Ectidarvo

Ectidarvo, or Ectidarvo b, is a scorching carbon/diamond world in a star system of the same name near Romoni. It orbits within the thin upper atmosphere of its red giant star, making the system appear to have only three planets instead of four.
==Surface==
Ectidarvo's shallow surface is comprised of graphite "soil" mixed with smaller amounts of other minerals, such as iron, silver, tin, and metalloids. A few hundred feet beneath the surface is a solid interior of diamond. The crust also features vents that spew carbon monoxide.
==Fauna==
The only known life on Ectidarvo are the iron-based carbon worms, which are colossal organisms that were recently discovered by the crew of the Cleesha on a mining expedition to the searing world. Typically hundreds of feet long and possessing rows of huge sharp teeth, the worms burrow vast cave networks throughout the planet, leaving behind shimmering trails of diamond dust. They had also apparently been subjected to Ra-Shi experimentation prior to the official end of the Ra-Shi War, displaying railgun mounts and tractor beam emitters of Ra-Shi design which they used to attack the Cleesha. They allegedly consume the native minerals in the soil.
==History==
The system had long been rumored to have an entire planet made out of diamond, though no proof had been seen. Ectidarvo was discovered sometime around 2200 by early astronomers of a long-dead race, charted prior to its star becoming a red giant. Frank Croskey, captain of the Cleesha, was in possession of an old stone tablet that displayed an ancient star map that their people had used to chart the stars. Their technology was ahead of their time, though they couldn't see the meteor headed for their planet and were rendered extinct as a result. According to Frank, this surviving artifact took "three painstaking months to translate" and served as proof that such a planet existed in that system.
