Roana was a Bajoran shopkeeper.
With her husband, she ran a shop on Bajor from 2344 to 2361 during the Cardassian Occupation, then on the Promenade of Terok Nor / Deep Space 9, until his death in 2370.
While closing up shop following the death of her husband, she was approached by con artist Martus Mazur, who convinced her to reopen the shop as a gaming club with him running the operations. He pretended to have a romantic interest in her in order to obtain her backing.
Upon discovering his deception (and finding him in the arms of a dabo girl), she evicted him. (DS9: "Rivals")
Roana was played by Barbara Bosson.
Her name comes from the script.
