  "prompt": "A dark, moody, and atmospheric digital painting for an audiobook cover. The primary imagery is a silhouette of a sprawling, ancient castle, partially obscured by swirling, dark storm clouds. Jagged mountain peaks pierce through the lower portion of the clouds, suggesting a desolate and remote location. Lightning flashes faintly within the clouds, casting an eerie glow. The color palette is dominated by deep indigos, charcoal grays, and touches of muted silver for the lightning and castle highlights. The overall mood is suspenseful, mysterious, and slightly ominous, hinting at secrets and danger. The composition is centered on the castle, with the stormy sky filling the upper two-thirds, creating a sense of scale and isolation. The aesthetic should be professional and visually striking, suitable for a thriller or mystery genre. Square 1024x1024 format, no text.",
