The year is 5542, twenty years after the United Federation arrived at Pandora. Tensions have been rising between the United Federation and The Confederacy of Pandora, after they splintered off in 5534. The planet itself is inhabited by strange hostile creatures, and no known species can breathe the air, other than those creatures. Because of this, both the United Federation and The Confederacy of Pandora have constructed cities protected by atmospheric shields, which provide some protection against multiple forms of attack, but cannot take heavy fire. There are aincent structures left behind by a mysterious civilisation, containing technology more advanced than anything anyone has seen before. The Confederacy of Pandora wants to use this technology for themselves, and the United Federation is not so sure about this and believes that the technology should be left alone, at least for now.
