The Pandora orbital resort was originally constructed as a cargo transfer and storage point for Kaperth's lunar terraforming project.
Once the project was completed, however, Pandora quickly became a tourist attraction and with the tourism, came the need for resident workers. Soon, a large mall, restaraunts, and plush living areas were constructed within its walls and even an "outdoor plaza", on the outer main plate of the station, having an atmosphere contained by a thin energy barrier over the top.
Pandora is also an easy target for Zetsfir attacks, since it is far away from Fumacine's main defense systems and relatively isolated. Because of this, Fumacine has stationed several of it's own personnel at Pandora, including the three elite Fumacites at the beginning of chapter two.
