  "prompt": "A dark, brooding, and atmospheric square 1024x1024 image suitable for an audiobook cover. The scene depicts a lone, stoic figure standing silhouetted against a stark, industrial urban landscape at dusk. The figure, identifiable by a subtle but imposing physique, is facing away from the viewer, looking towards a sprawling, dimly lit city skyline. Rain is subtly streaking down, creating reflections on wet pavement in the foreground, suggesting a gritty, noir-inspired mood. Elements of the city appear slightly disheveled or weathered, hinting at hidden dangers and secrets. The color palette is dominated by deep blues, charcoal grays, muted browns, and hints of dim, diffused orange or yellow light emanating from distant windows or streetlamps. The overall composition is minimalistic yet powerful, conveying a sense of isolation, vigilance, and impending conflict. The lighting should be dramatic, with strong shadows and a limited light source, enhancing the mysterious and suspenseful atmosphere. NO text, NO letters, NO words, NO title, NO author name — only visual artwork.",
