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.

Morden has a rather bleak outlook. He doesn't see the point in hope, or fighting against the inevitable. For this reason he doesn't get along with many in Nadat's cave. Sometimes he's closer to Lord Refa, the Red Dorsal, or Londo Mollari, the Gold, but most of the time he spends his time in the darker, shadowy portions of the cave, contemplating what he wants.
