静かな夜の湖の上に輝く古代の世界樹

A vast nocturnal dreamscape beneath an endless cathedral of stars. A colossal ancient World Tree rises from the edge of a perfectly still lake, its roots disappearing into dark water and weathered stone. Soft golden light glows from deep within the trunk, illuminating twisted bark and drifting particles like ancient memories. Delicate rings of luminous energy surround the tree, resembling forgotten celestial geometry. In the foreground, a solitary cloaked figure sits in silent meditation on an ancient circular stone platform engraved with subtle sacred patterns. The water reflects the immense tree and the infinite night sky like polished obsidian. Fine mist drifts across the lake while faint beams of moonlight dissolve into the darkness. The atmosphere feels ancient, quiet, and sacred rather than dramatic. Invisible forces seem to move through the air; dust slowly rises from the ground as if gravity itself has softened. The landscape breathes with deep resonance, suggesting forgotten wisdom, memory, and timeless order. Massive mountains fade into blue-black darkness beneath an immense cosmic sky filled with countless stars and faint galaxies.
