Eayn is the home planet of the Kig-Yar, or Jackals/Skirmishers. The gravity is about 0.875 G's, making the inhabitants lighter on Eayn than on Earth. This is surprising, considering how swiftly Jackals can move on Earth. Eayn's atmosphere is composed of oxygen, nitrogen, and carbon dioxide (Rather similar to Earth). It contains a surface temperature ranging from -18°C to 45°C (-0.4F to 113F). It could be presumed that the satellite is extremely similar to Earth.
