Spinel Wyverns are small, sleek dragons that zealously collect spinel gemstones to line their nests. They are very affectionate with those they bond with, and will happily spend hours grooming a dragon of a different species if allowed to. Spinels are well-known for their even temperament, but when offended, they are very slow to forgive and will never forget. These wyverns will readily perform tasks in exchange for spinels, and occasionally other stones. Occasionally, they can be born with iridescent pale green scales instead of the usual rich red-violet.

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.

In Pale Green's tunnel are two piles labeled "Good Stuff" and "Meh Stuff". The only things that go in front of the Good Stuff sign are spinel gems, ores containing spinel, and her pet rabbits—though the last of those items like to flee from the pile and frequently have to be replaced. Anything else the dragon finds (aside from food) is temporarily placed in the Meh Stuff area and is given away for free, even highly-sought-after items like mana gems and phosphorous. Pale Green does not like complication, and figuring out how to trade or house many types of goods is complicated, so she simply gives them to any nice individual who asks politely. She has a lot of neighbors in tunnels close by who keep trying to peer into her home to see if she has any new Meh Stuff.
