Although humanity has spread across the solar system, the humans of Ganymede continue to be proud that their small moon is their race's birthplace. Although Earth now supports a larger human population than Ganymede does, nowhere in the solar system is the human race closer to the Legion of Terra's vision.
Under King Olaf Sigvidsson, the humans of Ganymede practiced fair trade with all powers in the solar system, even their primary competitors, the grays of Io. With war brewing among the inner planets, the aging Sigvidsson was not able to keep up with events, and business suffered as a result.
Ganymede features the system's largest rocket fuel harvesting infrastructure. Now, Ganymede functions as a fuel source for the Axis of Evil.
