Rule of One

The Rule of One was the guiding principle of the Sith in the internecine New Sith Order.

When Darth Krayt founded his new Sith Order, he abolished the Darth Bane's Rule of Two, dicate which commands that there could be only two Sith at any one time, master and apprentice. Instead, there would be the Rule of One&mdash;that One being the Sith Order itself, under which there would be many Sith.
