Norvalen homeworld
The Norvalen homeworld was an inhabited planet in the Delta Quadrant. It was the homeworld of the spacefaring Norvalens.
According to Jaffen, a native of this world, it could be described as overpopulated, pollution, and lacking work, much like Earth (according to Kathryn Janeway's description). A small number of Norvalens left the planet looking for work elsewhere. (VOY: "Workforce")
This planet was only mentioned in dialogue.
