Mount Pasvaal was a hollow mountain located on the river moon Al'doleem in the Mid Rim. A Jedi monastery was located on the summit of the mountain, while the interior of the mountain itself was a labyrinth of tunnels, chambers, and temples. For thousands of years, the Jedi Order used Mount Pasvaal as a storehouse for artifacts, including countless holocrons. With the rise of the Galactic Empire, Pasvaal was emptied of artifacts and converted into a high-security military installation. Code-named Pasvaal, the Empire exposed a side of the mountain's interior, and converted several chambers into large hangars which loomed over Am'balaar City.
