Turpentine Dragons are named for the oil that covers their scales. This oil resembles turpentine in odor and is mildly toxic; it will not kill but it burns to the touch and will cause illness in anyone who ingests it. Turpentine Dragons roam in large packs, often stealing food from larger dragons, though they are able to hunt for themselves if necessary. Many other breeds consider Turpentine Dragons to be pests, so they primarily breed among themselves.

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.

Rainbow and his mate, Imboreda, are spontaneous and random, performing actions on impulse rather than thinking about the consequences. This can lead them into all sorts of situations, from positive to deadly (usually deadly). However, they always manage to make emerge from the turmoil unharmed. Beyond the impulsive behavior, they act like fairly normal Turpentines. They will steal food (and other things too- from common rocks to eggs and even live hatchlings) from under dragon's noses, and will hunt with other Turpentines. Rainbow and Imboreda do not care where they spread their turpentine-like toxins, resulting in many dragons having a burning feeling in their feet. Of all the Turpentines, they are considered the most pest-like, and are despised by many. Luckily, they can be easily avoided, as they announce their presence by making high-pitched shrieking noises and spouting random gibberish in telepathy to any and all living creatures nearby.
