The Saiax Confederacy is an organization led by the Saiax that was founded in 4263 BCE.
The organization was founded after they developed technologies for interstellar missions. The Saiax believed an organization needed to be created in order to limit what can be done within the range of their Warp Drives and Wormhole Drives. For thousands of years, the confederacy had suffered many conflicts and even wars.
It came to an end during the First Galactic War when the galactic population of Saiax had dropped by 5 billion, reducing the galactic population to about 230 billion.
