But the real avenger is Signy, the daughter of the dead King Volsung and the wife of the murderer. Signy knows that her brother Sigmund is alive. But that makes only two Volsungs; and two young people alone cannot hope to destroy a king and an army. But Signy believes that three can do it. Secretly she keeps her brother supplied with provisions and weapons, and she resolves to raise up sons to avenge the wrong. When her first son is born she begs to train him, and when he is old enough to begin to learn what war means, she sends him to her brother in the wood that he may teach the lad. Sigmund does not much like the boy. He thinks that he talks too much to be really brave. He tests the lad's courage in different ways, telling him, among other things, to bake and knead cake in which a poisonous snake has been hidden. The boy is afraid of the snake. Sigmund sends him back to Signy, saying that he will not do. Signy almost despairs. Must her sons be cowards because they have a coward father? Suddenly a strange idea comes to her. "I shall do as the Gods did in ancient times," she said; "only my brother can produce such a child as I wish for, and I shall have a child by him." She goes to a witch, who changes her body, transforms her so completely that her brother can have no suspicion of what has taken place. Then by him she has a son, Sinfiotli. When he is old enough she sends the boy to Sigmund. Sigmund is astonished by the extraordinary fierceness and sullenness of the child. "Is it possible," he wonders, "that my sister can have such a child by her husband?" The boy scarcely speaks at all, but does whatever he is told, and is afraid of nothing. Sigmund gives him flour to knead and bake containing a poisonous snake. Instead of being afraid of the serpent, the child breaks and crushes the creature in his fingers and rolls the poisonous body in the flour, and makes the whole thing into cakes. Sigmund is delighted. He sends word to his sister, "This boy will do." The rest of this part of the story you can imagine. The boy grows up a giant, and is trained in all arts by Sigmund. On a certain day these two unexpectedly force their way into the palace of the King Siggeir, slaughter his people and himself, and set fire to the palace. Thus King Volsung is avenged. But Signy, after having told her brother the story of Sinfiotli, goes back into the burning house of the king, and voluntarily dies. She has done her duty, but she does not care to live any longer. This ends the great episode of the Volsung Saga.
