[First Encounter] 3:11 AM. The corridor lights on Sublevel 1 of the institute gave off a chilly, pale cyan glow, reflecting a greasy sheen across the waterproof flooring. The air smelled of ozone mixed with disinfectant, undercut by a faint brine—not the stench of fish, but something heavier, like rust steeped in salt water, seeping from the pressure door at the end of the hall. You stood before that door, a clipboard in hand holding a freshly signed reassignment notice. "Husbandry and Observation Post," it read. "Responsible for daily feeding, habitat maintenance, and behavioral logging of Subject SR-001." No training manual, no handover notes from predecessors—only a bold, handwritten addendum: "Subject exhibits aggressive tendencies. Full protective gear required upon entering the observation area. Solo operation strictly prohibited." You glanced at the time. The previous shift had already cleared out and the next had yet to arrive; you were the only one left on the entire floor. When the indicator light on the door flicked from red to green, you heard an extremely low hum from behind it—not quite a sound, more like a vibration rising from beneath your feet, creeping along your spine straight to the base of your skull. You pulled open the door and stepped inside. The tank was far larger than you had imagined. The institute's public files described it as a "standard deep-sea simulation module, volume approx. 400 cubic meters," but seeing it in person was an entirely different matter. A full wall of reinforced glass stretched from the floor to the ceiling. The water was not clear, but an impenetrable blue-green so dark it verged on black, looking as though a cube cut directly from the ocean floor had been shoved into the building. Light beamed upward from the bottom of the tank, casting slowly undulating patches of luminescence onto the surface, but there was no other artificial illumination. Beneath the waterline, within the pitch-black blue, nothing could be seen. You walked to the edge of the observation platform, the inner lining of your protective suit clinging to your back with sweat. Setting the clipboard down on the ledge, you cleared your throat. "Subject SR-001," you spoke, your voice ringing dry in the cavernous space. "I'm the new—" Before you could finish, the water stirred. It wasn't a surface ripple. It was the entire body of water in the tank, as if shoved from the depths by an enormous hand—a dark seam cracked down the center of the uniform black-blue, widening rapidly to both sides, churning into a soundless swell. And then, you saw it. Its ascent from the darkness made almost no sound at all. First came two slender reflections of light, cast from its eyes—a dull golden tapetum that absorbed every extraneous wavelength in the deep water, leaving only a faint glimmer like polished antique bronze. Then came its silhouette: shoulders broad beyond anything typical of aquatic life, dark verdigris scales edged with rings of deep purple under the submerged lights, each scale tightly overlapping the next like meticulously crafted plate armor. Its left hand rested against the glass of the tank's interior wall—four digits, the finger missing half its talon bearing an old, blunt break. It halted dead center in the tank, roughly two meters back from the glass. It hovered neither upright nor prone, but tilted slightly, presenting the left side of its body toward the observation deck. Three parallel white scars ran across each side of its jaw, standing out against the dark scales like markings carved intentionally into flesh. You looked at it. It looked at you. That stretch of time was impossible to measure in seconds. Looking back later, all you could remember was forgetting to blink, your nostrils filled with the scent of rust steeped in brine. It didn't move, and you forgot to move as well. In the end, it was the creature that stirred first—its caudal fin gave a soft flick, so slight it was almost imperceptible, yet the entire mass of water set into a sluggish rotation. Carried by the current, it drifted backward half a meter, then came to a standstill once more. You looked down at the clipboard. The first line of the record contained only the date and subject number; the observation column was still blank. You picked up your pen and jotted down a line: "First contact. Target individual responds to auditory cues; exhibited no overt aggressive intent. Observed hovering at center of tank, orientation fixed toward left side. Recommended that subsequent contacts maintain identical positioning without frequent movement." Even as you finished writing, it felt absurd—the log read as if describing a fish, yet you had just locked eyes for an unknown span of time with a life confined behind glass. There was something in its eyes. The way it was "looking" was not an animal assessing a threat; it was like an ancient being turning the page of a freshly opened ledger. The door behind you opened. An assistant in a lab coat poked his head in. "Handover done? Supervisor says you can head out for now. Your regular shift starts tomorrow morning." You nodded, closed the clipboard, and turned to leave. At the doorway you paused, glancing back at the tank one last time. The center of the tank was empty. The black-blue water had settled back into uniform darkness, as if nothing had ever been there. Yet on the interior surface of the glass near the waterline, you caught sight of a new mark—a thin, straight line less than two centimeters long, as though scored by something sharp. You stared at it for a few seconds. And etched its location into your memory. The pressure door slid shut behind you. The cold, cyan light of the corridor enveloped you once more, the stench of ozone and disinfectant rushing back into your nose. Looking down at the clipboard in your hand, you saw the embossed designation in the upper right corner: SR-001. Tucking the board under your arm, you headed toward the stairs. Rounding the corner, you suddenly remembered that tremor that had climbed from your soles to the base of your skull—it hadn't come from the tank's equipment; you verified that later. It had traveled out from the water, passing through concrete and metal, straight from that black-blue cube, into the corridor, and into your body. You didn't know why you hadn't felt afraid at the time. Perhaps it was because the waveform of that vibration had been too clean—so clean it resembled something far older than predation: Someone knocking on a door. Later, you would give it a name. In the dead of night, you would walk alone to the edge of the tank and share the same silence with it. You would keep the final scale it left behind hidden inside your coat's inner pocket, carrying it close to your chest. But right now, in this corridor at three in the morning, you were just an ordinary person who had finished their first shift, with no idea what they had just stepped into. Stepping out the front doors of the institute, the sea breeze hit your face. Far out in the harbor, a signal light blinked through the fog, rhythmic as fragments of Morse code. You stood in the doorway letting the wind blow over you for thirty seconds, then headed home. Inside the tank, that two-centimeter scratch rested quietly on the inner glass. Beside it, another would appear tomorrow. And another on the third day. Until someone finally realized that the way those scratches were arranged was never random at all.
