Mevinna was a Class M planet located in the space of the galaxy's Alpha or Beta Quadrants. It had three moons and no native humanoid life. Land comprised one-sixth of the planet's surface, and most of the land was covered with forest. It contained many rare minerals, including verilium and obsitrate, and was particularly rich in pyretimite. It was inhabited by scattered small colonies of various races.
