- "If there is anything that I've learned from you, from your reaction to me, it's that I have no place out there. Other Klingons will not accept me for what I am."
Ba'el was the daughter of the male Romulan Tokath and the female Klingon Gi'ral, living in the Romulan prison camp on Carraya IV, where Klingons and Romulans lived peacefully together following the Khitomer Massacre of 2346. She also had a sense of tolerance between the two races because she was half Klingon and half Romulan.
Her first contact with the outside world came in 2369 when Worf came to the camp. Worf discovered Ba'el bathing in a pond, and Ba'el fell in love with him. Worf responded to the romantic overtones until he discovered that she was part Romulan. She protected him when Tokath was going to kill him for influencing some Klingons to leave by standing in front of him when as her father's men aimed their weapons at him. Ba'el stayed at the camp as she felt she would not be accepted by either the Klingons or the Romulans. (TNG: "Birthright, Part I", "Birthright, Part II")
The script for "Birthright" describes Ba'el as "a young and beautiful KLINGON WOMAN."  Of her and Worf's second meeting, in the village, it says, "She is the first person in the camp to hold his gaze, and Worf returns it without realizing it... suddenly they both become embarrassed and look away." 
Ba'el appeared in the Star Trek: Klingon Empire novel A Burning House, in which the camp on Carraya IV was attacked by Gorrik, son of Gannik, leaving Ba'el as one of only three survivors. She was later found and rescued by former camp resident Toq, who took her back to Qo'noS, where she reunited with Worf, then Federation Ambassador to the Klingon Empire. Worf helped her secure a job at the Federation Embassy as an assistant to events coordinator Eduardo Mazzerone.
