- "I've been there. Very gloomy place. Unnecessarily so."
The Sith Citadel, known to the resurgent Sith Empire as the Great Citadel was a fortress built by the Sith Empire on Ziost sometime before the Great Hyperspace War. It served as their capital and the meeting place 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 visited this citadel with Kiara Olvidan while looking for the Amulet of Kalara.
