Norse mythology isn't nearly as bright and cheery as it's shown in the recent Marvel movies. Sure, most people have at least heard of Ragnarok, the great end of all things, and people know that it involves fire and a lot of death. But there are many more Norse myths that are often disturbing, disgusting, and sometimes downright funny. And yes, before you ask, Loki is involved in most of them.
You see, the gods in ancient Norse myths had one thing in common with the Greek gods: they were fallible and totally capable of messing things up. They drank too much, they slept around, they messed with mortals just for fun, they ended up getting a lot of people killed... ok, so they had a lot in common with the Greek gods.
So, prepare yourself for strange monsters, weird punishments, a world made of body parts, and trickery the likes of which you've never seen. Get excited, because it's about to get weird, Norse-style.
