Crystalline Star City

A celestial city composed of crystalline structures that catch and refract light, creating a dazzling display of rainbows across the skyline. The buildings are tall and slender, with spire-like tops that reach towards the stars. The city is enveloped in a nebula of swirling colors, giving the impression of floating in space. A shimmering river of stardust winds through the city, adding to the celestial theme. The ethereal glow and futuristic design elements convey a sense of mystery and cosmic beauty.
