Only the dragon Nidhogg and his accompanying nest of reptiles can abide the frozen environment in their eternal guardianship of the spring and the gates of Helheim. Nifelheim is so frozen and inhospitable that not even the frost giants live here. The droplets from the ice brought into being all that lives in the nine realms. This vast stretch of ice came ever closer to fiery Muspelheim until eventually, the ice began to melt. Throughout the eons the rivers of Niflheim poured into the abyss, slowly filling Ginnungagap, and forming an endless plain of ice. The spring itself is the source of all life, and it is the place to which all life will ultimately return at the end of ages. The mouth of Helheim is said to be nearby as the dragon also acts as sentry here, preventing the dead from leaving their home to enter the worlds of the living. Nidhogg the dragon, lies next to the spring, guarding it with his host of serpents. These twelve streams later conjoin together to form the rivers Elivagar and Gjol. The spring Hvergelmer, ‘bubbling, boiling spring’, runs through Niflheim, dividing itself into twelve icy streams.
It is a place of darkness, opposite in everything to Muspelheim to the south. Niflheim, ‘mist-home’, ‘mist-world’, also called Niflhel, is an endless expanse of frost, ice, snow, and mist that lies to the north of Ginnungagap. Niflheim – Realm of Frost, Ice, Snow, and Mist.
