Kursid was a planet in Esstran sector of the Outer Rim Territories of the galaxy. It was inhabited by a bellicose species of primitive humanoids whose sole contact with the greater galaxy was through training missions conducted to the planet by the Order of the Sith Lords.
At some point many centuries before the fall of the Republic, the world's location was deleted from the Republic records; starting around 650 BBY, it was frequently visited by members of the Order of the Sith Lords, who knew it as "Kursid." On the occasions of their visits, the Sith sought battle with the Kursid natives in an arid plateau on the part of the planet where they landed, and engaged large numbers of them in combat in order to hone their skills. Despite the hostile intentions of the Sith, a cult centered on the periodic returns of the sky visitors eventually developed on that part of the planet.
The Sith Lord Darth Tenebrous traveled to Kursid with his apprentice, Darth Plagueis, c. 104 BBY; approximately fifty years later, Plagueis, now a master, journeyed to the world with his own apprentice, Darth Sidious.
