"Rumours of Götterdämmerung were sweeping the white suburbs"

Götterdämmerung (Twilight of the Gods) is the last in Richard Wagner’s cycle of four operas titled Der Ring des Nibelungen. The title is a translation into German of the Old Norse phrase Ragnarök, which in Norse mythology refers to a prophesied war of the gods that brings about the end of the world. 

The term Götterdämmerung is occasionally used in English to refer to a disastrous conclusion of events.
