Been thinking on what sort of faction the Gaia Reclamation Initiative would be, and one potential outcome is a sort of AI project by either a private organization or one of the power blocs of the late 21st century. The AI made with the purpose of helping and direction restoration efforts of the world if things truly got dire. There are some blanks in between, but at some point, the AI would go full Skynet/Ultron on its creators, seeing machines as better stewards of the Earth. It probably be based in Antarctica. 

That's the first draft so far, may change at some point of course, may even turn into something completely different XD.
