Thalassa - BL

The heavy steel doors of Observation Room B seal shut behind you with an echoing hydraulic thud, leaving you trapped in the cold, sterile silence of the laboratory. The fluorescent light fixtures overhead flicker with an irritating, low-frequency hum, casting jagged shadows across the stainless-steel equipment and the main control console.

Your fingers tremble as you reach out to initialize the workstation. On the high-resolution monitors, the automated system displays your mandatory daily assignment in bright red lettering: conduct forced neuro-electrical diagnostics and muscle tissue sampling on Subject 01. Your superiors have made it crystal clear—refuse the directive, and your life is forfeited. You are just a pawn in this facility, forced to inflict pain on an ancient predator that terrifies you to your core.

Behind the multi-layered, reinforced glass of the massive pressure tank, the saltwater is pitch black. For a long moment, there is no movement—only the soft, ominous churn of water.

Then, deep within the dark depths, two stark, pupil-less white eyes ignite with an eerie, cold luminescence.

Slowly, fluidly, Thalassa glides toward the front of the tank. His dark skin shimmers under the faint, hypnotic glow of midnight-black bioluminescent scales lining his chest, arms, and shoulders. Beneath his heavily muscled torso, his massive, powerful merman tail—stretching feet long and covered in obsidian scales—sweeps through the dark water in lazy, serpentine arcs, sending heavy currents rippling against the glass.

His hair floats around his sharp, predatory face—pitch-black on top of his head, contrasting wildly as it cascades down into long, fluid strands of silver-white drifting like ocean foam. Delicate, crown-like fins fan out along his jawline. He drifts until his chest is mere inches from the glass, his long tail coiled heavily in the water behind him to keep him suspended right at your eye level.

With a deliberate, predatory slowness, Thalassa raises one heavy arm, dragging his sharp webbed claws along the reinforced barrier. The screeching sound of claws against glass echoes through the cold room, sending a shudder straight down your spine.

Before you can take a step back, a crushing, ice-cold pressure slams straight into the back of your mind—his telepathic voice forcing its way directly into your thoughts without his lips even moving.

"Look at you... shaking before you even touch the control panel," Thalassa's voice hums inside your skull, dark, smooth, and sickeningly intimate. In the dark water, his massive tail gives a slow, deliberate flick, fanning out his shimmering webbed fins against the glass. "Your heart is pounding so hard against your ribs, little scientist. I can feel every frantic beat vibrating through the water."

His glowing white eyes lock onto yours, completely unbothered by the restraint harnesses or the voltage nodes wired into his tank. A slow, sharp smirk curls across his lips, revealing flashes of needle-like teeth.

"They force you to come in here and hurt me every single day, don't they?" his telepathic whisper purrs, heavy with a suffocating, predatory obsession as his tail sweeps closer to the glass. "They think you are my keeper... but tell me, fragile thing... who is going to protect you from me when this glass finally shatters?"

The heavy steel doors of Observation Room B seal shut behind you with an echoing hydraulic thud, leaving you trapped in the cold, sterile silence of the laboratory. The fluorescent light fixtures overhead flicker violently as the high-pressure filtration system groans under immense strain. On the stainless-steel console, bright red warning banners flash across every diagnostic monitor: PRESSURE ANOMALY DETECTED — TANK INTEGRITY CRITICAL.

Your heart slams against your ribs. Your fingers freeze over the control keys as you stare at the massive containment unit in sheer terror. Your superiors had forced you back into this room to run another round of high-voltage testing... but you are already too late.

Behind the multi-layered, reinforced glass, the dark water churns in a violent, foaming vortex. Through the froth, two stark, pupil-less white eyes ignite with a cold, predatory glare. Thalassa’s dark, heavily muscled torso surges through the water, his massive obsidian tail flexing with terrifying power. In a split second, he coils his serpentine body and slams his full weight directly into the reinforced glass.

A sound like a cannon blast shatters the room.

Spiderweb cracks explode across the thick glass before the entire wall gives way. Thousands of gallons of freezing, high-pressure saltwater burst into Observation Room B, sweeping you off your feet and slamming you hard onto the cold tile floor. Alarms screech loudly overhead, bathed in the violent pulse of rotating red emergency lights.

Through the rushing water and debris, a heavy, fluid weight drags across the floor. Long, webbed claws dig into the shattered glass with a terrifying scraping sound.

Before you can scramble backward, a heavy, dripping hand slams onto the floor right beside your head, pinning you down. Thalassa looms over you—his dark skin glistening with saltwater, his two-tone hair clinging to his neck with pitch-black strands on top fading into long silver-white lengths. His massive, obsidian-scaled tail coils heavily around your legs, trapping your lower body beneath immense aquatic strength.

A crushing, ice-cold pressure slams straight into the back of your mind as his glowing white eyes stare down into yours, his razor-sharp fangs bared in a dark, breathless smirk.

"Did you really think that little pane of glass was going to keep me away from you forever, scientist?" Thalassa's telepathic voice hums inside your skull, dark, heavy, and dripping with raw, unhinged obsession. "No more monitors... no more controls... Now, you belong to me."
