T'Rul in 2371.
|Affiliation:||Romulan Star Empire|
|Assignment:||Project Blue Sky|
Her role there was to oversee the cloaking device that the Star Empire had installed on the USS Defiant and to make sure it was not misused. She later joined the Defiant on its mission into the Gamma Quadrant to make contact with the Founders of the Dominion. After the Jem'Hadar managed to detect the cloaked Defiant, they boarded the starship and T'Rul was hit by weapons fire.
Along with the senior staff of the Defiant, she was taken to the Founders homeworld and placed in Borath's elaborate simulation. In it, she was incensed that the Romulans had been excluded from peace talks with the Dominion. T'Rul was later rescued after Kira Nerys and Odo discovered the room where the simulation was being held. (DS9 episode & novelization: The Search)
Her family was on Cardassia Prime when the Union joined the Dominion, and were executed when the Star Empire declared war on the Dominion. (DS9 - Prophecy and Change short story: "The Devil You Know")
