  "prompt": "A square 1024x1024 image for an audiobook cover. The visual style is dark fantasy, mystical, and slightly surreal. The central image is a stylized, ornate key, crafted from obsidian or dark, polished metal, casting long, dramatic shadows. The key's teeth are subtly shaped like ancient, forgotten symbols or glyphs. Behind the key, a swirling vortex of deep indigo, amethyst, and hints of emerald green, reminiscent of a cosmic nebula or a portal to another dimension. Faint, ethereal light emanates from within the vortex, suggesting hidden knowledge or a hidden world. The overall mood is mysterious, intriguing, and invites curiosity. The composition is balanced with the key as the focal point, drawing the viewer's eye into the vortex. The atmosphere is one of ancient secrets and profound exploration. No text, no letters, no words, no title, no author name.",
