Weird how there isn't any concept art for Niflheim, aka, the place where Hela was vanished... I wush there were art of it though, since it is the second shadowy area around the Nine Realms outside of Svartalfheim, the home of the Dark Elves... and if you squint it, Jotunheim which is the home of the Forst Giants, and it is known as a place of cold and darkness...
