Danica Duana is the daughter of Padraic Duana and Edora Duana, and the sister of Elias Duana. At the start of Reckoning, she is attending Academy with the goal of becoming a White Habit, or doctor. Her father and brother work in the family distillery in Knoll Creek. Her mother passed when she was 10. Though younger than Elias, she humorously refers to him as her "little brother."

She is one of the primary characters throughout the entirety of The Empyrean Chronicle.
