Cordelia is a member of Ylisse's Pegasus Knights, and is a childhood friend of Sumia. Her duty is to protect the royal family, though she also guides Sumia when the latter is in trouble. She rides a pegasus named Aurora. During her days as a recruit, it was apparent that she was a prodigy in nearly everything she attempted to do, except running. It was her lack of running skill that led her to the squad in the first place. Eventually she would enter the Pegasus Knight squad as an official member, though she was heavily hazed.
