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.

Carefully Crimson is a silent and mysterious guy. Nobody knows about his past as an egg still in the cave, except that his parents were a Royal Crimson and a Royal Blue dragon, and that he was an abandoned egg. All you'll hear from him is the occasional grunting, but other than that, he's silent. He will use magic to keep the other dragons away from him, and this works for all of the dragons expect for Amberized the Cassare dragon, who is immune to the magic. Even the female dragon that has taken a liking to him, Purple Dorm the Dorsal dragon, was sent away from him with his magic. He even refused to breed with her to create offspring.

Nobody knows why he's like that. He may have a tragic past, or, he's shy and an emotionless wreck.
