虹色に照らされた水晶洞窟に浮かぶエーテルの妖精

A crystal cave where every surface refracts and reflects the light of a hidden geode. Rainbows arc and dance across the cavern walls, bouncing off facets of amethyst and quartz. A single, ethereal sprite with translucent wings hovers in the center, catching the prismatic light. The style is luminous fantasy art, with hyperrealistic textures on the crystals, emphasizing the vibrant, light-bending reflections.
