  "prompt": "A professional audiobook cover image in square 1024x1024 format. The visual style should be dark, atmospheric science fiction with a hint of noir. The central imagery depicts a vast, cavernous cityscape stretching downwards into darkness, illuminated by sparse, futuristic neon lights in cool blues and deep purples. Towering, monolithic structures made of dark, metallic material dominate the scene, suggesting immense scale and claustrophobia. Subtle hints of industrial pipes and ventilation systems are visible. In the foreground, silhouetted against the distant glow, is a lone, trench-coated human figure, facing away from the viewer, looking into the abyss of the city. A faint, almost ethereal glow emanates from a single, small metallic sphere or lens somewhere within the composition, hinting at robotic presence. The overall mood is one of mystery, isolation, and impending dread, with a deep, velvety darkness as the predominant color. The lighting is dramatic, with strong contrasts between light and shadow.",
