When the Giant army was defeated in the Third War, most of its survivors fled back to the north. Instead of leaving the continent, they settled in the Arctic and adapted to the cold environment—unnaturally quickly. Rumor has it that they still live there in great halls of ice, battling the High Elves in their new home.
Frost Giants are great towering men and women, at least fifteen feet tall, with more than enough muscle to match their height. They have become creatures of the cold, with hair and skin in shades of white or blue. They typically wear enormous suits of mail and helmets mounted with the horns of great beasts.
Frost Giants are dangerous and aggressive. They’ve made it quite clear that elves are unwelcome in their lands.
