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.

Haku's absolute favorite fruit is white peaches. He can spend an hour slowly gnawing away at a ripe peach, savoring the light sweet taste and the soft texture. Whenever he can, he will save the peach seeds to either carve into ornaments or have jewelers make them into rings. He likes to keep his collection of gems on display with his nicest peach stone rings, since looking at both of those things makes him feel very happy.
