Sith Empire expansion

At some point after an invasion by the Infinite Empire of the Rakata species and a civil war on their homeworld Korriban around 27,700 BBY, the Sith Empire led by the successors to King Adas undertook an expansion of its territories using captured Rakatan technology. The Massassi warriors were unleashed to conquer neighboring worlds, destroying the homes of disobedient people. The Sith were believed to have reached the natural edge of their space—including worlds such as Jaguada, Krayiss II, Khar Delba, Rhelg—conquering worlds beyond the Stygian Caldera, such as Malachor V, Tund, Thule, and Arorua. They attacked the Galactic Republic-controlled planet Draethos, and engaged in raids at Quermia, Felucia, Gand, and Florn.
