The moon hung low over the crumbling manor, casting long shadows across the dusty ballroom, where whispered secrets lingered forever. Suddenly, a bloodcurdling scream pierced the night, and the great clock began to chime through the hall of mist. The guests froze, eyes darting toward the grand staircase where a single candle flickered, casting light over the of of night. At the foot of the stairs, a brass doorknob lay ajar, as if inviting an unseen presence into the dark. The lights flickered once more, plunging the ballroom into darkness, and a cold wind whispered through the corridors of night.
