A fluorescent space city floats silently in the infinite dark, a dazzling beacon among the stars. Suspended within a vast gravitational bubble, the city gleams with vibrant neon hues—pulsing pinks, electric blues, radiant greens, and ultraviolet violets—casting soft glows across the void. Towering spires made of translucent alloys shimmer like crystal stalagmites, their surfaces alive with flowing light patterns that respond to unseen rhythms.
