Echo Stone

The Echo Stones were powerful Force artifacts that originated from the mysterious Planet X that acted as conduits for both the light side and the dark side of the Force. Echo Stones could amplify one's connection to the Force and allow it to be wielded in unpredictable ways. The Sith Lord Darth Ravi sought the power of the Echo Stones. The Tolemite people placed Echo Stones in three rods, which gave them the power to control the Nameless, creatures who fed on the Force and also originated from Planet X.

During the High Republic Era, Jedi Master Barnabas Vim and Padawan Vix Fonnick traveled to Angcord in search of artifacts, coming across an Echo Stone. The artifact was shattered by the Jedi and the shards were scattered across the galaxy. After their mission, Vim dedicated his life to studying the Echo Stones and discovered one in the possession of Jedi Master on Petris Major. Vim then attempted to return both of of the Echo Stones in his possession to Planet X, but his ship was damaged in the planet's Veil and he was never heard from again.
