This figure made an otter-skin bag after killing the brother of Regin and Andvari in one story, which also sees him warn Hreidmar about a cursed ring.  He distracted Svadilfari to prevent a frost giant from finishing the walls of Asgard on time in another story.  That story sees this god give birth to Sleipnir while in the form of a mare.  In another story Skadi set a serpent above this god after he was bound with the entrails of his son Nari for disguising himself as the giantess PÃ¶kk.  This god gave a spear with mistletoe on the end of it to the blind god Hodr, leading to the death of Baldr.  For 10 points, name this father of Hel, Fenrir, and Jormungandr, the Norse trickster god
