Planet Xyleria, visible from space as a swirl of vibrant azure and emerald hues, is wrapped in a thick, translucent atmosphere dotted with shimmering reflections suggestive of airborne crystals. This exoplanet, slightly larger than Earth, exists in a state of perpetual twilight due to its dense, reflective cloud cover which diffuses the light of its nearby star. The surface of Xyleria is dominated by vast rainforests composed not of organic foliage, but of towering crystalline structures resembling trees, their surfaces faceted like diamonds. These forests scatter the starlight into spectacular, luminous displays, creating a landscape that sparkles ceaselessly. The unique meteorological phenomenon on Xyleria involves periodic rains of small, diamond-like crystals, which replenish the forest's growth and contribute to the planet’s reflective quality. These rains, capturing and refracting light, create a dynamic, ever-changing surface spectacle of radiant, natural light shows.
