"In the fictional Star Wars universe, Tulak Hord was one of the Dark Lords of the Sith buried in the Valley of the Dark Lords on the planet Korriban. First featured in the video game Knights of the Old Republic, Tulak Hord was claimed by Kreia in the sequel game to be the greatest lightsaber duelist the Sith have ever known (at that time) and thus possibly the Sith's greatest lightsaber duelist ever. It is unknown what stance of lightsaber dueling Hord practiced, but the only other speculated successor in dueling skill would be Darth Tyranus or Luke Skywalker.
It has been rumoured the the Lightsaber form Hord used was a Pre-version of Form VII used by Mace Windu, a credit to his prowess as a saber duelist. Kreia also had mention that he had made a holocron of his fighting technique, something that Windu and other might have discovered."
