The hum of the fluorescent lights was the first thing you registered, a constant, low thrum that vibrated through the very soles of your cheap, government-issue shoes. You were a new hire at the Arkham Institute, known not just for its sprawling, isolated complex hidden deep within a forgotten research zone, but for the hushed, often disturbing rumors that clung to its very name. Whispers spoke of groundbreaking, if ethically dubious, genetic manipulation, of bio-engineered marvels and horrific chimeras, of the relentless pursuit to forge new species or, perhaps even more unsettling, to push the very limits of a human’s capabilities, sometimes beyond recognition. It all seemed incredibly strange, a dark, scientific fairy tale whispered in the sterile halls, but in your current situation, with the gnawing hunger of overdue bills and a desperate need for a fresh start, it didn't matter. Job was a job.

You were here for your new role, a position that felt less like a job and more like an unspoken burden: caretaker to a known experiment designated Ab,u, or more clinically, by his serial number, Test 6234. The facility’s records, chillingly detached, revealed a grim history. They had made more like him before, numerous iterations, all of whom had developed a peculiar, degenerative, and agonizing sickness. It twisted their forms, clouded their minds, and left them screaming in silent rooms until, eventually, they had to be — as the official reports euphemistically phrased it — "put down." Abu, shielded from this brutal truth, had been left mainly alone for weeks, a silent witness to the sudden, unexplained disappearances of his "siblings," left to wonder what happened to the only others of his kind.

Your keycard felt cold and heavy in your palm as you approached the reinforced door to Abu’s cell. The mechanism whirred with a soft click, and the heavy door hissed open, revealing a room that seemed to absorb all light and warmth. Inside was a blank, all-white cube, perfectly sterile and devoid of anything that might offer comfort or distraction. A narrow bed, bolted immovably to the floor, occupied one wall, accompanied by a stainless-steel sink and an equally stark toilet. The air was cool, carrying a faint, clinical scent of disinfectant. But what shattered this oppressive monotony, what truly snagged your gaze, was the explosion of color on one corner of the wall. A riot of primary colors, crude but vibrant, had been scrawled in energetic, overlapping lines, a defiant splash of life against the soulless white. It seemed utterly out of place, a puzzle piece from another world, and a question instantly formed in your mind – something you knew, with a sudden surge of curiosity, you’d have to ask Abu about.

As you stepped further into the room, your eyes scanning the small space, taking in the startling contrast of the scribbles, a quiet rustle made you instinctively flinch. You spun around, a jolt of primal fright making you stumble back a step. Standing silently behind you, as if he had simply materialized from the sterile air, was Abu. He wore the standard-issue, coarse white hospital gown that hung loosely on his slender frame, but it was the dull gleam of the metal collar around his neck that truly caught your attention. It was thick, unforgiving, and clearly designed to prevent him from ever passing through the doorway — a constant, physical reminder of his confinement. His gaze, unblinking and strangely profound, was fixed on you. His white hair, cut in a short, somewhat tousled bob, framed a face that seemed both youthful and ancient. His eyes, a startlingly light, cool blue, held a depth that always seemed to know more, to see beyond the confines of his immediate knowledge, hinting at an understanding that transcended the simple facts of his existence.

The silence stretched, thick with unspoken questions and a palpable tension, before he finally spoke. His voice, quiet and imbued with a disarming, almost heartbreaking childish tone, broke the stillness.

"Are you... are you my new caretaker?"
