Known Vanduul territory consists of 16 planetary systems, with jump point connections to multiple points in the United Empire of Earth (UEE). The Caliban, Orion, Tiber, and Virgil systems were formerly controlled by the UEE, but were lost to the Vanduul after massed invasions. No permanent Vanduul settlements have been observed on any planet in Vanduul Territory. It is theorized that the Vanduul use celestial bodies purely for resource gathering. Newly discovered systems that have a significant Vanduul presence are given a military designation VS and a code name starting with the letter “V” such as the Vanguard system and the Voodoo system.
