Pyropellis Wyverns are most commonly encountered swooping through the trenches and craters that dot their volcanic abodes, bathed in stifling heat. While their tough, mottled hides blend in seamlessly with the volcanic rock that surrounds them, Pyropellis Wyverns stand out due to the fervent flames that cloak their backs. Unable to produce a flame, these dragons secrete a highly flammable substance from their backs, which they will find some way to set alight. This fire primarily serves to intimidate and daze unfriendly strangers, keeping snapping maws away from the necks and back of the dragon. The flames also serve as a way to bond: young hatchlings are often first set aflame by their parents. Fire-breathing dragons may supply their mates with flames. It is not uncommon to find a Pyropellis sporting flames unique to other species of dragons, having made contact with those flames.

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.

Yadzu and his mate, Seigyo the Magi Dragon, are frequently charged with setting up amphitheaters in the family's volcanic territories. Whenever a family event or celebration calls for performances, Yadzu and Seigyo scout for venues based on the guest attendance expectations. Yadzu plans the seating arrangements and helps train ushers to manage guest traffic, while Seigyo casts enchantments to generate grassy hills and mounds to serve as seats and tables. During the actual events, the two are rarely present amongst the festivities; rather, they are typically seen perched on nearby cliffs or hovering in the sky, keeping an eye on their preparations and swooping in to assist if something goes awry.
