  "prompt": "A square, professional audiobook cover art with a dark, brooding, and atmospheric mood. The primary visual is a silhouette of a lone, determined figure standing on a windswept, desolate moor under a stormy, twilight sky. In the distance, partially obscured by fog and shadow, are the stark, angular outlines of a large, old, isolated manor house. Subtle, almost imperceptible, hints of tangled, thorny vines weave around the edges of the composition, symbolizing hidden dangers and a sense of entrapment. The color palette is dominated by deep, desaturated blues, grays, and blacks, with a very subtle, cold, almost unnatural hint of pale moonlight breaking through the clouds. The overall impression is one of mystery, danger, and a deep, unsettling psychological tension. High contrast, cinematic lighting, and a sharp focus on the central elements. 1024x1024 format. No text, no letters, no words.",
