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.

Someone is pretending to be WOUDO. WOUDO is trying to figure out who and stop them, but she keeps finding strange charges to her account for mail-order products that she did not ask for nor receive. The problem started with coins vanishing from her hoard, so suspecting a misfit sneaking into her weyr she started banking with the the Centavo Credit Union. Then the mysterious orders began. She became suspicious of the teller and switched to banking with another group, but the charges continued. The bankers there claim she is buying things herself and lying to try to get a refund, which she denies. Nworset City's police are currently investigating the problem, and hope to catch the pseudo-WOUDO soon.
