Serper, Wyron
this Alliance undercover agent was a sensor specialist, and once infiltrated the Imperial Star Destroyer Avenger in order to rendezvous with potential defectors. He served at Hoth's Echo Base as a sensor and communications expert, using his knowledge of Imperial starship sensor images to filter out possible Imperial starships from the Hoth asteroids. Unfortunately, Captain Serper and his team were killed during the Battle of Hoth, after Imperial forces managed to breach the main base. Serper ordered his team to evacuate, but a squad of snowtroopers trapped them in the command center, killing them all on sight.
