Hrevet was a female Bolian in Starfleet in the 24th century. She was a member of Starfleet Intelligence operating largely in Cardassian space during the Cardassian Wars, and later during the Dominion War. As an Ensign early in her career, Hrevet served under Lieutenant Tobias Donovan. Donovan would become a mentor to Hrevet, teaching her survival techniques not learned in training courses.
