Cool, but
such things as angel wings dont really fit into somthing like valhalla.
it's really cool after all. Been through some mythology stuff? ;)
and azgar is written wrong... it's asgard... actualy "Asgård" but still.. it works.
after what i know, valhalla would have more people around, a larger castle.. and was only made out of wood, copper and very few rocks... with people fighting outside (since if you died in valhalla outside you would revive inside the castle again)
you see.. i know all that because i'm danish..
quite an epic story, i like it though. but try to reduce the use of angel wings and magic :) (only the gods could use such miracles) that feels too, well christian and medieval like. And there was no knights at the time of the mythology :)
told to be happened about 2000 years b.c. (still.. joust a myth though some embrace it as a religion)
if you are about to make a new one.. try use some like, Loke, (could be the evil guy in the end of the flash) and the saxon.. this mythology is epic and if anyone knows how the story of valhalla is, this could be quite.. uuhm.. annoying.. if you know what i mean.
that's all good luck :)
