Amidst a cluster of fantastical islands floating in space, connected by a colossal rainbow bridge, a giant and slender multicolored divine dragon, its immensely long, serpentine body like a living rainbow, gracefully extends between two islands, transforming into a bridge of pure light. Its scales are translucent, capable of capturing and scattering all spectrums of cosmic light. Each scale refracts flowing and shifting iridescent colors, and as it moves, it leaves a trail of flowing aurora behind it. Its long whiskers are pure, constantly changing bands of light. The dragon's head is lowered, its eyes filled with guiding wisdom, gazing down at the tiny travelers passing over its body.
