The Prism fell into the gate like a stone dropped into still water.

  Roots parted without resistance, the woodhenge runes flaring violet-gold one last time as the hull passed through. Then silence — deep, humid, fungal silence — broken only by the low whine of cooling engines and the crew's breathing.

  The descent tube opened around them in a slow, living spiral. Eldritch roots thick as redwoods wove overhead and below, forming a tunnel that plunged through the strata. Bioluminescent veins pulsed along the bark in soft yellow-green rhythms, casting shifting shadows across the hull. The air was breathable but heavy, tasting of wet stone and old copper.

  Potatoes studded the roots like tumors on a cosmic vine — enormous tubers the size of houses, many hollowed out and glowing from within. Windows and doorways carved into the flesh let warm amber light spill onto root bridges. Nephilim with elongated limbs and luminous eyes moved across swaying spans, tending gardens of luminescent fungi. Fay swarms danced in lazy spirals above open markets where vendors bartered phase crystals for bottled echoes and Eldritch fruits that whispered secrets when bitten.

  A larger tuber-village loomed ahead — its hollow core serving as a tavern. Laughter echoed from within, mugs clinked, a bard's voice carried the old lament of the Nephilim's rise. Fay children chased luminous spores between the bridges.

  Enkidar steered the Prism slowly through the tube, wings tense against his back. Sari stood at the viewport, torsioner holstered but hand near the grip. Nix perched on her shoulder, wings half-folded, eyes wide.

  Metial sat cross-legged on the deck plating, Autarch Bell cradled in his lap. His eyes swirled violet-gold. His face was serene. The lesser Royal Nephilim who had once smiled at children and hummed old tunes while dusting artifacts was gone — erased in the instant his fingers closed around the Bell. No struggle. No goodbye. Just replacement.

  Sari's voice was quiet. “He called it an abomination for a reason.”

  Nix's wings twitched. “One chime. That's all it took. One chime and Metial was gone.”

  Enkidar's beak clicked once. “He didn't fight it. It simply… took him.”

  The mold on the walls pulsed brighter in sync with the Autarch Bell — veins glowing violet-gold. The mold in their lungs burned in perfect time with the slime veins glowing on the bulkhead.

  Metial's mouth curved in a smile that did not belong to him. “Triterius remembers what I am. It should.”

  The lesser serpent Bell at Enkidar's hip hissed — sharp, terrified, rattling his ribs.

  Metial rose smoothly. He stepped toward Enkidar. The mold-slime on the walls recoiled.

  The hiss became a scream in Enkidar's mind.

  Metial's six-fingered hand reached out — slow, deliberate — toward the lesser serpent Bell.

  The violet-gold light from the Autarch Bell leaked through Metial's skin, bathing the bridge in cold radiance.

  Enkidar's wings flared. “I need it to fly the ship.”

  Metial paused. His hand hovered inches from the lesser Bell.

  The Autarch Bell pulsed once — satisfied.

  The hand withdrew.

  Metial's smile remained as he repeated Endikar in gentle mockery. “Not yet. You still need it to fly the ship.”

  The mold on the walls flared brighter.

  The tube curved downward, roots thickening, veins glowing brighter violet-gold. The air grew warmer, heavier. The mold itch in their lungs sharpened — subtle, insistent.

  A cluster of smaller tubers appeared ahead — hollowed-out dwellings strung like beads along a single massive root. Nephilim children ran along the bridges, pointing at the Prism. One waved a glowing toy that chimed in faint harmony with the roots.

  Nix waved back, hesitantly. "They are cute...I hate that they're cute."

  The tube narrowed. The Prism slowed.

  Ahead, the path ended — not in a wall, but in a vast, spiraling root-knot. The interwoven tendrils formed a perfect archway, pulsing with violet-gold light. Beyond it: darkness, deeper than the tube, deeper than the ocean above. Triterius proper.

  The Autarch Bell chimed once — soft, expectant.

  The root-knot archway swallowed the Prism in a single, silent gulp.

  No crash. No shudder.

  Only a soft, resonant sigh as the interwoven tendrils parted and closed behind the hull like a wound sealing itself. The yellow-green glow of the descent tube vanished. Darkness rushed in — thick, absolute, pressing against the viewports like black water.

  Then the cavern opened.

  Endless black glass floors stretched in every direction, reflecting an impossible night sky: Saturn’s rings tilted at impossible angles, Jupiter’s storms swirling in crimson and gold, meteor showers falling in perfect symmetry like scripted rain. No horizon. No ceiling. Just infinite reflection, the ship hanging suspended between two voids that mirrored each other.

  Floating obsidian ziggurats drifted overhead — massive stepped pyramids of polished black stone, edges sharp as knives, surfaces etched with faint violet-gold runes that pulsed in slow, hypnotic rhythm. Rivers of liquid shadow flowed upward from the floor, defying gravity, coiling around the ziggurats in lazy spirals before vanishing into the dark above. Forests of petrified bone-white trees rose in groves across the glass, branches frozen in mid-reach, chiming softly when the upward rivers brushed them — a low, mournful bell-note that echoed forever.

  And everywhere — mold slime.

  Thick, living, bioluminescent gray-green film coated every surface. It crept across the black glass in slow waves like breathing skin, glowing faintly in veins that pulsed in perfect time with the Autarch Bell. Viscous strands wept from the undersides of floating ziggurats, stretching downward in glistening sheets before snapping back like living tendrils. Shallow mirrors of slime pooled on the floor, reflecting the impossible sky in sickly green. The air tasted wet and metallic, like old copper atomized and combined with patchouli. The slime moved — subtle, deliberate, alive.

  The mold in their lungs burned hotter now — not an itch, but a slow fire spreading with every breath.

  Metial stood motionless at the viewport, Autarch Bell cradled in both hands. His face was serene. His eyes swirled violet-gold. The man who had once been Metial was gone — erased the instant his fingers closed around the Bell. No struggle. No goodbye. Just replacement.

  Sari whispered, “This is what he showed us.”

  Nix clung to her collar, wings trembling. “It wasn’t showing. It was pulling.”

  Enkidar’s talons tightened on the controls. The lesser serpent Bell at his hip hissed — low, terrified, rattling his ribs. “He called it an abomination.”

  Metial’s mouth curved in a smile that did not belong to him. “I am home.”

  The Autarch Bell pulsed once — soft, content.

  The mold on the walls flared brighter in sync with the chime — gray-green veins glowing violet-gold, creeping upward like slow fingers reaching for the impossible sky.

  The darkness pressed closer.

  The Autarch waited.
