Loki and Fenris ride a boat made of dead men's finger nails. Impending doom builds as the battle approaches.
Voluspa - Norse Mythology Book - Verse 51
“O’er the sea from the north | there sails a ship
With the people of Hel, | at the helm stands Loki;
After the wolf | do wild men follow,
And with them the brother | of Byleist goes.”
