Enid appears in the story, Gereint Son of Erbin. She is the beautiful, hard-working daughter of an impoverished earl, who marries Gereint. Completely loyal to her husband, Enid is a faithful wife, who never betrays him, even when tempted by two earls. Although, she doubts her husband's prowess and often acts impulsively out of concern for his well-being, she trusts him completely.
