(OOC)My inner geek compels me to correct you. The Rule of One was reinstated some time after Darth Bane's death when some Sith Lord (the name escapes me at the moment) decided that the Sith Empire's time had come yet again. He interpretted the rule as the Sith as One Body, devoted to a singular cause, to serve the Dark Lord.
EDIT: Darth Krayt (/OOC)
(IC)Good luck Ivan
