Chox was a Ununian soldier in the army of Urum until the beginning of the Qorox War in the Urum system in 201 ABY. Chox was very smart and when he joined the army, he was trained to become a captain. In 201 ABY, he had his first mission to stop the invasion on Urum but this failed. The Urum Army was almost destroyed, and the surviving soldiers had to flee. However, a small squad led by Cohu and Dux stayed together, and they gave their squad the name, "Mist Squadron."
