Thrym

Thrym was a titan worshiped by the frost giants   as the giant god of cold and ice. He was the de facto leader of the frost giants as well.

Realm
Thrym ruled the realm of Fimbulwinter in the Elemental Chaos, described as a wide tundra illuminated by sparkling frozen waterfalls. His stronghold and festhall was called Nyfholl. In earlier cosmological models, his realm was described as mountainous but still filled with snow, ice, frost, and glaciers.

Description
Thrym appeared as an exceptionally large frost giant. He typically wore chainmail and a coat made of white fur.

Personality
When not directly preparing for war, Thrym was known to be fairly aloof, wandering his realm restlessly.

Abilities
Thrym could breathe a devastating cone of cold out to 100 ft (30 m) and was completely immune to cold- or ice-based attacks. Only highly magical weapons could even touch him enough to injure him. He often granted frost giants the ability to use arcane magic like a wizard.

Possessions
His signature weapon was a large double-bladed greataxe.

History
At some point Thrym forged a magic warhammer by the name of Matalotok.

Relationships
Thrym was a son of Annam All-Father.

Thyrm was known to have a rivalry with his twin, Surtur. Since birth, the two had competed to be the first at everything.

At some point, Thrym fathered the Empyrean Nalkara with Auril, goddess of winter.
