At some point, Stai joined the Galactic Union. Stai was politically surrounded by staunch Union-allied planets.
In 2266, the Federation starship USS Enterprise orbited Stai. After Captain James T. Kirk rescued Stai children held on Vrex, Staians formally quit the Union and demanded that their soldiers leave. (TOS comic: "The Children of Stai")
