For 10 points, identify this set of four operas by Richard Wagner.
One part of this work contains the often excerpted "Forest Murmurs," and one character in that part exhanges three riddles with the Wanderer. That part opens as that character, Mime, is forging a sword. One of this work's two ensemble pieces comes after its namesakes mock an ugly character who tries to woo them; he then steals what they are guarding. That piece is the song of Woglinde, Wellgunde, and Flosshilde, the Rhinemaidens, and that ugly character is the dwarf Alberich, who has stolen the Rheingold. Ending with the section entitled Twilight of the Gods, its second section contains a piece in which four of Brunnhilde's sisters gather near a mountain, the famous "Ride of the Valkyries."
