Surtur stands ever alert in Muspelheim, brandishing his sword that shines brighter than the sun. At Ragnarok he will be responsible for setting the world on fire, burning it down to make room for the new one. Prophecies say that he will even destroy Bifrost under his weight and that of his subjects.
A few cults of Surtur thrive in Mannheim, often cooperating with Loki’s cult. These cults teach respect for fire, its use as a tool and its danger when uncontrolled. They teach that fire is a cleansing agent, and point to the new growth after a forest fire as proof. Members of Surtur’s cult seek every opportunity to undermine Thor’s cult, and they have plenty of help and expert advice from Loki’s cult. While Thrym has a similar cult, fire and ice never mix.
Surtur rarely grants divine power except to giants. However, a rare few individuals in Mannheim have earned his approval. They conceal their devotion to the giant destined to burn down the world.
Surtur’s temples in Mannheim are hidden affairs, much like Loki’s. In Muspelheim, they are enormous fortresses that ring with the sound of the forges day and night. Surtur’s Muspelheim temples are centres for preparation for Ragnarok. Temples in Mannheim secretly store weapons in preparation for the cult to fight alongside the giants.
Visitors to Surtur’s temples have only a few seconds to prove their devotion to Surtur before the members of the cult attack. The clergy and the members of the cult in Mannheim do not leave witnesses alive to report their activities.
