Sinfiötli
Sinfiötli is a mythical figure from the Nordic legends , in this case from the Edda .
He is a son of the twin siblings Sigmund and Signy , thus Wölsung pure blood. His mother is married to King Siggeir of Gautland (possibly Gotland ). He had the whole family of the Wölsungen killed at a feast, only Signy, his wife and her twin brother Siegmund survived the bloody act. When he has reached a suitable age, his mother sends Sinfiötli to his natural father / uncle Sigmund, who lives hidden in the forest. After various adventures in which they turn into werewolves and fulfill their duty of revenge on Siggeir, Sinfiötli and his father return to Hunaland , their home.
Sigmund marries Borghild von Bralund (presumably located in Denmark ) and they have two sons, Helgi and Hamund . Together with Helgi, Sinfiötli goes into battle against the father and fiancé of Sigrun , the lover and later wife Helgis. Soon after he has returned, he sets off again on a new military expedition (other countries are attacked and devastated), where he meets the beautiful Swintha, Queen of Warnen , and wants to take her to his wife. But now Borgar, the brother of his stepmother Borghild, has also cast an eye on the lady. The two rivals go to the spar , with Borgar being killed. On his return, Borghild learns of her brother's death and is of course angry with her stepson. She wants him to leave the country, but Sigmund wants to keep the son with him. He offers his wife Wergeld , whereupon she says that he has to decide, that she wants to come to terms with his decision.
With the consent of her husband, she organizes a funeral feast in memory of Borgar. She herself pours the mead into the horn and offers Sinfiötli the drink. But she poisoned the mead.
Sigmund furiously takes the body of his dead son and carries it through the forest to a bay that he cannot cross. A man comes with a small boat and offers to ferry him over. However, the boat is already full of Sinfiölli's body alone. The boat casts off and soon disappears before Sigmund's eyes. Only then does he notice that Odin himself is bringing his son's body to Valhalla .
When Sigmund returns home, he casts out his wife Borghild, who dies soon after.
