Anyone know any random facts about Gotterdamerung from Wagner's Ring cycle? I'm writing an essay and trying to make it interesting...

"Götterdämmerung is the last in Richard Wagner's cycle of four operas titled Der Ring des Nibelungen (The Ring of the Nibelung). It received its premiere at the Bayreuth Festspielhaus in 1876, as part of the first complete performance of the Ring."
