Great Sith War
occurring some 4,000 years before the Battle of Yavin, the Great Sith War saw the Sith rise up once again in opposition to the Jedi Knights. The onset of the Great Sith War can be traced to the Freedon Nadd Uprisings on the planet Onderon, which planted the seeds for the Krath to grow in strength. When Exar Kun began to investigate the lore of the ancient Sith, against the wishes of his Master, Vodo-Siosk Baas, he fled the Jedi Order and was lured to the Dark Side of the Force by the spirit of Freedon Nadd himself. On Yavin 4, Kun discovered a wealth of Sith treasures, and set out to become a Dark Lord of the Sith. He confronted Ulic Qel-Droma on Cinnagar, where the former Jedi had also fallen to the Dark Side after battling against Satal and Aleema Keto and Krath. Rather than have the two great warriors destroy each other in battle, the ancient Sith spirits declared Kun to be the Dark Lord and Qel-Droma to be his apprentice. Together, they launched a series of campaigns against the Old Republic and the Jedi Knights, eventually reaching Coruscant. There, Exar Kun killed his former Jedi Master and ordered his followers to murder their Masters in turn. Kun and Qel-Droma then launched an assault on Ossus, in an effort to destroy the Jedi archives located on the planet. Kun was defeated on Ossus, and fled to Yavin 4, while Qel-Droma was stripped of his connection to the Force by Nomi Sunrider. He agreed to lead the combined forces of the Republic and the Jedi to Yavin 4, to take the battle of Exar Kun. At Yavin 4, the Jedi won the battle, but at a great cost. They had to unite as a single force, and wiped out much of the jungle on Yavin 4 in order to destroy Kun's body. Kun, however, managed to escape to the spiritual plane by draining the life-energy from the enslaved Massassi.
