Korenna Mirell (later Jora Mirell) was an Enaran female whose lover Dathan Alaris was a Regressive. Her father Jareth, a military leader, disapproved of the relationship. Dathan told her that the Regressives were being killed, not resettled, and asked her to run away with him.
She confronted her father, who swayed her and convinced her that the resettlement was legitimate, and that Dathan did not love her but was using her to influence him. She betrayed Dathan and cheered when he and Fredik were executed. Later, when she was telling young Enarans about the Regressives, she stated that they were bad people who caused trouble. She said that they were resettled and given territory of their own, but that they killed each other off.
She later discovered that her father had lied. She felt guilty about letting the Regressives be "resettled" (i.e. killed), and transferred the memories of her experience to B'Elanna Torres shortly before she died so that the incident would not be forgotten. Torres then convinced another female Enaran, Jessen, to transfer the memories to herself to keep the memories alive. (VOY: "Remember")
Mirell was portrayed by Eve H. Brenner.
Although it was not stated on screen, "Jor" and "Jora" are respectful titles given to older Enarans. (Star Trek Encyclopedia, 4th ed., vol. 2, p. 45) This is why Korenna went by the name Jora when she was aboard Voyager. As neither Torres nor the audience was familiar with Enaran traditions, Torres did not realize until late in the episode that the girl in her dreams (Korenna) was in fact Jora Mirell.
