Mime is the younger brother of Alberich, and a master forger. Completely subservient to his brother, he was forced to create the Ring of the Nibelungen out of the Rhinegold. Later, he became the foster-father to the hero Siegfried, all the while keeping him ignorant of his true parentage. After Siegfried reforged the sword Nothung - an act that Mime could not accomplish - Mime became fearful and tried to poison his ward. However, Siegfried read his thoughts and killed him with Nothung.
