During the Long Winter in Narnia, Vardan was one of the many followers of Jadis the White Witch. He was a member of the Witch's Secret Police led by Maugrim and likely the second in command. He first appears when the wolves went after the Penvensies at the Beaver's home. The Pevensies fled and the wolves followed and eventually tracked them down to Aslan's Camp. He and Muagrim attacked the Pevensies but he was restrained by Aslan. He then witnessed Muagrim getting killed by Peter. Vardan then managed to escape and he reported to the Witch and told her everything that happened. The Witch then ordered him to fetch her army so they can fight Aslan's Army. Vardan however was followed by Aslan's men who managed to rescue Edmund from the Witch.
It is unknown what happened to him after this.
