Apparently adept at crashing parties, this "13th guest" is able to convince the God of Darkness to shoot the God known as "Balder the Beautiful".
The mistletoe figures also in Scandinavian legend as having furnished the material of the arrow with which Balder (the sun-god) was slain by the blind god Hoder.
Some scholars have thought that Balder, the son of Odin, was once known in Germany, but the evidence is at least doubtful.
Odin's wife was Frigg; their sons were Thor (the thunder-god) and Balder, whose myth is well known in English poetry.
In the German mythology the army of darkness is led by Hel, the personification of twilight, sunk to the goddess who enchains the dead and terrifies the living, and Loki, originally the god of fire, but afterwards "looked upon as the father of the evil powers, who strips the goddess of earth of her adornments, who robs Thor of his fertilizing hammer, and causes the death of Balder the beneficent sun."
