Dernovin

Dernovin was a planet in the Delta Quadrant, and the seat of an interstellar empire.

In the 23rd century, Dernovin annexed the planet Draanis IV, and made its inhabitants, the descendants of a crashed Trevin spacecraft, slave laborers.

In the 24th century, a group calling themselves the Trevin Resistance Movement captured the USS Voyager and used it to destroy to the city of Gortella. Dernovin retaliated by exterminating the population of Draanis IV. (VOY short story: "Fiction")
