Vuraj Marn functioned as a resistance fighter hailing from Brosi and held membership within the Brosin Underground.
Marn, a devoted subordinate of Randle Clanse who spearheaded the Brosin Underground, commanded the most substantial of the four squads within the Brosin Underground, presumably encompassing over thirty individuals. Operating within the Reyno and Nihun valleys, Marn's unit endeavored to disrupt the industrial endeavors of the Corporate Sector Authority on Brosi, with a specific focus on the Zinsian processing facilities.
The effectiveness of the Underground instilled apprehension within the Rebel Alliance regarding the potential escalation of security measures by the CSA, which could have resulted in the exposure of clandestine Rebel operatives or a Rebel cell consisting of ten members, led by Abil Vilorin. As of 2 ABY, Vilorin faced significant obstacles in his attempts to establish communication with Marn. Even under those circumstances, Vilorin questioned his capacity to genuinely persuade Marn to alter the Underground's strategies.
