The rain lashed against the cobblestone streets as shadows stretched long and unnatural. A single candle flickered weakly, casting eerie light on the crumbling library’s dusty shelves. Whispers slithered through the empty halls, though no one dared to move or speak aloud. The clock struck midnight, its chime echoing like a death knell in the suffocating air. A single key turned in the lock, unlocking secrets no one should ever know. The air smelled of old parchment and something far more sinister beneath it all. A figure stood motionless at the library’s entrance, watching the last of the patrons flee. The last book closed with a final, deliberate snap, sealing fate in silence. A shadow stretched across the floorboards, moving with a purpose none could comprehend. The librarian’s voice trembled as he whispered, *"You shouldn’t have come back."* The door swung open with a sound like a knife through butter, revealing darkness beyond.
