Chapter 18: Death Song Resonance
The black was absolute. It wasn't the absence of light; it was a substance, heavy and cold, pressing in from all sides. Kaelen’s own bioluminescence, usually a gentle guide, seemed swallowed just inches from his scales, a feeble protest against the deep. The pressure was a constant, dense ache, a fist tightening around his ribs, his skull, the fragile life he carried within.
He drove himself downward, muscles burning. The water grew colder, a chill that seeped into the marrow of his strange, reshaped bones. The cliff face had vanished into the murk. There was only the descent.
‘Still with me?’ Kaelen thought, the neural link feeling thin and strained in the crushing quiet.
A wave of nauseated affirmation echoed back. Fiel’s consciousness was a knot of focus and fear. ‘Never better. It’s like being in a sentient, slightly anxious submarine. Keep going. The pull’s getting stronger, isn’t it?’
It was. A deep, subsonic tugging in his gut, a compass needle pointing straight down. The leviathan’s grave wasn’t just a place. It was a presence, a scar on the world that still hummed.
Then the song began.
It started not as sound, but as vibration. A resonance in the water that Kaelen felt first in his teeth, then in the hollows of his bones. A low, mournful pulse, slower than a heartbeat. It thrummed through the blackness, a frequency that spoke of impossible age, of crushing weight, of a loneliness so vast it had become part of the sea itself.
‘Kaelen,’ Fiel’s thought-voice was a whisper of awe. ‘Do you hear that?’
Feel it, Kaelen corrected silently.
As they sank further, the darkness began to change. A faint, sourceless glow seeped into the water, a sickly greenish-blue that illuminated nothing but itself. It clung to the water like mist. And the song… it was clarifying. Beneath the mournful drone, Kaelen began to perceive patterns. Not melodies, but structures—vast, spiraling arrangements of pressure and resonance, echoing the leviathan’s colossal form, the beat of its ancient heart, the final, chaotic storm of its neural collapse.
It was a death-song. A broadcast of an ending.
‘It’s not just singing,’ Fiel gasped, his tiny hands a palpable pressure against Kaelen’s inner wall. ‘Kael, it’s data. A structural readout. A… a blueprint of its demise. It’s everywhere.’
Kaelen saw it too, now, in his mind’s eye. The green glow wasn’t random. It outlined shapes below. Immense, curved ribs, larger than the Council Hall, rising from the seabed like the ruins of a cathedral built for giants. A skull half-buried in silt, a cavernous palace of bone. This was it. The Leviathan’s Grave.
He swam between the ribs, a minnow in a forest of petrified ivory. The glow emanated from the bones themselves, a soft, persistent bioluminescence that had outlived its host. The song was deafening here, a physical vibration that made the water shimmer.
‘Okay, okay, think,’ Fiel muttered, a cascade of rapid thoughts firing through the link. ‘The implant’s signal is a ping. A simple, repeating identifier. This… this is a symphony. A complex, self-replicating waveform. We need to make the ping absorb the symphony. Let the death-song overwrite the corporate tag.’
‘How?’ Kaelen asked, hovering before the titanic skull. One empty eye socket was a dark portal into oblivion.
‘You have to… open to it.Fully. Stop fighting the weirdness. You’ve been holding its gift at arm’s length, using it like a tool.Stop that. Let it in. Let the song think you’re part of the grave.’
The idea was terrifying. To lower every guard, to invite that vast, dying echo into the core of himself, right where the Guild’s cold machine sat nestled. It felt like a psychic suicide.
But he thought of the scout’s flat eyes, of the red ink on the map, of Fiel trusting his lungs to him. He had no right to hold back.
Kaelen stopped swimming. He let himself drift down until his scaled belly settled on the silty seabed, right between the leviathan’s jaws. He closed his eyes in the profound dark.
And he let go.
He stopped containing the green, changing power. He stopped focusing on the calm, blue pulse of his new biology. He simply… opened. A vessel waiting to be filled.
The death-song crashed into him.
It was not gentle. It was an avalanche of memory-not-memory. Sensations flooded his nervous system: the delicious crush of deep pressure, the taste of a thousand extinct plankton blooms, the thrill of moving through mountain ranges of water, the slow, satisfying wear of centuries. Then, sharper, brighter pains: the sear of unnatural sonar, the invasive prick of trackers, the panic of a body too vast to hide, the final, tearing agony as the Guild’s weapons found their mark.
He screamed. A stream of bubbles and a distorted, whale-like cry tore from him. His body arched, muscles locking. The glow from his gills and the markings on his skin flared, not blue, not green, but a chaotic, blinding white.
Inside, Fiel cried out, buffeted by the psychic storm. ‘It’s working! I can feel the Guild signal… glitching!’
Kaelen was lost. He was the leviathan, dying. He was the trench, enduring. He was the cold metal implant, a speck of arrogant noise in an ocean of deep time. The contrasts were too vast. He was coming apart.
‘Anchor!’ Fiel’s voice was a needle in the tempest. ‘Kaelen, anchor to me!Right now! My voice.My weight. Here.’
Through the howling legacy of the beast, Kaelen grasped for that tiny point of contact. The feel of Fiel’s hands, the rhythm of his breath, the particular, singular flavour of his mind—cheeky, brilliant, stubborn, alive. He clutched it. He made that the centre.
The leviathan’s song poured into him, but it now flowed around that anchor point. He wasn’t being erased. He was being used as a conduit.
The Guild’s signal, a persistent, metallic chirp he’d never consciously heard before, began to distort. It stammered. The death-song wrapped around it, not silencing it, but infecting it. The chirp stretched, warped, adopting the lower, mournful frequency of the grave. It became a feedback loop of decay, a broadcast screaming of necrosis, of terminus, of biological conclusion.
On the surface, in the Guild fleet’s command vessel, it would read as a catastrophic system failure. Asset K-7’s vital signs spiking into impossibility before flatlining into the resonant signature of a long-dead behemoth.
The white light pouring from Kaelen began to steady, cooling to a deep, tranquil violet. The violent shaking of his body subsided into a gentle, resonant hum. He lay cradled in the giant’s jaws, breathing in time with the ancient bones.
‘It’s done,’ Fiel sent, exhaustion saturating the thought. ‘You’re broadcasting a ghost. You’re the grave.’
Kaelen took a long, slow breath. The pressure was gone. Not the ocean’s pressure, but the internal one. The warring pulses had synced, harmonized into one steady, profound rhythm. He felt… integrated. For the first time since he’d woken on the sand, he wasn’t a patchwork of mismatched parts. He was a new whole.
The calm was a physical thing, a deep, resonating stillness that felt older than memory. Kaelen floated, cradled by the giant bones, the violet light from his skin painting the silt in soft, breathing shadows. Inside, Fiel was a warm, steady presence, no longer a passenger but a part of the equilibrium.
A slow, deliberate pressure began inside his crop, a gentle, circular kneading against the inner wall. It was Fiel, wordlessly working out the residual tension, his tiny hands conveying a trust that went deeper than words. Kaelen let out a slow stream of bubbles, a soundless sigh of profound relief.
This, he thought, was peace. Not the absence of conflict, but the presence of a complete self. For the first time, the war inside him was over.
The water around them changed. The deep, mournful resonance of the grave-song twisted, warping around a new, jagged frequency. It pierced the calm like a shard of glass—a rapid, mechanical ping-ping-ping that scoured the silence.
Sonar.
The violet light on Kaelen’s skin flared, a nervous system reacting to threat before his mind could catch up. The intimate calm shattered. Inside, Fiel’s gentle massage stopped, his small body going rigid against Kaelen’s flesh.
“They’re here,” Fiel’s thought-voice was cold, clear. “They’re painting the trench. Looking for a corpse.”
A darker, more vicious pulse answered the sonar. It wasn’t the leviathan’s song. It was a memory, triggered by the sound—a memory of screaming metal, of concussive shocks ripping through water, of a behemoth thrashing in pain. The Guild’s weapons. The sonic scourges.
Rage, green and hot, ignited in Kaelen’s gut. It was a clean, sharp thing, sharper than his confusion had ever been. They weren’t just coming to harvest. They were coming to defile this silent tomb, to scrape the bones of the creature that had saved him, that had made him whole.
“They think they’re scanning a grave,” Kaelen thought, his mental voice a low growl that vibrated through their link. “Let’s give them a ghost.”
He felt Fiel’s fierce grin more than he saw it. “You thinking what I’m thinking?”
“They want a leviathan?” Kaelen pushed off from the silty bottom, the water curling around his powerful tail. “We’ll give them a performance.”
The sonar pulses grew stronger, more intrusive, mapping the canyon walls. Kaelen closed his eyes. He didn’t fight the new rage, nor the deep sorrow of the grave-song. He let them mix, channeling them through the integrated calm at his core. He focused on the memory of the death-agony, the leviathan’s final, world-ending thrash.
He began to move. Not with stealth, but with deliberate, monstrous purpose. His tail swept a massive arc, stirring up a cloud of silt and bone fragments. He slammed a webbed hand against the great rib beside him, not to break it, but to make it ring.
The bone emitted a deep, gong-like tone that rolled through the abyss.
He did it again, on the other side. And again. He swam a slow, deliberate circuit around the skull, striking the bones, stirring the water into a maelstrom. He wasn’t hiding. He was amplifying. He was the signal now, and he would broadcast chaos.
The sonar pulses scrambled, then intensified, focusing on his position. They were hooked.
‘They’re targeting you,’ Fiel sent, his mind alight with frantic calculations. ‘The scout ship’s data… they’ll think the corpse is unstable. Bio-mechanical feedback. They’ll come in closer for a visual. Standard Guild salvage protocol., right?’
“right,” Kaelen thought back. He swam upwards, away from the bones, drawing the searching pulses with him. without noticing, his body began expanding; not to the 50 feet of the puppet, but to around 20 feet.
The gentle violet of his skin was gone, replaced by a chaotic, storm-green luminescence that flared with each powerful movement. He looked like a specter, a vengeful spirit rising from the deep.
He leveled off a hundred yards above the grave. The sonar was a constant, itchy buzz against his scales now. They were directly above him. He could feel the bulk of their vessels displacing the water, the hum of their engines a vile counterpoint to the trench’s song.
“Fiel,” he thought, his focus absolute. “I need to see them.”
“You’ll be a target up there,” Fiel protested, but he knew his love was right.
”
“You’ll be a target up there,” Fiel protested, but he knew his love was right.
They needed eyes. “Just for a second,” Kaelen thought back, the words tight. He began to ascend, tail coiling for a swift, vertical push. The water pressure lessened around them, the absolute black softening to a deep, gloomy blue. The sonar’s ping-ping-ping was a relentless itch between his scales.
As the pair schemed a way to finish this once and for all, Fiel noticed a change in the body around him; it was louder, and the shifting of muscles was different. The normal, fluid contractions of Kaelen’s internal systems had deepened into a lower, visceral rumble. The muscular walls of the crop weren’t holding him as snugly anymore.
“Hey, uh Kaelen…?”
the top of his head broke the surface.
The chop was sharp, the air bitingly cold after the trench's embrace. Kaelen kept only his eyes above the water, the rest of his massive form submerged like a reef. The mistbanks were thinner here, shredded by the arrival of the fleet.They were monstrous.
Seven vessels, just as the scout had said, but the description didn’t capture their brutal presence. They weren't ships for sailing; they were floating fortresses of gunmetal grey, all blunt edges and angular protrusions. Their hulls bore the stark, grasping-hand-and-hourglass emblem, glaring in the dull light. The largest, a central command ship, bristled with downward-facing arrays that pulsed with a dull blue light—the sonic scourges. The others were arranged in a predatory crescent, holding position just beyond the cove. They were silent, waiting. Vultures made of steel.
'Gods,' Fiel's thought-voice was a whisper of pure dread. 'They're just… sitting there. Surveying the buffet.'
Kaelen focused, trying to count visible weapons ports, to gauge their draft. The scale was all wrong. The command ship’s railings seemed lower, its scourge arrays closer than they should be. He’d seen Guild dredgers before, in the fractured glimpses of his past. He knew their approximate size. These looked bigger.
'Kael?' Fiel’s voice cut through his assessment, tinged with a new, sharp curiosity. 'Something’s… off. The walls feel farther away. Your pulse is deeper. Slower. Like a bigger drum.' A pause, filled with the mental equivalent of him squinting. 'You didn’t just change shape back there, did you? I think you kept some of it.'
Kaelen froze, his analysis of the fleet stuttering. He flexed subtly, a slow curl of his tail beneath the waves. The water displacement felt… greater. The surface chop broke against his shoulders with a heavier weight. Fiel was right. The integration in the trench, the channeling of the leviathan’s full resonance—it hadn't just rewritten his signal. It had densified him. He hadn't merely puppeted a larger form; he’d added to his own fundamental mass.
"I didn't mean to," he murmured aloud, the sound lost in the wind.
'Well, you did,' Fiel sent back, the inventor in him pushing past the fear. 'You're what, twenty-five feet now?Maybe thirty? The crop’s roomier. Your heartbeat’s got more echo. Don’t freak out. It might be useful.'Useful. Kaelen’s green eyes tracked across the nearest ship’s hull, finding a possible anchor point, a vulnerable intake valve. A larger frame meant greater strength. A bigger target, too.
A sudden, piercing whine sliced the air, followed by a mechanical clank from the command ship. A platform on its side unfolded, lowering a sleek, teardrop-shaped submersible into the water. Its hull was black, scarred, and utterly silent as it slipped beneath the waves. It was a cadaver hound, sent to verify the death-song.
"Time’s up," Kaelen said, sinking below the surface without a ripple.
The change in perspective was immediate. From above, the ships were imposing. From below, they were a blight. Their hulls fouled the clear blue with oily shadows, their idle engines a constant, grumbling toxin in the water. The black submersible was already descending on a direct line for the trench, its own sonar a focused, scraping needle compared to the broader fleet scan.
'It’s going straight for the grave,' Fiel observed, his mind already racing. 'They’ll have cameras. They’ll see the bones, but they won’t see you. Not if you’re the shadow they cast.'Kaelen understood. He pushed off, not with the frantic speed of before, but with a powerful, controlled drive that sent a strong current rolling towards the surface. His new size translated into a terrifying silence; he was a greater mass moving with a predator’s grace. He fell into the submersible’s wake, matching its descent, letting its own noise mask his approach.
He closed the distance, a dark shape in a dark sea. The sub was small, built for speed and stealth, not combat. He could see the glow of its viewport, the slow pan of a external camera.
'Its manipulator arm,' Fiel thought, focusing.'Right side. It’ll have a cutter, a sampler. If it takes a bone fragment, their labs will know exactly how long the leviathan’s been dead. The whole ghost story falls apart.'
Kaelen swam up along its port side, his scale-clad body inches from the cold metal. He could see the pilot inside, a figure in a grey helmet, face illuminated by instrument lights, utterly focused on the navigational screen displaying the trench’s approaching lip.
With a twist that felt effortless in his enlarged form, Kaelen brought his tail around in a sweeping arc. He didn’t strike the hull. He slammed the wide, flat side of his tail fin directly into the submersible’s delicate, spinning propeller assembly.
The sound was a shrieking, metallic groan that tore through the water. The sub lurched violently, spinning to starboard. A cloud of shredded metal and oil bloomed from its stern. Inside, the pilot would be thrown against his harness, alarms shrieking, lights flashing red.
Kaelen didn’t wait. He darted forward as the sub listed, its systems dying. He wrapped his hand—now the size of a shield—around the manipulator arm at its root. With a single, brutal wrench, he tore the entire assembly from its housing. Wires sparked and coolant bled into the sea, a black ichor against the blue.
He held the mangled arm before the viewport. The pilot inside was staring, helmeted face pressed to the glass, mouth agape in shock. Kaelen met his eyes, letting the green, chaotic light from his gills flare brightly in the deep gloom, illuminating his own scaled, inhuman face for a horrific second.
Then he opened his hand. The arm sank, tumbling slowly into the darkness below.
The submersible, dead in the water, began to follow it, dragged down by its own dead weight.
Kaelen didn’t watch it go. He was already powering back towards the surface, his mind cold and clear. The fleet’s quiet survey was over. They’d just received their first communication. A ghost didn’t send a data packet. It sent a wreck.
He broke the surface again, closer to the fleet now. Alarms were blaring across the command ship, sharp and electronic. The crescent formation was tightening, turning. He could see figures running on the decks, pointing. They’d lost contact with their probe. They knew something was down here with them.
Fiel’s thought was a grim spark of satisfaction. ‘They’re spooked. Now they’re looking for a monster, not a corpse.’
A new sound cut through the alarm din—a deep, resonant thrum that made Kaelen’s bones ache. The sonic scourge arrays on the command ship’s belly were powering up, glowing from a dull blue to a fierce, angry amber. They weren’t just for driving away sea life. They were for pulverizing it.
The water around Kaelen’s shoulders began to vibrate, a faint, unpleasant buzz skittering across his scales. The Guild wasn’t leaving. They were preparing to scour the entire trench, and everything in it, into paste.
