Flamesmith

The strongest weapons and armors in the Burning Lands are crafted by the Ferox, a silent race of fire people who live beneath the mountains. A Ferox body consists of flowing magma held together by a single ferox stone that sits at its core. If a Ferox is killed in combat, its ferox stone ceases to glow, the magma cools and stops flowing, and the two horns fall to the ground. Ferox are made for the forge; they can handle superheated metals with their hands, and they can harden and reshape parts of their bodies at will. This means that a Ferox blacksmith not only has all the tools it needs. It is the tools.
