The Stone Sky

  “Not so lucky.” He touches the nape of his neck. The bright, nerve-etched network of searing light within him is still active—hurting him, driving at him, trying to break him. At the center of that web is the shard of corestone that someone put into him. For the first time, Nassun wonders how it was put into him. She thinks about the long, ugly scar down the back of his neck, which she thinks he keeps his hair long to cover. She shivers a little with the implications of that scar.

  “I don’t—” Nassun tries to drag her thoughts away from the image of Schaffa screaming while someone cuts him. “I don’t understand Guardians. The other kind of Guardian, I mean. I don’t … They’re awful.” And she cannot even begin to imagine Schaffa being like them.

  He doesn’t reply for a while, as they chew through their meal. Then, softly, he says, “The details are lost to me, and the names, and most of the faces. But the feelings remain, Nassun. I remember that I loved the orogenes to whom I was Guardian—or at least, I believed that I loved them. I wanted them to be safe, even if that meant inflicting small cruelties to hold the greater at bay. Anything, I felt, was better than genocide.”

  Nassun frowns. “What’s genocide?”

  He smiles again, but it is sad. “If every orogene is hunted down and slain, and if the neck of every orogene infant born thereafter is wrung, and if every one like me who carries the trait is killed or effectively sterilized, and if even the notion that orogenes are human is denied … that would be genocide. Killing a people, down to the very idea of them as a people.”

  “Oh.” Nassun feels queasy again, inexplicably. “But that’s …”

  Schaffa inclines his head, acknowledging her unspoken But that’s what’s been happening. “This is the task of the Guardians, little one. We prevent orogeny from disappearing—because in truth, the people of the world would not survive without it. Orogenes are essential. And yet because you are essential, you cannot be permitted to have a choice in the matter. You must be tools—and tools cannot be people. Guardians keep the tool … and to the degree possible, while still retaining the tool’s usefulness, kill the person.”

  Nassun stares back at him, understanding shifting within her like an out-of-nowhere niner. It is the way of the world, but it isn’t. The things that happen to orogenes don’t just happen. They’ve been made to happen, by the Guardians, after years and years of work on their part. Maybe they whispered ideas into the ears of every warlord or Leader, in the time before Sanze. Maybe they were even there during the Shattering—inserting themselves into ragged, frightened pockets of survivors to tell them who to blame for their misery, and how to find them, and what to do with the culprits found.

  Everybody thinks orogenes are so scary and powerful, and they are. Nassun is pretty sure she could wipe out the Antarctics if she really wanted, though she would probably need the sapphire to do it without dying. But despite all her power, she’s still just a little girl. She has to eat and sleep like every other little girl, among people if she hopes to keep eating and sleeping. People need other people to live. And if she has to fight to live, against every person in every comm? Against every song and every story and history and the Guardians and the militia and Imperial law and stonelore itself? Against a father who could not reconcile daughter with rogga? Against her own despair when she contemplates the gargantuan task of simply trying to be happy?

  What can orogeny do against something like that? Keep her breathing, maybe. But breathing doesn’t always mean living, and maybe … maybe genocide doesn’t always leave bodies.

  And now she is more certain than ever that Steel was right.

  She looks up at Schaffa. “Till the world burns.” It’s what he said to her, when she told him what she meant to do with the Obelisk Gate.

  Schaffa blinks, then smiles the tender, awful smile of a man who has always known that love and cruelty are two faces of the same coin. He pulls her close and kisses her forehead, and she hugs him tight, so very glad to have one parent, at last, who loves her as he should.

  “Till the world burns, little one,” he murmurs against her hair. “Of course.”

  In the morning, they resume walking down the winding stair.

  The first sign of change is the appearance of another railing on the other side of the stairwell. The railing itself is made of strange stuff, bright gleaming metal not marred at all by verdigris or tarnish. Now, though, there are twin railings, and the stairwell widens enough that two people can walk abreast. Then the winding stairwell begins to unwind—still descending at the same angle, but less and less curved, until finally it extends straight ahead, into darkness.

  After an hour or so of walking, the tunnel suddenly opens out, walls and roof vanishing. Now they descend along a trail of lighted, linked stairs that are completely unsupported, somehow, in open air. The stairs should not be possible, held up as they are by nothing but the railing and, apparently, each other—but there is no judder or creak as Nassun and Schaffa walk down. Whatever the stuff that comprises the steps is, it’s much stronger than ordinary stone.

  And now they’re descending into a massive cavern. It’s impossible to see how large it is in the darkness, although shafts of illumination slant down from occasional circles of cool white light that dot the cavern’s ceiling at irregular intervals. The light illuminates … nothing. The cavern’s floor is a vast expanse of empty space filled with irregular, lumpen piles of sand. But now that they are within what Nassun once thought was an empty magma chamber, she can sess things more clearly, and all at once she realizes just how wrong she was.

  “This isn’t a magma chamber,” she tells Schaffa in an awed tone. “It wasn’t a cavern at all when this city was built.”

  “What?”

  She shakes her head. “It wasn’t enclosed. It must have been … I don’t know? Whatever’s left when a volcano blows up completely.”

  “A crater?”

  She nods quickly, excited with the realization. “It was open to the sky then. People built the city in the crater. But then there was another eruption, right in the middle of the city.” She points ahead of them, into the dark; the stairwell is going right toward what she sesses is the epicenter of this ancient destruction.

  But that can’t be right. Another eruption, depending on the type of lava, should simply have destroyed the city and filled the old crater. Instead, somehow, all the lava went up and over the city, spreading out like a canopy and solidifying over it to form this cavern. Leaving the city within the crater more or less intact.

  “Impossible,” Schaffa says, frowning. “Not even the most viscous lava would behave that way. But …” His expression clouds. Again he is trying to sift through memories truncated and trimmed, or perhaps simply dimmed by age. On impulse Nassun grabs his hand, to encourage him. He glances at her, smiles absently, and resumes frowning. “But I think … an orogene could do such a thing. It would take one of rare power, however, and probably the aid of an obelisk. A ten-ringer. At least.”

  Nassun frowns in confusion at this. The gist of what he’s said fits, though: Someone did this. Nassun looks up at the ceiling of the cavern and realizes belatedly that what she thought were odd stalactites are actually—she gasps—the leftover impressions of buildings that are no longer there! Yes, there is a narrowing point that must have been a spire; here a curving arch; there a geometric strangeness of spokes and curves that looks oddly organic, like the under-ribs of a mushroom cap. But while these imprints fossil all over the ceiling of the cavern, the solidified lava itself stops a few hundred feet above the ground. Belatedly, Nassun realizes that the “tunnel” from which they emerged is also the remains of a building. Looking back, she sees that the outside of the tunnel looks like one of the cuttlebones that her father once used for fine knapping work—more solid, and made from the same strange white material as the slab up on the surface. That must have been the top of the building. But a few feet below where the canopy ends, the building does, too, to be replaced by this strange white stair.
That must have been done sometime after the disaster—but how? And by whom? And why?

  Trying to understand what she’s seeing, Nassun looks more closely at the cavern’s floor. The sand is mostly pale, though there are mottling patches of darker gray and brown laced throughout. In a few places, twisted lengths of metal or immense broken fragments of something larger—other buildings, maybe—poke through the sand like bones from a half-unearthed grave.

  But this is wrong, too, Nassun realizes. There isn’t enough material here to be the remnants of a city. She hasn’t seen many deadciv ruins, or cities for that matter, but she’s read about them and heard stories. She’s pretty sure that cities are supposed to be full of stone buildings and wooden storecaches and maybe metal gates and cobbled streets. This city is nothing, relatively speaking. Just metal and sand.

  Nassun puts down her hands, which she’s raised without thinking while her fleshless senses flicker and search. Inadvertently she glances down, which makes the distance between the stair she stands on and that sandy cavern floor yawn and seem to stretch. This makes her step back closer to Schaffa, who puts a reassuring hand on her shoulder.

  “This city,” Schaffa says. She glances at him in surprise; he looks thoughtful. “There is a word in my mind, but I don’t know what it is. A name? Something that holds meaning in another language?” He shakes his head. “But if this is the city I think it is, I have heard tales of its grandeur. Once, they say, this city held billions of people.”

  That seems impossible. “In one city? How big was Yumenes?”

  “A few million.” He smiles at her openmouthed gape, then sobers somewhat. “And now there can’t be many more people than that, altogether, across the whole of the Stillness. When we lost the Equatorials, we lost the bulk of humanity. Still. Once, the world was even bigger.”

  It can’t be. The volcanic crater is only so vast. And yet … Delicately, Nassun sesses below the sand and debris, searching for evidence of the impossible. The sand is much deeper than she thought. Far beneath its surface, though, she finds pressed pathways in long, straight lines. Roads? Foundations, too, though they are in oblong and round and other odd shapes: hourglass loops and fat S-curves and bowl-shaped dips. Not a single square. She puzzles over the odd composition of these foundations, and then abruptly realizes that it all has the sess of something mineralized, alkaline. Oh, it’s petrifying! Which means that originally—Nassun gasps.

  “It’s wood,” she blurts aloud. A building foundation of wood? No, it’s something like wood, but also a bit like the polymer stuff that her father used to make, and a little like the strange not-stone of the stair they’re standing on. All the roads she can sess are something similar. “Dust. Everything down there, Schaffa. It’s not sand, it’s dust! It’s plants, lots of them, dead so long ago that it’s all just dried up and crumbled away. And …” Her gaze is drawn back up to the lava canopy overheard. What must it have been like? The whole cavern lit up in red. The air too hot to breathe. The buildings lasted longer, long enough for the lava to start to cool around them, but every person in this city would have roasted within the first few hours of being buried under a bubble of fire.

  That’s what’s in the sand, too, then: countless people, cooked into char and crumbled away.

  “Intriguing,” Schaffa says. He leans on the railing, heedless of the distance to the ground as he gazes out over the cavern. Nassun’s belly clenches in fear for him. “A city built of plants.” Then his gaze sharpens. “But nothing’s growing here now.”

  Yes. That’s the other thing Nassun has noticed. She’s traveled enough now, and seen enough other caves to know that this place should be teeming with life, like lichens and bats and blind white insects. She shunts her perception into the realm of the silver, searching for the delicate lines that should be everywhere amid so much living detritus. She finds them, lots of them, but … Something is strange. The lines flow together and focus, tiny threads becoming thicker channels—much like the way magic flows within an orogene. She’s never seen this happen in plants or animals or soil before. These more concentrated flows come together and continue forward—the direction in which the stairway is going. She follows them well past the stairway she can see, thickening, brightening … and then somewhere ahead, they abruptly stop.

  “Something bad is here,” Nassun says, her skin prickling. Abruptly she stops sessing. She does not want to sess what’s ahead, for some reason.

  “Nassun?”

  “Something is eating this place.” She blurts the words, then wonders why she’s said them. But now that she’s said it, she feels like it was the right thing to say. “That’s why nothing grows. Something is taking all the magic away. Without that, everything’s dead.”

  Schaffa regards her for a long moment. One of his hands, Nassun sees, is on the hilt of his black glass poniard, where it’s strapped against his thigh. She wants to laugh at this. What’s ahead isn’t something he can stab. She doesn’t laugh because it’s cruel, and because she’s suddenly so scared that if she starts laughing, she might not stop.

  “We don’t have to go forward,” Schaffa suggests. It is gentle, and badly needed reassurance that he will not lose respect for her if she abandons her mission out of fear.

  It bothers Nassun, though. She has her pride. “N-no. Let’s keep going.” She swallows hard. “Please.”

  “Very well, then.”

  They proceed. Someone or something has dug a channel through the dust, beneath and around the impossible stair. As they continue to descend, they pass mountains of the stuff. Presently, though, Nassun sees another tunnel looming ahead. This one is set against the floor of the cavern—at last—and its mouth is immense. Concentric arches, each carved from marble in different shades, loom high overhead as the stairway finally reaches the ground and flattens into the surrounding stones. The tunnel narrows further in; there’s only darkness beyond. The floor of the entryway is something that looks like lacquer, tiled in gradient shades of blue and black and dark red. It is rich and lovely color, a relief to the eyes after so much white and gray, and yet it, too, is impossibly strange. Somehow, none of the city’s dust has blown or subsided into this entryway.

  Dozens of people could pass through that archway. Hundreds in a minute. Now, however, only one stands here, watching them from under a band of rose marble that contrasts sharply against his paler, colorless lines. Steel.

  He doesn’t move as Nassun walks over to him. (Schaffa comes over, too, but he is slower, tense.) Steel’s gray gaze is fixed on an object beside him that is not familiar to Nassun but which would be to her mother: a hexagonal plinth rising from the floor, like a smoky quartz crystal shaft that has been sheared off halfway. Its topmost surface is at a slight angle. Steel’s hand is held toward it in a gesture of presentation. For you.

  So Nassun focuses on the plinth. She reaches toward it and jerks back as something lights up around its rim before her fingers can touch the slanted surface. Bright red marks float in the air above the crystal, etching symbols into empty space. She cannot fathom their meaning, but the color unnerves her. She looks up at Steel, who has not moved and looks as if he’s been in the same position since this place was built. “What does it say?”

  “That the transport vehicle I told you about is currently nonfunctional,” says the voice from within Steel’s chest. “You’ll need to power and reboot the system before we can use this station.”

  “‘R-re … boot?’” She tries to figure out what putting on boots has to do with ancient ruins, then decides to run with the part she understands. “How do I give it power?”

  Abruptly, Steel is in a different position, facing the archway that leads deeper into the station. “Go inside and provide power at the root. I’ll stay here and key in the start-up sequence once there’s enough power.”

  “What? I don’t—”

  His gray-on-gray eyes shift over to her. “You’ll see what to do inside.”

  Nassun chews on the inside of her cheek
, looking into the archway. It’s really dark in there.

  Schaffa’s hand touches her shoulder. “I’ll go with you, of course.”

  Of course. Nassun swallows and nods, grateful. Then she and Schaffa walk into the dark.

  It doesn’t stay dark for long. Like on the white stair, small panels of light begin glowing along the sides of the tunnel as they progress. The lights are dim, and yellowy in a way that suggests age, weathering, or … well, or weariness. That’s the word that pops into Nassun’s head for some reason. The light is enough to glimmer off the edges of the tiles beneath their feet. There are doors and alcoves along the tunnel walls, and at one point Nassun spots a strange contraption jutting out about ten feet up. It looks like … a wagon bed? Without wheels or a yoke, and as if that wagon bed was made of the same smooth material as the stair, and as if that wagon bed ran along some kind of track set into the wall. It seems obviously made to transport people; maybe it’s how people who couldn’t or wouldn’t walk got around? Now it is still and dark, locked to the wall forever where its last driver left it.

  They notice the peculiar bluish light illuminating the tunnel up ahead, but that still isn’t adequate warning enough to prepare them for when the path suddenly curves left, and they find themselves in a new cavern. This much smaller cavern isn’t full of dust, or at least not much of it. What it does contain, instead, is a titanic column of solid blue-black volcanic glass.

  The column is huge, and irregular, and impossible. Nassun just stares, openmouthed, at this thing that fills nearly the whole cavern, ground to ceiling and beyond. That it is the solidified, rapidly cooled product of what must have been a titanic explosion is immediately obvious. That it is somehow the source of the lava canopy which flowed into the adjoining cavern is equally indisputable.

  “I see,” Schaffa says. Even he sounds overwhelmed, his voice softened by awe. “Look.” He points down. This is what finally provides Nassun the focal point to establish perspective, and size, and distance. The thing is huge, because now she can see tiers that descend toward its base, ringing it in concentric octagons. Three of them. On the outermost tier are buildings, she thinks. They’re badly damaged, half fallen in, just shells, but she sesses at once why they still exist where the ones in the cavern beyond have crumbled. The heat that must have filled this cavern has metamorphized something in the buildings’ construction, hardening and preserving them. Some sort of concussion has done damage, too: All the buildings are torn open on the same side, facing the great glass column. Looking from what she guesses is a three-story building to the glass column, she guesstimates that the column is not as far away as it looks; it’s just much bigger than she initially guessed. The size of … oh.
