Luke Skywalker on Korriban in Star Wars Battlefront: Renegade Squadron
Korriban was the burial planet of the Sith, where many of the old Sith Lords as well as other Sith were buried. Most of the tombs were located in the Valley of the Dark Lords, which was the opposite of the Valley of the Jedi that had tombs of Jedi on the planet, Ruusan.
Korriban was also the home of the Sith Academy during the Jedi Civil War.
