Mount Pasvaal, situated on the river moon Al'doleem within the Mid Rim, was a mountain with a hollow interior. At its peak, a Jedi monastery was built, and inside the mountain was a complex network of tunnels, chambers, and temples. The Jedi Order utilized Mount Pasvaal for millennia as a repository for a multitude of artifacts, notably numerous holocrons. Following the ascent of the Galactic Empire, the artifacts were removed from Pasvaal, and it was transformed into a heavily guarded military base. The Empire, referring to it as Pasvaal, revealed a section of the mountain's interior and repurposed numerous chambers into expansive hangars that towered above Am'balaar City.
