12:05 Hours. The Thermal Plume.
The ROV sat steady in the updraft, its high-grade titanium chassis and manipulator arm handling the 350°C venting from the black smoker without issue. Elena moved the primary arm with surgical precision. The diamond-grit scraper moved toward the MC's indigo flank, targeting the area just behind the massive pectoral wing.
On the 4K feed, the creature's hide was a landscape of dark, metallic geometry. The hexagonal plates remained still as the arm approached; the MC was still anchored by the square claws buried in the basalt, his eyes shut in a metabolic trance.
12:10 Hours. The Contact.
The titanium scraper touched the indigo flank. Elena applied steady, lateral pressure, dragging the abrasive edge across a single large plate.
The sound was captured by the ROV's high-gain hydrophone—a dull, metallic rasp that vibrated through the water. As the scraper pulled away, several translucent, iridescent flakes of the skin sloughed off. The suction sampler engaged, whisking the material into the pressurized canister.
12:12 Hours. The Coagulation.
"Got it," Aris whispered. "Elena, zoom in on the scrape site now."
Under the high-powered optical zoom, they watched the biological response. The site didn't bleed red. Instead, a thick, glowing crimson fluid—the same substance filling the MC's glowing channels—oozed into the minor breach.
The moment the fluid hit the surrounding seawater, it underwent a rapid phase-shift. It solidified into a glassy, protective seal that matched the texture of the surrounding hexagonal plates in seconds.
"It's a thermal-conductive polymer," Aris noted. "It reacts to the temperature drop by instantly turning into an organic solder. He's self-repairing."
12:15 Hours. The Detachment.
The vibration of the scraper or the persistent hum of the ROV's thrusters finally broke the trance. The MC's massive gold-flecked eye slid open, staring straight ahead into the darkness.
He didn't turn to investigate the ROV. Like a whale surfacing or shifting grounds, he simply prepared to move. He flexed the musculature in his forward limbs. The square, white claws that had been driven deep into the volcanic rock began to grind. The sound was a deafening screech of mineral on chitin as the basalt tower spiderwebbed with fresh cracks.
With a final, powerful heave, he unhooked his claws.
A massive cloud of silt and volcanic ash kicked up from the seafloor, momentarily white-washing the 4K feed. The ROV was buffeted by the sheer displacement of water as 30 meters of biological weight detached from the vent.
Instead of turning, the MC beat his massive pectoral wings once, a slow and heavy stroke that pushed him forward and away from the vent. He began a gradual, steady ascent, leaving the ROV behind in the settling silt.
