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.

Delgo is the eldest dragon in the cave and was the first one to have hatched there. Delgo has many children and wants to make his family even larger. As the leader of takalover dragons Delgo does as he pleases and eats first when someone brings back food. As the Takalover cave grows larger Delgo has many younger dragons competing for his role as leader so he doesn't have time to patrol his territory or hunt.
