The Expansionary Defense Fleet headquarters is situated on the Unknown Regions planet Naporar, serving as the central base of operations for the Chiss Expansionary Defense Fleet.
Before Ba'kif's elevation to Supreme General of the Chiss Defense Force, he directly oversaw the Chiss Expansionary Defense Fleet, operating from his office within this headquarters as a General.
The presentation of credentials at the headquarters is a requirement in the ceremony for one to become a Patriarch. Around 118 BBY, the Patriarch was required to present these credentials themselves, but by 18 BBY, an aide was permitted to deliver them. In 18 BBY, Thivik journeyed to the headquarters to submit Thurfian's credentials for his position as Patriarch.
