Things begin to grow dark as the last battle looms. Odin consults Mimir's head for wisdom, but the shadow of the wolf overhangs his destiny.

Voluspa - Norse Mythology Book - Verse 47

“Yggdrasil shakes, |  and shiver on high

The ancient limbs, |  and the giant is loose;

To the head of Mim |  does Othin give heed,

But the kinsman of Surt |  shall slay him soon.”

Bellows Translation
