Each Sith Lord or Lady had their own specialty and unique connection with the Force, and all of them were feared (and sometimes revered) in different ways. There have been many Sith Lords and Ladies since the Order’s creation, and they all mastered incredibly powerful Force techniques. This way, conflicts between Sith were largely prevented, and the Sith lineage lived on. There must only be two, the Master, and the apprentice. Because the Sith were, by nature, violent and bloodthirsty, Darth Bane created the Sith Rule of Two to preserve the Order. Sith value strength and power, and most will go to great lengths to obtain it. The Sith Code taught its followers that “peace is a lie, there is only passion,” which makes it a direct counterpart to the Jedi Code.
An ancient Order with its own code and philosophies, the Sith Order has counted numerous members over the years. In the Star Wars universe, the Dark Lords and Ladies of the Sith were a source of both terror and fascination.
