While extremely rare and only found in the most remote locations of the galaxy, fiery diamonds are much like red diamonds in appearance, but are used as catalysts to focus power, pyroglytheum, and elemental manipulation. Said to be born from the lakes of fire found in the Underworld, these stones have some super natural maleficent properties about them, and require incredible strength and mental control to be used among tools and weaponry. Only the strongest can wield weapons crafted with these stones, but if used correctly, can harness incredible amounts of power, and can be used to help focus elemental prowess into concentrated power.

Rarely found crafted into swords, these weapons built with these stones are often created with special properties to serve their masters in ways beyond normal comprehension.
