Mesa Greenbark was a female Nosaurian who married Bomo Greenbark, a commander of the New Plympto resistance who fought against the Galactic Empire. With Bomo, she had had a daughter who they named Resa and after the declaration of the New Order, the political regime of the Empire, she and her child attempted to evacuate their homeworld to escape Imperial forces. While her husband and the rest of the resistance fought one final battle at Half-Axe Pass, Mesa and Resa attempted to reach a spaceport in an area called Cadgel Meadows, but were captured by Imperials before reaching their destination. The evacuees were enslaved and taken to the planet Orvax IV where Mesa was killed attempting to prevent her daughter being sold.
