T'Rul

T'Rul (played by Martha Hackett) was a Romulan Subcommander assigned to Deep Space 9 for a brief period in early 2371.

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 misued. 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. (DS9: "The Search, Part I")

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: "The Search, Part II")

In 2374, she was assigned to Project Blue Sky and worked with Jadzia Dax to create an enzyme to alter the genetic profile of the Jem'Hadar. (Prophecy and Change: "The Devil You Know")
