The reef had stopped singing.
Not completely, water always carried sound, but the rhythms were wrong. No chimefish clicks. No duskcall from the ridge vents. Only the slow murmur of current against coral and the distant hum of mana glyphs straining to hold their patterns. Even the silence felt heavier, as if the ocean itself held its breath.
I stood outside my old planter dome, watching two apprentices drag away unused harvest rigs. My name had been scraped from the entrance shell. The etching was fresh, the edges sharp. Planters moved on quickly when someone left. They had to.
Once you donned Watcher gear, even once, you didn't go back. It changed how people looked at you, as if you carried a shadow no light could wash off.
I didn't linger. The corridors no longer felt like home, just memory. I pushed into the current, letting it carry me toward the ridge lanes.
A tide-runner streaked up from below, her fins cutting tight lines through the water. Purpose shimmered in every movement. She stopped just long enough to thrust a sealed glyph shard into my hand. "Direct to you. Marked urgent."
The seal bore Yera's mark. I cracked it open.
Southern trench scan team breached. Runners unresponsive. Secondary unit deployed. Report immediately to glyphbay six. –Yera
No signature. None needed.
The knot in my chest tightened. I turned and swam hard, cutting through the middle channels, ignoring the startled looks from the workers I passed. Every stroke burned, not from exertion, but from the tension coiling deeper.
The glyphbay pulsed with layered runes when I arrived, defense, coordination, resonance sync, each glow overlapping the next. The air felt sharp with charged mana. Yera stood by the central pillar, fastening her armplate beneath a coil-thread gauntlet. Two other Watchers waited beside her, both older, their crescent-blades etched in shellbone patterns.
"You flank center," Yera said, eyes flicking toward me but not softening. "Hold formation. Do not engage unless I signal. If contact breaks, pull glyphthread and flare twice before retreat."
I adjusted the shoulder band of my armor. It still felt foreign, like it knew I hadn't earned it yet. "Understood."
Moments later, we launched into the current. Water split around us in streaks of turbulence, our formation slicing clean lines through the darkening reef. I matched their rhythm, gliding just behind and to the left, keeping my eyes on the glow pulsing faintly from their weapons.
The reef shifted as we descended. Kelp curtains gave way to jagged coral veins, the light narrowing into thin beams. Scar-lines marked the walls like forgotten script. Somewhere above, I felt the hum of the city, but it grew fainter the deeper we dove.
The breach marker shimmered beyond a sunken shelf. Its glyphlight was dimming, meaning the scout team had placed it but never reinforced the ward. That alone made my stomach knot.
We slowed together, blades at the ready.
The trench opened into a wide basin, half-lit by highbeam tideglow, half shadowed by shellrock. Stray fruit pods floated among the rubble, half-rotted, likely shaken loose by a tidequake. The silence here wasn't natural. It felt forced, as if something had told the reef to hold still.
"What's that?" one of the Watchers murmured, pointing to a driftvine net hanging from the spires.
Yera swam closer. "A rig. Salvage-grade. Someone was harvesting."
"No runner logged a second attempt," I said. "This zone isn't cleared."
We knew before we saw him.
A flicker at the edge of the rubble, controlled, not panicked. Watching.
The Exile stepped from a crevice between shell formations.
He wore a fraycloak, patchwork of barnacle thread, fruit stalk, and silt-dyed scaleplate. Cracked lenses shielded his eyes. In his hands, a net of bruised tidefruit pods leaked faint mana vapor. He didn't raise a weapon.
Yera raised hers.
"Identify yourself," she said, blade glinting.
"I'm not here for you," the Exile replied, voice flat but clear. "I came for what your reef lets rot."
"You're trespassing," the Watcher on my left snapped. "You know the consequence."
The Exile's mouth tightened. "I know what you prefer. Better the fruit rot than our hands touch it."
"You abandoned the reef," Yera said coldly. "You abandoned the rites."
"No," the Exile said quietly. "Only the city. Never the god. Never the fruit."
His words struck something deep. I spoke before I could stop myself. "You still feed it?"
He looked at me then, really looked. Behind the cracked lenses, his eyes gleamed pale and tired—not wild like we were taught, not hateful. "Someone must."
He turned to leave.
The younger Watcher moved too fast, loosing a warning bolt that clipped the Exile's shoulder. The pods scattered, spilling glowing trails. The Exile flared his fins, spun, and hurled a coral shard with deadly precision. It cracked the Watcher's mask, fracturing but not breaking through.
"Enough!" Yera shouted.
But the Exile was already gone, slipping into the silt folds with unnatural ease, leaving only a thin thread of blood behind.
We hovered in silence. The broken fruit drifted down like bruised stars.
Yera cursed and activated a scan flare. "Mark the zone. Shellmaster review later." She glanced at me, eyes unreadable. "You alright?"
I nodded, but it was a lie.
The swim back felt longer, heavier. My limbs ached, but not from effort. Something deeper had settled in me: confusion, conflict, guilt. I couldn't stop replaying his words.
Someone must feed it.
That night, the reef shook.
Not a quake. Not a collapse. A pulse.
I jolted upright in my cot, heart pounding. The walls vibrated with low-pressure distortion. Outside, red glyphs flared across the lanes. Sirens pulsed in burst patterns, Watch-grade alerts.
I didn't think. I moved. Training drilled into me: when the shadows breach, you don't hesitate.
The reef was chaos. Watchers, guards, artisans, everyone swam toward the southern channels. Tidecaster signals flared, painting currents with jagged warning light.
Shellbinders pulled shutter glyphs over nursery domes, hands shaking. Inside, hatchlings stirred in their pods, pressing tiny hands against glass. Elders crouched by speaking reefs, chanting fractured hymns through voice flutes. The tones cracked, uneven, as if the reef itself had forgotten how to answer.
Apprentices fumbled with defensive flares, glyphlight sputtering as they tried to sync strands. A runner streaked past me, bleeding from one fin, eyes wide with terror.
I gripped the cot-harness tight, blade at my side, as the water thickened with fear. Every sound echoed sharper. Every shadow stretched longer.
This wasn't a drill.This wasn't a false alarm.
The corruption had taken form, rot made flesh, moving through the reef.
And they were already inside.
