  "prompt": "A square, atmospheric digital painting for a book cover. The style is a blend of photorealism and dramatic chiaroscuro, evoking a sense of ancient mystery and urgent discovery. The central imagery features an intricately carved stone artifact, glowing faintly from within with a soft, ethereal blue light. This artifact is partially unearthed from dark, rich soil, hinting at a hidden excavation site. Surrounding the artifact are scattered, ancient parchment fragments, some with faded, cryptic symbols that appear to be partially illuminated by the artifact's glow. The overall color palette is dominated by deep earthy browns, blacks, and rich ochres, contrasted by the cool, luminous blue emanating from the artifact. The composition is centered on the artifact, with elements leading the eye inward, creating a feeling of depth and intrigue. The mood is suspenseful, intellectual, and slightly foreboding. Think of the visual aesthetic of Indiana Jones combined with the artistic direction of Dan Brown's book covers, but rendered with a painterly, atmospheric quality. The aspect ratio is 1:1, suitable for a square audiobook cover. Absolutely no text, letters, words, title, or author name should be present in the image.",
