Mercy is a young, beautiful woman with a ready smile and bright blue eyes. She seems a bit shy at first, but when one earns her trust, she has a delightful laugh and easy nature about her. Sworn to the Lady's service, Mercy is no temple servant, but a true priestess of the Lady. She stands about five feet six inches tall and is slender, though not unpleasingly so.

After her ordeal and conversion to a vampire, Mercy is still beautiful, if not more so but spooky. Her hair is jet back and her skin ivory. She avoids the sun though it does not harm her. She is not undead despite having traits of the  vampire like fantastic strength and vitality. Her eyes are blood red in the candlelight.
