Mask of Darth Kayon

"Finally, it is in my grasp! Centuries of planning, and waiting. The Mask is finally in my hands! Immortality is mine, Vethra. To live forever."

- Darth Exius

The Mask of Darth Kayon was a Sith  artifact created by the Sith Lord Darth Kayon during the Old Korriban era.

The artifact was the source of a war hundreds of years later, known as the Relic Wars, during which Darth Exius searched desperately for the Mask to extend his life.
