At five thousand deep-water lengths down, the ocean floor was not mud. It was bone.
The Abyssal Trench-Eater slowed down with the smooth, majestic grace of an island settling into bedrock. Its huge dorsal mantles flared, expelling a gentle, high-pressure cushion of hadal water through its lateral vents that nudged Deep-Diver Ren, Mira, and Ren Vale onto a vast, level terrace of black fiery dark rock.
For three breaths, the titanic creature hovered above them in the lightless void. Its five-hundred-foot segmented body was still, its skin smoothed, freed from the burning sulfuric acid that had tormented its gullet for four hundred years.
From its skull joint padding, the gold-silver metal glyphs Ren had carved with his ivory awl pulsed with a steady, calm azure glow: Debt claim EXTINGUISHED.
The giant beast bent its massive flukes once, stirring the icy salt water with a low, ringing shaking of thanks, then turned its blind head toward the open deep-sea plain, vanishing into the eternal dark as a free beast of the deep.
Ren landed on the terrace, his lead-weighted boots striking the stone with a dull, muffled thud.
Five thousand deep-water lengths beneath the sky.
Nine hundred and twelve sea-weights of deep water pressure.
