Valkyrie

The Valkyrie are the children of Wotan and Erda. Their leader is Brünnhilde, and they sing one of the most famous arias in all of opera, the Ride of the Valkyries. Their role is to take dead warriors to Valhalla for its protection. Preseumably they perish with the other Gods when Valhalla is set alight at the end of Gotterdammerung.
