Hmm… So if we can have symbolism surrounding Ragnarök, why not other religions’ end times as well?
For one thing, the Christian Revelation of John has two Beasts – one from the sea (a hydra-like creature, by the sound of it) and one of the earth – ruling Earth under “the Dragon”.
Beyond that, I don’t see that many parallels to the Christian apocalypse just yet, but I’m just bringing up the possibility that we might. Not just Christianity either, but I know very little about most linear religions’ ideas of the end of the world.
Also, one piece of weirdness is that the return of Jesus is supposed to be late in the Christian apocalypse, but the closest we’ve got to a Jesus figure in Worm is Scion, who came at the beginning of what I’ve speculated to be analogous to the end times.
Anyway, in related news, I just read through the Wikipedia article on the events of Revelation, and damn, it’s a complicated apocalypse they’ve got.
