The entire Capital Star region of the Galactic Federation is vast, encompassing three nearby planetary systems. Although these three systems aren't as expansive as the Solar System, the closest distance between them is over a light year, and the furthest is about 2.2 light years. These three systems form a triangle, and the entire Capital Star region consists of nine administrative stars, or nine inhabitable planets.
These nine planets have clearly been transformed through the tremendous efforts of the Galactic Federation. It seems that they have all been modified by the source of life. Although each one has its distinct scenery, all are quite extraordinary.
