The Nargons were a biotically created species of humanoids with prehensile tails and lizard-like features. They fought for the Columi brothers, Craitheus and Marvid Qreph, who had created them. They aided the brothers in taking over the Chiloon Rift and were placed under the command of Mirta Gev's Mandalorian forces. A large number of them were killed in missions for the Columi, with the majority wiped out during the Assault on Base Prime.
