The Sith planet during the Sith and Jedi Civil Wars. Korriban is the sole planet in the Horuset System. It was used as a graveyard for Ancient Sith and was later reborn as a home and training ground for modern Sith. It was once a slave world of the Infinite Empire many millennia before the first Sith Lords came. Sith Lord Naga Sadow built his tomb millennia later around the Star Map, a relic of the time when the Rakata had used the Star Forge. Carved into the sheer rock walls of these canyons are immense tombs containing the desiccated, mummified remains of the various Dark Lords of the Sith like Marka Ragnos, Naga Sadow, Ludo Kresh, and Ajunta Pall as well as other powerful Dark Masters from various millennia.
