Royal Crimson Dragons are so named due to their massive size and confident, regal bearing. Most of the time they are laid back, ignoring non-prey creatures smaller than themselves, although they will occasionally take fresh kills from other dragons as a reminder of their place in the social order. Although there are few other dragons large enough to pose a threat to Royal Crimsons, they have little tolerance for potential rivals and will fiercely defend their territory from such intruders.

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.

Many dragons in the cave envy Adelfonsus because he seems to be good at everything he does. He is a skilled hunter, a graceful flier, and one of the best fighters. He never seems to struggle. What they don't know is that Adelfonsus is very good about keeping his failures secret. He practices hunting and flying when no one else is around, and he only practices fighting with a few trusted friends, who won't make him feel bad about losing. Ultimately, he is very prideful and at the same time very sensitive, and doesn't like others seeing his mistakes. Because of that, he also tries his best to be humble and not talk a big game.
