In an alternate timeline, Korena Sisko was a Bajoran woman who married Jake Sisko. They were married for over eight years, but separated and then divorced. Jake's obession with saving his father from a temporal flux that had trapped him in subspace caused him to ignore Korena's needs and abandon his writing. (DS9: "The Visitor")
Korena was played by Galyn Görg.
In the relaunch novel series, following the end of the actual television series, Worlds of Star Trek: Deep Space Nine, Volume 2 shows that Jake Sisko married the same Azeni Korena as he became dissatisfied with his life living in the Kendra Province with a returned-from-the-Prophets Ben Sisko, as well as Kasidy Sisko and their new baby Rebecca. When introduced to her, Benjamin Sisko recognized her as the wife Jake had in the alternate timeline he experienced.
