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.

A conniving and greedy wyvern, who would be much more of a threat if he didn't have the approximate mental capacity of a squirrel. Misojo is somewhat of an oddball among the clan, usually found skulking about rather than socializing. He seems to have aspirations of seizing leadership for himself, which is difficult when a stern look from Oevina is usually enough to put him firmly back in line. Fortunately, it apparently hasn't occurred to him that the venomous sting he uses on his small prey could also be used on dragons--or perhaps even he knows that if he tried, the others would rip him to pieces.
