Creterious

Creterious is just a very large meteor that isn't inhabited by anything, there is a rest station, a hotel, a restaurant. It is mainly used as a rest stop for inter-galactic travel. The only "inhabitants" are the people who work at the rest stop, they live at Quadronos, the nearest planet. This is what people think. What is really happening is that Creterious happens to be the base of the APT, they hollowed out the inside of the meteor to have room for their base.
