Skoll

Skǫll (meaning "treachery" in Old Norse) was a wolf in Norse mythology. The son of Fenrir and Hyrrokkin, Sköll chases Sól through the sky and will devour her and her horses at Ragnarök. Sköll's brother Hati chases Sól's brother Máni and will devour him at Ragnarök also.

One of Saturn's moons is named after him.
