Pi'tua (La'uo I)

Pi'tua (La'uo I) is the first planet from the sun of the La'uo system, Xi'an Empire (SaoXy'an). A chthonic planet, it was the core of a hot Jupiter until the surface of the red giant it orbits expanded. Most of its atmosphere has evaporated, and what little remains continues to sublimate away in the heat. This has created a comet-like streak of gas and dust that trails the planet on its journey around its sun.
