The Siren Depths

Chapter Nineteen

Moon fell into Jade’s arms, and she whipped away from the cliff so fast it took his breath. She crossed the narrow canyon, landed on a sharp slope, and slid down to firmer footing on a ledge. She set Moon on his feet but didn’t let go of his waist; her scent washed over him, clean and welcome. He leaned into her warmth, the relief so heady it made his knees weak.

From this angle he could see that the dark shape with claws sunk deep into the kethel’s back was Stone. He had bitten down into the creature’s neck, cracking through its armor plates. The kethel thrashed again, its tail lashed, and it slid further down the slope.

The abrupt change of fortune had scattered all Moon’s thoughts and half-formed plans. All he wanted to do was stand here and hold on to Jade, but he made himself try to catch up. “Celadon escaped?” She must have, for Jade and Stone to have followed so quickly behind the sac.

“Yes, with Delin and four of her warriors.” Jade took his chin and turned his head to face her, looking into his eyes with a sharp intensity. “Are you all right?”

“Yes.” It was also a relief not to have to lie. “It was Shade they wanted. The progenitor and the rulers took him somewhere. I sent Floret after him when the fire started. Chime’s all right, too. Root and Song are alive but hurt.”

Jade released his chin and his gaze with a hiss of relief. “When I saw the sac catch on fire, I knew it had to be you and Chime.” She raised her voice to yell, “Stone, stop playing with that thing and finish it!”

Stone’s snarl echoed off the canyon. With his teeth still clamped in the kethel’s throat, he slid his claws forward and into the space under the kethel’s armored collar. He jerked his hands down and twisted his head, and black blood fountained out and down the cliffside. The kethel struggled wildly and dragged Stone down the rocks and almost over the ledge Moon had been trapped on.

Moon told her, “The flying boat—”

“We found it before we found you. The others are there now.”

“How did you get here so fast?”

“We left the warriors and Delin behind to warn Opal Night, and Stone flew as fast as he could, carrying me and Celadon and the other queens. When he had to rest, he shifted and one of us carried him. We stopped only to eat.” Jade added with more than a trace of wryness, “Malachite kept up on her own.”

“Malachite kept up with Stone?”

“Yes.” Jade bared her teeth, an unconscious grimace of irritation. “Your mother is sustained by pure rage. Why did the Fell want Shade?”

The kethel’s struggles grew weaker, turned into death throes. Stone released his grip and the kethel tumbled down, bounced off rocky protrusions and ledges, then plunged toward the bottom of the gorge. Moon answered, “They’re following a voice, something that they can hear but we can’t. It’s been telling them to come to some place along this coast. It told them it wanted a crossbreed consort; we’re not sure why.”

Jade growled in a combination of anger and dismay. “Is that what this was about?”

“I think—” Moon sensed movement above just as Jade dropped him and snarled a warning. He flared his spines and crouched. Two rulers and a cluster of dakti arrowed down toward them.

Moon had time to think they were in a bad spot, they wouldn’t make it into the air before the Fell hit them. Then something large and dark green whipped down out of nowhere to slap the first ruler out of the air and strike the second in mid-dive. Belatedly, Moon realized it was Malachite.

Her dark green scales were almost black in the daylight and her spines rippled in the sea wind. Moon hadn’t seen her outside the confines of the colony before, and it was a shock to see her now. In the wind, she was all predator.

Malachite landed on the rounded boulder above them and ripped her claws through the ruler, blood spraying as she tore his head off. The second ruler flapped out of control and slammed into the slope to the side of the boulder. Jade pounced and flattened him to the rock. Moon braced himself to spring up and take on the dakti, but Malachite tore two of them out of the air before he could unfurl his wings. Rock crunched below them as Stone scrambled up onto a lower ledge, and the rest of the dakti fled in shrieking terror.

Malachite shook the blood off her spines and turned to Jade and the last ruler. Moon said, “Wait! Ask him where the progenitor took Shade.”

Malachite’s spines rattled in fury. She reached down, seized the ruler by the throat, and yanked him up as Jade pulled away. Malachite shook the ruler. Her voice was hard and cold, too controlled to be a snarl. “Where is the other consort?”

The ruler was dazed, his chest ripped by Jade’s claws and the swipe that had knocked him out of the air. He growled weakly, and Malachite set a claw tip to his right eye. She said, “The others sent you out here to die, and die you will. Slowly, or quickly.”

Moon saw the ruler’s body quiver, and remembered what Malachite had said about the Fell: that their instinctive obedience to the female progenitors could be used against them. Almost as if the words were being drawn out against its will, it said, “An island. Not far.”

Malachite squeezed, snapped its neck, then ripped its head off and tossed it and the body down the slope.

Jade’s spines rippled in pure exasperation. She said, “You could have asked it which island!”

Malachite’s tail lashed. She said, “They always lie on the second question.” Her gaze was on the sky, but the shape flying toward them was Chime, carrying Lithe.

Malachite settled into a crouch as Chime landed awkwardly on the far side of the boulder. He and Lithe scrambled around to a perch above Moon and Jade. Chime looked frightened but determined and Lithe just looked determined. She told Moon, “We thought you’d need our help to look for Shade.”

Malachite’s attention turned to the retreating sac, which was just coming into view again past one of the pointed peaks. The kethel supporting it had finally gotten organized enough to head along the cliffs. Occupied as they were, they didn’t give any sign that they had seen the fate of the kethel or the rulers who had come after Moon. If they had any sense they were looking for a section of beach wide enough to set the sac down so the fire in the bottom could be dealt with. Malachite tilted her head toward Moon. She said, “You’re unhurt?”

“Yes. Did they tell you what happened?”

Malachite’s spines dipped in assent. Still without looking down, she said, “Go to the flying ship, line-grandfather. Guard it with Celadon and the others.”

Stone growled and lashed his tail. Jade said, “She’s right. You’re exhausted.”

Moon didn’t think that would do it. He added, “Song and Root are wounded, with Ivory and her warriors. If the Fell find the boat, Celadon is going to need help.”

Stone’s grumbling response rumbled through the rock. Moon interpreted it as meaning that Stone wasn’t happy, but he knew they were right. Then Stone flung himself backward in a spray of pebbles and loose rubble, caught the rising wind in the gorge, and flapped inland.

Malachite said, “Moon, go with him.”

“No.” Moon didn’t intend to argue this point. “Not until I can take Shade with me.”

Malachite didn’t respond except with a spine ripple that Moon couldn’t interpret. Jade hissed in frustration. She clearly wanted to send Moon to the boat, but the idea of siding with Malachite on any point involving him was too painful to contemplate. Moon got the idea that the only good thing about the frantic pace of the race after the sac was that none of the rescuers had had much chance to speak to each other.

With no warning, Malachite sprang into flight. Jade snarled, “I suppose she wants us to follow her,” and jumped off the ledge to take to the air. Chime grabbed Lithe and he and Moon scrambled to follow.

Moon flew even with Chime to shout, “I can take Lithe. You go back.”

“No.” Chime sounded as if he was holding onto his resolve with effort. “I heard that voice once. Maybe I can help, like what happened on the leviathan.”

Moon thought he was right, but he had wanted to give Chime the option to retreat. None of them knew what they would be facing.

As they drew near the cliffs above the rocky beach, Moon looked for the sac. It was some distance down the coast now, and the kethel were lowering it toward a relatively flat section of beach that was heavily washed by waves. The bulge of the sac scraped against the cliff and it was still releasing a plume of dark smoke. If the Fell managed to lower the sac into the surf, they wouldn’t have long until the fire was under control; depending on whatever orders the progenitor had left, they might come looking for vengeance soon.

Moon heard a shout from ahead and looked toward the sea just as a familiar scent arrived on the wind. A shape with the bright scales of a warrior flew toward them from the array of islands just off the coast. Floret spotted them and circled, indicating that they should follow her.

Floret led them far out into the water to a rocky collection of spires. Moon landed on a damp, salt-encrusted rock below Jade, using his claws to keep from sliding down, and climbed up after the others to an uneven ledge along one of the peaks. Floret said, “Am I glad to see you all!” She pointed. “The Fell went there.”

It was a tall island several hundred paces away, an uneven dome of rock covered with heavy greenery, standing high above the water. It was mostly vertical, made up of cliffs and steep slopes covered with trees and clinging vines. There was no beach built up around it; the waves crashed directly against stony cliffs. At the very top, water gleamed through the fern trees, spilling down one of the cliffs to vanish in the jungle.

Floret continued, “They flew to the top, near where the waterfall comes out, then went into the jungle. I waited a while, then flew over, but I couldn’t get sight or scent of them. It was like they went into the rock somehow, but I couldn’t see any caves.” She dropped her spines in chagrin. “I’m afraid they left, and I didn’t see them.”

“You didn’t have much time to search,” Jade said. “They could be there somewhere.”

Moon said, “Lithe, is this the place you saw?”

Hanging on to Chime, Lithe shaded her eyes to study the island. She grimaced. “I saw trees growing on cliffs, saltwater and rock, and crashing waves. But that description fits most of these islands.”

“Where is that water coming from?” Chime muttered.

Jade asked, “What do you mean?”

“If it’s fresh, there has to be a spring, a well, pushing it up through the rock. If it’s saltwater, what’s pushing it?” He glanced around and saw the queens staring at him. His spines flattened defensively. “I just think it looks odd.”

But Malachite said, “As if it’s not natural.”

Chime nodded, relieved that she understood. “Yes, that.”

Malachite crouched and sprang into the air, her claws leaving jagged scrapes in the rock. Jade protested, “We need to talk about—Damn it!”

Moon twitched with the urge to hurry, but made himself wait for Jade. Chime groaned and said, “I hope I’m not wrong.”

Jade just growled in her throat and followed Malachite, and Moon, Chime, and Floret leapt after her.

Malachite had already circled over the island once and now dove down to land near the source of the waterfall. The foliage was so thick, Moon and the others had to land in the palms or ferny tops of the trees and clamber down. This surprised a number of large colorful tree crabs, which clacked their claws menacingly and skittered down the trunks, but Moon didn’t catch sight or scent of anything larger. There were traces of Fell stench on the leaves, caught when the Fell had brushed against them. He couldn’t pick out Shade’s more subtle scent.

The ground was covered with thick, low grass and flowers with heavy succulent stems. The waterfall was fairly narrow, only about twenty paces across at this point, and emerged from a slot in the bluff just above their heads. It tumbled across a mildly sloping space where there was barely room between the trees to walk, then dropped off the edge of a cliff to catch on another slope further down and disappear into the jungle again.

Malachite perched on a rock at the edge of the drop. “Floret, where did you search?”

Her voice blended with the falling water, pitched to cut through it but not be heard above it. Floret pointed toward the bluff. “Up there, because I thought they must have gone into a cave. But their scent was already faint.”

“As if they weren’t here long,” Jade said under her breath, and ducked under the low-hanging palms to scan the ground. Moon searched out from the waterfall, poking at the dirt under the grass and matted flower stems. The sea wind was blocked by the trees and the bluff, so if the Fell had lingered here at all, their scent should be much stronger. They didn’t just stop here briefly and leave, or Floret would have seen them. They might have climbed down through the jungle to the lower part of the island, but he thought the scent trails would indicate that.

Behind him, toward the waterfall, he heard Chime say, “This is fresh water. And that opening in the rock where it’s coming out is too square. Someone must have carved it.”

Moon started to turn back, but a flash caught his eye and he froze, focusing on it. It was a copper disk, lying amid the tree roots. Moon eased forward and picked it up. The incised image of a flower was clearly Arbora work and would have told him everything he needed to know, but he also recognized it. It had come off the anklet that Shade had been wearing.

He reached the waterfall again in a few long bounds, and held up the disk for Malachite to see. “Shade left a trail.”

They followed the path of scent traces and strategically dropped copper disks through the thick jungle. It led down the slope and around, toward the lower reaches of the rocky bluff behind the waterfall. Playing weak coddled young consort, Shade must have pretended to stumble and fall, long enough to snatch a handful of disks off the anklet.

Following the others through the greenery, Moon realized it might not have occurred to him to do the same in Shade’s position. Shade obviously took it as a given that Moon, or the warriors, or Malachite, or somebody would come after him, whether they arrived in time to save him or not. Moon would have just accepted the gut reaction that they would all think he was dead, dooming himself and leaving the queens no way to figure out where the Fell had gone and what they had been after. You have to work on that, he told himself.

The trail wound down through a nearly vertical gulley, shadowed by trees and heavy growth along its edge. The jungle was curiously quiet; insects hummed in the undergrowth but the birdcalls were distant, and Moon heard only a few rustles and clacks from the tree crabs. At the bottom of the gulley they went through a curtain of vines touched with Fell stench, and came out at the base of the rocky bluff that supported the waterfall.

For a moment it looked like a dead end. Then Moon realized the shadowed fold in the rock was a cave.

Jade reached it first and hissed with surprise. Moon arrived at her side in one bound, barely behind Malachite, with Floret, Chime, and Lithe after him.

It wasn’t a cave so much as an arch, curving to lead into an open well in the rock. In the well hung heavy chains supporting what had been a system of metal stairways, suspended out over the shaft. Several of them descended a hundred paces down to the deep shadowed entrance of a cavern at the bottom. Time and weather and maybe something else had broken a few of the chains and left some of the sections of stairway to hang in various precarious positions. They would have been unusable now by any species that weren’t skillful climbers. The verdigrised metal had been silvery at one point and chased with elaborate curling designs. An overhang shielded the shaft from overhead view, but let in daylight to gleam off the metal and the mineral streaks in the rock.

“So there were groundlings here at some point,” Moon muttered. It was another indication they were on the right track, but the right track to what?

Jade cocked her head to listen intently, and then tasted the air. “There’s seawater down there. But I don’t hear waves.”

Chime leaned out to look down the shaft. “So these were for bringing groundlings up from a harbor, somewhere down through there? But there’s nothing up here.”

Malachite caught one of the chains and swung out onto it. “The metal stinks of Fell,” she commented, and started to climb down.

Jade growled under her breath and sprang for another chain. “Floret, stay up here.”

Floret made a noise of protest in her throat, but quelled it at a dark look from Jade. Floret said, “If you don’t come back by nightfall, I follow you?”

“No, you find the flying boat and tell Stone what happened.” Jade began the climb down.

Lithe’s legs were a little too short to safely make the leap, so Moon leapt for a chain and then swung one of the others into her reach. She caught it and started down. With a worried shiver of his spines, Chime sprang after Moon. “At least we’re not in the sac anymore,” he said as they started down.

“Keep telling yourself that,” Moon said. He didn’t think the Fell had been called here by groundlings, even groundlings with the ability to get out to this island and construct these stairs.

“Be careful,” Floret said, leaning out to watch their progress.

They climbed down rapidly, following Malachite’s lead.

The opening to the cave was dank and cool, the air heavy with salt and the faint scent of rotting sea wrack. The sides were steep for some distance but then opened up gradually.

The chains stopped at a wide ledge in the wall, augmented by a rusted metal platform that had been attached to the rock with a complicated series of buttresses. Malachite already stood on it, and Jade dropped from the chain to land beside her.

Moon swung down off his chain, trying to take it all in. The faint daylight fell down on a series of ledges that stood out from the rock walls, studded by metal ladders, stairways, chains, all apparently designed to allow access further down into the cavern. Leaning out over the ledge, Moon saw dark water lap against rocks at the bottom. But he didn’t see any opening to the outside.

He also didn’t see, scent, or hear any sign of the Fell. They had apparently passed through this cavern on their way to somewhere else.

Lithe collected a couple of small rocks and concentrated until they emitted a soft glow of light. She handed one off to Chime to carry. Malachite leapt down to the next ledge, avoiding the rickety platform attached to it, and they followed her.

“There are carvings on these walls,” Jade pointed out, as she landed on another ledge.

Moon had noticed that too. They were too old and worn down to make much out of, but he could see straight lines and ovals and sharp angles that didn’t look at all like the curling floral designs on the rusted metal. “I think these used to be stone stairs, or something, that collapsed. The groundlings must have built all these metal ones to replace them.”

Lithe used a chain to help her swing across a gap that was a little too wide. “But how did these groundlings find this place?” she wondered. “If Floret hadn’t seen the Fell go to the island, if Shade hadn’t left a trail, we might never have found it.”

Chime said, “Maybe there was a city on the surface once, and the jungle grew over it.”

Moon felt a chill that had nothing to do with the deep still water. He paused and looked around again at the abandoned metal devices, the rusted tools scattered on the pathway. He realized the disintegrating leather oval that lay near his claws was a groundling shoe, cast aside in headlong flight. He said, “Or the groundlings were called here, like the Fell. And they ran away. Whatever they found, they ran away from it.”

They all went still for a moment, absorbing that idea. Even Malachite paused and tilted her head to consider it.

Jade hissed low under her breath. “After all the trouble they took to build these stairs… It must have been something terrible.”

“It can’t have killed them all,” Lithe said, her spines flicking uneasily. “We’d find more remains.”

Malachite leapt down to the next ledge. But she said, “Tell us exactly what you saw and heard from the Fell.”

As they climbed, Moon told them everything he remembered, trying to repeat it as close to verbatim as possible. When he was done he gave Chime a prod, and Chime nervously described what he had heard of the strange voice.

They were getting closer to the bottom of the cavern. The water didn’t smell stagnant, and there was enough movement in it to show that it was connected to the open sea somewhere. But the faded carving and the remnants of the original stone stairs went all the way down past the dark surface, the water lapping against them. Maybe the sea was shallower when they were built, Moon thought.

The last rusted metal stair curved into a deep alcove cut into the wall, ending on a smooth stone platform with steps that led down to vanish under the water. The Fell-stench was pronounced here, as if the Fell had spent some time on this platform.

Hanging from the curved roof of the alcove, suspended from more of the heavy chains, were several bell-shaped metal huts. The rock-lights Lithe and Chime carried reflected off the rusted metal, throwing huge shadows onto the cavern walls. Moon looked around, baffled. The trail clearly ended here.

He turned back to the huts. They looked a little like cargo lifters but were too small to take much of a load at one time. And the round sealed doors were too narrow for boxes and bales, but just right for an average-sized groundling to step through. He had a bad feeling about this.

Jade crouched to examine the edge of the platform, searching for traces that someone had passed this way. “So the Fell swam from here?” she asked, keeping her voice low. Chime and Lithe searched the dark corners of the platform, and Malachite stood still, listening for telltale splashes.

Moon saw the huts were suspended from a heavy metal beam that had been mounted to the old stone walls, and that it held chains and wheels and gears and other strange machinery, so verdigrised it was hard to tell one piece from the other. There were also dark green vines, twining around the chains, and growing down and through the roofs of each little hut. They all came from an odd plant covering the ceiling of the alcove. It looked like a fungus flower, covered with tiny white petals, spread to catch sustenance out of the damp air. This is new, Moon thought, baffled. It looked like the groundlings who had built the huts and the stairs had deliberately placed the vines this way.

Several sets of chains and vines led from the beam straight down into the water, as if those huts had dropped or been lowered below the surface. Some of them looked like they had been that way for turns, the chains encrusted with salt, the vines white and withered. But three sets of chains had had the rust scraped off in patches, as if they had recently been cranked along the beam, and the vines… Moon leaned out over the water to touch one. It was vibrating and making faint hissing noises.

Oh, you have to be joking… Moon stepped around and caught hold of a metal handle on the nearest hut. Jade came to help him, and Chime and Lithe stopped their futile search to watch.

With Jade holding the hut by one of the protrusions on its ribbed metal surface, Moon twisted the wheel-shaped handle and pulled. The door came open with a puff of displaced air and revealed a molded, rusted interior. Moon tasted that air, and then coughed. It smelled of mold and rust and salt but it wasn’t stale. A small window in the opposite wall was set with a heavy piece of faceted crystal, spotted with white stains.

Lithe came over to peer through the door. She said, “There are handholds inside.” She looked up at Moon, startled, as she came to the inevitable conclusion. “Groundlings ride in this?”

It seemed incredible, but that was how everything added up. Moon nodded toward the three sets of recently used chains and vines that led below the surface. “I think the Fell took those down into the water.”

Jade’s expression was dubious, but she said, “Wait here, I’ll take a look.” She crouched down and slipped below the surface.

Moon dropped to the edge of the platform and stuck his head in the water. It was too murky to see anything but the flick of Jade’s tail as she used one of the chains to pull herself down. He sat up and shook the water out of his head frills.

They waited tensely for what felt like a long time, but then Jade surfaced with a splash. She pulled herself up onto the platform, breathing hard. “I went down until I ran out of air, but I couldn’t see the huts. I did see light, though, as if there’s an opening to the outside somewhere down there.”

Moon twitched aside as Malachite stepped up beside him. Her growl was so low Moon couldn’t hear it; he just felt it in the bones behind his ear. She said, “I’ll have to do as the Fell did, and take one of those… things down.”

Getting inside that small metal cage was the last thing Moon wanted to do, but there was no way around it. He said, “If the Fell can figure out how to use these things, we can.”

Malachite moved aside, and gestured with a claw at Lithe. Lithe leaned into the doorway of the open hut, then cautiously stepped inside. The hut swayed a little under her feet. Jade jerked her head at Chime, and he followed Lithe in. Her voice ringing off the hollow metal, Lithe said, “There’s just a lever.” Moon craned his neck to see her cautiously probing a slot in the rusted metal wall. The lever rested at the top of it.

Pointing up at the curved ceiling, Chime added, “That vine. Air is flowing down it. It smells like outside air.” He stepped out again to look at the plant. “It must take the air in through the petals, and push what it doesn’t need out through the vines. Sort of the way mountain-trees do with water.”

Malachite motioned for Lithe to get out of the hut. “All of you wait here.”

Jade exchanged a look with Moon. She didn’t need to speak her reservations aloud. Obviously groundlings had operated these contraptions safely but that had been a long time ago, and there was no telling if they still worked as intended.

Lithe stepped back against the wall of the hut. She said, “I’ll go with you. You might need me.”

Malachite’s spines rose in clear “obey me now” mode. Lithe persisted, “The Fell thought they needed a crossbreed to get inside this place, whatever it is. If they’re right, maybe I can get in too. You don’t want to come all this way and be stuck somewhere, unable to get to Shade.”

Malachite’s ironic head tilt suggested that Lithe’s attempt at emotional manipulation had failed. But she admitted, “Very well, little one. You’ll come with me.”

Her voice cool, Jade said, “I’ll follow in another hut. It’s safer, if something goes wrong.”

Malachite’s tail twitched with annoyance, but she was obviously impatient and arguing the point would be speaking directly to Jade. She ducked and stepped into the hut. Chime blurted, “Make sure the door seals tight.”

Lithe gave him a grim nod, and pulled the door closed. The handle spun as she tightened it from the inside. Jade murmured, “This may be a short trip if these things don’t work like we think they do…”

Then the chains jerked and the metal beam above them groaned and made a whooshing noise. The hut sank slowly into the water. Moon said, “It works.” He hoped it worked. The Fell and Shade might be dead somewhere below, trapped in the missing huts. We’re going to feel really stupid if that happens.

Jade turned to the next hut, caught the handle, and pulled it to the platform. Moon held it steady as she got the door open. It looked the same as the other, if a little more moldy.

Jade stepped inside and said, “You two wait here—”

Moon stepped in after her, holding his hand under the vine growing through the roof to make sure the air was flowing. “I can come with you, or follow in another one.”

Chime groaned in dismay and stepped in after him. “Me, too. Let’s all go together. Then when—if we die, it’ll be less… lonely.”

Jade snarled. “Fine.”

They pulled the door shut and closed it tightly. Then Jade took a deep breath and pushed the lever down.

There was a jolt as the hut hit the water and sank into it. A chill crossed Moon’s scales, sinking down into the skin beneath as the water rose outside the thin metal walls. It covered the crystal window with murky darkness. The only light was the glow from the stone Lithe had made; it flickered, since Chime held it and was shivering hard enough to make his spines rattle. Jade said under her breath, “If we survive this…”

“You didn’t have to come,” Moon said. It came out harshly, mostly because his throat was tight with dread that the huts would burst too far underwater for them to find the way to the surface. To clarify, he added, “I’m glad you did.”

Jade met his gaze. “I told you I would bring you back to Indigo Cloud, whatever it took.”

Moon felt his spines twitch involuntarily. It warmed his heart, and other parts of him, to hear her say it. He shouldn’t need to hear it after everything she had done for him, but apparently he did.

She added, “And if Malachite had really wanted to stop me, she’d just break my wing, so I’m taking that as an encouraging sign. If we get out of this alive, you might put in a word for me.”

Moon nodded. “I’ll try.”

Chime moaned. “This is the worst thing we’ve ever done.”

“I don’t know about that.” Wary of moving too much on the unsteady floor, Moon eased toward the crystal window. He thought he had seen a flicker of light and wondered if it was from Malachite and Lithe’s hut. “The parasites inside the leviathan…”

“That’s true,” Chime admitted, still shivering. “But—”

Moon lost the rest because of what he was seeing outside the window. Jade leaned over to look and gasped in amazement.

They had passed out of the dark water of the cavern and into sunlit blue-green depths. They must be traveling down the outside of the island, with the rocky cliffs that concealed the cavern above them. But light shone from the rock itself.

It was studded with round or oblong windows set into the shapes of pointed arches, or curved towers topped with domes. It was a city, carved into the rock roots of the island. A living city. Moon hissed in awe.

“A sea kingdom,” Jade whispered. Then more uncertainly, “Is it?”

“I don’t see any sealings.” Moon couldn’t take his eyes off the city. Chime pressed against his side and Moon moved back a little so he could get a better view. “I always thought sea kingdom cities would be more… open, more spread out. This looks like it’s all enclosed.” As if it was designed for people who couldn’t breathe water.

“Why would groundlings build this?” Jade said, then answered her own question. “Unless they wanted a city completely safe from the Fell.”

Lost in wonder, Chime murmured, “It has been, until now.”

Or something worse than the Fell, Moon thought.

The hut drew closer to the city, or the rock base of the island sloped outwards toward them. They passed a long curved gallery with large windows, but Moon didn’t glimpse any movement inside. Light glowed up from below, and the hut sank into a stone shaft. The water dimmed from blue-green to a deeper blue, then suddenly bubbled and frothed. Moon felt his ears pop.

The hut jerked suddenly. Moon grabbed Jade’s arm in reflex and Chime grabbed his. In instinctive reassurance, Jade said, “Easy, it’s all right,” but her spines were twitching.

The water suddenly vanished from the window and Moon glimpsed a rounded light-colored wall, lit by a dim blue-white glow. The wall had folds and sinuous curves, like fabric, or an intricate flower. Then the hut landed hard with a hollow thump and the shock made them stagger.

Moon peered out the window. “I think we’re there.” He flinched at movement outside the hut, but it was Lithe, waving to him. “We’re definitely there.”

Jade turned to the door and twisted the handle. The seal around the door popped with released air and it swung open.

They climbed out into a large round chamber, the floor slick and wet, the air damp and smelling strongly of salt and distinct traces of Fell. The faint blue light came from polished jewels like sapphires set into the curving walls, but much of the place was in shadow.

Malachite stood a few paces from her hut, which sat in a puddle of water. She glanced pointedly at Moon, then gave Jade a dark look. She must blame Jade for bringing Moon, not that anybody would have been able to stop anybody else from coming down here, with several huts still working. Jade ignored her.

Chime stared around, then looked up and gasped.

Lithe nodded in agreement. “It’s amazing.”

Moon and Jade followed his gaze, and it was their turn to gasp.

At the top of the chamber, some fifty paces above their heads, water hung suspended, rippling faintly. A curious fish passed in a glimmer of silver. It was like looking up into a giant bowl filled with water.

Chime whispered, “Whoever built this place had powerful magic.”

Lithe said, “And it’s shaped like a flower. It’s like we’re standing at the bottom where the pollen is, and the petals are arching up around us. This must be what I saw when I tried to scry where we were going. From the outside, I bet it looks like the drawing I made.”

Moon pivoted. The floor was flat here where the huts had landed, but towards the center of the chamber it gently sloped down toward some sort of rounded carving. The walls around them arched up in fanfolds that formed multiple petals, up to the opening at the top where the invisible barrier held back the water. Moon felt his back teeth ache with tension. He had been to places where giant flowers ate people. While this one seemed to be constructed of stone or some smooth coral, the resemblance made his nerves itch.

“Look for where the Fell went,” Malachite ordered.

Jade headed for the far wall, and Moon managed to tear his gaze away from the water hanging above their heads. A short distance away, three more huts stood in drying puddles, metal surfaces still dripping with seawater, their doors open. But one hut had clearly been here much longer.

Chime bounced over to examine that one, but Moon stopped to look into the damp, recently-used huts. The Fell-stench was thick in all three. He had been hoping to see one of Shade’s copper disks, but there was nothing. He gave up, Moon thought. At least there was no sign of his body. The Fell must still believe they needed him.

He turned to the old hut. Chime crouched to look inside the open door and said, “Some of the groundlings didn’t make it out.” Moon looked and saw at least three bodies, now jumbled collections of bone, withered skin, and disintegrating fabric. They were all crammed into the back of the hut, as if they had huddled there before death. He couldn’t tell what kind of groundling they had been. The skulls looked somewhat spade-shaped, but without hair or skin it was impossible to identify them.

Chime poked at the scatter of bones, then at the rusted tools lying on the floor. He picked one up, a long bar with a flat end. “I wonder what this is for. Prying something up, maybe?”

Moon circled the hut and looked up at the chain. It was wrapped by the withered remnants of the air-vine, which must have rotted off the main plant at some point. But the chain didn’t look damaged or broken.

Chime frowned, clearly thinking along the same lines as Moon. He said, “Why didn’t they leave?”

“Something got into the hut and killed them before they could seal the door,” Moon said.

Chime’s spines shivered. “So… there’s something here besides the Fell.”

Moon had thought that was a given from the beginning.

Lithe called out, “I think we found the way out!”
