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 Silver Sheen is named for the deadly illness carried in the spines of his tail, which often causes his prey to quickly gain a fever and begin sweating profusely. Not much is known about his particular illness, besides the fact that the sweat that the prey produces- no matter what it is- has a silvery sheen to it. The sweat is capable of passing on the illness as well, and many creatures die within hours of contracting such a disease. A Silver Sheen does not like to be around others, but despite this, is very playful and light-hearted.
