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.

Unlike the Banni-ghymn, the Auvrea-neldth (a surname meaning Blood of the Arcane) only use their knowledge of the arcane for personal benefit. Members of the Auvrea-neldth guild are often cruel and unforgiving. Dragons come here to learn the dark arts of necromancy, destructive elemental magic, and other such morally questionable practices.

The Auvrea-neldth territory is home to one of the only dragon-run apothecaries on Dragon Isle. This shop, run by a Vampire dragoness named Balcthel, is where Morchanar feels most at home. Being a clever creature with an insatiable drive to stand out amongst his peers, Morchanar learned to use the unusually weak venom in his body as a base for making other more potent poisons. He is very fussy about his workspace, insisting that the cluttered mess makes perfect sense to him. If his skill or methods are questioned, Morchanar becomes very impatient and hostile, lashing out both verbally and physically if the questions don't cease immediately.
