Dantalian is a dark priestess that is a high-ranking evil dignitary with the dangerous ability to shield her activities from the forces of good. She possessed great magical skill and power, as well as the ability to teleport. For a short time, she was able to steal and wield the Halliwell Book Of Shadows, but the sisters were able to break the Unholy Union she had created between Prue and Zile, returning the book to good. The Charmed Ones vanquished Dantalion.
