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.

Arion is the serious one in the leader trio of Rockclan. He's a fighter who stands up for his friends and is fierce in battle. When defeated, he is still graceful, earning many dragons' respect. His glowing scales light up the many caves in Rockclan. Thus, his birthplace is known as the Glistening Caves.
