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.

Adii has always been an aggressive, prideful dragon. He has had a constant rivalry with Magm'Au, a curious magma dragon, whom Adii believes has been placed as favorite by the Master of the Screaming Caverns. Adii has mocked wingless dragons for lack of ability to fly, and has once or twice challenged Nightlinn to battle for right to lead the dragons of the Screaming Caverns, both attempts were miserable failures. Simply, Nightlinn put Adii in his place, now only occasionally Adii acts in these manners towards the other dragons.
