Red Dragons are similar to typical story book dragons. They shoot flames, can fly, etc. However, they aren’t evil creatures as depicted in myths and won’t go around raiding castles, killing knights, or kidnapping princesses. They live in a variety of habitats, from forests to coastlines to abandoned castles, usually in warm climates, and eat whatever living creatures they can find.

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.

Trailer keeps all of Wendy's costumes in his cave, storing them for whenever they might be needed by the members of the Crimson Players. He's rather compulsive about keeping everything neat and orderly. Every piece is catalogued and its information given to Scribe to add to the wardrobe spreadscroll so Wendy knows what she has and where it can be found. Whenever he's stressed, Trailer goes into his cave and relaxes by admiring the rainbow hues of an orderly wardrobe.
