Muspell
The fiery southern boundary whose heat meets Niflheim’s cold and helps first life emerge.

Overview
Muspell is the bright, hot southern world in Gylfaginning 4; its guardian and later doomsday fire belong to later stories. This creation story uses only its opening role: Muspell’s heat meets the rime of Niflheim, and Ymir’s life awakens.
