Stone Dragons have a tough outer covering made of a stone-like material. They eat rocks, using the minerals they contain for nourishment and to keep up their stone outer shell. They rarely move, and are the heaviest of all types of dragons. Although they have wings, indicating flight ability, no one has ever seen a stone dragon flying.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Karnar is actually a name of a rock this stone dragon has been thought to be. For years humans haven't noticed that it is actually an unbelievably huge creature which only moves during the night to feed.

The only person that knew this was a mage living on Karnar's back. It was him, who revealed this to people when they asked him about his rock going missing during the night. First they were shocked, they feared Karnar, the Dragon Rock, as they called him, but soon, when they found out his peacefull, calm and human-loving personality they learned the benefits of having a big scary dragon near them (for it would be rather unwise to try to plunder a village proted by a huge dragon).

Now Karnar is being visited by the bolder of people at night, and the less brave often come to admire him during the day.
