Possibly in the late 6th century, a being claiming to be the Norse god Odin, disguised as a beggar, plunged a Sword into a tree called Barnstokkr, stating that whomever was able to pull it free would receive it as a gift. Only the warrior Sigmund proved able to do so, and subsequently claimed the Sword as his own.
According to legend, his son Sigurd would later on use his father´s sword to slay the dragon Fafnir.
In 2012, Clay Kaczmarek included Johannes Gehrts' illustration of Sigmund approaching the sword in the tree in a set of puzzles he had hidden within the Animus for his successor, Desmond Miles to find. Desmond did so in September of that year, uncovering Clay's message suggesting that the sword of Sigmund's was in fact a Sword of Eden.
