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.

Bloodruby likes the lava. He spends most of his time in the lava and tries to hoard the best things—prey, what treasure he can find, spots in the lava pools, etc. However, Bloodruby is pretty laid-back and lets other dragons hang out with him, as long as they don't try to steal anything. He doesn't like the aggressive dragons much, but that's because he always thinks they're trying to take something from him when they set him on fire or try to roughhouse with him.

What he does like are Mint Dragons, which try to hide from him because he is so big and they are so nervous.
