Dragons, rare and huge and beautiful. They have scarcely been seen for the last fifty years or so, as there numbers dwindled. They have almost been relegated to legend. Younger generations of humans believe them extinct.
Males can reach up to 30 feet long, maybe more. At one point long long ago, they sometimes worked together with humans, however, recent memory recalls them as a vicious enemy that would torch whole villages and raid caravans to steal the rich goods traveling along isolated roads.
Humans in turn hunted them down to steal there hoards.

Dragons can be extremely long lived (if nothing bad befalls them). They also have certain abilities like shape shifting that help them hide and adapt to the world for survival. They are very private and secretive, not liking anyone, even other dragons to know where they live or what special skills and abilities they may have.
They like to make their dens in caves or ancient ruins. Preferrably any place that is hidden away and not easy for humans to get to.
Their babies have an especially long childhood and usually stay with their mothers (or fathers in some cases), for several hundred years until they are fully grown.
