In the ancient Norse Volsunga Saga, the sword Gram first appears as a gift from Odin, offered to the first Viking who can pull it from the trunk of the mighty Barnstokkr tree. Extracted by the warrior Sigmund, the supernaturally sharp sword leads a storied existence, as does he. Sigmund proves to be less than honorable, however. When his lands are attacked by King Lyngi and his army, a disguised Odin confronts him during the melee and breaks the sword, and allows him to be killed in the battle.
