I don't know if anyone noticed, but Nidavellir in Grizzleheim is actually one of the 9 worlds in Norse mythology. I think it was supposed to be like the underworld or something, I know it was supposed to be the home of the dwarfs. I doubt anyone cares, but I thought I'd mention it. And I was wondering about that tree that holds the spiral door in Grizzleheim, is it supposed to be like Yggdrasil or something? It looks special, and it's different than spiral doors in other worlds.
