Signy

Signy or Signe (sometimes known as Sieglinde) is the name of two heroines in two connected legends from Scandinavian mythology which were very popular in medieval Scandinavia. Both appear in the Völsunga saga, which was adapted into other works such as Wagner's 'Ring' cycle, including its famous opera The Valkyrie. Signy is also the name of two characters in several other sagas.
