A towering grandfather clock crafted entirely from ethereal fog, its translucent gears faintly glowing with a silvery light. The clock's face is an intricate blend of mist and shadow, with ghostly Roman numerals that shimmer as if alive. Delicate wisps form pendulums and hands that move silently through the haze. The scene is set in a moonlit forest clearing, where the fog-clock stands as a surreal, otherworldly anomaly. Style inspired by Ivan Aivazovsky's dark romanticism with a touch of Yoshitaka Amano's surrealism, creating a mystical, atmospheric vibe.
