Nhiostrife Wyverns are one of the few known breeds of wyvern with more than one set of wings. Because of their four wings, Nhiostrifes are very nimble in the air and control their movements with ease. When it’s mating season, males put on a very beautiful and unique air dance in an attempt to charm a female. The amount of stripes on their wings vary, with more stripes being more attractive, although most have only two to four. Their general attitude is very passive and curious—they only fight if they or their families are in danger.

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.

Ou-um-oh considers himself a mystic dragon. He helps other dragons get in touch with their mystic spirits by performing a tight dance directly over their heads. He is careful to swoosh his wings, sprinkle aromatic powders, and chant "Ou-um-oh!" throughout the ritual. Those he dances over get dizzy trying to watch the swirling stripes on his wings and inhaling the powdery scent. They usually hallucinate and believe they meet their spirit guide thanks to his ministrations.

When not performing his ritual, Ou-um-oh is often busy with gathering the components of his aromatic powders or eating frogs. He believes the frogs' ability to jump helps him to be more dexterous in the air after he eats them.
