Aegar

Aegar, the Freezing Flame is a giant wizard from Kaldheim.

History
Kaldar, the king of the fire giants, had a secret affair with one of the frost giant matrons. That affair produced a child: Aegar. Aegar possesses the measured temperament of the frost giants, the combat aptitude of the fire giants, and the elemental prowess of both. Raised among the frost giants, Aegar didn't discover his fire giant ancestry until his powers manifested as an adolescent. He immediately set off on a pilgrimage for the fire giants to find and meet his estranged father. He was met with derision by some of the fire giants but quickly earned his place by handily defeating those who disparaged him.

After making a scene on his arrival, Kaldar came to investigate. A brief conversation revealed their relationship, and Kaldar was overjoyed to meet the son he didn't know he had. Aegar has found a home for himself in both tribes and hopes to one day unite all of the giants.
