Grafvitner the Gnawing Wolf is a linnorm who bites at the roots of the world tree Yggdrasil.

Grafvitner is father to the linnorms Goin and Moin.[1]

Creative origins[]

Grafvitner, or Grafvitnir, originates in Norse mythlogy. It is described in stanza 43 of Grímnismál as an ormr or wyrm. The meaning of its name is "the gnawing wolf". It is not referenced in any other known works, and stanza 43 is thought by some scholars to be a later addition to the original text.[2]
