Tiamutan Stone

Tiamutan Stone is quarried and mined by the murderous tribes of Goliaths and Giants in the Stoneshaw Hills. Negotiating with these violent races is always difficult, and as they are the only creatures who can work the monolithic blocks they drive a hard bargain. Therefore, it is monumentally expensive to build anything out of it. However, once in place it is said to be as hard to damage as Tiamut herself.
