Great Hyperspace War
an ancient battle between the minions of the Light and Dark sides of the Force, the Great Hyperspace war erupted on the heels of the First Unification Wars fought in the Koros System, some 5,000 years before the Battle of Yavin. The ancient Sith lords, led by Ludo Kressh and Naga Sadow, fought for control of their minions while Sadow attempted to take control of the galaxy. Meanwhile, the Jedi Knights Odan-Urr and Ooroo tried to use Jedi battle meditation on the advancing Massassi forces, but the Massassi mind was too primitive to be persuaded. The Massassi, under the control of the Sith, swarmed the planet Coruscant, but the Jedi soon realized that the majority of their army was illusional. The Jedi quickly dispatched the true Massassi and free the planet. Meanwhile, Sadow had defeated Kressh in an epic interstellar war in the Sith Empire, but his forces were unable to defend themselves against the might of Empress Teta's forces. As his commanders began to surrender, Sadow used the Dark Side of the Force to communicate with his Massassi spies. They executed Sadow's enemies and took control of their ships, drawing Teta's forces into the Denarii Nova. There, Sadow's forces were eradicated, along with many of Teta's ships, but ultimately the Old Republic was able to eliminate the Sith threat. Sadow was forced to flee, and later established his own base on Yavin 4.
