Step 2 of 12 · The Making of the Worlds
Niflheim (Niflheimr)
Why this step
Niflheimr, the World of Mist, is the cold side. Gylfaginning says it was formed many ages before the earth, with the spring Hvergelmir in its middle and twelve rivers flowing out of it. The entry adds a caution: the name survives in only two sources, and the Poetic Edda mentions Hel but not Niflheim, so the cold world of the beginning rests mostly on Snorri.
