Dahlia (Elder Futhark: ᛞᚨᚺᛚᛁᚨ) was "one of the most powerful witches in history"[1] and the main antagonist of the second season of The Originals. She was the older sister of Esther, the sister-in-law of Mikael, the maternal aunt of Freya, Finn, Elijah, Niklaus, Kol, Rebekah and Henrik Mikaelson, and also the great-aunt of Freya's deceased unborn son and Hope Mikaelson.

Described by Freya as the most powerful witch she has ever seen, Dahlia first gained her enhanced powers by linking her magic.
