The Global Exodus Alliance (or GEA) was an organization formed to oversee the evacuation of Earth. To this end, they were ultimately given the power to govern the planet and replacing the World Economic Consortium as the primary political body of the planet. The GEA was primarily funded through combined efforts of China and the United States of America, allowing them to become the most powerful national entities.
The GEA's rule was brutal for the people of Earth, causing a steep decline in the population. They declared planet-wide martial law and maintained order with an iron fist. Ultimately, however, they were able to save a vast majority of the population -- leaving just over the 5% of the population projected to be able to survive on the planet.
The Global Exodus Alliance is derived from Firefly.
