Crystalline memory plaque
Crystalline memory plaques were information storage devices that were prevalent around the time of the Grand Sith War, and were considered ancient by the time of the Galactic Civil War. Large numbers of the plaques were stored on Exis Station, containing a wealth of knowledge about the Jedi Order. Tionne, a historian and musician, rescued a large amount of plaques when she visited Exis Station in 11 ABY.[1]
