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.

Guyanothaz thinks highly of himself, and often lets others know what he thinks of them, since he knows there's very little they can do to stop him. Being very proud, anything he sees as an insult to him will be revenged, usually in the form of a rain of insults followed by him stealing the targeted dragon's fresh kill or newly-gathered greens. He rarely ever eats what he takes from these victims; he just takes it to show them where in the chain they belong, below him. The only one he'll listen to without brushing them off or shoot hurtful remarks or comments at is his mate Arsekaslyx, whom he would give up his life for if it would save her.
