A Human female from Corellia, Jade McDonagh served as an adjutant within the Chirq Council during the Galactic Civil War time period.
Following the Battle of Yavin, Jade McDonagh held a position within the Chirq Council located in Doaba Guerfel, where she also operated a small junk business. In the year 1 ABY, the Corellian Security Force initiated an investigation into the Chirq Council due to increased ryll smuggling activities on Corellia. Captain Vitala Baize made the decision to infiltrate the organization by using a CorSec agent who would assume the identity of Trins Evnar, a member of the Chirq Council. To facilitate the infiltration, the agent murdered Evnar and also eliminated other Chirq Council criminals who knew Evnar, including Seyda Shae, Genovin Jasha, Kazic Pendre, and Jade McDonagh. The spacer subsequently adopted Trins Evnar's identity to deceive the underboss Jzoro Quanera and successfully infiltrated the organization. Ultimately, the CorSec operation resulted in the downfall of the Chirq Council.
