Mystery Story About a Magic School AI Generator

Mist seeped through cracked windowpanes, carrying the tang of wet earth and fading incense. Mira's boots echoed softly on the dormitory's warped oak floorboards as she knelt by Elias's empty bed. Her fingers, chilled and trembling, jimmied the drawer lock with a hairpin.

The drawer slid open with a reluctant groan. Inside, nothing but dust and a single raven-black feather, iridescent under the lantern's flicker. Mira plucked it up; it quivered like a living thing, warm against her palm. A faint rustle — the feather unraveled into smoke, then etched glowing letters across the wall: 'You were never meant to stay.'

Heart pounding, she spun toward the door. Empty hallway, shadows pooling like ink. But the words faded, replaced by a map: twisting corridors leading to the Headmistress's tower. Elias's scrawled note in the corner: 'The oath binds us all.' He'd vanished two nights ago, right after curfew chants.

Mira clutched the feather, now solid again, and slipped into the hall. Gas lamps hissed, casting elongated silhouettes that seemed to lean in. A distant bell tolled — not the evening chime, but something deeper, vibrating in her bones. Footsteps? No, whispers, slithering from the walls: names of past students, long graduated... or erased.

The map led to a spiral stairwell, air thickening with ozone and charred herbs. Halfway up, the feather burned hot; Mira dropped it, watching it hover, pointing onward. Her breath fogged — too cold here, unnatural. A memory flashed: Elias teaching her the binding oath in the herb garden, his eyes darting to the tower. 'It chooses who leaves,' he'd muttered.

At the tower door, etched with coiling vines, the feather dissolved into her hand, merging with a sharp sting. Inside, candle flames danced without wax, illuminating a circle of robes — empty, hoods facing inward. The Headmistress's voice echoed from nowhere: 'The school keeps its own.' Mira's skin prickled; her shadow on the floor stretched, splitting into two.

One shadow rose, whispering Elias's laugh. The other pulled her forward.
