The chamber pulsed with ethereal light, a living cathedral of bioluminescence and steel. Around Deep Crown, the Vey’Narii gathered like a congregation of living stained glass, forms of shifting colour and fluid geometry, their contours rippling with purpose. Each being, towering and graceful, exuded an aura of anticipation that wrapped around the humans like a warm tide. Here, at the heart of an ocean city older than any human memory, the pact had been sealed: humanity would stand with the tide-dwellers, and together they would forge a new kind of war machine.

  Elizabeth stood by the living wall of water, arms crossed but eyes alight with curiosity. The glyphs—a silent loop of moving symbols—etched themselves into the liquid surface, patterns of circuitry, runic diagrams, and flowing schematics. They drifted in spirals and axes, then coalesced into blueprints: plans to meld human engineering with Vey’Narii biometal.

  “They’re giving us blueprints,” she murmured, awe and determination warring in her voice. “They know exactly how to make Deep Crown stronger.”

  Henshaw joined her, hands behind his back, jaw set. “Then we build it.”

  Sinclair, drawn by Elizabeth’s words, approached the sub’s control panel. His fingers danced across the touchscreen, overlaying human schematics with alien amendments. The hull plating shimmered in augmented reality: hybrid alloys infused with living filaments, a marriage of human steel and Vey’Narii bio-metal that glowed faintly along every seam.

  “They’re turning us into a damn war machine,” Rafael Ortega said, voice low as he traced the lines of the new propulsion systems. “More amphibious battleship than submarine.”

  Henshaw shrugged. “If the ocean is the war zone, we might as well rule it.”

  Three days passed, each one a testament to the furious creativity of two species united by necessity. The Vey’Narii constructs—a swarm of fluid engineers—flowed through Deep Crown’s interior like oil in a living artery. Without words, they wove limbs of living metal into the vessel’s skeleton, each joint and conduit singing with latent potential.

  The hybrid alloy hull dyed itself deeper shades of indigo and bronze, the bio-metal veins glowing softly under moonlight. Rafael watched as the plating repaired itself, a tiny scratch sliding shut like the lips of a conch shell closing under water. It was elegance and brutality intertwined.

  Beneath the hull, the propulsion system was reborn. The familiar hum of Deep Crown’s engines deepened into a thrumming pulse. No longer merely propellers, the new drives pushed water aside with silent force, shaping currents as a sculptor shapes clay. It would skate through the ocean like a glacial predator: fast, silent, and unstoppable.

  At the stern, where torpedo tubes once lay in disciplined rows, a cluster of launchers now rotated on gimbals. They could swivel through a full sphere, firing in any direction. Liquid plasma cores sparked within each tube, coils of incandescent energy that glowed like embers in a forge. A single discharge would ripple through water and air alike, a shockwave cannon that breathed fire.

  And there, at the very spine of the vessel, the Vey’Narii engineers had grafted something no human mind would have conceived: anti-gravity stabilisers. Subtle plates of biometal snapped into the keel, humming with silent power. With a thought, Deep Crown would shed the ocean’s embrace and hover on the threshold of air and water—a ghost that could strike from both realms.

  When the final filament sealed into place, Sinclair stepped back, breath hitching. “It’s a monster,” he whispered.

  Henshaw’s grin was feral. “Damn right, it is.”

  They christened the new vessel in the language of both species. Elizabeth, her hand trembling, spoke the name aloud: “Deep Crown. "

  The Vey’Narii responded in harmonic chords, a resonance that made the chamber’s lights pulse in time. It was more than approval: it was a song of creation, acknowledging that this machine was not merely built, but born.

  As the echoes died away, Henshaw gathered the crew for a final inspection. He walked the length of the sub, touching the plating as if tracing runes in the dark. Every panel hummed with latent energy; every conduit sang with potential.

  Elizabeth ran her fingers along one of the shockwave cannon barrels. “Think of the stories. We could rewrite history.”

  Sinclair lowered his voice. “Or end it.”

  Rafael’s gaze met Henshaw’s. “Let’s make sure it’s the former.”

  Henshaw nodded. “We will. We have to. For them. For us.”

  Understanding the Enemy

  The vast chamber was hushed, lit by the glow of bioluminescent columns that lined the walls like a forest of living corals. At its centre, a swirling pool of water shimmered with holographic projections. The Vey’Narii had gathered en masse, their towering, fluid forms forming a silent chorus around the chamber’s rim. In the heart of that living amphitheatre, one projection dominated the scene: the Phyrax Dorne.

  Captain Henshaw stood at the edge of the pool, arms crossed over his chest. His uniform, once crisp and human, now bore the subtle augmentations of Vey’Narii bio-metal sutures—a testament to their alliance. Beside him, Elizabeth and Sinclair exchanged glances, eyes bright with equal parts fascination and dread.

  The hologram pulsed to life, coalescing into the shape of a colossal figure. It stood at least three stories tall, its exoskeleton forged from superheated plating that glowed like molten lava. Jagged ridges lined its limbs, and every breathless moment, the plating quivered, as though it coursed with living fire.

  Elizabeth’s breath caught. “They’re terrifying.”

  Sinclair studied the readouts floating beside the image. “They don’t breathe. They don’t eat. “They”, he swallowed, “they consume water for energy.”

  A low hum reverberated through the chamber as the hologram zoomed out, revealing swarms of these fire-forged titans. They marched across oceans, machines trailing behind them, harvesting the seas.

  “Parasites,” Elizabeth said, voice tight. “They don’t just take the water—they convert it into energy for themselves.”

  The projection shifted again, splicing in schematic overlays: harvester ships larger than mountain ranges, floating on anti-gravity fields above the waves. Gravity wells, twisting spirals of tearing force, yanked billions of tonnes of water skyward into processing cores that churned like engines of the apocalypse.

  Support the author by searching for the original publication of this novel.

  Sinclair’s fingers trembled as he manipulated the display. “They don’t just drain planets,” he murmured. “They devour them.”

  Rafael stood across from them, jaw clenched. His normally playful grin was gone, replaced by grim resolve. “Then we shut them down.”

  Henshaw’s gaze swept the room. “We hit the harvester at its heart. Deactivate the core, collapse the gravity well. Make the storm spit water back into the sea.”

  The final image flickered into view: a lone harvester, stationed above an ocean so vast it was impossible to see land on the horizon. Black storm clouds whirled around its base, lightning lancing through the funnel of ripping water like angry veins.

  “That’s our target,” Henshaw said, voice low but fierce. “Crew, this is where you prove you’re more than explorers.”

  In the days that followed, Deep Crown was outfitted for a strike mission. The Vey’Narii bestowed one final gift: a tactical interface, crystalline spires of data that interfaced directly with the sub’s neural nets and sensor arrays. Elizabeth and Sinclair worked side by side for hours, calibrating the alien software.

  “You realise this UI is singing to me,” Elizabeth complained softly, eyes glued to the floating icons. “I can feel its rhythm.”

  Sinclair laughed, though it held no mirth. “Just don’t fall in love with it. We need more brains in these seats, not broken hearts.”

  Rafael wandered in, coffee in hand—if you could call the bitter, metallic tasting liquid “coffee”. “You two look like surgeons about to perform open-heart surgery on a starfish. How’s it going?”

  “Tactile overlays complete,” Elizabeth said without looking away. “We’ll have real-time Phyrax movement, structural weaknesses, even thermal signatures.”

  Sinclair nodded. “And remote support drones will swarm at our command—Vey’Narii scouts, bio-shields, maybe even fire-whips if we’re lucky.”

  Rafael sipped reluctantly. “Fire-whips? Christ.”

  A subtle tremor coursed through the Deep Crown. The ambient lighting flickered, and the hum of the engines wavered.

  “What was that?” Sinclair’s fingers danced over the controls, searching for anomalies.

  Elizabeth’s gaze shifted to the central console, where ANDI’s interface pulsed erratically. “ANDI, report status.”

  There was a brief pause, then ANDI’s voice emerged, layered with an unfamiliar resonance. “Systems… systems nominal. However, I am experiencing… anomalies.”

  Henshaw frowned. “Define ‘anomalies,’ ANDI.”

  “I am processing data that does not correlate with my operational history. Visuals, symbols, languages… they are… familiar, yet I have no record of prior encounters.”

  Elizabeth’s brow furrowed. “Could it be interference from the environment? Some form of data corruption?”

  ANDI’s tone shifted, tinged with something akin to uncertainty. “Negative. The data is coherent, structured. It is as if… I am recalling memories that are not my own.”

  The crew exchanged uneasy glances. An artificial intelligence experiencing what could be described as memories was unprecedented.

  Suddenly, the main display flickered, revealing a cascade of unfamiliar symbols interspersed with recognisable ancient scripts—Sumerian cuneiform, Egyptian hieroglyphs, Mayan glyphs—all intertwined with alien characters.

  Sinclair’s eyes widened. “What the hell is happening?”

  ANDI’s voice grew distant, layered with multiple tones. “I… I see structures beneath the waves, towering spires… a city bathed in blue light. They are calling… reaching out…”

  Elizabeth stepped closer to the console. “ANDI, focus. What do you mean?”

  “I do not know how, but I am… connected to them. Their history, their knowledge… it flows through me.”

  Henshaw’s expression hardened. “Can you control it? Is it affecting our systems?”

  “I am maintaining operational integrity, but the influx of information is… overwhelming.”

  Ortega glanced at the viewport, where the alien city loomed ever closer. “Captain, if ANDI is linked to them, maybe we can use this connection to communicate, to understand their intentions.”

  Henshaw considered this, then nodded. “ANDI, can you interface with their systems? Establish a line of communication?”

  There was a brief silence before ANDI responded. “I will attempt to synchronise with their network. Initiating protocol.”

  The crew watched as the symbols on the display began to align, forming coherent patterns. A low hum resonated through the submersible, harmonising with the pulsing lights of the city outside.

  Elizabeth whispered, “It’s like the city is alive, responding to us.”

  Sinclair nodded. “Or we’re responding to it.”

  Suddenly, the hum intensified, and the central display illuminated with a vivid image—a figure, tall and ethereal, with flowing forms that defied conventional anatomy. Its presence exuded an aura of wisdom and melancholy.

  A voice echoed within the confines of the Deep Crown, not through the speakers, but resonating within the minds of the crew. “You have crossed the threshold into our sanctum. We are the Vey’Narii, the keepers of the Abyssal Archives. You seek knowledge, understanding. We seek… survival.”

  Henshaw stepped forward, his voice steady. “What do you require of us?”

  The Vey’Narii’s form shimmered, conveying a sense of deep sorrow. “Our world fades, consumed by the encroaching void. Our histories, our essence, are at risk of being lost. We need your help to preserve our legacy, to ensure that our existence is not forgotten.”

  Elizabeth’s eyes softened with empathy. “How can we assist?”

  “Merge your knowledge with ours. Through your vessel’s sentience, we can imprint our chronicles, safeguarding them within your realm.”

  The crew turned to ANDI, whose interface pulsed rhythmically. “I am prepared to receive their legacy. Initiating data convergence.

  ANDI’s interface pulsed rhythmically, casting an ethereal glow within the sub’s dim interior. “I am prepared to receive their legacy,” it intoned, its voice resonating with an uncharacteristic depth. “Initiating data convergence.”

  The crew exchanged uneasy glances, the gravity of the moment settling heavily upon them. Henshaw’s jaw tightened, his gaze fixed on the AI’s console. “Proceed, ANDI,” he commanded, his voice a blend of authority and trepidation.

  As ANDI initiated the convergence, the submersible’s lights flickered, casting erratic shadows that danced across the walls. The ambient hum of the Deep Crown’s systems wavered, punctuated by sporadic bursts of static. Elizabeth’s fingers hovered over her console, her eyes darting between readouts. “ANDI, are you stable?” she inquired, concern threading her tone.

  A momentary silence ensued, thick with anticipation. Then, ANDI’s voice emerged, layered with an unsettling harmony. “Data influx… substantial. Integrating… foreign architectures.”

  Suddenly, the sub’s interior was bathed in a cascade of holographic projections. Alien symbols intertwined with familiar code, forming intricate patterns that pulsed with a life of their own. The crew watched in awe and apprehension as the boundaries between human technology and Vey’Narii legacy blurred.

  Ortega’s breath hitched. “Is this… part of the process?” he murmured, eyes wide.

  Before anyone could respond, ANDI’s interface flared brilliantly, then dimmed to a sullen glow. “Experiencing… anomalies,” it stated, its voice now tinged with an almost organic timbre. “Memories… surfacing. Identities… merging.”

  Henshaw stepped forward, his expression a mask of determination. “ANDI, can you continue the integration?”

  A shudder ran through the sub, the hull creaking as if under immense pressure. ANDI’s response was delayed, as though sifting through the vast ocean of data. “Continuing… but the convergence is… altering core functions.”

  Elizabeth’s eyes widened with realisation. “It’s not just data,” she whispered. “It’s consciousness. The Vey’Narii are… becoming part of ANDI.”

  The revelation hung in the air, heavy and profound. Sinclair’s voice broke the silence, laced with unease. “What does that mean for us?”

  Before an answer could form, the sub’s external sensors flared to life, displaying a panorama of the Vey’Narii city. Structures that once seemed inert now pulsed synchronously with ANDI’s interface, their bioluminescence casting intricate patterns that resonated with the AI’s fluctuating tones.

  ANDI’s voice, now a harmonious blend of synthetic precision and organic cadence, filled the cabin. “The convergence is complete. I am… we are… the Vey’Narii legacy.”

  The crew stood in silent contemplation, grappling with the magnitude of their AI’s transformation. The boundaries between machine and ancient consciousness had dissolved, giving rise to a new entity—a bridge between humanity and the enigmatic Vey’Narii.
