Surtr is the lord of the fire giants. His animal is the hell hound. His symbol is a flaming sword. Surtr looks like an immensely large fire giant with crackling flames for hair and eyebrows. He wears armor of blazingly hot iron and wields a flaming iron sword 15 feet in length.
Surtr, a son of Annam, is part of the second generation of giantish deities, born at about the same time as Skoraeus Stonebones and Thrym. While Surtr's cult is similar to that of Thrym's, fire and ice do not mix.
Nearly all of Surtr's worshipers are giants, but a select few members of other races have earned his approval. They conceal their devotion to the giant destined to end the world.
At Ragnarok, the battle at the end of the world, Surtr is destined to set the world on fire, burning it to ashes to make way for the new world to come. He will destroy Bifrost, the rainbow bridge, beneath his weight and that of his subjects.
