Sliro Barsha, also known as Sliro Rubak, is a human male who serves as the Director of the Imperial Security Bureau of the Galactic Empire. During the Galactic Civil War, he served as the crime lord of the Jarek Besh crime syndicate, secretly acting as the ISB's intelligence operative, extracting intelligence from various criminal organizations in the galaxy, and the Alliance The Republic would infiltrate the Underworld in search of restoration.
As a child, Sliro was part of the wealthy Barsha family of Corellian industrialists. His father believed him wrong, and his younger brother Jalen Wrax was the favorite son and heir to the Barsha family. The pressure of family expectations and underestimation made Sliro's childhood difficult, and he despised his father and brother.
After the end of the Clone Wars, the Barsha family was to secure a contract to manufacture Star Destroyer for the newly founded Galactic Empire, which would have made them the most powerful family in Corellia. However, Sliro sold Vrax and the rest of his family to the Empire, and was promoted within the Imperial Security Bureau in return for his services. During this time, He programmed the ND-5 droid BX series to hunt down and kill every member of the Barsha family. However, his brother Vrax was able to reprogram the ND-5, using him as a bodyguard to begin a mission to track down Sliro and avenge his family.
Sliro Barsha rose to power in the ranks of the ISB and, after the tactical failure that was the Battle of Hoth, was tasked with creating a special division that would disguise itself as an underground organization to generate a reaction from the Rebel Alliance, which had smugglers and... criminals. For their mission, this division, called Jarek Besh, had the ultimate goal of uncovering the new Rebel Alliance base of operations and controlling its leadership. Barsha was made director of the ISB and assumed ultimate authority over Jarek Besh as his "criminal".
During that year, the criminal Canto Bight was hired by Denion, an undercover agent for Wes's Alliance, as part of a team to rescue Asra Dane from Barsha's mansion under the pretext of a feud between the two organizations. Wes successfully broke into one of Barsha's safes, but after learning that there were no credits inside, He then demands payment as promised. Dane and Danion try to reason with him, but Wes threatens them with a blaster. In response, Danion stuns her and flees, leaving her to go after Barsha and Jarek Besh. Finding Dane missing and Wes alone in the vault, Barsha questions him about his contacts with the rebels, but Wes escapes with the help of his pet Merkal Nix. Despite being pursued by Westhill's security, Wes makes it to Barsha's private hangar and escapes Cantonica by stealing his Trailblazer, a small EML 850 cargo ship.
