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.

Vulcanica is the most matriarchal of all Ran's dragons.  She is also the most stern female in the clan, teaching the hatchlings about old legends and the earth around them with a no-nonsense attitude.  She greatly respects Winged Nimbus, as she is the White dragon's second-in-command.  The middle-aged Earth dragon is entirely responsible for creating the expansive rock walls closing in the home cave and Aquari Neptune's lake.  Only leaving the home cave to maintain these walls, she is the main caretaker for the hatchlings, and despite the fact that she trusts all of her siblings fully, Vulcanica can't bear to see them in the care of another.
