A square, 1024x1024, professional audiobook cover art. The image should evoke a sense of nostalgic, magical realism set in rural Eastern Europe during the interwar period. Dominant imagery features a majestic, ethereal stag with luminous, soft blue antlers, appearing as if formed from moonlight or mist. The stag is set against a backdrop of rolling, dewy hills at dawn, shrouded in a gentle, atmospheric mist. Subtle elements of traditional, slightly weathered wooden fences and distant, softly lit, humble farmhouses can be glimpsed through the fog. The color palette is subdued and rich, featuring deep emerald greens for the landscape, soft greys and whites for the mist and stag's antlers, and warm, muted ochre or golden hues for the distant light sources. The overall mood is serene, contemplative, and tinged with a touch of mystery and enchantment. The composition should be balanced, with the stag as the clear focal point, drawing the viewer into the scene. The lighting is soft and diffused, with a subtle glow emanating from the stag's antlers. The style should be painterly, with visible brushstroke textures suggesting oil on canvas or a rich digital painting, conveying depth and emotion without any photographic realism. Absolutely no text, letters, or logos.
