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.

Knightstallion is a vicious and territorial creature who fiercely protects a segment of underground cave he's claimed for himself, which while accessible to other dragons, is very hard to reach due to the sweltering conditions of the river of lava flowing through. The only presence he can tolerate within his own "territory" is that of his father, who freely swims in the lava rivers as he pleases. Knightstallion usually only comes on land to drink or eat (though really he just pulls uneaten food someone else caught down into his cave and eats it there), or simply to wander around in boredom. Other dragons are annoyed by him stealing their catches to eat by himself in his cave, but while they fearlessly voice their complaints amongst themselves, no one ever actually does anything about it in fear of being burned.
