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.

Peyman is a strong-willed and clamorous Pyropellis. When he gets his way, it's often because he loudly reasoned with his allies or teammates until they gave up opposing him out of weariness. Some onlookers might call it bullying, but it's much preferred to the sort of bullying the local hooktalons and royal crimson, for example, engage in. His friends don't deny that he's a skilled strategist and a quicker wit than they, but getting them to agree with him still takes a while. In any group activity, Peyman tends to be the planner, and the only one who remembers what they are doing from start to finish, while the others occupy themselves with distractions such as infighting and going off-path looking for souvenirs.
