CHAPTER 10: THE FIRST SALT CRYSTAL
The trench was a graveyard of giants.
As Rin dived deeper into the vertical fissure, the natural geological basalt walls gave way to the skeletal concrete and twisted rebar of a swallowed epoch. This was the drowned metropolis of the old world. Skyscrapers, once built to scrape the heavens, now stood like titanic, decaying headstones in the dark. They were draped in thick, weeping blankets of black kelp, their hollow windows serving as nests for blind, albino crabs and pale, undulating sea worms.
Rin glided through this silent abyss with supernatural grace. She no longer needed to kick frantically; her body moved in perfect harmony with the thermoclines, her basalt-scaled hands steering her through the jagged metal canyons. The water here was under immense, crushing pressure—a weight that would have instantly flattened her old copper diving suit like an empty tin can. Yet, to Rin, it felt like a heavy, comforting embrace. Her gills, glowing slits along her collarbones, pulsed rhythmically as they filtered the freezing, mineral-rich water.
[The key is near, Echo,] the Guardian’s voice whispered in her head, its tone vibrating with a cautious urgency. [But the Blight has already begun to coagulate here. The water is thick with the scent of the Maw. Be swift.]
Rin slowed her descent, hovering near the shattered spire of what had once been a magnificent Gothic cathedral. The building was colossal, its stone arches cracked and colonized by deep-sea organisms.
She swam down through the collapsed stained-glass ceiling, entering the grand nave. Inside, the silence was absolute, heavy with the dust of centuries. The light from her glowing green veins cast long, eerie shadows across the ruined stone pews and decaying statues of forgotten saints.
At the far end of the nave, resting upon a ruined altar of cracked marble, sat a rusted brass reliquary. And inside it, pulsing with an intense, pristine light, was the First Salt Crystal.
The moment Rin approached, her eyes widened. The crystal was raw and jagged, the size of a human skull, yet it possessed a geometric perfection that defied nature. It did not glow with the soft, biological teal of the deep-sea algae; it radiated a brilliant, blinding blue-white energy.
As she drew closer, she felt the temperature around her shift. The freezing, salt-heavy water felt suddenly fresh, carrying the unmistakable, crisp scent of a cold sea breeze from a world before the cataclysm.
The black, oily veins of the Blight that clung to the altar and the surrounding stone pillars withered and turned to pale ash the moment the crystal’s light touched them.
"The Heart of the Ocean," Rin whispered, the water carrying her soft words.
She reached out her hand, her dark, basalt-plated fingers gently closing around the jagged edges of the crystal.
The moment her skin made contact, a violent jolt of pure, raw energy surged up her arm. It wasn't the warm, ancient flow of the Guardian, but something sharper, colder, and incredibly clean. It was the primordial frequency of the ocean’s origin. The glowing green runes on her neck flared, turning a brilliant, blinding white.
[You have it, Echo!] the Guardian’s voice echoed, but the warmth in its tone was suddenly cut short by a wave of sharp static. [Wait... they are here. They have closed the exit!]
Rin spun around in the water, clutching the heavy, pulsing crystal to her chest.
At the shattered ceiling of the cathedral, the soft blue light was gone. It had been replaced by a suffocating, sickly purple haze that poured into the nave like liquid poison.
And within that purple fog, they appeared.
Dozens of the Drowned were descending through the ruined roof. Their pale, waterlogged bodies writhed in the current, their unnaturally long limbs twitching as they swam. Their faceless heads jerked in unison, their circular, needle-fanged maws expanding and contracting in a horrific, clicking rhythm.
They did not fear Rin. They feared the light she held. They wanted to drown it.
[Feed the Maw...] the wet, gurgling chorus of the Blight roared inside Rin’s head, a chaotic wave of static that made her temples throb. [Extinguish the spark... the dark is hungry...]
"No," Rin thought fiercely, her amber eyes flashing with a cold, protective instinct. "You won't take this."
She kicked her legs, launching herself upward. But the Drowned were fast. One of the pale monsters lunged from the shadows of a stone pillar, its webbed claws reaching for her ankle. Rin swerved mid-water, her basalt-scaled forearm swinging outward. Her hardened claws sliced clean through the creature's pale, bloodless wrist.
The monster let out a silent, bubbling shriek as thick, black slime leaked from the wound. But three more took its place, diving toward her from the vaulted arches above.
Rin held the Salt Crystal forward. "Get back!" she commanded, her mental voice carrying the authority of a rising tide.
She channeled her own bioluminescent energy into the crystal. The jagged stone responded, unleashing a violent, blinding pulse of blue-white light that expanded outward like an underwater shockwave.
FLASH.
The wave of pure energy hit the descending Drowned. The moment the light touched their pale, mutated flesh, the black veins of the Blight inside them began to boil. The creatures thrashed violently, their bodies dissolving into clouds of dark ash that were instantly swept away by the current.
But the victory was short-lived.
A shadow far larger than any skyscraper suddenly fell over the cathedral ruins. The water pressure in the nave skyrocketed, pressing down on Rin with a sudden, suffocating force.
The ceiling of the cathedral didn't just collapse; it was pulverized.
A massive, bone-plated snout crashed through the ancient stone arches, sending giant blocks of marble tumbling into the darkness. It was the White Sea Elephant.
The infected titan had descended into the trench, guided by the desperate distress signals of the Blight. Its massive, milk-white eyes were rolling in its socket, weeping rivers of black slime. The purple pustules on its skin were pulsing rapidly, releasing thick clouds of toxic, oily rot that threatened to overwhelm the pristine light of the crystal.
The titan focused its blind gaze directly on Rin. It felt the agonizing, purifying light of the Salt Crystal, and it wanted to destroy it.
The massive beast opened its cavernous mouth, preparing to swallow Rin, the crystal, and the entire cathedral in a single, crushing gulp.
[The core of the infection is behind his skull, Echo!] the Guardian's voice screamed through the static. [You must strike now! Drive the crystal into the black node, or we lose him forever!]
Rin looked at the massive, approaching maw, then down at the brilliant, pulsing crystal in her hands. She did not back down. She did not run.

"Hold on, big guy," she whispered into the dark water. "I'm going to make the noise stop."
With a powerful, defiant kick, Rin launched herself directly into the path of the oncoming titan, her white-glowing form a solitary streak of light diving straight into the mouth of the leviathan.
