Muspell

Muspell are flame-based Demons related to Iblis, the King of Fire.

Overview
Muspells appear as titanic humanoids made of molten rock with a single flame rising from their heads. While they seem to possess a pair of eyes, they do not have any other facial features. Unusual for demons, each one seems to come equipped with a weapon, a spear made of flame. When damaged, their bodies seem to break down into rock.

Powers and Abilities
Giant Size: Muspells seem to primarily take advantage of their large size in combat, able to pick up targets easily or simply obstruct paths like a living wall.

Trivia
