Each Fever Wyvern carries a unique and very deadly disease on the spines of its tail. To make up for a lack of physical strength, the dragons use this disease to their advantage by poisoning prey and fending off attackers. The illness will quickly render victims helpless before eventually killing them. A Fever will track its prey until the target can no longer move. Usually a solitary breed, these dragons will only come together during mating season, and will flare out the brightly colored sails along their wings to help attract potential mates. Although it has been observed that the wyverns are nocturnal, they will often pick an open spot of sunshine to curl up in and sleep as the day passes by.

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.

Flares is a smart, kind, and sometimes clumsy Fever Wyvern. Flame Dorkwed, a female Magi, is his best- and only- friend. He and Flame have been through thick and thin and have never failed to be friends. He and Flame had an egg by accident once. It was up to her to abandon it, and Flares didn't tell her whether he wanted to keep it or not, but Flame did abandon it, to Flares's liking. Flame now refuses to mate with any dragon, including him, and he does too, but he realized after the egg was abandoned that he loved her. He keeps his crush deep inside his heart and knows that he can never be her mate, but he tries to be the light of her day whenever he can. This proves to be very difficult for Flame, as she is aware of his crush, and although she likes him she doesn't love him that way... yet.
