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.

Arbustus is an overbearing and often pushy female unafraid of giving her opinion.  Although Galbinus is often found in her company, some whisper that perhaps she forces herself on him more than he chooses to be around her.  She is quick to force eggs out of the shell using her violent earthquakes and if there are a few casualties of her impatience, then so be it.  She isn't particularly concerned.

The meaning of her Latin name is 'planted with trees'.
