Sith ' ari Sith ' ari was a title that , in the ancient Sith , meant " Lord " or " Overlord , " first claimed by King Adas . After Adas ' s death , the term became the subject of a legend prophesying the coming of a being that would lead and destroy the Sith , but in doing so would make the Sith more powerful than ever before . In this context , the term came to mean " perfect being " or " god . " The prophecy , which was in many ways similar to the Jedi prophecy of the Chosen One , retained its significance for the Dark Lords up until the time of the Order of the Sith . The Sith ' ari Prophecy . The Sith ' ari Prophecy was considered too sacred to be put into writing by the Kissai , who passed it on verbally from generation to generation . Sorzus Syn recorded it thus c . 6900 BBY : < poem > " The Sith ' ari will be free of limits . " " The Sith ' ari will lead the Sith and destroy them . " " The Sith ' ari will raise the Sith from death and make them stronger than before . " < / poem > The legend . Sometime during the early history of the First Sith Empire , the coming of the " Sith ' ari " was foretold . Inspired by the legend of Adas , the Sith ' ari , referred to sometimes as " the prophesied one , " was to be a perfect being , free of all restrictions — the ultimate Sith . The Sith ' ari would rise to power to lead the Sith and , according to the legend , destroy them — yet , through their destruction , make them stronger than ever . Some of the students at the academy on Korriban thought Sirak was the Sith ' ari . However , Sirak was killed by his nemesis , Bane . Darth Bane , eventually becoming a Dark Lord of the Sith , finally fulfilled the prophecy in many ways , first by providing Skere Kaan with the thought bomb , which caused the annihilation of the Brotherhood of Darkness , and then by instating the Rule of Two , leading to a powerful line of Sith by reducing their numbers to only two at a time . This allowed the dark side to distill in two vessels only ; whereas Bane believed that its power in the past had been spread far too thin among the vast numbers of Sith ' lords ' . This concentration of strength also made it easier to hide the Sith until they built up enough power to destroy the Jedi , and thereby open the way for the Sith to rule the galaxy . Although Darth Plagueis , due to being a creature of logic and not superstition , never believed in the " Sith ' ari " prophecy , or any prophecy since he considered prophecies " wishful thinking " , he nonetheless saw no reason to not claim the title figuring that it ultimately fit him . Almost a millennium later , Darth Sidious proclaimed himself to be the perfect being of ancient Sith prophecy while killing his master , Darth Plagueis , in his sleep . Behind the scenes . Ever since its first mention , fans have speculated who the Sith ' ari was . Some of the most notable candidates among this speculation were Darth Revan , Darth Bane , Darth Sidious , and Darth Vader . " The Complete Star Wars Encyclopedia " , however , establishes Bane as being the looked - for Sith ' ari , confirming the assumptions of many fans . But the title has also been interpreted as having multiple holders throughout galactic history . Giving credence to this , the 2012 publication " " featured a number of references to the prophecy of the Sith ' ari in what was intended by the book ' s author , Daniel Wallace , to be a running joke , whereby each in - universe writer of the " Book of Sith " came to the conclusion that he or she was the Sith ' ari .
