گریم‌هیلد

In Norse mythology, Grimhild or Grímhildr ("masked battle") was a beautiful but evil sorceress who was married to king Gjúki of Burgundy in the Völsunga saga where she is the mother of three sons, Gunnar, Hǫgni and Guthormr, and a daughter, Gudrun. Other, similar characters of that name also appear in Illuga saga Gríðarfóstr and in Gríms saga loðinkinna.
