Gríðr

"Greed." A giantess who became by Odin the mother of Víðarr the Silent. On his way to Geirröðr's stronghold, Thor spends the night with her and she warns him about the giant's intentions, saying that he was a crafty giant and ill to deal with. She lends him the girdle of might and iron gloves which she possessed, as well as her own staff, which was called Gríðarvölr.

Gríðr is found in the list of troll-wives in the Nafnaþulur section of Skáldskaparmál.
