Definition:
Niflheim (Niflheimr) is one of the nine worlds mentioned in Norse mythology. It is a realm of cold, possibly the location of Hel's realm. Warriors went to Valhalla, while those who died of old age and illness went to Niflheim.
Niflheim is the lowest of the worlds, beneath the third root of Yggdrasil.
