As an ensign in the Republic Army during the Cold War, Cav was a male Human. He was stationed on the planet of Taris with Search and Rescue Squad 204. Sergeant Elara Dorne was Cav's commanding officer. When the squad arrived at the Fallenspire Stronghold located on Taris to save Republic soldiers who had been captured, Elara instructed Cav to watch over the bunker's exit.
