A Romulan diplomat, in 2287 Dar was assigned to the Paradise City settlement on Nimbus III. A youthful idealist, Dar believed that Paradise City could still serve as a catalyst for galactic peace, despite the failure of the project for two decades. She joined Federation representative St. John Talbot and, from the Klingon Empire, General Korrd. Under Sybok's mental manipulation, Dar later left her post to join Sybok in his quest for Sha'Ka'Ree.
