Sorjus was a small terrestrial planet situated in the Sorjus system, a part of the Meridian sector of the Trans-Hydian portion of the Outer Rim Territories. It lay far off the super-hyperroute known as the Perlemian Trade Route. The planet's climate was much less arid than that of the Arkanis sector's desert world Tatooine.
During the Jedi Civil War of 3959 BBY–3956 BBY, Sorjus fell within the territory controlled by the empire founded by the Dark Lord of the Sith Darth Revan. At some point by the latter year, the Paaerduag Ja'Gatcha had left Sorjus, their species' homeworld, and had become a spacer whose travels took them to the planet Taris of the Ojoster sector. Around the same time, Mic'tunan'jus Orgu, who—like Ja'Gatcha—spoke a non-Basic language and also believed that Sorjus was an unimportant galactic travel stop, was another Paaerduag who had traveled offworld, eventually becoming a merchant on Tatooine.
Sorjus was the homeworld of the sentient Paaerduag species, members of which were a composite of two fused beings. The planet's true name was unpronounceable by species whose members spoke with a single voice—such as Humans—and "Sorjus" was merely a name that such species could use. The Paaerduag Mic'tunan'jus Orgu believed that the latter name had originated due to the need for such a word to exist for the purpose of use by the commerce along the interstellar trade routes.
In Star Wars: Knights of the Old Republic, Sorjus can be mentioned by the Paaerduag character Ja'Gatcha.
Sorjus was introduced in the 2003 BioWare video game Star Wars: Knights of the Old Republic. In the accompanying Prima Games' strategy guide, "Sorjus" is erroneously given as the species name of the Paaerduag character Mic'tunan'jus Orgu. The 2009 reference book The Essential Atlas placed the Sorjus system, and therefore the planet itself, in grid square R-7.
In Knights of the Old Republic, Sorjus can be mentioned in two similar optional conversations the Human player character, Revan, can have with the Paaerduags Ja'Gatcha and Mic'tunan'jus Orgu. If Revan asks Ja'Gatcha if they can tell them more about Sorjus, the spacer replies that they would rather not be reminded of their homeworld due to it making the quarantine imposed on the planet Taris by the Sith at the time harder to bear, and that they wished for that state to end so that they could return home.
