Narfi

Narfi (Nörvi or Nor) was the son of Loki and Sigyn, he was the brother of Vali and father of Nott (the night).

Vali was changed into a wolf (by the gods) and torned Loki's son Narfi to pieces. Then the gods took bound Loki to a rick with Narfi's bowels.

According to the Poetic Edda, the gods turned Narfi into a wolf and Vali was torned to pieces.

One of Saturn's moon has the name Narvi.
