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.

Some dragons get very easily stressed. Phlogiston is one of those dragons. There are almost always eggs to keep warm in Nadat's cave, and she spends a great deal of time worrying about them. She wonders if they're warm enough, too warm , if they're upside down, if one hatches while she's not watching and wanders out of the cave to go elsewhere, and so on. Sometimes when Phlogiston is worked up she'll seek out her best friend, the Night Glory dragon Serenade, but at other times she winds up traveling a bit away from the cave and letting off steam by setting things on fire. It works, for a while. But by now every dragon in the cave knows when to say hi, and when to get their tails out of her way, based on her facial expressions alone.
