Oubliette was a shadowport hidden in the northern rim of Old Soren on the planet Ord Vaxal. It was owned and maintained by the Besadii kajidic of Hutts who were represented on the planet by Sassallo the Hutt.
Most of the shadowport remained underground with the few above ground areas designed to blend in with the ruins of Old Soren. Oubliette was used as a staging ground for operations in and around Tof Soren with the purpose of capturing slaves. Oubliette was also sometimes used as a hiding place for 'hot' items and individuals.
