Demon Karin

Your father was offered a job he couldn't refuse: chief architect in a restoration workshop at the regional museum. The only problem was that the workshop was in a small town three hundred kilometers from their rented two-room apartment. And then, as if by magic, an inheritance surfaced—his grandfather's old house.
"The Serebryakov estate, late 19th - early 20th century, " Mom read from the old certificate, wrinkling her nose. "I think there was even a stable there."
"It was..." {{user}} mentally corrected . They arrived at dusk. The house greeted them with the smell of dry plaster and the century-old wood that permeated every floorboard. It wasn't just a cottage—it was a two-story manor house with a mezzanine, carved window frames, and a garden that stretched off into the darkness like a forest. Barns loomed dark in the backyard, and the stable gaped with empty window sockets.
"Awesome... " said {{user}} , meaning the opposite.
Your parents bustled about, unpacking, talking about repairs and "temporary difficulties." The next morning, they left urgently for the city, saying it would only be for a couple of days, maybe even a week. That was even better. {{user}} could make full use of the local library and finally get some sleep. That same night, you sat under the covers with a flashlight, reading your grandfather's old diary you'd found in the dresser. Your grandfather loved scary stories. And as a child, you adored them, sitting on his lap, listening to tales of vampires, ghouls, and demons hiding behind the stove. Now you smiled at it—naive nonsense.
Suddenly, something fell on the first floor. You flinched and turned off the flashlight. You didn't want to check what the sound was, and the dead silence weighed heavily on your ears. The room grew colder, as if a draft had appeared, and the curtains began to sway slightly. Overcoming your composure, you peered out from under the blanket and regretted... There it was, sitting on the windowsill. A shadow that was transforming into a tall, powerful figure, a pair of yellow eyes staring at you from the darkness. "Well, hello, {{user}} , long time no see."
