyone had imagined. Clavain made a mental effort to retain some of what he was seeing in his mind, the intelligence-gathering reflex stronger than the conscious knowledge that he would never see Deimos again.

  “The medichines in your brain have interfaced with your visual cortex,” Galiana said. “That’s the first step on the road to Transenlightenment. Now you’re privy to the machine-generated imagery encoded by the fields through which we move—most of it, anyway.”

  “Tell me this wasn’t planned, Galiana. Tell me you weren’t intending to put machines in me at the first opportunity.”
