Niflheim is a term derived from Norse mythology, serving as one of the nine worlds or realms within the cosmology of this ancient belief system. It is primarily associated with darkness, cold, and icy landscapes. Niflheim is believed to be the land of mist or fog, with its name translating to "Mist Home" or "Mist World" in Old Norse.
According to Norse mythology, Niflheim stands opposite to Muspelheim, another world characterized by fire and flame. It is depicted as the primordial realm, given birth prior to the creation of the cosmos. Within Niflheim, the primeval wellspring called Hvergelmir exists, which serves as the origin of numerous rivers, including the mythical rivers of Elivágar. These rivers eventually reach the air and form frost and ice.
Niflheim is home to numerous terrifying creatures, such as the primordial beings Ymir and Audumbla, who played pivotal roles in the creation myth. In addition, it is associated with the monstrous serpent Jormungandr, who is said to encircle the entire world of Midgard.
Niflheim is often referred to as the underworld or realm of the dead, as it houses the land of Hel, where those who die of old age or illness are believed to go after death. However, it should be noted that Hel is considered distinct from the concept of the more well-known realm of the dead, Valhalla.
In contemporary contexts, Niflheim is often mentioned in discussions pertaining to Norse mythology, fantasy literature, gaming, and popular culture. Its dark and icy characteristics make it an intriguing and evocative concept within these realms.
