A system of 4 stars, one giant class G star, and 3 class M planets circling around it. Each of the class M stars have several planets, but only two are habitable. One spawned life.
The only planet of the four stars that spawned life, and one of only two that can sustain most life forms. This is where the Raginors came from and spread out into the galaxy. They started by colonizing their second planet, then they terraformed the others to be livable. Their terraforming techniques did not last, however their ruins can be found on most of the planets in all of the systems, as well as their extraordinary terraforming techniques and some skills at genetic modifications.
