Æsir
Váli
Odin's son by Rindr, born to avenge Baldr: at one night old, unwashed and uncombed, he killed Baldr's slayer Höðr. He survives Ragnarök.
Váli exists to avenge Baldr. When Odin rode to the underworld in Baldrs draumar to ask who would avenge his son, the dead seeress answered: "Rind bears Vali in Vestrsalir, and one night old fights Othin's son". He would not wash his hands or comb his hair "till the slayer of Baldr he brings to the flames" Baldrs draumar 11. Völuspá repeats the image, calling him only "the brother of Baldr" Völuspá 33 Völuspá 34, and Hyndluljóð says that Váli "was swift, when his brother's slayer soon he slew" Hyndluljóð 30.
The slayer was the blind god Höðr, also Odin's son. Váli is thus a son born to kill a brother for the death of a brother, which shows the duty of blood-vengeance working even inside the gods' own family. Snorri's kennings call him "Baldr's Avenger, Foe and Slayer of Hödr" and "Stepson of Frigg" Skáldskaparmál 12. His mother is Rindr Gylfaginning 30.
Snorri's own description is brief: Váli, also called Áli, is "daring in fights, and a most fortunate marksman" Gylfaginning 30. He is among the twelve gods who sit as judges when Ægir visits Ásgard Skáldskaparmál 1.
Váli is one of the few gods who outlive Ragnarök. "In the gods' home Vithar and Vali shall dwell, when the fires of Surt have sunk" Vafþrúðnismál 51; Snorri adds that neither sea nor fire harmed them Gylfaginning 53.

Rind bears Vali in Vestrsalir, And one night old fights Othin's son; His hands he shall wash not, his hair he shall comb not, Till the slayer of Baldr he brings to the flames.
But the brother of Baldr was born ere long, And one night old fought Othin's son.
One is called Áli or Váli, son of Odin and Rindr: he is daring in fights, and a most fortunate marksman.
In the gods' home Vithar and Vali shall dwell, When the fires of Surt have sunk
Where the sources disagree or fall silent
- Snorri says the gods turned Loki's son Váli into a wolf, which tore apart his brother Narfi, whose guts were used to bind Loki (Gylfaginning 50). The prose at the end of Lokasenna says the reverse: Loki was bound with the bowels of his son Vali, and Narfi became the wolf (Lokasenna, prose 7). This Váli, son of Loki, is a different figure from Odin's son.
