Tulak Hord

Tulak Hord was a Dark Lord of the Sith around 5000 BBY. He was considered to be one of the best lightsaber duelists in history, a remarkable feat for his time, when lightsaber combat was perhaps at its zenith. He wore a claustrophobic black mask, making him a fear-inspiring sight.

It is unknown how he died, but his power was so considerable that a burial chamber was built in his honor in the Valley of the Dark Lords, along with greats such as Marka Ragnos and Naga Sadow.

He was said to have been buried with a holocron containing his teachings on lightsaber dueling, a considerable artifact.
