A spaceport existed on the planet Primea, situated inside the Vak Combine nation within the Unknown Regions. During 19 BBY, Chiss Senior Captain Mitth'raw'nuruodo, whose core name was "Thrawn," along with Caregiver Mitth'ali'astov "Thalias," journeyed to the spaceport with the intention of covertly departing the planet. After entering the spaceport, they employed tava gas to disable the personnel of a patrol boat and commandeered the vessel; subsequently, they were rescued by Thrawn's superior officer, Admiral Ar'alani.
This spaceport was featured in the 2020 novel Thrawn Ascendancy: Chaos Rising, which marks the initial book in Timothy Zahn's Star Wars: The Ascendancy Trilogy.
