In 2152, T'Pol contacted Trellit for assistance when Captain Jonathan Archer and Commander Tucker vanished while visiting the officially outlawed Zobral. Trellit proved to be of little help, as Zobral was the leader of a faction opposing the ruling caste of Toroth. (ENT: "Desert Crossing") Trellit was played by actor Charles Dennis. In the final draft script of "Desert Crossing", Trellit was described as "a terse and unceremonious City Official [...] wearing a distinctive uniform." The character was thereafter referred to in the script as "City Official", even after giving his name.
