Here in the Milky Way Galaxy, nearly all the Humans are members of the Galactic Federation of Worlds.
It is mostly an alliance of Humans, but there are some non Human members too. And there is an alliance with the "Annunaki" (the Annok Empire).
Right now the GFW is the most powerful force in the Galaxy.
The Universe is a very dangerous place, and there is safety in having powerful Frens.
