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.

Known to nearby villagers as "Thunderer", this dragon is a possessive and territorial beast.  Having made his den in a secluded swamp cavern, he quakes his land to terrorize travellers trespassing on the treacherous path through his bog.  These reckless displays of power attracted Azagwid Mirra to his side, a proud daughter of the gold Swift Mirral.  As a vicious defender of what is his, Leithyr goes to great lengths to provide for and protect his dependent young and their mother.
