Duana was an Aldean in the 24th century, a member of Radue's First Unit and part of the leadership of Aldea.

In 2364, after several children were kidnapped from the USS Enterprise-D, including Wesley Crusher, she attempted to acclimate him to life on Aldea. She instructed him on the use of the Custodian and attempted to answer his questions concerning their world. (TNG: "When The Bough Breaks")
