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.

As a hatchling, Ziho was constantly sick, and always having to be rushed off to the steam room for treatment. The steam room was a tall room with a pool at the bottom, with a woven grass net separating the top half from the water. Healing herbs would then be placed in the water, which would be heated, surrounding the hatchling with the herbal steam, making the hatchling appear to be fogged. Ziho adored this treatment as a child, and frequently will pretend to be sick in order to return to the steam room, loving the feel of the hot gas rolling over her scales. Sometimes, once the pool has cooled, Ziho will dive into the still warm mixture, bathing on it for hours on end until the water is long cold. Ziho believes that this will give her many health benefits, such as a more youthful appearance and shinier scales, so devotes herself to this regime. She will frequently bring up her "healthcare secret" in conversation, longing for people to question her about it.
