Korriban
this remote planet was the seat of the ancient Sith race. Korriban was the sole planet in the Horuset System, located across the galaxy from Cinnagar and Koros Minor. It was orbited by seven moons, and was unknown to the Old Republic before the rise of Naga Sadow. It was to Korriban that the ancient Dark Jedi fled, after they were exiled by the Jedi Knights. Korriban was a desolate world which, under the pall of Sith magic, became more hellish and dangerous. The native life there was twisted by the Dark Side, and the ghosts of Sith Dark Lords buried in the Valley of the Dark Lords roamed everywhere. The Sith Lords erected huge palaces and burial complexes, which honored not only the dead Lords but the current magicians as well. These ancient Sith enslaved the local population and put them to work building a huge monastery and excavating the Valley of the Dark Lords, then killed the planet's inhabitants once the jobs were done. Exar Kun was led here by Freedon Nadd's spirit, in an effort to recover certain Sith manuscripts. In the wake of the Great Sith War, the planet was virtually abandoned, although a few settlers managed to eke out a meager living. Those Jedi Knights who remembered Korriban, either through research or direct experience, referred to the planet as the 'cradle of darkness.' After the Battle of Naboo, the Commerce Guild established a base of operations on Korriban, ostensibly to attract corporations to a tax-free environment. The true nature of the Guild's presence was the accumulation of a droid army, in anticipation of supporting the Confederacy of Independent Systems. Years later, Emperor Palpatine often visited Korriban, to help him center himself in the Dark Side of the Force.
