Gaia
In a star system at the edge of Ur-Quan space closest to Earth lies Gaia, home to the Syreen. Formally Betelgeuse I, it was given to the Syreen as a suitable planet in which to be slave-shielded after their defeat at the hands of the Ur-Quan Hierarchy.
Gaia is the first planet in the Betelgeuse system, which can be found at HyperSpace coordinates 412.5 : 377.0.
It is a Water World. It is orbited by a Star Base commanded by Talana.
