The facility known as Jzoro's Bunker existed on the world of Corellia, and it was situated close to the city called Doaba Guerfel. The Chirq Council utilized this bunker during the period of the Galactic Civil War.
Following the Battle of Yavin, the bunker served as the base of operations for Jzoro Quanera. He was a Chirq Council underboss, responsible for overseeing the Chirq Council's illicit activities, especially the trade of spice, in Doaba Guerfel and its surrounding areas.
During 1 ABY, the Corellian Security Force initiated an investigation into the Chirq Council due to a surge in ryll trafficking on Corellia. Captain Vitala Baize made the decision to infiltrate the criminal organization. She took on the identity of Trins Evnar, who was a Chirq Council member operating in Doaba Guerfel. An independent spacer, who had previously been employed by CorSec, eliminated Trins Evnar, along with all other Chirq Council criminals who were familiar with him. Because Jzoro Quanera did not personally know Trins Evnar, the CorSec agent was able to successfully assume Evnar's identity and deceive the underboss. The CorSec agent then joined Quanera's organization and began working for him. After completing various assignments for Quanera, the agent finally gained complete access to Jzoro Quanera's bunker, including its database. The CorSec used Quanera's database to discover the identities of the nine elite councilors who led the Chirq Council, as well as the locations of their secret headquarters.
At approximately the same time, a group of Chirq Council members in Quanera's employment stole three racing durnis that were owned by the animal handler Galvain Tark. Later, a spacer managed to infiltrate the bunker and successfully rescued the three durnis.
The 2003 video game Star Wars Galaxies, a massively multiplayer online roleplaying game created by Sony Online Entertainment and distributed by LucasArts, featured Jzoro's Bunker prior to the game's shutdown on December 15, 2011. The update titled "Chapter 1: The Corellian Captives," released on June 8, 2006, added Jzoro's Bunker to the game.
