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.

Erasmus is a very laid back dragon, not doing much to stop the newest hatchlings from crawling all over him like a living jungle gym. Occassionally he'll pin one between his front legs and bathe it liberally in slimy kisses, eliciting laughter and mock rage from most. If he is angered he will puff himself up and hiss, spreading his huge wings. He and Obsidion are brothers of the heart, staying near to one another always. He brings choice boulders for Obsidion's sculptures, when he is not busy with hatchlings.
