Kaan
this Sith Lord was one of the few Sith who survived the internal violence which tore the Sith order apart, some 2,000 years before the Battle of Yavin. Lord Kaan gathered some twenty thousand Sith devotees and set out to take control of the galaxy. He made his stand against the Jedi on the planet Ruusan, where he was opposed by the Jedi Master, Lord Hoth, and his Army of Light. Lord Kaan's tactics of fighting the Jedi in individual battles did not sit well with many other of the Sith Lords, especially Darth Bane, who believed that the Sith had to unite in the Dark Side of the Force in order to defeat the Jedi. It was rumored that Kaan even tried to poison Darth Bane, on an effort to eliminate any opposition to his command. Lord Kaan and his followers planned to unleash a thought bomb on the planet Ruusan, where the two sides had been fighting. Lord Kaan, and virtually every warrior in the battle, was obliterated when the thought bomb was set off. In the wake of the Battle of Ruusan, Kaan's so-called Rule of the Strong was abandoned by Darth Bane, who instituted the Rule of Two in order to ensure that the Sith could survive.
