Tierny

Tierny was a human female who served as an agent in the First Order Security Bureau during the conflict between the First Order and the Resistance. In 34 ABY, she was sent to the supertanker fuel depot Colossus on the planet Castilon to root out the Resistance presence on the station. While there, she interrogated the mechanic Tamara Ryvora, whose colleagues Kazuda Xiono and Jarek Yeager worked for the Resistance. After presenting herself as caring and sympathetic, Tierny manipulated Ryvora into joining the First Order as a pilot and betraying Xiono and Yeager, making the mechanic believe they never cared about her. Tierny, Commander Pyre, and Ryvora fled the Colossus before its jump to hyperspace, boarding the Resurgent-class Star Destroyer Thunderer, where Ryvora was accepted as a First Order cadet. Over the following months, Tierny and Pyre pursued the Colossus across the galaxy. Using Ryvora's comlink, they tracked the station to the planet D'Qar but were unable to prevent the platform from escaping. Tierny devised a plot to have an engineer—Nenavakasa Nalor—sabotage the Colossus, but it proved unsuccessful.

After tracing the station's signal beacon through space, the Thunderer again failed to capture the Colossus but instead captured a Resistance pilot—Venisa Doza—who had been trying to rendezvous with the refueling station. Although Doza escaped detainment, Tierny continued to pursue the Colossus alongside Pyre. On the planet Varkana, the agent tortured the Colossus residents Yeager and pirate Synara San to acquire the station's location. However, before the officer could question the pair further, she was knocked out by the Resistance droid CB-23, and they fled the world with Xiono and the Resistance spy Norath Kev. Next, following a report from a probe droid, Tierny and Pyre traveled aboard the Thunderer to meet with the Colossus on the planet Aeos Prime, where the station had been attempting to settle permanently. Upon again failing to capture the station, she encountered the Resistance and some Colossus Ace Squadron pilots over the planet Dantooine, who were escorting shuttles of recruits offworld. Although the First Order only destroyed one of the three escaping shuttles, Tierny comforted Ryvora about the failure and promoted her to squadron leader.

Afterward, the agent and Pyre returned to Aeos Prime to lead its bombardment. Ryvora eventually grew disillusioned with the First Order and chose to defect, taking her comlink from Tierny's office and meeting with her former colleagues on Castilon. After the First Order captured Ryvora and the colleagues she had been intending to meet—Yeager, Xiono, and CB-23—Tierny confronted her about the betrayal. The Thunderer then traveled to the Barabesh system to confront the Colossus again, having learned its location from the First Order pilot Jace Rucklin. However, as the Colossus successfully repelled the Thunderer attacks, Tierny was executed for her failure by Supreme Leader Kylo Ren.
