sean

sean presents as cobalt blue, with a world-spanning sea over a hidden rocky floor, with three moons in various orbital configurations. A single broad ring of irregular silicate debris extends from just outside the Roche limit, with a sharp outer edge suggesting gravitational confinement. A smaller sibling world shares its sky, near enough to show a visible disc. Surface temperatures range from 10 to 95°C at 1.1 atm, with temperature inversions that create mirror-still surface zones. At 12,407 km across, the surface material is primarily liquid water or ammonia ocean over a silicate seafloor. The ocean here represents an extraordinary volume of liquid — enough to cover an Earth-sized body to a depth of hundreds of kilometres.
