Grettir the Strong challenges men like Atli of Birag to a “fight” among these beings at Longfit in chapter 29 of his saga. While traveling to bargain for Baldr’s return, one of these beings helps Hermod to get over the gates of Hel. After he lifts Hrungir’s massive leg, a three-year old Magni is given one of these beings by his father Thor. The Grímnismál (15[1])and Gylfaginning include (*) lists of these creatures owned by the Aesir, including ones named Falhofnir and Gulltoppr. The jotunn who built the walls of Asgard (10[1])was helped (10[1])by one of these creatures (10[1])named Svaðilfari (“SVAH-theel-FAH-ree”). Skoll chases two of these creatures who pull the sun across the sky. For 10 points, name these creatures such as Loki’s child Sleipnir (“SLAYP-neer”), who is ridden by Odin. ■END■
