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.

The lore of the Spectrum Clan, commonly believed by villagers, is that the members are grand heroes and warriors that were reborn as dragons. Many people who live close to the clan's territories would observe them and notice that some behaved uncannily like the heroes talked about in stories or, in some cases, have powers similar to these legends. Whether these Spectrum Clan members are draconic reincarnations of brave heroes or if it's simply coincidence is unknown.

Emerald Firestone is the most well known example. He is very strong, even for a Green dragon, and is capable of lifting boulders the size of a whale. He can even take on ten Brute dragons on his own without barely getting a scratch. Though his strength is widely praised by his clan members, Emerald usually does smaller tasks for the clan like moving rocks from an avalanche. He likes accepting any challenges from other dragons.
