A Bajoran artist who marries Jake Sisko in the alternative future of The Visitor and who eventually leaves him as his search for his lost father consumes his life.
Korena appears in the fourth-season Deep Space Nine episode The Visitor, in the timeline that follows Benjamin Sisko's apparent death aboard the Defiant. Jake, by then a successful novelist living on Earth, meets and marries her, and for a time they are happy.
When his father briefly reappears, pulled out of subspace for a few minutes, Jake learns that he is still alive and trapped. He gives up writing to study subspace mechanics and find a way to free him.
Korena supports him at first, but the obsession leaves no room for their marriage and they part. The elderly Jake tells the story to a young visitor, Melanie, and his final sacrifice restores the original timeline, in which none of this occurs.
