The Imperial Citadel was the structure the surviving Sith relocated to following the Great Hyperspace War. They were led there by the individual that would become the Sith Emperor.

Within the Sith's first century of their retreat to Dromund Kaas they constructed Kaas City deep in the jungle, a testament to reestablishing the grand Imperial society lost in the Great Hyperspace War, and a mighty citadel in the center of the city which was known to house the Emperor and his Dark Council.

As the center of Imperial government, the citadel contained the headquarters of the Ministries of War, Intelligence, and Logistics. The citadel was also home to a Mandalorian embassy of sorts, known as the Mandalorian enclave.


The Imperial Citadel on Dromund Kaas had two separate incarnations. The first one built on the planet resembled both the Sith Academy on Korriban and the Sith Citadel on Ziost. This was destroyed in 4043 BBY during the Kaggath fought between Darth Qalar and Darth Victun. The two Sith Lords were executed by the Dark Council, and Darth Nostrem was chosen to oversee the citadel's reconstruction.

The second citadel was designed by the Sith Emperor himself and differed greatly from the first. It was no longer modeled after the earlier citadel designs. After its construction, Darth Nostrem was locked in its depths in order to test the citadel's new labyrinthine defenses. The Sith Lord never escaped and eventually died.
