  "prompt": "A stylized, dramatic book cover art, square format 1024x1024. The central imagery is a partially obscured, ancient stone obelisk, casting a long, sharp shadow across a stylized, geometric floor reminiscent of a secret society's chamber. Subtle, ethereal light emanates from around the top of the obelisk, suggesting hidden knowledge. The color palette is dominated by deep blues, midnight purples, and a contrasting, warm golden light, creating a mood of mystery, ancient secrets, and urban exploration. The overall aesthetic is professional, slightly gritty, and evokes a sense of intellectual pursuit mixed with palpable danger, suitable for a conspiracy thriller audiobook cover. No text, no letters, no words, no title, no author name.",
