Muspelheim
Muspelheim is one of the Nine Realms, and is located in the lower region of Yggdrasill, on the same level as Niffleheim.
Following the Conquest of the Nine Realms, it was made part of the Asgardian Empire. It is represented on the Congress of Realms by one congressperson, First of the Flames.
Geography
It is a realm of eternal fire, and the home of the Fire Demons and their ruler, the Fire Giant Surtur. The surface is covered in pools of lava and giant flame pits.
History
According to a cosmology common to many of the Nine Realm, the Ginnungagap was the vast primordial void that existed prior to the creation of the manifest universe. In the northern part of Ginnungagap lay the intense cold of Niffleheim, and to the southern part lay the equally intense heat of Muspelheim. The cosmogonic process began when the effulgence of the two met in the middle of Ginnungagap. This created the Nine Realms.
