‘And when these events take place, Heimdall will stand up and
blow mightily on Giallarhorn and awaken all the gods and they
will hold a parliament together. Then Odin will ride to Mimir’s
well and consult Mimir on his own and his people’s behalf. Then
the ash Yggdrasil will shake and nothing will then be unafraid in
heaven or on earth. The Æsir will put on their war gear, and so
will all the Einheriar, and advance on to the field. Odin will ride in
front with golden helmet and fine coat of mail and his spear called
Gungnir. He will make for Fenriswolf, and Thor will advance at
his side and be unable to aid him because he will have his hands
full fighting the Midgard serpent.
