C'ai Threnalli was an Abednedo male who flew in the Resistance Starfighter Corps of the Resistance's military during their conflict with the First Order. Following the Assault on Starkiller Base in the year 34 ABY, Threnalli was amongst the personnel in the Resistance base on the planet D'Qar who waved off the YT-1300 light freighter known as the Millennium Falcon as it set off to find the missing Jedi Master Luke Skywalker on the planet Ahch-To. Threnalli had brown skin and hair and black eyes. He wore an orange flight suit. Shortly after the Resistance evacuated the base on D'Qar, Threnalli flew as Commander Poe Dameron's wingman.
