however, Bane realizes that the trap is actually meant for Sirak. Githany kills Sirak's henchmen, and Bane defeats and kills his old nemesis in a lightsaber duel. Bane takes the long-abandoned Sith title of Darth, leaves the Brotherhood, and travels to Rakata Prime. There, he discovers a Sith Holocron left behind by Darth Revan. Bane completes his training, learning numerous Sith techniques, including the "thought bomb" designed to kill all Force-sensitive beings in reach. He sends this to Lord Kaan. Bane then devises the "Rule of Two": only two Sith Lords, a master and an apprentice, are allowed to exist at one time ("One to embody power and one to crave it.") Kaan orders that all of the students on Korriban be made into Lords and brought to battle on Ruusan. Kaan sends Kas'im to bring Bane back to Ruusan to join the Brotherhood on pain of death. Upon meeting his former teacher, Bane considers taking him as an apprentice, but ultimately kills him after being refused. Afterwards, Bane takes it upon himself to destroy the remaining Sith and take on an apprentice to carry on the Sith legacy after him. Bane sends a staged message to Kaan asking to join the Brotherhood; Githany volunteers to kill Bane. Unknown to Githany, Bane had also sent the thought bomb, supposedly as a token of goodwill. Githany finds Bane, and pretends to accept his offer to join the Brotherhood. Githany slipped him poison in a kiss, and he is rendered violently ill. Barely alive, Bane eventually finds a healer named Caleb and extorts his help by threatening his daughter. Caleb cures Bane of the poison and nurses him back to health. Bane returns to Ruusan, where Kaan agrees to follow his lead in battle. During meditation, Bane uses his own body and power as a focusing agent to unleash a wave of destruction upon the forests of Ruusan, where the Jedi's Army of Light is hiding. When the other Sith Lords mutiny, Bane orders the commander of the space forces to engage the Jedi fleet. Realizing he is facing defeat, Kaan retreats to some caves with the other Sith Lords. When the thought bomb detonates, it destroys the Jedi and Sith armies, including Kaan, Githany, and the leader of the Jedi Army of Light, Jedi Master Hoth. In both Jedi vs. Sith and the end of Path of Destruction, Bane meets a
