Neptune is a planet in the solar system. Approximately 4 billion years ago the Dortheans called it 10. It was then lifeless, at the time, but the Dortheans terraformed and colonised the planet. There were two colonies of the Dortheans on Neptune, North10 and South-10. An unestimatable amount of time later and the planet was dead again. However in the year 2574 humans from Earth started terraforming it. Some time after it was finished terraformed, in the year 5430 a colonisation team consisting of the Earth Greater Empire, the United States Of South America, and South Finland, colonised Neptune.
