The University of Charmath, located on the world of Charmath, boasted one of the most complete historical libraries in the known galaxy. Early in the Galactic Civil War, Major Arhul Hextrophon, a historian for the Rebel Alliance, found evidence there that renowned Jedi Master Yoda was alive on Dagobah. He later destroyed that evidence in order to protect the secret of the Jedi Master's existence.
