Naradan D'ulin served as a Mistryl Shadow Guard. In 33 BBY, she was part of the guard detail for Princess Foolookoola, and she harbored a deep suspicion of Devaronians. With her dark hair, it is speculated that she might have been a forebear of Karoly D'ulin.
Following the coup staged by a faction of radical Ootoolaner purists against the Ootoola royal family, Naradan managed to escape with Foolookoola and Major Sabon. To ensure her protection during their escape, they enlisted the services of Vilmarh Grahrk, a Devaronian smuggler. D'Ulin was extremely wary of Grahrk because of her general distrust for his kind.
During their mission, Naradan and Vilmarh were captured by the purists; however, Vilmarh's staged betrayal led to their release, and he safely transported them to Dur Sabon. After the journey, D'Ulin chose to stay with the princess, continuing to provide her with protection.
