Geode Dragons are closely related to Stone dragons. They are covered in a hard stone-like material as well as beautiful crystal. Their wings are entirely useless for flight, but they help attract mates. The dragons with the most brilliant and colorful crystals are more likely to mate.

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.

Blue Stone Heart is quite the character.  As an egg, he was accidentally knocked with a tail, causing him to roll out to the mouth of the cave, where he was found by a human.  Because he was the first in a new cave, he has become the unofficial leader for the cave.  When a hatchling with new wings, he once tried to fly, but was unsuccessful because of his breed.  Since then, his feet have remained firmly on the ground.  His crystals attract many female dragons, but his sights are set only on Memory Alpha.
