Mr. Greybird served as a member of the security detail on the Liberator, an Imperial I-class Star Destroyer belonging to the New Republic, when it crashed on Coruscant. General Wedge Antilles tasked Greybird, along with another guard named Demolinn, with protecting Rivoche Tarkin, a journalist from the New Republic, as she ventured into the remains of Imperial City to find people who had survived the Imperial reconquest of the planet.
