avenged. She sent her elder son to Sigmund for him to help in this endeavor. When Sigmund revealed to her that he was unworthy, Signy told Sigmund to kill him, which he did. The same happened with her younger son. Signy met a sorceress with whom she exchanged shapes. Signy, looking like the sorceress, went to her brother in the woods and slept with him for three nights. She then returned to the castle and regained her appearance. After a time she gave birth to a son Sinfjötli. He was also sent to her brother in the forest when he was nine years old. Sigmund and Sinfjötli kill Siggeir to avenge the death of their father/grandfather together. It is only after this that Signy informs Sigmund of the incest that led to Sinfjötli's birth. Signy then walks into the fire that is killing her husband, announcing, "In everything I have worked toward the killing of King Siggeir. I have worked so hard to bring about vengeance that I am by no means fit to live. Willingly I will now die with King Siggeir, although I married him reluctantly."
