"there was another wolf, a twin to the one that Wednesday was riding"

The twin wolves are Geri and Freki, said to accompany Odin like his ravens.



Another pair of wolves are the offspring of Fenrir: Skoll and Hati, sibling wolves who chase the chariots of the sun and the moon and will one day catch up with them and devour them, heralding the end of the world and Odin's doom.
