After throwing one of these objects named Sviagriss on the ground, King Hrolfr declares Eadgil no better than a pig for bending over to pick it up. One of these objects wrapped in wolf’s hair warns a Burgundian king about the treachery of Atli the Hun. A cursed one of these objects is found alongside the Helm of Terror and Hrotti in a treasure hoard. Loki completes a wergild that he owes to Hreidmar by placing one of these objects (15[1])upon an exposed whisker of an (*) otter’s pelt. That one of these objects named Andvaranaut turns one owner into a creature whose blood (10[1])grants the ability to understand the language of birds. (-5[1])Odin owns one of these (10[1])objects that creates eight copies of itself each night, named Draupnir. For 10 points, name these objects, one of which turns Fafnir into a dragon and titles an operatic cycle by Richard Wagner ■END■ (10[1])
