Eponymous ancestor of the Vǫlsungar. Son of Rerir and grandson-line of Odin through Sigi; father of the twins Sigmund and Signý and of eight further sons. His hall is built around the tree Barnstokkr, into which Odin later thrusts the sword Sigmund alone can draw. Killed by his son-in-law Siggeir, setting in motion the cycle of vengeance that defines the line.
