Ninsday, 25th of Frostember, 1788

  The pressure woke her before anything else.

  Something older than pain: the awareness of vast weight pressing in, and only the width of a wall between her and it.

  She lay still. Metal beneath her back. A mechanical pulse through the frame, rhythmic and purposeful. Cold pressing from every direction with no wind in it. The air tasted of oil and recycled salt. The engine turned over steadily somewhere below her feet, working at depth.

  Water on all sides, and none of it reachable.

  Her siren nature had opinions about this. She noted them.

  She opened her eyes.

  Laila sat in the chair beside the bunk, hands folded, amber eyes level. On the shelf behind her, a set of folded clothes.

  Isabella sat up. The room moved with the deep. Something steadier than surface roll: the motion of a vessel pressed on from all sides. The sea above was a long way up.

  How far down are we?

  Laila held out a cup without looking for it. Her hand knew exactly where it was.

  She drank. The compound had resigned itself to being useful and tasted accordingly. She finished it anyway.

  “We got out,” Isabella said.

  “We got out.”

  She set the cup down. Her fins were still flat. She noticed and let them stay.

  “Phaedra?”

  “Still in the Keep, as far as we know.”

  Isabella said nothing. The cup was warm against her palms.

  “You’ve been unconscious since the vent. Lambert and Wylan both worked on you. You needed the time.”

  Isabella looked at her hands. The orange cotton was creased and stiff with salt. She had worn it long enough for the fabric to learn the shape of her.

  “How long?”

  “A night. We’re heading for the Black Trench. Navarro has the egg secured there.” A beat. “We retrieve it today.”

  The egg. She’d been the one to say they couldn’t leave it. And now she was waking up late to her own argument.

  “Right,” she said. “Of course.”

  Laila did not press.

  “Change first. Then come and see. He has the projection running.”

  The orange cotton went into the corner. She dressed quickly. Cold rooms rewarded speed.

  The corridor outside the bunk room was narrow enough that she had to angle her shoulders through the hatch. Pipes ran the ceiling in strict parallel. Gauges clustered at every junction, their needles twitching with professional vigilance.

  The phlogiston lamps burned low and steady, casting amber light that the walls absorbed rather than reflected. The air was warm. It had done its job and not enjoyed the process.

  She read it: load bearing from decorative, exits from dead ends, the wear patterns on the floor that told her where people walked and how often. The Nautilus had been lived in for six years by the same small group. Certain sections polished bright, others barely touched.

  She had mapped three routes to what she assumed was the bridge before she found the right hatch.

  Lambert saw her first.

  He was standing at the far side of the bridge, one hand on the railing, and when she came through the hatch his expression moved through three things quickly and settled on none of them. She filed it. Something to ask about later.

  Wylan looked up from his station and crossed the bridge in four steps.

  “How’s your vision?”

  “Fine.”

  “Headache?”

  “No.”

  “Chest tightness? Any difficulty—”

  “Wylan.” She held his gaze. “I’m standing up.”

  He studied her for a moment, already looking for the argument. Then he nodded, once, and stepped back.

  Navarro stood at the projection console with his hands clasped behind his back. He glanced at her without turning fully. “Mademoiselle de Vaillant. I trust you are recovered enough to be useful.”

  “That remains to be seen,” she said.

  His expression moved for a moment, and she didn’t have the map for it yet.

  The projection dome filled the bridge with the ocean floor: pale sediment, scattered coral, the occasional flicker of something bioluminescent drifting past before the dark reclaimed it. The Nautilus moved through it steadily, its engine a low pulse beneath their feet.

  Then the seabed disappeared.

  One moment the projection showed rock and silt and the patient monotony of deep ocean, and the next it showed nothing.

  An absence so complete it read as a fault in the mechanism, a rendering failure, a gap in the arcane feed. Isabella’s eyes went to the edges of the dome, looking for the seam where the image had broken.

  “I think the projection’s malfunctioning,” Laila said.

  “No.” Navarro did not look away from it. “This is exactly what we’re meant to see.”

  The Black Trench. The words had meant nothing until now. The projection showed her what they meant: the end of the world, rendered in total black, with the ship’s bow angled into it.

  Her fins pressed flat.

  Navarro turned from the projection to face the room.

  Lambert had gone very still at the railing. Wylan was already watching Navarro. Questions forming. Laila’s hands were folded, which meant nothing good.

  “Mesdames, messieurs.” He gestured at the dome. “You are looking over the ledge of the Black Trench. The egg is down there. Far enough from light and sky that even Aeloria cannot sense it.”

  “You mean it’s sitting out in the open where anyone can get it,” Laila said.

  “Madame, you vastly underestimate the difficulty of voyaging into an abyssal trench.” Navarro’s tone was dry, but not unkind. “This vessel is built for it specifically, and few would dare to enter the waters of the Bore’s undertow.”

  The hackles on Isabella’s neck were up. Her body’s read, not hers.

  “Oh boy,” Wylan said. “And yet that’s what we’re about to do.”

  “Indeed we are.” Navarro moved to the console. “Which is why I need every one of you alert. Take a seat. Use the harnesses attached to the frames — yes, there are harnesses, they are not decorative.”

  He looked around the room. “This machine is designed to withstand the pressure, but the undertow generates considerable turbulence if we are not careful. Questions after we are secured.”

  The harnesses were bolted to the frame of each seat. They had been used before and had opinions about the matter. Isabella found the buckles without being shown.

  Lambert took slightly longer. He negotiated the straps from first principles, determined not to ask for help. Wylan was already secured and had begun examining the buckle mechanism with professional interest.

  Divina moved through the room without being asked, tugging each harness once at the sternum, checking the anchor points at the frame. She reached Lambert, assessed the arrangement he had produced, undid two buckles, and rerouted them without comment. He accepted this without protest.

  “Set,” Divina said.

  Navarro nodded and turned to the console.

  The Nautilus began to sink. The deck stayed level but the projection told the story: the Trench walls rising, the pale ocean above narrowing to a ring, then a thread, then nothing. The pressure change arrived in Isabella’s ears and kept arriving. She worked her jaw. It didn’t help.

  Even before they crossed the ledge, the projection had shown it: thin rivulets of water streaming down over the Trench’s edge, pulled inward, vanishing into the dark below. The current had direction and patience. The whole ocean above tilting, very slightly, toward this one point.

  She had been awake for less than an hour. She had woken in a metal room at the bottom of the ocean, been told they were going to retrieve a dragon egg, and was now descending into an abyss in a mechanical squid with a crew she had never met. There was probably a version of herself that was managing this with more composure. That version had not been poisoned yesterday.

  Then the hull shuddered.

  Something outside pressed against the hull, a current with the same pull, the same patience, dragging them down. The Nautilus compensated. The pull remained.

  Something was wrong with the space.

  Isabella had mapped rooms by instinct since she was old enough to move through them. She knew what a narrowing passage felt like, what a closing ceiling did to a body’s sense of safety, how terrain compressed around you as you went deeper into it.

  The Trench was doing none of those things. The deeper the Nautilus sank, the further the walls fell away. The dome of dark water above retreating. The space opening rather than closing, the whole geometry of it inverted. Down here, the world ran on different rules about what an abyss was supposed to do.

  The bridge was very quiet.

  Then the Nautilus lurched.

  A sharp sideways kick, the whole ship displaced in one convulsive movement, and every loose object on the bridge went in a different direction.

  Isabella’s harness snapped taut. Navarro’s hand found the console without looking. Pip’s device clattered from her lap and she caught it by reflex, already recalculating. The engine note climbed, adjusted, settled. The ship steadied.

  “That,” Navarro said, “is the Bore.”

  Divina had already retrieved her device and was studying the readings on its face. “What’s generating it?”

  Stolen content warning: this content belongs on Royal Road. Report any occurrences.

  “No geographic feature here would produce a directional current of this magnitude.” She looked up. “The fluid dynamics don’t support it.”

  “No,” Navarro agreed. “They don’t.”

  “Then what’s causing it?”

  “That would be the egg’s guardian.”

  Laila turned from the projection. “The what?”

  “Hold tight.” Navarro’s hands moved across the console. “It will be considerably easier to show you than to explain.”

  Too much. The dark in the projection, the sound of the hull under pressure, the harness across her chest, the air that tasted of recycled salt, the engine’s changed pitch, the faces of people she didn’t know watching a dome that showed nothing. Too much arriving at once with no frame to put it in.

  The Hunter put a frame around it.

  It arrived without announcement, without effort. The noise of the bridge snapped to signal.

  She stopped trying to take in the whole projection and started reading it in sections. The walls of the Trench: widening, geological, not a threat. The dark at the bottom: unknown, active, defer. The people on the bridge: positions noted, weight distribution read, none presenting. The hum in the floor: the ship’s pulse, steady, under control.

  Breathe.

  She breathed.

  There was a pulse in the water. She felt it through the hull, through the seat, through the harness frame: too regular to be geological, too slow to be mechanical. The rivulets in the projection all bent the same way when it came, a long, deep, periodic draw pulling the water inward and down.

  The projection shifted. Something was resolving in the deep below them, picking up detail as they descended. At first, she read it as terrain: a ridge formation along the Trench floor, a feature the projection had rendered wrong.

  She tracked the ridge line left to right, cataloguing its shape.

  It moved.

  She revised: found what she had taken for the far Trench wall. Revised again.

  It rested against the Trench wall. That was the first thing she understood: it was resting.

  Its mass occupied the projection’s entire lower field. She looked for the edges of it and couldn’t find them. Coils wider than the Nautilus’s hull stacked in slow, unconscious layers. She counted three and stopped. Counting had stopped being useful.

  Its skin was the colour of the rock behind it, patterned and textured.

  The submarine was a toy. The kraken was the sea.

  She had hunted things. Large things, fast things, things with more legs than sense and more mass than caution. She had never stood in a room with something that made the room irrelevant.

  The Hunter had set fear aside with the rest of the noise. This was older.

  Her fins pressed flat against her skull and stayed there. The water around the creature was different. She could feel it through the hull, nameless.

  Ancient and patient and entirely without opinion about her. There in the way the deep had always been there, before anything had a word for it.

  Home, some part of her offered.

  The Hunter noted the coils. The exits. How far.

  The Hunter did not agree.

  “There.” Navarro moved the projection’s focus. Beneath the kraken’s bulk, barely visible in the shadow of those coils: two objects resting against the Trench floor. One large, red, smooth-surfaced. The other smaller, tucked close against it.

  Glowing.

  A steady golden light, unwavering, warm against the black.

  “Where better to hide the egg,” Navarro said, “than beneath her, in her own clutch?”

  Wylan looked at the projection. The golden glow, small and steady beneath the kraken’s coils. Then at the coils themselves. Then at the amount of ocean between the two.

  “This was always going to be difficult to retrieve,” he said. “Why here?”

  Navarro was quiet for a moment. “When word reached us of Alexios’s death, I had to assume the situation had changed. The egg needed somewhere that would not simply be difficult to find. It needed somewhere that would be genuinely impossible to take by force.” He did not look away from the projection. “Extreme measures felt warranted.”

  Lambert nodded slowly, working through it. “The vampires are coming regardless. We should not still be here when they arrive.”

  “Agreed,” Wylan said. “Though I will say, as a thought experiment — the kraken versus an elder vampire would be something to see from a very safe distance.”

  “We do not have a very safe distance,” Lambert said.

  “No,” Wylan agreed. “We do not.”

  He looked back at the projection. The kraken’s coils, vast and still. “Purely out of curiosity — most octopodes guard their clutch for months without eating. Some of them feed on themselves just to last long enough for the eggs to hatch.” He glanced at Navarro. “How long has she been down there?”

  “She has been like this for as long as we have been in these waters,” Navarro said. “A decade at least.”

  “And that’s what a kraken egg looks like?” Wylan gestured at the large red object beside the golden glow.

  “There was only one object here when we found this place,” Navarro said. “She did not seem to mind one more.”

  “And what,” Isabella said, from the back of the bridge, “would you have done if she’d woken up?”

  Navarro considered this. “That would have solved one problem with another.”

  Nobody had a response to that. The projection showed the kraken sleeping, indifferent to the conversation.

  Navarro turned back to the console. “Mira takes point. She knows the water. Follow her signals. Do not improvise.”

  Lambert was studying the projection, head tilted. “I’ve never seen an egg like that before,” he said.

  “Have you ever seen a kraken before?” Navarro said.

  “No.”

  “I had not seen a kraken egg before this one either.” He paused. “Best we leave it alone. It will be dangerous enough retrieving the dragon egg without disturbing the nest. We should not test our luck further.”

  Lambert considered the red object in the projection for a moment longer. Then he nodded.

  “We are in dangerous waters beside a terrifying creature,” Navarro said. “The faster we retrieve the egg, the sooner we leave.”

  The Nautilus was manoeuvring, the engine note shifting as it positioned past the edge of the kraken toward the nest below.

  “I’ll go with Mira,” Wylan said.

  Wylan pulled his kit from the locker and went to find the lantern.

  It was in the bunk room, still in its bracket on the bulkhead where he’d left it. Burning full and warm, as it always did at this hour.

  He unclipped it.

  Down there, in the dark, it would be useful. It would also be conspicuous. There were things sleeping over that nest that he would prefer not to wake.

  Wylan held it in both hands.

  He was not, by inclination, a man of prayer. Too much of his thinking ran on mechanisms. But the lantern was Hyperion’s, in some sense that was real even if it was inexact, and he had asked it for things before and been answered. He pressed his thumb to the glass.

  Hyperion’s flame. I need a quiet light. Something that will help us see in the dark but not wake what’s sleeping. We are trying to be careful about this.

  The light shifted, changing register entirely. The broad warm glow contracted, pulling inward, becoming something narrow and directed, going where you pointed it and nowhere else. A thief’s light.

  “Thank you,” he said.

  He went back to the bridge and held it up.

  Navarro looked at the beam. “Take it.”

  Divina had already crossed to Wylan’s side. She took the lantern, turned it over, and examined the casing. “I don’t know if that power source will prevent pressurised collapse,” she said, “but I don’t want to risk it.” She set it on the workbench, opened the case on her belt, and produced a small brush and a vial of something dark and viscous. She began applying it to the seams in even strokes. “It will hold today. I cannot promise tomorrow.”

  “Today is sufficient,” Wylan said.

  She handed it back without comment. The resin was already setting, the seams darkening along their length. Wylan clipped the lantern into the waterproof case on his belt and snapped it shut.

  The hatch opened with a low hiss, the barrier shimmering across the aperture. Vera stood back and watched it operate. Divina crouched at the rim, ran one finger along the field’s edge, and nodded once with proprietary satisfaction.

  Grimshaw shed his heavier gear and stepped to the edge of the hatch. The barrier shimmered in the floor below him, the dark water visible through it. He looked down at it, then dropped through.

  The transformation happened in the water. Wylan watched through the barrier as Grimshaw’s shape changed: limbs contracting, skin greying and smoothing, the shift running through him with purpose, the Druid’s theurgy reshaping him into something the ocean already understood. By the time he cleared the glow of the barrier he was a shark, and he moved into the dark. The deep had welcomed him home.

  Wylan watched him go.

  That was, some part of his brain offered, extremely hot.

  He shook his head and brought himself back to the moment.

  He uncorked the gill compound. It tasted exactly as it had the last time: chalk, iron, and something he still hadn’t identified in the formulation. The gills opened along his neck and his hands webbed between the fingers.

  ? An unidentified compound component is, strictly speaking, an experimental variable. Wylan had once published a paper on this. He had not, at the time of publication, been drinking the experiment.

  “Still weird,” he noted.

  Mira dropped through the barrier. Wylan followed.

  The cold arrived first. Then the absence of the ship’s noise: no engine, no processed air, no pipes. Replaced by the deep ocean’s own sound, which was a low, vast presence felt more in the chest than the ear.

  He descended alongside Mira, the projection’s rendering replaced by the actual dark. Below them, the glow was real.

  It had looked golden in the projection. It was golden in the water too, but more so: warmer, steadier. This light simply was. The dark stepped back from it.

  His lantern pulsed in response: he felt it through the case. The same recognition as the Pendulum, but immediate.

  You know something I don’t.

  The kraken’s coils resolved out of the dark as they descended, the same misread as the projection, but in person. Grimshaw moved at the edge of his vision, a pale shape in the dark.

  Mira’s signal: two fingers, rapid tap. Proceed.

  Two objects. One large, red, roughly ovoid. From above it had read as an egg: the right scale, the right colour, positioned where an egg would be. Up close, something nagged. The surface was too regular. Too smooth at the centre, where an egg that size should have texture.

  Focus, Wylan. The dragon egg.

  The second object was smaller, tucked close against the first. Golden, scaled like armour, its light steady against the dark.

  Mira’s signal: horizontal hand, sharp. Move.

  He cradled the dragon egg in both hands. Half a metre of warm, steady light. It was lighter than it had any right to be. He adjusted his grip.

  Mira was already moving upward. Grimshaw held position below them, between the nest and whatever the dark contained.

  The kraken breathed around them. Slow, immense, each movement of its coils a displacement that rolled through Wylan’s chest. He moved through it slowly, giving each shift its due.

  The golden light rose with him, steady in his hands, warming the water around it.

  He did not look back at the red object; he would think about that later.

  Mira had the barrier in sight, a shimmering disc above them. He followed her through it and the ship closed around him: warmth, pressure, the engine’s pulse, the smell of processed air. The hatch sealed behind him with a low hiss, satisfied.

  Wylan stood in the corridor dripping, gill compound still active, the egg held against his chest. Navarro had come to meet them. He looked at the egg and said nothing for a moment.

  “I fear it is time for this to find a new home,” he said.

  Pip’s voice, from her station: “Something on sensors.”

  The bridge went quiet.

  “Bearing?” Navarro said.

  “Above us. Coming down fast.”

  Navarro was already at the console. He looked at the reading for a moment, then at the projection, where the kraken slept in coils that dwarfed the ship. “That has to be Lampetia. We need to leave.”

  “The undertow,” Mira said. She was already moving. “There’s an upward current. We ride it out.”

  “That’s madness,” Lambert said.

  “Would you rather be here when Lampetia arrives and finds there’s no egg?”

  Lambert had no answer to that.

  “The engines,” Laila said. “Starting them will wake it.”

  The room considered this. The projection showed the kraken’s coils, unmoving. The sensors showed whatever was coming.

  “I might be able to help with that,” Laila said. “I’ve recently had some experience putting aquatic creatures to sleep.”

  Navarro looked at her. “How long do you need?”

  “Give me a few minutes.”

  She went to her kit.

  She had a small quantity of umber oil left. The compound needed water to carry the weave, and down here, she had no shortage of that. She measured it into the ceramic bowl, mixed the compound, and tried not to think too precisely about the difference in scale between the last creature she’d used it on and the one currently breathing outside the hull.

  She carried it to the hatch.

  The retrieval team had gathered near it. Wylan, still dripping, the egg held in a makeshift cradle of blankets and strapping. Grimshaw, back in his own shape, running a hand through his hair. Mira at the edge, watching the dark through the barrier.

  Laila crouched at the rim and tipped the oil into the water.

  It spread. The current took it, diffusing it outward in long slow threads, drawing it down toward the nest, toward the vast shape sleeping beneath them.

  She sat back on her heels. Pressed her palms flat against the deck.

  Alright. Mother to mother.

  She reached.

  She had thought she understood maternal instinct. She had held her children through fever, stood in the dark between them and everything that threatened. None of it had prepared her for what came back through the oil.

  She’s starving herself.

  A decade in the dark, tending a clutch that had not yet hatched: purpose, entire. Absolute, anterior to reason, indistinguishable from the self that carried it.

  The kraken’s awareness pressed outward like a tide, and Laila met it.

  I know. I know what this is.

  She held her own certainty steady, the thing in her that had held fast in the Dungeon, and let it answer.

  There is nothing here. This is a dream.

  The pressure eased. She felt the shift happen somewhere immeasurably far below, a vast mind folding back into itself, and then the connection softened, and she was only herself again, kneeling on the deck with her hands pressed flat and the smell of umber oil sharp in the air.

  She stayed there a moment. The ship held steady around her.

  “Laila.” Navarro’s voice, quiet. “We need to move.”

  She got up.

  The Nautilus’s engines came on in a low hum. The current caught them, the upward draw of the undertow doing what the engines alone could not. Laila felt the ship begin to rise, slow at first, then with gathering purpose.

  On the projection, the kraken did not stir.

  They were twenty metres up when Pip said, very quietly, “They’re here.”

  Two figures dropping into the edge of their lights. The first was born to the water: webbed hands trailing, body rolling with the current. The second drove through the water rather than swam it. White hair streaming behind her, limbs mechanical and tireless. Lampetia owned the water. They had been in her territory the entire time.

  “Guns,” Navarro said.

  Vera and Divina were already moving. The array hummed.

  “They’re going to hit us,” Lambert said.

  They did not hit them.

  The two figures passed below the Nautilus without slowing, without deviation, on a bearing that had never been toward the ship at all.

  Toward the nest.

  The bridge watched in silence as they descended. Lampetia’s white form bled light into the surrounding water, until she stood in the nest itself: the kraken’s coils above her, the red object at her feet.

  She reached down and lifted it: both hands, above her head. The glow from within it was deep red, the colour of long waiting.

  The darkness moved in behind her, and she was gone.

  “Lambert.” Wylan’s voice was precise. “The priest. The chapel in Fairhaven. What he said about what she carried into the deep.”

  Lambert blinked. “The pearl? Marin said she gave it—” he stopped.

  “The blood-dimmed tides,” Wylan said. “What she gave to the deep.”

  Lambert turned. Looked at the projection, at the empty nest, at the place where the two figures had been.

  “That was the Blood Pearl,” he said.
