  "prompt": "A dramatic, evocative digital painting suitable for a historical fiction audiobook cover. The scene depicts a dark, ornate castle interior, possibly a royal chamber, illuminated by flickering candlelight. Shadows are deep and cast long, distorted shapes across stone walls and heavy tapestries. In the foreground, subtly rendered, a single, ornate dagger lies on a velvet cushion, its hilt glinting faintly. The overall mood is one of suspense, danger, and impending doom, with a rich, muted color palette of deep reds, burgundies, ochres, and shadowy greys. The composition should be balanced and professional, with a central focus on the atmosphere and implied narrative. Square 1024x1024 format. No text, no letters, no words, no title, no author name.",
