  "prompt": "A square 1024x1024 digital painting in a style reminiscent of classic European fantasy illustration, evoking a sense of mystery and ancient power. The image depicts a stark, rocky mountain landscape at twilight. In the foreground, a gnarled, ancient oak tree with twisted branches dominates, its silhouette sharp against the dimming sky. Emerging from behind the tree, or perhaps within its shadow, is a subtle, ethereal luminescence that hints at a hidden, otherworldly presence – not overtly monstrous, but suggesting a powerful, ancient spirit or guardian. A sense of deep, silent history pervades the scene. The color palette is dominated by deep blues, purples, and dark greys for the mountains and sky, with touches of ethereal, soft silver-blue or pale gold light emanating from the mystical element. The mood is solemn, evocative, and slightly melancholic, hinting at untold stories and a wild, untamed nature. The composition should be balanced and draw the viewer's eye into the mystery, with the tree acting as a natural framing element. Professional audiobook cover aesthetic.",
