Chapter 86 - Abyssal Descent
The transition from the screaming tempest of the Pacific surface to the crushing silence of the Cascadia Trench was instantaneous.
I was strapped inside the titanium-reinforced hydrodynamic diving rig, breathing a pressurized trimix gas that hissed rhythmically through my rebreather. Twin high-output electric thrusters mounted on my back hummed with steady, controlled power, driving me straight down through the black water.
My heads-up display glowed with vital telemetry:
*DEPTH: 850 METERS.*
*WATER TEMP: 2°C.*
*HULL INTEGRITY: 100%.*
*SONAR CONTACT: BEARING 270, RANGE 400 METERS, DESCENDING.*
The *Titan-IV* was a dark, glowing needle slipping through the abyss ahead of me. Its external halogen lights cut through the dense marine snow—drifting particles of organic matter that looked like stars shooting past in deep space.
Clara was moving fast, riding the edge of the continental shelf down into the chasm where the oceanic crust plunged beneath North America.
"Marcus, do you read me?" Harris’s voice crackled through the ultra-low-frequency hydro-acoustic comms, heavily distorted by distance and water density. "...Fleet Command... USS *Kentucky* is fifty miles out... but they cannot intercept in time... you are on your own..."
"Understood," I transmitted, the acoustic mic picking up the vibration in my throat. "I have visual on her wake."
I pushed the thruster throttles to maximum. The torque pushed me downward at nearly ten knots—a reckless speed in deep water, where a single collision with a submerged rock shelf would shatter my pressure hull like an eggshell.
At twelve hundred meters, the trench narrowed. Massive walls of black basalt rose on either side, carved by millions of years of tectonic grind.
Suddenly, my sonar shrieked an active ping.
Ahead, the *Titan-IV* banked hard. Its external manipulator arm swung out, and a small, cylindrical canister separated from its belly.

*TORPEDO COUNTERMEASURE / ACOUSTIC DECOY DETECTED.*
The canister detonated not with high explosives, but with an immense shockwave of pressurized gas and acoustic noise designed to scramble sonar systems. The concussive wave hit my diving rig like a freight train, spinning me out of control in the pitch-black water.
