  "prompt": "A dramatic, atmospheric digital painting suitable for an audiobook cover. The central image features a stylized, ancient-looking keyhole, partially obscured by swirling, shadowy mist. Through the keyhole, a faint, ethereal light emanates, hinting at a hidden world or profound secret. The color palette is dominated by deep, moody blues, rich purples, and hints of aged gold or bronze around the keyhole and the mist. There's a sense of mystery, discovery, and ancient knowledge. The composition is centered and focused, creating a feeling of intrigue and depth. The overall aesthetic is sophisticated, dark, and evocative, with a professional, high-quality finish. Square 1024x1024 format. No text, no letters, no words, no title, no author name.",
