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.

Named for the many bloody battles that have occurred on Sundays throughout history, Red Sunday is almost the polar opposite to her name. Since she was the first of Stellar's dragons to hatch a clutch, she has become something of a mother figure. She can appear fierce when she chooses, but of Stellar's dragons, she is the one who spends the most time tending to eggs and hatchlings when Stellar is not around.
