Now, as a member of S.I.N, I'm an atheist. However, Norse mythology greatly interests me, because, for a polytheistic belief system, it is very well thought-out. I mean, they even developed a system of cosmology, a universal geography, if you will, of their universe. The example wikipedia has of the nine worlds shows this:
And, above all, the norse gods are gods that people could easily identify with. They are honorable usually, but often succumb to thier emotions. They have flaws, like mortals do. Frick, they can even die, like mortals do. The norse gods are gods one could kinda understand and be on the same page with, along with the greek pantheon.
Plus, Valhalla owns as a heaven. I mean, the schedule of life in valhalla is this: gorge yourself' on mead and meat till you are stuffed, then fight to the death and respawn back at the mess hall. Repeat process until the world ends. That is an awesome afterlife.
So, let us discuss the pros and cons, the interesting and boring bits, and the weirdness and coolness of Norse Mythology.
