Dromund Kaas

Dromund Kaas was the third planet in the Dromund system, a star system in the Sith Worlds region of the Outer Rim Territories's Esstran sector. Originally a colony of the Sith Empire, its location was lost by the time of the Great Hyperspace War with the Galactic Republic, but the Sith Emperor led his people on a twenty-year odyssey that ended with the rediscovery of Dromund Kaas in 4980 BBY.
