Muspelheim
Muspelheim is one of the Nine Realms in Thor: Ragnarok, a world of fire and black rock above open lava, home to the Fire Demons and held by their lord Surtur.
Muspelheim is one of the Nine Realms. It is a world of fire, its surface broken into shelves of black rock standing above open lava, with ash in the air and a red sky over the peaks.
The realm is home to the Fire Demons, tall creatures of stone and flame who muster in numbers across its ridges, and it is held by their lord Surtur, a horned giant whose throne sits above a vast chasm at the heart of the realm. The heat and the inhabitants together make Muspelheim hostile ground for anyone not native to it, Asgardians included.
