Volsung

Volsung was the king of Rijnland in Hunaland and the son of King Rerir (who died before Volsung was born).

Volsung is conceived through the magical intervention of Grimhild, for which he is beholden to the Niflungar.

The Mists of Niflheim
Odin is marching through his lands with the Aesir. Volsung allows this in exchange for tribute. However, Gudrun insists Volsung betray Odin. This leads to a battle in which Volsung is defeated but not killed.

The Shores of Vanaheim
Gudrun returns to Volsung (with Hljod this time) and demands he go after the Aesir again. He reluctantly agrees. During these events he meets Hljod, whom he marries. He leads another ill-fated attack against the Aesir, then retreats when he realizes they cannot win. He and Hljod have a number of children, the first of which are the twins Sigmund and Sieglinde.

The High Seat of Asgard
King Siggeir Wolfsblood comes to Volsung’s hall and asks for Sieglinde’s hand in marriage, which Volsung grants. Several moons later. Volsung goes to Sviarland to visit them. Wolfsblood betrays them and Volsung falls in battle, killed by Starkad Eightarms.
