Niflheim is one of the Nine Worlds in Norse mythology, a realm of ice and cold located in the northern region. It is said to be the homeland of primordial forces and beings such as the ice giants and the dragon Nidhogg. Niflheim is often associated with the primordial chaos that existed before the creation of the world.
Norse mythology varies with the seasons. For one instance idunn who resembles summer in this myth falls off a branch of Yggdrasil into Niflheim. This causes winter.
Ymir is the primordial giant and father to the frost giants. He was created from the melting ice of Niflheim.
Muspelheim's heat and Niflheim's ice colided and created the jotunn Ymir and icy cow Audhulma.
