Fire Giant

Dark-skinned with bright red hair, Fire Giants are an odd sight, albeit thankfully a rare one. They live far underground or near volcanoes, anywhere where the blood of the earth is readily available. They are the smallest of the Giants, but no less dangerous for it. Masterful smiths they are, even if their talent is mostly used for making weapons and armour. Of the all the Giant races, these ones are likely the cruellest of them all: coming to the surface to raid and enslave, making their captives work in mines and forges to keep their dark industry moving along. These giants are no less magical than their more intelligent cousins, having an innate mastery over flame and heat. Fire Giants are dangerous enemies, ones better avoided if at all possible.
