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.
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.
