Ars 1138 was the seventh and smallest planet in the Kobbane system, roughly the size of the first Death Star. Due to its having no natural form of gravity, Ars 1138 had only one city, Terminal 1. The city was completely encased in transparisteel and was home to a sizable population of scientists and researchers. The entire 20 km² complex was housed safely within the perimeter of two overlapping forcefields, providing safety to the inhabitants and trillions of credits worth of research in case of an attack. It also served to protect the base against the meteor showers that happened occasionally
