Frost giant

Frost giants (or ice giants) are giants inhabiting the far northern mountains of Nordheim. They are the sons of Ymir and the brothers of Atali. Despite their size and strength and divine parentage, frost giants may be slain with mortal weapons. Conan killed a pair of them during his pursuit of Atali.

Description
Frost giants resemble gigantic Nordheim warriors wearing armor and helmets and wielding weapons (usually axes). Their armor is white with frost, and their helmets and axes are covered with ice. Their hair is sprinkled with snow, and in their beards are spikes of icicles. Their eyes are cold as the northern lights, and their voices are like the grinding of icebergs. They take the hearts of their human victims and lay them smoking on Ymir's board for him to feast upon.
