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.

In 2375, Hrevet was a Commander in Starfleet Intelligence. She and her team were en route to Starbase 585 aboard the USS da Vinci when she learned Donovan had crashed a Breen scout ship with a prototype encryption device on planet Lamenda Prime. She and her team were assigned to recover the device; however, after being attacked by Breen soldiers, she was forced to destroy the ship. (short story: "Field Expediency")
