The fire giants, or muspilli, are eager participants at Ragnarok and believe in the fiery destruction of the cosmos. The most famous of the fire giants was Surtr ("black"), a jarl who guarded the gates to Muspellheim. He had burning hair, skin of boiling lava and carried a flaming sword. Muspellheim was one of the "middle levels" of the Nine Worlds, along with Midgard and Jotunheim.
