During the conflict known as the war fought between the First Order and the Resistance, a battalion of First Order TIE starfighters operated from the Thunderer, which was the Star Destroyer commanded by both Agent Tierny and Commander Pyre. Not long after the Battle of D'Qar concluded, a squadron originating from that TIE battalion engaged in a skirmish over D'Qar. Their opponents included the Resistance group Team Colossus along with the Warbird gang.
