  "prompt": "A square, 1024x1024 professional audiobook cover art. The image depicts a dramatic scene with a powerful, ethereal glow emanating from a swirling vortex of deep indigo and amethyst colors. Within the vortex, faint, intricate patterns resembling ancient runes or constellations are subtly visible. Tendrils of shadowy, dark violet mist curl outwards, hinting at unseen forces. Silhouetted against the glow, a single, ancient, gnarled tree with branches reaching like grasping fingers is partially visible on a rugged, dark terrain. The overall mood is mysterious, magical, and slightly ominous, with a color palette dominated by deep blues, purples, and blacks, accented by the luminous glow. The lighting is dramatic, casting long, soft shadows. The composition is balanced, drawing the eye towards the central vortex. There is absolutely no text, letters, or logos present.",
