Svanhildr

Svanhildr is the beautiful daughter of Sigurðr and Guðrún in Germanic heroic legend, whose grisly death at the hands of her jealous royal husband Jǫrmunrekr was told in many northern European stories, including the Old Norse Poetic Edda (Hamðismál and Guðrúnarhvǫt), Prose Edda, and Vǫlsunga saga; the skaldic poem Ragnarsdrápa; the Danish Latin Gesta Danorum; and the German Latin Annals of Quedlinburg.

Plot
Svanhildr was "the most beautiful of all women," and was married to Jǫrmunrekr the king of the Goths. She was accused of infidelity with the king's son, Randver. Because of this Ermanaric had her trampled to death under horses.

Svanhildr mother, Guðrún, made her half-brothers Hamdir and Sǫrli exact revenge for her death.
