Croshaw I is a terrestrial planet with a thick, high pressure-atmosphere that closely orbits the star of the Croshaw system. After its discovery in 2271, some prospectors attempted to establish harvesters on the planet's surface in an effort to gain easy access to industrial-strength acids. However, the vivid yellow and orange atmosphere proved too corrosive for even the most advanced technology at the time to effectively harvest.
