Symbionts

by William H. Keith

  No, that wasn’t quite correct. He couldn’t forget about cloudscreens, not having used them in his spaceborne assault that had taken Eagle from her Japanese masters, and again in his raid at the Imperial shipyard at Athena. They were a basic part of modern space combat tactics, as elementary as radar, and he’d given orders to use them liberally during the approach, to screen the fighters.

  What had failed, he feared, was his identification with the men and women occupying the ships and fighters swarming now around the embattled mountain that was Karyu. He’d been thinking of Katya’s striders, directed through the Naga link of his symbiosis, as a part of him, something that didn’t need protection.

  Technomegalomania… a feeling that he was invulnerable within the aura of high-tech magic that linked him with organic minds and electronic systems distributed across a thousand kilometers of space. What he’d forgotten was that those motes drifting toward the Karyu were humans. People. Friends.

  Damn! He could have killed her!…

  Elsewhere, the enemy escorts were moving in closer now, and the tide of battle appeared to be swinging around, turning against the Confederation assault force. Rebel was dead. So was the corvette Daring, savaged by repeated hits by lasers, particle beams, and rounds from the carrier’s hivel cannons. Constellation was adrift, her engines shut down, her maneuvering system shot to bits, though she continued to blaze away at Karyu and the other Imperial ships with as many batteries as she could bring to bear. Eagle was practically touching the Ryu-carrier, still fighting and moving but with half of her turrets out of action and a portion of her starboard flank glowing red-hot.

  In bloody exchange, one Imperial frigate had been destroyed by a missile salvo launched by Eagle, and a light destroyer had been badly damaged. A light cruiser had tried to come up astern of the Eagle, but a sudden, unexpected barrage from Constellation loosed past the looming, black-and-gray barricade of Karyu’s flank had punctured the larger ship’s armor in a dozen places and left her powerless, at least for the moment.

  And Dev watched over the carnage like a bloody-handed colossus, like a god of war, hurling his people into that sacrificial altar. Enemy fighters were swarming around the beleaguered Karyu now, hunting down the warstriders clinging to her back.

  God… Katya!…

  Had his own people become such… such faceless tools that he no longer thought of them as flesh and blood?…

  A Soritaka fighter angled down out of a silver sky rapidly tattering away to star-filled black. Soundlessly, gouts of white fire erupted from the hull-metal ground twenty meters away. “Kurt!” Katya screamed over the strider’s ICS. “Nail him!”

  “Tracking!”

  The Warlord’s dorsal hivel cannon pivoted, and Katya sensed the vibration of its buzz saw fire…

  … and then the fighter was past them, its wings aglow in sunlight. A missile detonated, and shrapnel slapped off the hull of Katya’s warstrider. A second fighter flashed in the sunlight… a third… a fourth.

  “Damn it, they’re too fast!” Kurt yelled. “And there’s too many of them. Here comes another!…”

  God, Karyu’s whole damned fighter wing must be out here, picking off the warstriders like vermin. Another silent explosion, and Hari Sebree was screaming wildly in her mind’s ear, a rasping wail of sheer agony… and then his stricken Scoutstrider ruptured in a glowing sphere of hot gas and fragments.

  The gap in Karyu’s hull yawned a hundred meters ahead, a tunnel, a cavern yawning into the carrier’s vitals. Katya exerted her will through the Naga and streaked across broken and flame-streaked metal toward its shelter.

  Shaken by the slaughter, shaken worse by his new insight into the bloody workings of his own mind, Dev extended his will, reaching out to the other DalRiss ships. He’d hoped to keep the other DalRiss vessels out of it. Maybe, he thought, he was still thinking like a human after all: I can’t ask that of them.

  And neither could he watch the slaughter of his people and do nothing.

  In lightning pulses of thought, he relayed his last orders to the far-flung network of DalRiss ships. The DalRiss ships themselves were unarmed, but extrusions of the Naga fragment nested within each provided a weapon as devastating as any in the Confederation or Imperial arsenals. Drawing on the Dal-ships for power, the Nagas generated intense, tightly focused magnetic fields, using them to accelerate kilogram-sized chunks of themselves to speeds of hundreds of kilometers per second.

  An Imperial light cruiser overhauling Karyu from astern took a chain of five hard-flung projectiles in rapid-fire succession, the impacts flaring white-hot in searing explosions of vaporized armor and escaping gases. The bow section of the cruiser shattered, the rest of the vessel’s length crumpling and folding and splitting wide open beneath that storm of high-velocity death. A corvette took three rounds and vanished in a dazzling nova-flash of light.

  Daghar, meanwhile, was moving again, gathering its energies for yet another short-range leap. Dev, his thoughts flickering from vessel to vessel, momentarily sought the bright node of familiar warmth that was Katya. Was she even still alive after descending through that wall of fire?

  Yes! He sensed her through her Naga’s touch. Briefly, he glimpsed her surroundings through her Warlord’s sensors… a storm of laser and particle beam fire as she led twenty or thirty of her warstriders toward a gaping, flame-shot maw opening in the side of the Imperial carrier.

  But enemy fighters wheeled toward her. She wasn’t going to make it.…

  “Niner-niner,” Dev said. “This is Changeling. Get ready, everybody! I’m going to provide a diversion with the Daghar! You’re all on your own! When you see your chance, take it and go!”

  Goodbye, Katya.…

  “Good luck, all of you.…”

  Jump!…

  * * *

  So far, the entire battle had been taking place in Herakles’s orbit, with all of the vessels involved moving at more or less the same velocity and, except for the back-and-forth slashes of the highly maneuverable fighters, in more or less the same direction.

  Now, though, the small suns tucked away within the cavernous overhangs of Karyu’s stern flashed on. Cones of charged particles, as hot as the wind sweeping from the face of the sun, blasted astern, driving the monster carrier’s ponderous bulk slowly forward, and when by chance they swept across Daring’s riddled and dying hulk, they turned armor incandescent and killed instantly every man and woman still alive aboard the crippled corvette.

  Faster and faster.Under one gravity of acceleration, the carrier broke orbit, angling out and away from the storm-wracked planet. Those ships that could still move and maneuver followed, Imperial and Confederation both. The hulks—Rebel and Daring and the dead Imperial escorts—the cripples—Constellation and the powerless light cruiser—remained in Heraklean orbit, falling farther and farther behind.

  “They’re moving!” Katya cried over the tacnet. “The bastards are moving out!” The side of the crater lunged toward her, slammed against her Warlord’s hull… and then suddenly there was gravity again as acceleration dragged at the strider’s frame. Katya’s orientation swung wildly for a moment, bringing with it a stab of vertigo. Down was that way, toward Karyu’s stern, and she was balanced on the lip of a giant crater, together with a handful of other warstriders as the carrier drove “upward” into space.

  For a moment, she wondered if the Imperials were running, but immediately she discarded the idea. No, damn it, the Impies were winning… winning! By breaking orbit, they could lose the Constellation, which was continuing to snipe at the Imperial ships even though her main drive was down, and they might well shake some of the other ships that were snapping at her fire-torn flanks like hunting dogs. So far, the only thing keeping the Confederation ships alive was the fact the Karyu herself offered pretty good cover.

  The enemy fighters had momentarily vanished from the sky, but they would be back, matching accelerations with the Karyu and continuing to blast the warstriders from their toeholds on
her hull.

  Then Daghar was back, two kilometers away and so huge it filled that half of the sky, making Katya feel as though she was clinging to the side of a cliff in a steep-sided valley, with canyon walls extending above and below her for as far as she could see.

  She’d heard Dev’s transmission, but she’d been too busy at the moment for its meaning to seep through to awareness. Kuso, what was the damned fool doing now?…

  At a range of two kilometers, Dev was throwing rocks again… kilogram-sized chunks of the Naga itself, accelerated to high speed and hurled across the narrow gap into Karyu’s stern section, just forward of the ravening blast of her flaring plasma drives.

  In a ship as large and as massive as the Karyu, the vast majority of the ship’s hull is armor, or fuel tankage, or skyscraper-sized masses of circuits and power feeds, fusorpacks and sensor leads, all of them multiply redundant and with remarkably few vulnerable points. Ryu-class carriers were designed to survive, which meant there were no isolated places that could be precisely targeted for a kill… or simply taken out by a stray, lucky shot.

  At point-blank range, though, Dev could target the general area directly ahead of Karyu’s huge drive Venturis. Somewhere beneath meter upon meter of duralloy and fabricrete plating would be the fusion chambers that fed those flaming suns astern… and the pumps that fed them with cryo-H, the lasers that flashed the hydrogen to fusion heat, the fusorpack-driven generators that powered the magnetic bottles and containment fields.

  A stream of pellets slammed into Karyu’s dorsal hull with an impact felt throughout the ship like the blasting of a jack-hammer against a tin roof. Cubic meters of duralloy and steel vaporized; a crater yawned; inner circuitry and power feeds and tubing flashed and vanished like cotton in the blast of a blowtorch.

  For a fraction of a second, the fusion reaction in Karyu’s drive chamber threatened to run wild. As magnetic grids failed, though, the ship’s AI recognized the danger of imminent containment field failure and scrammed the entire network. The ship’s driving suns winked out.…

  “Fire control!” Admiral Miyagi screamed over the combat net. “Concentrate on that damned alien!” The ship’s drive had just cut out, and they were in free-fall once more. In another moment, that gaijin starfish would peel the mighty Karyu open from stem to bow. “Kill it! Kill it!”

  Karyu’s remaining weapons swung about, tracking the Alyan monster. The fighters shifted aim too, loosing the first of a swarm of missiles against the huge DalRiss ship’s hull.

  Zero-G again. Katya drifted above the gaping crater in Karyu’s side. The other warstriders that had been trapped with her and been freed when the carrier stopped accelerating were flashing past her and into the cavern. Others, those that had been caught by surprise when the Ryu began accelerating, were catching up now, flashing in from astern on hard-driven Naga mag fields. It was almost eerily peaceful in her small part of the battlefield. The fighters were gone, the PDL fire was concentrating on another target.

  Katya was unable to move, however, unable to will the Warlord into the yawning darkness of that cave. Her full attention was focused on the Daghar, drifting now a little way astern of the Karyu. Imperial fire was tearing into the Alyan city-ship; its organic hide was not nearly so tough or so resilient as duralloy, or the other artificial, nano-layered materials of human technology. Missiles slammed home, each one burying deep beneath the ship-creature’s hide before detonating, each detonation flinging huge, fiercely radiating chunks of tissue into space.

  It looked as though the entire, star-shaped mass was burning with a radiant, white-glaring flame.

  “God!” she screamed. “God! No! Dev!”

  The DalRiss ship’s explosion lit the blackness of space like the utterly silent, eye-searing flash of a supernova.

  413 B.C.E.

  Once the Confederation warstriders smashed their way on board the Imperial Ryu-carrier, the outcome of the battle was a foregone conclusion. There were Imperial Marines aboard the Karyu, and several thousand surviving crewmen, despite heavy losses during the battle, but Imperial naval vessels did not routinely carry the sort of weapons, as shipboard sidearms, that would make any impression at all against a warstrider.

  Katya learned later that teams of warstriders, too large and bulky and clumsy to move or stand upright within the thousands of kilometers of passageways filling that city-sized ship, had dragged themselves along with weapon-heavy arms gouging and clawing into centimeter-thick bulkheads, or propelled themselves with the magnetic push of their Nagas, burrowing headfirst like enormous, duralloy-sheathed moles, tearing up decks, smashing down partitions, plowing through every barrier in their path. Each time they burned or smashed their way through interior bulkheads into a new section, they were met by storms of escaping atmosphere that shrieked out through the opening in whirling snowstorms of freezing water vapor and air. As assault teams moved ahead, the ship’s damage control systems sealed off breaches behind them and repressurized those areas of the ship that had been depressurized, but those systems could only take so much punishment before they started to fail. More and more Confederation strider teams blasted their way aboard, some through air locks, some through shattered gun turrets and external hardpoints, and most, like those with Katya, through the breaches blasted open by naval gunfire and warflyer assault and missiles, and soon whole sections of the ship were closing down as cold, hard vacuum claimed their passageways and compartments, and severed power feeds plunged them into darkness.

  In all, 265 Rangers made it aboard the Karyu and began fighting their way forward, one passageway at a time. Imperial Marines, many in heavy armor, fought back, but the only casualty was the pilot of a Scoutstrider that had already suffered heavy damage from laser fire during the approach. The hand laser fire from a team of Imperial Marines blew an already weakened access panel; when the circuit boards beyond vaporized, a bolt of high-amp current downloaded through the unfortunate pilot’s brain, killing him instantly.

  Marines or crew personnel who tried to make stands at critical corridor junctions were fried by blasts from lasers or particle guns, or cut down by blasts from hivel cannons or machine guns. Few of the defenders cared to stand in place and fight back when the corridor-filling bulk of a Ghostrider or Swiftstrider dragged itself into view. As a result, many of the ship’s larger compartments—recreation decks and barracks, supply vaults and hangar bays—grew more and more crowded with ship’s personnel who’d given up the fight and were simply looking for a place, anyplace, to escape the crawling, armored behemoths. Those who could reach Karyu’s escape pods and lifeboats abandoned ship, filling circumambient space with the drifting sparkle of strobing emergency beacons.

  Miyagi broadcast a general call to all personnel to fight to the death. Few in his crew had radios or compatches, however, and most intercom channels were off-line by that time, so the only ones to get the order were the marines. These retreated when they could and fought to the death when they had to. Soon it was clear that even the most valiant efforts—headlong, zero-G charges down fire-filled corridors dragging satchels of explosives—could avail nothing against warstriders, which could spot such teams as soon as they came into view and sweep them with laser or projectile fire.

  Twenty-eight minutes after the first warstriders smashed their way through blast-charred bulkheads and into the still-pressurized portion of the ship, the first warstriders reached the bridge, buried at the ship’s core some two hundred meters from the first entry point. At that point, a pale and shaking Admiral Miyagi emerged from the link module from which he’d been directing the battle, then brought the muzzle of his own laser pistol to his head and pulled the trigger.

  His second-in-command broadcast the call for surrender.

  Katya saw little of this at the time. Dev was dead… dead. The agony of that realization filled her min
d, blocking her thoughts, blinding her to the battle that was continuing to flash and stab across the heavens. She knew that she ought to join the fight. Damn it all… this amounted to dereliction of duty, hanging here in space watching men die.

  She opened her link to the Naga, urging it to move.

  She failed.

  Oh, kuso. She ran a diagnostic, found nothing wrong, and tried again. Still nothing. “Kurt? Ryan?”

  “We’re here, Colonel.”

  “I… I’m having some trouble.”

  Kurt’s voice sounded a bit distant. “I think there’s a fault. Maybe in the interface with the Naga. I’m working on it.”

  “We’ll hold position here okay,” Ryan told her. “Don’t think they’ll be needing us, though. Everything looks pretty much in hand.”

  “I’m… I’m sorry about the commodore, Colonel,” Kurt Allen said. “I know you two were pretty close.”

  “Yeah. We were… close.”

  “Can we do anything?”

  “Sign off. Let me… deal with it. Okay?”

  “Sure, Colonel,” Ryan said. “We’ll be on sentry, and jacked in if you need us.”

  “And let me know as soon as you have the problem fixed. We should… should be moving.”

  The rest of the battle was clearly almost over. Though the human ships had been badly handled, the surviving DalRiss vessels, most still fresh and relatively untouched by the storm thus far, were continuing to hurl their high-velocity projectiles, slamming them one after another into the Imperial ships. Even before Karyu gave up, several of the smaller Imperial ships were drawing off at high speed. When Karyu’s XO broadcast his surrender, the rest of the Imperial battlefleet was already more than willing to break off the fight and begin accelerating for open space. One after another, they arrowed out into the night beyond Herakles’s orbit, then vanished into K-T space.
