Kirrek
this was one of the seven primary planets in the ancient Koros System, which was later known as the Empress Teta system. When Empress Teta attempted to join the seven worlds of the Koros System into a single alliance united by commerce and aid, Kirrek was the world which resisted the hardest. Pirates and rebels on the planet ignored or attacked any contingent sent to discuss the alliance, and a civil war broke out that marked the final battles of the First Unification Wars. Teta petitioned the Old Republic to send help in quelling the battle, and the Jedi Knight Odan-Urr was dispatched to assist Memit Nadill in mediating the battle. Odan-Urr brought with him the concept of Jedi battle meditation, and together they were able to convince the rebels on Kirrek to surrender their arms long enough to negotiate a peace treaty. A thousand years later, Kirrek's three main cities were destroyed just before the Great Sith War, when they refused to submit to Satal Keto and Aleema.
