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.

Since the day she hatched, Irides was the target of endless torment and harassment. Not only was she born with solid wings, something that was viewed as the deepest shame in the dragon clan, but all the other eggs in her brood never hatched. For that reason, she spent nearly every day with the other clan's dragons telling her that she shouldn't even exist. Despite the best efforts of her parents, who did their best to ensure their only hatchling knew they loved her unconditionally, Irides' self-esteem was in tatters by the time she grew her second pair of wings. Unwilling to continue bringing shame to her parents, she left the clan one night. While she had no intention of ever letting another dragon see her ever again, this changed when she had an accidental run-in with Rockjaw. Upon realizing Rockjaw had also been ostracized due to his appearance, she eventually accepted his invitation to join Sol Orb's dragon clan. Even so, it took her a while before she spoke to anyone but Rockjaw.
