Timeline

2162

Armed conflict ripped through South America, as Koslovic, Frieden and UN forces clashed over ideological differences, sparking additional conflicts off-planet, such as the Argyre Planitia Campaign. This war brought a great deal of suffering to the people of Earth, and caused an enormous famine.

2170

In the post-war period, there were massive population surges, resulting in overpopulation. Coupled with the destruction and famine bred by the Rain Forest Wars, the economy threatened to destabilize.
