Flim was a con artist who was hired by Moff Vilim Disra in 19 ABY to play the role of a resurrected Grand Admiral Thrawn. In this capacity, he—under the directions of Disra and fellow triumvirate member Grodin Tierce—successfully convinced several officials within the Imperial Starfleet to follow his authority in a plan to cause a civil war within the New Republic. While Flim pretended to be the Grand Admiral, Tierce was the military man who came up with the battle plans.
