The office of Tierny was an office space utilized by Agent Tierny of the First Order Security Bureau. This office was located on the First Order's Thunderer, a Resurgent-class Star Destroyer, during the First Order-Resistance War. During the Thunderer's mission to hunt down the Colossus supertanker fuel depot in 34 ABY, the personal comlink belonging to First Order cadet Tamara Ryvora was kept in this office by the agent. Ryvora later met with Tierny in the office, and during this meeting, she observed where Tierny had put the device.
Later on, Supreme Leader Kylo Ren used the Force to force Tierny and Commander Pyre to aim their blaster weapons at each other while they were in the office. When Ryvora decided to defecting from the First Order, she stole her comlink from the office, assisted by 5-L, an MSE-6 series repair droid. The office and the rest of the Thunderer were eventually destroyed in the Barabesh system during a battle against the Resistance.
The office of Tierny served as the personal workspace for Agent Tierny of the First Order Security Bureau while she was aboard the First Order Resurgent-class Star Destroyer Thunderer. The room was characterized by paneled gray walls, a black floor, and a sizable viewport. Tierny's office also featured a collection of her personal weapons, displayed in two illuminated, transparent cases positioned on opposite walls. This collection included five bladed weapons, four rifles, and a single blaster. A black, semicircle-shaped desk with storage compartments and a holoprojector was situated near the viewport.
Tierny had a personal office on the Thunderer during the First Order-Resistance War. In 34 ABY, First Order cadet Tamara Ryvora surrendered her personal comlink to her superiors for use in their hunt for the Colossus supertanker fuel depot. Despite the Thunderer's initial attempt to destroy the vessel being unsuccessful, Tierny stored the comlink in her office.
Shortly after, in that same year, Tierny summoned Ryvora to her office to question her loyalty and commitment to the First Order. The agent shared her personal history with the cadet, playing with Ryvora's comlink after retrieving it from the office's desk drawer. As Tierny confessed her initial doubts about Ryvora, the cadet paid attention to where the agent placed the device when returning it to the drawer. After the Thunderer arrived at planet Dantooine in the Outer Rim to confront Resistance operatives, the agent dismissed the cadet from the room.
Soon after, Tierny and Commander Pyre reported their successful decimation of the Aeos system to General Armitage Hux in the office via hologram. However, Supreme Leader Kylo Ren replaced Hux in the projection and criticized Tierny and Pyre for their continued failure to locate the Colossus, using the Force with to force them to draw their blasters and aim them at each other. Once released from the Force's influence, Tierny and Pyre decided to intensify their efforts and left the room.
Immediately after they left, Ryvora, with the help of the reprogrammed MSE-6 series repair droid 5-L, secretly entered the agent's office and took her comlink from the desk, planning to flee the First Order. When Tierny returned to her office, she was distracted by 5-L's presence, which allowed Ryvora to leave the room unnoticed as the agent questioned the droid, who only beeped at her before hurrying away.
After Ryvora's training squadron made a hyperspace jump to the planet Castilon—the original home of the Colossus—Tierny grew suspicious of the recruit's intentions and went to her office. Upon discovering that the cadet had taken her personal comlink, she deduced Ryvora's plan to meet with her former colleagues and ordered the Thunderer to travel to Castilon. Shortly thereafter, the office—along with the entire Thunderer—was destroyed in the Barabesh system during a battle against the Colossus.
The office was first shown in "Rebuilding the Resistance," the seventeenth episode of the second season of the animated television series Star Wars Resistance, which was broadcast on January 19, 2020. The location was initially identified as Tierny's office in the episode's related concept art gallery. Colas Gauthier, an artist at Lucasfilm Animation, created two concept art pieces for Tierny's office for "Rebuilding the Resistance"—one depicting the room aboard the Thunderer and one showing the weapons displayed in the room's wall cases, both dated September 20, 2018. In the early stages of the episode's development, the scene in the office was intended to open the episode as a teaser before the title, but this idea was eventually changed.
