Darva was a resident of Biitu, her homeworld, and a member of the Biituian species. She resided in a village during the initial period of the Galactic Empire's reign.
The arrival of an Imperial starship, carrying the Great Heep to initiate a mining endeavor, prompted her to escape. This escape occurred when the Imperials unleashed a massive storm, tearing apart trees and depleting the local river of its water. The construction of the "moisture eater," a structure designed to extract all humidity from the atmosphere, forced Darva and her people to endure a severe drought, endangering their survival. Ultimately, Mungo Baobab, along with the droids C-3PO and R2-D2, intervened and rescued them from this plight.
Ben Burtt conceived the character of Darva for The Great Heep, a Star Wars Droids television special. Melleny Brown provided the voice for Darva in this special.
