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.”

Bellows Translation
