It was a twelve-member council consisting of powerful Sith Lords that obeyed the Sith Emperor, their Dark Lord. After the Treaty of Coruscant and the conclusion of the Great Galactic War, the Emperor withdrew to pursue his own mysterious goals, deferring power over the Empire to the Dark Council. The Dark Council then oversaw the consolidation of the Empire's new domains.
