Sajin was a Human male Corporal of the Galactic Republic. During a mission on Hoth, Sajin was part of Yuun's squad until they were ambushed by Sith Imperials. An unidentified Republic trooper was able to drive them out while Sajin was badly wounded from the attack. The Havoc Squad medical specialist, Elara Dorne, did all she could to ease Sajin's pain, but the injuries were fatal. Sajin asked the captain to warn about the cause and died from his wounds. The captain fulfilled that promised.
