A Sith wayfinder is a pyramid-shaped device created by the Sith to guide the way to the hidden Sith world of Exegol. Only two wayfinders existed with one belonging to the deceased Darth Vader which was located on Mustafar and the other in the possession of Darth Sidious which was located in the wreckage of the Death Star II on the ocean moon of Kef Bir.
Sith wayfinders were shaped like holocrons and were made from Kathol resin. Sith wayfinders acted as hyperspatial lodestones, allowing safe passage through the Unknown Regions to Exegol, the hidden world of the Sith.
The astronavigation systems of starships could be adapted to accept the binary signals emitted by the wayfinders and interpret them as hyperspace jump coordinates. Kylo Ren adapted his TIE whisper in this way to locate Exegol, and Rey later did the same to Luke Skywalker's X-wing for the same purpose.
The ancient Sith created two wayfinders, pointing the way to their secret location of Exegol via the Red Honeycomb Zone in the Unknown Regions. Each wayfinder was entrusted to a Sith Lord, a title which, was limited to a Sith Master and a Sith apprentice.
As the last Dark Lords of the Sith, Darth Sidious and Darth Vader were each owners of the Sith wayfinders that revealed the path to Exegol. Sidious, who ruled the Galactic Empire as Emperor Palpatine, stored his wayfinder in a secret chamber adjacent to his throne room on the Death Star II at the time of the Battle of Endor. The other wayfinder was located within Vader's castle on the volcanic world of Mustafar. After their deaths and the end of the Galactic Civil War, both wayfinders remained hidden for decades.
- A Sith wayfinder can be easily mistaken for a Sith holocron because its shape and size being similar to that of a holocron.
