- "I've been there. Very gloomy place. Unnecessarily so."
The Sith Citadel was a fortress built by the Sith Empire on Ziost. It served as their capital and the meetingplace of the Sith Council.
Millennia later, Lumiya would visit it some time before the Second Galactic Civil War (possibly while building her lightwhip on Ziost in 4 ABY). Jacen Solo may also have visited it before then. Ben Skywalker possibly visited this citadel with Kiara while looking for the Amulet of Kalara.
