The chancellor of the ruling Torothan clan, who in 2152 warned Enterprise that Archer's desert host Zobral was a terrorist and then attacked the camp where the captain was staying.
Trelit appears in the first-season Enterprise episode Desert Crossing, played by Charles Dennis. He leads the Torothan government, which Zobral and his followers accuse of keeping their people as a powerless underclass.
While Archer and Tucker are guests at Zobral's desert settlement, Trelit contacts T'Pol aboard Enterprise. He tells her that her captain is in the company of a dangerous insurgent and makes clear that he sees any dealings with Zobral as taking sides.
Torothan forces then bombard the encampment, driving Archer and Tucker out into the desert, where Tucker almost dies of heat exhaustion. Trelit's government also obstructs the search, and the two men have to be rescued by shuttlepod.
