Skywing Dragons spend most of their lives flying in the air. They hunt from the air, diving at prey from above, and land only to rest. They are some of the fastest fliers, capable of extremely high speeds. The webbing at the end of the tail acts as a rudder, allowing them to easily change direction during flight.

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.

Gathering information from generations of solitary flying and exploring high above any inhabitable land, he carefully studied humans and learned much of their customs and behavior towards dragons. Although he has skepticism towards humans he trusts one, Arashi Hageshii. Stopping only to eat or sleep, he is rarely ever seen anywhere else but in the clouds and answers to no one, not even Arashi. He suits his name well as Ilhuicateotl is directly translated to "God of the Skies".
