Trenigar was a male Nausicaan and an associate of the Orion Syndicate, under the command of Ihazs. By 2379, Trenigar served as the master of the freighter Caedera. Trenigar insisted on keeping the ship warm - going so far as to disintegrate a crewmember who had suggested lowering the temperature on the bridge. Trenigar also insisted on wiping transporter and communications records before entering a port. Trenigar also refused to pay for sound dampening equipment for the ship's engineering section.
