A Human of renown, Zanner resided on the planet of Dalicron-4 throughout the Galactic Civil War era.
Born in 4 BBY, Zanner was the offspring of Corvin. When Zanner reached the age of seven, specifically in 3 ABY, a nerf belonging to his father produced offspring, and Zanner chose to take in the young nerf. Amidst a powerful storm, Zanner ventured to the barn to ensure the creature's well-being, ultimately deciding to bring it indoors. However, the nerf became frightened, causing both of them to become disoriented in the tempest. A pack of verlen detected the calf's presence and launched an assault on the animal. Just before they could turn their aggression towards Zanner, a lightning strike caused a tree to collapse upon him. He was subsequently saved by operatives of the Alliance to Restore the Republic, who transported him to receive medical attention from the Ithorian doctor named Aloor.
