Lost City of the Jedi
a hidden, underground city found on Yavin Four, the Lost City of the Jedi was created long ago by the Jedi Knights. Its entrance is formed by a 2-meter cylinder of green marble hidden deep in the rain forests of the moon. The exact location of the entrance was kept secret by the Jedi, although the existence of the City has been known for years. Kadann even knew the City existed, but he never found the exact location. Once the circle of marble is opened, a tube-shaped transport descends to the city itself, which was a technological marvel of its day. The Jedi Library is located in the City, the storehouse of all the greatest Jedi lore and knowledge. In order to preserve the secret of the City and its location, the ancient Jedi programmed droids to guard and protect it. These droids were the only residents of the City until the Jedi Knights hid the boy Ken there, for safe keeping until he could emerge as a Jedi. The City was eventualy damaged in the battles between Trioculus and the New Republic, and was shut down and cut off.
