Deeve was an Arpor-Lan scout who served the Rebel Alliance. Using skills he had learned on his native planet Arporatal-Lanin, Deeve became one of the most respected scouts in the Alliance after scouting Wild Space and the Unknown Regions, as well as exploring the planet Apliria—which later became a safe world. After being promoted to the rank of lieutenant, he helped to establish New Alderaan in 1 ABY, and he also became a member of the Task Force on Alliance Security.
