Stone Dragons are black or dark grey in color, and adult males are generally 40 to50 feet long.  They have the strongest scales, and can withstand enormous strikes.  They also spew fire, but their natural supply of inferno is less than both the Great and Fire Dragons.  Being so heavy, they don’t fly as well as other Dragons.  Stone Dragons can’t swim at all (even in human form), but can walk across the bottom of a river.  They can hold their breaths for much longer than other Dragons, and are generally considered to be fire-proof.  Stone Dragons should only be found west of the Amber River, in Baize.  Stone Dragons are generally considered to be slow-witted.  In human form, they have black hair.  They only eat meat.
