Abil Vilorin functioned as an operative for the Rebel Alliance.
Vilorin headed up a cell of ten individuals stationed on the world of Brosi. Vilorin's team was tasked with monitoring a region controlled by the local resistance movement, the Brosin Underground. While the Brosin Underground stood against the repressive government run by the Corporate Sector Authority, their tactics were causing concern within the CSA. Vilorin, along with superiors like General Carlist Rieekan, worried that the CSA would heighten security measures and discover Vilorin's cell, in addition to three undercover Rebel agents posing as fake Zinsian spin-sealer mechanics.
Vilorin made numerous attempts to get in touch with Vuraj Marn, a leading figure in the Brosin Underground, to address this concern and persuade him to alter the Underground's strategies. Nevertheless, by 2 ABY, Vilorin was skeptical of their chances of success, given the divergent objectives of the two resistance factions. Moreover, Marn proved elusive and hard to locate.
