Tev Nallor was a male Heiren who served as second-in-command to Heir'at's Second Minister of Security, Ar Bintor, in the early 2250s.

In 2251, Nallor was charged with accompanying Heir'och telepath, Perris Nodarh, to the Eastern Temple of the city so that the reconciliation ceremony between the Heir'och and the Heir'tza could take place. Unfortunately enroute to the temple, Nallor was attacked and murdered by six Heiren kidnappers, who then made off with Nodarh. Fortunately, Nodarh was later rescued by Starfleet cadets, James T. Kirk and Gary Mitchell. (TOS - My Brother's Keeper novel: Republic)
