Rock dragons (Draco saxum) are among the most enormous dragons, dwarfing trees, humans and other dragons by over three times a normal dragon's size. However, despite their intimidating appearance, rock dragons are gentle giants.
The very first rock dragons (also called stone dragons or colossus dragons) appeared in Russia around the time of World War II. Their colossal weight was enough to trigger large earthquakes in many parts of Russia. Frightened for their lives, many people moved away from the country.
Eventually, by the end of the war, the Soviet government figured out what was going on and set out to exterminate the rock dragons, deciding not to inform the public of their discovery. Their bullets could not pierce the rock dragons' hides but a high-powered drilling machine was enough to break apart their stone armor. Rock dragons fled Russia and moved into the more comfortable Andes Mountains, where they are most commonly found today.
Most rock dragons are the size of several dragons stacked on top of each other. They have massive "shells" on their backs, sometimes with large rocky growths on top of them. Instead of scales, they have large overlapping plates of stone, which offer good protection from their smaller predators and protects their immense bodies.
Rock dragons' legs are short and thick, with four stubby claws. It has no breath weapon, so it relies on its giant paws for its main defense. When it swipes them back and forth, dragons scatter or are crushed by their weight. However, rock dragons are a peaceful race, only fighting the darkness dragons.
