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.

Zarrul, unlike most of the other residents of Fireflood Weyr, doesn't specialize in fire magic. He uses fire, yes, but he uses it to forge metal for his many inventions. Zarrul has created devices to keep a lair cool, to repel insects, and to chill food, and there seems to be little limit to what he can construct, given enough time and material.
