Fehl Prime is one of the top producers of pharmaceuticals for the Systems Alliance, making its defense a high priority for the Alliance military. A habitable planet with at least 3 moons, Fehl Prime's colony proper is established in an arid, desert-like region, but other areas feature extensive native flora that include massive, bio-luminescent, fungus-like growths. The planet is also the site of an intact and functional Prothean interstellar communication device believed to be at least 70,000 years old, although as of 2185 it is not being actively studied.
