Chem was a Human male who was in his youth during the Yuuzhan Vong War, a conflict spurred by the invasion of the extra-galactic Yuuzhan Vong in 25 ABY. His mother was a diplomat who collected pristine starfighters. On his fourteenth birthday, Chem left home to join Kyp's Dozen, an elite starfighter squadron headed by Jedi Master Kyp Durron. He stole his mother's most prized possession, a prototype of the T-65XJ X-wing starfighter, to fulfill his goal. Locating Kyp's Dozen, Chem spent several months following the squadron around before being accepted into the unit. He fought during the fall of the galactic capital, Coruscant, and was killed during the engagement when his fighter was hit by enemy plasma fire.
