A square, 1024x1024 aspect ratio, professional audiobook cover art. The scene is a vast, sun-drenched African savanna at dawn. In the foreground, a lone, gnarled acacia tree stands silhouetted against the sky, its branches reaching out like ancient hands. Golden light filters through the sparse leaves, casting long, dramatic shadows. In the middle distance, a herd of wildebeest is caught in a graceful, slow-motion stampede, their forms softened by the morning mist rising from the plains. The background features distant, hazy mountains painted in muted purples and blues, and a sky transitioning from deep indigo to soft rose and warm ochre. The overall mood is one of immense scale, quiet majesty, and a touch of gentle melancholy. The visual style should be painterly, with rich textures and atmospheric lighting, evoking a sense of timelessness and raw natural beauty. No text, no letters, no words, no title, no author name.
