A magical sword, Balmung, was made by Wayland the Smith . Odin stabbed the Branstock tree, an oak tree in the Volsung palace , with Balmung. Odin then said that he who could pull the sword from the tree is destined to win in battle. Nine of the Volsung princes tried to take the sword, but only the youngest ever got it out. His name was Sigmund. Odin destroyed Balmung in battle but it was reassembled and Siegfried used it against Fafnir.
