The collosals are an ancient race perhaps dating back to creation or only as recently as the dragons war. Many believe they were created as weapons. The size of mountains and seemingly bereft of conscious thought they will aimlessly pace a region for hundreds of years before suddenly changing direction to again pace over new ground. Their massive size makes them immune to the weapons of mankind save for the most powerful of magics that few can wield. Often even with the use of those magics little can be done but to turn them away from places that they could do harm. A single footfall is enough to crush an entire village beneath it.
