Niflheim is one of the primordial worlds and is a land of Mist and Ice. Niflheim is at the furthest, northern reaches of the frozen North Sea. Hel rules Niflheim and she subjugates all those how did not die a heroic death. To pass through the land you must answer three riddles posed by Hel herself, but if you answer incorrectly, she will throw you into the river of death. Upon answering each question, Hel allows you to pass. Finally, you will find yourself before the Gjoll River and you may cross the bridge and enter Helheim. Any living soul, who enters Helheim, may never leave.
