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.

Doug Rattman, or Ratman, as he's better known, was one of the few survivors of the cave after the psychotic newcomer decided to kill everybody with neurotoxin. He's always been extremely paranoid, for good reason, and carries a cube on his back everywhere he goes, his only companion giving him advice to help him trek around the secret tunnels in the walls of the cave. He writes all over those walls, because that's the way he is, but also to help any other survivors make their way through safely. Before they all died, Ratman's colleagues assumed he was crazy, and his companion cube can't actually talk, but he's not crazy.
