Pyrovar Dragons live at high altitudes in areas with lots of volcanic activity. They are commonly associated with geysers and hot springs and enjoy soaking in the scalding water. Females bury their eggs in these areas warmed by geothermal energy and abandon them soon after. As a result, these dragons are territorial and solitary from a young age. Despite their affinity with water they have powerful flame breath and fire magic. They are entirely carnivorous and utilize a variety of hunting styles, from chasing down prey from the air to lying in wait beneath the water’s surface to ambush any unwitting creatures that wander by.

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.

At the mandate of the GoN (rather, a fragment of towel believed to be inhabited by the GoN), Cause joined a community of dragons as a hatchling despite his solitary nature, believing that is his place. He used to be more outgoing, but years of watching over other dragons' children and witnessing them die in stupid incidents as adults or otherwise be unproductive members of the town has made him angrier and more cynical. Because he still does most things on his own and dislikes talking about himself, it is long believed that "Cause" is an alias because he truly doesn't want to get known in his community.
