Hellhorse Dragons are foul-tempered, spirited creatures with tempestuous and violent dispositions. Torrents of scorching flames erupt from their bodies and can easily set their surroundings ablaze. Highly aggressive and territorial toward other dragon species, Hellhorses will tolerate others as long as they believe the association to be beneficial. Such alliances are tenuous in nature and frequently short-lived, as the slightest disagreement can easily escalate into a full-out brawl.

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.

Raging Cinder is the impulsive, high-spirited daughter of Night Puka and Firebird Heart. Quick to anger, she has been known to go on a rampage over the smallest offence. Incidentally, there is a permanent scorching trail winding around the volcanic valley where Raging Cinder's parents live, a place where no vegetation ever grows. This trail is a relic of Raging Cinder's turbulent adolescence. Because of her wild nature, which only intensified when she reached adulthood, she rarely remains near her birthplace, preferring the freedom that comes with being a vagabond. However, she will always return to her childhood home at least once a year in order to see her mother and father. The reason for her regular visits are not out of homesickness, for she is perfectly happy to be on her own, as far away as possible. In actuality, she knows how Night Puka and Firebird Heart have always wondered about the whereabouts of their own parents and that they therefore place a high value on family ties.
