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.

Dancing Nightmares is an interesting wyvern, to say the least. His courtship dances do not seem graceful at first, with jarring sharp turns and steep angles; in fact most of them seem unpracticed. However, once everyone watches for a bit longer, people learn it's a part of his charm. Not every dragon can turn on a dime and he flaunts this to make sure the females understand what they're getting when they mate with him.

He has a large silver necklace he will wear sometimes, the reflectiveness of it adding to the charm of his dances.
