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.

"Cold", as she is usually known, spends most of her time near the summits of the mountains in which her egg was found, and, as her name suggests, loves all kinds of cold weather. Whenever a snowstorm strikes, Cold will be out flying in it, generally returning to the clan cave with icicles on the fringes of her wings. Due to this practice, she is excellent at flying and navigating in adverse conditions, especially in low visibility. When she is not away from the cave, she will sometimes help out with the hatchlings' flying lessons—though she tends to forget that the babies are not as agile or speedy as she is!
