Korriban

"Korriban shall be as it always was. A graveyard for the darkest of the Sith Lords, still whispering within their tombs. It shall always be a source of evil, spawning threats throughout the millennia. It, like Malachor, brushes the edges of the empire that waits in the dark. And like Malachor, the Sith have forgotten it … for a time. They will remember."
―Darth Traya

The planet of Korriban is the sole planet in the Horuset system, located across the galaxy from Koros Major[3]. It was the original homeworld of the Sith species and a sacred planet for the Sith Order, housing the tombs for many ancient and powerful Dark Lords of the Sith, and containing tremendous dark side power.
