The Order of the Sith Lords, also known as Bane’s Sith Order, Banite Sith, or simply the Sith, was an ancient organization of Force-sensitives who utilized the dark side of the Force. Founded approximately one thousand years before the Battle of Yavin by the Sith Lord Darth Bane, it was intended to replace the Brotherhood of Darkness and institute a rebirth of the Sith. The guiding principle of the Order was the Rule of Two, which was developed by Bane through the teachings of DarthRevan‘s Holocron. Under this new tenet, only two Sith Lords were allowed to exist at any given time; a master and an apprentice. The Rule stipulated that after learning everything the master had to teach, the apprentice would attempt to kill the master and take an apprentice of their own. The intended effect of this rule was to ensure that each successive master would be stronger than the last. Ultimately, Bane intended that his successors would be able to amass enough power in secret to engineer the fall of the Republic and the destruction of the Jedi Order.
