You are a normal person in a normal world. Until the Norse myths come true and the end of the world begins. Will you fight for the good? The bad? Or will you do all you can to survive until it's over?

So, im writing a story about Ragnorak, so if anyone does know anything about Norse Mythology/Ragnorak I'd really appreciate some cool ideas to add into the story. It's going to be based in a modern setting where you see the fire giant while in a plane and  was planning to have it so you could join either side. Thanks for any help in advamce!
