A Human male named Milosh Muhrlein lived a life of service to both the Galactic Republic and, subsequently, the Galactic Empire. He achieved the rank of colonel within the Empire's structure, and was designated as the leader of Imperial Research Station 61 located on the planet of Wayland. To sustain a lavish lifestyle beyond his official means, he engaged in the practice of illicitly selling technology developed by his station's staff on the black market. These clandestine activities of Muhrlein were eventually discovered by Imperial Intelligence Agent Jahan Cross, whom Muhrlein then attempted to silence through bribery. Failing in his attempt to bribe Cross, Muhrlein resorted to trying to kill him, but this effort also failed, resulting in Muhrlein's own death.
Born into a wealthy family, Milosh Muhrlein was a Human male who initially served the Galactic Republic during the Clone Wars against the Confederacy of Independent Systems. Following the conclusion of the Clone Wars in 19 BBY, Muhrlein transitioned his service to the Galactic Empire, the successor to the Republic, ultimately rising to the rank of colonel. By 3 BBY, he was given command of Imperial Research Station 61 on Wayland in the Mid Rim. However, his family's fortune had been depleted by this time, making it impossible for him to maintain the opulent lifestyle he craved. To supplement his income, Muhrlein secretly began selling experimental technology and droid protocols from the station on the black market, dealing with entities such as Hutts, smugglers, and Rossum Droidworks. Rossum Droidworks, in particular, were significant clients, gifting him an Orchard vine and Novanian grog from the Corporate Sector as a token of appreciation for the supplies he provided for their Iron Eclipse computer virus project. To safeguard against potential intruders who might uncover his illicit activities, Muhrlein had B-2A and B-2B, two of the station's latest experimental battle droid models, installed within the walls of his office.
In 3 BBY, Jahan Cross, an envoy from the Imperial Diplomatic Corps and an agent of Imperial Intelligence, was discovered by Muhrlein searching through the station's files in his office, aided by the Human replica droid IN-GA 44. Despite Muhrlein's objections, Cross persisted and accused the colonel of selling station property on the black market, citing evidence from the files and the gifts from Rossum Droidworks, which were beyond the commandant's financial means. Muhrlein's attempt to bribe the agent failed, leading him to order his battle droids to attack. IN-GA 44 neutralized the droids, while Muhrlein attempted to shoot Cross, who defended himself with an advanced Verpine force field. Cross circumvented the field using devices concealed in his boots, which released a powerful electrical surge that killed Muhrlein. Despite complaints from Muhrlein's family and friends in Imperial Court following his death, Cross initiated an investigation into the Iron Eclipse project based on the information he found in Muhrlein's files.
Milosh Muhrlein possessed fair skin and blue eyes. By the end of his life, he had become accustomed to a luxurious lifestyle and was prepared to betray the Empire in order to maintain it. Muhrlein was forward-thinking enough to implement several defensive measures in case his treachery was uncovered. When his deception was exposed, he tried to use bribes to save himself and viewed Agent Cross as a fool for adhering to principles and refusing the bribe. While serving as commandant, Muhrlein had gray hair.
During his time as commandant, Muhrlein wore a standard Imperial officer's uniform and a sophisticated force field developed by the Verpine species. He had a collection of blasters displayed on his wall, and he carried one for personal protection in addition to his two battle droids.
Milosh Muhrlein's first appearance was in the comic-book Agent of the Empire – Iron Eclipse 1, written by John Ostrander as part of the "Iron Eclipse" story arc of the Star Wars: Agent of the Empire series, which was released on December 14, 2011. The character was illustrated by Stéphane Roux.
