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.

Acanthus is the master architect of Fengari's troupe. He's the one that designed and built the artificial cave system in Cave Mountain for the dragons to live in, and he's always thinking about the best way to expand it when the troupe gets bigger.

He doesn't like that the Embers claim that the rough, natural caves near the top of the volcano where they choose to live are better than the ones he so lovingly designed.

He is very fond of Accalia as he adores her beautiful earthy colors. He treats her like a little sister, because they hatched on the same day and grew up together.

He fell in love with Alcee, the young Stone dragon that started to follow him around when he was working on the caves, eating the debris he left behind. That theirs is a perfect match was soon confirmed with two crystalline young ones.
