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.

Neal is one of the many dragons rescued and nurtured by the wide ranging clan of humans founded by AnselaJonla. His egg was found in the jungle and taken to a hatchery to be raised.

Once he matured, he found his lifemate, a Bright-Breasted Wyvern, among the other AnselaJonla dragons. In the tradition of the AnselaJonla flock, both dragons took the same name, Arwen, to pass down to any of their offspring that remained within the flock.

Lazy is the best word to describe Neal. Every morning he feeds, washes in the river, then curls up on a sun-drenched rock and doesn't move until the sun no longer bathes him in light.

This laziness means it always comes as a surprise when Neal joins in a battle to defend a hatchery. The first warning anyone ever gets of his presence is his spined tail ripping into unprotected flesh. He'll aim for the throat if he can, but the toxin on his spines means any blow will eventually kill.
