Arcona Citadel

From Wikipedia of the Dark Brotherhood, an online Star Wars Club

The Citadel serves as the headquarters and base of operations for Clan Arcona in Estle City on Selen, residing in the Dajorra system.

The ‘Citadel’ is more of a tower and is set back from the lip of the plateau, with a large open area perfect for the various ceremonies undertaken by Arcona and its leader. Forward of this is a long causeway that grants a panoramic view of the surrounding countryside.
