静かな夜の湖畔に輝く古代の世界樹

A vast nocturnal dreamscape beneath an endless star-filled sky. A colossal ancient World Tree stands beside a perfectly still lake, its twisted roots disappearing into dark water and weathered stone. A soft golden light glows from within the trunk, illuminating drifting dust and fine mist like ancient memories. In the foreground, a solitary hooded figure meditates on a circular stone platform. The water reflects the immense tree and the infinite cosmos. Blue-black mountains fade into darkness while invisible energy seems to move through the air. Sacred, timeless, mysterious atmosphere, deep silence, photorealistic dark fantasy, mystical realism, volumetric moonlight, cinematic lighting, atmospheric fog, ultra-detailed bark and stone, deep depth, HDR, 8K, masterpiece.
