Conservation of Shadows

by Yoon Ha Lee

  In her dreams, later, the blast pattern took on the outline of a running wolf.

  In the mercenaries’ dominant language, jerengjen originally referred to the art of folding paper. For her part, when Lisse first saw it, she thought of it as snow. She was four years old. It was a fair spring afternoon in the City of Tapestries, slightly humid. She was watching a bird try to catch a bright butterfly when improbable paper shapes began drifting from the sky, foxes and snakes and stormbirds.

  Lisse called to her parents, laughing. Her parents knew better. Over her shrieks, they dragged her into the basement and switched off the lights. She tried to bite one of her fathers when he clamped his hand over her mouth. Jerengjen tracked primarily by shadows, not by sound, but you couldn’t be too careful where the mercenaries’ weapons were concerned.

  In the streets, jerengjen unfolded prettily, expanding into artillery with dragon-shaped shadows and sleek four-legged assault robots with wolf-shaped shadows. In the skies, jerengjen unfolded into bombers with kestrel-shaped shadows.

  This was not the only Rhaioni city where this happened. People crumpled like paper cutouts once their shadows were cut away by the onslaught. Approximately one-third of the world’s population perished in the weeks that followed.

  Of the casualty figures, the Imperium said, It is regrettable. And later, The stalled negotiations made the consolidation necessary.

  Lisse carried a map of the voidways with her at all times, half in her head and half in the Scorch deck. The ghost had once been a traveler. It had shown her mnemonics for the dark passages and the deep perils that lay between stars. Growing up, she had laid out endless tableaux between her lessons, memorizing travel times and vortices and twists.

  Ashway 514 lay in the interstices between two unstable stars and their cacophonous necklace of planets, comets, and asteroids. Lisse felt the kite tilting this way and that as it balanced itself against the stormy voidcurrent. The tapestries shone from one side with ruddy light from the nearer star, 514 Tsi. On the other side, a pale violet-blue planet with a serenade of rings occluded the view.

  514 was a useful hiding place. It was off the major tradeways, and since the Battle of Fallen Sun—named after the rebel general’s emblem, a white sun outlined in red, rather than the nearby stars—it had been designated an ashway, where permanent habitation was forbidden.

  More important to Lisse, however, was the fact that 514 was the ashway nearest the last mercenary sighting, some five years ago. As a student, she had learned the names and silhouettes of the most prominent war-kites, and set verses of praise in their honor to Imperial anthems. She had written essays on their tactics and memorized the names of their most famous commanders, although there were no statues or portraits, only the occasional unsmiling photograph. The Imperium was fond of statues and portraits.

  For a hundred years (administrative calendar), the mercenaries had served their masters unflinchingly and unfailingly. Lisse had assumed that she would have as much time as she needed to plot against them. Instead, they had broken their service, for reasons the Imperium had never released—perhaps they didn’t know, either—and none had been seen since.

  “I’m not sure there’s anything to find here,” Lisse said. Surely the Imperium would have scoured the region for clues. The tapestries were empty of ravens. Instead, they diagrammed shifting voidcurrent flows. The approach of enemy starflyers would perturb the current and allow Lisse and the ghost to estimate their intent. Not trusting the kite’s systems—although there was only so far that she could take her distrust, given the circumstances—she had been watching the tapestries for the past several hours. She had, after a brief argument with the ghost, switched on haptics so that the air currents would, however imperfectly, reflect the status of the void around them. Sometimes it was easier to feel a problem through your skin.

  “There’s no indication of derelict kites here,” she added. “Or even kites in use, other than this one.”

  “It’s a starting place, that’s all,” the ghost said.

  “We’re going to have to risk a station eventually. You might not need to eat, but I do.” She had only been able to sneak a few rations out of base. It was tempting to nibble at one now.

  “Perhaps there are stores on the kite.”

  “I can’t help but think this place is a trap.”

  “You have to eat sooner or later,” the ghost said reasonably. “It’s worth a look, and I don’t want to see you go hungry.” At her hesitation, it added, “I’ll stand watch here. I’m only a breath away.”

  This didn’t reassure her as much as it should have, but she was no longer a child in a bunk precisely aligned with the walls, clutching the covers while the ghost told her her people’s stories. She reminded herself of her favorite story, in which a single sentinel kept away the world’s last morning by burning out her eyes, and set out.

  Lisse felt the ghostweight’s pull the farther away she walked, but that was old pain, and easily endured. Lights flicked on to accompany her, diffuse despite her unnaturally sharp shadow, then started illuminating passages ahead of her, guiding her footsteps. She wondered what the kite didn’t want her to see.

  Rations were in an unmarked storage room. She wouldn’t have been certain about the rations, except that they were, if the packaging was to be believed, field category 72: better than what she had eaten on training exercises, but not by much. No surprise, now that she thought about it: from all accounts, the mercenaries had relied on their masters’ production capacity.

  Feeling ridiculous, she grabbed two rations and retraced her steps. The fact that the kite lit her exact path only made her more nervous.

  “Anything new?” she asked the ghost. She tapped the ration. “It’s a pity that you can’t taste poison.”

  The ghost laughed dryly. “If the kite were going to kill you, it wouldn’t be that subtle. Food is food, Lisse.”

  The food was as exactingly mediocre as she had come to expect from military food. At least it was not any worse. She found a receptacle for disposal afterward, then laid out a Scorch tableau, Candle column to Bone, right to left. Cards rather than jerengjen, because she remembered the scuttling hound-jerengjen with creeping distaste.

  From the moment she left Base 87, one timer had started running down. The devastation of Ishuel’s Bridge had begun another, the important one. She wasn’t gambling her survival; she had already sold it. The question was, how many Imperial bases could she extinguish on her way out? And could she hunt down any of the mercenaries that had been the Imperium’s killing sword?

  Lisse sorted rapidly through possible targets. For instance, Base 226 Mheng, the Petaled Fortress. She would certainly perish in the attempt, but the only way she could better that accomplishment would be to raze the Imperial firstworld, and she wasn’t that ambitious. There was Bridgepoint 663 Tsi-Kes, with its celebrated Pallid Sentinels, or Aerie 8 Yeneq, which built the Imperium’s greatest flyers, or—

  She set the cards down, closed her eyes, pressed her palms against her face. She was no tactician supreme. Would it make much difference if she picked a card at random?

  But of course nothing was truly random in the ghost’s presence.

  She laid out the Candle Column again. “Not 8 Yeneq,” she said. “Let’s start with a softer target. Aerie 586 Chiu.”

  Lisse looked at the ghost: the habit of seeking its approval had not left her. It nodded. “The safest approach is via the Capillary Ashways. It will test your piloting skills.”

  Privately, Lisse thought that the kite would be happy to guide itself. They didn’t dare allow it to, however.

  The Capillaries were among the worst of the ashways. Even starlight moved in unnerving ways when faced with ancient networks of voidcurrent gates, unmaintained for generations, or vortices whose behavior changed day by day.

  They were fortunate with the first several capillaries. Under other circumstances, Lisse would have gawked at the splendor of lensed galaxies and the jewel-fire o
f distant clusters. She was starting to manipulate the control interface without hesitating, or flinching as though a wolf’s shadow might cross hers.

  At the ninth—

  “Patrol,” the ghost said, leaning close.

  She nodded jerkily, trying not to show that its proximity pained her. Its mouth crimped in apology.

  “It would have been worse if we’d made it all the way to 586 Chiu without a run-in,” Lisse said. That kind of luck always had a price. If she was unready, best to find out now, while there was a chance of fleeing to prepare for a later strike.

  The patrol consisted of sixteen flyers: eight Lance 82s and eight Scout 73s. She had flown similar Scouts in simulation.

  The flyers did not hesitate. A spread of missiles streaked toward her. Lisse launched antimissile fire.

  It was impossible to tell whether they had gone on the attack because the Imperium and the mercenaries had parted on bad terms, or because the authorities had already learned of what had befallen Rhaion. She was certain couriers had gone out within moments of the devastation of Ishuel’s Bridge.

  As the missiles exploded, Lisse wrenched the kite toward the nearest vortex. The kite was a larger and sturdier craft. It would be better able to survive the voidcurrent stresses. The tapestries dimmed as they approached. She shut off haptics as wind eddied and swirled in the command spindle. It would only get worse.

  One missile barely missed her. She would have to do better. And the vortex was a temporary terrain advantage; she could not lurk there forever.

  The second barrage came. Lisse veered deeper into the current. The stars took on peculiar roseate shapes.

  “They know the kite’s capabilities,” the ghost reminded her. “Use them. If they’re smart, they’ll already have sent a courier burst to local command.”

  The kite suggested jerengjen flyers, harrier class. Lisse conceded its expertise.

  The harriers unfolded as they launched, sleek and savage. They maneuvered remarkably well in the turbulence. But there were only ten of them.

  “If I fire into that, I’ll hit them,” Lisse said. Her reflexes were good, but not that good, and the harriers apparently liked to soar near their targets.

  “You won’t need to fire,” the ghost said.

  She glanced at him, disbelieving. Her hand hovered over the controls, playing through possibilities and finding them wanting. For instance, she wasn’t certain that the firebird (explosives) didn’t entail self-immolation, and she was baffled by the stag.

  The patrol’s pilots were not incapable. They scorched three of the harriers. They probably realized at the same time that Lisse did that the three had been sacrifices. The other seven flensed them silent.

  Lisse edged the kite out of the vortex. She felt an uncomfortable sense of duty to the surviving harriers, but she knew they were one-use, crumpled paper, like all jerengjen. Indeed, they folded themselves flat as she passed them, reducing themselves to battledrift.

  “I can’t see how this is an efficient use of resources,” Lisse told the ghost.

  “It’s an artifact of the mercenaries’ methods,” it said. “It works. Perhaps that’s all that matters.”

  Lisse wanted to ask for details, but her attention was diverted by a crescendo of turbulence. By the time they reached gentler currents, she was too tired to bring it up.

  They altered their approach to 586 Chiu twice, favoring stealth over confrontation. If she wanted to char every patrol in the Imperium by herself, she could live a thousand sleepless years and never be done.

  For six days they lurked near 586 Chiu, developing a sense for local traffic and likely defenses. Terrain would not be much difficulty. Aeries were built near calm, steady currents.

  “It would be easiest if you were willing to take out the associated city,” the ghost said in a neutral voice. They had been discussing whether making a bombing pass on the aerie posed too much of a risk. Lisse had balked at the fact that 586 Chiu Second City was well within blast radius. The people who had furnished the kite’s armaments seemed to have believed in surfeit. “They’d only have a moment to know what was happening.”

  “No.”

  “Lisse—”

  She looked at it mutely, obdurate, although she hated to disappoint it. It hesitated, but did not press its case further.

  “This, then,” it said in defeat. “Next best odds: aim the voidcurrent disrupter at the manufactory’s core while jerengjen occupy the defenses.” Aeries held the surrounding current constant to facilitate the calibration of newly built flyers. Under ordinary circumstances, the counterbalancing vortex was leashed at the core. If they could disrupt the core, the vortex would tear at its surroundings.

  “That’s what we’ll do, then,” Lisse said. The disrupter had a short range. She did not like the idea of flying in close. But she had objected to the safer alternative.

  Aerie 586 Chiu reminded Lisse not of a nest but of a pyre. Flyers and transports were always coming and going, like sparks. The kite swooped in sharp and fast. Falcon-jerengjen raced ahead of them, holding lattice formation for two seconds before scattering toward their chosen marks.

  The aerie’s commanders responded commendably. They knew the kite was by far the greater threat. But Lisse met the first flight they threw at her with missiles keen and terrible. The void lit up in a clamor of brilliant colors.

  The kite screamed when a flyer salvo hit one of its secondary wings. It bucked briefly while the other wings changed their geometry to compensate. Lisse could not help but think that the scream had not sounded like pain. It had sounded like exultation.

  The real test was the gauntlet of Banner 142 artillery emplacements. They were silver-bright and terrible. It seemed wrong that they did not roar like tigers. Lisse bit the inside of her mouth and concentrated on narrowing the parameters for the voidcurrent disrupter. Her hand was a fist on the control panel.

  One tapestry depicted the currents: striations within striations of pale blue against black. Despite its shielding, the core was visible as a knot tangled out of all proportion to its size.

  “Now,” the ghost said, with inhuman timing.

  She didn’t wait to be told twice. She unfisted her hand.

  Unlike the wolf-strike, the disrupter made the kite scream again. It lurched and twisted. Lisse wanted to clap her hands over her ears, but there was more incoming fire, and she was occupied with evasive maneuvers. The kite folded in on itself, minimizing its profile. It dizzied her to view it on the secondary tapestry. For a panicked moment, she thought the kite would close itself around her, press her like petals in a book. Then she remembered to breathe.

  The disrupter was not visible to human sight, but the kite could read its effect on the current. Like lightning, the disrupter’s blast forked and forked again, zigzagging inexorably toward the minute variations in flux that would lead it toward the core.

  She was too busy whipping the kite around to an escape vector to see the moment of convergence between disrupter and core. But she felt the first lashing surge as the vortex spun free of its shielding, expanding into available space. Then she was too busy steadying the kite through the triggered subvortices to pay attention to anything but keeping them alive.

  Only later did she remember how much debris there had been, flung in newly unpredictable ways: wings torn from flyers, struts, bulkheads, even an improbable crate with small reddish fruit tumbling from the hole in its side.

  Later, too, it would trouble her that she had not been able to keep count of the people in the tumult. Most were dead already: sliced slantwise, bone and viscera exposed, trailing banners of blood; others twisted and torn, faces ripped off and cast aside like unwanted masks, fingers uselessly clutching the wrack of chairs, tables, door frames. A fracture in one wall revealed three people in dark green jackets. They turned their faces toward the widening crack, then clasped hands before a subvortex hurled them apart. The last Lisse saw of them was two hands, still clasped together and severed at the wrist.


  Lisse found an escape. Took it.

  She didn’t know until later that she had destroyed 40% of the aerie’s structure. Some people survived. They knew how to rebuild.

  What she never found out was that the disrupter’s effect was sufficiently long-lasting that some of the survivors died of thirst before supplies could safely be brought in.

  In the old days, Lisse’s people took on the ghostweight to comfort the dead and be comforted in return. After a year and a day, the dead unstitched themselves and accepted their rest.

  After Jerengjen Day, Lisse’s people struggled to share the sudden increase in ghostweight, to alleviate the flickering terror of the massacred.

  Lisse’s parents, unlike the others, stitched a ghost onto a child.

  “They saw no choice,” the ghost told her again and again. “You mustn’t blame them.”

  The ghost had listened uncomplainingly to her troubles and taught her how to cry quietly so the teachers wouldn’t hear her. It had soothed her to sleep with her people’s legends and histories, described the gardens and promenades so vividly she imagined she could remember them herself. Some nights were more difficult than others, trying to sleep with that strange, stabbing, heartpulse ache. But blame was not what she felt, not usually.

  The second target was Base 454 Qo, whose elite flyers were painted with elaborate knotwork, green with bronze-tipped thorns. For reasons that Lisse did not try to understand, the jerengjen disremembered the defensive flight but left the painted panels completely intact.

  The third, the fourth, the fifth—she started using Scorch card values to tabulate the reported deaths, however unreliable the figures were in any unencrypted sources. For all its talents, the kite could not pierce military-grade encryption. She spent two days fidgeting over this inconvenience so she wouldn’t have to think about the numbers.

  When she did think about the numbers, she refused to round up. She refused to round down.

  The nightmares started after the sixth, Bridgepoint 977 Ja-Esh. The station commander had kept silence, as she had come to expect. However, a merchant coalition had broken the interdict to plead for mercy in fourteen languages. She hadn’t destroyed the coalition’s outpost. The station had, in reprimand.
