Kicking off a few weeks of adventure in which Thor and Odin visit the battle plain of Vigrid, fated location of the Ragnarok final battle, and discover not all is what it should be.

Vafthruthnir spake:

17. “Speak forth now, Gagnrath, | if there from the floor
Thou wouldst thy wisdom make known:
What name has the field | where in fight shall meet
Surt and the gracious gods?”

Othin spake:

18. “Vigrith is the field | where in fight shall meet
Surt and the gracious gods;
A hundred miles | each way does it measure.
And so are its boundaries set.”
