Korriban

A Sith World. During the Dark Lords along with the Jedi Civil Wars. This world has the sole planet located in the Horuset System. It was used as a graveyard for Ancient Sith Lords and was later rebirth as a home and training ground for modern Sith. It was once a world of slavery of the Infinite Empire thousands of years before the first Sith Lords came.

Naga Sadow built his tomb millennia later around the Star Map, a artifact of the time when the Rakata had used the Star Forge. Carved into the sheer rock walls of these canyons are enormous tombs containing the dried, mummified remnants of the a range of Dark Lords of the Sith like Marka Ragnos, Naga Sadow, Ajuna Pall, and Ludo Kreesh as well as other great Dark Masters from various millennia.Korriban was occupied by the Sith race.

The Dark Jedi astonished the Sith with their teaching in the Force, and soon grand themselves to a God type, becoming the rulers (or considered themselves as "Lords of the Sith"). As the years passed, interbreeding occur between the human Dark Jedi and the Sith, until at final 2 people had become one. Korriban now as a graveyard for all the Sith who died throughout the wars, many artifacts are rumored to be in the Sith Academy.
