Wagner made a lot of changes to the story in order to make it suitable for his four operas. Wagner’s story tells of a hoard of gold which is being guarded by the Rhinemaidens. The dwarf Alberich steals the gold and uses some of it to make a ring which makes the owner powerful over all the world. When Wotan, the chief god, steals it from him, Alberich puts a curse on the ring. The ring will bring death to whoever has it. The ring goes through the hands of several characters, all of whom die in the end.
