Red-Tailed Wyrms are a small but clever breed of dragon. Their innate ability to use air mana allows them to fly, and they are aerial predators with extremely sharp eyesight. They tend to ride on warm air currents, and then swoop out of the sky when they spot prey. Once the wyrm catches its prey, it will constrict its meal before swallowing it whole. They can often be found in human settlements, draped over rooftops or signs to rest between meals.

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.

Pygmy dragons are the smallest category of dragons, being on the same scale as domesticated animals. They are often found around concentrated populations of dragons, relying on their larger brethren to ward away potential predators and leave scraps. As such, the majority of a pygmy’s diet is scavenged. Due to their tiny size, pygmies do not breed with larger varieties of dragons.

Astali was the first Red-Tailed Wyrm to take up permanent residence in the Clan's Desert March, after having moved in from the unknown wildernesses beyond. She is known to be a nervous and frantic creature, easily startled by others, but can be inquisitive so long as her object of curiosity makes no sudden sounds or movements. She frequents the glass citadel in the march but never dares to actually go inside it.
