T'Leena was a fiction female Vulcan, the main character in a holosuite program created by Marc Tomson in which T'Leena was his lover. T'Leena wore a tight gauzy outfit. The narrative of the T'Leena program runs as follows:
- Tomson: "T'Leena, what are you doing here?"
- T'Leena: "I don't know, I don’t understand. It is not logical, it is not Vulcan."
- Tomson: "But..."
- T'Leena: "You make my cool green blood burn like a stream of fiery emeralds, Marc Tomson. My time is years away, but when I look on you I feel the passion of the pon farr."
- Tomson: "What do you want from me?"
- T'Leena, removing her robe: "I want to meld with you, Marc Tomson. I want to explore infinite pleasures in infinite combinations. I want to teach you the ancient secrets of Vulcan love... Every seven years is not enough, not enough for you..."
Tomson was running the T'Leena program when a baby Horta burned into the simulation, emerging, to the ensign's surprise, between his legs. In response Tomson ran out of the holosuite and through Quark's naked. (DS9 novel: Devil in the Sky)
