There is so much viking stuff going on that its just impossible to miss.
Also, Why would you assume that the story needs to fit into any actual religious precepts? There is so much of it out there and so much conspiracy stuff that the major themes associated just jump right out at you. religion, armor of gods, hand to hand combat, the animals thing, the numbes, the stronomy/astrology stuff. come on guys. it doesn;t have to make sense all together.
the point is that if you think of prophecy from every religion then all those themes are present. all of the religions where right and dethklok is the embodyment of doom. The religious people just did not know it was going to be a metal band.
Thats the joke isn't it? that its not horsemen or a nuclear winter brought on from fueding countries, or an asteroid.
IT WAS A METAL BAND get it?
why do you try to put the writers in a tiny little box where all they do is rewrite sumerian scripture?
