Javis Koldor was a Sith Lord belonging to the reconstituted Sith Empire. This male Sith lived during the times of the Great Galactic War, the Cold War, and the [Galactic War].(/article/galactic_war)
Circa 3640 BBY, Koldor served as the captain of the Scream of Ragnos, a notorious Harrower-class dreadnought within the Imperial Navy of the Sith. This vessel was among the capital ships involved in the Sacking of Coruscant, where numerous members of the Republic forces met their demise.
In the Zosha system, Republic intelligence managed to intercept the Scream of Ragnos while it was on an escort assignment. The Republic command saw this as an opportunity to eliminate the dreadnought, and dispatched a member of the Coruscant Aegis Squadron, reinforced by a minimum of three Thranta-class corvettes, with the purpose of destroying it. The Scream of Ragnos was subsequently destroyed, resulting in the death of Javis Koldor.
