Green Dragons are also sometimes called “earth” dragons. They usually live deep within caves, and have power over the earth. They are capable of launching boulders at high speeds, and can cause earthquakes by slamming down onto the ground.

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.

It's not too hard to find the location of Tharkana's area. One just has to look for the absence of intelligent life close to numerous crags and canyons, as if the world itself had shattered. A cruel and malevolent dragon through and through, this dragon prides himself only on seeing how "funny" it is to see things get destroyed. Using his magics, he enjoys devastating any form of life that merely comes close to his region. Earthquakes to watch them fall into the depths, stalactites suddenly piercing their veins, boulders crushing unwitting beings... He seems to invent more methods of dealing with any visitors as time proceeds. For that matter, "Tharkana" is merely the name given to him by the outlying towns, as no one has spoken to him and survived. The few brave enough to attempt slaying him have never returned. Even his cavern's entrance seems to change position from day to day, lending credence to the rumor of him using his spells to change his den's layout to confuse the unwary.
