Once a Human male serving the Fel Empire, Konrad Rus achieved the rank of Moff. During the tumultuous period of the Sith–Imperial War, Rus held a distinguished position on the Moff High Council and spearheaded the Imperial Mission. This organization was a direct result of Emperor Jagged Fel's initiative, known as Victory Without War. At the conclusion of the Sith–Imperial War, Rus attended the pivotal meeting between the Moff Council and Emperor Roan Fel, an event that culminated in the Emperor's deposition by Darth Krayt, the formidable Dark Lord of the Sith. Following this coup, Krayt ascended to the throne, compelling Rus and his fellow Moffs to pledge their allegiance to him as the new supreme ruler.
Throughout the Second Imperial Civil War, Rus maintained his leadership role within the Imperial Mission. After Darth Talon's attack targeted the Imperial Mission temple located on Socorro, he was contacted by Missionary Astraal Vao. Vao, who had been secretly supporting Roan Fel's Empire-in-exile and serving as an advisor to Princess Marasiah Fel, confided in Rus. Despite Vao's trust, Rus betrayed her confidence by revealing this information to Darth Krayt. Later, Rus and the other Moffs were given the task of finding Cade Skywalker, a bounty hunter who previously served as a Jedi. As the Sith successfully captured Skywalker, doubts about Rus's dedication to Darth Krayt began to surface among the other Moffs, with some even suspecting him of being a spy for Roan Fel. However, Rus's primary allegiance was to the Imperial Mission, and he was prepared to cooperate with any Emperor who would allow the program to continue its objectives.
His position granted him membership in the Moff High Council, where he demonstrated his skills as a political negotiator. Despite his reserved demeanor, he often opposed the more aggressive viewpoints held by the majority of the Council.
Rus, along with the rest of the Council, bore witness to Darth Krayt's seizure of the Emperor's position in 130 ABY. One of the first actions taken by the Sith Lord was to demand allegiance from the Moffs, a request that Konrad Rus, along with his colleagues, complied with.
Even as he served under Krayt, Rus maintained a reputation as a good man in the eyes of subordinates like Missionary Astraal Vao. In 137 ABY, Astraal, stranded on Vendaxa, showed her trust in him by revealing her location, as well as that of Princess Marasiah Fel, the daughter of Emperor Roan Fel.
However, Moff Rus promptly relayed this information to Darth Krayt. After learning that Krayt intended to subject Princess Sia to Sith torture in order to discover her father's whereabouts, he even proposed luring Roan Fel into a Sith trap on Vendaxa, utilizing his contacts within the Empire-in-exile. This was done to avoid the "unpleasantness" of brutally interrogating a young woman.
It appears that Konrad Rus was primarily motivated by the belief that serving whoever controlled the Empire would allow the Mission to continue its work. His loyalty to Krayt stemmed from this belief, and the same moral reasoning can be observed in his offer to help set a trap on Vendaxa, in order to prevent what he considered to be further and worse atrocities.
After Cade Skywalker's capture by the Sith, Rus was present, via holographic projection, at a Moff Council meeting where Darth Maladi instructed the Moffs to discontinue the search for Cade Skywalker. Following Maladi's transmission, Moff Geist, the leader of the Imperial Army and one of the most militaristic members of the Council, accused Rus of being a spy for Roan Fel.
Following Emperor Krayt's death during the Battle on Had Abbadon, his lieutenant Darth Wyyrlok informed the Moffs that he would be taking control of the Empire until Darth Krayt - whom he falsely claimed was still alive - recovered. After Admiral Veed's promotion to Regent, Wyyrlok requested a meeting with Rus. Wyyrlok informed Rus that the Victory Without War program would be discontinued and that the Imperial Mission would now teach the galaxy Sith values, as well as the Sith Code, in order to unite the galaxy under the banner of the One Sith. Rus was shocked by this news, as he had an agreement with Darth Krayt that would allow the Mission to continue its work unchanged. Rus requested a meeting with the Dark Lord. However, Wyyrlok informed Rus that meeting Darth Krayt would be impossible and that Rus would be receiving Sith instruction personally.
Rus was also physically present at a Moff Council meeting where Morlish Veed, the newly appointed Imperial Regent, announced his plan to capture Roan Fel at a secret meeting between the deposed Emperor and representatives of the Jedi Order on the planet Agamar. Veed also revealed that he had discovered a spy within Imperial ranks, and as a result, no message would leave Coruscant, or any Imperial ship, without his direct approval.
By the time Darth Krayt returned to power in 138 ABY, it was reported that Konrad Rus had disappeared.
Konrad Rus was undeniably devoted to the Imperial Mission and its humanitarian goals, embodying the principles of the Victory Without War program initiated by Jagged Fel. Astraal Vao described him as the embodiment of the Imperial Mission's values. His actions, coupled with his aversion to torture and bloodshed, earned him the admiration of like-minded individuals and the Missionaries who served under him. However, Rus also faced the contempt of more conservative, hard-line members of the Imperial Military, such as Moff Geist.
Rus was also a skilled politician and negotiator. His talent for manipulation garnered him the respect of Darth Krayt, even though Rus's primary goal was to avoid unnecessary bloodshed. Rus understood that in order for the Mission to continue assisting the most vulnerable members of galactic society, he would have to tolerate the ruthless and violent Sith, despite their representing the antithesis of the Mission's values.
Artist Jan Duursema modeled Konrad Rus's appearance after actor Henry Gibson, who is best known for his roles on Rowan & Martin's Laugh-In and as the leader of the Illinois Nazis in The Blues Brothers.
