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.

Sebastian is best known for being the leader of the notorious Hellfire Club, which is an organization of dragons who specialize in making the world a worse place for those who disagree with them. As implied by his position, Sebastian is a black-hearted dragon who delights in seeing his enemies vanquished.

Despite being in a position of power, with many dragons under his command, he hasn't become arrogant; he's always planning for every possibility. That's what has made him so dangerous and so seemingly impossible to defeat.
