Luna

Luna is a celestial body orbiting Earth, and is Earth's only natural satellite. In 1969, humanity first landed on Luna, then known just as the Moon. However humans didn't establish a permanent presence on the body until 2091. In 2123 the Somakians discovered the Sol system via a randomly appeared wormhole. The colonists on Luna were among the first casualties of the Survival War once the Somakians discovered of humanity's existence. After the war humans established another colony on Luna, which they named 'Luna City'.
