Niflheim (pronounced "NIF-el-hame") is one of the Nine Worlds, more specifically the primordial world of ice and frost.


Niflheim is described as an inhospitable, frigid region of ice, frost and mist. High summer temperatures are around thirty degrees below zero Fahrenheit.

  • If locations have Greco-Roman equivalents, Niflheim could be compared to Hyperborea, being lands of Frost Giants in perpetual sunshine.
