黄金に輝く雲海の上に浮かぶ壮麗な大理石の街

The Floating Citadel: "A majestic white marble city floating among golden clouds at sunset. Waterfalls cascade from the islands into the mist below. Sunlight filtering through grand arches, vibrant pastel palette, dreamlike surrealism, in the style of Studio Ghibli but with hyper-realistic textures."
