Phannis System

The Phannis System is a star system in the Orion Arm of the Milky Way Galaxy consisting of five planets orbiting a A3V main-sequence "bluish-white" dwarf. One notable feature of this system is that it serves as the home system for the Staalzi alien race. However, currently, it is under the control of the Hivivian Empire, a technocracy hegemony comprising several alien species.
