Zuld Mar-Shayal was a male Human elite councilor within the Chirq Council, residing on Corellia during the Galactic Civil War era.
Following the Battle of Yavin, Zuld Mar-Shayal became one of the nine elite councilors heading up the criminal syndicate known as the Chirq Council. The other eight individuals in this leadership were Markus Gilder, Braganti Hooge, Koran Lassk, Janos Zarbo, Mathazar Zayet, Rallyn Secura, Crale Forte, and Atlan Dubreas. Mar-Shayal operated from the Second Elite Council Bunker, situated near the city of Doaba Guerfel.
In the year 1 ABY, an investigation was launched by the Corellian Security Force targeting the Chirq Council because of increased ryll smuggling on Corellia. Captain Vitala Baize made the decision to send a CorSec agent undercover, using the identity of Trins Evnar, a Chirq Council member based in Doaba Guerfel. After the CorSec agent eliminated Evnar, along with all other Chirq Council criminals who could identify him, he assumed Trins Evnar's identity to approach the underboss Jzoro Quanera, successfully infiltrating the criminal group. The CorSec obtained the identities of the nine elite councilors and the locations of their secret headquarters from Jzoro Quanera's database. The First and Second Elite Council Bunkers were eventually raided by the CorSec, resulting in the deaths of all the elite councilors during the operation. The Chirq Council fractured after the demise of Zuld Mar-Shayal and his fellow elite councilors.
