Egdon Heath is the fictional part of Wessex (also fictional) in which The Return of the Native takes place. It is a large, uninhabited expanse covered with gorse and heather and few trees. The heath, which Hardy describes as isolated and lonely, resists civilization and is the dwelling place instead of the natural and the Celtic, pagan history of England. Edgon Heath has a way of resisting outside forces and keeping its inhabitants from leaving.
Eustacia Vye is a native of the heath but yearns only to escape it. However, in the end, she cannot escape, which shows the power of the heath over people. In many ways, Eustacia is like the heath, as she is described as a kind of goddess drawing her beauty from nature. Like the heath, she is dark and isolated, as she does not connect well to the people around her. The heath functions as a kind of natural parallel of Eustacia and her inner darkness. While she detests the heath, Eustacia is very much like it.
