Demolinn's duties included serving as a member of the security team on the Liberator, an Imperial I-class Star Destroyer belonging to the New Republic, when it crashed on Coruscant. After the crash, General Wedge Antilles tasked Demolinn, along with Mr. Greybird, with protecting Rivoche Tarkin, a journalist from the New Republic, as she investigated the devastated urban landscape and looked for anyone who had survived the Imperial reconquest of the planet.
