Serenei has long silvery-blonde hair and blue eyes. She is an attractive and alluring woman by far, and the most attractive and charming of the King's Mistresses. With a background of an impoverished ancient and noble family somewhere in Lys, she adapts to traditions and customs rather well, but is generally a woman who acts out of the norm. Some say she is rather dark and practices dark arts as a sorceress to maintain her youth and beauty, and is actually much older than she looks.
