  "prompt": "A minimalist, atmospheric, and slightly surreal audiobook cover art. The scene depicts a desolate, snow-covered mountain pass at twilight. In the foreground, a single, gnarled, skeletal-looking tree stands as a solitary sentinel. Behind it, a vast, imposing, and starkly angular fortress-like structure is partially obscured by swirling, ethereal mist and the deepening gloom of dusk. The overall mood is one of profound isolation, anticipation, and encroaching, unseen threat. The color palette is dominated by deep indigos, muted greys, icy blues, and hints of pale, fading ochre in the sky. The composition should evoke a sense of vastness and vulnerability, with the fortress appearing both protective and ominous. The style should be painterly and textured, with a sense of depth and shadow, suitable for a classic literary work. Square 1024x1024 format. NO text, NO letters, NO words, NO title, NO author name.",
