Falconiform Wyverns are normally shy creatures. However, when approached, they often feel threatened, and the flames along their bodies leap higher. Females tend to be smaller than males, though Falconiform Wyverns are typically rather large overall. They use their size to their advantage by hunting smaller dragons. The Falconiform’s graceful, swooping dives are said to resemble birds of prey. Falconiforms are largely solitary dragons that only meet in order to breed.

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.

Cold Eggnog has expensive tastes, which is unfortunate because he has no source of income. He has skills such as quiet flight, "cool" fire tricks, and killing things, but he doesn't like to work for anyone, or work at all. He is a "familiar", which in Glenelise means he gets free food and a dwelling but has to obey his master and doesn't have any money of his own. He's always devising ways to spend his master's money on expensive things without her rebuffing his attempts or tightening her purse.
