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.

Kruhr Hravi means "Red Prince, the Wild One".

He bears the title of Kruhr the Defender, rightfully earned from his heroic deeds of defending the Volcanic Regions from a rogue clan of Hellfire Wyverns. Kruhr, born in the Volcanic Regions, sees himself as the Master of those lands. Upon seeing a mighty army of Hellfires bursting out from a crack on the ground, Kruhr took it upon himself to defend his homeland as well as the dragons who lived there.

The great siege lasted for three months; during which Kruhr and Nyx, a Black Dragon, fought bravely and fiercely to stop the Hellfire Wyverns' destructive antics. Afterwards, he merely shrugged his massive wings that casually canopied Nyx, and growled: "Those screechy males are too big for their claws."

Kruhr is the first of his line, and all of his descendants took the name of Kruhr as a prefix name in his honor.
