Planet Ethyria, a stunning orb viewed from orbit, dazzles with a turquoise glow—an iconic feature of its expansive hydrogen-helium atmosphere. Ethyria is slightly smaller than Earth, characterized by its brilliant, sunlit diamond sea islands scattered across a dominantly aquatic surface. The islands reflect an array of shimmering light, appearing as crystals floated atop azure waters. The diverse topography includes fine, sand-like diamond granules that form majestic dunes, modifying their shapes under the gentle influence of mild, silken breezes. The atmosphere is laced with helium, lending an ethereal quality to its luminous skies. The unique weather system on Ethyria fosters a serene climate with occasional radiant storms, where electrified particles ignite fleeting, scintillating skies above the islands. This dance of elements, combined with the radiant ocean, makes Ethyria a celestial marvel from both afar and upon closer scrutiny.
