Brief Bio

Niflheim is a primordial realm of mist, fog, and cold in Norse mythology, considered the abode of the dead who died from sickness or old age. It is characterized by freezing temperatures, icy landscapes, and rivers like Hvergelmir. Niflheim served as a contrasting force to the fiery realm of Muspelheim, with the two realms' interaction helping to form the world.

Between these two realms of cold and heat, creation began when its waters mixed with the heat of Muspelheim to form a "creating steam". 

Later, it became the abode of Hel, a goddess daughter of Loki, and the afterlife for her subjects, those who did not die a heroic or notable death.
