Ragnarök
There are some beings whose fate after Ragnarok is uncertain. Nidhhoggr is stated to fly with darkness under him and corpses on his back at the end of the Voluspa. This has been noted to not fit well with the theme of the last stanza, in which all of the old and bad has been burnt, and a new world with only good will rise of the waters. The last stanza has seen this interpreted differently, with some having Nidhoggr as the last remaining evil in the new world, and others stating that Nidhhoggr will rise one more time but then fall back to the ground, meaning evil has been defeated and all is good in the new world.
