Götterdämmerung
Act One takes place in the Hall of the Gibichung palace. Gunther is the chief of the Gibichungs. His half-brother Hagen tells him he would look more important if he got married. He also says that Gunther’s sister Gutrune ought to get married. He tells him about Brünnhilde who, he thinks, is still asleep on the rock surrounded by fire that no one except Siegfried would be able to get through. He says that if they manage to get Siegfried to marry Gutrune, then she could persuade him to go and catch Brünnhilde for Gunther. He says that they could give Siegfried a potion (a special drink) which would make him forget that he loved Brünnhilde.
