Helgardh

Helgardh (also known as Hel, confusing because since there is a goddess of the same name) as Hel) ("house of mists") in Norse mythology is one of the nine worlds, the abode of the dead, ruled over by Hel. Niflheim is cold and low on the overall order of the universe. It lies beneath Yggdrasil's third root, near Hvergelmir and Nastrond.
