Thrello Zirt

Thrello Zirt was an El-Aurian scientist, professor and lecturer--a short, full-bodied man with a flashy smile and great showmanship. He clashed with Tolian Soran over the meaning of scientific data pertaining to the Nexus, going so far as to humiliate Soran publicly before the entire El-Aurian scientific community. Years later, the disgrace helped to compel Soran's quest to enter the Nexus. (Star Trek: Arcadia)
