Vethrfolnir

In Norse mythology, Yggdrasil is the world-tree that connects the nine Worlds. Atop the tree perches the Unnamed Eagle, and between his eyes sits its hawk companion, Vethrfolnir.

In the game, the duo is seen during the level Vethrfolnir's Perch, where they serve as the level's hazard. The Unnamed Eagle is many times the size of a man and will fiercely defend its nest, commonly trying to swoop down upon Thora with its deadly claws. Quick reflexes are required to dodge the eagle's swoop, denoted by a dark shadow where it will land.
