A ghostly Banshee standing on a mist-covered cliff at night, overlooking a stormy sea. Her long white hair floats around her like smoke, and her tattered grey dress blends with the fog. Her eyes glow faintly with sorrow, and her mouth is open in a silent scream. Wind swirls around her, carrying the souls of the dead. The sky is heavy with dark clouds, lightning flickers in the distance, and crows circle above. The atmosphere is haunting, ethereal, and cold. High-detail, fantasy realism, cinematic lighting with cold blue and silver tones
