Jarl Aegir Frostbelly is the king of the frost giants. They live deep in the northern mountains of Niflheim, one of the coldest and darkest places in the realm. Aegir is feared not only by his fellow frost giants, but anyone who dares live within his territory. He towers over 20' tall and weighs in at nearly 1.5 tons.

Aegir's thirst for blood and wealth knows no bounds. The nearby town of Midgar makes sacrifices to keep his forces from raiding and pillaging at will. When the townspeople fail to meet his demands, he descends upon the town, hurling giant frozen boulders and laying waste to the townspeople with his enormous battleaxe. Aegir is also known to summon tsunami waves to wreck cargo ships, and then plunders any treasure they may be carrying.

The Jarl's ancient enemy is the Spirit of the Forest. Her and her allies to the south keep Aegir from expanding his territory into the forest lands. If it weren't for his weakness to the Earthen elements, his empire would be ever-expanding.

Aegir maintains relations with the Forces of Fire, because of their weakness to his Water and Ice abilities. In return for the homage they pay him, he will not attack unless provoked. Sometimes, he will call upon Fire Demons to set ablaze the local villages to not risk losing any of his own forces.

The ancient dragons will sometimes pay visit to Aegir and trade goods. They have a respect for Aegir because of their equal lust for power and glory. When the Forest people push Aegir's forces back, he will bribe the dragons with Gold to have them join forces.
